    In this paper, with sophisticated modification on modal-field distribution and introducing new design procedure, the single-mode fiber with ultra-low bending-loss and pseudo-symmetric high bit-rate of uplink and downlink, appropriate for fiber-to-the-home (FTTH) operation is presented. The bending-loss reduction and dispersion management are done by the means of Genetic Algorithm. The remarkable feature of this methodology is designing a bend-insensitive fiber without reduction of core radius and MFD. Simulation results show bending loss of 1.27×10-2 dB/turn at 1.55 μm for 5 mm curvature radius. The MFD and Aeff are 9.03 μm and 59.11 μm2. Moreover, the upstream and downstream bit-rates are approximately 2.38 Gbit/s-km and 3.05 Gbit/s-km.

  6. Telemedicine and rural health care applications

    Full Text Available Telemedicine has the potential to help facilitate the delivery of health services to rural areas. In the right circumstances, telemedicine may also be useful for the delivery of education and teaching programmes and the facilitation of administrative meetings. In this paper reference is made to a variety of telemedicine applications in Australia and other countries including telepaediatrics, home telehealth, critical care telemedicine for new born babies, telemedicine in developing countries, health screening via e-mail, and teleradiology. These applications represent some of the broad range of telemedicine applications possible. An overriding imperative is to focus on the clinical problem first with careful consideration given to the significant organisational changes which are associated with the introduction of a new service or alternative method of service delivery. For telemedicine to be effective it is also important that all sites involved are adequately resourced in terms of staff, equipment, telecommunications, technical support and training. In addition, there are a number of logistical factors which are important when considering the development of a telemedicine service including site selection, clinician empowerment, telemedicine management, technological requirements, user training, telemedicine evaluation, and information sharing through publication.

  7. Improved Bit Rate Control for Real-Time MPEG Watermarking

    Directory of Open Access Journals (Sweden)

    Pranata Sugiri

    2004-01-01

    Full Text Available The alteration of compressed video bitstream due to embedding of digital watermark tends to produce unpredictable video bit rate variations which may in turn lead to video playback buffer overflow/underflow or transmission bandwidth violation problems. This paper presents a novel bit rate control technique for real-time MPEG watermarking applications. In our experiments, spread spectrum watermarks are embedded in the quantized DCT domain without requantization and motion reestimation to achieve fast watermarking. The proposed bit rate control scheme evaluates the combined bit lengths of a set of multiple watermarked VLC codewords, and successively replaces watermarked VLC codewords having the largest increase in bit length with their corresponding unmarked VLC codewords until a target bit length is achieved. The proposed method offers flexibility and scalability, which are neglected by similar works reported in the literature. Experimental results show that the proposed bit rate control scheme is effective in meeting the bit rate targets and capable of improving the watermark detection robustness for different video contents compressed at different bit rates.

    Full Text Available Telemedicine has been a technological takeaway for the developed countries. Even in the developing countries, it is increasingly being viewed as a tool for improving care and enhancing access to healthcare. Countries like India where the majority of the population lives in rural areas, where healthcare facilities are inefficient and inadequate, tools like telemedicine can contribute substantially in bridging the gap between the demand and supply. "Sanjeevani"-is an integrated telemedicine application that offers a suite of high utility features as a part of an Indian telemedicine technology. Sanjeevani is based on store and forward as well as real-time models.

  10. Very low bit rate video coding of moving targets

    Garcia, Jose A.; Rodriguez-Sanchez, Rosa; Fdez-Valdivia, Joaquin; Martinez-Baena, Javier

    2006-03-01

    We propose a video coding scheme to improve moving-target detection at very low bit rate, based on two key features: energy-based quantizer formation, and optimized interquantizer and intraquantizer prioritization. Rational Embedded Wavelet Video Coding (REVIC) is a fully implemented software video codec of low complexity and without motion compensated filtering to provide additional simplicity, adaptivity, and error resilience. It is shown to be quite effective in video coding of moving targets (e.g., military vehicles) at very low bit rates, while retaining the attributes of complete embeddedness for progressive transmission and scalability by fidelity and resolution. The proposed coding technique improves the explanatory power of decoded sequences (to achieve maximum target detection versus bit-rate performance) for a video compression system. The explanatory power of compressed sequences is important in surveillance applications, where trained video analysts may utilize decoded sequences to support decision processes in strategic, operational, and tactical tasks.

  11. Low Bit Rate Motion Video Coder/Decoder For Teleconferencing

    Science.gov (United States)

    Koga, T.; Niwa, K.; Iijima, Y.; Iinuma, K.

    1987-07-01

    This paper describes motion video compression transmission for teleconferencing at a subprimary rate, i.e., at 384 kbits/s, including audio signal through the integrated services digital network (ISDN) HO channel. A subprimary rate video coder/decoder (codec), NETEC-XV, is available commercially that can operate at any bit rate (in multiples of 64 kbits/s) from 384 to 2048 kbits/s. In this paper, new algorithms are described that have been very useful in lowering the bit rate to 384 kbits/s. These algorithms are (1) separation of moving and still parts, followed by encoding of the two parts using different sets of parameters, and (2) scene change detection and its application to encoding parameter control. According to a brief subjective evaluation, the codec provides good picture quality even at a transmission bit rate of 384 kbits/s.

    "Ultra Low Bit-Rate Speech Coding" focuses on the specialized topic of speech coding at very low bit-rates of 1 Kbits/sec and less, particularly at the lower ends of this range, down to 100 bps. The authors set forth the fundamental results and trends that form the basis for such ultra low bit-rates to be viable and provide a comprehensive overview of various techniques and systems in literature to date, with particular attention to their work in the paradigm of unit-selection based segment quantization. The book is for research students, academic faculty and researchers, and industry practitioners in the areas of speech processing and speech coding.

  13. Warped Discrete Cosine Transform-Based Low Bit-Rate Block Coding Using Image Downsampling

    Directory of Open Access Journals (Sweden)

    Ertürk Sarp

    2007-01-01

    Full Text Available This paper presents warped discrete cosine transform (WDCT-based low bit-rate block coding using image downsampling. While WDCT aims to improve the performance of conventional DCT by frequency warping, the WDCT has only been applicable to high bit-rate coding applications because of the overhead required to define the parameters of the warping filter. Recently, low bit-rate block coding based on image downsampling prior to block coding followed by upsampling after the decoding process is proposed to improve the compression performance for low bit-rate block coders. This paper demonstrates that a superior performance can be achieved if WDCT is used in conjunction with image downsampling-based block coding for low bit-rate applications.

  14. Quality-on-Demand Compression of EEG Signals for Telemedicine Applications Using Neural Network Predictors

    N. Sriraam

    2011-01-01

    Full Text Available A telemedicine system using communication and information technology to deliver medical signals such as ECG, EEG for long distance medical services has become reality. In either the urgent treatment or ordinary healthcare, it is necessary to compress these signals for the efficient use of bandwidth. This paper discusses a quality on demand compression of EEG signals using neural network predictors for telemedicine applications. The objective is to obtain a greater compression gains at a low bit rate while preserving the clinical information content. A two-stage compression scheme with a predictor and an entropy encoder is used. The residue signals obtained after prediction is first thresholded using various levels of thresholds and are further quantized and then encoded using an arithmetic encoder. Three neural network models, single-layer and multi-layer perceptrons and Elman network are used and the results are compared with linear predictors such as FIR filters and AR modeling. The fidelity of the reconstructed EEG signal is assessed quantitatively using parameters such as PRD, SNR, cross correlation and power spectral density. It is found from the results that the quality of the reconstructed signal is preserved at a low PRD thereby yielding better compression results compared to results obtained using lossless scheme.

    2000-01-01

    We examined the use of telemedicine at two major medical institutions in Ghana. Doctors and administrators were surveyed to assess their knowledge of computers and familiarity with telemedicine. The use of modern telecommunications and information technology products within the health service was also examined. Thirty questionnaires were distributed to staff at the two hospitals, one urban and one rural. Twenty were returned (a response rate of 67%). Although most of the respondents were computer literate, they were less familiar with telemedicine applications. Only a minority of the respondents were participating in an information-sharing network, transmitting information by fax or telephone, or had Internet access. Financial constraint appeared to be the major barrier to establishing information-sharing networks. Other constraints were technological and organizational. The respondents expressed an interest in using telemedicine, having access to health-care databases and specific telemedicine applications such as tele-education and videoconferencing. Staff in the urban hospital were more likely to be familiar with telemedicine and more likely to have access to information technology than those in the rural hospital.

    Demiris, George

    2006-01-01

    Surveys can be used in the evaluation of telemedicine applications but they must be properly designed, consistent and accurate. The purpose of the survey and the resources available will determine the extent of testing that a survey instrument should undergo prior to its use. The validity of an instrument is the correspondence between what is being measured and what was intended to be measured. The reliability of an instrument describes the 'consistency' or 'repeatability' of the measurements made with it. Survey instruments should be designed and tested following basic principles of survey development. The actual survey administration also requires consideration, for example data collection and processing, as well as the interpretation of the findings. Surveys are of two different types. Either they are self-administered, or they are administered by interview. In the latter case, they may be administered by telephone or in a face-to-face meeting. It is important to design a survey instrument based on a detailed definition of what it intends to measure and to test it before administering it to the larger sample.

  17. A fixed/variable bit-rate data compression architecture

    Zweigle, Gregary C.; Venbrux, Jack; Yeh, Pen-Shu

    1993-01-01

    A VLSI architecture for an adaptive data compression encoder capable of sustaining fixed or variable bit-rate output has been developed. There are three modes of operation: lossless with variable bit-rate, lossy with fixed bit-rate and lossy with variable bit-rate. For lossless encoding, the implementation is identical to the USES chip designed for Landsat 7. Obtaining a fixed bit-rate is achieved with a lossy DPCM algorithm using adaptive, nonuniform scalar quantization. In lossy mode, variable bit-rate coding uses the lossless sections of the encoder for post-DPCM entropy coding. The encoder shows excellent compression performance in comparison to other current data compression techniques. No external tables or memory are required for operation.

  18. A multi-bit rate interface movement compensated multimode coder for video conferencing

    Science.gov (United States)

    1982-04-01

    This report describes a multi-bit rate video coder for DARPA video conferencing applications. The coder can operate at any preselected transmission bit rate ranging from 1.5 Mb/s to 64 kb/s. The proposed National Command Authority Teleconferencing System (NCATS) is designed to connect several conferencing sites. The system provides shared audio, video and graphic spaces. The video conferencing system communicates dynamic images of participants to different conferencing sites. The system is designed to operate under different bandwidth constraints. Under emergency situations communications bandwidth can be drastically reduced to allow only for 64 kb/s to carry out the video conferencing system. Under normal conditions larger channel capacity is available for this service. In order to accommodate the above requirements, a video codec that can operate at different transmission bit rates is needed. This allows for upgrading of picture quality when there is sufficient bandwidth and a graceful reduction of picture quality under severe bandwidth limitations. The NTSC colour video signal sampled at 14.3 MHz (4 times the colour subcarrier frequency) and uniformly quantized to 8 bits per picture element, requires a transmission bit rate of 114 Mb/s. Such a high bit rate is economically prohibitive especially for video conferencing applications. In order to reduce the transmission bit rate, redundant information in the signal has to be removed and the specific video conferencing environment has to be exploited.

    Riva, G; Gamberini, L

    2000-01-01

    This paper surveys the state of the art in telemedicine applications of virtual environments (VEs) and related technologies for health care. The possible use of VEs as telemedicine tool has attracted much interest in medicine. Actually this technology is commonly used in remote or augmented surgery, and surgical training, which are critically dependent upon eye-hand coordination. Recently, however, different researchers have tried to use VEs in anatomic learning and for the assessment and rehabilitation in neuro-psychology. To date, such applications have improved the quality of health care, and later they will lead to substantial cost savings. Tools that respond to the needs of present VE systems are being refined or developed. However, the possible use of VEs in telemedicine is not linked to the solution of technical problems only. In fact telemedicine is not simply a technology but a complex process whose successful exploitation needs significant attention to ergonomics, human factors and organizational changes in the structure of the relevant health service.

    Telemedicine and teleconsultation are the application and development of the telecommunication networks. Health experts can solve problems by using the electronic and communication technologies without distance limitation. In this study, we try to develop the telemedicine and teleconsultation system between local site and consulting expert site. Two applications of this system in clinical medicine are discussed. The system at each site has a workstation including a cable modem or ADSL connection, a monitor, a web camera, speakers, a microphone for communication, and NetMeeting application software. The first application in this study is to develop a school-based intervention program by using this system for high-risk school-age children in one of the earthquake-struck areas. The preliminary result of this study is that the telemedicine and teleconsultation system is more effective than traditional consultation and supervision. Moreover, we can apply this system in training local volunteers, educators, and welfare workers. Meanwhile, we can save lots of cost and time since we don't need to travel between the local site and the expert site. In the end of this study, the second application of this system in SARS case treatment was also discussed.

    Full Text Available Telemedicine scenarios include today in-hospital care management, remote teleconsulting, collaborative diagnosis and emergency situations handling. Different types of information need to be accessed by means of etherogeneous client devices in different communication environments in order to enable high quality continuous sanitary assistance delivery wherever and whenever needed. In this paper, a Web-based telemedicine architecture based on Java, XML and XSL technologies is presented. By providing dynamic content delivery services and Java based client applications for medical data consultation and modification, the system enables effective access to an Electronic Patient Record based standard database by means of any device equipped with a Web browser, such as traditional Personal Computers and workstation as well as modern Personal Digital Assistants. The effectiveness of the proposed architecture has been evaluated in different scenarios, experiencing fixed and mobile clinical data transmissions over Local Area Networks, wireless LANs and wide coverage telecommunication network including GSM and GPRS.

  2. Video Synchronization With Bit-Rate Signals and Correntropy Function

    2017-09-01

    Full Text Available We propose an approach for the synchronization of video streams using correntropy. Essentially, the time offset is calculated on the basis of the instantaneous transfer rates of the video streams that are extracted in the form of a univariate signal known as variable bit-rate (VBR. The state-of-the-art approach uses a window segmentation strategy that is based on consensual zero-mean normalized cross-correlation (ZNCC. This strategy has an elevated computational complexity, making its application to synchronizing online data streaming difficult. Hence, our proposal uses a different window strategy that, together with the correntropy function, allows the synchronization to be performed for online applications. This provides equivalent synchronization scores with a rapid offset determination as the streams come into the system. The efficiency of our approach has been verified through experiments that demonstrate its viability with values that are as precise as those obtained by ZNCC. The proposed approach scored 81 % in time reference classification against the equivalent 81 % of the state-of-the-art approach, requiring much less computational power.

    Telemedicine includes all medical activities involved in diagnosis, therapeutics or social medicine undertaken by an electronic transfer medium. This technique requires the transmission of visual and acoustic information over long distances and does not require the specialist to be personally present at the requested consultation. In the last few years, the digital data transmission, e.g., ISDN (ISDN (Integrated Service Digital Network), has become available and has facilitated the use of telecommunication. Recently, the real-time transmission of acoustic and visual signals will be improved by use of asynchronous transfer mode (ATM). Advanced telecommunication applications in minimally invasive ENT surgery are experimental in most cases. We can distinguish three different telesurgical developments: surgical teleconsultation, surgical teleassistance, and surgical telemanipulation. The different applications and transmission media are explained and discussed.

    Full Text Available Lilian Beijer,1 Toni Rietveld2 1Sint Maartenskliniek, 2Centre of Language Studies, Radboud University of Nijmegen, Nijmegen, The Netherlands Abstract: In this time of an aging population in the Western world and a concomitant need for cost reduction, there is an obvious need for innovative health care delivery. One of the consequences is that a growing number of telemedicine applications are emerging in different health care domains. Also in the area of speech-language (SL disorders, particularly neurogenic disorders, telemedicine is rapidly gaining interest. In this paper, we place applications for neurogenic SL disorders in a telemedicine taxonomy in order to establish common features along the dimensions of functionality, application, and technology, and their components. Thus, we aim at identifying common features in a wide variety of telemedicine applications and to establish common interests of stakeholders in health care for classified groups of telemedicine applications. This may facilitate decision-making with regard to expansion of innovative products, and give directions to measures needed for upscaling and structural embedding of feasible and effective SL telemedicine applications in health care. Common interests of stakeholders in health care, established using telemedicine taxonomy, is a key factor in decision-making with regard to which telemedicine applications should be given priority for genuine utilization. Priorities of health care institutions, patients, and reimbursement companies are also leading for researchers aiming at solid scientific evidence for the beneficial effects of target applications. That is, although research results tend to indicate the potential of telemedicine in the area of SL pathology, the alleged benefits of most applications have not been confirmed according to the accepted standards for clinical outcome testing as yet.

In spite of the ISS international cooperation transparency space research programs require to follow the biomedicine ethics and provide confidentiality of the special medical information exchange. That can be achieved in the telemedicine support system built on the network principle. Presently we have all technical facilities needed to create such a system. In Russia activities on space telemedicicine support improvement are carried out by the State Scientific Center of the Russian Federation - Institute for Biomedical Problems of the Russian Academy of Sciences, Mission Control Center of the Russian Aviation and Space Agency, Space Biomedical Center for Training and Research and Yu. Gagarin Cosmonaut Training Center. Communications development and next generation Internet systems creation almost eliminate differences in the types of information technologies implementation both in the earth-based and near-earth space conditions. In prospect of the information community creation the telecommunication system of the near-earth space objects and its telemedicine element will become a natural part of the Earth unified information field that will open unlimited perspectives for flight support system improvement and space biomedical research conducting. Russia has unique data of numerous investigations on simulation of long, up to a year, effects of space flight factors on the human body. The sphere of situations studied by space medicine specialists embraced orbit manned space flights of the escalating duration (438 days in 1995). However a number of biomedical problems related to space flights didn't face optimal solutions. It's evident that during a space flight to Mars biomedical problems will be much more difficult in comparison with those of the orbit flights of the same duration. The summed up factors of such flights specify a level of the total medical risk that require assessment and application of

    Advanced technology has increased the use of telemedicine and Information Technology (IT) in treating or rehabilitating diseases. An increased use of technology increases the importance of the ethical issues involved. The need for keeping patients' information confidential and secure, controlling a number of therapists' inefficiency as well as raising the quality of healthcare services necessitates adequate heed to ethical issues in telemedicine provision. The goal of this review is gathering all articles that are published through 5 years until now (2012-2017) for detecting ethical issues for providing telemedicine services and Information technology. The reason of this time is improvement of telemedicine and technology through these years. This article is important for clinical practice and also to world, because of knowing ethical issues in telemedicine and technology are always important factors for physician and health providers. the required data in this research were derived from published electronic sources and credible academic articles published in such databases as PubMed, Scopus and Science Direct. The following key words were searched for in separation and combination: tele-health, telemedicine, ethical issues in telemedicine. A total of 503 articles were found. After excluding the duplicates (n= 93), the titles and abstracts of 410 articles were skimmed according to the inclusion criteria. Finally, 64 articles remained. They were reviewed in full text and 36 articles were excluded. At the end, 28 articles were chosen which met our eligibility criteria and were included in this study. Ethics has been of a great significance in IT and telemedicine especially the Internet since there are more chances provided for accessing information. It is, however, accompanied by a threat to patients' personal information. Therefore, suggestions are made to investigate ethics in technology, to offer standards and guidelines to therapists.

    Gilchrist, N. H. C.

    At the beginning of 1990, BBC Research Department tested four experimental high-quality low bit-rate audio codecs which were under development as part of the Eureka 147 Digital Audio Broadcasting project. The work involved preliminary listening tests to identify critical test material, followed by formal subjective tests to determine audio quality and error performance. The listeners could detect some loss of audio quality with all of the codecs using the most critical material. There were also indications that one of the codecs did not always reproduce the phantom sound sources in their correct position.

    1987-06-01

    In view of the 56 KBPS digital switched network services and the ISDN, low bit rate codecs for providing real time full motion color video are under various stages of development. Some companies have already brought the codecs into the market. They are being used by industry and some Federal Agencies for video teleconferencing. In general, these codecs have various features such as multiplexing audio and data, high resolution graphics, encryption, error detection and correction, self diagnostics, freezeframe, split video, text overlay etc. To transmit the original color video on a 56 KBPS network requires bit rate reduction of the order of 1400:1. Such a large scale bandwidth compression can be realized only by implementing a number of sophisticated,digital signal processing techniques. This paper provides an overview of such techniques and outlines the newer concepts that are being investigated. Before resorting to the data compression techniques, various preprocessing operations such as noise filtering, composite-component transformation and horizontal and vertical blanking interval removal are to be implemented. Invariably spatio-temporal subsampling is achieved by appropriate filtering. Transform and/or prediction coupled with motion estimation and strengthened by adaptive features are some of the tools in the arsenal of the data reduction methods. Other essential blocks in the system are quantizer, bit allocation, buffer, multiplexer, channel coding etc.

    Remote monitoring of crew, spacecraft, and environmental health has always been an integral part of the National Aeronautics and Space Administration's (NASA's) operations. Crew safety and mission success face a number of challenges in outerspace, including physiological adaptations to microgravity, radiation exposure, extreme temperatures and vacuum, and psychosocial reactions to space flight. The NASA effort to monitor and maintain crew health, system performance, and environmental integrity in space flight is a sophisticated and coordinated program of telemedicine combining cutting-edge engineering with medical expertise. As missions have increased in complexity, NASA telemedicine capabilities have grown apace, underlying its role in the field. At the same time, the terrestrial validation of telemedicine technologies to bring healthcare to remote locations provides feedback, improvement, and enhancement of the space program. As NASA progresses in its space exploration program, astronauts will join missions lasting months, even years, that take them millions of miles from home. These long-duration missions necessitate further technological breakthroughs in tele-operations and autonomous technology. Earth-based monitoring will no longer be real-time, requiring telemedicine capabilities to advance with future explorers as they travel deeper into space. The International Space Station will serve as a testbed for the telemedicine technologies to enable future missions as well as improve the quality of healthcare delivery on Earth.

    Telemedicine is traditionally associated with the use of very expensive and bulky telecommunications equipment along with substantial bandwidth requirements (128 kilobytes per second [kbps] or greater). Telementoring is an educational technique that involves real-time guidance of a less experienced physician through a procedure in which he or she has limited experience. This technique has been especially dependent on the aforementioned requirements. Traditionally, telemedicine and telementoring have been restricted to technically sophisticated sites. The telemedicine applications through the existing telecommunication infrastructure has not been possible for underdeveloped parts of the world. Telemedicine and telementoring were applied using low-bandwidth mobile telemedicine applications to support a mobile surgery program in rural Ecuador run by the Cinterandes Foundation and headed by Edgar Rodas, MD. A mobile operating room traveled to a remote region of Ecuador. Using a laptop computer equipped with telemedicine software, a videoconferencing system, and a digital camera, surgical patients were evaluated and operative decisions were made over low-bandwidth telephone lines. Similarly, surgeons in the mobile unit in Ecuador were telementored by an experienced surgeon located thousands of miles away at Yale University School of Medicine. Five preoperative evaluations were conducted from Sucua to Cuenca, Ecuador, with excellent clinical correlation. Additionally, a laparoscopic cholecystectomy was successfully telementored from the department of surgery at Yale University School of Medicine to the mobile surgery unit in Ecuador. The telementored surgery was performed using a telephone line with a baud rate of 12 kbps. Mobile, low-bandwidth telemedicine applications used in the proper technical and clinical algorithms can be very effective in supporting remote health care delivery efforts. Advantages of such applications include increased cost-effectiveness by

    Telemedicine as a means of remote patient-physician interaction is growing and virtual consultations with sleep specialists are feasible. Potential benefits of telemedicine include improved access to health care, reduced waiting time for appointments, and increased adherence to treatment plans. Telematic communications and new information technologies could also be useful to establish diagnostic and therapeutic strategies. It is important to install cost-efficient technologies for an initial simple diagnosis, rapid treatment initiation and for long-term monitoring of treatment adherence and compliance. Diagnostic telemedicine applications include telemonitored polysomnography, long-term polygraphic monitoring, and remote continuous positive airway pressure titration and monitoring.

  18. Efficient Region-of-Interest Scalable Video Coding with Adaptive Bit-Rate Control

    Directory of Open Access Journals (Sweden)

    Dan Grois

    2013-01-01

    Full Text Available This work relates to the regions-of-interest (ROI coding that is a desirable feature in future applications based on the scalable video coding, which is an extension of the H.264/MPEG-4 AVC standard. Due to the dramatic technological progress, there is a plurality of heterogeneous devices, which can be used for viewing a variety of video content. Devices such as smartphones and tablets are mostly resource-limited devices, which make it difficult to display high-quality content. Usually, the displayed video content contains one or more ROI(s, which should be adaptively selected from the preencoded scalable video bitstream. Thus, an efficient scalable ROI video coding scheme is proposed in this work, thereby enabling the extraction of the desired regions-of-interest and the adaptive setting of the desirable ROI location, size, and resolution. In addition, an adaptive bit-rate control is provided for the region-of-interest scalable video coding. The performance of the presented techniques is demonstrated and compared with the joint scalable video model reference software (JSVM 9.19, thereby showing significant bit-rate savings as a tradeoff for the relatively low PSNR degradation.

  19. A low bit rate FSK technique for SCPC satellite communication systems

    Science.gov (United States)

    Shpilka, Vladimir

    This paper concerns itself with the description and analysis of an application of FSK (frequency shift keying) communication system method, with which it is possible to eliminate the degrading effects of ground station as well as satellite contributed phase noise on very low bit rate communication systems. Typical transmitter and receiver block diagrams are provided. In situations where speed of information transmission is not of the greatest importance, but availability of DC power for the radio frequency transmitter is at premium, the above mentioned FSK technique would yield very low power communication systems, that could be used with the proposed MSAT satellite. Potential applications could include the development of handheld pocket sized messaging communicators and solar powered environmental data collection platforms. This class of earth terminals would operate at L-Band and would fall into the category of mobile earth terminals within the context of the MSAT system.

    Lin, C F; Hung, S I; Chiang, I H

    2010-10-01

    In this paper, an 802.11 n transmission scheme is proposed for wireless telemedicine applications. IEEE 802.11n standards, a power assignment strategy, space-time block coding (STBC), and an object composition Petri net (OCPN) model are adopted. With the proposed wireless system, G.729 audio bit streams, Joint Photographic Experts Group 2000 (JPEG 2000) clinical images, and Moving Picture Experts Group 4 (MPEG-4) video bit streams achieve a transmission bit error rate (BER) of 10-7, 10-4, and 103 simultaneously. The proposed system meets the requirements prescribed for wireless telemedicine applications. An essential feature of this proposed transmission scheme is that clinical information that requires a high quality of service (QoS) is transmitted at a high power transmission rate with significant error protection. For maximizing resource utilization and minimizing the total transmission power, STBC and adaptive modulation techniques are used in the proposed 802.11 n wireless telemedicine system. Further, low power, direct mapping (DM), low-error protection scheme, and high-level modulation are adopted for messages that can tolerate a high BER. With the proposed transmission scheme, the required reliability of communication can be achieved. Our simulation results have shown that the proposed 802.11 n transmission scheme can be used for developing effective wireless telemedicine systems.

  1. Digital echocardiography and telemedicine applications in pediatric cardiology.

    Science.gov (United States)

    Sable, Craig

    2002-01-01

    Digital echocardiography offers several advantages over videotape, including easy review, comparison, storage, postprocessing, and sharing of studies, quantitative analysis, and superior resolution. Newer echocardiography systems can write digital data to computer hardware, whereas older systems require digitization of analog data. Clinical and digital data compression is required to reduce study size. Clinical compression has been validated in several adult studies and one pediatric study. JPEG and MPEG digital compression ratios of 26:1 and 200:1, respectively, approximate S-videotape quality. JPEG is the DICOM 3.0 standard and is ideal for short loops, serial comparisons, and quantitative analysis. MPEG (the motion picture standard) lends itself to digitization of video streams and may be more attractive to pediatric cardiologists. Options for data storage and transfer range from limited local review to multiple offline review stations linked by a wide-area network. Telemedicine expands the capabilities of digital echocardiography in a "store and forward" or "real-time" format. Real-time neonatal telecardiology is accurate, impacts patient care, is cost-effective, and does not increase utilization. Cost, increased reliance on sonographers' skills, lack of accepted standards, and legal, licensure, and billing issues are obstacles to widespread acceptance of digital echocardiography and telemedicine.

    1994-01-01

    The technology to reliably transmit high-resolution visual imagery over short to medium distances in real time has led to the serious considerations of the use of telemedicine, telepresence, and telerobotics in the delivery of health care. These concepts may involve, and evolve toward: consultation from remote expert teaching centers; diagnosis; triage; real-time remote advice to the surgeon; and real-time remote surgical instrument manipulation (telerobotics with virtual reality). Further extrapolation leads to teledesign and telereplication of spare surgical parts through quantitative teleimaging of 3-D surfaces tied to CAD/CAM devices and an artificially intelligent archival data base of 'normal' shapes. The ability to generate 'topogrames' or 3-D surface numerical tables of coordinate values capable of creating computer-generated virtual holographic-like displays, machine part replication, and statistical diagnostic shape assessment is critical to the progression of telemedicine. Any virtual reality simulation will remain in 'video-game' realm until realistic dimensional and spatial relational inputs from real measurements in vivo during surgeries are added to an ever-growing statistical data archive. The challenges of managing and interpreting this 3-D data base, which would include radiographic and surface quantitative data, are considerable. As technology drives toward dynamic and continuous 3-D surface measurements, presenting millions of X, Y, Z data points per second of flexing, stretching, moving human organs, the knowledge base and interpretive capabilities of 'brilliant robots' to work as a surgeon's tireless assistants becomes imaginable. The brilliant robot would 'see' what the surgeon sees--and more, for the robot could quantify its 3-D sensing and would 'see' in a wider spectral range than humans, and could zoom its 'eyes' from the macro world to long-distance microscopy. Unerring robot hands could rapidly perform machine-aided suturing with

    We have experimentally demonstrated two novel pulse position modulation techniques, namely Double Pulse Position Modulation (2-PPM) and Differential Pulse Position Modulation (DPPM) in Time-Wavelength OCDMA systems that will operate at a higher bit rate compared to traditional OOK-OCDMA systems with the same bandwidth. With 2-PPM technique, the number of active users will be more than DPPM while their bit rate is almost the same. Both techniques provide variable quality of service in OCDMA networks.

    To review current literature on neurology telemedicine and to discuss its application to patient care, neurology practice, military medicine, and current federal policy. Review of practice models and published literature on primary studies of the efficacy of neurology telemedicine. Teleneurology is of greatest benefit to populations with restricted access to general and subspecialty neurologic care in rural areas, those with limited mobility, and those deployed by the military. Through the use of real-time audio-visual interaction, imaging, and store-and-forward systems, a greater proportion of neurologists are able to meet the demand for specialty care in underserved communities, decrease the response time for acute stroke assessment, and expand the collaboration between primary care physicians, neurologists, and other disciplines. The American Stroke Association has developed a defined policy on teleneurology, and the American Academy of Neurology and federal health care policy are beginning to follow suit. Teleneurology is an effective tool for the rapid evaluation of patients in remote locations requiring neurologic care. These underserved locations include geographically isolated rural areas as well as urban cores with insufficient available neurology specialists. With this technology, neurologists will be better able to meet the burgeoning demand for access to neurologic care in an era of declining availability. An increase in physician awareness and support at the federal and state level is necessary to facilitate expansion of telemedicine into further areas of neurology.

    Reliable identification is essential in e-health and telemedicine applications. This necessitates a secure and trustworthy method of communication and collaboration between parties, which depends on common acceptance. This in turn is related to privacy and ethical matters. Different technologies, including biometrics and RFID, allow high levels of security and safety in identifying both human beings and goods. However, the diffusion of standards relating to identity management in e-health is far from satisfactory. In order to support standardization in e-health, the European Commission funded the BioHealth project. This project has proved to be useful in promoting standards and creating awareness among the stakeholders.

  10. A Novel Rate Control Scheme for Constant Bit Rate Video Streaming

    Directory of Open Access Journals (Sweden)

    Venkata Phani Kumar M

    2015-08-01

    Full Text Available In this paper, a novel rate control mechanism is proposed for constant bit rate video streaming. The initial quantization parameter used for encoding a video sequence is determined using the average spatio-temporal complexity of the sequence, its resolution and the target bit rate. Simple linear estimation models are then used to predict the number of bits that would be necessary to encode a frame for a given complexity and quantization parameter. The experimental results demonstrate that our proposed rate control mechanism significantly outperforms the existing rate control scheme in the Joint Model (JM reference software in terms of Peak Signal to Noise Ratio (PSNR and consistent perceptual visual quality while achieving the target bit rate. Furthermore, the proposed scheme is validated through implementation on a miniature test-bed.

  11. Highly accurate moving object detection in variable bit rate video-based traffic monitoring systems.

    Huang, Shih-Chia; Chen, Bo-Hao

    2013-12-01

    Automated motion detection, which segments moving objects from video streams, is the key technology of intelligent transportation systems for traffic management. Traffic surveillance systems use video communication over real-world networks with limited bandwidth, which frequently suffers because of either network congestion or unstable bandwidth. Evidence supporting these problems abounds in publications about wireless video communication. Thus, to effectively perform the arduous task of motion detection over a network with unstable bandwidth, a process by which bit-rate is allocated to match the available network bandwidth is necessitated. This process is accomplished by the rate control scheme. This paper presents a new motion detection approach that is based on the cerebellar-model-articulation-controller (CMAC) through artificial neural networks to completely and accurately detect moving objects in both high and low bit-rate video streams. The proposed approach is consisted of a probabilistic background generation (PBG) module and a moving object detection (MOD) module. To ensure that the properties of variable bit-rate video streams are accommodated, the proposed PBG module effectively produces a probabilistic background model through an unsupervised learning process over variable bit-rate video streams. Next, the MOD module, which is based on the CMAC network, completely and accurately detects moving objects in both low and high bit-rate video streams by implementing two procedures: 1) a block selection procedure and 2) an object detection procedure. The detection results show that our proposed approach is capable of performing with higher efficacy when compared with the results produced by other state-of-the-art approaches in variable bit-rate video streams over real-world limited bandwidth networks. Both qualitative and quantitative evaluations support this claim; for instance, the proposed approach achieves Similarity and F1 accuracy rates that are 76

    2010-06-01

    Full Text Available This paper presents a channel-adaptive video streaming scheme which adjusts video bit rate according to channel conditions and transmits video through a hybrid RF/free space optical (FSO laser communication system. The design criteria of the FSO link for video transmission to 2.9 km distance have been given and adaptive bit rate video streaming according to the varying channel state over this link has been studied. It has been shown that the proposed structure is suitable for uninterrupted transmission of videos over the hybrid wireless network with reduced packet delays and losses even when the received power is decreased due to weather conditions.

    Optical nanoantennas provide a promising pathway toward advanced manipulation of light waves, such as directional scattering, polarization conversion, and fluorescence enhancement. Although these functionalities were mainly studied for nanoantennas in free space or on homogeneous substrates, their integration with optical waveguides offers an important "wired" connection to other functional optical components. Taking advantage of the nanoantenna's versatility and unrivaled compactness, their imprinting onto optical waveguides would enable a marked enhancement of design freedom and integration density for optical on-chip devices. Several examples of this concept have been demonstrated recently. However, the important question of whether nanoantennas can fulfill functionalities for high-bit rate signal transmission without degradation, which is the core purpose of many integrated optical applications, has not yet been experimentally investigated. We introduce and investigate directional, polarization-selective, and mode-selective on-chip nanoantennas integrated with a silicon rib waveguide. We demonstrate that these nanoantennas can separate optical signals with different polarizations by coupling the different polarizations of light vertically to different waveguide modes propagating into opposite directions. As the central result of this work, we show the suitability of this concept for the control of optical signals with ASK (amplitude-shift keying) NRZ (nonreturn to zero) modulation [10 Gigabit/s (Gb/s)] without significant bit error rate impairments. Our results demonstrate that waveguide-integrated nanoantennas have the potential to be used as ultra-compact polarization-demultiplexing on-chip devices for high-bit rate telecommunication applications.

    Advances in technology have revolutionized the medical field and changed the way healthcare is delivered. Unmanned aerial vehicles (UAVs) are the next wave of technological advancements that have the potential to make a huge splash in clinical medicine. UAVs, originally developed for military use, are making their way into the public and private sector. Because they can be flown autonomously and can reach almost any geographical location, the significance of UAVs are becoming increasingly apparent in the medical field. We conducted a comprehensive review of the English language literature via the PubMed and Google Scholar databases using search terms "unmanned aerial vehicles," "UAVs," and "drone." Preference was given to clinical trials and review articles that addressed the keywords and clinical medicine. Potential applications of UAVs in medicine are broad. Based on articles identified, we grouped UAV application in medicine into three categories: (1) Prehospital Emergency Care; (2) Expediting Laboratory Diagnostic Testing; and (3) Surveillance. Currently, UAVs have been shown to deliver vaccines, automated external defibrillators, and hematological products. In addition, they are also being studied in the identification of mosquito habitats as well as drowning victims at beaches as a public health surveillance modality. These preliminary studies shine light on the possibility that UAVs may help to increase access to healthcare for patients who may be otherwise restricted from proper care due to cost, distance, or infrastructure. As with any emerging technology and due to the highly regulated healthcare environment, the safety and effectiveness of this technology need to be thoroughly discussed. Despite the many questions that need to be answered, the application of drones in medicine appears to be promising and can both increase the quality and accessibility of healthcare.

    Telemedicine generally refers to the use of communications and information technologies for the delivery of health care. owever, telemedicine is not merely a simple combination of health care and technology. The researchers propose a systematic approach for assessing needs of telemedicine customers, called critical-to-quality (CTQ) in Six Sigma, with a purpose of continuous quality improvement. The combination approach using DFSS (Design for Six Sigma) and SERVQUAL (Service Quality Framework) was applied to define the critical quality attributes of telemedicine service management and to match them with the current telemedicine process. With a step-by-step procedure, telemedicine service process was reviewed and all the important CTQ candidates identified via a case study. The findings suggest that nurses need further understanding and research methods that will improve and manage the quality of health care service in various medical fields.

  19. A Robust Automated Cataract Detection Algorithm Using Diagnostic Opinion Based Parameter Thresholding for Telemedicine Application

    Directory of Open Access Journals (Sweden)

    Shashwat Pathak

    2016-09-01

    Full Text Available This paper proposes and evaluates an algorithm to automatically detect the cataracts from color images in adult human subjects. Currently, methods available for cataract detection are based on the use of either fundus camera or Digital Single-Lens Reflex (DSLR camera; both are very expensive. The main motive behind this work is to develop an inexpensive, robust and convenient algorithm which in conjugation with suitable devices will be able to diagnose the presence of cataract from the true color images of an eye. An algorithm is proposed for cataract screening based on texture features: uniformity, intensity and standard deviation. These features are first computed and mapped with diagnostic opinion by the eye expert to define the basic threshold of screening system and later tested on real subjects in an eye clinic. Finally, a tele-ophthamology model using our proposed system has been suggested, which confirms the telemedicine application of the proposed system.

    Full Text Available 3-Dimensional (3D video adaptation decision taking is an open field in which not many researchers have carried out investigations yet compared to 3D video display, coding, etc. Moreover, utilizing ambient illumination as an environmental context for 3D video adaptation decision taking has particularly not been studied in literature to date. In this paper, a user perception model, which is based on determining perception characteristics of a user for a 3D video content viewed under a particular ambient illumination condition, is proposed. Using the proposed model, a 3D video bit rate adaptation decision taking technique is developed to determine the adapted bit rate for the 3D video content to maintain 3D video quality perception by considering the ambient illumination condition changes. Experimental results demonstrate that the proposed technique is capable of exploiting the changes in ambient illumination level to use network resources more efficiently without sacrificing the 3D video quality perception.

At the encoder side, the downsampling mode and quantization mode of each 16×16 macroblock are determined adaptively using the ratio distortion optimization method, then the downsampled macroblocks are compressed by the standard JPEG. At the decoder side, the sparse representation-based SR algorithm is applied to recover full resolution macroblocks from decoded blocks. The experimental results show that the proposed framework outperforms the standard JPEG and the state-of-the-art downsampling-based compression methods in terms of both subjective and objective comparisons. Specifically, the peak signal-to-noise ratio gain of the proposed framework over JPEG reaches up to 2 to 4 dB at low bit rates, and the critical bit rate to JPEG is raised to about 2.3 bits per pixel. Moreover, the proposed framework can be extended to other block-based compression schemes.

    Intra prediction process of H.264 video coding standard used to code first frame i.e. Intra frame of video to obtain good coding efficiency compare to previous video coding standard series. More benefit of intra frame coding is to reduce spatial pixel redundancy with in current frame, reduces computational complexity and provides better rate distortion performance. To code Intra frame it use existing process Rate Distortion Optimization (RDO) method. This method increases computational complexity, increases in bit rate and reduces picture quality so it is difficult to implement in real time applications, so the many researcher has been developed fast mode decision algorithm for coding of intra frame. The previous work carried on Intra frame coding in H.264 standard using fast decision mode intra prediction algorithm based on different techniques was achieved increased in bit rate, degradation of picture quality(PSNR) for different quantization parameters. Many previous approaches of fast mode decision algorithms on intra frame coding achieved only reduction of computational complexity or it save encoding time and limitation was increase in bit rate with loss of quality of picture. In order to avoid increase in bit rate and loss of picture quality a better approach was developed. In this paper developed a better approach i.e. Gaussian pulse for Intra frame coding using diagonal down left intra prediction mode to achieve higher coding efficiency in terms of PSNR and bitrate. In proposed method Gaussian pulse is multiplied with each 4x4 frequency domain coefficients of 4x4 sub macro block of macro block of current frame before quantization process. Multiplication of Gaussian pulse for each 4x4 integer transformed coefficients at macro block levels scales the information of the coefficients in a reversible manner. The resulting signal would turn abstract. Frequency samples are abstract in a known and controllable manner without intermixing of coefficients, it avoids

    A phase shift key (PSK) to BiO-L demodulator which uses standard digital integrated circuits is discussed. The demodulator produces NRZ-L, bit clock, and BiO-L outputs from digital PSK input signals for which the carrier is a 2 to the Nth multiple of the bit rate. Various bit and carrier rates which are accommodated by changing various component values within the demodulator are described. The use of the unit for sinusoidal inputs as well as digital inputs is discussed.

    The authors have an in-kind grant from NASA to investigate the application of the Advanced Communications Technology Satellite (ACTS) to teleradiology and telemedicine using the JPL developed ACTS Mobile Terminal (AMT) uplink. This experiment involves the transmission of medical imagery (CT, MR, CR, US and digitized radiographs including mammograms), between the ACTS/AMT and the University of Washington. This is accomplished by locating the AMT experiment van in various locations throughout Washington state, Idaho, Montana, Oregon and Hawaii. The medical images are transmitted from the ACTS to the downlink at the NASA Lewis Research Center (LeRC) in Cleveland, Ohio, consisting of AMT equipment and the high burst rate-link evaluation terminal (HBR-LET). These images are then routed from LeRC to the University of Washington School of Medicine (UWSoM) through the Internet and public switched Integrated Serviced Digital Network (ISDN). Once images arrive in the UW Radiology Department, they are reviewed using both video monitor softcopy and laser-printed hardcopy. Compressed video teleconferencing and transmission of real-time ultrasound video between the AMT van and the UWSoM are also tested. Image quality comparisons are made using both subjective diagnostic criteria and quantitative engineering analysis. Evaluation is performed during various weather conditions (including rain to assess rain fade compensation algorithms). Compression techniques also are tested to evaluate their effects on image quality, allowing further evaluation of portable teleradiology/telemedicine at lower data rates and providing useful information for additional applications (e.g., smaller remote units, shipboard, emergency disaster, etc.). The medical images received at the UWSoM over the ACTS are directly evaluated against the original digital images. The project demonstrates that a portable satellite-land connection can provide subspecialty consultation and education for rural and remote

    One of the applications of modern technology in telemedicine is video conferencing. An alternative to traveling to attend a conference or meeting, video conferencing is becoming increasingly popular among hospitals. By using this technology, doctors can help patients who are unable to physically visit hospitals. Video conferencing particularly benefits patients from rural areas, where good doctors are not always available. Telemedicine has proven to be a blessing to patients who have no access to the best treatment. A telemedicine system consists of customized hardware and software at two locations, namely, at the patient's and the doctor's end. In such cases, the video streams of the conferencing parties may contain highly sensitive information. Thus, real-time data security is one of the most important requirements when designing video conferencing systems. This study proposes a secure framework for video conferencing systems and a complete management solution for secure video conferencing groups. Java Media Framework Application Programming Interface classes are used to design and test the proposed secure framework. Real-time Transport Protocol over User Datagram Protocol is used to transmit the encrypted audio and video streams, and RSA and AES algorithms are used to provide the required security services. Results show that the encryption algorithm insignificantly increases the video conferencing computation time.

    2004-12-01

    Better care for patients and improved health care depends on the availability of good information which is accessible when and where it is needed. The development of technology, more specifically the Internet, has expanded the means whereby information can be acquired and transmitted over large distances enabling the concept of telemedicine to become a reality. Telemedicine, defined as the practise of medicine at a distance, encompasses diagnosis, education and treatment. It is a technology that many thought would expand rapidly and change the face of medicine. However, this has not happened and during the last decade although certain telemedicine applications, such as video-consulting and teleradiology, have matured to become essential health care services in some countries, others, such as telepathology, remain the subject of intensive research effort. Telemedicine can be used in almost any medical specialty although the specialties best suited are those with a high visual component. Wound healing and wound management is thus a prime candidate for telemedicine. Development of a suitable telemedical system in this field could have a significant effect on wound care in the community, tertiary referral patterns and hospital admission rates.

    2001-08-01

    Phoniatrics and Paedaudiology investigate and treat disorders of communication more than other medical specialties and are indicated by a distinctive interdisciplinary character. The methods of diagnosis and therapy are concentrated on a few specialists and produce a large quantity of multi-media data from daily clinical practice and research. For the cooperation between the specialists of these and neighboring branches and to reduce the costs for a second opinion these data must be available anywhere and any time using modern telecommunication and information technologies. Following applications for a bi- or multidirectional data transmission are possible: Teleconsulting (second opinion of a far located specialist). Teleteaching (use of different data sources for education) and Teleroboting (remote control of medical equipment). Data sources can be: speaking and singing voice, sound, pictures (X-ray, CT, MR, ultrasound, voice range profile, audiogramm), video signals (stroboscopy, cinematography, intraoperative pictures) and written information (computer presentations) in all combinations. The transmission can be carried out synchronously or asynchronously, i.e. at the time for their generation or independent of this. This paper discusses the basics and the advantages and disadvantages of the available technologies and compares it for phoniatric/paedaudiologic applications in an experimental transmission. Use of the different technologies should be carried out depending upon the required quality, the availability and the costs considering medico-legal aspects. Relatively cheap and always available technologies are suitable for many applications in Phoniatrics and Paedaudiology. High costs for acquisition of the equipments could lowered by a common use of different medical branches. Expensive procedures with excellent communication quality are confined to special applications at the moment. Telemedicine can optimize quality and extend of the medical care and

    Full Text Available In telemedicine, where the convergence of different types of medical treatment occurs, it is very important to establish credibility regarding the mutual communication between patients and medical workers by acquiring and sharing more accurate data. For rehabilitation treatment in particular, where motion data are required, auxiliary equipment such as a Kinect sensor is being more widely used. This study proposes a methodology for improving the motion recognition rate by compensating the noise from a Kinect sensor using a 3D autoregressive model. Moreover, this study investigates the methods applied for vitalizing the area of telemedicine under this particular trend.

  13. Influence of transmission bit rate on performance of optical fibre communication systems with direct modulation of laser diodes

    International Nuclear Information System (INIS)

    Ahmed, Moustafa F

    2009-01-01

    This paper reports on the influence of the transmission bit rate on the performance of optical fibre communication systems employing laser diodes subjected to high-speed direct modulation. The performance is evaluated in terms of the bit error rate (BER) and power penalty associated with increasing the transmission bit rate while keeping the transmission distance. The study is based on numerical analysis of the stochastic rate equations of the laser diode and takes into account noise mechanisms in the receiver. Correlation between BER and the Q-parameter of the received signal is presented. The relative contributions of the transmitter noise and the circuit and shot noises of the receiver to BER are quantified as functions of the transmission bit rate. The results show that the power penalty at BER = 10 -9 required to keep the transmission distance increases moderately with the increase in the bit rate near 1 Gbps and at high bias currents. In this regime, the shot noise is the main contributor to BER. At higher bit rates and lower bias currents, the power penalty increases remarkably, which comes mainly from laser noise induced by the pseudorandom bit-pattern effect.

    Full Text Available The escalating physiological, psychological, social and financial burdens of wounds and wound care on patients, families and society demand the immediate attention of the health care sector. Many forces are affecting the changes in health care provision for patients with chronic wounds, including managed care, the limited number of wound care therapists, an increasingly ageing and disabled population, regulatory and malpractice issues, and compromised care. The physician is also faced with a number of difficult issues when caring for chronic wound patients because their conditions are time consuming and high risk, represent an unprofitable part of care practice and raise issues of liability. Telemedicine enhances communication with the surgical wound care specialist. Digital image for skin lesions is a safe, accurate and cost-effective referral pathway. The two basic modes of telemedicine applications, store and forward (asynchronous transfer and real-time transmission (synchronous transfer, e.g. video conference, are utilized in the wound care setting. Telemedicine technology in the hands of an experienced physician can streamline management of a problem wound. Although there is always an element of anxiety related to technical change, the evolution of wound care telemedicine technology has demonstrated a predictable maturation process.

    Interference alignment (IA) is a promising technique that allows high-capacity gains in interference channels, but which requires the knowledge of the channel state information (CSI) for all the system links. We design low-complexity and low-bit rate feedback strategies where a quantized version of some CSI parameters is fed back from the user terminal (UT) to the base station (BS), which shares it with the other BSs through a limited-capacity backhaul network. This information is then used by BSs to perform the overall IA design. With the proposed strategies, we only need to send part of the CSI information, and this can even be sent only once for a set of data blocks transmitted over time-varying channels. These strategies are applied to iterative MMSE-based IA techniques for the downlink of broadband wireless OFDM systems with limited feedback. A new robust iterative IA technique, where channel quantization errors are taken into account in IA design, is also proposed and evaluated. With our proposed strategies, we need a small number of quantization bits to transmit and share the CSI, when comparing with the techniques used in previous works, while allowing performance close to the one obtained with perfect channel knowledge.

  6. BETTER FINGERPRINT IMAGE COMPRESSION AT LOWER BIT-RATES: AN APPROACH USING MULTIWAVELETS WITH OPTIMISED PREFILTER COEFFICIENTS

    Directory of Open Access Journals (Sweden)

    N R Rema

    2017-08-01

    Full Text Available In this paper, a multiwavelet based fingerprint compression technique using set partitioning in hierarchical trees (SPIHT algorithm with optimised prefilter coefficients is proposed. While wavelet based progressive compression techniques give a blurred image at lower bit rates due to lack of high frequency information, multiwavelets can be used efficiently to represent high frequency information. SA4 (Symmetric Antisymmetric multiwavelet when combined with SPIHT reduces the number of nodes during initialization to 1/4th compared to SPIHT with wavelet. This reduction in nodes leads to improvement in PSNR at lower bit rates. The PSNR can be further improved by optimizing the prefilter coefficients. In this work genetic algorithm (GA is used for optimizing prefilter coefficients. Using the proposed technique, there is a considerable improvement in PSNR at lower bit rates, compared to existing techniques in literature. An overall average improvement of 4.23dB and 2.52dB for bit rates in between 0.01 to 1 has been achieved for the images in the databases FVC 2000 DB1 and FVC 2002 DB3 respectively. The quality of the reconstructed image is better even at higher compression ratios like 80:1 and 100:1. The level of decomposition required for a multiwavelet is lesser compared to a wavelet.

    While telemedicine's clinical effectiveness and educational benefits are accepted, its cost-effectiveness is controversial. This study focuses on telemedicine's cost-effectiveness from a provider's perspective. Reviews of the cost-effectiveness literature in telemedicine are critical of past studies' (a) methodological and analytical weaknesses; (b) focus on answering "Can we do this?" rather than "Should we do this?"; and (c) emphasis on patient benefits. Value chain analysis examines structural and executional cost drivers; a self-sustaining business model balances the cost and value associated with each telemedicine activity. We illustrate this analysis in a rural health program, examining teleradiography and telerehabilitation.

    Space medicine presents unique challenges and opportunities for epidemiologists, such as the use of telemedicine during spaceflight. Medical capabilities aboard the International Space Station (ISS) are limited due to severe restrictions on power, volume, and mass. Consequently, inflight health information is based heavily on crewmember (CM) self-report of signs and symptoms, rather than formal diagnoses. While CM's are in flight, the primary source of crew health information is verbal communication between physicians and crewmembers. In 2010 NASA implemented the Lifetime Surveillance of Astronaut Health, an occupational surveillance program for the U.S. Astronaut corps. This has shifted the epidemiological paradigm from tracking diagnoses based on traditional terrestrial clinical practice to one that incorporates symptomatology and may gain a more population-based understanding of early detection of disease process.

    Despite the rapid progress in optical imaging, most of the advanced microscopy modalities still require complex and costly set-ups that unfortunately limit their use beyond well equipped laboratories. In the meantime, microscopy in resource-limited settings has requirements significantly different from those encountered in advanced laboratories, and such imaging devices should be cost-effective, compact, light-weight and appropriately accurate and simple to be usable by minimally trained personnel. Furthermore, these portable microscopes should ideally be digitally integrated as part of a telemedicine network that connects various mobile health-care providers to a central laboratory or hospital. Toward this end, here we demonstrate a lensless on-chip microscope weighing approximately 46 grams with dimensions smaller than 4.2 cm x 4.2 cm x 5.8 cm that achieves sub-cellular resolution over a large field of view of approximately 24 mm(2). This compact and light-weight microscope is based on digital in-line holography and does not need any lenses, bulky optical/mechanical components or coherent sources such as lasers. Instead, it utilizes a simple light-emitting-diode (LED) and a compact opto-electronic sensor-array to record lensless holograms of the objects, which then permits rapid digital reconstruction of regular transmission or differential interference contrast (DIC) images of the objects. Because this lensless incoherent holographic microscope has orders-of-magnitude improved light collection efficiency and is very robust to mechanical misalignments it may offer a cost-effective tool especially for telemedicine applications involving various global health problems in resource limited settings.

We establish a method for this study, where we define two actor roles and ways...... of characterizing actor contributions, and apply the method to the largest healthcare region of Denmark. Our findings reveal an ecosystem that is relatively closed to new actors, where the actors tend to be related to single telemedicine applications, the applications have low connectivity, and the most influential...... actors of the ecosystem can be characterised as both being beneficial and inhibitory to the ecosystem prosperity....

    Two orthogonal modulation optical label switching(OLS) schemes, which are based on payload of polarization multiplexing-differential quadrature phase shift keying(POLMUX-DQPSK or PDQ) modulated with identifications of duobinary (DB) label and pulse position modulation(PPM) label, are researched in high bit-rate OLS network. The BER performance of hybrid modulation with payload and label signals are discussed and evaluated in theory and simulation. The theoretical BER expressions of PDQ, PDQ-DB and PDQ-PPM are given with analysis method of hybrid modulation encoding in different the bit-rate ratios of payload and label. Theoretical derivation results are shown that the payload of hybrid modulation has a certain gain of receiver sensitivity than payload without label. The sizes of payload BER gain obtained from hybrid modulation are related to the different types of label. The simulation results are consistent with that of theoretical conclusions. The extinction ratio (ER) conflicting between hybrid encoding of intensity and phase types can be compromised and optimized in OLS system of hybrid modulation. The BER analysis method of hybrid modulation encoding in OLS system can be applied to other n-ary hybrid modulation or combination modulation systems.

    Telemedicine is an application of information and communication technology in the healthcare environment. This study aimed to compare knowledge and perceptions of telemedicine technology among different groups of clinicians. This survey study was conducted in 2013. The potential participants included 532 clinicians who worked in two hospitals and three clinics in a northern province of Iran. Data were collected using a five-point Likert-scale questionnaire. The content validity of the questionnaire was checked, and the reliability was calculated using Cronbach's alpha coefficient (α = 0.73). The results showed that most of the clinicians (96.1 percent) had little knowledge about telemedicine. They perceived the advantages of telemedicine at a moderate level and its disadvantages at a low level. The knowledge of dentists about this technology was less than that of other groups, and as a result they were less positive about the advantages of telemedicine compared to nurses, general physicians, and specialists. The limited knowledge of clinicians about telemedicine seems to have influenced their perceptions of the technology. Therefore, providing healthcare professionals with more information about new technologies in healthcare, such as telemedicine, can help to gain a more realistic picture of their perceptions.

    Problem. Due to the rapid progress in the fields of information technology and data networks, telemedicine applications are growing in number. Besides curative telemedicine, the electronic exchange of medical data and the integration of health information systems between health care providers is gaining importance. Through the improved accessibility of electronic patient record information, considerable risks arise.Methods. A project for the interconnection of medical picture archiving and communication systems (PACS) between several hospitals is presented and the possibilities for further developing such networking systems utilizing new software technologies for transparent data access between different locations (GRID) and for decision support (software agents) are considered.Results. The availability of the electronic patient record via the data network and the perspective of semi intelligent software systems automatically preparing the data bears great potential for a boost in treatment quality and efficiency. Systems for unique electronic patient identification and for secure digital signature are a prerequisite, but per se not enough to ensure the protection of data against illegitimate access.Conclusion. Despite quality and efficiency benefits, challenges in the protection of sensible data and in the change of the physicians role result. (orig.) [de

    2008-12-01

    Telemedical wound care is one of the applications of teledermatology. We present our experience using telemedicine in the successful assessment and treatment of three patients with hard-to-heal ulcers. Three patients were seen at the PEMEX General Hospital in Veracruz, Mexico. The first patient was a 53-year-old man with hypertension, morbid obesity, chronic venous insufficiency, recurrent erysipelas, leg ulcers and lymphoedema. There was one ulcer on his left lower leg (20 x 10 cm) and one on his right leg (9 x 7 cm). The second patient was a 73-year-old woman with class III obesity and ulcers in her right leg, secondary to surgical debridement of bullous erysipelas. The third patient was a 51-year-old female with rheumatoid arthritis with one ulcer on each leg and chronic lymphostasis. Photographs with a digital camera were taken and sent weekly via email to a wound care specialist in Mexico City. The photographs allowed the expert to diagnose and evaluate the chronic wounds periodically. In the present cases, telemedicine allowed us to have a rapid evaluation, diagnosis and treatment. The images were of enough quality to be useful and small enough to be sent via regular email to the remote physician who immediately gave his feedback. The expert was confident to give therapeutic recommendations in this way, and we considered this method to be very cost-effective, saving the patient and the health care system, especially in transportation.

    Tele-ophthalmology has been employed mainly for patients in under-served rural areas in need of specialty care, but other applications such as telementoring have also been used. In certain populations, cost containment is a significant issue and telemedicine is a solution. Tele-ophthalmology can be performed in realtime, by store-and-forward mode, or by hybrid techniques. After appropriate modification, a range of peripherals may be used for tele-ophthalmology, including the direct ophthalmoscope, indirect ophthalmoscope, slit lamp or retinal camera. Tele-ophthalmology applications include: detecting, screening and diagnosing diabetic retinopathy; anterior segment imaging; glaucoma screening; low vision consultation; telementoring. Tele-ophthalmology shows great promise for improving patient care and increasing access to specialty care not available in under-served areas. In developing countries tele-ophthalmology may be a cost-effective method by which richer countries can assist them.

  1. Efficient Hybrid Watermarking Scheme for Security and Transmission Bit Rate Enhancement of 3D Color-Plus-Depth Video Communication

    Three-Dimensional Video-plus-Depth (3DV + D) comprises diverse video streams captured by different cameras around an object. Therefore, there is a great need to fulfill efficient compression to transmit and store the 3DV + D content in compressed form to attain future resource bounds whilst preserving a decisive reception quality. Also, the security of the transmitted 3DV + D is a critical issue for protecting its copyright content. This paper proposes an efficient hybrid watermarking scheme for securing the 3DV + D transmission, which is the homomorphic transform based Singular Value Decomposition (SVD) in Discrete Wavelet Transform (DWT) domain. The objective of the proposed watermarking scheme is to increase the immunity of the watermarked 3DV + D to attacks and achieve adequate perceptual quality. Moreover, the proposed watermarking scheme reduces the transmission-bandwidth requirements for transmitting the color-plus-depth 3DV over limited-bandwidth wireless networks through embedding the depth frames into the color frames of the transmitted 3DV + D. Thus, it saves the transmission bit rate and subsequently it enhances the channel bandwidth-efficiency. The performance of the proposed watermarking scheme is compared with those of the state-of-the-art hybrid watermarking schemes. The comparisons depend on both the subjective visual results and the objective results; the Peak Signal-to-Noise Ratio (PSNR) of the watermarked frames and the Normalized Correlation (NC) of the extracted watermark frames. Extensive simulation results on standard 3DV + D sequences have been conducted in the presence of attacks. The obtained results confirm that the proposed hybrid watermarking scheme is robust in the presence of attacks. It achieves not only very good perceptual quality with appreciated PSNR values and saving in the transmission bit rate, but also high correlation coefficient values in the presence of attacks compared to the existing hybrid watermarking schemes.

  2. Forensic watermarking and bit-rate conversion of partially encrypted AAC bitstreams

    Electronic Music Distribution (EMD) is undergoing two fundamental shifts. The delivery over wired broadband networks to personal computers is being replaced by delivery over heterogeneous wired and wireless networks, e.g. 3G and Wi-Fi, to a range of devices such as mobile phones, game consoles and in-car players. Moreover, restrictive DRM models bound to a limited set of devices are being replaced by flexible standards-based DRM schemes and increasingly forensic tracking technologies based on watermarking. Success of these EMD services will partially depend on scalable, low-complexity and bandwidth eficient content protection systems. In this context, we propose a new partial encryption scheme for Advanced Audio Coding (AAC) compressed audio which is particularly suitable for emerging EMD applications. The scheme encrypts only the scale-factor information in the AAC bitstream with an additive one-time-pad. This allows intermediate network nodes to transcode the bitstream to lower data rates without accessing the decryption keys, by increasing the scale-factor values and re-quantizing the corresponding spectral coeficients. Furthermore, the decryption key for each user is customized such that the decryption process imprints the audio with a unique forensic tracking watermark. This constitutes a secure, low-complexity watermark embedding process at the destination node, i.e. the player. As opposed to server-side embedding methods, the proposed scheme lowers the computational burden on servers and allows for network level bandwidth saving measures such as multi-casting and caching.

    Self-management skills are essential for patients with diabetes mellitus to minimise the risks of complications from their condition. The aim of this research was to develop a web-based application for self-management of type 1 diabetes, suitable for use by patients, their carers and physicians. The study was comprised of two phases, the first being analysis of the kind of information and capabilities required by potential users of the system. Based on the results derived from the first phase of the study, the system prototype was designed and then evaluated using the 'think aloud' method and a standard questionnaire. The application was designed for use by patients, their carers and physicians. Patients could enter the level of blood glucose, insulin and activities on a daily basis, and physicians were able to supervise a patient's health status from a distance. Users were generally satisfied with the final version of the system. People with a wide range of literacy skills were able to use the system effectively. Patients or their carers could use the web-based application as a log book by entering the level of blood glucose and insulin doses on a regular basis, and as an educational resource to improve self-management skills. Physicians could use the system at any time convenient to them to support patients by giving medical advice. Further research is needed to report the effectiveness of the system in practice.

  5. Role of telemedicine and mid-level dental providers in expanding dental-care access: potential application in rural Australia.

    Despite great progress in oral health over the past three decades, the rates of caries remain high in Australia, particularly among underserved populations. The reasons for poor oral health amongst underserved populations are multiple, but rests with socio-economic determinants of health. The present review considers international workforce models that have been created to enhance the recruitment and retention of dental providers in rural areas. Several strategies have been developed to address care access problems in rural areas, including the use of telemedicine and mid-level dental providers (MLDPs). Despite ongoing opposition from dentistry organisations, the Alaska and Minnesota workforce models have proven that developing and deploying dental therapists from rural communities has the potential to address the unmet needs of underserved populations. It is more efficient and cost-effective for MLDPs to perform triage and treat simple cases and for dentists to treat complicated cases. The use of MLDPs is intended to increase the capacity of the dental workforce in areas that are too isolated to entice dentists. Telemedicine has emerged as one solution to address limited access to health care, particularly in locations where there is a lack of providers. Telemedicine not only provides access to care, but also offers support, consultations and access to continuing education for practicing dental providers in rural areas. This strategy has the potential to free up resources to increase care access and reduce oral health disparities, thereby contributing to closing the rural-urban oral health gap. © 2016 FDI World Dental Federation.

    Although Botswana has recently been categorised as an upper middle income country, it is burdened by a scarcity of resources, both human and technological. There are barriers to patients' access to specialized care and healthcare providers' access to medical knowledge. Over the past three years, the Botswana-University of Pennsylvania Partnership (BUP) has piloted four mobile telemedicine projects in the specialties of women's health (cervical cancer screening utilizing visual inspection with acetic acid), radiology, oral medicine and dermatology. Mobile telemedicine has been used in 11 locations in Botswana, training a total of 24 clinicians and successfully contributing to the management of 643 cases. In addition to mobile telemedicine, BUP has initiated an m-learning programme with the University of Botswana School of Medicine. While successfully providing patients and providers with improved access to healthcare resources, the m-health projects have faced numerous technical and social challenges. These include malfunctioning mobile devices, unreliable IT infrastructure, accidental damage to mobile devices, and cultural misalignment between IT and healthcare providers. BUP has worked with its local partners to develop solutions to these problems. To ensure sustainability, m-health programmes must have strategic goals that are aligned with those of the national health and education system, and the initiatives must be owned and led by local stakeholders. Whenever possible, open source technology and local IT expertise and infrastructure should be employed.

    2016-06-01

    There is a widening gap between sleep provider access and patient demand for it. An American Academy of Sleep Medicine position paper recently recognized sleep telemedicine as one tool to narrow that divide. We define the term sleep telemedicine as the use of sleep-related medical information exchanged from one site to another via electronic communications to improve a patient's health. Applicable data transfer methods include telephone, video, smartphone applications, and the Internet. Their usefulness for the treatment of insomnia and sleep-disordered breathing is highlighted. Sleep telemedicine programs range in complexity from telephone-based patient feedback systems to comprehensive treatment pathways incorporating real-time video, telephone, and the Internet. While large, randomized trials are lacking, smaller studies comparing telemedicine with in-person care suggest noninferiority in terms of patient satisfaction, adherence to treatment, and symptomatic improvement. Sleep telemedicine is feasible from a technological and quality-driven perspective, but cost uncertainties, complex reimbursement structures, and variable licensing rules remain significant challenges to its feasibility on a larger scale. As legislative reform pends, larger randomized trials are needed to elucidate impact on patient outcomes, cost, and health-care system accessibility. Published by Elsevier Inc.

Material and method: Lessons have been drawn from 4 years practice of telemedicine between Luxemburg and 5 European centres. Problems so raised have been confronted with the US and EU literature. Results: Academic applications (web sites, teaching, hospital networks) are yet functional and are not dealt with here. Difficulties arise in case of 1st reading (e.g. 24 hour service), 2nd reading (expert advice) or distant reading (locum, service in remote places). In most applications, the relation is doctor to doctor; patient issues like quality of content, freedom of choice are minor. A body of laws, rules and directives apply to other issues. Confidentiality is ruled by the EU Directives on the Protection of Individuals and on Data Protection. Data are commonly encrypted/anonymized. Consent and free choice are ruled by the law of medicine. A doctor requiring 2nd advice stays in charge of the patient (no need to consent). Remote reading or 1st reading is usually based on prior agreement between doctors (like after hours service), and information or consent is recommended. Registration and accreditation are ruled by the Directives of the European Internal Market for Services. No obstacle to the delivery of services across the EU would remain if it is perceived that a tele-patient consults abroad rather than a tele-doctor practices abroad. (author)

    Telemedicine is an evolving technology that is used for health education, health care administration, and health care distribution. The potential benefits of telemedicine include a decrease in travel expenses, improved continuity of care, and increased access to specialized consultants, thus meeting the needs of patients, practitioners, and communities. Telemedicine has many evolving applications, including improved access to health care in medically underserved and rural areas. Regions Burn Center assessed the efficacy and efficiency of burn visits via telemedicine and identified the barriers and benefits specific to burn care. Information regarding travel costs and financial data were evaluated from a total of 1000 burn follow-up visits with 294 patients via telemedicine during a 5-year interval. Our results indicate that telemedicine burn visits are a cost-effective clinical alternative for the patient. However, telemedicine can be a financial burden to health care systems and inefficient for health care providers.

  16. Adaptive Long-Term Coding of LSF Parameters Trajectories for Large-Delay/Very- to Ultra-Low Bit-Rate Speech Coding

    Directory of Open Access Journals (Sweden)

    Laurent Girin

    2010-01-01

    Full Text Available This paper presents a model-based method for coding the LSF parameters of LPC speech coders on a “long-term” basis, that is, beyond the usual 20–30 ms frame duration. The objective is to provide efficient LSF quantization for a speech coder with large delay but very- to ultra-low bit-rate (i.e., below 1 kb/s. To do this, speech is first segmented into voiced/unvoiced segments. A Discrete Cosine model of the time trajectory of the LSF vectors is then applied to each segment to capture the LSF interframe correlation over the whole segment. Bi-directional transformation from the model coefficients to a reduced set of LSF vectors enables both efficient “sparse” coding (using here multistage vector quantizers and the generation of interpolated LSF vectors at the decoder. The proposed method provides up to 50% gain in bit-rate over frame-by-frame quantization while preserving signal quality and competes favorably with 2D-transform coding for the lower range of tested bit rates. Moreover, the implicit time-interpolation nature of the long-term coding process provides this technique a high potential for use in speech synthesis systems.

    Norway has a long history of using telemedicine, especially for geographical reasons. Despite the availability of promising telemedicine applications and the implementation of national initiatives and policies, the sustainability and scaling-up of telemedicine in the health system is still far from accomplished. The main objective of this study was to explore and identify the multi-level (micro, meso and macro) factors affecting telemedicine utilization in Norway. We used a mixed methods approach. Data from a national registry were collected to analyze the use of outpatient visits and telemedicine contacts in Norway from 2009 to 2015. Interviews with key stakeholders at national, regional and local level helped complete and contextualize the data analysis and explore the main issues affecting the use of telemedicine by health authorities and hospitals. Relevant national documents were also used to support, contradict, contextualize or clarify information and data. Telemedicine use in Norway from 2009 to 2015 remained very low, not exceeding 0.5% of total outpatient activity at regional level and 0.1% at national level. All four regions used telemedicine. Of the 29 hospitals, 24 used it at least once over the 7-year period. Telemedicine was not used regularly everywhere, with some hospitals using it sporadically. Telemedicine was mostly used in selected specialties, including rehabilitation, neurosurgery, skin and venereal diseases. Three major themes affecting implementation and utilization of telemedicine in Norway emerged: (i) governance and strategy; (ii) organizational and professional dimensions; (iii) economic and financial dimensions. For each theme, a number of factors and challenges faced at different health care levels were identified. This study allowed shedding light on multi-level and interdependent factors affecting utilization of telemedicine in Norway. The identification of the main implementation and utilization challenges might support decision

    Full Text Available Telemedicine is the use of electronic information and communication technology to provide and support healthcare when distance separates the participants. India is characterised by low penetration of healthcare services where primary healthcare facilities for rural population are highly inadequate. The majority of doctors practice in urban and semi-urban areas, whereas the major proportion of population lives in rural areas. This calls for the innovative methods for utilisation of science and technology for the benefit of our society. There are few reports in the literature which support the use of telemedicine technology for pre-operative assessment, intra-operative consultation, monitoring and post-operative follow-up, which is discussed in this article.

  3. Illumination-tolerant face verification of low-bit-rate JPEG2000 wavelet images with advanced correlation filters for handheld devices

    Wijaya, Surya Li; Savvides, Marios; Vijaya Kumar, B. V. K.

    2005-02-01

    Face recognition on mobile devices, such as personal digital assistants and cell phones, is a big challenge owing to the limited computational resources available to run verifications on the devices themselves. One approach is to transmit the captured face images by use of the cell-phone connection and to run the verification on a remote station. However, owing to limitations in communication bandwidth, it may be necessary to transmit a compressed version of the image. We propose using the image compression standard JPEG2000, which is a wavelet-based compression engine used to compress the face images to low bit rates suitable for transmission over low-bandwidth communication channels. At the receiver end, the face images are reconstructed with a JPEG2000 decoder and are fed into the verification engine. We explore how advanced correlation filters, such as the minimum average correlation energy filter [Appl. Opt. 26, 3633 (1987)] and its variants, perform by using face images captured under different illumination conditions and encoded with different bit rates under the JPEG2000 wavelet-encoding standard. We evaluate the performance of these filters by using illumination variations from the Carnegie Mellon University's Pose, Illumination, and Expression (PIE) face database. We also demonstrate the tolerance of these filters to noisy versions of images with illumination variations.

    Telemedicine is the rapidly developing application of clinical medicine by telephone, the internet or other networks for the purpose of consulting, and on occasions carrying out examinations or medical procedures. Telemedicine may be as simple as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries. Telemedicine offers real benefits in a country as vast as India where the majority of the population lives in remote areas with no access to even the most basic healthcare. As the practice of telemedicine spreads, maintaining standards, security and privacy, will be a challenge especially with regard to legal and regulatory measures and who will be held responsible if telemedicine-assisted surgery fails due to failure in connectivity? Is it the surgeon, the satellite provider or the software/hardware engineer? What is the legal status of telemedicine-based diagnosis and treatment? Other legal issues involve conflicting national laws and information piracy, the dangers of prescription drugs that are banned in one country but not in another and quacks who offer medical advice and prescribe drugs over the internet. This paper discusses some of the legal, ethical and social considerations in the Indian context.

    The next era of space exploration, especially the "Mission to Planet Earth" will generate immense quantities of image data. For example, the Earth Observing System (EOS) is expected to generate in excess of one terabyte/day. NASA confronts a major technical challenge in managing this great flow of imagery: in collection, pre-processing, transmission to earth, archiving, and distribution to scientists at remote locations. Expected requirements in most of these areas clearly exceed current technology. Part of the solution to this problem lies in efficient image compression techniques. For much of this imagery, the ultimate consumer is the human eye. In this case image compression should be designed to match the visual capacities of the human observer. We have developed three techniques for optimizing image compression for the human viewer. The first consists of a formula, developed jointly with IBM and based on psychophysical measurements, that computes a DCT quantization matrix for any specified combination of viewing distance, display resolution, and display brightness. This DCT quantization matrix is used in most recent standards for digital image compression (JPEG, MPEG, CCITT H.261). The second technique optimizes the DCT quantization matrix for each individual image, based on the contents of the image. This is accomplished by means of a model of visual sensitivity to compression artifacts. The third technique extends the first two techniques to the realm of wavelet compression. Together these two techniques will allow systematic perceptual optimization of image compression in NASA imaging systems. Many of the image management challenges faced by NASA are mirrored in the field of telemedicine. Here too there are severe demands for transmission and archiving of large image databases, and the imagery is ultimately used primarily by human observers, such as radiologists. In this presentation I will describe some of our preliminary explorations of the applications

    Full Text Available Introduction: Telemedicine connects emergency departments (ED with resources necessary for patient care; its use has not been characterized nationally, or even regionally. Our primary objective was to describe the prevalence of telemedicine use in New England EDs and the clinical applications of use. Secondarily, we aimed to determine if telemedicine use was associated with consultant availability and to identify ED characteristics associated with telemedicine use. Methods: We analyzed data from the National Emergency Department Inventory-New England survey, which assessed basic ED characteristics in 2014. The survey queried directors of every ED (n=195 in the six New England states (excluding federal hospitals and college infirmaries. Descriptive statistics characterized ED telemedicine use; multivariable logistic regression identified independent predictors of use. Results: Of the 169 responding EDs (87% response rate, 82 (49% reported using telemedicine. Telemedicine EDs were more likely to be rural (18% of users vs. 7% of non-users, p=0.03; less likely to be academic (1% of users vs. 11% of non-users, p=0.01; and less likely to have 24/7 access to neurology (p<0.001, neurosurgery (p<0.001, orthopedics (p=0.01, plastic surgery (p=0.01, psychiatry (p<0.001, and hand surgery (p<0.001 consultants. Neuro/stroke (68%, pediatrics (11%, psychiatry (11%, and trauma (10% were the most commonly reported applications. On multivariable analysis, telemedicine was more likely in rural EDs (odds ratio [OR] 4.39, 95% confidence interval [CI] 1.30–14.86, and less likely in EDs with 24/7 neurologist availability (OR 0.21, 95% CI [0.09–0.49], and annual volume <20,000 (OR 0.24, 95% CI [0.08–0.68]. Conclusion: Telemedicine is commonly used in New England EDs. In 2014, use was more common among rural EDs and EDs with limited neurology consultant availability. In contrast, telemedicine use was less common among very low-volume EDs.

    Full Text Available The use of assistive technology and telemedicine is likely to continue to shape our medical practice in the future, notably in the field of sleep medicine, especially within developed countries. Currently, the number of people suffering from obstructive sleep apnea syndrome (OSAS is increasing. Telemedicine (TM can be used in a variety of ways in sleep medicine: telediagnostics, teleconsultation, teletherapy and telemonitoring of patients being treated with positive pressure devices. In this review, we aim to summarize the recent scientific progresses of these techniques and their potential clinical applications and give consideration to the remaining problems related to TM application.

  11. Clinical outcomes resulting from telemedicine interventions: a systematic review

    2001-11-01

    Full Text Available Abstract Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis. All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.

    Although there are multiple challenges facing the use of telemedicine in home health care, it seems likely that they will be resolved. This analysis projects significant increases in productivity and savings to be realized by implementing a telemedicine system (such as the Tevital Home Care System) compared with traditional home care services. Additional savings are expected as a result of the reduction in the utilization of medical services other than home health care. At the same time, telemedicine offers conceivable benefits such as improved access for consumers, extended coverage capability by home health care agencies, decreased inefficiencies attributable to the complications associated with agency personnel travel, improved agency capacity for preventive care, and, ultimately, heightened consumer satisfaction and both physical and psychological well-being. Taken together, these benefits make adoption of telemedicine technology by home care providers highly desirable.

    The application of wireless devices has led to a significant improvement in the quality delivery of care in telemedicine systems. Patients who live in a remote area are able to communicate with the healthcare provider and benefit from the doctor consultations. However, it has been a challenge to provide a secure telemedicine system, which captures users (patients and doctors) mobility and patient privacy. In this work, we present several secure protocols for telemedicine systems, which ensure the secure communication between patients and doctors who are located in different geographical locations. Our protocols are the first of this kind featured with confidentiality of patient information, mutual authentication, patient anonymity, data integrity, freshness of communication, and mobility. Our protocols are based on symmetric-key schemes and capture all desirable security requirements in order to better serve our objectives of research for secure telemedicine services; therefore, they are very efficient in implementation. A comparison with related works shows that our work contributes first comprehensive solution to capture user mobility and patient privacy for telemedicine systems. Copyright © 2018 Elsevier Inc.

    Full Text Available In this paper, we investigate optical network recommendations GPON and XG-PON with triple-play services in terms of physical reach, number of subscribers, transceiver design, modulation format and implementation cost. Despite of trends to increase the bit rate from 2.5 Gbps to 10 Gbps and beyond, TDM-PONs cannot cope with bandwidth requirements of future networks. TDM and WDM techniques can be combined, resulting in improved scalability. Longer physical reach can be achieved by deploying active network elements within the transmission path. We investigate these options by considering their potential coexistence at the physical layer. Subsequently, we analyse the upgrade of optical channels to 100 Gbps and 256 Gbps by using advanced modulation formats, which combine polarization division multiplexing with coherent detection and digital signal processing. We show that PDM-QPSK format is suitable for 100 Gbps systems and PDM-16QAM is more beneficial at 256 Gbps. Simulations are performed in the OptSim software environment.

    Glaucoma is a major cause of blindness. More than 80,000 Americans suffer permanent vision loss from the disease. Widespread screening is fundamental in limiting the incidence of glaucoma-associated blindness. This pilot study explored the use of stereo digital images taken at a primary care center for telemedicine review by an off-site specialist as a means of screening for glaucoma. Thirty-two diabetic patients were screened at a family medicine clinic. None had previously been diagnosed with glaucoma. A senior optometry student took stereoscopic digital and 35-mm optic disc photographs with a nonmydriatic retinal camera. The digital images were forwarded to a remote ophthalmologist for review. The conventional color stereo slide pairs of the same eyes were subsequently reviewed for comparison. Agreement on signs of glaucomatous disc changes between the two imaging systems was analyzed. Twenty-six of 32 eyes' digital and 35-mm photographs were analyzed. Six of 32 eyes (18.8%) could not be compared due to lack of matching 35-mm slides or digital images. Out of 26 eyes, lamina cribosa visibility was undeterminable in 8 eyes' digital images and 3 other eyes' 35-mm slides. Agreement among digital images and 35-mm slides of the remaining eyes was: 100%-vertical elongation, barring of vessels, bayoneting of vessels, and drance hemorrhage; 96.2%-focus notching of rim and rim pallor; 93.3%-lamina cribosa visability; 92. 3%-overpass cupping; 88.5%-focal enlargement; 84.6%-parapapillary halo; 80%-nerve fiber visibility; 65.4%-parapapillary atrophy. Parapapillary halo (p = 0.046) and nerve fiber layer visibility (p = 0.18) were detected on some 35-mm slides but not seen on matching digital views. Evaluations of cup-to-disc ratio (C/D) using both methods were in general agreement. However, some digital images were noted as too dark for assessing fine glaucomatous disc changes. Stereo digital images taken with a nonmydriatic camera by nonophthalmic photographers is a

    Telemedicine is defined as the use of electronic information and communication technologies to provide health care between distant people. Many activities in transfusion medicine could benefit from the application of telemedicine. To map the spread of the use of telemedicine in transfusion medicine in Italy, the Italian Society of Transfusion Medicine and Immunohaematology (SIMTI) performed a nationwide survey: the results are presented in this paper. A survey, dealing with different aspects of the use of telemedicine, was performed by sending a questionnaire to 280 Italian Blood Centres. The survey was designed to evaluate the diffusion of telemedicine and the features of the systems, with special attention to the systems' safety and legal adequacy. One section of the questionnaire was designed to identify the features of the systems considered essential by the respondents. Out of 280 Blood Services contacted, 196 (70%) filled in at least one of the questions of the online questionnaire. Globally the use of some form of telemedicine was reported by 70% of the respondents. Telemedicine is used for remote validation of laboratory tests by 32% of the Centres that responded, for remote biological validation of blood units by 34% and for assignment of blood components by 29%. Less frequently, telemedicine is used to control electronic refrigerators, for electronic blood requests and for bed-side identification of patients. The use of telemedicine is widespread in Italian Blood Services. There appears to be some heterogeneity between structures with regards to the evaluation of the systems' safety and their legal adequacy. No telemedicine system should be introduced into practice until it has proven to have the same standards of safety as the corresponding "on site" activity.

    A multimedia telemedicine system (MTS) using Transfer Control Protocol and Internet Protocol (TCP/IP) over the Internet is developed. Doctor with patient and doctor can communicate each other using this system. Real-time data, including audio, video and instant message (IM), and non-real-time data, including vital sign signals, radiological images with DICOM 3.0, file, bio-signal, bio-data and so on, can be exchanged on the system. This system's architecture is client/server mode. All data are encoded/compressed before transferring through Internet/Intranet. The real-time audio is encoded and decoded by MPEG (Moving Picture Experts Group) audio layer 3 algorithm and real-time video is encoded and decoded by MPEG-4. The software implementation of needed functionality without any externally attached hardware CODEC (Coder/Decoder) units enables the compact design with low cost. The real-time video has 25 frames per second at Local Area Network (LAN) and more than 20 frames per second at ADSL.

    1995-01-01

    Dealing with telemedicine including telediagnosis and teleassistance, we have to assess the legal and ethical components of medical liability. With medical telediagnosis, the dispersion of medical liabilities is the main risk: how can we ensure a clear identification of the medical liabilities involved in case of damage? From a legal point of view, the dispersion of the liabilities is not authorized and the use of telediagnosis must ensure a total transparence. As we cannot presently establish a separate amount for a medical act based on the cost of the image records and the cost of image interpretation, it is necessary to establish a contract. Today the most convenient is a contract similar to the usual contract between laboratories which implies that the liability belongs to the practitioner who has received the sample. In the future, other legal obligations may appear when telediagnosis develops. Indeed, the increase in reliability due to telediagnosis could be normally required as a part of the medical obligation to use the latest technology. On the opposite, the excessive use of teleassistance, when there is neither emergency nor medical isolation, is dangerous because it affects the integrity and the quality of the medical act. A medical practice without any clinical examination of the patient is contrary to medical ethics.

    There is some tacit understanding that telemedicine can provide cost efficiency along with increased access and equality of care for the geographically disadvantaged. However, concrete strategic guidance for healthcare organizations to attain these benefits is fragmented and limited in existing literature. Telemedicine programs need to move from a grant-funded to a profit-centered status to sustain their existence. This article extends work presented at a recent American Telemedicine Association Business and Finance Special Interest Group course to provide a conceptual framework for strategic planning and for effectively implementing telemedicine programs. An expert panel of telemedicine coordinators provides insight and recommendations.

We identify opportunities to control the level of quality for each attribute (ie, who is responsible for control of each attribute and when control can be exerted in relation to the encounter process. This analysis reveals that many quality attributes are in the hands of various stakeholders, and all attributes can be addressed proactively to some degree before the encounter begins.Conclusion: Identification of the quality attributes important to a telemedicine encounter from a patient perspective enables one to better design telemedicine encounters. This preliminary work not only identifies such attributes, but also ascertains who is best able to address quality issues prior to an encounter. For practitioners, explicit representation of the quality attributes of technology-based systems and processes and insight on controlling key attributes are essential to implementation, utilization, management, and common understanding.

    ABSTRACT Objective To describe the impact of the telemedicine application on the clinical process of care and its different effects on hospital culture and healthcare practice. Methods The concept of telemedicine through real time audio-visual coverage was implemented at two different hospitals in São Paulo: a secondary and public hospital, Hospital Municipal Dr. Moysés Deutsch, and a tertiary and private hospital, Hospital Israelita Albert Einstein. Results Data were obtained from 257 teleconsultations records over a 12-month period and were compared to a similar period before telemedicine implementation. For 18 patients (7.1%) telemedicine consultation influenced in diagnosis conclusion, and for 239 patients (92.9%), the consultation contributed to clinical management. After telemedicine implementation, stroke thrombolysis protocol was applied in 11% of ischemic stroke patients. Telemedicine approach reduced the need to transfer the patient to another hospital in 25.9% regarding neurological evaluation. Sepsis protocol were adopted and lead to a 30.4% reduction mortality regarding severe sepsis. Conclusion The application is associated with differences in the use of health services: emergency transfers, mortality, implementation of protocols and patient management decisions, especially regarding thrombolysis. These results highlight the role of telemedicine as a vector for transformation of hospital culture impacting on the safety and quality of care. PMID:26676268

    2012-04-01

    Telemedicine is rapidly developing telecommunication technology to provide medical information and services. The importance of telemedicine for neurosurgical emergencies was established with the fact that majority of the neurosurgical specialists are practicing in urban settings and in most of the rural areas, neurosurgical care is far off or non-existing. Countries with inadequate health care must incorporate telemedicine in their health care system. Telemedicine offers real benefits in a country as vast as India, where the majority of the population lives in remote areas with no access to even the most basic healthcare. Issues pertaining security, privacy, maintaining standards, and legal aspects are relevant. A recommended set of standards and guidelines for telemedicine needs to be set in place and constantly refined to promote the integrated growth of telemedicine in the country. The paper discusses various issues, shortcomings, and utility of telemedicine in India.

    Following the coming into force of the International Labour Organisation Maritime Labour Convention (ILO/MLC) and International Maritime Organisation Standards for Training, Certification and Watchkeeping, Manila 2010 (IMO/STCW) amendments, the objective of this article is to provide the shipping community with an initial assessment of the economic reasons and business case, in support of both publicly financed and private telemedicine being implemented on board commercial vessels. It provides the global scale of the requirement, the number of Telemedicine Assistance Services (TMAS) calls handled by participating TMAS, the average direct and indirect costs incurred by both TMAS and ship operators, responding to medical emergencies, and also provides a calculation of the market size of about 760 million Euro/year. It estimates a return on investment per ship, of implementing telemedicine on board to meet the MLC and STCW requirements at less than 1 year. 1. There are both financial and soft benefits, such as crew retention and being perceived as a quality employer offering a telemedicine service on board. 2. It is quite possible to obtain a 20% savings to the industry of perhaps 152 million Euro/year from the deployment of telemedicine on board. 3. The deployment of a telemedical service on ships is an opportunity to encourage further cooperation between TMAS and also with the private TMAS sector. 4. There is clearly a great need, on a global basis, for more cooperation, particularly in standardisation of pre-boarding medical files available, the equipmentrequired on board at a minimum, and level of service quality provided. 5. A collection of a common TMAS annual set of normalised statistics from the stakeholders in the maritime industry is needed. Should someone not be tasked with collecting this? 6. Open registries and countries where the private sector only providestele medicine, should be encouraged to work with the global public TMAS system and contribute to

    This paper presents an approach for an evaluation of finished telemedicine projects using qualitative methods. Telemedicine applications are said to improve the performance of health care systems. While there are countless telemedicine projects, the vast majority never makes the threshold from testing to implementation and diffusion. Projects were collected from German project databases in the area of telemedicine following systematically developed criteria. In a testing phase, ten projects were subject to a qualitative content analysis to identify limitations, need for further research, and lessons learned. Using Mayring's method of inductive category development, six categories of possible future research were derived. Thus, the proposed method is an important contribution to diffusion and translation research regarding telemedicine, as it is applicable to a systematic research of databases.

    Traditionally, rural areas in many countries are limited by a lack of access to health care due to the inherent challenges associated with recruitment and retention of healthcare professionals. Telemedicine, which uses communication technology to deliver medical services over distance, is an economical and potentially effective way to address this problem. In this research, we develop a new telepresence application using an Augmented Reality (AR) system. We explore the use of the Microsoft HoloLens to facilitate and enhance remote medical training. Intrinsic advantages of AR systems enable remote learners to perform complex medical procedures such as Point of Care Ultrasound (PoCUS) without visual interference. This research uses the HoloLens to capture the first-person view of a simulated rural emergency room (ER) through mixed reality capture (MRC) and serves as a novel telemedicine platform with remote pointing capabilities. The mentor's hand gestures are captured using a Leap Motion and virtually displayed in the AR space of the HoloLens. To explore the feasibility of the developed platform, twelve novice medical trainees were guided by a mentor through a simulated ultrasound exploration in a trauma scenario, as part of a pilot user study. The study explores the utility of the system from the trainees, mentor, and objective observers' perspectives and compares the findings to that of a more traditional multi-camera telemedicine solution. The results obtained provide valuable insight and guidance for the development of an AR-supported telemedicine platform.

    To determine the perceived utility and demand for the application of telemedicine for improved patient care between nonsurgical dental practitioners (GPs) and oral and maxillofacial surgeons (OMS). Two distinct questionnaires were made, one for GPs and one for OMSs. The GP questionnaire was sent to practicing Virginia Dental Association members on an e-mail list (approximately 2,200). The OMS questionnaire was sent by the Virginia Society of Oral Maxillofacial Surgery to members on an e-mail list (approximately 213). Questionnaires included questions about access to care, benefits of telemedicine consultations, reliability of telemedicine consultations, and perceived barriers against and opportunities for the implementation of telemedicine. The questionnaire was completed by 226 GP and 41 OMS respondents. There was a significant difference among responses of GPs based on practice location: rural patients had a longer average time from referral to OMS consultation (P = .003), rural patients traveled longer distances (P oral and maxillofacial surgery.

    Traditionally, telemedicine systems have been designed to improve access to care by allowing physicians to consult a specialist about a case without sending the patient to another location, which may be difficult or time-consuming to reach. The cost of the equipment and network bandwidth needed for this consultation has restricted telemedicine use to contact between physicians instead of between patients and physicians. Recently, however, the wide availability of Internet connectivity and client and server software for e- mail, world wide web, and conferencing has made low-cost telemedicine applications feasible. In this work, we present a web-based system for asynchronous multimedia messaging between shoulder replacement surgery patients at home and their surgeons. A web browser plug-in was developed to simplify the process of capturing video and transferring it to a web site. The video capture plug-in can be used as a template to construct a plug-in that captures and transfers any type of data to a web server. For example, readings from home biosensor instruments (e.g., blood glucose meters and spirometers) that can be connected to a computing platform can be transferred to a home telemedicine web site. Both patients and doctors can access this web site to monitor progress longitudinally. The system has been tested with 3 subjects for the past 7 weeks, and we plan to continue testing in the foreseeable future.

    Telemedicine can alleviate the increasing demand for elderly care caused by the rapidly aging population. However, user adherence to technology in telemedicine interventions is low and decreases over time. Therefore, there is a need for methods to increase adherence, specifically of the elderly user. A strategy that has recently emerged to address this problem is gamification. It is the application of game elements to nongame fields to motivate and increase user activity and retention. This research aims to (1) provide an overview of existing theoretical frameworks for gamification and explore methods that specifically target the elderly user and (2) explore user classification theories for tailoring game content to the elderly user. This knowledge will provide a foundation for creating a new framework for applying gamification in telemedicine applications to effectively engage the elderly user by increasing and maintaining adherence. We performed a broad Internet search using scientific and nonscientific search engines and included information that described either of the following subjects: the conceptualization of gamification, methods to engage elderly users through gamification, or user classification theories for tailored game content. Our search showed two main approaches concerning frameworks for gamification: from business practices, which mostly aim for more revenue, emerge an applied approach, while academia frameworks are developed incorporating theories on motivation while often aiming for lasting engagement. The search provided limited information regarding the application of gamification to engage elderly users, and a significant gap in knowledge on the effectiveness of a gamified application in practice. Several approaches for classifying users in general were found, based on archetypes and reasons to play, and we present them along with their corresponding taxonomies. The overview we created indicates great connectivity between these taxonomies

    Telemedicine has become an increasingly popular option for long-distance/virtual medical care and education, but many telemedicine ventures fail to grow beyond the initial pilot stage. Studying the business models of successful telemedicine ventures can help develop business strategies for upcoming ventures. This article describes business models of eight telemedicine ventures from different regions of the world using Osterwalder's "Business Model Canvas." The ventures are chosen on the basis of their apparent success and their diverse value chains. The business models are compared to draw inferences and lessons regarding their business strategy and contextual factors that influenced it. Key differences between telemedicine business practices in developing and developed countries are also discussed. The purpose of this article is to inform and inspire the business strategy of the next generation of telemedicine ventures to be economically sustainable and to successfully address local healthcare challenges.

  19. Worldwide trends in Universal Service Funds and telemedicine.

    2010-12-01

    A survey of recent worldwide trends in Universal Service Funds (USFs) and the assistance provided for their application indicates that industrialized countries and developing nations alike have offered or plan to offer tax-relief measures or reimbursement for communications costs incurred by telemedicine programs, thus finding a way to actively apply USFs in rural areas. There are three main systems used to calculate the amount of reimbursement from a USF. While many countries adopt a service-area net-loss estimation method, Japan uses a benchmark method and provides financial assistance only to unprofitable areas. The USA has proactively introduced telemedicine to rural areas and isolated islands in order to minimize rapidly rising healthcare costs and to improve the efficiency of healthcare services. In the USA, the USF is used to pay back communications costs incurred through telemedicine programs. For instance, the budget allocated from the USF for reimbursements for telemedicine in Alaska reached USD 30 Mil. in 2007. Developing countries in Africa and Asia are operating various forms of telemedicine on a trial basis, but a tax-relief measure or payback of communications costs, which are a large portion of the running costs, will need to be implemented to ensure sustainable and autonomous operation of telemedicine. In Japan, up until January 2007, the USF system assumed the use of an NTS (non-traffic sensitive cost) system to obtain funds from connection fees, and this system would receive funds from each telecommunications carrier (payer: the telecommunications carriers). The beneficiaries would be limited to two companies, namely NTT East and NTT West. However, the Japanese USF system was revised in February 2007, and a fee is now collected from each telephone number (payer: the user). The collected funds are used to cover losses in unprofitable areas (not limited to remote areas) among 7,000 business areas in Japan. In view of worldwide trends, the author

    Telemedicine has drawn increasing attention as one of the emerging new service delivery vehicles that will run on the information superhighway. In reality, remote diagnosis and consultation through the application of telecommunications technology have been practiced for many years. But advances in technology and reform imperatives to extend access beyond traditional boundaries are pushing telemedicine into new applications. This is evidenced by the explosion in the number of pilot projects begun within the last 12 months. While demonstrating telemedicine's growing capabilities--for education and administration, as well as medical practice--these projects also raise a number of legal, clinical, and technical questions that must be answered before government and other payers will routinely reimburse for remote services. Academic and industry consortia are springing up to deal with the most compelling issues, including documenting telemedicine's safety and efficacy, developing uniform data and transmission standards, and determining the minimum resolution needed to maintain the integrity of clinical transmissions. Almost every type of medical specialty has proved amenable to performing evaluations via telemedicine links; however, specialties with less direct patient contact, like radiology and pathology, are generally identified as better candidates for telemedicine interactions. The telemedicine equipment required for these consults ranges from the simple to the ultra-sophisticated, depending on the type of system used and its clinical application. The most common system configuration involves a base station in the main facility where specialists and other consultants are housed and a number of remote referral sites. Consults are performed by interactively sharing voice, video, or image data. Increasingly, systems are being introduced that use easy-to-learn, intuitive displays and controls. Systems also require the use of any number of different communication media

    2014-06-30

    Access to specialized burn care is becoming more difficult and is being restricted by the decreasing number of specialized burn centers. It is also limited by distance and resources for many patients, particularly those living in poverty or in rural medically underserved communities. Telemedicine is a rapidly evolving technology related to the practice of medicine at a distance through rapid access to remote medical expertise by telecommunication and information technologies. Feasibility of telemedicine in burn care has been demonstrated by various centers. Its use facilitates the delivery of care to patients with burn injuries of all sizes. It allows delivery of acute care and can be appropriately used for a substantial portion of the long-term management of patients after a burn by guiding less-experienced surgeons to treat and follow-up patients more appropriately. Most importantly, it allows better effective triage which reduces unnecessary time and resource demanding referrals that might overwhelm system capacities. However, there are still numerous barriers to the implementation of telemedicine, including technical difficulties, legal uncertainties, limited financial support, reimbursement issues, and an inadequate evidence base of its value and efficiency.

    This Workshop was designed to assist in the ongoing development and application of telemedicine and medical informatics to support extended space flight. Participants included specialists in telemedicine and medical/health informatics (terrestrial and space) medicine from NASA, federal agencies, academic centers, and research and development institutions located in the United States and several other countries. The participants in the working groups developed vision statements, requirements, approaches, and recommendations pertaining to developing and implementing a strategy pertaining to telemedicine and medical informatics. Although some of the conclusions and recommendations reflect ongoing work at NASA, others provided new insight and direction that may require a reprioritization of current NASA efforts in telemedicine and medical informatics. This, however, was the goal of the Workshop. NASA is seeking other perspectives and views from leading practitioners in the fields of telemedicine and medical informatics to invigorate an essential and high-priority component of the International Space Station and future extended exploration missions. Subsequent workshops will further define and refine the general findings and recommendations achieved here. NASA's ultimate aim is to build a sound telemedicine and medical informatics operational system to provide the best medical care available for astronauts going to Mars and beyond.

  8. A methodology for the development of software agent based interoperable telemedicine systems: a tele-electrocardiography perspective.

    2000-01-01

    Telemedicine involves the integration of information, human-machine, and healthcare technologies. Because different modalities of patient care require applications running on heterogeneous computing environment, software interoperability is a major issue in telemedicine. Software agent technology provides a range of promising techniques to solve this problem. This article discusses the development of a methodology for the design of interoperable telemedicine systems (illustrated with a tele-electrocardiography application). Software interoperability between different applications can be modeled at different levels of abstraction such as physical interoperability, data-type interoperability, specification-level interoperability, and semantic interoperability. Software agents address the issue of software interoperability at semantic level. A popular object-oriented software development methodology - unified modeling language (UML) - has been used for this development. This research has demonstrated the feasibility of the development of agent-based interoperable telemedicine systems. More research is needed before widespread deployment of such systems can take place.

    This paper describes the Medical College of Ohio's efforts in developing a client/server telemedicine system. Telemedicine vastly improves the ability of a medical center physician or specialist to interactively consult with a physician at a remote health care facility. The patient receives attention more quickly, he and his family do not need to travel long distances to obtain specialists' services, and the primary care physician can be involved in diagnosis and developing a treatment program [1, 2]. Telemedicine consultations are designed to improve access to health services in underserved urban and rural communities and reduce isolation of rural practitioners [3].

  10. Hospital Views of Factors Affecting Telemedicine Use.

    2015-04-01

    Telemedicine (also known as telehealth) is a means to increase access to care, one of the foundations of the Triple Aim. However, the expansion of telemedicine services in the United States has been relatively slow. We previously examined the extent of uptake of hospital based telemedicine using the 2013 HIMSS (Healthcare Information and Management Systems Society) Analytics national database of 4,727 non-specialty hospitals. Our analysis indicated that the largest percentage of operational telemedicine implementations (15.7 percent) was in radiology departments, with a substantial number in emergency/trauma care (7.5 percent) and cardiology/stroke/heart attack programs (6.8 percent). However, existing databases are limited because they do not identify whether a respondent hospital is a "hub" (providing telemedicine services) or a "spoke" (receiving telemedicine services). Therefore, we used data from interviews with hospital representatives to deepen the research and understanding of telemedicine use and the factors affecting that use. Interviews were conducted with key informants at 18 hub hospitals and 18 spoke hospitals to explore their perceptions of barriers and motivators to telemedicine adoption and expansion. Key Findings. (1) Respondents from both hub and spoke hospitals reported that telemedicine helps them meet their mission, enhances access, keeps lower-acuity patients closer to home, and helps head off competition. (2) Respondents from both hub and spoke hospitals reported licensing and credentialing to be significant barriers to telemedicine expansion. Thus, half of hubs provide services only within their state. (3) A variety of one-time funding sources have been used to initiate and grow telemedicine services among hubs and spokes. However, reimbursement issues have impeded the development of workable business models for sustainability. Hub hospitals shoulder the responsibility for identifying sustainable business models.

    2010-10-01

    Researchers in the domain of telemedicine throughout the world tend to search multiple bibliographic databases to retrieve the highest possible number of publications when conducting review projects. Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) are three popular databases in the discipline of biomedicine that are used for conducting reviews. Access to the MEDLINE database is free and easy, whereas EMBASE and CINAHL are not free and sometimes not easy to access for researchers in small research centers. This project sought to compare MEDLINE with EMBASE and CINAHL to estimate what proportion of potentially relevant publications would be missed when only MEDLINE is used in a review project, in comparison to when EMBASE and CINAHL are also used. Twelve simple keywords relevant to 12 different telemedicine applications were searched using all three databases, and the results were compared. About 9%-18% of potentially relevant articles would have been missed if MEDLINE had been the only database used. It is preferable if all three or more databases are used when conducting a review in telemedicine. Researchers from developing countries or small research institutions could rely on only MEDLINE, but they would loose 9%-18% of the potentially relevant publications. Searching MEDLINE alone is not ideal, but in a resource-constrained situation, it is definitely better than nothing.

    Full Text Available The ProblemEpilepsy is a common disease worldwide causing significant physical and social. disability. It is one of the most treatable neurological diseases. Yet in rural, poorer countries like much of India and Nepal most people with epilepsy are not on any treatment often because they cannot access doctors. Conventional ApproachesIt is being appreciated that perhaps doctors are not the solution and that enabling health workers to treat epilepsy may be better. Few details however have been put forward about how that might be achieved.Thinking differentlyUntreated epilepsy should be considered a public health problem like HIV/AIDS, the various steps needed for treatment identified and solutions found. Telemedicine ApproachesTelemedicine might contribute to two steps - diagnosis and review. A tool which enables non-doctors to diagnose episodes as epileptic has been developed as a mobile phone app and has good applicability, sensitivity and specificity for the diagnosis. There are a number of ways in which the use of phone review or SMS can improve management.ConclusionsTelemedicine, as part of a public health program, can potentially help the millions of people in the resource-poor world with untreated epilepsy.

  14. A Decision Support System For Equipment Allocation In A Telemedicine Referral Network

    Directory of Open Access Journals (Sweden)

    Treurnicht, Maria J.

    2014-05-01

    Full Text Available Telemedicine applications have had much success in strengthening health systems worldwide. Unfortunately, many systems are implemented without decisions based on proper needs assessments. In South Africa, this technology push approach has led to a large amount of equipment standing dormant. It is proposed that the potential of telemedicine be measured prior to implementation, thus pulling the technology towards a clinical need. A decision support system is developed that uses health informatics and computational intelligence to determine the need for telemedicine and to allocate equipment in a network of facilities to achieve the best cost benefit. The system facilitates the collection and storage of electronic health record (EHR data in a data warehouse. A linear programming model is used with a genetic algorithm. The system was developed and tested for the South African public health sector, using data from 27 hospitals in the Western Cape Province. Results have shown that if telemedicine workstations with specific peripheral equipment, as determined by the algorithm, were implemented in the given period, an estimated R8.7 million in referral costs could have been saved for the 27 hospitals. Thus the case study provided evidence for the benefits of implementation in the chosen network of hospitals. This new application of health informatics could provide telemedicine management with a useful tool for making implementation decisions based on evidence. Future work would include the development of similar systems for other markets.

    Full Text Available Abstract The provision of effective emergency telemedicine and home monitoring solutions are the major fields of interest discussed in this study. Ambulances, Rural Health Centers (RHC or other remote health location such as Ships navigating in wide seas are common examples of possible emergency sites, while critical care telemetry and telemedicine home follow-ups are important issues of telemonitoring. In order to support the above different growing application fields we created a combined real-time and store and forward facility that consists of a base unit and a telemedicine (mobile unit. This integrated system: can be used when handling emergency cases in ambulances, RHC or ships by using a mobile telemedicine unit at the emergency site and a base unit at the hospital-expert's site, enhances intensive health care provision by giving a mobile base unit to the ICU doctor while the telemedicine unit remains at the ICU patient site and enables home telemonitoring, by installing the telemedicine unit at the patient's home while the base unit remains at the physician's office or hospital. The system allows the transmission of vital biosignals (3–12 lead ECG, SPO2, NIBP, IBP, Temp and still images of the patient. The transmission is performed through GSM mobile telecommunication network, through satellite links (where GSM is not available or through Plain Old Telephony Systems (POTS where available. Using this device a specialist doctor can telematically "move" to the patient's site and instruct unspecialized personnel when handling an emergency or telemonitoring case. Due to the need of storing and archiving of all data interchanged during the telemedicine sessions, we have equipped the consultation site with a multimedia database able to store and manage the data collected by the system. The performance of the system has been technically tested over several telecommunication means; in addition the system has been clinically validated in three

    With the growth and popularity of the utilization of artificial intelligence (AI) in several fields and industries, studies in the field of medicine have begun to implement its capabilities in handling and analyzing data to telemedicine. With the challenges in the implementation of telemedicine, there has been a need to expand its capabilities and improve procedures to be specialized to solve specific problems. The versatility and flexibility of both AI and telemedicine gave the endless possibilities for development and these can be seen in the literature reviewed in this paper. The trends in the development of the utilization of this technology can be classified in to four: patient monitoring, healthcare information technology, intelligent assistance diagnosis, and information analysis collaboration. Each trend will be discussed and presented with examples of recent literature and the problems they aim to address. Related references will also be tabulated and categorized to see the future and potential of this current trend in telemedicine.

    Telemedicine is fast becoming popular in many countries in the world. It has several advantages such as being cost saving and providing better access to health care in the remote areas in many parts of the world. However, it has some disadvantages as well. One of the major problems is the problem of patients' rights and confidentiality in the use of telemedicine. There are no standard guidelines and procedures in the practice of telemedicine as yet. Both the patient and the physician are unsure of the standard of practice and how to maintain confidentiality. The patient is uncertain as to how to protect her/his rights in the use of telemedicine. The issue of litigation is also unclear as to where the physician is practicing when he/she uses telemedicine. Is she/he practicing in the country where the patient is or is the physician practicing in the country of her/his origin? These issues need to be addressed urgently so that telemedicine will have standards of ethical practice and the patient's rights and confidentiality will be protected.

    The increasing cost and inequitable access to quality healthcare, coupled with the merger of the information technology and health service sectors, has given rise to the modern field of telemedicine. Telemedicine, meaning medicine at a distance, allows us to transcend geographic and socioeconomic boundaries to deliver high quality care to remote and/or in-need patients. As technology becomes more affordable and a physician shortage looms, telemedicine is gaining attention as a possible solution to healthcare delivery. Simultaneously, telemedicine holds great promise with regard to medical education. Several studies integrating telemedicine in medical education have shown positive outcomes, demonstrating similar or greater efficacy compared with traditional educational methods with high student-reported enthusiasm. Other domestic and international telemedicine projects, largely spearheaded by universities, have also achieved great success. In a novel approach, by pairing medical schools with in-need partner communities, utilizing similar faculty resources as traditional learning methods with standardized patients, students can gain valuable experience and skills while serving actual patients. This progressive approach to medical education fosters collaboration, communication, longitudinal care and teaches students needed skills for their future practices as 21 st Century healthcare providers.

  4. The role of information communication technology (ICT) towards universal health coverage: the first steps of a telemedicine project in Ethiopia.

    2012-01-01

    Eighty-five per cent of the Ethiopian population lives in remote areas, without access to modern health services. The limited health care budget, chronic shortage of health care workers and lack of incentives to retain those in remote areas further jeopardize the national health care delivery system. Recently, the application of information communication technology (ICT) to health care delivery and the use of telemedicine have raised hopes. This paper analyzes the challenges, failures and successes encountered in setting-up and implementing a telemedicine program in Ethiopia and provides possible recommendations for developing telemedicine strategies in countries with limited resources. Ten sites in Ethiopia were selected to participate in this pilot between 2004 and 2006 and twenty physicians, two per site, were trained in the use of a store and forward telemedicine system, using a dial-up internet connection. Teledermatology, teleradiology and telepathology were the chosen disciplines for the electronic referrals, across the selected ten sites. Telemedicine implementation does not depend only on technological factors, rather on e-government readiness, enabling policies, multisectoral involvement and capacity building processes. There is no perfect 'one size fits all' technology and the use of combined interoperable applications, according to the local context, is highly recommended. Telemedicine is still in a premature phase of development in Ethiopia and other sub-Saharan African countries, and it remains difficult to talk objectively about measurable impact of its use, even though it has demonstrated practical applicability beyond reasonable doubts.

    The Brazilian National Telemedicine Program in indigenous healthcare assists health professionals working in remote areas in strengthening the healthcare provided to indigenous populations. The current study aimed to analyze the implementation of the National Telemedicine Program in indigenous people's health, from the perspective of health administrators. This was a qualitative exploratory descriptive study using document analysis and open-ended interviews with 10 administrators. Content analysis resulted in two categories: the program's process implementation and the potential of telemedicine for indigenous people's healthcare. The results emphasize the importance of dialogue between all institutions involved and the construction of a democratic forum for evaluating this process and related decision-making: resumption of the program's implementation and subsequently its expansion and improvement of the available resources and the search for other applicable strategies for indigenous people's health. A broad discussion on this topic is recommended that involves the indigenous people's strategies for social control.

    To investigate the application of a telemedicine intervention in diabetes foot ulcer care, and its implications for the healthcare professionals in the clinical field. Contextual factors are found to be important when applying technology in health care and applying telemedicine in home-based care has been identified as particularly complex. We conducted field observations and individual interviews among healthcare professionals in home-based care and specialist health care in a diabetes foot care telemedicine RCT (Clin.Trial.gov: NCT01710774) during 2016. This study was guided by Interpretive Description, an inductive qualitative methodology. Overall, we identified unequal possibilities for applying telemedicine in diabetes foot ulcer care within the hospital and home care contexts. Different circumstances and possibilities in home-based care made the application of telemedicine as intended more difficult. The healthcare professionals in both care contexts perceived the application of telemedicine to facilitate a more comprehensive approach towards the patients, but with different possibilities to enact it. Application of telemedicine in home-based care was more challenging than in the outpatient clinic setting. Introducing more updated equipment and minor structural adjustments in consultation time and resources could make the use of telemedicine in home-based care more robust. Application of telemedicine in diabetes foot ulcer follow-up may enhance the nursing staff's ability to conduct comprehensive assessment and care of the foot ulcer as well as the patient's total situation. Access to adequate equipment and time, particularly in home-based care, is necessary to capitalise on this new technology. © 2017 John Wiley & Sons Ltd.

    The challenges faced and the methods implemented by the Apollo Hospitals Group in introducing telemedicine in the Indian setting are discussed in this article. Using Information and Communication Technology (ICT) to make available secondary and tertiary medical expertise to suburban and rural India was thought of as early as 1997. In March 2000, the world's first Very Small Aperture Terminal (VSAT)-enabled village hospital was commissioned. Today, with 115 centers including 9 overseas, the Apollo Telemedicine Networking Foundation (ATNF) is the oldest and largest multispecialty telemedicine network. More than 57,000 teleconsultations in various disciplines, ranging from sexual medicine to neurosurgery, have been provided. Patients have been evaluated from distances ranging from 120 to 4,500 miles. A majority (85%) of these teleconsults were reviews. The successful proof of concept validation studies, carried out from 2000 to 2001 by Apollo, were instrumental in the Indian Space Research Organization (ISRO) including telemedicine as a major thrust area. The pioneering role played by Apollo is also discussed in using VSAT-enabled Hospitals on Wheels. The paper reviews the significant role played by ATNF in the growth and development of telemedicine in South Asia. Academic activities are also highlighted. The pioneering efforts in the field of m-health, home telecare, the Pan African e-Network Project, starting the first formal educational course in telehealth and various other e-initiatives are elaborated.

    For years ophthalmic photographs have been used to track the progression of many ocular diseases such as macular degeneration and glaucoma as well as the ocular manifestations of diabetes, hypertension, and hypoxia. In 1987 a project was initiated at the Johnson Space Center (JSC) to develop a means of monitoring retinal vascular caliber and intracranial pressure during space flight. To conduct telemedicine during space flight operations, retinal images would require real-time transmissions from space. Film-based images would not be useful during in-flight operations. Video technology is beneficial in flight because the images may be acquired, recorded, and transmitted to the ground for rapid computer digital image processing and analysis. The computer analysis techniques developed for this project detected vessel caliber changes as small as 3 percent. In the field of telemedicine, the Portable Dynamic Fundus Instrument demonstrates the concept and utility of a small, self-contained video funduscope. It was used to record retinal images during the Gulf War and to transmit retinal images from the Space Shuttle Columbia during STS-50. There are plans to utilize this device to provide a mobile ophthalmic screening service in rural Texas. In the fall of 1993 a medical team in Boulder, Colorado, will transmit real-time images of the retina during remote consultation and diagnosis. The research applications of this device include the capability of operating in remote locations or small, confined test areas. There has been interest shown utilizing retinal imaging during high-G centrifuge tests, high-altitude chamber tests, and aircraft flight tests. A new design plan has been developed to incorporate the video instrumentation into face-mounted goggle. This design would eliminate head restraint devices, thus allowing full maneuverability to the subjects. Further development of software programs will broaden the application of the Portable Dynamic Fundus Instrument in

    With the development of information and communication technologies, telemedicine has been proposed as a way to improve patient management by facilitating access to appropriate diagnosis and treatment. The Paris Ile de France Regional Health Agency is currently funding a comprehensive program of telemedicine experiments. This article describes the protocols for the evaluation of the implementation of telemedicine in the Paris region. Over 2,500 patients have been included in eight studies addressing the use of telemedicine in the context of specific diseases or settings. Two projects are randomized controlled trials, while the six other projects are based on before-after designs (differences in differences studies). Based on the MAST model and the French national framework, we identified endpoints to assess the impact of telemedicine on five dimensions: clinical effectiveness, cost-effectiveness, security of the application, patient satisfaction and quality of life and perception of professionals. Telemedicine encompasses a wide range of services and stakeholders, and thus study protocols must be tailored to the specific constraints and interests of the users.

    South Korean government is currently in progress of expanding the coverage of telemedicine projects as part of an attempt to vitalize service industry, but is facing fierce opposition from KMA. Practice of telemedicine requires sufficient discussions among related parties. Although the participation of medical specialists is important, agreement from the public is essential. Three main tertiary care centers in Seoul were selected for data collection. A total of 224 patients (patients n = 180, patient guardian n = 44) and medical professionals (n = 41) were selected using simple random sampling. Mixed method of quantitative survey and qualitative semi-interview was used. This study analyzed patients' and medical professionals' perception about the application of telemedicine in cardiology ward in tertiary care centers to provide baseline data when developing and applying telemedicine services. Results implied high need for encouraging telemedicine projects in order to appeal needs among population by providing experience (p < 0.001) and knowledge (p < 0.001). Other results showed that the need for electrocardiography monitoring was high among not only in remote areas but also in areas close to the capital. 64.52% of all participants thought that telemedicine was needed, and 73.21% of participants were willing to use telemedicine service if provided. Semi-interviews revealed that participants expected more cost and time saving services through remote treatment, by not having to visit long distance hospitals frequently. Research results oppose Korean Medical Association's opinion that the population is against enforcing telemedicine related laws. The findings in this study reflect an up-to-date perception of telemedicine among patients and medical professionals in a tertiary care centers' cardiology ward. Moreover, the study provides a baseline that is needed in order to overcome past failures and to successfully implement telemedicine in South

    Security and privacy are among the most crucial issues for data transmission in telemedicine systems. This paper proposes a solution for securing wireless data transmission in telemedicine systems, i.e. within a body sensor network (BSN), between the BSN and server as well as between the server and professionals who have assess to the server. A unique feature of this solution is the generation of random keys by physiological data (i.e. a biometric approach) for securing communication at all 3 levels. In the performance analysis, inter-pulse interval of photoplethysmogram is used as an example to generate these biometric keys to protect wireless data transmission. The results of statistical analysis and computational complexity suggest that this type of key is random enough to make telemedicine systems resistant to attacks.

    Increased use of smartphone and related software applications has created a new era in clinical data exchange among patients and clinicians. This study describes use of the smartphone-based application WhatsApp to share clinical oral medicine information. Clinical images and related questions were submitted by general dentists, physicians, dental hygienists, and patients to the authors via WhatsApp. For each submission, a clinical impression was made and categorized as traumatic, infective, neoplastic, autoimmune, or unclassified. Submissions were summarized by sender type, number of photographs per sender, and category of question. Patients were invited to undergo a clinical examination with biopsy, when indicated. The telemedicine impression was compared to the clinicopathologic diagnosis. Three hundred and thirty-nine images were received for 96 patients; 92 (95.8%) patients underwent clinicopathologic examination, and 45 (49%) received a biopsy. General dentists (62%) and dental hygienists (26%) were the most frequent senders. The most common question was related to diagnosis (56%). The telemedicine impression agreed with the clinicopathologic assessment for 82% of cases. Telemedicine applications, such as WhatsApp, can support communication about oral conditions among clinicians and patients. Telemedicine consultation reduced geographic barriers to initial clinical consultation and encouraged the significant majority of patients to pursue expert clinical examination.

    As a result of the various telemedicine projects in the past years a large number of studies were recently published in this field. However, a precise bibliometric analysis of telemedicine publications does not exist so far. The present study was conducted to establish a data base of the existing approaches. Density-equalizing algorithms were used and data was retrieved from the Thomson Reuters database Web of Science. During the period from 1900 to 2006 a number of 3290 filed items were connected to telemedicine, with the first being published in 1964. The studies originate from 101 countries, with the USA, Great Britain and Canada being the most productive suppliers participating in 56.08 % of all published items. Analyzing the average citation per item for countries with more than 10 publications, Ireland ranked first (10.19/item), New Zealand ranked second (9.5/item) followed by Finland (9.04/item). The citation rate can be assumed as an indicator for research quality. The ten most productive journals include three journals with the main focus telemedicine and another five with the main focus "Information/Informatics". In all subject categories examined for published items related to telemedicine, "Health Care Sciences & Services" ranked first by far. More than 36 % of all publications are assigned to this category, followed by "Medical Informatics" with 9.72 % and "Medicine, General & Internal" with 8.84 % of all publications. In summary it can be concluded that the data shows clearly a strong increase in research productivity. Using science citation analysis it can be assumed that there is a large rise in the interest in telemedicine studies.

    A constantly aging population leads to an increasing number of elderly patients. As a result, the treatment of chronic illnesses becomes a significant part of daily routine. Today's concepts in social services and healthcare require time consuming and barely cost-effective efforts for the special needs of geriatric care. The use of telemedicine offers a possible solution, because telemedical methods may help to realize improved monitoring systems for optimized and effective patient management. This report provides an overview of the scenarios and advantages of telemedicine in general. In addition, we provide information on practical experiences in a project on telemedical glaucoma management in Mecklenburg-Vorpommern.

    We started telemedicine projects from 1990 with a telepathology system within Tsukiji Campus of National Cancer Center. In 1994, we connected Tsukiji Campus and Kashiwa Campus by 6 Mbps optical fiber leased line using IP protocol for data transmission, for teleconference, telepathology, and teleradiology projects. We also started connection of regional cancer centers and are now forming a cancer center network of 14 cancer centers. We are at present organizing 130 teleconferences per year with an attendance of more than 16000 people as summary. We have also used a high-resolution image transferring system, such as SHD (2000 pixelsx2000 pixels resolution) system on one side, and an economical telemedicine system using JAVA and a WWW browser (NCC_image) on the other side. We think that providing information is another field of telemedicine. We began the experimental gopher and WWW service in 1993.

    This paper is a commentary on a project application of telemedicine to alleviate primary health care problems in Lundazi district in the Eastern province of Zambia. The project dubbed 'The Virtual Doctor Project' will use hard body vehicles fitted with satellite communication devices and modern medical equipment to deliver primary health care services to some of the neediest areas of the country. The relevance and importance of the project lies in the fact that these areas are hard-to-reach due to rugged natural terrain and have very limited telecommunications infrastructure. The lack of these and other basic services makes it difficult for medical personnel to settle in these areas, which leads to an acute shortage of medical personnel. We comment on this problem and how it is addressed by 'The Virtual Doctor Project', emphasizing that while the telemedicine concept is not new in sub-Saharan Africa, the combination of mobility and connectivity to service a number of villages 'on the go' is an important variation in the shift back to the 1978 Alma Ata principles of the United Nations World Health Organization [WHO]. This overview of the Virtual Doctor Project in Zambia provides insight into both the potential for ICT, and the problems and limitations that any "real-world" articulation of this technology must confront.

    e-health, the integration of telehealth technologies with the Internet and shared virtual reality could become a significant enabler of consumer health initiatives. In fact, they provide an increasingly accessible communication channel for a growing part of the population. In the past decade medical applications of virtual reality (VR) and telemedicine have been rapidly developing, and the technology has changed from a research curiosity to a commercially and clinically important area of medical informatics technology. The chapter details the characteristics of the Experiential Cognitive Therapy (ECT), an integrated inpatient/outpatient (4 weeks) and telemedicine approach (24 weeks) that tries to enhance the classical cognitive-behavioral method used in the treatment of eating disorders, through VR sessions and telemedicine support in the follow-up stage. Particularly, using VR and telemedicine, ECT is able to address body experience disturbances, interpersonal relationships, self efficacy and motivation to change, key issues for the development and maintenance of eating disorders that are somehow neglected by actual clinical guidelines.

    Nursing homes (NHs) provide care to a complex patient population and face the ongoing challenge of meeting resident needs for specialty care. A NH telemedicine care model could improve access to remote specialty providers. Little is known about provider interest in telemedicine for specialty consults in the NH setting. The goal of this study was to survey a national sample of NH physicians and advanced practice providers to document their views on telemedicine for providing specialty consults in the NH. We surveyed physician and advanced practice providers who attended the 2016 AMDA-The Society for Post-Acute and Long-Term Care Medicine Annual Conference about their likelihood of referral to and perceptions of a telemedicine program for providing specialty consults in the NH. We received surveys from 524 of the 1,274 conference attendees for a 41.1% response rate. Respondents expressed confidence in the ability of telemedicine to fill existing service gaps and provide appropriate, timelier care. Providers showed the highest level of interest in telemedicine for dermatology, geriatric psychiatry, and infectious disease. Only 13% of respondents indicated that telemedicine was available for use in one of their facilities. There appears to be unmet demand for telemedicine in NHs for providing specialty consults to residents. The responses of NH providers suggest support for the concept of telemedicine as a modality of care that can be used to offer specialty consults to NH residents.

    For many eServices, end-user trust is a crucial prerequisite for use. For the telemedicine context however, knowledge about the coming about and measurement of end-user trust is scarce. To develop and validate the PAtient Trust Assessment Tool (PATAT): a survey instrument to quantitatively assess patient trust in a telemedicine service. Informed by focus groups, we developed a survey that includes measurement scales for the following factors: trust in the care organization, care professional, treatment, and technology, as well as a scale that assesses a holistic view on trust in the telemedicine service. The survey was completed by 795 patients that use a telemedicine application to manage their anticoagulation treatment. Data were analyzed by means of Partial Least Squares Structural Equation Modeling (PLS-SEM). The measurement model yielded good to excellent quality measures, after the removal of one item. The causal model resulted in high explained variance (R 2 =0.68). Trust in healthcare professionals and the treatment had a small effect on overall trust, while trust in the technology displayed a large effect. Trust in the care organization did not result in a significant effect on overall trust. The PATAT is a valid means to assess patient trust in a telemedicine service and can be used to benchmark such a service or to elicit redesign input. Copyright © 2016 Elsevier Ireland Ltd.

    Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. First data on implementation of telemedicine for the diagnosis and treatment of acute myocardial infarction date from more than 10 years ago. Telemedicine has a potential broad application to the cardiovascular disease continuum and in many branches of cardiology, at least including heart failure, ischemic heart disease and arrhythmias. Telemedicine might have an important role as part of a strategy for the delivery of effective health care for patients with cardiovascular disease. In this document the Working Group on Telecardiology and Informatics of the Italian Society of Cardiology intends to remark some key-points regarding potential benefit achievable with the implementation of telemedicine support in the continuum of cardiovascular disease.

    2010-08-01

    Full Text Available Neurological facilities are traditionally centred in academic hospitals and often far away from the patients’ living area. Both, the transfer of patients to remote hospitals and inpatient treatment are associated with high energy consumption. Numbers of patients with neurological diseases are expected to increase along with the demographical changes and the environmental impact of neurological treatment should become a target for health policy, therefore. Positive effects have been demonstrated for the use of telemedicine by improving inpatient treatment in local community hospitals or avoiding hospital admissions via monitoring of complex diseases in outpatient settings. We discuss the potentials of telemedicine in the field of in- and outpatient neurological care as well as the need for more scientific evaluation on environmental impacts.

    The opinions of 110 emergency nurse practitioners (ENPs) practising telemedicine in 11 British minor injury units were sought using a questionnaire. There were 90 respondents (82%). The respondents thought that, since telemedicine had been introduced, they had become more open to change (96%) and more ready to grasp opportunities (93%). They considered that they were more keen to learn new things (99%) and were better disposed to teaching others (90%). They adopted a more advisory and supportive role (80%), found the work environment more varied (83%) and were well disposed to teamwork (64%). The power balance with doctors had changed (86%) and doctors indulged in dialogue rather than direction (69%). The results suggest that although changes have started in the workplace, they have not been as dramatic as a previous study of patients had predicted.

    Communication links are the lifelines for telemedicine practice. Various terrestrial and satellite media can be used; however, each has its own plus and minus side. The current study was designed to evaluate three types of telecommunication media used for telemedical videoconference at the Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow Telemedicine program over a period of 20 months. The evaluation was based on analysis of technical parameters recorded in a prescribed proforma designed for the study purpose and maintained prospectively after completion of each event. Only technical issues were addressed. At the end of the study period, analysis of data revealed that leased line-based terrestrial Internet Protocol (IP) was better than Sky IP. Integrated Services Digital Network media were found technically less acceptable for telemedical videoconference.

    2012-04-01

    Full Text Available Background: Eighty-five per cent of the Ethiopian population lives in remote areas, without access to modern health services. The limited health care budget, chronic shortage of health care workers and lack of incentives to retain those in remote areas further jeopardize the national health care delivery system. Recently, the application of information communication technology (ICT to health care delivery and the use of telemedicine have raised hopes.Objective: This paper analyzes the challenges, failures and successes encountered in setting-up and implementing a telemedicine program in Ethiopia and provides possible recommendations for developing telemedicine strategies in countries with limited resources.Design: Ten sites in Ethiopia were selected to participate in this pilot between 2004 and 2006 and twenty physicians, two per site, were trained in the use of a store and forward telemedicine system, using a dial-up internet connection. Teledermatology, teleradiology and telepathology were the chosen disciplines for the electronic referrals, across the selected ten sites.Results: Telemedicine implementation does not depend only on technological factors, rather on e-government readiness, enabling policies, multisectoral involvement and capacity building processes. There is no perfect ‘one size fits all’ technology and the use of combined interoperable applications, according to the local context, is highly recommended.Conclusions: Telemedicine is still in a premature phase of development in Ethiopia and other sub-Saharan African countries, and it remains difficult to talk objectively about measurable impact of its use, even though it has demonstrated practical applicability beyond reasonable doubts.

    2015-01-01

    Full Text Available Background. Telemedicine can be defined as the use of electronic media for transmission of information and medical data from one site to another. The objective of this study is to demonstrate an experience of telemedicine in plastic surgery. Methods. 32 plastic surgeons received a link with password for real-time streaming of a surgery. At the end of the procedure, the surgeons attending the procedure by the Internet answered five questions. The results were analyzed with descriptive statistics. Results. 27 plastic surgeons attended the online procedure in real-time. 96.3% considered the access to the website as good or excellent and 3.7% considered it bad. 14.8% reported that the transmission was bad and 85.2% considered the quality of transmission as good or excellent. 96.3% classified the live broadcasting as a good or excellent learning experience and 3.7% considered it a bad experience. 92.6% reported feeling able to perform this surgery after watching the demo and 7.4% did not feel able. 100% of participants said they would like to participate in other surgical demonstrations over the Internet. Conclusion. We conclude that the use of telemedicine can provide more access to education and medical research, for plastic surgeons looking for medical education from distant regions.

    ENGLISH ABSTRACT: For more than a decade, the South African National Department of Health (DoH has recognised the potential benefit of information and communication technology (ICT in the delivery of health care to rural areas. Despite generous funding and proven technology, not many telemedicine systems have proved sustainable after the pilot phase. The purpose of this paper is to develop a maturity model that can be implemented to measure and manage the capability of a health system, for use in the delivery of sustainable health care after the pilot phase of a telemedicine project. The validity of the telemedicine maturity model (TMMM is tested within the context of the South African public health sector.

    2017-01-01

    The use of telemonitoring and telemedicine is a relatively new but quickly developing area in medicine. As new digital tools and applications are being created and used to manage medical conditions such as heart failure, many implications require close consideration and further study, including the effectiveness and safety of these telemonitoring tools in diagnosing, treating and managing heart failure compared to traditional face-to-face doctor–patient interaction. When compared to multidisciplinary intervention programs which are frequently hindered by economic, geographic and bureaucratic barriers, non-invasive remote monitoring could be a solution to support and promote the care of patients over time. Therefore it is crucial to identify the most relevant biological parameters to monitor, which heart failure sub-populations may gain real benefits from telehealth interventions and in which specific healthcare subsets these interventions should be implemented in order to maximise value.

    Full Text Available There is a growing need worldwide to take medical care to distant locations far from the main urban centers, particularly to rural areas. Furthermore, there is the ethical imperative to provide equal access to medical care to all patients, regardless of their place of residence, so as to satisfy an increasingly demanding population. A widespread problem, from which cardiology is not excepted, is the insufficient number of specialists and their uneven distribution. The upsurge in information and communications technology has made available a large collection of tools, mainly computers, smartphones, e-mail, and the Internet, to name just a few, to meet the needs of communication between individuals and organizations. This article defines telemedicine and describes its application in the practice of cardiology and its impact in Chile.

    Full Text Available Background/Aim. In the last twenty years significant advances have been made in the fields of information and telecommunication technology in health care applications, with a positive impact on the health care practice. The need for remote diagnosis and planning of interventions is of special importance in military health care, and health management of immobile persons, and those with special needs. In cases such as these, availability of specialist health care is mainly limited by geographic and financial factors. The aim of this study was to investigate practical usability of telemedicine approaches in everyday management of oral surgery patients in terms of reliability of established diagnosis and indications for oral surgery treatment of the third molars. Methods. Our experimental randomized study enrolled 432 randomly selected patients of both genders, aged 20 to 87 years, undergoing panoramic radiography for some reason in the Centre for Dental Radiography in Belgrade. In addition to radiography, photographs of the face and mouth cavity were taken. These images were uploaded to the web server specially dedicated to the study purposes, and then transmitted to teledentists, i.e. oral surgeons, who made remote diagnoses. Diagnostic agreement was determined by way of the Cohen's kappa coefficient, and diagnostic sensitivity (SE, specificity (SP, and effectiveness (EFF were also established. Statistical significance was determined and comparisons performed by using the z-test, and testing of non-parametric characteristics by using the McNemar's χ2 test for p = 0.05 significance cut-off. Results. The results obtained by analyzed images and diagnostic assessment of the clinical diagnosis (kappa = 0.99, SE = 99%, SP = 99%, EFF = 99%, for 95% CI indicate an almost complete diagnostic agreement.

    2001-01-01

    The organizational consequences of telemedicine have frequently been mentioned in the telemedicine community, but there are few empirical studies. A study was therefore carried out of what happens in organizations when telemedicine is implemented. Qualitative interviews were undertaken with 30 persons working in teledermatology, telepsychiatry, a telepathology frozen-section service and tele-otolaryngology. Almost all respondents reported numerous organizational changes, some important. Changes in work processes were the most common. Examples of the organizational consequences of telemedicine were organizational restructuring, new organizational units, changed mechanisms for internal coordination, different flows of patients through the health-care system, improved coordination of care, new job descriptions, relocation of the place of work, employment of personnel living far away from the workplace, effects on employees not directly involved in telemedicine, sharing of experiences, minor staffing changes, clinical teamwork independent of co-location, administrative meetings arranged by telemedicine, merger of organizations independent of location, less travel by staff (and patients), a possible beneficial effect on the quality of care, and limited opposition to the adoption of the technology. Telemedicine may be important in the future organization of the disciplines studied and in health-care generally. The infrastructure of electronic networks may play an important role for organizations as the volume of telemedicine activity increases and economies of scale are realized.

    2016-03-01

    The number of patients with complications associated with chronic diseases increases with the ageing population. In particular, complex chronic wounds raise the re-admission rate in hospitals. In this context, the implementation of a telemedicine application in Basse-Normandie, France, contributes to reduce hospital stays and transport. This application requires a new collaboration among general practitioners, private duty nurses and the hospital staff. However, the main constraint mentioned by the users of this system is the lack of interoperability between the information system of this application and various partners' information systems. To improve medical data exchanges, the authors propose a new implementation based on the introduction of interoperable clinical documents and a digital document repository for managing the sharing of the documents between the telemedicine application users. They then show that this technical solution is suitable for any telemedicine application and any document sharing system in a healthcare facility or network.

  14. Content Aware Burst Assembly - Supporting Telesurgery and Telemedicine in Optical Burst Switching Networks

    Directory of Open Access Journals (Sweden)

    Henry Orosco

    2010-08-01

    Full Text Available The emerging Telemedicine and Telesurgery technologies allow patients to share medical experts remotely through communication networks. However, network bandwidth, network latency and jitter (variation of latency, are the obstacles to the widespread use of this technology remotely. Optical Burst Switching (OBS networks greatly expand network bandwidth in existing network infrastructure by utilizing multiple DWDM channels within a single fiber, enabling high bandwidth applications. However, the burst assembly process in OBS networks introduces latency and jitter, making it unsuitable for high bandwidth, latency sensitive applications such as telesurgery and telemedicine. In this paper, we propose a content aware burst assembly scheme which dynamically adjusts the burst assembly parameters based on the content being assembled. The proposed content aware burst assembly minimizes the latency and jitter within a video frame, as well as across the left-view and right-view frames for 3D vision generation. Simulation results have shown that the proposed scheme can effectively reduce the latency and jitter experienced by video streams, making OBS a promising candidate for supporting telesurgery and telemedicine applications.

    Advances in technology have expanded telemedicine opportunities covering medical practice, research, and education. This is of particular importance in movement disorders (MDs), where the combination of disease progression, mobility limitations, and the sparse distribution of MD specialists increase the difficulty to access. In this review, we discuss the prospects, challenges, and strategies for telemedicine in MDs. Telemedicine for MDs has been mainly evaluated in Parkinson's disease (PD) and compared to in-office care is cost-effective with similar clinical care, despite the barriers to engagement. However, particular groups including pediatric patients, rare MDs, and the use of telemedicine in underserved areas need further research. Interdisciplinary telemedicine and tele-education for MDs are feasible, provide similar care, and reduce travel costs and travel time compared to in-person visits. These benefits have been mainly demonstrated for PD but serve as a model for further validation in other movement disorders.

Review of the published medical literature, governmental documents, and opinions of experts from the Society of Critical Care Medicine ICU Telemedicine Committee. Formal ICU telemedicine programs now support 11% of nonfederal hospital critically ill adult patients. There is increasingly robust evidence of association with lower ICU (0.79; 95% CI, 0.65-0.96) and hospital mortality (0.83; 95% CI, 0.73-0.94) and shorter ICU (-0.62 d; 95% CI, -1.21 to -0.04 d) and hospital (-1.26 d; 95% CI, -2.49 to -0.03 d) length of stay. Physicians in training report experiences with telemedicine intensivists that are positive and increased patient safety. Early studies suggest that implementation of ICU telemedicine programs has been associated with lower numbers of malpractice claims and costs. The requirements for Medicare reimbursement and states with legislation addressing providing professional services by telemedicine are detailed. The inclusion of an ICU telemedicine program as a major part of their critical care delivery paradigm has been implemented for 11% of critically ill U.S. adults as a solution for the problem of access to adult critical care services. Implementation of an ICU telemedicine program is one practical way to increase access and reduce mortality as well as length of stay. ICU telemedicine research including comparative effectiveness studies is urgently needed.

    Telemedicine applications aim to address variance in clinical outcomes and increase access to specialist expertise. Despite widespread implementation, there is little robust evidence about cost-effectiveness, clinical benefits, and impact on quality and safety of critical care telemedicine. The primary objective was to determine the impact of critical care telemedicine (with clinical decision support available 24/7) on intensive care unit (ICU) and hospital mortality and length of stay in adults and children. The secondary objectives included staff and patient experience, costs, protocol adherence, and adverse events. Data sources included MEDLINE, EMBASE, CINAHL, Cochrane Library databases, Health Technology Assessment Database, Web of Science, OpenGrey, OpenDOAR, and the HMIC through to December 2015. Randomised controlled trials and quasi-experimental studies were eligible for inclusion. Eligible studies reported on differences between groups using the telemedicine intervention and standard care. Two review authors screened abstracts and assessed potentially eligible studies using Cochrane guidance. Two controlled before-after studies met the inclusion criteria. Both were assessed as high risk of bias. Meta-analysis was not possible as we were unable to disaggregate data between the two studies. One study used a non-randomised stepped-wedge design in seven ICUs. Hospital mortality was the primary outcome which showed a reduction from 13.6 % (CI, 11.9-15.4 %) to 11.8 % (CI, 10.9-12.8 %) during the intervention period with an adjusted odds ratio (OR) of 0.40 (95 % CI, 0.31-0.52; p = .005). The second study used a non-randomised, unblinded, pre-/post-assessment of telemedicine interventions in 56 adult ICUs. Hospital mortality (primary outcome) reduced from 11 to 10 % (adjusted hazard ratio (HR) = 0.84; CI, 0.78-0.89; p = review highlights the poor methodological quality of most studies investigating critical care telemedicine.

    One of the most powerful tools available for telemedicine is a multimedia medical record accessible over a wide area and simultaneously editable by multiple physicians. The ability to do this through an intuitive interface linking multiple distributed data repositories while maintaining full data integrity is a fundamental enabling technology in healthcare. The author discusses the role of distributed object technology using CORBA in providing this capability including an example of such a system (TeleMed) which can be accessed through the World Wide Web. Issues of security, scalability, data integrity, and useability are emphasized.

    This paper introduces a telemedicine innovation network and reports its implementation in Tehran University of Medical Sciences. The required conditions for the development of future projects in the field of telemedicine are also discussed; such projects should be based on the common needs and opportunities in the areas of healthcare, education, and technology. The development of the telemedicine innovation network in Tehran University of Medical Sciences was carried out in two phases: identifying the beneficiaries of telemedicine, and codification of the innovation network memorandum; and brainstorming of three workgroup members, and completion and clustering ideas. The present study employed a qualitative survey by using brain storming method. Thus, the ideas of the innovation network members were gathered, and by using Freeplane software, all of them were clustered and innovation projects were defined. In the services workgroup, 87 and 25 ideas were confirmed in phase 1 and phase 2, respectively. In the education workgroup, 8 new programs in the areas of telemedicine, tele-education and teleconsultation were codified. In the technology workgroup, 101 and 11 ideas were registered in phase 1 and phase 2, respectively. Today, innovation is considered a major infrastructural element of any change or progress. Thus, the successful implementation of a telemedicine project not only needs funding, human resources, and full equipment. It also requires the use of innovation models to cover several different aspects of change and progress. The results of the study can provide a basis for the implementation of future telemedicine projects using new participatory, creative, and innovative models.

    Little is known either about how telemedicine changes the job situation or about how the working environment might be improved for those involved in telemedicine. To investigate these issues, qualitative interviews were carried out with 30 people in Norway working with telepsychiatry (12 respondents), teledermatology (six respondents), a telepathology frozen-section service (10 respondents) and tele-otolaryngology (two respondents). The median annual number of remote consultations in telepsychiatry was nine, in teledermatology 81 and in the telepathology frozen-section service nine. The positive aspects of working with telemedicine included less travelling, which gave more time for other work, less need to travel in poor weather, new contacts, an increased sense of professional security (because support was readily available) and the satisfaction of seeing partners in communication. At its present volume, telemedicine generally fits into daily work patterns quite well. Problems do occur, but they can be solved by appropriate organizational measures. Long-term scheduling of telemedical sessions may be important. Many telemedicine workers want to have the equipment in their own office. Working with telemedicine can be tiring and those interviewed wanted to limit the number of hours per week. A solution may be to use large clinics, such as university clinics, where the telemedical work could be distributed between several specialists. Large telemedicine clinics with a full-time dedicated staff would need careful consideration of working practices.

    The American Telemedicine Association (ATA) held the Global Forum on Telemedicine: Connecting the World Through Partnerships in September 2007 with sponsorship by the Telemedicine and Advanced Technology Research Center (TATRC), U.S. Army Medical Research and Materiel Command (USAMRMC). The goal was to bring together key stakeholders in global healthcare outreach to explore a flexible framework and sustainable business model that can leverage telemedicine and information technology (IT) to expand healthcare services internationally. Dr. Hon S. Pak, President of the ATA, opened the forum with a call for collaboration and partnership, and encouraged continued international dialogue to create a framework that leverages the telemedicine community to improve global disparity in healthcare. Keynote addresses included speakers from the World Health Organization (UN) and United Nations (UN) Global Alliance for Information and Communities Technologies and Development (GAID). Presentations from 15 government and nongovernment aid organizations (NGOs) and 12 international programs covered 5 key areas: (1) NGO perspective; (2) governmental/military programs; (3) financial sustainability; (4) disaster response; and (5) emerging opportunities. The forum resulted in an International Roadmap for Action that was developed by the authors based on the presentations and interactions from the 335 attendees and establishing a set of priorities and actions to improve healthcare using telemedicine and IT. Recommendations include: (1) continued dialogue in creating a telemedicine framework; (2) identification and leverage of resources; (3) provision of education to funding organization and expand training programs to build competency in the healthcare workforce; (4) alignment of international policy to support integration of telemedicine into country plans and support cross-country partnerships; (5) development of communications infrastructure; and (6) integration of telemedicine into

    Recent years have seen the development of two significant trends namely: the adoption of some Traditional Chinese Medicine Practices into mainstream Allopathic Western Medicine and the advent of the internet and broad band networks leading to an increased interest in the use of Telemedicine to deliver medical services. In this book, we see the convergence of these two trends leading to a semantically-based TCM Telemedicine system that utilizes an ontology to provide sharable knowledge in the TCM realm to achieve this. The underpinning research required the development of a three-layer architecture and an Ontology of the TCM knowledge. As TCM knowledge like all medical knowledge is not frozen in time it was important to develop an approach that would allow evolution of the Ontology when new evidence became available. In order for the system to be practically grounded it was important to work with an industry partner PuraPharm Group/HerbMiners Informatics Limited. This partnership was initiated through Professo...

    The VitalPoll Telemedicine System (VTS) was designed and developed for wireless home healthcare. The aims of this study were: to design the architecture and communication methods for a telemedicine system; to implement a physiologic routing hub to collect data from different medical devices and sensors; and to evaluate the feasibility of this system for applications in wireless home healthcare. The VTS was built using Bluetooth wireless and Internet technologies with client/server architecture. Several medical devices, which acquire vital signs, such as real-time electrocardiogram signals, heart rate, body temperature, and activity (physical motion), were integrated into the VTS. Medical information and data were transmitted over short-range interface (USB, RS232), wireless communication, and the Internet. The medical results were stored in a database and presented using a web browser. The patient's vital signals can be collected, transmitted, and displayed in real time by the VTS. The experiments verified no data loss during Bluetooth and Internet communication. Bluetooth and the Internet provide enough bandwidth channels to tranmit these vital signs. The experimental results show that VTS may be suitable for a practical telemedicine system in home healthcare.

    To evaluate feasibility and impact of telemedicine for remote parent participation in pediatric intensive care unit (PICU) rounds when parents are unable to be present at their child's bedside. Parents of patients admitted to a 14-bed PICU were approached, and those unable to attend rounds were eligible subjects. Nurse and physician caregivers were also surveyed. Parents received an iPad (Apple Inc, Cupertino, California) with an application enabling audio-video connectivity with the care team. At a predetermined time for bedside rounds with the PICU team, parents entered a virtual meeting room to participate. Following each telemedicine encounter, participants (parent, physician, nurse) completed a brief survey rating satisfaction (0?=?not satisfied, 10?=?completely satisfied) and disruption (0?=?no disruption at all, 10?=?very disruptive). A total of 153 surveys were completed following 51 telemedicine encounters involving 13 patients. Parents of enrolled patients cited work demands (62%), care for other dependents (46%), and transportation difficulties (31%) as reasons for study participation. The median levels of satisfaction and disruption were 10 (range 5-10) and 0 (range 0-5), respectively. All parents reported that telemedicine encounters had a positive effect on their level of reassurance regarding their child's care and improved communication with the care team. This proof-of-concept study indicates that remote parent participation in PICU rounds is feasible, enhances parent-provider communication, and offers parents reassurance. Providers reported a high level of satisfaction with minimal disruption. Technological advancements to streamline teleconferencing workflow are needed to ensure program sustainability.

    The objective of this work was to provide computer and telecommunications skill training for paraplegics using a telemedicine training center in a curriculum that would support connectivity and offer new skills for career applications in the rehabilitation phase and beyond. This was a hospital-based, cross-sectional study. The study was conducted from October 10, 2005 to May 10, 2006 in the hospitals of Rawalpindi Medical College and the Melody Rehabilitation Center, Rawalpindi, Pakistan. These centers provided care for casualties of the October 2005 earthquake in Pakistan. One hundred and ninety four (194) paraplegics were admitted to Rawalpindi Medical College allied hospitals after injuries in the rural mountains near the epicenter. Surveys assessed the education level of the patients, and a sample of 12 patients was enrolled in computer training classes. Of the 194 patients, 144 were female and 50 were male. The majority, 78% (151) were 16-39 years of age. Although only 60% were literate, the overall literacy rate of Pakistan is just 48.7%. Telephone service at home was available after discharge for 40% of patients. Only 8% of patients had basic computer skills. All patients participated in the survey and sought to take the course. All the enrolled patients demonstrated full competency in the skills taught. The social disruption of disaster plus the new challenge of a neurological deficit in paraplegia did not deter a remarkable number of patients from a rural area from engaging in computer and telemedicine training. This study demonstrated the feasibility of educating rural paraplegics in computer skills for telemedicine. The telemedicine training center was used for this task without special equipment or personnel, thereby increasing the utilization of the facility.

    The quality and performance of several videoconferencing applications (apps) tested on iOS (Apple, Cupertino, CA) and Android (Google, Mountain View, CA) mobile platforms using Wi-Fi (802.11), third-generation (3G), and fourth-generation (4G) cellular networks are described. The tests were done to determine how well apps perform compared with videoconferencing software installed on computers or with more traditional videoconferencing using dedicated hardware. The rationale for app assessment and the testing methodology are described. Findings are discussed in relation to operating system platform (iOS or Android) for which the apps were designed and the type of network (Wi-Fi, 3G, or 4G) used. The platform, network, and apps interact, and it is impossible to discuss videoconferencing experienced on mobile devices in relation to one of these factors without referencing the others. Apps for mobile devices can vary significantly from other videoconferencing software or hardware. App performance increased over the testing period due to improvements in network infrastructure and how apps manage bandwidth.

    The feasibility of telemedicine in diagnosing and treating nonacute headaches, such as primary headaches (migraine and tension-type) and medication-overuse headaches has not been previously investigated. By eliminating the need of travel to specialists, telemedicine may offer significant time and money savings. Our objective was to estimate the acceptance of telemedicine and investigate the feasibility and cost savings of telemedicine consultations in diagnosing and treating nonacute headaches. From September 2012 to March 2015, nonacute headache patients from Northern Norway who were referred to neurologists through an electronic application system were consecutively screened and randomized to participate in either telemedicine or traditional specialist visits. All patients were consulted by two neurologists at the neurological department in Tromsø University Hospital. Feasibility outcomes were compared between telemedicine and traditional groups. Baseline characteristics and costs were then compared between rural and urban patients. Travel costs were calculated by using the probabilistic method of the Norwegian traveling agency: the cheapest means of public transport for each study participant. Loss of pay was calculated based on the Norwegian full-time employee's average salary: 3.5 hours spent on travel and consultation=one day's salary. Distance and time spent on travel were estimated by using Google Maps. Of 557 headache patients screened, 479 were found eligible and 402 accepted telemedicine participation (83.9%, 402/479) and were included in the final analyses. Of these, 202 received traditional specialist consultations and 200 received telemedicine. All patients in the telemedicine group were satisfied with the video quality, and 198 (99%, 198/200) were satisfied with the sound quality. The baseline characteristics as well as headache diagnostics and follow-up appointments, and the investigation, advice, and prescription practices were not statistically

Positive effects on glycemic control were noted with studies examining telemedicine, with a mean reduction of 0.18% at the end of intervention. Studies with longer duration (>6 months who had recruited patients with a higher baseline HbA1c (≥9% were associated with larger effects. Telemedicine interventions that involve individualized assessments, audit with feedback and skill building were also more effective in improving glycemic control. However, no benefits were observed on blood pressure, lipids, weight, quality of life, and adverse events.Conclusions and Relevance: There is insufficient evidence to support telemedicine use for glycemic

    2008-01-01

    At what point does an international telemedicine transaction create a sufficient commercial nexus to allow one country the authority to impose its laws on a foreign telemedicine providers? Some light on this matter was shed by the US case of Hageseth versus Superior Court. The authority for extraterritorial jurisdiction is found in the US Constitution, which requires the states to cooperate in matters of law enforcement. Similar cooperation from foreign nations cannot be expected. Unless a defendant is charged with a capital offence, nations are rarely willing to extradite their citizens. As the unlicensed practice of medicine is not a capital offence, it is unlikely that an unlicensed telemedicine provider would be extradited to the US. Because low-volume unlicensed offshore telemedicine providers are unlikely to be extradited or to be subject to trade sanctions, they may be able to operate beyond the law.

    2010-01-01

    Full Text Available A typical telemedicine system involves a small set of hospitals providing remote healthcare services to a small section of the society using dedicated nodal centers. However, in developing nations like India where majority live in rural areas that lack specialist care, we envision the need for much larger Internet-based telemedicine systems that would enable a large pool of doctors and hospitals to collectively provide healthcare services to entire populations. We propose a scalable, Internet-based P2P architecture for telemedicine integrating multiple hospitals, mobile medical specialists, and rural mobile units. This system, based on the store and forward model, features a distributed context-aware scheduler for providing timely and location-aware telemedicine services. Other features like zone-based overlay structure and persistent object space abstraction make the system efficient and easy to use. Lastly, the system uses the existing internet infrastructure and supports mobility at doctor and patient ends.

    The U.S. Navy is considering the installation of telemedicine equipment on more than 300 ships. Besides improving the quality of care, benefits would arise from avoiding medical evacuations (MEDEVACs) and returning patients to work more quickly. Because telemedicine has not yet been fully implemented by the Navy, we relied on projections of anticipated savings and costs, rather than actual expenditures, to determine cost-effectiveness. To determine the demand for telemedicine and the cost-effectiveness of various technologies (telephone and fax, e-mail and Internet, video teleconferencing (VTC), teleradiology, and diagnostic instruments), as well as their bandwidth requirements. A panel of Navy medical experts with telemedicine experience reviewed a representative sample of patient visits collected over a 1-year period and estimated the man-day savings and quality-of-care enhancements that might have occurred had telemedicine technologies been available. The savings from potentially avoiding MEDEVACs was estimated from a survey of ships' medical staff. These sample estimates were then projected to the medical workload of the entire fleet. Off-the-shelf telemedicine equipment prices were combined with installation, maintenance, training, and communication costs to obtain the lifecycle costs of the technology. If telemedicine were available to the fleet, ship medical staffs would initiate nearly 19, 000 consults in a year-7% of all patient visits. Telemedicine would enhance quality of care in two-thirds of these consults. Seventeen percent of the MEDEVACs would be preventable with telemedicine (representing 155,000 travel miles), with a savings of $4400 per MEDEVAC. If the ship's communication capabilities were available, e-mail and Internet and telephone and fax would be cost-effective on all ships (including small ships and submarines). Video teleconferencing would be cost-effective on large ships (aircraft carriers and amphibious) only. Teleradiology would be cost

    Telemedicine can be defined as the use of electronic media for the transmission of clinical data and information from one location to another using information technology and telecommunication in order to provide immediate clinical health care at long distances. This new approach can involve specialized medical service centers in the oil production at great distances from the offshore installations in Brazil. The importance of the right health diagnosis, taken at the proper time, will make a serious difference in the facilities, which will be located around 300 km offshore. This paper presents an overview of telemedicine and its different applications, comparing them according to level of maturity and applicability. Important results from a case study in a fixed oil platform are analyzed. At the end of this work, the strategy of telemedicine implementation in a Brazilian petroleum operator is discussed.

    This article presents the scientific evidence for the merits of telemedicine interventions in primary care. Although there is no uniform and consistent definition of primary care, most agree that it occupies a central role in the healthcare system as first contact for patients seeking care, as well as gatekeeper and coordinator of care. It enables and supports patient-centered care, the medical home, managed care, accountable care, and population health. Increasing concerns about sustainability and the anticipated shortages of primary care physicians have sparked interest in exploring the potential of telemedicine in addressing many of the challenges facing primary care in the United States and the world. The findings are based on a systematic review of scientific studies published from 2005 through 2015. The initial search yielded 2,308 articles, with 86 meeting the inclusion criteria. Evidence is organized and evaluated according to feasibility/acceptance, intermediate outcomes, health outcomes, and cost. The majority of studies support the feasibility/acceptance of telemedicine for use in primary care, although it varies significantly by demographic variables, such as gender, age, and socioeconomic status, and telemedicine has often been found more acceptable by patients than healthcare providers. Outcomes data are limited but overall suggest that telemedicine interventions are generally at least as effective as traditional care. Cost analyses vary, but telemedicine in primary care is increasingly demonstrated to be cost-effective. Telemedicine has significant potential to address many of the challenges facing primary care in today's healthcare environment. Challenges still remain in validating its impact on clinical outcomes with scientific rigor, as well as in standardizing methods to assess cost, but patient and provider acceptance is increasingly making telemedicine a viable and integral component of primary care around the world.

    The stethoscope is a medical acoustic device which is used to auscultate internal body sounds, mainly the heart and lungs. A digital stethoscope overcomes the limitations of a conventional stethoscope as the sound data is transformed into electrical signals which can be amplified, stored, replayed and, more importantly, sent for an expert opinion, making it very useful in telemedicine. With the above in view, a low cost digital stethoscope has been developed which is interfaceble with mobile communication devices. In this instrument sounds from various locations can be captured with the help of an electret condenser microphone. Captured sound is filtered, amplified and processed digitally using an adaptive line enhancement technique to obtain audible and distinct heart sounds.

    ICT opens new possibilities to health care and practice of medicine, but carries some inherent risks as well. Based on a study conducted by the CPME representing European doctors current telemedical practices and difficulties encountered by doctors are reported and next important steps are proposed. An European e-Health Highway should be built and obligatory standards for it and for all software used in the health care should be urgently fixed. The medical profession should take care of practical guidelines for doctors, and authorities should agree on international collaboration to supervise the practice of medicine over the net. Telemedicine should be a normal part of the national healthcare systems, and telemedical services should be reimbursed as any other medical services.

    Children with care for acute illness available through the Health-e-Access telemedicine model at childcare and schools were previously found to have 22% less emergency department (ED) use than counterparts without this service, but they also had 24% greater acute care use overall. We assessed the hypothesis that increased utilization reflected improved access among impoverished inner-city children to a level experienced by more affluent suburban children. This observational study compared utilization among children without and with telemedicine access, beginning in 1993, ending in 2007, and based on 84,287 child-months of billing claims-based observation. Health-e-Access Telemedicine was initiated in stepwise manner over 187 study-months among 74 access sites (childcare, schools, community centers), beginning in month 105. Children dwelled in inner city, rest-of-city Rochester, NY, or in surrounding suburbs. Rate of total acute care visits (office, ED, telemedicine) was measured as visits per 100 child-years. Observed utilization rates were adjusted in multivariate analysis for age, sex, insurance type, and season of year. When both suburban and inner-city children lacked telemedicine access, overall acute illness visits were 75% greater among suburban than inner-city children (suburban:inner-city rate ratio 1.75, p Health-e-Access Telemedicine redressed socioeconomic disparities in acute care access in the Rochester area, thus contributing to a more equitable community.

    To compare the frequency of physician-related medication errors among seriously ill and injured children receiving telemedicine consultations, similar children receiving telephone consultations, and similar children receiving no consultations in rural emergency departments (EDs). We conducted retrospective chart reviews on seriously ill and injured children presenting to 8 rural EDs with access to pediatric critical care physicians from an academic children's hospital. Physician-related ED medication errors were independently identified by 2 pediatric pharmacists by using a previously published instrument. The unit of analysis was medication administered. The association of telemedicine consultations with ED medication errors was modeled by using hierarchical logistic regression adjusting for covariates (age, risk of admission, year of consultation, and hospital) and clustering at the patient level. Among the 234 patients in the study, 73 received telemedicine consultations, 85 received telephone consultations, and 76 received no specialist consultations. Medications for patients who received telemedicine consultations had significantly fewer physician-related errors than medications for patients who received telephone consultations or no consultations (3.4% vs. 10.8% and 12.5%, respectively; P medications for patients who received telemedicine consultations had a lower odds of physician-related errors than medications for patients who received telephone consultations (odds ratio: 0.19, P Pediatric critical care telemedicine consultations were associated with a significantly reduced risk of physician-related ED medication errors among seriously ill and injured children in rural EDs.

    This paper will cover definition and history of telemedicine, changes in medical paradigm and roll of telemedicine and roll of nano-technology for evolution of telemedicine. Hypothetically, telemedicine is distance communication for medical purpose and modern definition explains telemedicine as `a system of health care delivery in which physicians examine distant patients through the use of telecommunications technology. Medical service will change to personalized medicine based on gene information to prevent and manage diseases due to decrease of acute diseases, population aging and increase of prevalence in chronic diseases, which means current medical services based on manualized treatment for diseases will change to personalized medicine based on individual gene information. Also, international healthcare will be activated to provide high quality medical services with low cost using developed transportation. Moreover, hospital centered medical services will change to patients centered medical service due to increase of patient's rights. Development in sensor technology is required for telemedicine to be applied as basic infrastructure for medical services. Various researches in nano-biosensor field are conducted due to introduction of new technologies. However, most researches are in fundamental levels that requires more researches for stability and clinical usefulness. Nano technology is expected to achieve innovative development and define new criteria for disease prevention and management.

  7. Risk of Telemedicine Infeasibility: An Evidential Reasoning Approach

    2017-10-01

    Full Text Available The viability of a telemedicine system is the strength of its business continuity. Business continuity can only stand if the telemedicine system remains continuously feasible. This article studies telemedicine risk in terms of its feasibility on all its five components: economical, technical, social, operational, and legal/ethical. Any deficiencies in one or more of the feasibility components will affect the system business continuity risk and can lead to infeasibility and possible dissolution. The telemedicine computing environment is full of uncertainties and ambiguities and it just involves too much background knowledge that Bayesian theory cannot accommodate. Decision theory however offers a basic evidence-based multi-criteria decision mechanism that can tackle those decision problems treating both quantitative and qualitative criteria under various uncertainties including ignorance and randomness. We propose an evidential reasoning model to assess a telemedicine business continuity risk based on infeasibility. This business continuity risk is modelled using Dempster and Shafer Theory as the plausibility of infeasibility of the telemedicine system. A numerical example is provided to demonstrate the working of the proposed risk assessment model.

    Full Text Available The paper deals with a result of the network services development for the optodigital complex for telemedicine diagnostics. This complex is designed for laboratory and clinical tests in health care facilities. Composition of network services includes the following: a client application for database of diagnostic test, a web-service, a web interface, a video server and microimage processing server. Structure of these services makes it possible to combine set of software for transferring depersonalized medical data via the Internet and operating with optodigital devices included in the complex. Complex is consisted of three systems: micro-vision, endoscopic and network. The micro-vision system includes an automated digital microscope with two highly sensitive cameras which can be controlled remotely via the Internet. The endoscopic system gives the possibility to implement video broadcasting to remote users both during diagnostic tests and also off-line after tests. The network system is the core of the complex where network services and application software are functioning, intended for archiving, storage and providing access to the database of diagnostic tests. The following subjects are developed and tested for functional stability: states transfer protocol, commands transfer protocol and video-stream transfer protocol from automated digital microscope and video endoscope. These protocols can work in web browsers on modern mobile devices without additional software.

  9. Crossing the Telemedicine Chasm: Have the U.S. Barriers to Widespread Adoption of Telemedicine Been Significantly Reduced?

    2013-11-01

    Full Text Available Barriers have challenged widespread telemedicine adoption by health care organizations for 40 years. These barriers have been technological, financial, and legal and have also involved business strategy and human resources. The article canvasses recent trends—events and activities in each of these areas as well as US health reform activities that might help to break down these barriers. The key to telemedicine success in the future is to view it as an integral part of health care services and not as a stand-alone project. Telemedicine must move from experimental and separate to integrated and equivalent to other health services within health care organizations. Furthermore, telemedicine serves as vital connective tissue for expanding health care organization networks.

    The growth of technology based on internet protocol has affected on the informatics and automatic controls of medical fields. The aim of this study was to establish the telemedical educational system by developing the high quality image transfer using the DVTS (digital video transmission system) on the high-speed internet network. Using telemedicine, we were able to send surgical images not only to domestic areas but also to international area. Moreover, we could discuss the condition of surgical procedures in the operation room and seminar room. The Korean-Japan cable network (KJCN) was structured in the submarine between Busan and Fukuoka. On the other hand, the Korea advanced research network (KOREN) was used to connect between Busan and Seoul. To link the image between the Hanyang University Hospital in Seoul and Kyushu University Hospital in Japan, we started teleconference system and recorded image-streaming system with DVTS on the circumstance with IPv4 network. Two operative cases were transmitted successfully. We could keep enough bandwidth of 60 Mbps for two-line transmission. The quality of transmitted moving image had no frame loss with the rate 30 per second. The sound was also clear and the time delay was less than 0.3 sec. Our study has demonstrated the feasibility of domestic and international telemedicine. We have established an international medical network with high-quality video transmission over internet protocol. It is easy to perform, reliable, and also economical. Thus, it will be a promising tool in remote medicine for worldwide telemedical communication in the future.

    Full Text Available The medical system is facing a wide range of challenges nowadays due to changes that are taking place in the global healthcare systems. These challenges are represented mostly by economic constraints (spiraling costs, financial issues, but also, by the increased emphasis on accountability and transparency, changes that were made in the education field, the fact that the biomedical research keeps growing in what concerns the complexities of the specific studies etc. Also the new partnerships that were made in medical care systems and the great advances in IT industry suggest that a predominant paradigm shift is occurring. This needs a focus on interaction, collaboration and increased sharing of information and knowledge, all of these may is in turn be leading healthcare organizations to embrace the techniques of data mining in order to create and sustain optimal healthcare outcomes. Data mining is a domain of great importance nowadays as it provides advanced data analysis techniques for extracting the knowledge from the huge volumes of data collected and stored by every system of a daily basis. In the healthcare organizations data mining can provide valuable information for patient's diagnosis and treatment planning, customer relationship management, organization resources management or fraud detection. In this article we focus on describing the importance of data mining techniques and systems for healthcare organizations with a focus on developing and implementing telemedicine solution in order to improve the healthcare services provided to the patients. We provide architecture for integrating data mining techniques into telemedicine systems and also offer an overview on understanding and improving the implemented solution by using Business Process Management methods.

    Telecardiology holds great promise for Africa, from tele-echocardiography and tele-ECG s, to home monitoring and text messaging for medication adherence monitoring. The burden of disease is great and there is an extreme shortage of health professionals. Telemedicine can provide access to scarce specialist care, improve the quality of care in rural areas and reduce the need for rural patients to travel to seek medical attention. International cross border service can alleviate the shortage of doctors. But telecardiology, and telemedicine uptake in general, has been poor in Africa. Legal and ethical issues around local and cross border telemedicine have not been resolved. The literature was reviewed and obstacles to telemedicine in Africa and current telemedicine activities in Africa, are described. There are few sustained telemedicine services in Africa with the exception of tele-education. There is an expectation that mobile phones will facilitate a range of telemedicine activities in Africa. Africa needs telemedicine. © 2013.

    Rural areas in developing countries are characterized by lack of resources, low population density, and scarcity of communications infrastructure. These circumstances make it difficult to provide appropriate health-care services. This paper explains research results achieved by Enlace Hispano Americano de Salud – Hispano American Health Link (EHAS) and how they have contributed to improve healthcare in isolated areas of developing countries through the use of information and communication technologies (ICT). As the first step, EHAS always collaborates with public health systems to identify its communication and information needs. Based on the analysis of needs, EHAS does research on appropriate technologies to provide communication in each context and on information systems suited to needs of health personnel. In parallel, EHAS has worked to provide applications that, making use of the communications services installed, could improve the health-care services in these remote areas. In this line, solutions to improve epidemiological surveillance or to provide telemedicine services (like a digital stethoscope or a tele-microscopy system) have been developed. EHAS has also performed several researches trying to ensure the sustainability of their solutions and has summarized them in a Management Framework for Sustainable e-Healthcare Provision. Finally, the effort to spread acquired knowledge has crystallized in a book that details all the technologies and procedures previously mentioned. PMID:25360436

    Data are limited that establish the clinical reliability of telemedicine in evaluating children who are seriously ill. Evaluation of a seriously ill child poses a challenge in that telemedicine is primarily visual, without the ability to perform a "hands-on" physical examination. Previous studies evaluating observation in assessing febrile children and children in respiratory distress have validated observation as both predictive and reliable in detecting underlying illness. The purpose of this study was to determine the interobserver reliability of telemedicine observations, compared with bedside observations, in assessing febrile children and children in respiratory distress. Children 2 to 36 months old presenting with a fever were evaluated by using the Yale Observation Scale; patients aged 2 months to 18 years presenting with respiratory symptoms were evaluated by using the Respiratory Observation Checklist, a list of observational signs of respiratory distress derived from validated studies and developed specifically for the present study by the authors. Telemedicine communication used commercially available tablet devices that provided 2-way, live-streamed images with audio. A total of 132 febrile subjects were evaluated by using the Yale Observation Scale. Strong agreement (Pearson's correlation coefficient, 0.81) was found between bedside and telemedicine observers. A total of 145 subjects were evaluated by using the Respiratory Observation Checklist. Excellent agreement between bedside and telemedicine observers was found for the impression of respiratory distress (κ = .85) and good agreement (κ > .6) for the majority of the remaining components of the checklist. Telemedicine, using commercially available telecommunications equipment, is reliable in the assessment of febrile children and children with respiratory distress.

    Portable, telemedicine-friendly devices offer novel opportunity for screening and monitoring glaucoma in the remote and rural regions of the world. This study examines the effective combination of telemedicine-friendly screening devices for detection of glaucoma in relation with conventional, hospital-based devices. A total of 399 eyes were screened with telemedicine-friendly devices and conventional, hospital-based devices such as ophthalmoscope, tonometer and perimeter. Combination of age and family history of glaucoma alone has a sensitivity of 35.6% (specificity 94.2%, area under the curve 0.81, correctly classified 81.1%) and an addition of telemedicine-friendly or conventional visual field tests optimized the sensitivity to 91.1% (specificity 93.6%, area under the curve 0.95, correctly classified 93%). Analysis indicates good agreement between vertical cup-to-disc ratio by ophthalmoscopy and digital image reading. An addition of intraocular pressure test does not change sensitivity (35.6%) and specificity (94.2%). This study indicates that evaluations of cup-to-disc ratio and visual field, using telemedicine-friendly devices, are most useful tools in screening for glaucoma. When used together these devices may be an alternative for conventional glaucoma screenings.

    The Telemedicine Spacebridge, a satellite-mediated, audio-video-fax link between four United States and two Armenian and Russian medical centers, permitted remote American consultants to assist Armenian and Russian physicians in the management of medical problems following the December 1988 earthquake in Armenia and the June 1989 gas explosion near Ufa. During 12 weeks of operations, 247 Armenian and Russian and 175 American medical professionals participated in 34 half-day clinical conferences. A total of 209 patients were discussed, requiring expertise in 20 specialty areas. Telemedicine consultations resulted in altered diagnoses for 54, new diagnostic studies for 70, altered diagnostic processes for 47, and modified treatment plans for 47 of 185 Armenian patients presented. Simultaneous participation of several US medical centers was judged beneficial; quality of data transmission was judged excellent. These results suggest that interactive consultation by remote specialists can provide valuable assistance to on-site physicians and favorably influence clinical decisions in the aftermath of major disasters.

    Telemedicine has been proposed as one strategy to improve local trauma care and decrease disparities between rural and urban trauma outcomes. This study was conducted to describe the effect of telemedicine on management and clinical outcomes for trauma patients in North Dakota. Cohort study of adult (age ≥18 years) trauma patients treated in North Dakota Critical Access Hospital (CAH) Emergency Departments (EDs) from 2008 to 2014. Records were linked to a telemedicine network's call records, indicating whether telemedicine was available and/or used at the institution at the time of the care. Multivariable generalized estimating equations were developed to identify associations between telemedicine consultation and availability and outcomes such as transfer, timeliness of care, trauma imaging, and mortality. Of the 7,500 North Dakota trauma patients seen in CAH, telemedicine was consulted for 11% of patients in telemedicine-capable EDs and 4% of total trauma patients. Telemedicine utilization was independently associated with decreased initial ED length of stay (LOS) (30 min, 95% confidence interval [CI] 14-45 min) for transferred patients. Telemedicine availability was associated with an increase in the probability of interhospital transfer (adjusted odds ratio [aOR] 1.2, 95% CI 1.1-1.4). Telemedicine availability was associated with increased total ED LOS (15 min, 95% CI 10-21 min), and computed tomography scans (aOR 1.6, 95% CI 1.3-1.9). ED-based telemedicine consultation is requested for the most severely injured rural trauma patients. Telemedicine consultation was associated with more rapid interhospital transfer, and telemedicine availability is associated with increased radiography use and transfer. Future work should evaluate how telemedicine could target patients likely to benefit from telemedicine consultation.

    Telemedicine involves electronic communication between a physician in one location and a patient in another location to provide remote medical care. Ophthalmologists are increasingly employing telemedicine, particularly in retinal disease screening and monitoring. Telemedicine has been utilized to decrease barriers to care and yield greater patient satisfaction and lower costs, while maintaining high sensitivity and specificity. This review discusses common patient barriers to eye care, innovative approaches to retinal disease screening and monitoring using telemedicine, and eye care policy initiatives needed to enact large-scale telemedicine eye disease screening programs.

    Telemedicine (health-care delivery where physicians examine distant patients using telecommunications technologies) has been heralded as one of several possible solutions to some of the medical dilemmas that face many developing countries. In this study, we examine the current state of telemedicine in a developing country, India. Telemedicine has brought a plethora of benefits to the populace of India, especially those living in rural and remote areas (constituting about 70% of India's population). We discuss three Indian telemedicine implementation cases, consolidate lessons learned from the cases, and culminate with potential researchable critical success factors that account for the growth and modest successes of telemedicine in India. ?? 2005 IEEE.

    Introducing telemedicine into clinical practice has not been without difficulties. Within the framework of the European Union project "Health Optimum," telemedicine consultations with specialists at the Department of Oral & Maxillofacial Surgery at Uppsala University Hospital (Uppsala, Sweden) have been offered to dentists in the public dental health service. The aim is to streamline the consultation process, improve/develop the skills of the participating dentists and dental hygienists, and save time and money for patients, healthcare authorities, and society. Patient records are collected in a database for demonstration and discussion, and the system is also available for referrals. Both medical and dental photographs and x-rays are digitized in the same system. These can be viewed during telemedicine rounds and by the consultants at the hospital prior to a consultation. Secure, interactive conferencing software is used, which provides a quick, easy, and effective way to share video and data over the Internet. Both parties can demonstrate different parts of an image using a pointer or a drawing system. Conference phones are presently used for verbal communication. Ten patients were discussed during telemedicine rounds (3 males and 7 females), all of whom would normally have been referred to a specialist. As a result of the telemedicine round, 2 were referred to a specialist, whereas diagnoses were made for the other 8, and treatment was suggested. The dental health clinic could thus provide treatment without the need for referral to a consultant. The telemedicine system described here allows patient care to be provided rapidly and more economically. Future plans include "live" rounds using a videocamera, providing the possibility to relay real-time information about the intraoral situation. A camera is being developed and should preferably be permanently installed chair side.

    There are few telemedicine projects in Africa that have reached scale. One of the reasons proposed for this has been failure to assess health provider readiness for telemedicine prior to implementation. To assess health provider readiness for implementation and integration of telemedicine services at three levels of Uganda's health facilities, namely, a national referral hospital (NRH), regional referral hospitals (RRHs) and level 4 health centres (HC-IVs) and to investigate factors associated with readiness for telemedicine. A cross-sectional descriptive study was conducted at public healthcare facilities in Uganda. One RRH and HC-IV was identified from each of the Western, Eastern and Northern regions using a multistage random sampling technique. Mulago Hospital, which doubles as an RRH and HC-IV in the central region, was purposively identified for the study. After validation, a questionnaire was distributed for self-administration to senior administrators and doctors selected at the NRH, RRHs and HC-IVs. Data were analysed using bivariate associations between the outcome and the potential independent variables. In total, 114 healthcare workers completed the questionnaire. Of the respondents, 24 (21%) were from HC-IVs, 44 (39%) were from RRHs, and 46 (40%) from NRH. Doctors made up 45.8% (11) of respondents at HC-IVs, 59% (26) at RRHs, and 30.4% (14) at NRH. Administrators across all health facility levels were more likely to integrate telemedicine into the healthcare system than doctors (odd ratio = 1.39 [95% confidence interval = 0.38-4.95]). A significant association existed between the state of readiness and type of health facility, p technology type, reason for referral and frequency of electronic communication), the level of health facility and title or role of healthcare worker were found to have a significant statistical association with being ready to integrate telemedicine into the healthcare system.

    Full Text Available Introduction/Aim. The first written evidence of telemedicine dates back to the times of Sava Nemanjić (the end of 12th and the beginning of 13th century. Nowadays, the use of telemedicine in Serbia gains momentum, and the cause of this lies in the creation of a central telemedicine system XPA3 Online and the establishment of the Center for Telemedicine at the Faculty of Medicine, University of Priština/Kosovska Mitrovica, Kosovska Mitrovica, Serbia. Dentogenous infections are among the most urgent conditions in dentistry, which may have even a fatal outcome. The aim of this study was to assess the possibility of using telemedicine methods in the pathology of dentogenous infections. Methods. This experimental randomized study incl uded 414 patients with suspected dentogenous infection. The patients were enrolled at 7 sites, with systematic photograph-taking, collection, and digitalization of the available anamnestic and laboratory data, tests, and x-rays. Together with clinical findings, the data were uploaded on the XPA3 Online central telemedicine system; after that, 10 teleconsultants reviewed the material, set the diagnosis, and gave their opinion about the treatment. The agreement was determined using the Cohen’s kappa (k coefficient, as well as diagnostic sensitivity (SE, specificity (SP, and efficacy (EFF. Statistical significance and comparisons were done using the z-test, and testing nonparametric properties using the McNemar’s χ2-test for the significance threshold of p = 0.05. Results. The results describing agreement of telemedicine diagnosis of the areas primarily involved with infection compared to clinical inspection, indicate an almost complete diagnostic agreement (k = 0.971. Diagnostic agreement as to the type of infection was also almost complete (k = 0.951, and a similar value was obtained also for the treatment agreement (k > =0.892. Conclusion. The method of telemedicine provides us with a tool to make a correct

    2017-10-16

    This article discusses recent applications in telemedicine to promote the goals of population health and population management for people suffering psychiatric disorders. The use of telemedicine to promote collaborative care, self-monitoring and chronic disease management, and population screening has demonstrated broad applicability and effectiveness. Collaborative care using videoconferencing to facilitate mental health specialty consults has demonstrated effectiveness in the treatment of depression, PTSD, and also ADHD in pediatric populations. Mobile health is currently being harnessed to monitor patient symptom trajectories with the goal of using machine learning algorithms to predict illness relapse. Patient portals serve as a bridge between patients and providers. They provide an electronically secure shared space for providers and patients to collaborate and optimize care. To date, research has supported the effectiveness of telemedicine in promoting population health. Future endeavors should focus on developing the most effective clinical protocols for using these technologies to ensure long-term use and maximum effectiveness in reducing population burden of mental health.

    Direct-to-consumer (DTC) telemedicine serves millions of patients; however, there is limited research on the care provided. This study compared the quality of care at Teladoc ( www.teladoc.com ), a large DTC telemedicine company, with that at physician offices and compared access to care for Teladoc users and nonusers. Claims from all enrollees 18-64 years of age in the California Public Employees' Retirement System health maintenance organization between April 2012 and October 2013 were analyzed. We compared the performance of Teladoc and physician offices on applicable Healthcare Effectiveness Data and Information Set measures. Using geographic information system analyses, we compared Teladoc users and nonusers with respect to rural location and available primary care physicians. Of enrollees offered Teladoc (n = 233,915), 3,043 adults had a total of 4,657 Teladoc visits. For the pharyngitis performance measure (ordering strep test), Teladoc performed worse than physician offices (3% versus 50%, p performance (88% versus 79%, p = 0.20). For the bronchitis measure (not ordering antibiotics), Teladoc performed worse than physician offices (16.7 versus 27.9%, p users were not more likely to be located within a healthcare professional shortage area (odds ratio = 1.12, p = 0.10) or rural location (odds ratio = 1.0, p = 0.10). Teladoc providers were less likely to order diagnostic testing and had poorer performance on appropriate antibiotic prescribing for bronchitis. Teladoc users were not preferentially located in underserved communities. Short-term needs include ongoing monitoring of quality and additional marketing and education to increase telemedicine use among underserved patients.

    In the management of edentulous spaces, there is a permanent need of a dentist-prosthetician in charge to consult other specialists. Modern telemedicine, based on powerful computer and telecomunication systems, offers an adequate answer to these challenges, being able to transfer and obtain clinical data and consultation information over large distances. Using smartphone or a computer, the teleconsultant acces the system, downloads and review the data and photographs and gave suggestions. The system then enables direct, real time contact with the consultant, chat, or directs them to contact each other by phone. We presented telemedicine consulting in the patient preparation and planning of prosthetic tooth replacement in 3 cases with different teleconsultation requirements: the first case for prosthetic rehabilitation of his upper teeth, the second one for prosthetic management of his partial edentulousness and "a growth on his gums" in the vestibular region of the frontal teeth and the third one for prosthetic management of total edentulousness of her upper jaw. We used the system of telemedicine in dentistry, established at the Faculty of Medicine in Kosovska Mitrovica. The operation was based on the computer application system XPA3 Online, computer networking and mobile smartphone network. All consultations were succefull with no need for further procedures in regional center. The use of a mobile smartphone has brought about the mobility and availability of teleconsultant specialists in an extent never seen before. Prostheticians are thus able to offer better service to their patients and improve the quality of management of partially or totally edentulous patients, especially in rural areas.

    Full Text Available In real-time remote diagnosis of emergency medical events, mobility can be enabled by wireless video communications. However, clinical use of this potential advance will depend on definitive and compelling demonstrations of the reliability of diagnostic quality video. Because the medical domain has its own fidelity criteria, it is important to incorporate diagnostic video quality criteria into any video compression system design. To this end, we used flexible algorithms for region-of-interest (ROI video compression and obtained feedback from medical experts to develop criteria for diagnostically lossless (DL quality. The design of the system occurred in three steps-measurement of bit rate at which DL quality is achieved through evaluation of videos by medical experts, incorporation of that information into a flexible video encoder through the notion of encoder states, and an encoder state update option based on a built-in quality criterion. Medical experts then evaluated our system for the diagnostic quality of the video, allowing us to verify that it is possible to realize DL quality in the ROI at practical communication data transfer rates, enabling mobile medical assessment over bit-rate limited wireless channels. This work lays the scientific foundation for additional validation through prototyped technology, field testing, and clinical trials.

    The expansion of information technology has shattered geographic boundaries, allowing for extraordinarily increased access to health information and expanded opportunities for telemedicine practice across state boundaries. But despite its recent growth, telemedicine technology remains embedded in a state-based licensure system that places severe limits on its expansion. The current system of medical licensure is based primarily on statutes written at the turn of the 20th century. This system is inadequate to address the emerging medical practices and future uses of medical technology in the telecommunications age. To respond to the changes offered by the telecommunications revolution, we need to design a new regulatory structure for the 21st century. The purpose of this article is to propose a policy of national telemedicine licensure. The primary goal here is not to simply develop a policy proposal, but to discuss the rationale for national licensure and place it on the policy agenda. A national licensure system will expand the market for telemedicine, promote both the use and development of new technologies, and simultaneously eliminate many of the legal and regulatory ambiguities that plague and constrain the present system.

    Telemedicine helps to deliver health services electronically to patients with the advancement of communication systems and health informatics. Chronic wound (CW) detection and its healing rate assessment at remote distance is very much difficult due to unavailability of expert doctors. This problem generally affects older ageing people. So there is a need of better assessment facility to the remote people in telemedicine framework. Here we have proposed a CW tissue prediction and diagnosis under telemedicine framework to classify the tissue types using linear discriminant analysis (LDA). The proposed telemedicine based wound tissue prediction (TWTP) model is able to identify wound tissue and correctly predict the wound status with a good degree of accuracy. The overall performance of the proposed wound tissue prediction methodology has been measured based on ground truth images. The proposed methodology will assist the clinicians to take better decision towards diagnosis of CW in terms of quantitative information of three types of tissue composition at low-resource set-up.

    This paper proposes a thorough framework for the economic evaluation of telemedicine networks. A standard cost analysis methodology was used as the initial base, similar to the evaluation method currently being applied to telemedicine, and to which we suggest adding subsequent stages that enhance the scope and sophistication of the analytical methodology. We completed the methodology with a longitudinal and stakeholder analysis, followed by the calculation of a break-even threshold, a calculation of the economic outcome based on net present value (NPV), an estimate of the social gain through external effects, and an assessment of the probability of social benefits. In order to illustrate the advantages, constraints and limitations of the proposed framework, we tested it in a paediatric cardiology tele-expertise network. The results demonstrate that the project threshold was not reached after the 4 years of the study. Also, the calculation of the project's NPV remained negative. However, the additional analytical steps of the proposed framework allowed us to highlight alternatives that can make this service economically viable. These included: use over an extended period of time, extending the network to other telemedicine specialties, or including it in the services offered by other community hospitals. In sum, the results presented here demonstrate the usefulness of an economic evaluation framework as a way of offering decision makers the tools they need to make comprehensive evaluations of telemedicine networks.

    Telemedicine with nonmydriatic cameras can detect not only diabetic retinopathy but also other eye disease. To determine the prevalence of eye diseases detected by telemedicine in a population with a high prevalence of minority and American Indian/Alaskan Native (AI/AN) ethnicities. We recruited diabetic patients 18 years and older and used telemedicine with nonmydriatic cameras to detect eye disease. Two trained readers graded the images for diabetic retinopathy, age-related macular degeneration (ARMD), glaucomatous features, macular edema, and other eye disease using a standard protocol. We included both eyes for analysis and excluded images that were too poor to grade. We included 820 eyes from 424 patients with 72.3% nonwhite ethnicity and 50.3% AI/AN heritage. While 283/424 (66.7%) patients had normal eye images, 120/424 (28.3%) had one disease identified; 15/424 (3.5%) had two diseases; and 6/424 (1.4%) had three diseases in one or both eyes. After diabetic retinopathy (104/424, 24.5%), the most common eye diseases were glaucomatous features (44/424, 10.4%) and dry ARMD (24/424, 5.7%). Seventeen percent (72/424, 17.0%) showed eye disease other than diabetic retinopathy. Telemedicine with nonmydriatic cameras detected diabetic retinopathy, as well as other visually significant eye disease. This suggests that a diabetic retinopathy screening program needs to detect and report other eye disease, including glaucoma and macular disease.

    Children in India constitute a very high risk group from mortality and morbidity due to lack of specialised healthcare. Remote care of paediatric patients by offsite specialists using telemedicine technology is a highly potential solution for coping up with the shortage of specialists in Indian subcontinent. We at a tertiary care teaching hospital in North India assessed the application of telemedicine services for diagnosis and management of paediatric illnesses, through prospective analyses of electronic databases over 4 years. The age groups covered were from newborn up to children of 15 years of age. The outcomes assessed were: feasibility, diagnostic possibilities, management, outcomes, referral and mean costs per patient. The results were as follows: major consultations involved children system-related problems were: gastrointestinal, respiratory, neurological, infectious and haematological. Referral was advised in 14.3% of cases. Ten percent of children were critically ill and could not have been in a position to be transported safely. Videoconferencing was done in 21.4% patients. There was a paucity of feedback and follow up of these consultations (12% of the total). The total savings for all the consultations per child was ≈1000 Indian rupees (approximately US$22) leaving behind the telemedicine consultation charges. To conclude, telepaediatrics in India is still in its fetal stage. The hurdles and medico-legal issues need to be addressed before the telepaediatrics service is widely accepted in India.

    Introduction and objective Studies on telemedicine have shown success in reducing the geographical and time obstacles incurred in the receipt of care in traditional modalities with the same or greater effectiveness; however, there are several barriers that need to be addressed in order for telemedicine technology to spread. The aim of this review is to evaluate barriers to adopting telemedicine worldwide through the analysis of published work. Methods The authors conducted a systematic literature review by extracting the data from the Cumulative Index of Nursing and Allied Health Literature (CINAHL) and PubMed (MEDLINE) research databases. The reviewers in this study analysed 30 articles (nine from CINAHL and 21 from Medline) and identified barriers found in the literature. This review followed the checklist from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009. The reviewers organized the results into one table and five figures that depict the data in different ways, organized by: barrier, country-specific barriers, organization-specific barriers, patient-specific barriers, and medical-staff and programmer-specific barriers. Results The reviewers identified 33 barriers with a frequency of 100 occurrences through the 30 articles. The study identified the issues with technically challenged staff (11%), followed by resistance to change (8%), cost (8%), reimbursement (5%), age of patient (5%), and level of education of patient (5%). All other barriers occurred at or less than 4% of the time. Discussion and conclusions Telemedicine is not yet ubiquitous, and barriers vary widely. The top barriers are technology-specific and could be overcome through training, change-management techniques, and alternating delivery by telemedicine and personal patient-to-provider interaction. The results of this study identify several barriers that could be eliminated by focused policy. Future work should evaluate policy to identify which one to lever to

    INTRODUCTION: Long-duration missions beyond low Earth orbit introduce new constraints to the space medical system such as the inability to evacuate to Earth, communication delays, and limitations in clinical skillsets. NASA recognizes the need to improve capabilities for autonomous care on such missions. As the medical system is developed, it is important to have an ability to evaluate the trade space of what resources will be most important. The Medical Optimization Network for Space Telemedicine Resources was developed for this reason, and is now a system to gauge the relative importance of medical resources in addressing medical conditions. METHODS: A list of medical conditions of potential concern for an exploration mission was referenced from the Integrated Medical Model, a probabilistic model designed to quantify in-flight medical risk. The diagnostic and treatment modalities required to address best and worst-case scenarios of each medical condition, at the terrestrial standard of care, were entered into a database. This list included tangible assets (e.g. medications) and intangible assets (e.g. clinical skills to perform a procedure). A team of physicians working within the Exploration Medical Capability Element of NASA's Human Research Program ranked each of the items listed according to its criticality. Data was then obtained from the IMM for the probability of occurrence of the medical conditions, including a breakdown of best case and worst case, during a Mars reference mission. The probability of occurrence information and criticality for each resource were taken into account during analytics performed using Tableau software. RESULTS: A database and weighting system to evaluate all the diagnostic and treatment modalities was created by combining the probability of condition occurrence data with the criticalities assigned by the physician team. DISCUSSION: Exploration Medical Capabilities research at NASA is focused on providing a medical system to

    Managers and policy makers face new and as yet unrecognised challenges--particularly loss of control--through the application of new information technologies in healthcare. Whilst informatics and telemedicine are important developments, the potential for adverse organisational and societal effects should be recognised and anticipated. Health organisations are frequently seen as circumscribed networks, and these in turn form local alliances with related organisations. Information technologies are frequently construed as relating to operational systems within organisations, not least electronic patient record systems and diagnostic systems. These can then be linked to new generation health business systems, to provide accurate management information at low additional cost. However, this pair of assumptions is now seriously flawed, due to the effects of the latest developments in health informatics and telemedicine. In particular, telecommunications and Internet technologies render ineffectual previous external barriers of distance and national boundaries, whilst within the organisation the combination of knowledge bases with information technologies creates tendencies towards internal autonomy. Organisational and national policy control of health care face direct and radical challenges through perverse effects of otherwise beneficial developments, and early action is needed.

    Background Telemedicine services have been successfully used in areas where there are adequate infrastructures such as reliable power and communication lines. However, despite the increasing number of merchants and seafarers, maritime and Arctic telemedicine have had limited success. This might be linked with various factors such as lack of good infrastructure, lack of trained onboard personnel, lack of Arctic-enhanced telemedicine equipment, extreme weather conditions, remoteness, and other geographical challenges. Objective The purpose of this review was to assess and analyze the current status of telemedicine services in the context of maritime conditions, extreme weather (ie, Arctic weather), and remote accidents and emergencies. Moreover, the paper aimed to identify successfully implemented telemedicine services in the Arctic region and in maritime settings and remote emergency situations and present state of the art systems for these areas. Finally, we identified the status quo of telemedicine services in the context of search and rescue (SAR) scenarios in these extreme conditions. Methods A rigorous literature search was conducted between September 7 and October 28, 2015, through various online databases. Peer reviewed journals and articles were considered. Relevant articles were first identified by reviewing the title, keywords, and abstract for a preliminary filter with our selection criteria, and then we reviewed full-text articles that seemed relevant. Information from the selected literature was extracted based on some predefined categories, which were defined based on previous research and further elaborated upon via iterative brainstorming. Results The initial hits were vetted using the title, abstract, and keywords, and we retrieved a total of 471 papers. After removing duplicates from the list, 422 records remained. Then, we did an independent assessment of the articles and screening based on the inclusion and exclusion criteria, which eliminated

    Benefits associated with telemedicine are contingent upon positive user perceptions. Despite this, research on user perceptions of telemedicine remains limited. Usability approaches offer a robust way to assess user perceptions, but have rarely been applied in telemedicine. In this study, a usability approach was employed to examine how user perceptions toward a telemedicine system changed over the course of everyday use. A telemedicine system was introduced to a hospital in the home service. Ten mobile nurses completed the System Usability Scale (SUS) after initial use, then again after 18 months of everyday use. Results were compared. Analysis included Bangor et al.'s (2009) adjective rating scale. The initial SUS mean was 83 (standard deviation [SD] = 7.98), indicating "excellent" usability. After 18 months, the SUS mean was 64.38, indicating "OK" usability (SD = 14.25, p benefits and longevity of telemedicine systems, responding to intermittent user appraisal is desirable.

    2006-10-01

    Telemedicine, the use of telecommunication technologies to provide health services over some distance, has a history that spans more than five decades. Technological development and deployment have been interrelated with shifting paradigmatic views. This paper proposes that telemedicine has evolved through three generations that began with telemedicine as a communication medium to complement traditional services to a technology of automation and decision tools that expands the scope and range of health services and creates a unique health communication context. This paper provides a literature review and overviews three proposed evolutionary stages for telemedicine to date, namely synchronous versus asynchronous modalities, data transfer and storage, and automating decision making and robotics. Finally, we conclude with a discussion of the barriers for telemedicine and a call for engineers to join with social scientists and medical professionals to set an agenda for future telemedicine development.

    Objective To determine whether a diabetes case management telemedicine intervention reduced healthcare expenditures, as measured by Medicare claims, and to assess the costs of developing and implementing the telemedicine intervention. Design We studied 1665 participants in the Informatics for Diabetes Education and Telemedicine (IDEATel), a randomized controlled trial comparing telemedicine case management of diabetes to usual care. Participants were aged 55 years or older, and resided in federally designated medically underserved areas of New York State. Measurements We analyzed Medicare claims payments for each participant for up to 60 study months from date of randomization, until their death, or until December 31, 2006 (whichever happened first). We also analyzed study expenditures for the telemedicine intervention over six budget years (February 28, 2000– February 27, 2006). Results Mean annual Medicare payments (SE) were similar in the usual care and telemedicine groups, $9040 ($386) and $9669 ($443) per participant, respectively (p>0.05). Sensitivity analyses, including stratification by censored status, adjustment by enrollment site, and semi-parametric weighting by probability of dropping-out, rendered similar results. Over six budget years 28 821 participant/months of telemedicine intervention were delivered, at an estimated cost of $622 per participant/month. Conclusion Telemedicine case management was not associated with a reduction in Medicare claims in this medically underserved population. The cost of implementing the telemedicine intervention was high, largely representing special purpose hardware and software costs required at the time. Lower implementation costs will need to be achieved using lower cost technology in order for telemedicine case management to be more widely used. PMID:20190064

    Many developing countries have shown interest in embracing telemedicine and incorporating it into their healthcare systems. In 2000, the U.S. Army Yuma Proving Ground (YPG) initiated a program to assist the Republic of Panama in establishing a demonstration Panamanian rural telemedicine program. YPG engaged the Arizona Telemedicine Program (ATP) to participate in the development and implementation of the program. The ATP recommended adoption of a "top-down" strategy for creating the program. Early buy-in of the Panamanian Ministry of Health and academic leaders was regarded as critical to the achievement of long-term success. High-level meetings with the Minister of Health and the Rectors (i.e., Presidents) of the national universities gained early program support. A telemedicine demonstration project was established on a mountainous Indian reservation 230 miles west of Panama City. Today, three rural telemedicine clinics are linked to a regional Ministry of Health hospital for teleconsultations. Real-time bidirectional videoconferencing utilizes videophones connected over Internet protocol networks at a data rate of 768 kilobits per second to the San Felix Hospital. Telepediatrics, tele-obstetrics, telepulmonology, teledermatology, and tele-emergency medicine services became available. Telemedicine services were provided to the three sites for a total of 1,013 cases, with numbers of cases increasing each year. These three demonstration sites remained in operation after discontinuation of the U.S. involvement in September 2009 and serve as a model program for other telemedicine initiatives in Panama. Access to the assets of a partner-nation was invaluable in the establishment of the first model telemedicine demonstration program in Panama. After 3 years, the Panamanian Telemedicine and Telehealth Program (PTTP) became self-sufficient. The successful achievement of sustainability of the PTTP after disengagement by the United States fits the Latifi-Weinstein model

    Visual images can enhance communication over a distance. In the UK, plastic surgery provides services over large distances by a 'hub and spoke' model. Telemedicine could help to increase the efficiency of service for plastic surgery patients. Telemedicine, along with the impending Electronic Patient Record system could combine to improve communication, patient triage, record keeping, audit and could lead to a better quality of clinical care. Another benefit could be significant cost savings. We report our experience of the introduction of telemedicine to a Regional Plastic Surgery Service. Our first study compared assessments from images and patient examinations, which gave us confidence in the use of images [Jones SM, Milroy C, Pickford MA. Telemedicine in acute plastic surgical trauma and burns. Ann R Coll Surg Engl 2004;86:239-42]. We proceeded to a 10-week evaluation of all 973 referrals to our unit. We found that the system was used for a wide variety of injuries and for 42% of the 452 patients where the system was available. Initial resistance was overcome by the ease of use of the system, with both receiving and referring clinicians reporting benefits. The third phase was a 12-week prospective cohort study of 996 patients comparing the referrals with and without the telemedicine system. The system was available for 389 patients, and used for 243 patients (63%). The groups were analysed by a chi squared test and confidence interval calculation. We demonstrated a significant difference in the initial management of patients, with 10% more being booked directly to our Day Surgery Unit. There was a decrease in number of occasions when we were unable to accept a patient due to a lack of capacity. We found no change in the patients being managed with telephone only advice. We found that telemedicine is a valuable method of providing useful preliminary information in the referral process for injured patients and often significantly modifies their treatment and

    Geospatial Information Systems (GIS) superimpose data on geographical maps to provide visual representations of data by region. Few studies have used GIS data to investigate if telemedicine services are preferentially provided to communities of greatest need. This study compared the healthcare needs of communities with and without telemedicine services from a university-based telemedicine program. Originating sites for all telemedicine consultations between July 1996 and December 2013 were geocoded using ArcGIS software. ZIP Code Tabulation Areas (ZCTAs) were extracted from the 2010 U.S. Census Bureau's Topologically Integrated Geographic Encoding and Referencing file and assigned a community needs index (CNI) score to reflect the ZCTA community's healthcare needs based on evidence-based barriers to healthcare access. CNI scores were compared across communities with and without active telemedicine services. One hundred ninety-four originating telemedicine clinic sites in California were evaluated. The mean CNI score for ZCTAs with at least one telemedicine clinic was significantly higher (3.32 ± 0.84) than those without a telemedicine site (2.95 ± 0.99) and higher than the mean ZCTAs for all of California (2.99 ± 1.01). Of the 194 telemedicine clinics, 71.4% were located in communities with above average need and 33.2% were located in communities with very high needs. Originating sites receiving telemedicine services from a university-based telemedicine program were located in regions with significantly higher community healthcare needs. Leveraging a geospatial information system to understand community healthcare needs provides an opportunity for payers, hospitals, and patients to be strategic in the allocation of telemedicine services.

    ICU telemedicine uses audiovisual conferencing technology to provide critical care from a remote location. Research is needed to best define the optimal use of ICU telemedicine, but efforts are hindered by methodological challenges and the lack of an organized delivery approach. We convened an interdisciplinary working group to develop a research agenda in ICU telemedicine, addressing both methodological and knowledge gaps in the field. To best inform clinical decision-making and health policy, future research should be organized around a conceptual framework that enables consistent descriptions of both the study setting and the telemedicine intervention. The framework should include standardized methods for assessing the preimplementation ICU environment and describing the telemedicine program. This framework will facilitate comparisons across studies and improve generalizability by permitting context-specific interpretation. Research based on this framework should consider the multidisciplinary nature of ICU care and describe the specific program goals. Key topic areas to be addressed include the effect of ICU telemedicine on the structure, process, and outcome of critical care delivery. Ideally, future research should attempt to address causation instead of simply associations and elucidate the mechanism of action in order to determine exactly how ICU telemedicine achieves its effects. ICU telemedicine has significant potential to improve critical care delivery, but high-quality research is needed to best inform its use. We propose an agenda to advance the science of ICU telemedicine and generate research with the greatest potential to improve patient care.

    Kahn, Elyne N; La Marca, Frank; Mazzola, Catherine A

    2016-05-01

    Telemedicine has seen substantial growth in the past 20 years, related to technologic advancements and evolving reimbursement policies. The risks and opportunities of neurosurgical telemedicine are nuanced. We reviewed general and peer-reviewed literature as it relates to telemedicine and neurosurgery, with particular attention to best practices, relevant state and federal policy conditions, economic evaluations, and prospective clinical studies. Despite technologic development, growing interest, and increasing reimbursement opportunities, telemedicine's utilization remains limited because of concerns regarding an apparent lack of need for telemedicine services, lack of widespread reimbursement, lack of interstate licensure reciprocity, lack of universal access to necessary technology, concerns about maintaining patient confidentiality, and concerns and limited precedent regarding liability issues. The Veterans Health Administration, a component of the U.S. Department of Veterans Affairs, represents a setting in which these concerns can be largely obviated and is a model for telemedicine best practices. Results from the VA demonstrate substantial cost savings and patient satisfaction with remote care for chronic neurologic conditions. Overall, the economic and clinical benefits of telemedicine will likely come from 1) diminished travel times and lost work time for patients; 2) remote consultation of subspecialty experts, such as neurosurgeons; and 3) remote consultation to assist with triage and care in time-sensitive scenarios, including acute stroke care and "teletrauma." Telemedicine is effective in many health care scenarios and will become more relevant to neurosurgical patient care. We favor proceeding with legislation to reduce barriers to telemedicine's growth.

    Full Text Available During our literature review and on-site research in developing countries, particularly in Sub-Saharan Africa, we could not point out any efforts to measure the Quality of Service (QoS and Quality of Experience (QoE provided by telemedicine systems, thus making it impossible to understand their overall levels of user satisfaction in sub-Saharan African countries. Therefore, we conducted a qualitative and quantitative study, with experiments to measure QoS performance and the end-user QoE perception of telemedicine systems. Based on obtained results, we propose a mathematical formula to predict the QoE based on QoS measurement values, since a known relationship exists between QoS and QoE.

    Full Text Available Yousef lives in a remote area of Pakistan with limited access to healthcare. As a result of not having proper disagnoses, care or medication, Yousef’s hypertension has begun to damage his heart. A major barrier for Yousef getting good healthcare is the long distance between the village and quality care hospitals that are miles away, so he becomes a patient at the local village quack clinic that is not qualified to treat Yousef’s complicated health condition. Telemedicine in the form of Health Relationship Management Services (HRMS has come to the village, so now, Yousef can receive proper diagnoses, advice, medication and treatment without having to travel afar. Telemedicine allows specialists that are miles away to access Yousef’s personal health data to make meaningful decisions about his healthcare.

  11. Fluctuations in telemedicine case volume: correlation with personnel turnover rates.

    Krupinski, Elizabeth A; Hughes, Alison M; Barker, Gail P; Lopez, Ana Maria; Weinstein, Ronald S

    2003-01-01

    Statistical process control (SPC) techniques were used to analyze 5 years worth of telemedicine case volume data from seven remote sites in order to characterize how much fluctuation occurred over time for each site and whether the fluctuation remained within prescribed limits. The points at which the fluctuations were considered beyond the prescribed limits were correlated with the turnover rate in key personnel (e.g., the Medical Director). Though no causal relationship can be implied, sites with higher turnover rates tended to fluctuate more. The analyses suggest that SPC may be a useful tool for analyzing trends in telemedicine consultation volume fluctuations over time and, therefore, may be useful for program management and allocation of personnel resources. It can also be used in the long run to determine when and why fluctuations occur and whether the causes of fluctuations need to be addressed.

    The combination of information and communication technologies (ICTs) for sustainable healthcare through telemedicine focuses on both changes in the access of healthcare information services as well as wider dissemination of healthcare related skills and professional expertise of medical community. Many developing countries are deficient in healthcare services and suffer from a shortage of doctors and other healthcare Professionals. In Pakistan, the inadequate allocation of doctors/specialists, infrastructures of telecommunications, roads and transport make it more difficult to provide in remote and rural areas. Where clinics and hospitals exist, they are often ill-equipped. The aim of this paper is to share knowledge about the use of telemedic solutions in the health sector in order to propose strategies and actions to formulate tactical recommendations for policy makers and advisors as well as researchers. The examples in this paper illustrate that telemedicine has clearly made an impact on healthcare. (author)

    In this paper, the authors discuss compression based on some new ideas in vector quantization and their incorporation in a sub-band coding framework. Several variations are considered, which collectively address many of the individual compression needs within the earth science community. The approach taken in this work is based on some recent advances in the area of variable rate residual vector quantization (RVQ). This new RVQ method is considered separately and in conjunction with sub-band image decomposition. Very good results are achieved in coding a variety of earth science images. The last section of the paper provides some comparisons that illustrate the improvement in performance attributable to this approach relative the the JPEG coding standard.

    The first step in each systematic review is selection of the most valid database that can provide the highest number of relevant references. This study was carried out to determine the most suitable database for information retrieval in telemedicine field. Cinhal, PubMed, Web of Science and Scopus databases were searched for telemedicine matched with Education, cost benefit and patient satisfaction. After analysis of the obtained results, the accuracy coefficient, sensitivity, uniqueness and overlap of databases were calculated. The studied databases differed in the number of retrieved articles. PubMed was identified as the most suitable database for retrieving information on the selected topics with the accuracy and sensitivity ratios of 50.7% and 61.4% respectively. The uniqueness percent of retrieved articles ranged from 38% for Pubmed to 3.0% for Cinhal. The highest overlap rate (18.6%) was found between PubMed and Web of Science. Less than 1% of articles have been indexed in all searched databases. PubMed is suggested as the most suitable database for starting search in telemedicine and after PubMed, Scopus and Web of Science can retrieve about 90% of the relevant articles.

  1. Use of telemedicine to improve burn care in Ukraine.

    Science.gov (United States)

    Fuzaylov, Gennadiy; Knittel, Justin; Driscoll, Daniel N

    2013-01-01

    Global burn injuries have been described as the "forgotten public health crises" by the World Health Organization. Nearly 11 million people a year suffer burns severe enough to require medical attention; more people are burned each year than are infected with human immunodeficiency virus/acquired immunodeficiency syndrome and tuberculosis combined. Telemedicine has the potential to link experts in specialized fields, such as burn care, to regions of the world that have limited or no access to such specialized care. A multilevel telemedicine program was developed between Massachusetts General Hospital/Shriners Hospital in Boston, Massachusetts, and City Hospital #8 in Lviv, Ukraine. The program should lead to a sustainable improvement in the care of burn victims in Ukraine. The authors helped establish a Learning Center at City Hospital #8 in Lviv, Ukraine, through which they were able to consult from Shriners Hospital in Boston, on a total of 14 acute burn patients in Ukraine. This article discusses two case reports with the use of telemedicine and how it has allowed the authors to provide not only acute care consultation on an international scale, but also to arrange for direct expert examination and international transport to their specialized burn center in the United States. The authors have established a program through doctors from Massachusetts General Hospital/Shriner's Hospital in Boston, which works with a hospital in Ukraine and has provided acute consultation, as well as patient transportation to the United States for treatment and direct assessment.

    Glaucoma is one of the most common causes of blindness in the Western world and a major risk factor is increased intra-ocular pressure. We therefore used telemedicine in its control. Patients measured their intra-ocular pressure several times a day with a portable instrument and the values were then entered into a portable digital assistant. These data were transmitted by a modem to a central server. If the intra-ocular pressure was pathologically high, an email message was automatically sent to the ophthalmologist. The pressure curve, including a statistical analysis, was displayed in an easily readable chart format. Ten patients with glaucoma participated in a trial. Self-tonometry with telemedicine enabled continuous evaluation of the patient by the ophthalmologist. This approach offered the advantage of controlling the treatment remotely. Advantages for the patient were that the measurements were easily done at home under normal conditions, and the patient could control when the measurement and data transmission would be performed. Telemedicine is a cost-effective technique enabling the early diagnosis of pathologically increased intra-ocular pressure.

    Full Text Available Objective. The objective was to define and evaluate a role for the Vascular Neurology-Nurse Practitioner (VN-NP in the delivery of telemedicine consultations in partnership with a vascular neurologist. Methods. Prospective stroke alert patients at participating hospitals underwent a two-way audio video telemedicine consultation with a VN-NP at a remotely located stroke center in partnership with a vascular neurologist. Demographic information, National Institutes of Health Stroke Scale (NIHSS scores, diagnoses, CT contraindications to thrombolysis, thrombolysis eligibility, and time interval data were collected. The inter-rater agreement between VN-NP and vascular neurologist assessments was calculated. Results. Ten patients were evaluated. Four were determined to have ischemic stroke, one had a transient ischemic attack, two had intracerebral hemorrhages, and three were stroke mimics. Overall, three patients received thrombolysis. The inter-rater agreement between VN-NP and vascular neurologist assessments were excellent, ranging from 0.9 to 1.0. The duration of VN-NP consultation was 53.2±9.0 minutes, which included the vascular neurologist supervisory evaluation time of 12.0±9.6 minutes. Conclusion. This study illustrated that a stroke center VN-NP, in partnership with a vascular neurologist, could deliver timely telemedicine consultations, accurate diagnoses, and correct treatments in acute stroke patients who presented to remotely located rural emergency departments within a hub and spoke network. VN-NPs may fulfill the role of a telestroke provider.

    The increasing digitization of our lives and work has also reached medicine and is changing the profession of medical doctors. The modern forms of communication and cooperation in everyday medical practice demand new skills and qualifications. To enable future doctors to comply with this digitally competent profile, an innovative blended learning curriculum was developed and first implemented at the University Medical Center Mainz in summer semester 2017-Medicine in the Digital Age. The teaching concept encompasses five modules, each consisting of an e‑learning unit and a 3-hour classroom course. This publication presents the teaching concept, the initial implementation and evaluation of the module "Telemedicine". The competency development in the field of telemedicine showed a significant increase for the subcomponents "knowledge" and "skills". The neutral attitude towards telemedicine at the beginning of the module could be changed to a positive opinion after the session. The teaching of digital skills is a relevant component of future curriculum development in medical studies and also a challenge for continuing medical education.

    We evaluated the effect of a telemedicine system on maternal and fetal outcome in women with diabetes. A total of 276 pregnant women were enrolled in the study. Women were sequentially assigned to a telemedicine or a control group. There were 88 women with gestational diabetes in the telemedicine group and 115 in the control group; there were 17 women with type 1 diabetes in the telemedicine group and 15 in the control group. Women in telemedicine groups were asked to submit their blood glucose data every week, and had a medical examination at the diabetes clinic once a month. Women in the control groups had a medical examination every two weeks. Subjective outcomes were investigated using the following questionnaires: CES-D for depression, SF-36 for health-related quality of life (QoL), Stress and Distress for the impact of diabetes. Clinical variables and pregnancy outcomes were no different between the two telemedicine groups, whereas women with gestational diabetes in the telemedicine group had a better metabolic control in the 3rd trimester and a lower rate of caesarean sections and macrosomia. As for QoL, women in the telemedicine groups showed lower levels of frustration and concerns about their diabetes, and a better acceptance of their diabetic condition. A questionnaire on the use of the telemedicine system showed a high degree of acceptance (85%). Both telemedicine groups had fewer check-ups at the diabetes clinics. The use of a telemedicine system for glucose monitoring improved pregnancy outcome in women with gestational diabetes and improved QoL in all diabetic pregnancies.

    To evaluate the utility in telemedicine of Three-Dimensional Radiotherapy Treatment Planning (tele-3D-RTP) and to examine the accuracy of isocenter reproducibility in its offline trial. CT data of phantoms and patients in the satellite hospital were transferred to our hospital via floppy-disk and 3D-radiotherapy plans were generated by 3D-RTP computer in our hospital. Profile data of CT and treatment beams in the satellite hospital were pre-installed into the computer. Tele-3D-RTPs were performed in 3 phantom plans and 14 clinical plans for 13 patients. Planned isocenters were well reproduced, especially in the immobilized head and neck/brain tumor cases, whose 3D-vector of aberration was 1.96±1.38 (SD) mm. This teletherapy system is well applicable for practical use and can provides cost-reduction through sharing the resources of expensive equipment and radiation oncologists. (author)

    2007-01-01

    The objective of this study was to compare doctor-patient communications in clinical consultations via telemedicine technology to doctor-patient communications in face-to-face clinical consultations. Five doctors who had been practicing internal medicine for 8 to 18 years, and twenty patients were enrolled in this study; neither doctors nor patients had previous experience of telemedicine. The patients received both a telemedicine consultation and a face-to-face consultation. Three measures--video observation, medical record volume, and participants' satisfaction--were used for the assessment. It was found that the time spent on the telemedicine consultation was substantially longer than the time spent on the face-to-face consultation. No statistically significant differences were found in the number of either closed or open-ended questions asked by doctors between both types of consultation. Empathy-utterances, praise-utterances, and facilitation-utterances were, however, seen less in the telemedicine consultations than in the face-to-face consultations. The volume of the medical records was statistically smaller in the telemedicine consultations than in the face-to-face consultations. Patients were satisfied with the telemedicine consultation, but doctors were dissatisfied with it and felt hampered by the communication barriers. This study suggests that new training programs are needed for doctors to develop improved communication skills and the ability to express empathy in telemedicine consultations.

    The healthcare sector is a significant contributor to global carbon emissions, in part due to extensive travelling by patients and health workers. To evaluate the potential of telemedicine services based on videoconferencing technology to reduce travelling and thus carbon emissions in the healthcare sector. A life cycle inventory was performed to evaluate the carbon reduction potential of telemedicine activities beyond a reduction in travel related emissions. The study included two rehabilitation units at Umeå University Hospital in Sweden. Carbon emissions generated during telemedicine appointments were compared with care-as-usual scenarios. Upper and lower bound emissions scenarios were created based on different teleconferencing solutions and thresholds for when telemedicine becomes favorable were estimated. Sensitivity analyses were performed to pinpoint the most important contributors to emissions for different set-ups and use cases. Replacing physical visits with telemedicine appointments resulted in a significant 40-70 times decrease in carbon emissions. Factors such as meeting duration, bandwidth and use rates influence emissions to various extents. According to the lower bound scenario, telemedicine becomes a greener choice at a distance of a few kilometers when the alternative is transport by car. Telemedicine is a potent carbon reduction strategy in the health sector. But to contribute significantly to climate change mitigation, a paradigm shift might be required where telemedicine is regarded as an essential component of ordinary health care activities and not only considered to be a service to the few who lack access to care due to geography, isolation or other constraints.

    The integration of telecommunications and information systems in health care first began 4 decades ago with 500 patient consultations performed via interactive television. The use of telemedicine services and technology to deliver health care at a distance is increasing exponentially. Concomitant with this rapid expansion is the exciting ability to provide enhancements in quality and safety of care. Telemedicine enables increased access to care, improvement in health outcomes, reduction in medical costs, better resource use, expanded educational opportunities, and enhanced collaboration between patients and physicians. These potential benefits should be weighed against the risks and challenges of using telemedicine. The American College of Allergy, Asthma, and Immunology advocates for incorporation of meaningful and sustained use of telemedicine in allergy and immunology practice. This article serves to offer policy and position statements of the use of telemedicine pertinent to the allergy and immunology subspecialty.

    The telemedicine system aims at monitoring patients remotely without limit in time and space. However the existing telemedicine systems exchange medical information simply in a specified location. Due to increasing speed in processing data and expanding bandwidth of wireless networks, it is possible to perform telemedicine services on personal digital assistants (PDA). In this paper, a telemedicine system on PDA was developed using wideband mobile networks such as Wi-Fi, HSDPA, and WiBro for high speed bandwidths. This system enables to utilize and exchange variety and reliable patient information of video, biosignals, chatting messages, and triage data. By measuring bandwidths of individual data of the system over wireless networks, and evaluating the performance of this system using PDA, we demonstrated the feasibility of the designed portable emergency telemedicine system.

    The basic research question that guided this investigation was "Do financial indicators play a major role in decisions to deploy telemedicine?" The study also evaluated the relative importance of five specific financial indicators. Select hospital systems were asked to participate in this research. Because much has been written about the problems of access to health care in rural settings, the study included hospital systems with rural hospitals. The study also examined the importance of financial indicators to representatives of various functional disciplines. A qualitative case study approach was used for the research project.

  1. Medication Abortion Through Telemedicine: Implications of a Ruling by the Iowa Supreme Court.

    Science.gov (United States)

    Yang, Y Tony; Kozhimannil, Katy B

    2016-02-01

    In summer 2015, the Iowa Supreme Court unanimously struck down a restriction that would have prevented physicians from administering a medication abortion remotely through video teleconferencing. In its ruling, the Iowa Supreme Court stated that the restriction would have placed an undue burden on a woman's right to access abortion services. It is crucially important for clinicians--especially primary care clinicians, obstetrician-gynecologists (ob-gyns), and all health care providers of telemedicine services--to understand the implications of this recent ruling, especially in rural settings. The Court's decision has potential ramifications across the country, for both women's access to abortion and the field of telemedicine. Today telemedicine abortion is available only in Iowa and Minnesota; 18 states have adopted bans on it. If telemedicine abortions are indeed being unconstitutionally restricted as the Iowa Supreme Court determined, court decisions reversing these bans could improve access to abortion services for the 21 million reproductive-age women living in these 18 states, which have a limited supply of ob-gyns, mostly concentrated in urban, metropolitan areas. Beyond the potential effects on abortion access, we argue that the Court's decision also has broader implications for telemedicine, by limiting the role of state boards of medicine regarding the restriction of politically controversial medical services when provided through telemedicine. The interplay between telemedicine policy, abortion politics, and the science of medicine is at the heart of the Court's decision and has meaning beyond Iowa's borders for reproductive-age women across the United States.

    Cost analysis and patient satisfaction with telemedicine in epilepsy care. This controlled study included out-of-town epilepsy patients coming to follow-up at the University of Alberta hospital epilepsy clinic. After an informed consent, patients were randomized to either conventional (n = 18) or telemedicine (n = 23) clinics. Patients or caregivers filled patient satisfaction and travel cost questionnaires in both alternatives. Cost per visit analysis included costs of traveling, lodging, and lost productivity. Average age of the population was 41 years (range 19-73; 45% women). Eighty-three percent of patients preferred their next visit through telemedicine. About 90% of patients indicated a need for companion travel (mainly by car) to conventional clinic. For the conventional group patients the value of lost productivity was CAD $201, hotel cost CAD $8.50, and the value of car mileage CAD $256.50, totaling about CAD $466.00. Patient costs for telemedicine were CAD $35.85. Telemedicine production costs are similar to the patients' savings in traveling and lost productivity. About 90% of patients in both groups were satisfied with the quality of the service. Telemedicine can play a role in follow-up care of epilepsy patients, reduce patient costs, and improve patient satisfaction. This is the first full-time epilepsy telemedicine clinic in Western Canada.

  3. Pharmacists providing care in the outpatient setting through telemedicine models: a narrative review

    2017-12-01

    Full Text Available Telemedicine refers to the delivery of clinical services using technology that allows two-way, real time, interactive communication between the patient and the clinician at a distant site. Commonly, telemedicine is used to improve access to general and specialty care for patients in rural areas. This review aims to provide an overview of existing telemedicine models involving the delivery of care by pharmacists via telemedicine (including telemonitoring and video, but excluding follow-up telephone calls and to highlight the main areas of chronic-disease management where these models have been applied. Studies within the areas of hypertension, diabetes, asthma, anticoagulation and depression were identified, but only two randomized controlled trials with adequate sample size demonstrating the positive impact of telemonitoring combined with pharmacist care in hypertension were identified. The evidence for the impact of pharmacist-based telemedicine models is sparse and weak, with the studies conducted presenting serious threats to internal and external validity. Therefore, no definitive conclusions about the impact of pharmacist-led telemedicine models can be made at this time. In the Unites States, the increasing shortage of primary care providers and specialists represents an opportunity for pharmacists to assume a more prominent role managing patients with chronic disease in the ambulatory care setting. However, lack of reimbursement may pose a barrier to the provision of care by pharmacists using telemedicine.

    This study evaluates the financial impact of telemedicine outreach in a competitive healthcare market from a tertiary children's hospital's perspective. We compared the number of transfers, average hospital revenue, and average professional billing revenue before and after the deployment of telemedicine. This is a retrospective review of hospital and physician billing records for patients transferred from 16 hospitals where telemedicine services were implemented between July 2003 and December 2010. Hospital revenue was defined as total revenue minus operating costs. Professional billing revenue was defined as total payment received as the result of physician billing of patients' insurance. We compared the number of transfers, average net hospital revenue per year, and average professional billing revenue per year before and after the deployment of telemedicine at these hospitals. There were 2,029 children transferred to the children's hospital from the 16 hospitals with telemedicine during the study period. The average number of patients transferred per year to the children's hospital increased from 143 pre-telemedicine to 285 post-telemedicine. From these patients, the average hospital revenue increased from $2.4 million to $4.0 million per year, and the average professional billing revenue increased from $313,977 to $688,443 per year. On average, per hospital, following the deployment of telemedicine, hospital revenue increased by $101,744 per year, and professional billing revenue increased by $23,404 per year. In a competitive healthcare region with more than one children's hospital, deploying pediatric telemedicine services to referring hospitals resulted in an increased market share and an increased number of transfers, hospital revenue, and professional billing revenue.

    Full Text Available Introduction. Diabetic retinopathy (DR is a sight-threatening complication of diabetes. Telemedicine tools can prevent blindness. We aimed to investigate the patients’ satisfaction when using such tools (fundus camera examination and the effect of demographic and socioeconomic factors on participation in screening. Methods. Pilot study involving fundus camera screening and self-administered questionnaire on participants’ experience during fundus examination (comfort, reliability, and future interest in participation, as well as demographic and socioeconomic factors was performed on 89 patients with known diabetes in Csongrád County, a southeastern region of Hungary. Results. Thirty percent of the patients had never participated in any ophthalmological screening, while 25.7% had DR of some grade based upon a standard fundus camera examination and UK-based DR grading protocol (Spectra™ software. Large majority of the patients were satisfied with the screening and found it reliable and acceptable to undertake examination under pupil dilation; 67.3% were willing to undergo nonmydriatic fundus camera examination again. There was a statistically significant relationship between economic activity, education and marital status, and future interest in participation. Discussion. Participants found digital retinal screening to be reliable and satisfactory. Telemedicine can be a strong tool, supporting eye care professionals and allowing for faster and more comfortable DR screening.

    The Swinfen Charitable Trust uses digital cameras and email to provide specialist advice to doctors in developing countries. The first telemedicine link was set up in July 1999. By the end of a year there were three links to hospitals in Bangladesh, Nepal and the Solomon Islands. Initially the consultants, all of whom give their advice free of charge, were from the UK, but now are worldwide. At present there are 12 links in operation, including one on Tristan da Cunha, and two links approved and awaiting equipment. The advice given by the consultants has been found to be helpful to the referring doctors and to benefit their patients. Failures have been due to the use of obsolescent equipment, computer viruses, lack of communication with the referring hospital before setting up a link, and referring doctors not chasing up their own referrals. Problems yet to be solved include the unreliability of the Internet, certain medicolegal issues and assessing the quality of medical consultants. In future there will be the problem of managing a rapidly growing telemedicine network.

    The projected increase in diabetes in the United States and worldwide has created a need for broad-based, inexpensive screening for diabetic retinopathy (DR), an eye disease which can lead to vision impairment. A telemedicine network with retina cameras and automated quality control, physiological feature location, and lesion / anomaly detection is a low-cost way of achieving broad-based screening. In this work we report on the effect of quality estimation on an optic nerve (ON) detection method with a confidence metric. We report on an improvement of the fusion technique using a data set from an ophthalmologists practice then show the results of the method as a function of image quality on a set of images from an on-line telemedicine network collected in Spring 2009 and another broad-based screening program. We show that the fusion method, combined with quality estimation processing, can improve detection performance and also provide a method for utilizing a physician-in-the-loop for images that may exceed the capabilities of automated processing.

    The use of telemedicine appears particularly promising in cardiovascular disease, because the cost/effectiveness ratio of an early, tailored intervention, in terms of life-saving and functional recovery is demonstrated. Boario Home Care project was born in 1998, with the aim of applying the new models of disease management and the new technology on the territory. In the first phase the project was to realize a telematic network for the General Practitioners in a mountain territory; In the second phase the project was extended to the regional and then national territory and the number of enrolled GPs increased. In the third phase, that is nowadays, the structure of the Service Center has been implemented with new broad band technologies (HDLS) and with an innovative teleworking model has been adopted for the professional figures involved. Four different types of services are now available: General Practitioners, Home Telenursing for chronic patients, Tele-diagnosis for palpitations and Call Center Services for hospitals. In conclusion, Boario Home Care project has reached its maturity and many results even if we can consider them preliminary in the field of Telemedicine. Boario Home Care project won e-health Awards with the honourable mention and it was presented at the "eHealth 2003: ICT for Health" in Brussels, Belgium.

  9. Scheduling in Sensor Grid Middleware for Telemedicine Using ABC Algorithm

    Full Text Available Advances in microelectromechanical systems (MEMS and nanotechnology have enabled design of low power wireless sensor nodes capable of sensing different vital signs in our body. These nodes can communicate with each other to aggregate data and transmit vital parameters to a base station (BS. The data collected in the base station can be used to monitor health in real time. The patient wearing sensors may be mobile leading to aggregation of data from different BS for processing. Processing real time data is compute-intensive and telemedicine facilities may not have appropriate hardware to process the real time data effectively. To overcome this, sensor grid has been proposed in literature wherein sensor data is integrated to the grid for processing. This work proposes a scheduling algorithm to efficiently process telemedicine data in the grid. The proposed algorithm uses the popular swarm intelligence algorithm for scheduling to overcome the NP complete problem of grid scheduling. Results compared with other heuristic scheduling algorithms show the effectiveness of the proposed algorithm.

    Telemedicine carries the potential of improving accessibility to health services, especially for disabled people. To assess the health-related outcomes of short-term implementation of telemedicine (telemed) for MS patients. A prospective study of 40 MS patients divided into a control group and a telemed group was conducted, in two stages: A. Six months' follow-up for measurement of baseline health-related variables; B. Implementation stage, adding home telecare to the telemed group. A Health Value Compass was applied to assess the outcomes of home telecare implementation. Clinical status, cost data, patients' self-assessment of Health Related Quality of Life (HRQoL) and satisfaction with telecare were studied. Patients in the telemed group demonstrated improved clinical outcome measured by symptoms severity. There was a decrease of at least 35% in the medical costs for 67% of the telemed group patients. Satisfaction with telecare was high and most patients would recommend this service to others. The present pilot study, applying Health Value Compass-based analysis, suggests that telecare is a powerful tool for monitoring MS patients at home, carries the potential to improve health care while reducing costs, and should be considered for implementation as part of the management of chronic neurological diseases.

    The adoption of telemedicine into mainstream health services has been slower than expected. Many telemedicine projects tend not to progress beyond the trial phase; there are a large number of pilot or project publications and fewer 'service' publications. This issue has been noted since 1999 and continues to be acknowledged in the literature. While overall telemedicine uptake has been slow, some services have been successful. The reporting and evaluation of these successful services may help to improve future uptake and sustainability. The aim of this literature review was to identify peer-reviewed publications of deployed telemedicine services in hospital facilities; and to report, and appraise, the methodology used to evaluate these services. Computerised literature searches of bibliographic databases were performed using the MeSH terms for "Telemedicine" and "Hospital Services" or "Hospital", for papers published up to May 2016. A total of 164 papers were identified, representing 137 telemedicine services. The majority of reported telemedicine services were based in the United States of America (n=61, 44.5%). Almost two thirds of the services (n=86, 62.7%) were delivered by real time telemedicine. Of the reviewed studies, almost half (n=81, 49.3%) assessed their services from three different evaluation perspectives: clinical outcomes, economics and satisfaction. While the remaining half (n=83, 50.6%) described their service and its activities without reporting any evaluation measures. Only 30 (18.2%) studies indicated a two-step implementation and evaluation process. There was limited information in all reported studies regarding description of a structured planning strategy. Our systematic review identified only 137 telemedicine services. This suggests either telemedicine service implementation is still not a part of mainstream clinical services, or it is not being reported in the peer-reviewed literature. The depth and the quality of information were variable

    2009-12-01

    The aim of the study is codify both a methodological and communication standard based on teleassistance, and the emergencies that can be treated from a remote location along with the related clinical applications, limitations, medicolegal considerations and the patients' opinion on this new opportunity of assistance. To codify a distance communication method, ten young patients aged 10-16 years, equipped with a mobile videophone and after clear instructions, asked the advice of the orthodontic specialist to deal with minor orthodontic emergencies. Upon completion of the treatment they filled out a questionnaire on satisfaction level and difficulties encountered with the use of this technology. Most of the orthodontic emergencies can be solved at home: rubber ligature displacement, discomfort due to the appliance, irritation of cheeks. Those patients who used the videophone to handle the orthodontic emergencies considered it an easy and useful method, possibly due to the young age of the subjects involved, who are familiar with the new technologies. Telecommunications applied to medicine and dentistry is currently a subject of topical interest. The most developed countries are investing resources in order to improve assistance and communication between physicians and patients and among specialists. The possibility of sharing videos and images is particularly useful in the orthodontic field, as minor emergencies can be solved easily at home, reassuring patient and parents on one hand, and limiting visits to the dental office to cases of real need.

    Healthcare systems require a paradigm shift in the way healthcare services are delivered to counteract demographic changes in patient populations, expanding technological developments and the increasing complexity of healthcare. Participatory design (PD) is a methodology that promotes the participation of users in the design process of potential telehealth applications. A PD project can be divided into four phases including: the identification and analysis of participant needs; the generation of ideas and development of prototypes; testing and further development of prototypes; and evaluation. PD is an iterative process where each phase is planned by reflecting on the results from the previous phase with respect to the participants' contribution. Key activities of a PD project include: fieldwork; literature reviewing; and development and testing. All activities must be applied with a participatory mindset that will ensure genuine participation throughout the project. Challenges associated with the use of PD include: the time required to properly engage with participants; language and culture barriers amongst participants; the selection of participants to ensure good representation of the user group; and empowerment. PD is an important process, which is complemented by other evaluation strategies that assess organisational requirements, clinical safety, and clinical and cost effectiveness. PD is a methodology which encourages genuine involvement, where participants have an opportunity to identify practical problems and to design and test technology. The process engages participants in storytelling, future planning and design. PD is a multifaceted assessment tool that helps explore more accurately clinical requirements and patient perspectives in telehealth.

  15. Access to expert stroke care with telemedicine: REACH MUSC

    Full Text Available Stroke is a leading cause of death and disability, and rtPA can significantly reduce the long-term impact of acute ischemic stroke (AIS if given within 3 hours of symptom onset. South Carolina is located in the stroke belt and has a high rate of stroke and stroke mortality. Many small rural SC hospitals do not maintain the expertise needed to treat AIS patients with rtPA. MUSC is an academic medical center using REACH MUSC telemedicine to deliver stroke care to 15 hospitals in the state, increasing the likelihood of timely treatment with rtPA. The purpose of this study is to determine the increase in access to rtPA through the use of telemedicine for AIS in the general population and in specific segments of the population based on age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality.We used a retrospective cross-sectional design examining Census data from 2000 and Geographic Information Systems (GIS analysis to identify South Carolina residents that live within 30 or 60 minutes of a Primary Stroke Center (PSC or a REACH MUSC site. We include all South Carolina citizens in our analysis and specifically examine the population’s age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality. Our sample includes 4,012,012 South Carolinians. The main measure is access to expert stroke care at a Primary Stroke Center (PSC or a REACH MUSC hospital within 30 or 60 minutes. We find that without REACH MUSC, only 38% of the population has potential access to expert stroke care in SC within sixty minutes given that most PSCs will maintain expert stroke coverage. REACH MUSC allows 76% of the population to be within sixty minutes of expert stroke care, and 43% of the population to be within 30 minute drive time of expert stroke care. These increases in access are especially significant for groups that have faced disparities in care and high rates of AIS. The use of telemedicine can

    2000-01-01

    In 1999 a national study of telemedicine in Australia led to the promotion of the concept of 'e-health', the health sector's equivalent of 'e-commerce'. A new study explored the view that, with the convergence of technologies and the consequent increase in ability to perform multiple functions with those technologies, it is unwise to promote telemedicine in isolation from other uses of technologies in health-care. The major sources of information for the study were the presentations and discussions at five national workshops held to discuss the findings of the original report on telemedicine. Nineteen case studies were identified. The case studies showed that with the convergence of technologies telehealth is becoming part of e-health. The cost-effectiveness of both telehealth and telemedicine improves considerably when they are part of an integrated use of telecommunications and information technology in the health sector.

  1. Reliability associated with the Roter Interaction Analysis System (RIAS) adapted for the telemedicine context.

    This study's purpose was to adapt the Roter Interaction Analysis System (RIAS) for telemedicine clinics and to investigate the adapted measure's reliability. The study also sought to better understand the volume of technology-related utterance in established telemedicine clinics and the feasibility of using the measure within the telemedicine setting. This initial evaluation is a first step before broadly using the adapted measure across technologies and raters. An expert panel adapted the RIAS for the telemedicine context. This involved accounting for all consultation participants (patient, provider, presenter, family) and adding technology-specific subcategories. Ten new and 36 follow-up telemedicine encounters were videotaped and double coded using the adapted RIAS. These consisted primarily of follow-up visits (78.0%) involving patients, providers, presenters, and other parties. Reliability was calculated for those categories with 15 or more utterances. Traditional RIAS categories related to socioemotional and task-focused clusters had fair to excellent levels of reliability in the telemedicine setting. Although there were too few utterances to calculate the reliability of the specific technology-related subcategories, the summary technology-related category proved reliable for patients, providers, and presenters. Overall patterns seen in traditional patient-provider interactions were observed, with the number of provider utterances far exceeding patient, presenter, and family utterances, and few technology-specific utterances. The traditional RIAS is reliable when applied across multiple participants in the telemedicine context. Reliability of technology-related subcategories could not be evaluated; however, the aggregate technology-related cluster was found to be reliable and may be especially relevant in understanding communication patterns with patients new to the telemedicine setting. Use of the RIAS instrument is encouraged to facilitate comparison

  2. Robust tissue classification for reproducible wound assessment in telemedicine environments

    2010-04-01

    In telemedicine environments, a standardized and reproducible assessment of wounds, using a simple free-handled digital camera, is an essential requirement. However, to ensure robust tissue classification, particular attention must be paid to the complete design of the color processing chain. We introduce the key steps including color correction, merging of expert labeling, and segmentation-driven classification based on support vector machines. The tool thus developed ensures stability under lighting condition, viewpoint, and camera changes, to achieve accurate and robust classification of skin tissues. Clinical tests demonstrate that such an advanced tool, which forms part of a complete 3-D and color wound assessment system, significantly improves the monitoring of the healing process. It achieves an overlap score of 79.3 against 69.1% for a single expert, after mapping on the medical reference developed from the image labeling by a college of experts.

    Telemedicine has the potential to increase access to both clinical consultation and continuing medical education in Cambodia. We present a Cambodian surgical centre's experience with a collaboration in which complicated orthopaedic cases were presented to a panel of consultants using free online videoconferencing software, providing a combined opportunity for both continuing education and the enhancement of patient care. Effects of the case conference on patient care were examined via a retrospective review and clinician perspectives were elicited via a qualitative survey. The case conference altered patient care in 69% of cases. All Cambodian staff reported learning from the conference and 78% reported changes in their care for patients not presented at the conference. Real-time videoconferencing between consultants in the developed world and physicians in a developing country may be an effective, low-cost and easily replicable means of combining direct benefits to patient care with continuing medical education.

    Cloud-based videoconferencing versus traditional systems are described for possible use in telemedicine and distance learning. Differences between traditional and cloud-based videoconferencing systems are examined, and the methods for identifying and testing systems are explained. Findings are presented characterizing the cloud conferencing genre and its attributes versus traditional H.323 conferencing. Because the technology is rapidly evolving and needs to be evaluated in reference to local needs, it is strongly recommended that this or other reviews not be considered substitutes for personal hands-on experience. This review identifies key attributes of the technology that can be used to appraise the relevance of cloud conferencing technology and to determine whether migration from traditional technology to a cloud environment is warranted. An evaluation template is provided for assessing systems appropriateness.

    The Final Report on the U.S.-U.S.S.R. Telemedicine Consultation Spacebride to Armenia and Ufa is presented. The goal of this activity was to provide expert medical consultation to the Armenian medical personnel in the areas of plastic and reconstructive surgery, physical and psychological rehabilitation, public health, and epidemiology following the devastating earthquake in Dec. 1988. The U.S. and U.S.S.R. implementation teams developed new standards for medical information transmittal as well as protocols and schedules on how to conduct medical consultations. The consultations were provided to the Republic Diagnostic Center in Yerevan, U.S.S.R. by four U.S. medical centers: University of Utah/LDS Hospital, University of Texas, Maryland Institute for Emergency Medical Service Systems, and Uniformed Services University of the Health Sciences.

  6. Telemedicine in diabetic retinopathy: Access to rural India

    Directory of Open Access Journals (Sweden)

    Taraprasad Das

    2016-01-01

    Full Text Available Diabetic retinopathy (DR is a growing concern in India. The first step in management of DR is timely screening. With 10% prevalence in rural India, 11 million people are likely to have DR by the year 2030. With limited resources and skilled manpower, it will not be possible to have routine eye examination to identify and treat these patients on a regular basis. Telemedicine is a possible answer in these situations where patients could be remotely screened and appropriately advised. With the advent of several technological advances such as low cost hand-held nonmydriatic camera, increased capabilities of the smartphones to take external eye and retinal photographs coupled with improving broadband connectivity; teleophthalmology in the management of DR could be a reality in the not too distant future.

  7. Legal and ethical issues in telemedicine and robotics.

    Science.gov (United States)

    Dickens, B M; Cook, R J

    2006-07-01

    Modern medical concerns with telemedicine and robotics practiced across national or other jurisdictional boundaries engage the historical, complex area of law called conflict of laws. An initial concern is whether a practitioner licensed only in jurisdiction A who treats a patient in jurisdiction B violates B's laws. Further concerns are whether a practitioner in A who violates a contract or treats a patient in B negligently incurs liability in B, A, or both, and, if treatment lawful in A is unlawful in B, whether the practitioner commits a crime. Judicial procedures are set by courts in which proceedings are initiated, but courts may decline jurisdiction due to inconvenience to parties. If courts accept jurisdiction, they may apply their own substantive legal rules, but may find that the rules of a conflicting jurisdiction should apply. Cross-border care should not change usual medical ethics, for instance on confidentiality, but may mitigate or aggravate migration of specialists.

    1997-01-01

    Telemedicine dates to the days of "wireless telegraphy". As an "extraordinary" arrangement for medical services delivered at time of need, telemedicine has thus far escaped the developments that have taken place over the last 50 years in the areas of medical liability, safety and confidentiality. Today, however, telemedicine is also used to increase quality and cost effectiveness of healthcare provision. This trend is set by the U.S. where the U.S. federal government funds telemedicine at an annual rate of more than $100 million i.e., at a rate 30 times or more than what the EU does while state and local agency support and private business investment in telemedicine is 3 to 4 times larger than that of the U.S. federal government. In this respect it must be stressed that technology tends to satisfy the relevant demand for telecommunications. Telemedicine is used in diverse areas such as pathology, surgery, physical therapy, and psychiatry. It is expected to revolutionise health care in the coming decade and, therefore, it will certainly take into account requirements for medical liability, safety and confidentiality in the same way as traditional "establishment" medicine does.

    2015-12-01

    Telemedicine is a disruptive innovation within health care settings as consultations take place via audio-visual technology rather than traditional face-to-face. Specialist perceptions and experiences of providing audio-visual consultations in emergency situations, however, are not well understood. The aim of this exploratory study was to describe the experience of medical specialists providing acute stroke decision-making support via telemedicine. Data from the Victorian Stroke Telemedicine (VST) programme were used. The experiences of specialists providing an acute clinical telemedicine service to rural emergency departments were explored, drawing on disruptive innovation theory. Document analysis of programme consultation records, meeting minutes and in-depth individual interviews with three neurologists were analysed using triangulation. Since February 2014, 269 stroke telemedicine consultations with 12 neurologists have occurred. Retention on the roster has varied between 1 and >4 years. Overall, neurologists reported benefits of participation, as they were addressing health equity gaps for rural patients. Negative effects were the unpredictability of consultations impacting on their personal life, the mixed level of experience of colleagues initiating the consult and not knowing patient outcomes since follow-up communication was not routine. Insights into workforce experience and satisfaction were identified to inform strategies to support specialists to adapt to the disruptive innovation of telemedicine. © The Author(s) 2015.

    Commercial telemedicine systems are increasingly functional, incorporating video-conferencing capabilities, diagnostic peripherals, medication reminders, and patient education services. However, these systems (1) rarely utilize information architectures which allow them to be easily integrated with existing health information networks and (2) do not always protect patient confidentiality with adequate security mechanisms. Using object-oriented methods and software wrappers, we illustrate the transformation of an existing stand-alone telemedicine system into `plug-and-play' components that function in a distributed medical information environment. We show, through the use of open standards and published component interfaces, that commercial telemedicine offerings which were once incompatible with electronic patient record systems can now share relevant data with clinical information repositories while at the same time hiding the proprietary implementations of the respective systems. Additionally, we illustrate how leading-edge technology can secure this distributed telemedicine environment, maintaining patient confidentiality and the integrity of the associated electronic medical data. Information surety technology also encourages the development of telemedicine systems that have both read and write access to electronic medical records containing patient-identifiable information. The win-win approach to telemedicine information system development preserves investments in legacy software and hardware while promoting security and interoperability in a distributed environment.

  11. Assessment of Patients’ Perception of Telemedicine Services Using the Service User Technology Acceptability Questionnaire

    2016-06-01

    Full Text Available Introduction: The purpose of this paper is to assess if similar telemedicine services integrated in the management of different chronic diseases are acceptable and well perceived by patients or if there are any negative perceptions. Theory and methods: Participants suffering from different chronic diseases were enrolled in Veneto Region and gathered into clusters. Each cluster received a similar telemedicine service equipped with different disease-specific measuring devices. Participants were patients with diabetes (n = 163, chronic obstructive pulmonary disease (n = 180, congestive heart failure (n = 140 and Cardiac Implantable Electronic Devices (n = 1635. The Service User Technology Acceptability Questionnaire (SUTAQ was initially translated, culturally adapted and pretested and subsequently used to assess patients’ perception of telemedicine. Data were collected after 3 months and after 12 months from the beginning of the intervention. Data for patients with implantable devices was collected only at 12 months. Results: Results at 12 months for all clusters are similar and assessed a positive perception of telemedicine. The SUTAQ results for clusters 2 (diabetes, 5 (COPD and 7 (CHF after 3 months of intervention were confirmed after 12 months. Conclusions: Telemedicine was perceived as a viable addition to usual care. A positive perception for telemedicine services isn’t a transitory effect, but extends over the course of time.

Using object-oriented methods and software wrappers, we illustrate the transformation of an existing stand-alone telemedicine system into 'plug-and-play' components that function in a distributed medical information environment. We show, through the use of open standards and published component interfaces, that commercial telemedicine offerings which were once incompatible with electronic patient record systems can now share relevant data with clinical information repositories while at the same time hiding the proprietary implementations of the respective systems. Additionally, we illustrate how leading-edge technology can secure this distributed telemedicine environment, maintaining patient confidentiality and the integrity of the associated electronic medical data. Information surety technology also encourages the development of telemedicine systems that have both read and write access to electronic medical records containing patient-identifiable information. The win-win approach to telemedicine information system development preserves investments in legacy software and hardware while promoting security and interoperability in a distributed environment

    Surgical and nonsurgical specialists are highly centralized, making access to high-quality care difficult for many Americans. We explored the feasibility, benefits, preliminary outcomes, and patient satisfaction with a new type of health visit, in which a surgical oncologist used video telecommunication to manage and treat complex cancer diseases, including patients with severe comorbidities. Patients visited local VA medical centers throughout Florida to engage in video telecommunication visits with a centralized surgical oncologist in Miami, who directed their oncology treatment. The average length of stay and rate of unplanned readmission were calculated within each organ. The total mileage saved was calculated by subtracting the distance between the patient's home address and the local VA from the distance between the patient's home address and the Miami VA. Travel costs were determined by the VA's reimbursement of $0.415/mile for health-related travel and reimbursement of $150.00 for an overnight hotel stay. A Likert scale with both positively and negatively keyed questions was used to assess patient satisfaction. In 24 mo, seven unplanned readmissions occurred among 195 operations. Patients experienced an 80.7% reduction in travel distance and saved a total of 213,007.58 miles by visiting their local VA instead of the Miami VA. Survey results indicate that 86% of patients believed that the telemedicine program made medical care more accessible. The Specialist-Directed Telemedicine Model can save patients substantial time and money by not traveling to centralized areas, while delivering greater continuity of care and patient satisfaction.

    To develop, implement and evaluate a telemedicine model to reduce glaucoma blindness through the early detection of undiagnosed glaucoma in high-risk individuals. Prospective study, private ophthalmology practice and public outpatient clinics in Tasmania. One hundred and thirty-three individuals with primary open-angle glaucoma were invited to enrol their first-degree relatives (FDRs) to undergo an eye examination. Within the study period, 211 FDRs were available for examination. A registered nurse was trained to perform the required assessments. Clinical data were entered into a purpose-built database, converted to a portable document format and graded offsite by an ophthalmologist to determine the presence, absence or risk of developing glaucoma. Participants were notified of the grading result and recommendations for review. Incidence of undiagnosed glaucoma in a high-risk population. Previously undiagnosed glaucoma was identified in 5% of those examined. For every 19 participants screened, one new case of previously undiagnosed case of glaucoma was identified. Additionally 15% of participants showed suspicious signs of glaucoma, and 6% had ocular hypertension. A telemedicine model is an efficient method for screening, grading and notifying participants of examination results. Nurses can be adequately trained to undertake the initial screening examinations, with grading of the results performed offsite by a suitably qualified ophthalmologist. Targeted screening for glaucoma increases the yield of identifying individuals with undiagnosed glaucoma or those at greatest risk. Cost efficiencies for this model of glaucoma screening should be further explored and implemented to prevent blindness from familial glaucoma. © 2011 The Authors.

    Telemedicine networks are beginning to provide an avenue for conducting emergency medicine research, but using telemedicine to recruit participants for clinical trials has not been validated. The goal of this consent study was to determine whether patient comprehension of telemedicine-enabled research informed consent is noninferior to standard face-to-face (F2F) research informed consent. A prospective, open-label randomized controlled trial was performed in a 60,000-visit Midwestern academic emergency department (ED) to test whether telemedicine-enabled research informed consent provided noninferior comprehension compared with standard consent. This study was conducted as part of a parent clinical trial evaluating the effectiveness of 0.12% oral chlorhexidine gluconate in preventing hospital-acquired pneumonia among adult ED patients with expected hospital admission. Prior to being recruited into the study, potential participants were randomized in a 1:1 allocation ratio to consent by telemedicine versus standard F2F consent. Telemedicine connectivity was provided using a commercially available interface (REACH platform, Vidyo Inc.) to an emergency physician located in another part of the ED. Comprehension of research consent (primary outcome) was measured using the modified quality of informed consent (QuIC) instrument, a validated tool for measuring research informed consent comprehension. Parent trial accrual rate and qualitative survey data were secondary outcomes. A total of 131 patients were randomized (n = 64, telemedicine), and 101 QuIC surveys were completed. Comprehension of research informed consent using telemedicine was not inferior to F2F consent (QuIC scores 74.4 ± 8.1 vs. 74.4 ± 6.9 on a 100-point scale, p = 0.999). Subjective understanding of consent (p = 0.194) and parent trial study accrual rates (56% vs. 69%, p = 0.142) were similar. Telemedicine is noninferior to F2F consent for delivering research informed consent, with no detected

    possibilities of modern technology in addition to verbal exchange include visual and interactive "tele"-communication. This renders a new option to the physician, as without direct patient contact he is able to observe, counsel and actively interact - the latter even more so in the future. In oncology the increase of knowledge thus far has gone hand-in-hand with further specialization. This explains the difficulties one encounters in the correct evaluation of relevant data of one specific patient. Telemedicine will help to focus on the advantages of specialist knowledge by rendering access to all available data. These possibilities should furthermore be accessible during a consultation, an examination or in the course of a surgical intervention. Real-time modalities are referred to as telepresence and exceed by far a mere electronic version of the patient's medical folder. Especially in oncology, interdisciplinary collaboration is immensely important for successful therapy. Preoperative diagnostic data are still to be evaluated according to the intraoperative findings. At this decisive moment, it is necessary to involve specialists of other oncological disciplines. Real-time communication devices have to be present in order to transfer image data and clinical observations and ensure the best possible transmission quality to resident and geographically distant experts. With further technological perfection and widespread availability of interactive consultation, other applications include the "second opinion" in the daily routine. Another fascinating option in oncology is offered by visual computer simulation in virtual reality (VR). Medical data are visualized according to the human perception by the means of scenic simulation. From that point of view, VR technologies represent a practicable user interface between computer technology and the individual human being. Through VR, three-dimensional worlds containing virtual objects, which consist of computer-generated data, are

    Advances in medicine have largely followed advances in technology. Medical strides have been made when physicians and researchers have adapted growing science to target specific problems. A new medical field, telemedicine, has emerged that links physicians with colleagues and patients. Cell phone technology is affordable for almost everyone, and basic models include digital photography. We present a case series exhibiting the utility of digital pictures taken with patients' cell phones. Our patients had wound infections requiring daily intravenous antibiotics and dressing changes. In years past, these patients would have required prolonged hospitalizations. In the era of managed care, patients with these infections are discharged from the hospital, but close outpatient observation is required to monitor the wound. Our patients lived up to 8 hours away from the hospital. Daily appointments for wound checks in the clinic were not practical. Wounds were thus monitored via cell phone images without the inconvenience of travel and the expense of staying in a local hotel, along with leaving appointments in the clinic available for others with new neurosurgical issues. Wound evaluations were conducted with the cameras on patients' cell phones. These images were transmitted to the surgeon via text messaging and emails. This application of cell phone technology has been documented previously in the literature of other specialties and could attain greater stature as a legitimate method for close outpatient observation by neurosurgeons if medicolegal issues are addressed.

    The purpose of this investigation was to demonstrate the potential of remote, mobile telemedicine during a four-week, high-altitude mountaineering expedition to Mount Logan, Canada's highest summit. Using a mobile satellite terminal and a laptop computer (both powered by a photovoltaic solar panel), ECG tracings and blood pressure measurements, in addition to colour images, short-segment video and audio clips were transmitted during the course of the ascent. The data were transmitted via a mobile communications satellite to a ground station in Ottawa, a distance of over 4000 km. The data were then transferred to the public switched data network and delivered to the University of Ottawa Heart Institute for analysis. Similarly, data were transmitted from the ground station to the expedition team on Mount Logan throughout the ascent. Using this technique, medical diagnosis and emergency care can be facilitated in extreme and isolated locations lacking a telecommunications infrastructure. Such technology has applications in developing countries, disaster response efforts, remote civilian and military operations, and in space operations.

    MERMAID is an EU financed telemedicine project with global reach and 24-hour, multilingual capability. It aspires to provide a model for the provision of health care services based on the electronic transmission of medical information, via ISDN based videoconferencing. This model will not be limited to medical diagnostics but it will encompass all cases where the actual delivery of health care services involves a patient who is not located where the provider is. Its implementation requires the commissioning of an expensive telecommunications infrastructure and the exploration of a number of solutions. In fact, all categories of telemedical applications (audio and video conferencing, multimedia communications, flat file and image transfer with low, medium and high bandwidth data requirements) are considered while the full range of network choices (Digital land lines, Cellular/Wireless, Satellite and Broadband) are being tested in terms of cost/performance tradeoffs that are inherent to them and the developmental state each of these options occupies in their in its life cycle. Finally, out that MERMAID utilises advanced land based line transmission technologies to aid the remote patient by making available the specialist care that is best suited in the particular case.

    Early work has demonstrated the feasibility and acceptance of newborn resuscitation telemedicine programs (NRTPs). The technology requirements for providing this type of emergency telemedicine service are unclear. We hypothesized that during NRTP consults, a wired telemedicine cart would provide a more reliable and higher-quality user experience than a consumer-grade wireless tablet. In this retrospective observational study, six spoke sites used consumer-grade wireless tablets during preintervention and wired coder/decoder (CODEC)-based telemedicine carts during postintervention. Both technologies used the same videoconferencing software. After the telemedicine consult, providers completed surveys assessing connection reliability, user satisfaction, and audio and video quality using a 1-5 Likert scale. Preintervention, users completed 99 consults and 95 surveys. Postintervention, users completed 73 consults and 192 surveys. Successful connection on first attempt was significantly improved with the wired cart compared with the wireless tablet (82.7% vs. 69.5%, p = 0.01), and the percentage of consults complicated by an unplanned disconnection was reduced (6.4% vs. 14.7%, p = 0.02). User satisfaction and video and audio quality ratings were significantly higher for the wired cart. The wired telemedicine cart increased connection reliability, which is important given the critical nature and long duration of NRTP consults. Audio-video quality was also improved, allowing for better visualization of the neonate and communication with the care team. Consumer-grade wireless tablets did not meet the program's technical requirements. Wired telemedicine carts improved reliability, user satisfaction, and audio-video quality. Wired carts may not fully meet NRTP requirements because of cart size and limited mobility.

CGC services are typically centered in urban medical centers, leading to limited access to counseling in rural communities. Telemedicine has the potential to improve access to CGC, increase efficient use of genetic counselors, and improve patient care in rural communities. For telemedicine CGC to gain wide acceptance and implementation it needs to be shown that individuals who receive telemedicine CGC have high satisfaction levels and that CGC is cost-effective; however little research has been conducted to measure the impact of telemedicine CGC. This paper describes the design and methodology of a randomized controlled trial comparing telemedicine with in-person CGC. Measurement of patient satisfaction and effectiveness outcomes are described, as is measurement of costs that are included in an economic analysis.

    The use of information technology (IT) in health care has continuously increased. This includes software solutions for digitalisation, data storage and innovative approaches in diagnostics. The facilitation of the access to specific information, even by the patient, has changed daily clinical work. Patients inform themselves about symptoms, diagnostic methods and treatment options. This urge for information and the wish for the best treatment is summarised in the expression "patient empowerment". In some countries, the gap between do-it-yourself diagnosis and telemedicine via the telephone has already been closed. A sophisticated telemedical hotline may help to improve consultation and treatment of patients living in remote regions or rural communities. Traumatology telemedicine may also be used in trauma environments, such as disasters or mass casualties. Therefore, the purpose of this study was to assess the demand for e-health solutions among patients seeking the help of the emergency department in a trauma hospital. A total of 255 patients (age range 18 - 75 years) were included in the study and were surveyed with the use of a questionnaire. As regards personal data, the questionnaire asked the patient about their Internet habits and about interesting topics they had researched in the world wide web. However, the questionnaire was specifically designed to ask for potential benefits and the patient's expectations for e-health solutions. Expected weaknesses and procedures for telemedical services were also included in a subsection. 43.5% of the patient cohort were woman and 56.5% men. The average distance to the hospital was 39.86 km. 223 patients were insured by the governmental health service providers and 32 had private insurance coverage. Aside from online shopping and online banking, the search for health topics was most frequent. The greatest fear was the lack of personal contact to the doctor (71.2%). Patients were also concerned about the safety of

    This study was undertaken to determine if ALS patients evaluated via telemedicine received the same quality of care as patients evaluated by traditional face-to-face encounters. A retrospective cohort study design was used. Participants were patients diagnosed with ALS that received multidisciplinary care at the tertiary Cleveland VA ALS Centre between 1 March 2008- and 31 anuary 2015. Participants were not randomised, but chose telemedicine based on preference, disability level or distance from the clinic. Telemedicine in this study consisted of a video conferencing platform enabling remote rather than face-to-face encounters with participants. There was no significant association between receiving quality ALS care and the mode of care. There was a trend for telemedicine patients to utilise home health care less often than those that received clinic care (AOR 0.50; 95% CI 0.16-1.59). There was no significant difference in survival time between the two groups (log-rank test χ 2  = 3.62, df = 1, p = 0.05). Patients receiving telemedicine had a higher probability of remaining stable or having ALS care.

    Full Text Available In the recent years, people have been more inclined towards the use of technology to reduce human effort. Telemedicine is one such concept which has gained popularity among the people, providing them easy access to health care. Telemedicine refers to the concept of providing health care from a distance through an integrated approach using information and communication technology (ICT. India, being a geographically wide country has its difficulties when it comes to providing health care facilities to people belonging to the different regions. This is one of the few reasons why India is the best stage to introduce a concept like telemedicine. The use of this technology to counter the various challenges has been highly regarded and termed as something which can revolutionize the medical field. Integrating telemedicine with electronic health record (EHR, which is a digital document of a person’s medical history is said to be a perfect combination which can help improve clinical efficiency. The country has seen initiatives taken up by various organizations, with the main motive of connecting the rural to the urban. Through this paper, we have discussed the potential we have with this technology, and also propose an EHR integrated telemedicine model to make the best use of it in an emergency healthcare situation to help save lives. We have also touched a few factors which can help the government better the current health scenario.

It connects healthcare through vast distances which would benefit both patients and doctors. The aim of this questionnaire study was to evaluate the effects of telemedicine on patients and medical specialists. Methods: A cross-sectional study was conducted among 122 participants (71 patients and 51 doctors on satisfaction in quality of service, cost-effectiveness, and problems encountered in healthcare provided by the telemedicine in Apollo Tele Health Services, Hyderabad, Telangana, India. The data for each group were calculated and compared. Results: About 80% patients and all the doctors reported their satisfaction on the quality of treatment given through telemedicine. Approximately, 90% of the participants found telemedicine cost-effective and 61% of the doctors found an increase in patient's inflow apart for their regular practice. Problems encountered in telemedicine were 47% in technical issues and 39% in time scheduling by doctors and 31% of patients were uncomfortable to face the camera, and 24% had technical issues. Conclusions: The results of the present study showed that telemedicine in healthcare could prove to be useful to patients in distant regions and to rural doctors in India. In the near future, telemedicine can be considered as an alternate to face to face patient care.

    Full Text Available Reflectance confocal microscopy (RCM is an imaging device that permits non-invasive visualization of cellular morphology and has been shown to improve diagnostic accuracy of dermoscopically equivocal cutaneous lesions. The application of double reader concordance evaluation of dermoscopy-RCM image sets in retrospective settings and its potential application to telemedicine evaluation has not been tested in a large study population.To improve diagnostic sensitivity of RCM image diagnosis using a double reader concordance evaluation approach; to reduce mismanagement of equivocal cutaneous lesions in retrospective consultation and telemedicine settings.1000 combined dermoscopy-RCM image sets were evaluated in blind by 10 readers with advanced training and internship in dermoscopy and RCM evaluation. We compared sensitivity and specificity of single reader evaluation versus double reader concordance evaluation as well as the effect of diagnostic confidence on lesion management in a retrospective setting.Single reader evaluation resulted in an overall sensitivity of 95.2% and specificity of 76.3%, with misdiagnosis of 8 melanomas, 4 basal cell carcinomas and 2 squamous cell carcinomas. Combined double reader evaluation resulted in an overall sensitivity of 98.3% and specificity of 65.5%, with misdiagnosis of 1 in-situ melanoma and 2 basal cell carcinomas.Evaluation of dermoscopy-RCM image sets of cutaneous lesions by single reader evaluation in retrospective settings is limited by sensitivity levels that may result in potential mismanagement of malignant lesions. Double reader blind concordance evaluation may improve the sensitivity of diagnosis and management safety. The use of a second check can be implemented in telemedicine settings where expert consultation and second opinions may be required.

    Telehealth is a broad term used to describe the use of electronic or digital information and communications technologies to support clinical healthcare, patient and professional health related education, and public health and health administration. Telerehabilitation refers to the delivery of rehabilitation and habilitation services via information and communication technologies (ICT), also commonly referred to as" telehealth" technologies. Telerehabilitation services can include evaluation, assessment, monitoring, prevention, intervention, supervision, education, consultation, and coaching. Telerehabilitation services can be deployed across all patient populations and multiple healthcare settings including clinics, homes, schools, or community-based worksites. This document was adapted from the American Telemedicine Association's (ATA) "A Blueprint for Telerehabilitation Guidelines" (2010) and reflects the current utilization of telerehabilitation services. It was developed collaboratively by members of the ATA Telerehabilitation Special Interest Group, with input and guidance from other practitioners in the field, strategic stakeholders, and ATA staff. Its purpose is to inform and assist practitioners in providing effective and secure services that are based on client needs, current empirical evidence, and available technologies. Rehabilitation professionals, in conjunction with professional associations and other organizations are encouraged to use this document as a resource for developing discipline-specific standards, guidelines, and practice requirements.

    Bossen, Ann L; Kim, Heejung; Williams, Kristine N; Steinhoff, Andreanna E; Strieker, Molly

    Demographic aging of the world population contributes to an increase in the number of persons diagnosed with dementia (PWD), with corresponding increases in health care expenditures. In addition, fewer family members are available to care for these individuals. Most care for PWD occurs in the home, and family members caring for PWD frequently suffer negative outcomes related to the stress and burden of observing their loved one's progressive memory and functional decline. Decreases in cognition and self-care also necessitate that the caregiver takes on new roles and responsibilities in care provision. Smart technologies are being developed to support family caregivers of PWD in a variety of ways, including provision of information and support resources online, wayfinding technology to support independent mobility of the PWD, monitoring systems to alert caregivers to changes in the PWD and their environment, navigation devices to track PWD experiencing wandering, and telemedicine and e-health services linking caregivers and PWD with health care providers. This paper will review current uses of these advancing technologies to support care of PWD. Challenges unique to widespread acceptance of technology will be addressed and future directions explored.

    Full Text Available In Italy, the number of people living with diabetes is about 3.5 million (5.5% of the population, with an increase by about 60% in the last 20 years and with 1 person out of 3 older than 65 years. The Italian Health Service system estimates that 10 billion euros is spent annually on caring for patients with diabetes, a figure that increases yearly. No national data on prevalence and incidence of legal blindness in patients with diabetes and no national registry of patients with diabetic retinopathy (DR are currently available. However, the available epidemiological data (in several locations throughout the country are consistent with those reported in other European countries. The use of telemedicine for the screening of DR in Italy is confined to geographically limited locations. The available data in the literature on implementation and use of telematic screening proved to be successful from patient, caregiver, and authorities point of view. This review addresses the available epidemiological data on DR and telematic screening realities in Italy and thus may help in establishing a national screening program.

    This article analyzes the possibility of using social networks for teaching and learning telemedicine. The Telemedicine Laboratory is presented as a case study that offers a learning model supported by the development of a social network in a higher education environment. We performed a qualitative research study through an anonymous survey and participant observation. The results show that the Telemedicine Laboratory allows the generation of new knowledge from a holistic approach to reality, through communication and information technology, supported by the development of a social network. The presence of "invited experts" in the teaching and learning process and the linking of this process to problematic situations that members can "recognize" and perceive as true for their domain increase motivation and constitute success factors in the learning and teaching process.

    This study identified the readiness factors that may create challenges in the use of telemedicine among patients in northern Louisiana with cancer. To identify these readiness factors, the team of investigators developed 19 survey questions that were provided to the patients or to their caregivers. The team collected responses from 147 respondents from rural and urban residential backgrounds. These responses were used to identify the individuals' readiness for utilising telemedicine through factor analysis, Cronbach's alpha reliability test, analysis of variance and ordinary least squares regression. The analysis results indicated that the favourable factor (positive readiness item) had a mean value of 3.47, whereas the unfavourable factor (negative readiness item) had a mean value of 2.76. Cronbach's alpha reliability test provided an alpha value of 0.79. Overall, our study indicated a positive attitude towards the use of telemedicine in northern Louisiana.

    To determine the diagnostic accuracy of telemedicine in various clinical levels of diabetic retinopathy (DR) and diabetic macular oedema (DME). PubMed, EMBASE and Cochrane databases were searched for telemedicine and DR. The methodological quality of included studies was evaluated using the Quality Assessment for Diagnostic Accuracy Studies (QUADAS-2). Measures of sensitivity, specificity and other variables were pooled using a random effects model. Summary receiver operating characteristic curves were used to estimate overall test performance. Meta-regression and subgroup analyses were used to identify sources of heterogeneity. Publication bias was evaluated using Stata V.12.0. Twenty articles involving 1960 participants were included. Pooled sensitivity of telemedicine exceeded 80% in detecting the absence of DR, low- or high-risk proliferative diabetic retinopathy (PDR), it exceeded 70% in detecting mild or moderate non-proliferative diabetic retinopathy (NPDR), DME and clinically significant macular oedema (CSME) and was 53% (95% CI 45% to 62%) in detecting severe NPDR. Pooled specificity of telemedicine exceeded 90%, except in the detection of mild NPDR which reached 89% (95% CI 88% to 91%). Diagnostic accuracy was higher with digital images obtained through mydriasis than through non-mydriasis, and was highest when a wide angle (100-200°) was used compared with a narrower angle (45-60°, 30° or 35°) in detecting the absence of DR and the presence of mild NPDR. No potential publication bias was detected. The diagnostic accuracy of telemedicine using digital imaging in DR is overall high. It can be used widely for DR screening. Telemedicine based on the digital imaging technique that combines mydriasis with a wide angle field (100-200°) is the best choice in detecting the absence of DR and the presence of mild NPDR.

    The aim of the study presented in this article is to analyse the determinants of telemedicine use. To that end, the study makes two basic contributions. First, it considers six working hypotheses in the context of technology acceptance models (TAMs). Second, it uses data obtained for three samples of physicians from three different countries (Spain, Colombia and Bolivia). Obtaining and comparing evidence on an international scale allows determinants of telemedicine use to be evaluated across different contexts. In Bolivia, the survey was conducted in hospitals and health care centres of the urban and rural districts of the municipality of Sucre, in a population comprising a total of 350 physicians. In Spain, the survey population consisted of medical professionals of all profiles affiliated with health care within the Canary Islands Health Service, comprising a total of 356 physicians. Finally, in Colombia, it was conducted in the Society of Surgery Service at San José Hospital of Bogotá, in a population comprising a total of 184 physicians. Using an extended TAM and survey data from 510 physicians (113 in Spain, 118 in Colombia and 279 in Bolivia), binary logistic regression analysis was performed. In the three samples, it was found that the physician's level of information and communication technology (ICT) use in his/her personal life was the variable that had the highest explanatory power regarding telemedicine use. In the Spanish sample, the physicians' perceived ease-of-use of ICTs in clinical practice and propensity to innovate were the two other variables that determined telemedicine use, whereas in the Colombian and Bolivian samples, it was the level of optimism about ICTs. The results facilitated a more complete model that includes personal, usability, and innovatory aspects in the explanation of Telemedicine use in Spain, whereas the results for the Latin American samples indicated a more primary model in the explanation of Telemedicine use, which was

    To develop an integrated diabetic retinopathy screening program that uses telemedicine. In this evaluation of diagnostic technology, six telemedical screening units were established to cover all regions of Bahrain. The units were equipped with a digital fundus camera at the primary health care clinic. Fundus photographs were transmitted via the Internet to a centralized reading center. A retinal specialist at the reading center assessed the images. From 2003 to 2009, 17,490 diabetic patients were screened. Of the screened patients, 20% were diagnosed with diabetic retinopathy. Of these cases, 31% required treatment. Telemedicine-based screening program is a feasible and efficient means of detecting diabetic retinopathy and providing treatment.

    This is the first article in a Series on collaborative projects between European countries, relevant for general practice/family medicine and primary healthcare. Telemedicine, in particular the use of the Internet, videoconferencing and handheld devices such as smartphones, holds the potential for further strides in the application of technology for the delivery of healthcare, particularly to communities in rural and remote areas within and without the European Union where this study is taking place. The Northern Periphery Programme has funded the 'Implementing Transnational Telemedicine Solutions' (ITTS) project from September 2011 to December 2013, led by the Centre for Rural Health in Inverness, Scotland. Ten sustainable projects based on videoconsultation (speech therapy, renal services, emergency psychiatry, diabetes), mobile patient self-management (physical activity, diabetes, inflammatory bowel disease) and home-based health services (medical and social care emergencies, rehabilitation, multi-morbidity) are being implemented by the six partner countries: Scotland, Finland, Ireland, Northern Ireland, Norway and Sweden. In addition, an International Telemedicine Advisory Service, created for the project, provides business expertise and advice. Community panels contribute feedback on the design and implementation of services and ensure 'user friendliness'. The project goals are to improve accessibility of healthcare in rural and remote communities, reducing unnecessary hospital visits and travel in a sustainable way. Opportunities will be provided for comparative research studies. This article provides an introduction to the ITTS project and how it aims to fulfil these needs. The ITTS team encourage all healthcare providers to at least explore possible technological solutions within their own context.

    To describe the development of telemedicine capabilities-application of remote consultation and diagnostic techniques-and to evaluate the feasibility and practicality of such clinical outreach to rural and underserved communities with limited telecommunications infrastructures. In 1992, Mayo Foundation (Rochester, Minn, Jacksonville, Fla, and Scottsdale, Ariz), the National Aeronautics and Space Administration, and the Defense Advanced Research Projects Agency collaborated to create a complex network of fiberoptic landlines, video recording systems, satellite terminals, and specially developed data translators linking Mayo sites with other locations in the continental United States on an on-demand basis. The purpose was to transmit data via the asynchronous transfer mode (ATM) digital communications protocol over the Advanced Communications Technology Satellite. The links were intended to provide a conduit for transmission of data for patient-specific consultations between physicians, evaluation of medical imagery, and medical education for clinical staffs at remote sites. Low-data-rate (LDR) experiments went live late in 1993. Mayo Clinic Rochester successfully provided medical consultation and services to 2 small regional medical facilities. High-data-rate (HDR) experiments included studies of remote digital echocardiography, store-and-forward telemedicine, cardiac catheterization, and teleconsultation for congenital heart disease. These studies combined landline data transmission with use of the satellite. The complexity of the routing paths and network components, immaturity of available software, and inexperience with existing telecommunications caused significant study delays. These experiments demonstrated that next-generation satellite technology can provide batch and real-time imagery for telemedicine. The first-generation of the ATM and satellite network technology used in these experiments created several technical problems and inconveniences that should

    Machine translation is evolving quite rapidly in terms of quality. Nowadays, we have several machine translation systems available in the web, which provide reasonable translations. However, these systems are not perfect, and their quality may decrease in some specific domains. This paper examines the effects of different training methods when it comes to Polish-English Statistical Machine Translation system used for the medical data. Numerous elements of the EMEA parallel text corpora and not related OPUS Open Subtitles project were used as the ground for creation of phrase tables and different language models including the development, tuning and testing of these translation systems. The BLEU, NIST, METEOR, and TER metrics have been used in order to evaluate the results of various systems. Our experiments deal with the systems that include POS tagging, factored phrase models, hierarchical models, syntactic taggers, and other alignment methods. We also executed a deep analysis of Polish data as preparatory work before automatized data processing such as true casing or punctuation normalization phase. Normalized metrics was used to compare results. Scores lower than 15% mean that Machine Translation engine is unable to provide satisfying quality, scores greater than 30% mean that translations should be understandable without problems and scores over 50 reflect adequate translations. The average results of Polish to English translations scores for BLEU, NIST, METEOR, and TER were relatively high and ranged from 7058 to 8272. The lowest score was 6438. The average results ranges for English to Polish translations were little lower (6758-7897). The real-life implementations of presented high quality Machine Translation Systems are anticipated in general medical practice and telemedicine. Copyright © 2015. Published by Elsevier Ltd.

    To present the technical background and the development of a procedure that enriches the semantics of Health Level Seven version 2 (HL7v2) messages for software-intensive systems in telemedicine trauma care. This study followed a multilevel model-driven approach for the development of semantically interoperable health information systems. The Pre-Hospital Trauma Life Support (PHTLS) ABCDE protocol was adopted as the use case. A prototype application embedded the semantics into an HL7v2 message as an eXtensible Markup Language (XML) file, which was validated against an XML schema that defines constraints on a common reference model. This message was exchanged with a second prototype application, developed on the Mirth middleware, which was also used to parse and validate both the original and the hybrid messages. Both versions of the data instance (one pure XML, one embedded in the HL7v2 message) were equally validated and the RDF-based semantics recovered by the receiving side of the prototype from the shared XML schema. This study demonstrated the semantic enrichment of HL7v2 messages for intensive-software telemedicine systems for trauma care, by validating components of extracts generated in various computing environments. The adoption of the method proposed in this study ensures the compliance of the HL7v2 standard in Semantic Web technologies.

    Auditory-Verbal Therapy (AVT) is an effective early intervention for children with hearing loss. The Hear and Say Centre in Brisbane offers AVT sessions to families soon after diagnosis, and about 20% of the families in Queensland participate via PC-based videoconferencing (Skype). Parent and therapist satisfaction with the telemedicine sessions was examined by questionnaire. All families had been enrolled in the telemedicine AVT programme for at least six months. Their average distance from the Hear and Say Centre was 600 km. Questionnaires were completed by 13 of the 17 parents and all five therapists. Parents and therapists generally expressed high satisfaction in the majority of the sections of the questionnaire, e.g. most rated the audio and video quality as good or excellent. All parents felt comfortable or as comfortable as face-to-face when discussing matters with the therapist online, and were satisfied or as satisfied as face-to-face with their level and their child's level of interaction/rapport with the therapist. All therapists were satisfied or very satisfied with the telemedicine AVT programme. The results demonstrate the potential of telemedicine service delivery for teaching listening and spoken language to children with hearing loss in rural and remote areas of Australia.

    The aim of this study is to present a review based on the literature and proceedings from selected telemedicine conferences. The review was developed using the PRISMA framework. The Embase and PubMed (updated until July 13, 2015) literature databases were searched for telemedicine-related terms and Poland. The literature search identified 129 eligible articles in the databases and 85 in conference proceedings until July 2015. Articles measured as a number of contributions per year presented a similar rising, fluctuating and almost parallel pattern. Fifty-nine percent of the reviewed papers were published in impacted journals. Almost half of all publications presented original papers. The published articles concerned mostly cardiology (16%), family medicine (15%) and pathology (11%). Conference proceedings papers concerned orthopedics (29%, significantly more frequent; p < 0.001) and cardiology (14%). Scientific activity of researchers and practitioners in Poland in the field of telemedicine is not high, but it is increasing over time. There is a tendency to present the research rather in high-quality journals instead of conferences before publication. The occurrence of individual medical specialty telemedicine in Poland may reflect country-specific needs.

    The aim of this study was to examine the impact of a Web-based telemedicine system for monitoring glucose control in pregnant women with diabetes on healthcare visits, metabolic control, and pregnancy outcomes. A prospective, single-center, interventional study with two parallel groups was performed in Puerto Real University Hospital (Cadiz, Spain). Women were assigned to two different glucose monitoring groups: the control group (CG), which was managed only by follow-ups with the Gestational Diabetes Unit (GDU), and the telemedicine group (TMG), which was monitored by both more spaced GDU visits and a Web-based telemedicine system. The number of healthcare visits, degree of metabolic control, and maternal and neonatal outcomes were evaluated. One hundred four pregnant women with diabetes (77 with gestational diabetes, 16 with type 1 diabetes, and 11 with type 2 diabetes) were included in the TMG (n=40) or in the CG (n=64). There were no significant differences in mean glycated hemoglobin level during pregnancy or after delivery, despite a significantly lower number of visits to the GDU (3.2±2.3 vs. 5.9±2.3 visits; P3.0±1.7 visits; PWeb-based telemedicine system can be a useful tool facilitating the management of pregnant diabetes patients, as a complement to conventional outpatient clinic visits.

    To determine if mobile videoconferencing technology can facilitate the discharge of low-acuity patients receiving in-home care without compromising short-term health outcomes. A 6-month trial commenced in July 2015 with 345 patients considered unsuited to Criteria Led Discharge (CLD) receiving in-home care included as participants. Nurses providing clinical support to patients in their homes were supplied with a tablet computer (Apple iPad) with Internet connectivity (Telstra 4G Network) and videoconferencing software (Cisco Jabber for Telepresence). Device usage data combined with hospital admission records were collected to determine (a) instances where a telemedicine-facilitated discharge occurred and (b) if the accepted measure of short-term health outcomes (readmission within 28 days) was adversely affected by this alternative method. Telemedicine technology facilitated the discharge of 10.1% (n = 35) of patients considered unsuitable for CLD from the Hospital in the Home model during the trial period. Statistically insignificant differences in rates of readmission between patients discharged in person versus those participating in the telemedicine-supported model suggest that the clinical standards of the service have been maintained. The results of evaluating telemedicine support for nurses providing low-acuity in-home care indicate that patients may be discharged remotely while maintaining the existing clinical standards of the service.

    Racial and ethnic disparities have been previously reported in acute stroke care. We sought to determine the effect of telemedicine (TM) on access to acute stroke care for racial and ethnic minorities in the state of Texas. Data were collected from the US Census Bureau, The Joint Commission and the American Hospital Association. Access for racial and ethnic minorities was determined by summing the population that could reach a primary stroke centre (PSC) or telemedicine spoke within specified time intervals using validated models. TM extended access to stroke expertise by 1.5 million residents. The odds of providing 60-minute access via TM were similar in Blacks and Whites (prevalence odds ratios (POR) 1.000, 95% CI 1.000-1.000), even after adjustment for urbanization (POR 1.000, 95% CI 1.000-1.001). The odds of providing access via TM were also similar for Hispanics and non-Hispanics (POR 1.000, 95% CI 1.000-1.000), even after adjustment for urbanization (POR 1.000, 95% CI 1.000-1.000). We found that telemedicine increased access to acute stroke care for 1.5 million Texans. While racial and ethnic disparities exist in other components of stroke care, we did not find evidence of disparities in access to the acute stroke expertise afforded by telemedicine. © The Author(s) 2015.

  16. Evolving medical service in the information age: a legal analysis of applying telemedicine programs in Taiwan.

    Wu, Hsing-Hao

    2008-12-01

    In the face of the information age, Internet and telecommunication technologies have been widely applied in various settings. These innovational technologies have been used in the areas of e-commerce, long distance learning programs, entertainment, e-government, and so on. In recent years, the evolution of Internet technology is also pervading the health care industry. This dramatic trend may significantly alter traditional medical practice as well as the means of delivery of health care. The idea of telemedicine is to use modern information technology as a means or platform to deliver health care service in remote areas and to manage medical information in digitalized forms. The progress of developing telemedicine, however, is rather slow. The main reason for this slow progress is not technological but rather legal. Health care providers are reluctant to promote this innovation in medical service mainly due to uncertain legal consequences and ethical concerns. Although there are many legal challenges surrounding telemedicine, this note will examine major legal issues including licensure, malpractice liability, and privacy protection. Furthermore, I will discuss the potential of applying telemedicine programs in Taiwan's National Health Insurance Program (hereinafter referred to as NHI).

  17. How is Telemedicine perceived? A qualitative study of perspectives from the UK and India

    2011-01-01

    Background Improvements in communication and information technologies have allowed for the globalisation of health services, especially the provision of health services from other countries, such as the use of telemedicine. This has led countries to evaluate their position on whether and to what extent they should open their health systems to trade. This often takes place from the context of multi-lateral trade agreements (under the auspices of the World Trade Organisation), which is misplaced as a significant amount of trade takes place regionally or bi-laterally. We report here the results of a qualitative study assessing stakeholders' views on the potential for a bi-lateral trade relationship between India and the UK, where India acts as an exporter and the UK as an importer of telemedicine services. Methods 19 semi-structured interviews were carried out with stakeholders from India and the UK. The themes discussed include prospects on the viability of a bi-lateral relationship between the UK and India on telemedicine, current activities and operations, barriers, benefits and risks. Results The participants in general believed there were good prospects for telemedicine trade, and that this could bring benefits to "importing" countries in terms of cost-savings and faster delivery of care and to "exporting" countries in the form of foreign exchange and quality improvement. However, there were some concerns regarding quality of care, regulation, accreditation and data security. Conclusions There is potential for trade in this type of health services to succeed and bring about important benefits to the countries involved. However, issues around data security and accreditation need to be taken into consideration. Countries may wish to consider entering bi-lateral agreements, as they provide more potential to address the concerns and capitalise on the benefits. Finally, this paper concludes that more data should be collected, both on the volume of telemedicine trade

    Polish ageing society still experiences health-related problems and the increasing difficulties in receiving medical care. The initiation of telemedicine programmes can change this situation for better. The question arises if telemedicine is a solution that the elderly are willing to accept and take advantage of in order to raise their quality of life. Questionnaire based research was conducted in 2015 on a sample group of 312 seniors. The respondents completed the Diener Satisfaction with Life Scale (SWLS) and the subscale of Health States from Fragebogen zur Lebenszufriedenheit (FLZ) by Fahrenberg et al. Each participant gave their consent to take part in the research. SWLS presents a relatively stable value in the subsequent decades of being old (60-69 years M=21.93 SD=6.25; 70-79 years M=21.70 SD=5.52; 80+ M=21.38 SD=5.82). The health related quality of life (the FLZ subscale), varied in the analysed subgroups (F=7.783 p=0.000), and was related to comorbidity and polytherapy. A positive attitude towards telemedicine was expressed by 40% of those surveyed. However the seniors' need for telemedical services was more limited and did not exceed the 10%. In Poland in ageing there still dominates the experience of multiple ailments and polytherapy, something which justifies a search for new, easily accessible, and economically sound solutions for health care. Telemedicine is a promising solution although there is a need for concrete steps to be taken to raise willingness amongst geriatric patients to take advantage of telemedicine.

    Bruno Monteiro Tavares Pereira

    Full Text Available CONTEXT AND OBJECTIVE: Telehealth and telemedicine services are advancing rapidly, with an increasing spectrum of information and communication technologies that can be applied broadly to the population's health, and to medical education. The aim here was to report our institution's experience from 100 videoconferencing meetings between five different countries in the Americas over a one-year period. DESIGN AND SETTING: Retrospective study at Universidade Estadual de Campinas. METHODS: Through a Microsoft Excel database, all conferences in all specialties held at our institution from September 2009 to August 2010 were analyzed retrospectively. RESULTS: A total of 647 students, physicians and professors participated in telemedicine meetings. A monthly mean of 8.3 (± 4.3 teleconferences were held over the analysis period. Excluding holidays and the month of inaugurating the telemedicine theatre, our teleconference rate reached a mean of 10.3 (± 2.7, or two teleconferences a week, on average. Trauma surgery and meetings on patient safety were by far the most common subjects discussed in our teleconference meetings, accounting for 22% and 21% of the total calls. CONCLUSION: Our experience with telemedicine meetings has increased students' interest; helped our institution to follow and discuss protocols that are already accepted worldwide; and stimulated professors to promote telemedicine-related research in their own specialties and keep up-to-date. These high-technology meetings have shortened distances in our vast country, and to other reference centers abroad. This virtual proximity has enabled discussion of international training with students and residents, to increase their overall knowledge and improve their education within this institution.

    The objective of the RAFT-Altiplano project (RAFT: Réseau en Afrique Francophone pour la Télémédecine, or African Francophone Telemedicine Network) is to evaluate the viability, potential, and risks of implementing and developing a telemedicine network in the context of a developing country-specifically, the Altiplano region of Bolivia-to improve access to medical care and continuing education in a rural area. The activities described in this report took place between 2011 and 2013. Digital telemedicine equipment was donated to the health centers and a Microsoft®-based platform capable of integration with other technologies (using standardized formats) was developed to manage documents and clinical content electronically. Health professionals were trained in teleconsultation and the teleconsultation workflow was designed. The tele-education system used is Dudal, which requires only a small bandwidth. After three years of implementation, an organized working structure of teleconsultation and tele-education tools, adapted to the Latin American context, is now in place and connections have been established with hospitals, institutions, and health centers. The project has improved access to specialized medical care in remote health centers and third-level hospitals in urban areas, and it has become the foundation for development of the national project "TeleSalud for Bolivia" promoted by the Ministry of Health, which involves use of the new Bolivian satellite, Túpac Katari. It is viable to develop and set up telemedicine tools to serve the population in remote regions of Bolivia when they are made available to government and municipal health institutions and communication between them and the health centers takes place in a coordinated manner. The sharing of experiences, challenges, and risks encountered is very useful in designing and implementing the telemedicine project "TeleSalud for Bolivia" on a national scale.

    The objective of this study was to estimate travel-related and environmental savings resulting from the use of telemedicine for outpatient specialty consultations with a university telemedicine program. The study was designed to retrospectively analyze the telemedicine consultation database at the University of California Davis Health System (UCDHS) between July 1996 and December 2013. Travel distances and travel times were calculated between the patient home, the telemedicine clinic, and the UCDHS in-person clinic. Travel cost savings and environmental impact were calculated by determining differences in mileage reimbursement rate and emissions between those incurred in attending telemedicine appointments and those that would have been incurred if a visit to the hub site had been necessary. There were 19,246 consultations identified among 11,281 unique patients. Telemedicine visits resulted in a total travel distance savings of 5,345,602 miles, a total travel time savings of 4,708,891 minutes or 8.96 years, and a total direct travel cost savings of $2,882,056. The mean per-consultation round-trip distance savings were 278 miles, average travel time savings were 245 minutes, and average cost savings were $156. Telemedicine consultations resulted in a total emissions savings of 1969 metric tons of CO 2 , 50 metric tons of CO, 3.7 metric tons of NO x , and 5.5 metric tons of volatile organic compounds. This study demonstrates the positive impact of a health system's outpatient telemedicine program on patient travel time, patient travel costs, and environmental pollutants.

    In Brazil, the Program for Institutional Development of the Unified Healthcare System (PROADI-SUS) has implemented a telemedicine service for urgent situations and emergencies. It is delivered by a high-technology (HT) hospital to 15 remote healthcare units (RUs) in 11 different Brazilian states. The aim of this study was to investigate possible barriers and benefits in telemedicine service among these units. We performed a qualitative study on the perceptions of physicians involved in telemedicine service in their role as providers and consultants. An individual, semistructured recorded interview was conducted with 28 physicians (17 HT; 11 RU) encompassing telemedicine resources and interaction among HT and RU physicians. Data analysis was performed by Discourse of Collective Subject. We identified the following barriers in the telemedicine service: (1) lack of experience in the use of technology or the quality of the internet signal; (2) the multiplicity of different telemedicine platforms; (3) the quality of the image sent to the HT hospital; (4) the misunderstanding that telemedicine is a time-consuming technology instead of a resource that may help to save lives; (5) not feeling comfortable exposing doubts to other HT colleagues; (6) problems in the management of telemedicine use in the RUs; and (7) political and legal issues. However, important benefits in telemedicine service were also described. The structural barriers should be the target of hospital managers. Development of standard remote care protocols may increase the use of telemedicine and create new work routines. Given the relationship difficulties among the RU and HT doctors during telemedicine consultations, other meetings should be organized to allow more interpersonal interactions. These meetings may also have the goal of sharing outcome indicators of their joint activity in telemedicine to stimulate and make them aware of the benefits of their interaction.

  7. Patient and provider satisfaction with the use of telemedicine: Overview and rationale for cautious enthusiasm

    Directory of Open Access Journals (Sweden)

    Whitten P

    2005-01-01

    Full Text Available Telemedicine research addressing user satisfaction abounds in academic literature. Results from patient satisfaction studies indicate exceptionally high levels of perceived satisfaction, often above the rates of expected satisfaction for traditional forms of health delivery. Results from provider satisfaction studies are also generally quite positive; however, data from providers point to higher concerns with delivery barriers and challenges. Even though data from patient and provider satisfaction research suggests overwhelming optimism for this delivery modality, this paper urges cautious embracement of these results for several reasons. First, many of the studies exhibit serious methodological weaknesses related to design and data collection instruments. In addition, the construct of satisfaction is largely undefined and is not clear. Even recognizing these caveats, the results of the study do offer some evidence that patient satisfaction will not impede the deployment of telemedicine, but provider satisfaction merits additional study.

    Management of victims in a 'dirty bomb' incident requires communication between the physicians directly involved and experts in radiation medicine. Telemedicine is an excellent tool to support doctors--who may not have specific training in radiation medicine--in handling radiation casualties. We have successfully used telemedicine in an exercise of the Federal Police in Germany. Experts in radiation medicine were provided by the Bundeswehr Institute of Radiobiology. Simple PC-based videoconferencing equipment was used with a 128 kbit/s ISDN line. To facilitate a standardized approach, a new questionnaire for radiation accidents was developed and tested during the exercise. A special camera was used for capturing skin images. Advice for patient treatment and strategies for safeguarding personnel and the environment during the exercise was provided almost immediately.

    Acrophobia is an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used as a treatment. Lately the virtual reality technology has been applied to that kind of anxiety disorders. A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. Recently, the patient can take diagnose from a medical doctor in distance with the telemedicine system. The hospital and doctors can get the medical data, audio, video, signals in the actual examination room or operating room via a live interactive system. Audio visual and multimedia conference service, online questionary, ECG signal transfer system, update system are needed in this system. Virtual reality simulation system that composed with a position sensor, head mount display, and audio system, is also included in this telemedicine system. In this study, we tried this system to the acrophobia patient in distance. (author). 16 refs., 7 figs.

    In October 2015, the "Chinese American Physicians E-Hospital" celebrated its "grand opening" online. All physicians affiliated with this E-Hospital are bilingual Chinese American physicians, who provide services ranging from initial teleconsulting to international transfer and treatment in the United States. Such telemedicine platform for medical tourism not only saves the patients from the hassles of identifying and connecting with an appropriate health service provider but also minimizes the language and cultural barriers. As a growing number of patients from middle- and low-income countries travel to the United States (US) for medical care, we face promising opportunities as well as mounting challenges. The Centers for Disease Control (CDC) in the US has guidance for Americans seeking care overseas, but is not available for international patients seeking care in US. This article opens a dialogue on the challenges associated with flourishing medical tourism and telemedicine, including quality assessment, risk communication, ethical guidelines, and legal concerns.

    Full Text Available This study examined teleconsultants' specialty, practice setting, type of employment, years and training in telemedicine to evaluate the effect of these characteristics on diagnoses and treatment. A postuse survey was conducted during 1998–2003 (n=454 consultations in the University of Arkansas for Medical Sciences' Rural Hospital, Telehealth Project. There were 61 consultants who conducted the teleconsultations. The teleconsultants established a diagnosis in 121 consultations and reported a change in diagnoses in 29 consultations. The consultants established a treatment plan in 219 consultations and reported a change in the treatment plan in 100 consultations. Dermatologists were significantly more likely to establish (P<.01 and change (P=.005 the diagnosis and to establish a treatment plan (P=.03, when compared to all other specialties. Teleconsultants who were self-employed were significantly more likely to change the treatment plan (P=.012. The findings suggest that teleconsultants' characteristics can affect diagnoses and treatment in telemedicine.

    So far we have developed Emergency Telemedicine System (ETS) which is a robust system using heterogeneous networks. In disaster areas, however, ETS cannot be used if the primary network channel is disabled due to damages on the network infrastructures. Thus we designed network management software for disaster communication network by combination of Mobile Ad hoc Network (MANET) and Wireless LAN (WLAN). This software maintains routes to a Backbone Gateway Node in dynamic network topologies. In this paper, we introduce the proposed disaster communication network with management software, and evaluate its performance using ETS between Medical Center and simulated disaster areas. We also present the results of network performance analysis which identifies the possibility of actual Telemedicine Service in disaster areas via MANET and mobile network (e.g. HSDPA, WiBro).

  18. Telemedicine: The legal framework (or the lack of it) in Europe

    Science.gov (United States)

    Raposo, Vera Lúcia

    2016-01-01

    In the framework of European law telemedicine is, simultaneously, a health service and an information service, therefore, both regulations apply. In what concerns healthcare and the practice of medicine there are no uniform regulations at the European level. Concerning health services the most relevant achievement to regulate this domain is Directive 2011/24/EU. In what regards information and telecommunications we must have in consideration Directive 95/46/EU, Directive 2000/31/EC and Directive 2002/58/EC. However, many issues still lack uniform regulation, mainly the domain of medical liability and of medical leges artis. Probably such standardization will never take place, since the European Union does not have, until now, a common set of norms regarding tort and criminal liability, much less specific legal norms on medical liability. These gaps may jeopardize a truly European internal market in health services and hamper the development of telemedicine in the European zone. PMID:27579146

    Full Text Available OBJECTIVE To estimate rates of non-adherence to telemedicine strategies aimed at treating drug addiction. METHODS A systematic review was conducted of randomized controlled trials investigating different telemedicine treatment methods for drug addiction. The following databases were consulted between May 18, 2012 and June 21, 2012: PubMed, PsycINFO, SciELO, Wiley (The Cochrane Library, Embase, Clinical trials and Google Scholar. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the quality of the studies. The criteria evaluated were: appropriate sequence of data generation, allocation concealment, blinding, description of losses and exclusions and analysis by intention to treat. There were 274 studies selected, of which 20 were analyzed. RESULTS Non-adherence rates varied between 15.0% and 70.0%. The interventions evaluated were of at least three months duration and, although they all used telemedicine as support, treatment methods differed. Regarding the quality of the studies, the values also varied from very poor to high quality. High quality studies showed better adherence rates, as did those using more than one technique of intervention and a limited treatment time. Mono-user studies showed better adherence rates than poly-user studies. CONCLUSIONS Rates of non-adherence to treatment involving telemedicine on the part of users of psycho-active substances differed considerably, depending on the country, the intervention method, follow-up time and substances used. Using more than one technique of intervention, short duration of treatment and the type of substance used by patients appear to facilitate adherence.

    For the majority of preterm infants, the last weeks of hospital admission mainly concerns tube feeding and establishment of breastfeeding. Neonatal home care (NH) was developed to allow infants to remain at home for tube feeding and establishment of breastfeeding with regular home visits from neonatal nurses. For hospitals covering large regions, home visits may be challenging, time consuming, and expensive and alternative approaches must be explored. To identify parental needs when wanting to provide neonatal home care supported by telemedicine. The study used participatory design and qualitative methods. Data were collected from observational studies, individual interviews, and focus group interviews. Two neonatal units participated. One unit was experienced in providing neonatal home care with home visits, and the other planned to offer neonatal home care with telemedicine support. A total of 9 parents with preterm infants assigned to a neonatal home care program and 10 parents with preterm infants admitted to a neonatal unit participated in individual interviews and focus group interviews, respectively. Three overall themes were identified: being a family, parent self-efficacy, and nurse-provided security. Parents expressed desire for the following: (1) a telemedicine device to serve as a "bell cord" to the neonatal unit, giving 24-hour access to nurses, (2) video-conferencing to provide security at home, (3) timely written email communication with the neonatal unit, and (4) an online knowledge base on preterm infant care, breastfeeding, and nutrition. Our findings highlight the importance of neonatal home care. NH provides parents with a feeling of being a family, supports their self-efficacy, and gives them a feeling of security when combined with nursing guidance. Parents did not request hands-on support for infant care, but instead expressed a need for communication and guidance, which could be met using telemedicine.

    2017-06-01

    Telemedicine units and information technology systems provide special healthcare services to remote populations using telecommunication technology, in order to reduce or even remove the usual and typical face-to-face contact between doctor and patient. This innovative approach to medical care delivery has been expanding for several years and currently covers various medical specialties. To facilitate installation of telemedicine systems/units in Greek remote areas, this article presents results of a cost-benefit analysis for two Greek islands, Patmos and Leros, using specific economic criteria. Net present value (NPV), internal rate of return (IRR), and payback period were calculated, in order to monetize the economic benefits and the costs savings, estimate the depreciation of each project, and highlight the social benefits. Costs were reduced (through saved air medical transportations) by €19,005 for Patmos and €78,225 for Leros each year. NPV and IRR were positive; NPV was €29,608 for Patmos and €293,245 for Leros, and IRR was 21.5% for Patmos and 140.5% for Leros. Each project depreciated faster than the 5-year life-cycle period, and specifically in 3.13 years for Patmos and in 0.70 years for Leros. The establishment of telemedicine systems/units in Patmos and Leros was evaluated and assessed positively, with large savings, economical and social, gained by reducing or even removing the face-to-face contact between doctor and patient. Telemedicine systems/units seem to be a promising solution, especially in Greece, where the problem of primary healthcare services in remote/inaccessible areas is of great concern.

In-ambulance telemedicine, defined by live bidirectional audio-video between a patient and a neurologist in a moving ambulance and the automated transfer of vital parameters, is a promising new approach to speed up and improve the quality of acute stroke care. Currently, no evidence exists on the cost effectiveness of in-ambu...

    An increasing number of studies within the field of telemedicine and e-health are designed as noninferiority studies, aiming to show that the telemedicine/e-health solution is not inferior to the traditional way of treating patients. The objective is to review and sum up the status of noninferiority studies within this field, describing advantages and pitfalls of this approach. PubMed was searched according to defined criteria, and 16 relevant articles were identified from the period 2008-June 2011. Most of the studies were related to the fields of psychiatry and emergency medicine, and most were published in journals relating to these fields or in general scientific or general medicine journals. All the studies claimed to be noninferiority studies, but 7 out of 16 tested for statistical differences as a proxy of noninferiority. The methodological quality of the studies varied. We discuss optimal procedures for future noninferiority studies within the field of telemedicine and e-health and situations in which this approach is most appropriate.

    Full Text Available Background: The e-health and telemedicine have emerged as tools to facilitate access to health services, both populations far from the centres, and those who reside near them is not easily accessible or require constant controls by their professionals health traffickers. Objective: To reflect on the uses, progress and difficulties faced by Information and Communication Technologies (ICT as a strategy to bring health services to users. Methodology: qualitative hermeneutic research; advanced in two phases. The first, theoretical review by finding relevant articles in scientific databases. The second phase, critical analysis of literature found, in order to understand the dynamics generated from the use of ICT in the health sector, its current uses and prospected, and the risk that can generate its implementation for providers and patients. Results: The e-health and telemedicine have advanced in their development process andColombiahas not been outside, but there are still drawbacks of ethical, legal and operational order, which are not static and show great variation over time, becoming challenges are not independent but are associated with the dynamic progress of ICT. Conclusion: e-health and telemedicine are valid strategies to improve access to health services to communities. But require the development of processes to prevent, mitigate and / or exceed the inconveniences that may arise from its use.

    To analyze in-room video recordings of operating room (OR) to intensive care unit (ICU) handoffs to determine tempo and quality of team interactions on nights and weekends compared with weekdays, and to demonstrate how existing telemedicine technology can be used to evaluate handoffs. This prospective observational study of OR-to-ICU bedside handoffs was conducted in the surgical ICU of the Hospital of the University of Pennsylvania in July 2014-January 2015. Handoff video recordings were obtained for quality improvement purposes using existing telemedicine cameras. Evaluators used adapted validated in-person assessment measures to analyze basic characteristics and quality measures (timing, report types, report duration, presence of physical exam, teamwork skills, engagement, report delivery skills, listening skills, interruptions, unprofessional comments or actions). Sixteen weekday and 16 night and weekend handoffs were compared. There were no significant differences in basic characteristics. Most quality measures were similar on weekdays compared with nights and weekends. Surgeons demonstrated better report delivery skills and engagement on nights and weekends (P = .002 and P = .04, respectively), whereas OR anesthesiologists' scores were similar during both time frames. This study presents a novel approach of assessing handoff quality in OR-to-ICU handoffs using an existing telemedicine infrastructure. Using this approach, quality measures of night and weekend handoffs were found to be no worse-and sometimes better-than those during weekdays. Video analysis may emerge as an ideal unobtrusive quality improvement methodology to monitor handoffs and improve education and compliance with institutional handoff policies.

    Full Text Available Telemedicine can connect specialist health care providers with patients in remote and underserved areas. It is especially relevant in diabetes care, where a proliferation of treatment options has added further complexity to the care of an already complex, highly prevalent disease. Recent developments in health reform encourage delivery systems to use team-based models and engage patients in shared decision-making (SDM, where patients and providers together make health care decisions that are tailored to the specific characteristics and values of the patient. The goal of this project was to design, integrate, and evaluate a team-based, SDM approach delivered to patients with diabetes in a rural community, building upon the previously established telemedicine for reach, education, access, and treatment (TREAT model. Patients in this feasibility study demonstrated improvement in hemoglobin A1c values, and reported better understanding of diabetes. Providers reported the SDM aids increased cohesion among team members (including patients and facilitated patient education and behavioral goal setting. This project demonstrated that SDM could be integrated into the workflow of a telemedicine team visit with good provider and patient satisfaction.

    Since the first remote intubation with telemedicine guidance, wireless technology has advanced to enable more portable methods of telemedicine involvement in remote airway management. Three voice over Internet protocol (VoIP) services were evaluated for quality of image transmitted, data lag, and audio quality with remotely observed and assisted intubations in an academic emergency department. The VoIP clients evaluated were Apple (Cupertino, CA) FaceTime(®), Skype™ (a division of Microsoft, Luxembourg City, Luxembourg), and Tango(®) (TangoMe, Palo Alto, CA). Each client was tested over a Wi-Fi network as well as cellular third generation (3G) (Skype and Tango). All three VoIP clients provided acceptable image and audio quality. There is a significant data lag in image transmission and quality when VoIP clients are used over cellular broadband (3G) compared with Wi-Fi. Portable remote telemedicine guidance is possible with newer technology devices such as a smartphone or tablet, as well as VoIP clients used over Wi-Fi or cellular broadband.

    2017-08-01

    Background Previous reviews have investigated the effectiveness of telemedicine in the treatment of heart failure (HF). Dependent variables have included hospitalisations, mortality rates, disease knowledge and health costs. Few reviews, however, have examined the variable of health-related quality of life (QoL). Methods Randomised controlled trials comparing the delivery methods of any form of telemedicine with usual care for the provision of HF disease-management were identified via searches of all relevant databases and reference lists. Studies had to report a quantitative measure for mental, physical or overall QoL in order to be included. Results A total of 33 studies were identified. However, poor reporting of data resulted in the exclusion of seven, leaving 26 studies with 7066 participants. Three separate, random effects meta-analyses were conducted for mental, physical and overall QoL. Telemedicine was not significantly more effective than usual care on mental and physical QoL (standardised mean difference (SMD) 0.03, (95% confidence interval (CI) -0.05-0.12), p = 0.45 and SMD 0.24, (95% CI -0.08-0.56), p = 0.14, respectively). However, when compared to usual care, telemedicine was associated with a small significant increase in overall QoL (SMD 0.23, (95% CI 0.09-0.37), p = 0.001). Moderator analyses indicated that telemedicine delivered over a long-duration (≥52 weeks) and via telemonitoring was most beneficial. Conclusion Compared to usual care, telemedicine significantly increases overall QoL in patients receiving HF disease management. Statistically non-significant but nonetheless positive trends were also observed for physical QoL. These findings provide preliminary support for the use of telemedicine in the management of heart failure without jeopardising patient well-being.

    Auscultation is one of the most utilized physical examination procedures for listening to lung, heart and intestinal sounds during routine consults and emergencies. Heart and lung sounds overlap in the thorax. An algorithm was used to separate them based on the discrete wavelet transform with multi-resolution analysis, which decomposes the signal into approximations and details. The algorithm was implemented in software and in hardware to achieve real-time signal separation. The heart signal was found in detail eight and the lung signal in approximation six. The hardware was used to separate the signals with a delay of 256 ms. Sending wavelet decomposition data - instead of the separated full signa - allows telemedicine applications to function in real time over low-bandwidth communication channels.

    Full Text Available Abstract Background Improvements in communication and information technologies have allowed for the globalisation of health services, especially the provision of health services from other countries, such as the use of telemedicine. This has led countries to evaluate their position on whether and to what extent they should open their health systems to trade. This often takes place from the context of multi-lateral trade agreements (under the auspices of the World Trade Organisation, which is misplaced as a significant amount of trade takes place regionally or bi-laterally. We report here the results of a qualitative study assessing stakeholders' views on the potential for a bi-lateral trade relationship between India and the UK, where India acts as an exporter and the UK as an importer of telemedicine services. Methods 19 semi-structured interviews were carried out with stakeholders from India and the UK. The themes discussed include prospects on the viability of a bi-lateral relationship between the UK and India on telemedicine, current activities and operations, barriers, benefits and risks. Results The participants in general believed there were good prospects for telemedicine trade, and that this could bring benefits to "importing" countries in terms of cost-savings and faster delivery of care and to "exporting" countries in the form of foreign exchange and quality improvement. However, there were some concerns regarding quality of care, regulation, accreditation and data security. Conclusions There is potential for trade in this type of health services to succeed and bring about important benefits to the countries involved. However, issues around data security and accreditation need to be taken into consideration. Countries may wish to consider entering bi-lateral agreements, as they provide more potential to address the concerns and capitalise on the benefits. Finally, this paper concludes that more data should be collected, both on the

    To increase the effective use of thrombolytics for acute stroke, the expertise of vascular neurologists must be disseminated more widely. We prospectively assessed whether telemedicine (real-time, two-way audio and video, and digital imaging and communications in medicine [DICOM] interpretation) or telephone was superior for decision making in acute telemedicine consultations. From January, 2004, to August, 2007, patients older than 18 years who presented with acute stroke symptoms at one of four remote spoke sites were randomly assigned, through a web-based, permuted blocks system, to telemedicine or telephone consultation to assess their suitability for treatment with thrombolytics, on the basis of standard criteria. The primary outcome measure was whether the decision to give thrombolytic treatment was correct, as determined by central adjudication. Secondary outcomes were the rate of thrombolytic use, 90-day functional outcomes (Barthel index [BI] and modified Rankin scale [mRS]), the incidence of intracerebral haemorrhages, and technical observations. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00283868. 234 patients were assessed prospectively. 111 patients were randomised to telemedicine, and 111 patients were randomised to telephone consultation; 207 completed the study. Mean National Institutes of Health stroke scale score at presentation was 9.5 (SD 8.1) points (11.4 [8.7] points in the telemedicine group versus 7.7 [7.0] points in the telephone group; p=0.002). One telemedicine consultation was aborted for technical reasons, although it was included in the analyses. Correct treatment decisions were made more often in the telemedicine group than in the telephone group (108 [98%] vs 91 [82%], odds ratio [OR] 10.9, 95% CI 2.7-44.6; p=0.0009). Intravenous thrombolytics were used at an overall rate of 25% (31 [28%] telemedicine vs 25 [23%] telephone, 1.3, 0.7-2.5; p=0.43). 90-day functional outcomes were not

    Full Text Available Introduction. Telemedicine is promoted as a means to increase access to specialty medical care among the urban underserved, yet little is known about its acceptability among these populations. We used components of a diffusion of innovation conceptual framework to analyze preexperience perceptions about telemedicine to assess its appeal among urban underserved African Americans and Latinos. Methods. Ten focus groups were conducted with African American (=43 and Latino participants (=44 in both English and Spanish and analyzed for key themes. Results. Both groups perceived increased and immediate access to multiple medical opinions and reduced wait time as relative advantages of telemedicine. However, African Americans expressed more concerns than Latinos about confidentiality, privacy, and the physical absence of the specialist. This difference may reflect lower levels of trust in new health care innovations among African Americans resulting from a legacy of past abuses in the US medical system as compared to immigrant Latinos who do not have this particular historical backdrop. Conclusions. These findings have implications for important issues such as adoption of telemedicine, patient satisfaction, doctor-patient interactions, and the development and tailoring of strategies targeted to each of these populations for the introduction, marketing, and implementation of telemedicine.

    Despite the clear political will to promote telemedicine and the large number of initiatives, the incorporation of this modality in clinical practice remains limited. The objective of this study was to identify the barriers perceived by key professionals who actively participate in the design and implementation of telemedicine in a healthcare system model based on purchasing of healthcare services using providers' contracts. We performed a qualitative study based on data from semi-structured interviews with 17 key informants belonging to distinct Catalan health organizations. The barriers identified were grouped in four areas: technological, organizational, human and economic. The main barriers identified were changes in the healthcare model caused by telemedicine, problems with strategic alignment, resistance to change in the (re)definition of roles, responsibilities and new skills, and lack of a business model that incorporates telemedicine in the services portfolio to ensure its sustainability. In addition to suitable management of change and of the necessary strategic alignment, the definitive normalization of telemedicine in a mixed healthcare model based on purchasing of healthcare services using providers' contracts requires a clear and stable business model that incorporates this modality in the services portfolio and allows healthcare organizations to obtain reimbursement from the payer. 2010 SESPAS.

    The study of the adoption of information technology (IT) by individuals has taken two approaches, one emphasizing rationalistic goal-oriented behavior and the other focusing on poignant forces that influence an individual's reaction to a new IT. These approaches are not necessarily mutually exclusive. Individuals' acceptance and subsequent usage of a new IT is predicated on both. Additionally, the tendency in past studies has been to examine either the rational or the poignant factors in the context of a "resource-rich" environment-one in which there is an abundance of IT, adequate infrastructure, and a high level of acculturation to technology solutions. Consequently, there is a clear need for the examination of these factors in resource-poor environments, where assumptions on technology abundance and technology culturation do not hold. We empirically test a model that explains the intention of physicians in a resource-poor environment (epitomized by rural Ethiopia) to adopt telemedicine systems. This model integrates the rational factors driving goal-oriented behavior with the poignant/emotive factors that are an innate part of each adopter's reaction to the new technology. We use the model to expose salient contextual factors that explain the acceptance behavior of individuals toward complex information and communications technology (ICT) solutions and implications of these on the management of technology transfer initiatives in a resource-poor environment. The model is parsimonious, yet explains 28% of the variance in the intention to adopt telemedicine systems and 58% in perceived ease of use. The theoretical and practical implications of this model are discussed. Namely, Sub-Saharan African, in general, and Ethiopian culture, in particular, plays an integral role in the adoption of ICT solutions. Organizational positions and roles among physicians, clinical professionals, and superiors stand to impact the adoption of telemedicine and other healthcare

    Information on the impact of tele-intensive care on nursing and priority areas of nursing care is limited. To conduct a national benchmarking survey of nurses working in intensive care telemedicine facilities in the United States. In a 2-phased study, an online survey was used to assess nurses' perceptions of intensive care telemedicine, and a modified 2-round Delphi study was used to identify priority areas of nursing. In phase 1, most of the 1213 respondents agreed to strongly agreed that using tele-intensive care enables them to accomplish tasks more quickly (63%), improves collaboration (65.9%), improves job performance (63.6%) and communication (60.4%), is useful in nursing assessments (60%), and improves care by providing more time for patient care (45.6%). Benefits of tele-intensive care included ability to detect trends in vital signs, detect unstable physiological status, provide medical management, and enhance patient safety. Barriers included technical problems (audio and video), interruptions in care, perceptions of telemedicine as an interference, and attitudes of staff. In phase 2, 60 nurses ranked 15 priority areas of care, including critical thinking skills, intensive care experience, skillful communication, mutual respect, and management of emergency patient care. The findings can be used to further inform the development of competencies for tele-intensive care nursing, match the tele-intensive care nursing practice guidelines of the American Association of Critical-Care Nurses, and highlight concepts related to the association's standards for establishing and sustaining healthy work environments. ©2016 American Association of Critical-Care Nurses.

    To analyze reported complications and their treatment after a medical abortion with mifepristone and misoprostol provided by a telemedicine service to women living in Latin America. Observational study based on the registry of consultations in a telemedicine service. A total of 872 women who used the service in 2010 and 2011 participated in the study. The dependent variables were overall complications, hemorrhage, incomplete abortion, overall treatments, surgical evacuation, and antibiotics. Independent variables were age, area of residence, socioeconomic deprivation, previous children, pregnancies and abortions, and week of pregnancy. We fitted Poisson regression models with robust variance to estimate incidence ratios and 95% confidence intervals (95%CI). Complications were reported by 14.6% of the participants: 6.2% reported hemorrhage and 6.8% incomplete abortion. Nearly one-fifth (19.0%) received postabortion treatment: 10.9% had a surgical evacuation and 9.3% took antibiotics. Socioeconomic deprivation increased the risk of complications by 64% (95%CI: 15%-132%), and, among these, the risk of incomplete abortion by 82% (95%CI: 8%-206%) and the risk of surgical intervention by 62% (95%CI: 7%-144%). Previous pregnancies increased the risk of complications and, specifically, the risk of hemorrhage by 2.29 times (95%CI: 1.33-3.95%). Women with a pregnancy of 12 or more weeks had a 2.45 times higher risk of receiving medical treatment and a 2.94 times higher risk of taking antibiotics compared with women with pregnancies of 7 or less weeks. Medical abortion provided by telemedicine seems to be a safe and effective alternative in contexts where it is legally restricted. Copyright © 2014 SESPAS. Published by Elsevier Espana.

    Telemedicine is often seen as the solution to the challenge of providing health care for an increasing number of people with chronic conditions. Projects are often organised locally and based on the involvement of stakeholders with a wide range of backgrounds. It can be challenging to ensure that projects are based on previous experience and that they do not repeat previous studies. To better understand these challenges and current practice, we examined telemedicine projects funded in the 2008-2010 period to explore where, how and to what extent results from the projects were documented and disseminated. Public and private funds were contacted for information about telemedicine studies focusing on people residing in their homes. After an initial screening of titles and abstracts, 19 projects were identified. The managers of the projects were contacted and information about project results and dissemination were obtained. More than half of all projects were disseminated to professionals as well as to the public and used two-way communication. However, it was generally difficult to obtain an overview of the projects due to dynamic changes in names and scopes. We propose that the funding authorities require designs comprising proper evaluation models that will subsequently allow the investigators to publish their findings. Furthermore, a dissemination plan comprising both peers and other professions should be made mandatory. The investigators should ensure proper documentation and dissemination of changes both during and after the projects in order to ensure transparency, and national or international organisations should establish a database with relevant data fields. not relevant. not relevant.

    To describe methodology and screening results from the Philadelphia Telemedicine Glaucoma Detection and Follow-up Study. Screening program results for a prospective randomized clinical trial. Individuals were recruited who were African-American, Hispanic/Latino, or Asian over age 40 years; white individuals over age 65 years; and any ethnicity over age 40 years with a family history of glaucoma or diabetes. Primary care offices and Federally Qualified Health Centers were used for telemedicine (Visit 1). Two posterior fundus photographs and 1 anterior segment photograph were captured per eye in each participant, using a nonmydriatic, autofocus, hand-held fundus camera (Volk Optical, Mentor, Ohio, USA). Medical and ocular history, family history of glaucoma, visual acuity, and intraocular pressure measurements using the ICare rebound tonometer (ICare, Helsinki, Finland) were obtained. Images were read remotely by a trained retina reader and a glaucoma specialist. From April 1, 2015, to February 6, 2017, 906 individuals consented and attended Visit 1. Of these, 553 participants were female (61.0%) and 550 were African-American (60.7%), with a mean age of 58.7 years. A total of 532 (58.7%) participants had diabetes, and 616 (68%) had a history of hypertension. During Visit 1, 356 (39.3%) participants were graded with a normal image. Using image data from the worse eye, 333 (36.8%) were abnormal and 155 (17.1%) were unreadable. A total of 258 (28.5%) had a suspicious nerve, 62 (6.8%) had ocular hypertension, 102 (11.3%) had diabetic retinopathy, and 68 (7.5%) had other retinal abnormalities. An integrated telemedicine screening intervention in primary care offices and Federally Qualified Health Centers detected high rate of suspicious optic nerves, ocular hypertension, and retinal pathology.

    Full Text Available Jorge A Cuadros Optometry/Vision Science, University of California, Berkeley, CA, USA Abstract: Diabetes is the main cause of blindness among working age adults, although treatment is highly effective in preventing vision loss. Eye examinations are recommended on a yearly basis for most patients for timely detection of retinal disease. Telemedicine-based diabetic retinopathy screening (TMDRS programs have been developed to identify patients with sight-threatening diabetic eye disease because patients are often noncompliant with recommended live eye examinations. This article reviews the cost-effectiveness of the various forms of TMDRS. A review of relevant articles, mostly published since 2008, shows that societal benefits generally outweigh the costs of TMDRS. However, advances in technology to improve efficacy, lower costs, and broaden screening to other sight-threatening conditions, such as glaucoma and refractive error, are necessary to improve the sustainability of TMDRS within health care organizations. Patient satisfaction with these telemedicine programs is generally high. New models of shared care with primary care providers and staff are emerging to improve patient engagement and follow-up care when individuals are found to have sight-threatening eye disease. TMDRS programs are growing and provide valuable clinical benefit. The cost-utility is currently well proven in locations with limited access to regular eye care services, such as rural areas, poor communities, and prison systems; however, improvements over time are necessary for these programs to be cost-effective in mainstream medical settings in the future.

    Treatment nonadherence and clinical inertia perpetuate poor cardiovascular disease (CVD) risk factor control. Telemedicine interventions may counter both treatment nonadherence and clinical inertia. We explored why a telemedicine intervention designed to reduce treatment nonadherence and clinical inertia did not improve CVD risk factor control, despite enhancing treatment adherence versus usual care. In this analysis of a randomized trial, we studied recipients of the 12-month telemedicine intervention. This intervention comprised two nurse-administered components: (1) monthly self-management education targeting improved treatment adherence; and (2) quarterly medication management facilitation designed to support treatment intensification by primary care (thereby reducing clinical inertia). For each medication management facilitation encounter, we ascertained whether patients met treatment goals, and if not, whether primary care recommended treatment intensification following the encounter. We assessed disease control associated with encounters, where intensification was/was not recommended. We examined 455 encounters across 182 intervention recipients (100% African Americans with type 2 diabetes). Even after accounting for valid reasons for deferring intensification (e.g., treatment nonadherence), intensification was not recommended in 67.5% of encounters in which hemoglobin A1c was above goal, 72.5% in which systolic blood pressure was above goal, and 73.9% in which low-density lipoprotein cholesterol was above goal. In each disease state, treatment intensification was more likely with poorer control. Despite enhancing treatment adherence, this intervention was unsuccessful in countering clinical inertia, likely explaining its lack of effect on CVD risk factors. We identify several lessons learned that may benefit investigators and healthcare systems.

    Full Text Available Background: Healthcare Information Technology advances in the Information, Communication and Telecommunication (ICT sector have made telemedicine a common and alternate medical service delivery in remote areas. Indian Space and Research Organization (ISRO established village resource centers managed by Non-government Organizations (NGO’s all over the country in 2010. While ISRO provided satellite connectivity and required equipment for communication, tele-education, and telemedicine in Uttarakhand, Himalayan Institute Hospital Trust provided primary health care through tele-consultation to remote tribal hilly areas through village resource centers. This paper features the technical and financial challenges faced in providing tele-consultation. Methods: A cross-sectional study of 115 clients, 4 health supervisors and co-ordinating doctor from three districts was done using semi-structured questionnaires for interview. Parameters at both doctor’s and patients’ end for communication, costs involved, quality of doctor-patient interaction and patient satisfaction from Tele-consultation sessions were assessed. Results: Video quality was more satisfactory than audio. The physical presence of a doctor was felt necessary only in 33/115 (30% of the time. The average cost for telemedicine consultation works out to just Rs. 15 per patient. Around 48.7% of the queries were processed in less than 10 minutes of satellite time. Around 67% of the beneficiaries felt that their privacy was not maintained as per their expectations.  The request to extend the timing of the session was made by 85% of the clients. Conclusions: Long periods of non- connectivity due to satellite failure, lack of technical staff, lack of patient’s privacy during sessions, lack of income generation for self-sustainability, were the major challenges faced. However many patients benefitted, did not have to travel long distances for medical advice and easy follow ups were

    The high number of patients with uncontrolled hypertension is still a public health pattern. The e-health contains all electronic health services used in order to improve communication between all the different actors. In arterial hypertension, few data exists on the possibilities: 1/ for patients to easily e-transfer their results of home blood pressure measurement (HBPM); 2/ for practitioners to receive and assess these HBPM results. Furthermore, physician's reluctance is often reported as a constraint for telemedicine development. Thus, we aimed to collect data on technical equipment of physicians, and on their expectations about this new way of relationship. 57 physicians, hypertension specialists (36 ± 8 years old, 56% men, mostly (88%) hospital practitioners) completed a self-administered questionnaire. The prevalence of technical equipment is summarized in Table 1. 77.1% of physicians thought that telemedicine could improve the control of hypertension, 29.8% thought they could provide less frequent consultations to their patients and 24.5 % that HBPM information would contribute to the fight against inertia. 83.2% of physicians would agree that HBPM data be transferred to a non- medical staff, a nurse in most cases (59.5%). Finally, while 89.5% of physicians declared they support the development of telemedicine in their daily practice, 100% of them found 3 kinds of "limits" to this exchange method. The main obstacles were: budget (49%), lack of legal frame (43%), medical reluctance (42%), difficulties in accessing or in mastering informatics tool (38.5%), confidentiality (28%), absence of direct benefit (21%), patient reluctance (21%).(Figure is included in full-text article.) : The equipment of physicians in home or mobile devices appears no longer an obstacle for the development of a program dedicated to telemedicine. The majority of medical practitioners working in specialized hypertension department agreed with Internet e-transfer of HBPM data

    The morphology of Greece has a significant effect on the structure and operational characteristics of the Greek health care system. The remote location of many rural health care centers and the concentration of major hospitals in the few big cities have an effect on both the quality and availability of health care that is provided. We are developing a strategic plan that would allow hospitals and health care centers across Greece to exchange medical data in digital form and have access to telemedicine and teleconsulting facilities. Two pilot networks have been implemented. The first network is designed to allow for telemedicine and teleconsulting services in the island of Evia. The second pilot network is an Image Management and Communications Systems (IMAC) and was implemented in the Onassio Hospital in Athens. Results of the pilot demonstrators were evaluated and have been very promising for a scaled-up implementation of this pilot project. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam.

    Point of care ultrasound (POCUS) is a useful diagnostic tool in medicine. POCUS provides an easy and reproducible method of diagnosis where conventional radiologic studies are unavailable. Telemedicine is also a great means of communication between educators and students throughout the world. Implementing POCUS with didactics and hands-on training, using portable ultrasound devices followed by telecommunication training, will impact the differential diagnosis and patient management in a rural community outside the United States. This is an observational prospective study implementing POCUS in Las Salinas, a small village in rural western Nicaragua. Ultrasound was used to confirm a diagnosis based on clinical exam, or uncover a new, previously unknown diagnosis. The primary endpoint was a change in patient management. International sonographic instructors conducted didactic and practical training of local practitioners in POCUS, subsequently followed by remote guidance and telecommunication for 3 months. A total of 132 patients underwent ultrasound examination. The most common presentation was for a prenatal exam (23.5 %), followed by abdominal pain (17 %). Of the 132 patients, 69 (52 %) were found to have a new diagnosis. Excluding pregnancy, 67 patients of 101 (66 %) were found to have a new diagnosis. A change in management occurred in a total of 64 (48 %) patients, and 62 (61 %) after excluding pregnancy. Implementing POCUS in rural Nicaragua led to a change in management in about half of the patients examined. With the appropriate training of clinicians, POCUS combined with telemedicine can positively impact patient care.

    Our department is located in the Tsugaru district, which is famous for heavy snow fall, and the small number of neurosurgeon centers in the urban areas leads to an inadequate distribution of neurosurgeons for patients in this region. Such geographical and social constraints have made it difficult to offer sufficient neurosurgical care to all patients in the region. We describe the usefulness of a telemedicine triage system using an image transfer system in the treatment of neurosurgical emergent cases. Image transfer systems have been installed at our hospital and 11 regional hospitals in the Tsugaru district, and have been utilized for teleconsultation regarding neurosurgical patients via transferred computed tomography images since 1989. Consultations regarding 2,858 cases were directed to our department between 1989 and 2006, including 1,615 cases of stroke, 869 cases of head trauma, 97 cases of brain tumor, and 277 cases with other disorders. 84% of subarachnoid hemorrhage cases and 22% of head trauma cases needed emergent transfer. The state of consciousness in intracerebral hemorrhage, and the state of consciousness and time of consultation in head trauma were statistically significant factors for emergent transfer. The presert telemedicine triage system was useful for ensuring correct diagnosis and appropriate primary neurosurgical care in the regional hospitals without neurosurgical units, resulting in a reinforcement of the relationships among the regional hospitals and the efficient transfer of emergent neurosurgical patients.

    Given the difficulties encountered by Telemedicine for final incorporation into clinical practice and given the lack of scientific evidence regarding the most appropriate implementation strategies, it is necessary to collect and disseminate lessons gained from experience in its introduction and diffusion in our health system. The aim of this study is to identify the facilitators perceived by professionals who actively participate in the design and implementation of telemedicine projects in the health care system. Qualitative study of data from semi-structured interviews with 17 key informants belonging to different Catalan health organizations. The identified facilitators are grouped in four broad areas: a TM service that meets a need clearly perceived by practitioners; a core leadership with a clinical profile, managing an open, participatory and flexible model that takes into account the needs of professionals; the ability to establish partnerships with different stakeholders beyond the customer-supplier relationship; and the inclusion in the initial design of a strategy for sustainability and normalization. Understanding the facilitators and barriers that appear in the process of implementing TM experiences in health care organizations becomes an item of high value for its final introduction. An approach combining the evidence on clinical effectiveness and cost-benefit with lessons learned about the dynamics of implementation and normalization will allow for a holistic understanding of the adoption of the TM and provide guidance for improving its organizational management.

    To describe the expanding role of telemedicine in healthcare, the key criteria required for a successful device and program implementation, and the current and future role of home monitoring in ophthalmology. Expert perspective. Analysis with real-world interpretation of home monitoring technologies, including current adoption barriers and expanded future demands based on demographic and market forces. Remote patient monitoring represents a paradigm shift in the way physicians care for patients. Success depends on meeting several criteria, among which are a recognized value proposition to the physician, robust device performance validation, ease of use for the patient, reliability of connectivity, safe and secure data transmission, and economic feasibility. Ophthalmic diseases, such as age-related macular degeneration, glaucoma, and diabetic retinopathy, are ideal candidates for home monitoring practice integration. Established home monitoring technology is already facilitating early detection and improved visual outcomes for patients with age-related macular degeneration. Future innovation currently underway or on the horizon will continue to evolve and expand the footprint of telemedicine within ophthalmology. Home monitoring has the potential to enhance the patient-physician relationship and to positively impact visual acuity outcomes in ophthalmic diseases. Advances in technology, demographic shifts, market changes, and patient demand for personalized medicine will require physicians to embrace technology in new and diverse ways, perhaps facilitating widespread adoption of home monitoring technology platforms.

    The growing prevalence of obesity is paralleling a rise in the older adult population creating an increased risk of functional impairment, nursing home placement and early mortality. The Centers for Medicare and Medicaid recognized the importance of treating obesity and instituted a benefit in primary care settings to encourage intensive behavioral therapy in beneficiaries by primary care clinicians. This benefit covers frequent, brief, clinic visits designed to address older adult obesity. We describe the challenges in the implementation and delivery into real-world settings. The challenges in rural settings that have the fastest growing elderly population, high obesity rates, but also workforce shortages and lack of specialized services are emphasized. The use of Telemedicine has successfully been implemented in other specialties and could be a useful modality in delivering much needed intensive behavioral therapy, particularly in distant, under-resourced environments. This review outlines some of the challenges with the current benefit and proposed solutions in overcoming rural primary care barriers to implementation, including changes in staffing models. Recommendations to extend the benefit's coverage to be more inclusive of non-physician team members is needed but also for improvement in reimbursement for telemedicine services for older adults with obesity.

    Full Text Available Acute organophosphorous pesticide (OP poisoning kills a lot of people each year. Treatment of acute OP poisoning is of very difficult task and is a time taking event. Present day informatics methods (telemedicine, bioinformatics methods (data mining, molecular modeling, docking, cheminformatics, and nanotechnology (nanomedicine should be applied in combination or separately to combat the rise of death rate due to OP poisoning. Use of informatics method such as Java enabled camera mobiles will enable us early detection of insecticidal poisoning. Even the patients who are severely intoxicated (suicidal attempts can be diagnosed early. Telemedicine can take care for early diagnosis and early treatment. Simultaneously efforts must be taken with regard to nanotechnology to find lesser toxic compounds (use less dose of nanoparticle mediated compounds: nano-malathion as insecticides and find better efficacy of lesser dose of compounds for treatment (nano-atropine of OP poisoning. Nano-apitropine (atropine oxide may be a better choice for OP poisoning treatment as the anticholinergic agent; apitropine and hyoscyamine have exhibited higher binding affinity than atropine sulfate. Synthesis of insecticides (malathion with an antidote (atropine, apitropine in nanoscale range will prevent the lethal effect of insecticides.

    With the large number of aging individuals requiring screening of cognitive functions for dementing illnesses, there is a necessity for innovative evaluation approaches. One domain that should allow for online, at a distance, examination is speech and language dysfunction, if the auditory and visual transmission is of sufficient quality to allow adequate patient participation and reliable, valid interpretation of signs and symptoms (Duffy et al 1997). Examine the effectiveness of language assessment in mild Alzheimer's patients using telemedicine (TM) compared with traditional in-person (IP) assessment. Ten patients with mild Alzheimer's disease, enrolled at a Geriatric Memory Clinic received a battery of standard language tests under two conditions: face-to-face and via satellite TM. Comparison of TM and IP testing conditions were assessed within each for scores on each test in the two conditions. On each of the five language tasks, the Wilcoxon signed ranks test indicated no significant difference on performance between the TM and IP conditions for each participant. Overall acceptance of the TM evaluation in an elderly population was rated at a high level except for one individual. Telemedicine can improve access to speech and language evaluation services which is relevant to both dementia and other neurological diseases of the elderly. In particular, this specific assessment tool can be used to provide evaluations in under-served rural areas.

    Ensuring quality medical education in all the medical colleges across India based on uniform curriculum prescribed by a regulatory body and maintaining a uniform standard are dependent on availability of an excellent infrastructure. Such infrastructure includes qualified teachers, knowledge resources, learning materials, and advanced education technology, which is a challenge in developing countries due to financial and logistic constraints. Advancement in telecommunication, information science, and technology provides an opportunity to exchange knowledge and skill across geographically dispersed organizations by networking academic medical centers of excellence with medical colleges and institutes to practice distance learning using information and communication technology (ICT)-based tools. These may be as basic as commonly used Web-based tools or may be as advanced as virtual reality, simulation, and telepresence-based collaborative learning environment. The scenario in India is no different from any developing country, but there is considerable progress due to technical advancement in these sectors. Telemedicine and tele-education in health science, is gradually getting adopted into the Indian Health System after decade-long pilot studies across the country. A recent recommendation of the National Knowledge Commission, once implemented, would ensure a gigabyte network across all the educational institutions of the country including medical colleges. Availability of indigenous satellite communication technology and the government policy of free bandwidth provision for societal development sector have added strength to set up infrastructure to pilot several telemedicine educational projects across the country.

    Assessing both stroke patients and their CT scans by using a conventional videoconference system offers an interesting opportunity to improve stroke care in rural areas. However, until now there have been no studies to suggest whether this method is feasible in routine stroke management. Seven rural hospitals in the southern part of Germany in Swabia were connected to the stroke unit of Günzburg with the use of a videoconference link (Telemedicine in Stroke in Swabia [TESS] Project). The local physicians are free to present every admitted stroke patient to the Günzburg stroke expert, who can assess the clinical status and CT images, thereafter giving therapeutic recommendations. All teleconsultations are rated concerning transmission quality and relevance of telemedicine for stroke management. A total of 153 stroke patients were examined by teleconsultation. Mean age was 67.5 years. Eighty-seven patients had suffered an ischemic stroke, 9 had an intracerebral hemorrhage, and 17 suffered a transient ischemic attack. Forty patients were revealed to have a diagnosis other than stroke. Duration of teleconsultation was 15 minutes on average. User satisfaction was good concerning imaging and audio quality, and patient satisfaction was very good or good in all cases. Relevant contributions could be made in >75% of the cases concerning diagnostic workup, CT assessment, and therapeutic recommendations. Teleconsultation using a videoconference system seems to be a feasible and promising method to improve stroke care in rural areas where management in a stroke unit is hindered by long transportation distances.
