Computerised decision support systems are designed to support clinicians in making decisions and thereby enhance the quality and safety of care. We aimed to undertake an interpretative review of the empirical evidence on computerised decision support systems, their contexts of use, and summarise evidence on the effectiveness of these tools and insights into how these can be successfully implemented and adopted. We systematically searched the empirical literature to identify systematic literature reviews on computerised decision support applications and their impact on the quality and safety of healthcare delivery over a 13-year period (1997-2010). The databases searched included: MEDLINE, EMBASE, The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, The Cochrane Central Register of Controlled Trials, The Cochrane Methodology Register, The Health Technology Assessment Database, and The National Health Service (NHS) Economic Evaluation Database. To be eligible for inclusion, systematic reviews needed to address computerised decision support systems, and at least one of the following: impact on safety; quality; or organisational, implementation or adoption considerations. Our searches yielded 121 systematic reviews relating to eHealth, of which we identified 41 as investigating computerised decision support systems. These indicated that, whilst there was a lack of investigating potential risks, such tools can result in improvements in practitioner performance in the promotion of preventive care and guideline adherence, particularly if specific information is available in real time and systems are effectively integrated into clinical workflows. However, the evidence regarding impact on patient outcomes was less clear-cut with reviews finding either no, inconsistent or modest benefits. Whilst the potential of clinical decision support systems in improving, in particular, practitioner performance is considerable, such technology may

High-performance liquid chromatography (HPLC) coupled with high-resolution sector field ICP-MS was applied to the speciation of arsenic in environmental samples collected from the Moira watershed, Ontario, Canada. Arsenic contamination in Moira River and Moira Lake from historic gold mine operations is of increasing environmental concern to the local community. In this study, the current arsenic contamination status in water, sediment, and plants was investigated. Elevated levels of arsenic in the surface water of up to 75 ng mL{sup -1} in Moira River and 50 ng mL{sup -1} in Moira Lake were detected, 98% of which was present as arsenate. High concentrations of arsenic (>300 ng mL{sup -1}), mainly present as arsenite, were detected in sediment porewaters. A sediment profile of As from the West basin of Moira Lake showed lower As concentrations compared with data from the 1990s. An optimized extraction procedure using a phosphoric acid-ascorbic acid mixture demonstrated that an unknown ''As-complex'' which may consist of As, sulfide and organic matter is potentially responsible for the release of arsenite from the sediment to the overlying water column. Arsenic concentrations in plant samples ranged from 2.6 to 117 mg kg{sup -1}, dry weight. Accumulation of arsenic was observed in submerged plants collected from Moira River and Moira Lake. Only a small part of the arsenic (6.3-16.1%) in the plants was extractable with methanol-water (9:1), and most of this arsenic (70-93%) was inorganic arsenic. A variety of organic arsenic compounds, including simple methylated compounds (methylarsonic acid and dimethylarsinic acid), trimethylarsine oxide, and tetramethylarsonium cation were detected at trace levels. No arsenobetaine and arsenocholine was found in any plant sample. An unknown compound, most probably an arsenosugar was detected in the two submerged plants, coontail (Ceratophyllum demersum) and long-stemmed waterwort (Elatine triandra). These

This article draws on data collected during a 2-year project examining the deployment of a computerised decision support system. This computerised decision support system was designed to be used by non-clinical staff for dealing with calls to emergency (999) and urgent care (out-of-hours) services. One of the promises of computerised decisions support technologies is that they can 'hold' vast amounts of sophisticated clinical knowledge and combine it with decision algorithms to enable standardised decision-making by non-clinical (clerical) staff. This article draws on our ethnographic study of this computerised decision support system in use, and we use our analysis to question the 'automated' vision of decision-making in healthcare call-handling. We show that embodied and experiential (human) expertise remains central and highly salient in this work, and we propose that the deployment of the computerised decision support system creates something new, that this conjunction of computer and human creates a cyborg practice.

The computerisation of the procedures has been investigated for several years. Even though guidelines for such computerisation have been proposed, there is a need to extend and revise these guidelines. In this report, we look at what has been achieved so far, both within the Halden Project as well as within other organisations related to nuclear power plants. These experiences are often related to testing of particular computerised procedure systems either in research laboratories or in nuclear utilities. These activities have accumulated a body of general knowledge on the subject, as documented in other 'lessons learned' reports of the past. This report will extend this accepted body of knowledge. Furthermore, we identify the unresolved problems that need to be further studied to make usable computerised procedures for the future. The report identifies selected qualities that should be reinforced to make computerised procedure systems better. In particular, the integration aspect is emphasised. A flexible integration with the operator tasks and the remaining interfaces of the control room is important. Unless this integration is accomplished, the computerised procedures will not be functional. Another aspect of integration is combination with other systems inclusive those systems that deal with the plant documentation, electronic or paper based. This kind of integration is important to the safe and reliable operation of the plant. Good integration with plant documentation is instrumental in creating reliable QA of the procedures that covers the whole life cycle of the procedure. (Author). 48 refs., 12 figs., 2 tabs

The computerised Mayfair Accountancy System (MYDAS) has been developed to account for irradiated components in the Mayfair Laboratory at Culcheth and supersedes a card-index system. The computerised system greatly improves the availability of the data held and it ensures, by means of extensive data validation programs, that the data accurately represent the current inventory of irradiated components in the Laboratory. The system has been implemented on the Risley ICL 2966 main-frame computer and uses an IDMS database to store the data. The computer is accessed through the facilities of the Transaction Processing Management System (TPMS) providing rapid and secure access to the database from several visual display units and printers simultaneously.

Telemedicine is changing traditional nursing care, and entails nurses performing advanced and complex care within a new clinical environment, and monitoring patients at a distance. Telemedicine practice requires complex disease management, advocating that the nurses' reasoning and decision-making processes are supported. Computerised decision support systems are being used increasingly to assist reasoning and decision-making in different situations. However, little research has focused on the clinical reasoning of nurses using a computerised decision support system in a telemedicine setting. Therefore, the objective of the study is to explore the process of telemedicine nurses' clinical reasoning when using a computerised decision support system for the management of patients with chronic obstructive pulmonary disease. The factors influencing the reasoning and decision-making processes were investigated. In this ethnographic study, a combination of data collection methods, including participatory observations, the think-aloud technique, and a focus group interview was employed. Collected data were analysed using qualitative content analysis. When telemedicine nurses used a computerised decision support system for the management of patients with complex, unstable chronic obstructive pulmonary disease, two categories emerged: "the process of telemedicine nurses' reasoning to assess health change" and "the influence of the telemedicine setting on nurses' reasoning and decision-making processes". An overall theme, termed "advancing beyond the system", represented the connection between the reasoning processes and the telemedicine work and setting, where being familiar with the patient functioned as a foundation for the nurses' clinical reasoning process. In the telemedicine setting, when supported by a computerised decision support system, nurses' reasoning was enabled by the continuous flow of digital clinical data, regular video-mediated contact and shared decision

Sixteen patients suspected of having left ventricular mural thrombi were studied. All had suffered transmural myocardial infarction. Fifteen patients had a ventricular aneurysm. One had had systemic emboli. The mean length of time between the myocardial infarction and the study was 14.8 months, with a range of one month to 79 months. All patients underwent computerised tomography of the heart, M-mode echocardiography (M-mode), and two-dimensional echocardiography (2-D). Eight patients underwent left ventricular cineangiography. Five patients had surgical confirmation. Computerised tomography, two-dimensional, and M-mode echocardiography predicted left ventricular mural thrombi in 10, eight, and one of the 16 patients, respectively. Left ventricular cineangiography predicted left ventricular mural thrombi in four out of eight patients. Computerised tomography and left ventricular cineangiography correctly predicted the presence or absence of left ventricular thrombi in all five patients who underwent operation. In the same group, however, two-dimensional and M-mode echocardiography failed to predict the presence of thrombi in one and three patients, respectively. Among the 11 patients without surgical confirmation, one, in whom no left ventricular thrombi were shown by M-mode and two-dimensional echocardiography, was found to have thrombi on computerised tomography. In another, two-dimensional echocardiography was positive but this finding was not confirmed either by computerised tomography or by left ventricular angiography. (author)

Aragonès, Enric; Comín, Eva; Cavero, Myriam; Pérez, Víctor; Molina, Cristina; Palao, Diego

Despite its clinical relevance and its importance as a public health problem, there are major gaps in the management of depression. Evidence-based clinical guidelines are useful to improve processes and clinical outcomes. In order to make their implementation easier these guidelines have been transformed into computerised clinical decision support systems. In this article, a description is presented on the basics and characteristics of a new computerised clinical guideline for the management of major depression, developed in the public health system in Catalonia. This tool helps the clinician to establish reliable and accurate diagnoses of depression, to choose the best treatment a priori according to the disease and the patient characteristics. It also emphasises the importance of systematic monitoring to assess the clinical course, and to adjust therapeutic interventions to the patient's needs at all times.

Full Text Available A prototyping approach was used to determine the essential system requirements of a computerised patient record information system for a typical township primary health care clinic. A pilot clinic was identified and the existing manual system and business processes in this clinic was studied intensively before the first prototype was implemented. Interviews with users, incidental observations and analysis of actual data entered were used as primary techniques to refine the prototype system iteratively until a system with an acceptable data set and adequate functionalities were in place. Several non-functional and user-related requirements were also discovered during the prototyping period.

Computerising documentation

The nuclear power generation industry is faced with public concern and government pressures over safety, efficiency and risk. Operators throughout the industry are addressing these issues with the aid of a new technology - technical document management systems (TDMS). Used for strategic and tactical advantage, the systems enable users to scan, archive, retrieve, store, edit, distribute worldwide and manage the huge volume of documentation (paper drawings, CAD data and film-based information) generated in building, maintaining and ensuring safety in the UK's power plants. The power generation industry has recognized that the management and modification of operation critical information is vital to the safety and efficiency of its power plants. Regulatory pressure from the Nuclear Installations Inspectorate (NII) to operate within strict safety margins or lose Site Licences has prompted the need for accurate, up-to-data documentation. A document capture and management retrieval system provides a powerful cost-effective solution, giving rapid access to documentation in a tightly controlled environment. The computerisation of documents and plans is discussed in this article. (Author)

The ultrasound examination showed an epigastric mass, which was delineated as a filling defect in the stomach on barium studies. The computerised tomographic scan showed a gastric mass with pockets of air in it, without post-contrast enhancement. This case highlights the characteristic appearance on computerised tomography of a bezoar within the stomach, a feature that is not commonly described in medical literature.

Application of the migration models implemented in the decision system MOIRA-PLUS to assess the long term behaviour of 137Cs in water and fish of the Baltic Sea

Monte, Luigi

2014-01-01

This work presents and discusses the results of an application of the contaminant migration models implemented in the decision support system MOIRA-PLUS to simulate the time behaviour of the concentrations of 137 Cs of Chernobyl origin in water and fish of the Baltic Sea. The results of the models were compared with the extensive sets of highly reliable empirical data of radionuclide contamination available from international databases and covering a period of, approximately, twenty years. The model application involved three main phases: a) the customisation performed by using hydrological, morphometric and water circulation data obtained from the literature; b) a blind test of the model results, in the sense that the models made use of default values of the migration parameters to predict the dynamics of the contaminant in the environmental components; and c) the adjustment of the model parameter values to improve the agreement of the predictions with the empirical data. The results of the blind test showed that the models successfully predicted the empirical contamination values within the expected range of uncertainty of the predictions (confidence level at 68% of approximately a factor 2). The parameter adjustment can be helpful for the assessment of the fluxes of water circulating among the main sub-basins of the Baltic Sea, substantiating the usefulness of radionuclides to trace the movement of masses of water in seas. - Highlights: • The MOIRA-PLUS models were applied to 137 Cs in water and fish of Baltic Sea. • The model results were compared with empirical values from the HELCOM dataset. • Values of some model parameters were adjusted to improve the model performances. • The parameter adjustment helps to evaluate radionuclide fluxes through the Baltic

Saving time with a computerised handbook

The DE/CAASE computerised engineering handbook (Desktop Engineering, Mahwah, NJ, USA) is a software tool designed to automate a wide variety of engineering tasks that are typically performed with an engineering handbook and hand calculator. It significantly reduces the time taken to perform these tasks. For example, instead of spending 60 minutes on determining section properties of composite sections in control room panels and other equipment by hand, it might take less than 5 minutes by using the computerised handbook. Similarly, mode shapes and frequencies of simple structures may take less than 10 minutes to calculate, compared with the hours it used to take. (author)

1990-01-01

At the OECD Halden Reactor Project, the COPMA system has been developed in order to investigate whether procedures can be executed more safety and efficiently if they are computerised, i.e. if the operator uses a CRT-based system instead of written manuals. Procedures are entered in a procedure data base using PED, a procedure editor. Each procedure is given a textual as well as a graphical representation. For the textual representation, the language PROLA is used, a language which has been designed for simple procedure specification. The COPMA online system lets the operator execute procedures that are stored in the procedure data base. The operator interface is a screen divided into non-overlapping windows each serving a different purpose. All commands to the system are given by moving a mouse device around and clicking buttons on top of the mouse. A procedure consists of steps, each step containing a number of instructions. The operator works on one activity at a time, an activity to be seen as a procedure instance. A graph shows the overall procedure (or activity) structure in a window and activity execution is traced in the graph. Another windows shows the instructions of the step currently being executed. The operator steps through the activity by selecting whether and how to execute the listed instructions. COPMA can maintain the status of several activities in parallel, so that the operator can easily switch between different activities. COPMA is linked to a PWR nuclear simulator over Ethernet using the TCP/IP protocol. This gives a number of advantages as compared to conventional written procedures, especially the fact that COPMA can help collect data from the procedure data base automatically

Advances in microcomputer hardware and software technology have made computerised outpatient medical records practical. We have developed a programme based on the Summary Time-Oriented Record (STOR) system which complements existing paper-based record keeping. The elements of the Problem Oriented Medical Record (POMR) System are displayed in two windows within one screen, namely, the SOAP (Subjective information, Objective information, Assessments and Plans) elements in the Reason For Encounter (RFE) window and the problem list with outcomes in the Problem List (PL) window. Context sensitive child windows display details of plans of management in the RFE window and clinical notes in the PL window. The benefits of such innovations to clinical decision making and practice based research and its medico-legal implications are discussed.

To quantify and to evaluate the reliability of Primary Care (PC) computerised medication records of as an information source of patient chronic medications, and to identify associated factors with the presence of discrepancies. A descriptive cross-sectional study. General Referral Hospital in Murcia. Patients admitted to the cardiology-chest diseases unit, during the months of February to April 2013, on home treatment, who agreed to participate in the study. Evaluation of the reliability of Primary Care computerised medication records by analysing the concordance, by identifying discrepancies, between the active medication in these records and that recorded in pharmacist interview with the patient/caregiver. Identification of associated factors with the presence of discrepancies was analysed using a multivariate logistic regression. The study included a total of 308 patients with a mean of 70.9 years (13.0 SD). The concordance of active ingredients was 83.7%, and this decreased to 34.7% when taking the dosage into account. Discrepancies were found in 97.1% of patients. The most frequent discrepancy was omission of frequency (35.6%), commission (drug added unjustifiably) (14.6%), and drug omission (12.7%). Age older than 65 years (1.98 [1.08 to 3.64]), multiple chronic diseases (1.89 [1.04 to 3.42]), and have a narcotic or psychotropic drug prescribed (2.22 [1.16 to 4.24]), were the factors associated with the presence of discrepancies. Primary Care computerised medication records, although of undoubted interest, are not be reliable enough to be used as the sole source of information on patient chronic medications when admitted to hospital.

We outline the evolution of a computerised systematic observation tool and describe the process for establishing the validity and reliability of this new instrument. The Coach Analysis and Interventions System (CAIS) has 23 primary behaviours related to physical behaviour, feedback/reinforcement, instruction, verbal/non-verbal, questioning and management. The instrument also analyses secondary coach behaviour related to performance states, recipient, timing, content and questioning/silence. The CAIS is a multi-dimensional and multi-level mechanism able to provide detailed and contextualised data about specific coaching behaviours occurring in complex and nuanced coaching interventions and environments that can be applied to both practice sessions and competition.

Full Text Available Abstract Background The ideal method to encourage uptake of clinical guidelines in hospitals is not known. Several strategies have been suggested. This study evaluates the impact of academic detailing and a computerised decision support system (CDSS on clinicians' prescribing behaviour for patients with community acquired pneumonia (CAP. Methods The management of all patients presenting to the emergency department over three successive time periods was evaluated; the baseline, academic detailing and CDSS periods. The rate of empiric antibiotic prescribing that was concordant with recommendations was studied over time comparing pre and post periods and using an interrupted time series analysis. Results The odds ratio for concordant therapy in the academic detailing period, after adjustment for age, illness severity and suspicion of aspiration, compared with the baseline period was OR = 2.79 [1.88, 4.14], p Conclusion Deployment of a computerised decision support system was associated with an early improvement in antibiotic prescribing practices which was greater than the changes seen with academic detailing. The sustainability of this intervention requires further evaluation.

Full Text Available Background Ethnicity recording within primary care computerised medical record (CMR systems is suboptimal, exacerbated by tangled taxonomies within current coding systems. Objective To develop a method for extending ethnicity identification using routinely collected data. Methods We used an ontological method to maximise the reliability and prevalence of ethnicity information in the Royal College of General Practitioner’s Research and Surveillance database. Clinical codes were either directly mapped to ethnicity group or utilised as proxy markers (such as language spoken from which ethnicity could be inferred. We compared the performance of our method with the recording rates that would be identified by code lists utilised by the UK pay for the performance system, with the help of the Quality and Outcomes Framework (QOF. Results Data from 2,059,453 patients across 110 practices were included. The overall categorisable ethnicity using QOF codes was 36.26% (95% confidence interval (CI: 36.20%–36.33%. This rose to 48.57% (CI:48.50%–48.64% using the described ethnicity mapping process. Mapping increased across all ethnic groups. The largest increase was seen in the white ethnicity category (30.61%; CI: 30.55%–30.67% to 40.24%; CI: 40.17%–40.30%. The highest relative increase was in the ethnic group categorised as the other (0.04%; CI: 0.03%–0.04% to 0.92%; CI: 0.91%–0.93%. Conclusions This mapping method substantially increases the prevalence of known ethnicity in CMR data and may aid future epidemiological research based on routine data.

Cigarette smoking is often associated with the development of several respiratory diseases however, if diagnosed early, the changes in the lung tissue caused by smoking may be reversible. Computerised respiratory sounds have shown to be sensitive to detect changes within the lung tissue before any other measure, however it is unknown if it is able to detect changes in the lungs of healthy smokers. This study investigated the differences between computerised respiratory sounds of healthy smokers and non-smokers. Healthy smokers and non-smokers were recruited from a university campus. Respiratory sounds were recorded simultaneously at 6 chest locations (right and left anterior, lateral and posterior) using air-coupled electret microphones. Airflow (1.0-1.5 l/s) was recorded with a pneumotachograph. Breathing phases were detected using airflow signals and respiratory sounds with validated algorithms. Forty-four participants were enrolled: 18 smokers (mean age 26.2, SD = 7 years; mean FEV 1 % predicted 104.7, SD = 9) and 26 non-smokers (mean age 25.9, SD = 3.7 years; mean FEV 1 % predicted 96.8, SD = 20.2). Smokers presented significantly higher frequency at maximum sound intensity during inspiration [(M = 117, SD = 16.2 Hz vs. M = 106.4, SD = 21.6 Hz; t(43) = -2.62, p = 0.0081, d z  = 0.55)], lower expiratory sound intensities (maximum intensity: [(M = 48.2, SD = 3.8 dB vs. M = 50.9, SD = 3.2 dB; t(43) = 2.68, p = 0.001, d z  = -0.78)]; mean intensity: [(M = 31.2, SD = 3.6 dB vs. M = 33.7,SD = 3 dB; t(43) = 2.42, p = 0.001, d z  = 0.75)] and higher number of inspiratory crackles (median [interquartile range] 2.2 [1.7-3.7] vs. 1.5 [1.2-2.2], p = 0.081, U = 110, r = -0.41) than non-smokers. Significant differences between computerised respiratory sounds of smokers and non-smokers have been found. Changes in respiratory sounds are often the earliest sign of disease. Thus, computerised respiratory sounds

2016-02-01

Despite the widespread use of cardiotocography in foetal monitoring, the evaluation of foetal status suffers from a considerable inter and intra-observer variability. In order to overcome the main limitations of visual cardiotocographic assessment, computerised methods to analyse cardiotocographic recordings have been recently developed. In this study, a new software for automated analysis of foetal heart rate is presented. It allows an automatic procedure for measuring the most relevant parameters derivable from cardiotocographic traces. Simulated and real cardiotocographic traces were analysed to test software reliability. In artificial traces, we simulated a set number of events (accelerations, decelerations and contractions) to be recognised. In the case of real signals, instead, results of the computerised analysis were compared with the visual assessment performed by 18 expert clinicians and three performance indexes were computed to gain information about performances of the proposed software. The software showed preliminary performance we judged satisfactory in that the results matched completely the requirements, as proved by tests on artificial signals in which all simulated events were detected from the software. Performance indexes computed in comparison with obstetricians' evaluations are, on the contrary, not so satisfactory; in fact they led to obtain the following values of the statistical parameters: sensitivity equal to 93%, positive predictive value equal to 82% and accuracy equal to 77%. Very probably this arises from the high variability of trace annotation carried out by clinicians. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The SMile Card was developed as a means for computerising clinical information for the purpose of transferability, accessibility, standardisation and compilation of a national database of demographic and clinical information about multiple sclerosis (MS) patients. In many European countries, centres for MS are organised independently from one another making collaboration, consultation and patient referral complicated. Only the more highly advanced clinical centres, generally located in large urban areas, have had the possibility to utilise technical possibilities for improving the organisation of patient clinical and research information, although independently from other centres. The information system, developed utilising the Visual Basic language for Microsoft Windows 95, stores information via a 'smart card' in a database which is initiated and updated utilising a microprocessor, located at each neurological clinic. The SMile Card, currently being tested in Italy, permits patients to carry with them all relevant medical information without limitations. Neurologists are able to access and update, via the microprocessor, the patient's entire medical history and MS-related information, including the complete neurological examination and laboratory test results. The SMile Card provides MS patients and neurologists with a complete computerised archive of clinical information which is accessible throughout the country. In addition, data from the SMile Card system can be exported to other database programs.

Clinical and cost-effectiveness of computerised cognitive behavioural therapy for depression in primary care: Design of a randomised trial

Full Text Available Abstract Background Major depression is a common mental health problem in the general population, associated with a substantial impact on quality of life and societal costs. However, many depressed patients in primary care do not receive the care they need. Reason for this is that pharmacotherapy is only effective in severely depressed patients and psychological treatments in primary care are scarce and costly. A more feasible treatment in primary care might be computerised cognitive behavioural therapy. This can be a self-help computer program based on the principles of cognitive behavioural therapy. Although previous studies suggest that computerised cognitive behavioural therapy is effective, more research is necessary. Therefore, the objective of the current study is to evaluate the (cost- effectiveness of online computerised cognitive behavioural therapy for depression in primary care. Methods/Design In a randomised trial we will compare (a computerised cognitive behavioural therapy with (b treatment as usual by a GP, and (c computerised cognitive behavioural therapy in combination with usual GP care. Three hundred mild to moderately depressed patients (aged 18–65 will be recruited in the general population by means of a large-scale Internet-based screening (N = 200,000. Patients will be randomly allocated to one of the three treatment groups. Primary outcome measure of the clinical evaluation is the severity of depression. Other outcomes include psychological distress, social functioning, and dysfunctional beliefs. The economic evaluation will be performed from a societal perspective, in which all costs will be related to clinical effectiveness and health-related quality of life. All outcome assessments will take place on the Internet at baseline, two, three, six, nine, and twelve months. Costs are measured on a monthly basis. A time horizon of one year will be used without long-term extrapolation of either costs or quality of life

Chow, Angela L. P.; Lye, David C.; Arah, Onyebuchi A.

2015-11-01

Antibiotic computerised decision support systems (CDSSs) are shown to improve antibiotic prescribing, but evidence of beneficial patient outcomes is limited. We conducted a prospective cohort study in a 1500-bed tertiary-care hospital in Singapore, to evaluate the effectiveness of the hospital’s antibiotic CDSS on patients’ clinical outcomes, and the modification of these effects by patient factors. To account for clustering, we used multilevel logistic regression models. One-quarter of 1886 eligible inpatients received CDSS-recommended antibiotics. Receipt of antibiotics according to CDSS’s recommendations seemed to halve mortality risk of patients (OR 0.54, 95% CI 0.26-1.10, P = 0.09). Patients aged ≤65 years had greater mortality benefit (OR 0.45, 95% CI 0.20-1.00, P = 0.05) than patients that were older than 65 (OR 1.28, 95% CI 0.91-1.82, P = 0.16). No effect was observed on incidence of Clostridium difficile (OR 1.02, 95% CI 0.34-3.01), and multidrug-resistant organism (OR 1.06, 95% CI 0.42-2.71) infections. No increase in infection-related readmission (OR 1.16, 95% CI 0.48-2.79) was found in survivors. Receipt of CDSS-recommended antibiotics reduced mortality risk in patients aged 65 years or younger and did not increase the risk in older patients. Physicians should be informed of the benefits to increase their acceptance of CDSS recommendations.

Integrating the Radiology Information System with Computerised Provider Order Entry: The Impact on Repeat Medical Imaging Investigations.

2016-01-01

Repeat and redundant procedures in medical imaging are associated with increases in resource utilisation and labour costs. Unnecessary medical imaging in some modalities, such as X-Ray (XR) and Computed Tomography (CT) is an important safety issue because it exposes patients to ionising radiation which can be carcinogenic and is associated with higher rates of cancer. The aim of this study was to assess the impact of implementing an integrated Computerised Provider Order Entry (CPOE)/Radiology Information System (RIS)/Picture Archiving and Communications System (PACS) system on the number of XR and CT imaging procedures (including repeat imaging requests) for inpatients at a large metropolitan hospital. The study found that patients had an average 0.47 fewer XR procedures and 0.07 fewer CT procedures after the implementation of the integrated system. Part of this reduction was driven by a lower rate of repeat procedures: the average inpatient had 0.13 fewer repeat XR procedures within 24-hours of the previous identical XR procedure. A similar decrease was not evident for repeat CT procedures. Reduced utilisation of imaging procedures (especially those within very short intervals from the previous identical procedure, which are more likely to be redundant) has implications for the safety of patients and the cost of medical imaging services.

Depression in adolescents is a common and impairing problem. Effective psychological therapies for depression are not accessed by most adolescents. Computerised therapy offers huge potential for improving access to treatment. To test the efficacy of Stressbusters, a Computerised-CBT (C-CBT) programme for depression in young people. Multi-site, schools-based, RCT of C-CBT compared to Waiting List, for young people (N = 112; aged 12-16) with significant symptoms of depression, using multiple-informants (adolescents, parents, teachers), with follow-up at 3 and 6 months. Relative to being on a Waiting List, C-CBT was associated with statistically significant and clinically meaningful improvements in symptoms of depression and anxiety according to adolescent self-report; and with a trend towards improvements in depression and anxiety according to parent-report. Improvements were maintained at follow-up. Treatment gains were similar for boys and girls across the participating age range. Treatment effect was partially mediated by changes in ruminative thinking. Teachers rated adolescents as having few emotional or behavioural problems, both before and after intervention. C-CBT had no detectable effect on academic attainment. In the month after intervention, young people who received C-CBT had significantly fewer absences from school than those on the Waiting List. C-CBT shows considerable promise for the treatment of mild-moderate depression in adolescents. Copyright © 2015 Elsevier Ltd. All rights reserved.

One of the proposals for improving clinical practice is to introduce computerised decision support systems (CDSS) and integrate these with electronic medical records. Accordingly, this study sought to systematically review evidence on the effectiveness of CDSS in the management of depression. A search was performed in Medline, EMBASE and PsycInfo, in order to do this. The quality of quantitative studies was assessed using the SIGN method, and qualitative studies using the CASPe checklist. Seven studies were identified (3 randomised clinical trials, 3 non-randomised trials, and one qualitative study). The CDSS assessed incorporated content drawn from guidelines and other evidence-based products. In general, the CDSS had a positive impact on different aspects, such as the screening and diagnosis, treatment, improvement in depressive symptoms and quality of life, and referral of patients. The use of CDSS could thus serve to optimise care of depression in various scenarios by providing recommendations based on the best evidence available and facilitating decision-making in clinical practice.

Computerised analysis of facial emotion expression in eating disorders

Science.gov (United States)

2017-01-01

Background Problems with social-emotional processing are known to be an important contributor to the development and maintenance of eating disorders (EDs). Diminished facial communication of emotion has been frequently reported in individuals with anorexia nervosa (AN). Less is known about facial expressivity in bulimia nervosa (BN) and in people who have recovered from AN (RecAN). This study aimed to pilot the use of computerised facial expression analysis software to investigate emotion expression across the ED spectrum and recovery in a large sample of participants. Method 297 participants with AN, BN, RecAN, and healthy controls were recruited. Participants watched film clips designed to elicit happy or sad emotions, and facial expressions were then analysed using FaceReader. Results The finding mirrored those from previous work showing that healthy control and RecAN participants expressed significantly more positive emotions during the positive clip compared to the AN group. There were no differences in emotion expression during the sad film clip. Discussion These findings support the use of computerised methods to analyse emotion expression in EDs. The findings also demonstrate that reduced positive emotion expression is likely to be associated with the acute stage of AN illness, with individuals with BN showing an intermediate profile.

Cognitive rehabilitation for mild cognitive impairment (MCI) and early Alzheimer's disease is readily available to the geriatric population. Initial evidence suggests that techniques incorporating motivational strategies to enhance treatment engagement may provide more benefit than computerised training alone. Seventy four adults with subclinical cognitive decline were randomly assigned to computerised cognitive training (CCT), Cognitive Vitality Training (CVT), or an Active Control Group (ACG), and underwent neuropsychological evaluations at baseline and four-month follow-up. Significant differences were found in changes in performance on the Modified Mini Mental State Examination (mMMSE) and measures of verbal learning and memory across treatment groups. Experimental groups showed greater preservation of functioning on the mMMSE than the ACG group, the CVT group performed better than the ACG group on one measure of verbal learning and both measures of verbal memory, and the CCT group performed better than the ACG group on one measure of verbal learning and one measure of verbal memory. There were no significant group differences between the CVT and CCT groups on measures of verbal learning or memory. It was concluded that computerised cognitive training may offer the most benefit when incorporated into a therapeutic milieu rather than administered alone, although both appear superior to more generic forms of cognitive stimulation.

The computerised and remote operated sludge lancing equipment (SLE) uses high velocity narrow water jets for dislodging and removal of hard and strongly adhesive sludge from the secondary side tube sheet of mushroom type steam generators of Indian PHWRs. During the years of plant operation, corrosion products and other solids deposit in the form of sludge on the tube sheet of steam generators. The sludge formation not only affects adversely the steam generator performance but also diminishes its service life if left unchecked

One quarter of children and young people (CYP) experience anxiety and/or depression before adulthood, but treatment is sometimes unavailable or inadequate. Self-help interventions may have a role in augmenting treatment and this work aimed to systematically review the evidence for computerised anxiety and depression interventions in CYP aged 5-25 years old. Databases were searched for randomised controlled trials and 27 studies were identified. For young people (12-25 years) with risk of diagnosed anxiety disorders or depression, computerised CBT (cCBT) had positive effects for symptoms of anxiety (SMD -0.77, 95% CI -1.45 to -0.09, k = 6, N = 220) and depression (SMD -0.62, 95% CI -1.13 to -0.11, k = 7, N = 279). In a general population study of young people, there were small positive effects for anxiety (SMD -0.15, 95% CI -0.26 to -0.03; N = 1273) and depression (SMD -0.15, 95% CI -0.26 to -0.03; N = 1280). There was uncertainty around the effectiveness of cCBT in children (5-11 years). Evidence for other computerised interventions was sparse and inconclusive. Computerised CBT has potential for treating and preventing anxiety and depression in clinical and general populations of young people. Further program development and research is required to extend its use and establish its benefit in children. Copyright © 2015 Elsevier Ltd. All rights reserved.

Serious educational games (SEG) have been shown to be effective in educating young people about a range of topics, including languages and maths. This paper identifies the use of computerised SEGs in education about alcohol and other drugs and reviews their impact on the prevention of alcohol and drug use. The Cochrane Library, EMBASE, MEDLINE, ERIC, Scopus, psychINFO, pubMED and DRUG databases were searched in February 2013. Additional publications were obtained from the reference lists of the relevant papers. Studies were included if they described an evaluation of a computerised SEG that targeted alcohol and/or other drugs and had been trialled with adolescents. Eight SEGs were identified targeting tobacco, alcohol, cannabis, methamphetamine, ecstasy, inhalants, cocaine and opioids. Six reported positive outcomes in terms of increased content knowledge and two reported increased negative attitudes towards the targeted drugs. Only one reported a decrease in the frequency of drug use. This is the first review of the efficacy of computerised SEGs for alcohol and other drugs for adolescents. Results suggest that SEGs can increase content knowledge of alcohol and other drugs. Evidence concerning impacts on negative attitudes and alcohol and drug use is limited, with few studies examining these outcomes. © 2013 Australasian Professional Society on Alcohol and other Drugs.

The Inforare project aims to set up a system for the sharing of clinical and familial data, in order to study how genes are related to the severity of sickle cell disease. While the computerisation of clinical records represents a valuable research goal, an ethical framework is necessary to guarantee patients' protection and their rights in this developing field. Issues relating to patient information during the Inforare study were analysed by the steering committee. Several major concerns were discussed by the committee and formalized in the patients' information letter: educating patients to aid the recruitment of family members, rules of confidentiality and the disclosure of aggregate, individual and unexpected research results. This paper presents the main issues addressed.

Full Text Available At universities, educating students on real-life practices is one of the key drivers in a changing academic environment. Academic institutions encourage the study of the learning environment and ensure that appropriate strategies are in place for educating students. A first-year Accounting I student stated the importance of computerised accounting: ‘Computerised accounting is used in the workplace and therefore using it in varsity, grants students a view on how things will be after completion of their respective degrees.’ Accordingly, the purpose of this study was to empirically investigate the perceived acquisition of information technology (IT knowledge and determine the skills required for students to convert the knowledge gained into actions as a learning curve for accounting students entering the business world. The results indicated that students’ knowledge of Accounting I increased with the integration of computerised Accounting in the Accounting I Curriculum.

Physical inspection and certification of nuclear reactor fuel element components is an activity demanding utmost imagination and skill in devising accurate measuring systems. There is also need for remote handling, automation, rapid processing and inspection data print out when dealing with reactor fuel material. This report deals with an automatic computerised fuel pellet inspection system that has been developed in Radiometallurgy Division, B.A.R.C. to carry out dimensional and weight measurements on fuel pellets for the Fast Breeder Test Reactor (FBTR) at Kalpakkam near Madras. The system consists of several subsystems each developed especially for a specific purpose and as such items are not available off the shelf from manufacturers in India. If a general approach is adopted towards the report, there are many innovations and ideas that can be used in the automatic inspection of a variety of products in industry. As the system is fairly involved the report does not attempt to deal with detailed description of the equipment. The function of the system is to accept a certain quantity of fuel pellets in a bowl feeder, separate the pellets rejected owing to their exceeding dimensional and weight limits and form columns of accepted pellets. Dimensional and weight limits can be set as required and all inspection data are presented in a printed format. The system processes pellets at the rate of 15 per minute. The entire system can be run by operators with no special skills. The unit is currently in use for the inspection of mixed carbide fuel pellets for FBTR. (author)

New strategies need to be developed for the early recognition and rapid response for the management of sepsis. To achieve this purpose, the Multidisciplinary Sepsis Team (MST) developed the Computerised Sepsis Protocol Management (PIMIS). The aim of this study was to evaluate the convenience of using PIMIS, as well as the activity of the MST. An analysis was performed on the data collected from solicited MST consultations (direct activation of PIMIS by attending physician or telephone request) and unsolicited ones (by referral from the microbiology laboratory or an automatic referral via the hospital vital signs recording software [SIDCV]), as well as the hospital department, source of infection, treatment recommendation, and acceptance of this. Of the 1,581 first consultations, 65.1% were solicited consultations (84.1% activation of PIMIS and 15.9% by telephone). The majority of unsolicited consultations were generated by the microbiology laboratory (95.2%), and 4.8% from the SIDCV. Referral from solicited consultations were generated sooner (5.63days vs 8.47days; P<.001) and came from clinical specialties rather than from the surgical ward (73.0% vs 39.1%; P<.001). A recommendation was made for antimicrobial prescription change in 32% of first consultations. The treating physician accepted 78.1% of recommendations. The high rate of solicited consultations and acceptance of recommended prescription changes suggest that a MST is seen as a helpful resource, and that PIMIS software is perceived to be useful and convenient to use, as it is the main source of referral.

A challenge in treatment research is the necessity of adhering to protocol and regulatory strictures while maintaining flexibility to meet patients' treatment needs and to accommodate variations among protocols. Another challenge is the acquisition of large amounts of data in an occasionally hectic environment, along with the provision of seamless methods for exporting, mining and querying the data. We have automated several major functions of our outpatient treatment research clinic for studies in drug abuse and dependence. Here we describe three such specialised applications: the Automated Contingency Management (ACM) system for the delivery of behavioural interventions, the transactional electronic diary (TED) system for the management of behavioural assessments and the Protocol Workflow System (PWS) for computerised workflow automation and guidance of each participant's daily clinic activities. These modules are integrated into our larger information system to enable data sharing in real time among authorised staff. ACM and the TED have each permitted us to conduct research that was not previously possible. In addition, the time to data analysis at the end of each study is substantially shorter. With the implementation of the PWS, we have been able to manage a research clinic with an 80 patient capacity, having an annual average of 18,000 patient visits and 7300 urine collections with a research staff of five. Finally, automated data management has considerably enhanced our ability to monitor and summarise participant safety data for research oversight. When developed in consultation with end users, automation in treatment research clinics can enable more efficient operations, better communication among staff and expansions in research methods.

Micro-computerised tomography optimisation for the measurement of bone mineral density around titanium dental implants

International Nuclear Information System (INIS)

Park, C.; Swain, M.; Duncan, W.

2010-01-01

Titanium dental implants (screws) are commonly used to replace missing teeth by forming a biological union with bone ('osseointegration'). Micro-computerised tomography (μCT) may be useful for measuring bone mineral density around dental implants. Major issues arise because of various artefacts that occur with polychromatic X-rays associated bench type instruments that may compromise interpretation of the observations. In this study various approaches to minimise artefacts such as; beam hardening, filtering and edge effects are explored with a homogeneous polymeric material, Teflon, with and without an implant present. The implications of the limitations of using such polychromatic μCT systems to quantify bone mineral density adjacent to the implant are discussed. (author)

E-mental health and m-mental health include the use of technology in the prevention, treatment and aftercare of mental health problems. With the economical pressure on mental health services increasing, e-mental health and m-mental health could bridge treatment gaps, reduce waiting times for patients and deliver interventions at lower costs. However, despite the existence of numerous effective interventions, the transition of computerised interventions into care is slow. The aim of the present study was to investigate the acceptability of e-mental health and m-mental health in the general population. An advisory group of service users identified dimensions that potentially influence an individual's decision to engage with a particular treatment for mental health problems. A large sample (N = 490) recruited through email, flyers and social media was asked to rate the acceptability of different treatment options for mental health problems on these domains. Results were analysed using repeated measures MANOVA. Participants rated the perceived helpfulness of an intervention, the ability to motivate users, intervention credibility, and immediate access without waiting time as most important dimensions with regard to engaging with a treatment for mental health problems. Participants expected face-to-face therapy to meet their needs on most of these dimensions. Computerised treatments and smartphone applications for mental health were reported to not meet participants' expectations on most domains. However, these interventions scored higher than face-to-face treatments on domains associated with the convenience of access. Overall, participants reported a very low likelihood of using computerised treatments for mental health in the future. Individuals in this study expressed negative views about computerised self-help intervention and low likelihood of use in the future. To improve the implementation and uptake, policy makers need to improve the public perception of such

The Pietermaritzburg Metropolitan Trauma Service formerly lacked a robust computerised trauma registry. This made surgical audit difficult for the purpose of quality of care improvement and development. We aimed to design, construct and implement a computerised trauma registry within our service. Twelve months following its implementation, we sought to examine and report on the quality of the registry. Formal ethical approval to maintain a computerised trauma registry was obtained prior to undertaking any design and development. Appropriate commercial software was sourced to develop this project. The registry was designed as a flat file. A flat file is a plain text or mixed text and binary file which usually contains one record per line or physical record. Thereafter the registry file was launched onto a secure server. This provided the benefits of access security and automated backups. Registry training was provided to clients by the developer. The exercise of data capture was then integrated into the process of service delivery, taking place at the endpoint of patient care (discharge, transfer or death). Twelve months following its implementation, the compliance rates of data entry were measured. The developer of this project managed to design, construct and implement an electronic trauma registry into the service. Twelve months following its implementation the data were extracted and audited to assess the quality. A total of 2640 patient entries were captured onto the registry. Compliance rates were in the order of eighty percent and client satisfaction rates were high. A number of deficits were identified. These included the omission of weekend discharges and underreporting of deaths. The construction and implementation of the computerised trauma registry was the beginning of an endeavour to continue improvements in the quality of care within our service. The registry provided a reliable audit at twelve months post implementation. Deficits and limitations were

Minimally disruptive medicine is needed for patients with multimorbidity: time to develop computerised medical record systems to meet this requirement

Full Text Available Background Minimally disruptive medicine (MDM is proposed as a method for more appropriately managing people with multiple chronic disease. Much clinical management is currently single disease focussed, with people with multimorbidity being managed according to multiple single disease guidelines. Current initiatives to improve care include education about individual conditions and creating an environment where multiple guidelines might be simultaneously supported. The patientcentred medical home (PCMH is an example of the latter. However, educational programmes and PCMH may increase the burden on patients.Problem The cumulative workload for patients in managing the impact of multiple disease-specific guidelines is only relatively recently recognised. There is an intellectual vacuum as to how best to manage multimorbidity and how informatics might support implementing MDM. There is currently no alternative to multiple singlecondition- specific guidelines and a lack of certainty, should the treatment burden need to be reduced, as to which guideline might be ‘dropped’.Action The best information about multimorbidity is recorded in primary care computerised medical record (CMR systems and in an increasing number of integrated care organisations. CMR systems have the potential to flag individuals who might be in greatest need. However, CMR systems may also provide insights into whether there are ameliorating factors that might make it easier for them to be resilient to the burden of care. Data from such CMR systems might be used to develop the evidence base about how to better manage multimorbidity.Conclusions There is potential for these information systems to help reduce the management burden on patients and clinicians. However, substantial investment in research-driven CMR development is needed if we are to achieve this.

Audit and Feedback (A&F) is a widely used quality improvement technique that measures clinicians' clinical performance and reports it back to them. Computerised A&F (e-A&F) system interfaces may consist of four key components: (1) Summaries of clinical performance; (2) Patient lists; (3) Patient-level data; (4) Recommended actions. There is a lack of evidence regarding how to best design e-A&F interfaces; establishing such evidence is key to maximising usability, and in turn improving patient safety. To evaluate the usability of a novel theoretically-informed and research-led e-A&F system for primary care (the Performance Improvement plaN GeneratoR: PINGR). (1) Describe PINGR's design, rationale and theoretical basis; (2) Identify usability issues with PINGR; (3) Understand how these issues may interfere with the cognitive goals of end-users; (4) Translate the issues into recommendations for the user-centred design of e-A&F systems. Eight experienced health system evaluators performed a usability inspection using an innovative hybrid approach consisting of five stages: (1) Development of representative user tasks, Goals, and Actions; (2) Combining Heuristic Evaluation and Cognitive Walkthrough methods into a single protocol to identify usability issues; (3) Consolidation of issues; (4) Severity rating of consolidated issues; (5) Analysis of issues according to usability heuristics, interface components, and Goal-Action structure. A final list of 47 issues were categorised into 8 heuristic themes. The most error-prone heuristics were 'Consistency and standards' (13 usability issues; 28% of the total) and 'Match between system and real world' (n=10, 21%). The recommended actions component of the PINGR interface had the most usability issues (n=21, 45%), followed by patient-level data (n=5, 11%), patient lists (n=4, 9%), and summaries of clinical performance (n=4, 9%). The most error-prone Actions across all user Goals were: (1) Patient selection from a list; (2) Data

A computerised information system for the processing of borehole data with regard to uranium sources in the Republic of South Africa

1981-01-01

The various mining companies in the Republic of South Africa are under legal obligation to supply data concerning uranium resources to the Atomic Energy Board. As the process of manually summarising data and retrieving information for a great number of boreholes is a time-consuming and tedious task, a computerised system was needed to supply this information in a meaningful manner. Following a thorough systems analysis, a database information system was designed. Application programs were developed for the input, processing and tabulation of the data. This report describes the data-base organisation, consisting of a network of master and transaction files. A master file contains one or more keys which are used to input data into or extract data from a transaction file. Master and transaction files are normally linked by means of a linkpath, but in this application it was necessary to define some master files as unlinked units. The input into the database consists of administrative, stratigraphic and lithological data as well as data of gold, uranium, silver, thorium, platinum, sulphur and molybdenum mineralisation. Five types of data cards were developed to record the abovementioned information. Examples of the various data cards are contained in the report. On retrieving data the user of this system has several options regarding the sequence in which information is retrieved and the contents of the tables. The procedure to be used and the various options ar summarised in detail. The appendices summarise the utility programs, supporting job-control language and code lists. The program was written in PL/1 and the database is the TOTAL DATA BASE MANAGEMENT SYSTEM - RELEASE 8,0 from CINCOM SYSTEMS, INC [af

2015-10-23

Chronic obstructive pulmonary disease (COPD) is one of the commonest causes of death in the world and poses a substantial burden on healthcare systems and patients' quality of life. The largest component of the related healthcare costs is attributable to admissions due to acute exacerbation (AECOPD). The evidence that might support the effectiveness of the telemonitoring interventions in COPD is limited partially due to the lack of useful predictors for the early detection of AECOPD. Electronic stethoscopes and computerised analyses of respiratory sounds (CARS) techniques provide an opportunity for substantial improvement in the management of respiratory diseases. This exploratory study aimed to evaluate the feasibility of using: (a) a respiratory sensor embedded in a self-tailored housing for ageing users; (b) a telehealth framework; (c) CARS and (d) machine learning techniques for the remote early detection of the AECOPD. In a 6-month pilot study, 16 patients with COPD were equipped with a home base-station and a sensor to daily record their respiratory sounds. Principal component analysis (PCA) and a support vector machine (SVM) classifier was designed to predict AECOPD. 75.8% exacerbations were early detected with an average of 5 ± 1.9 days in advance at medical attention. The proposed method could provide support to patients, physicians and healthcare systems.

Devising new methods to improve neurocognitive impairment through cognitive remediation is an important research goal. We developed an original computer programme termed the Japanese Cognitive Rehabilitation Programme for Schizophrenia (JCORES) that provides cognitive practice across a broad range of abilities. The current study examined for the first time whether a cognitive remediation programme, including both computerised cognitive training using JCORES and group intervention such as enhancing meta-cognition and teaching strategies, is more effective than treatment as usual for improving neurocognitive and social functioning. Sixty-two outpatients with schizophrenia were randomised to either a cognitive remediation group or a control group. Participants engaged in two computerised cognitive training sessions and one group meeting per week for 12 weeks. The average number of total sessions attended (computerised cognitive practice + group intervention) was 32.3 (89.7%). The cognitive remediation group showed significantly more improvements in verbal memory, composite score of the Brief Assessment of Cognition in Schizophrenia, Japanese version (BACS-J), and general psychopathology on the Positive and Negative Syndrome Scale (PANSS) than the control group. These findings demonstrate that a cognitive remediation programme is feasible in Japan and is a more effective way to improve neurocognitive functioning and psychiatric symptoms.

Ntim-Amponsah, C T

1997-01-01

The Topcon Computerised Tonometer CT-20, a non-contact tonometer (NCT), was used to measure intraocular pressure (IOP) in mmHg in 1,226 subjects above the age of 30 years with no ocular pathology. The mean IOP was 14.41 mmHg and the standard deviation 3.43. The mean IOP far was higher in female (14.60) than male (14.22). This gender difference in the mean IOP was significant; t stat = 2.69, P < 0.5. Right IOP exceeded left IOP and this was highly significant in both male (t stat 4.03) and female (t stat 5.64) p < 0.01. This IOP asymmetry approximates a normal distribution. The mean of the differences (right-left IOP) and standard deviation for all subjects were 0.57 and 2.26 respectively. The range for the differences was- 10 to 10 mmHg. Asymmetry was greater in females than males (t stat = 2.05, p < 0.05). Knowledge of these statistics will help in decisions concerning glaucoma screening with NCT.

Full Text Available Abstract Background Currently ambulatory patients break one in four tablets before ingestion. Roughly 10% of them are not suitable for splitting because they lack score lines or because enteric or modified release coating is destroyed impairing safety and effectiveness of the medication. We assessed impact and safety of computerised decision support on the inappropriate prescription of split tablets. Methods We performed a prospective intervention study in a 1680-bed university hospital. Over a 15-week period we evaluated all electronically composed medication regimens and determined the fraction of tablets and capsules that demanded inappropriate splitting. In a subsequent intervention phase of 15 weeks duration for 10553 oral drugs divisibility characteristics were indicated in the system. In addition, an alert was generated and displayed during the prescription process whenever the entered dosage regimen demanded inappropriate splitting (splitting of capsules, unscored tablets, or scored tablets unsuitable for the intended fragmentation. Results During the baseline period 12.5% of all drugs required splitting and 2.7% of all drugs (257/9545 required inappropriate splitting. During the intervention period the frequency of inappropriate splitting was significantly reduced (1.4% of all drugs (146/10486; p = 0.0008. In response to half of the alerts (69/136 physicians adjusted the medication regimen. In the other half (67/136 no corrections were made although a switch to more suitable drugs (scored tablets, tablets with lower strength, liquid formulation was possible in 82% (55/67. Conclusion This study revealed that computerised decision support can immediately reduce the frequency of inappropriate splitting without introducing new safety hazards.

Computerised clinical decision support systems to improve medication safety in long-term care homes: a systematic review.

Computerised clinical decision support systems (CCDSS) are used to improve the quality of care in various healthcare settings. This systematic review evaluated the impact of CCDSS on improving medication safety in long-term care homes (LTC). Medication safety in older populations is an important health concern as inappropriate medication use can elevate the risk of potentially severe outcomes (ie, adverse drug reactions, ADR). With an increasing ageing population, greater use of LTC by the growing ageing population and increasing number of medication-related health issues in LTC, strategies to improve medication safety are essential. Databases searched included MEDLINE, EMBASE, Scopus and Cochrane Library. Three groups of keywords were combined: those relating to LTC, medication safety and CCDSS. One reviewer undertook screening and quality assessment. Overall findings suggest that CCDSS in LTC improved the quality of prescribing decisions (ie, appropriate medication orders), detected ADR, triggered warning messages (ie, related to central nervous system side effects, drug-associated constipation, renal insufficiency) and reduced injury risk among older adults. CCDSS have received little attention in LTC, as attested by the limited published literature. With an increasing ageing population, greater use of LTC by the ageing population and increased workload for health professionals, merely relying on physicians' judgement on medication safety would not be sufficient. CCDSS to improve medication safety and enhance the quality of prescribing decisions are essential. Analysis of review findings indicates that CCDSS are beneficial, effective and have potential to improve medication safety in LTC; however, the use of CCDSS in LTC is scarce. Careful assessment on the impact of CCDSS on medication safety and further modifications to existing CCDSS are recommended for wider acceptance. Due to scant evidence in the current literature, further research on implementation and

The diagnostic ranking and importance of computerised tomography was examined in 116 with abnormal findings in the mediastinal region, and was compared with conventional, non-invasive X-ray examinations. This method also yielded significant CT-specific additional information in the anterior mediastinum in 74.4% of the cases, in the mesomediastinum in 69.1%, in the posterior mediastinum in 79.2% in the upper thoracic aperture in 94.4% and in the paracardial region in 100% of the cases. The hilar region is an exception; in 68.8% of the cases, both methods were rated equal, whereas in 28.1% of the cases assessment via the CT method was even inferior. The specific additional information furnshed by the CT method justifies a wider application of CT in solving the following problems concerning the mediastinum: Clarification of a suspected but not yet established space-occupying growth in the mediastinum, before using invasive diagnostic methods such as mediastinoscopy and angiography; staging of an already identified primary mediastinal tumor or malignant lymphoma; in case of suspected changes in the large mediastinal vessels before employing angiography; on-target in the following diseases: bronchogenic carcinoma (because of improved pretherapeutic staging according to the TNM system), myasthenia gravis and identification of thymoma, hyperparathyroidism with suspected dystopic parathyroid glands.

Reducing avoidable nursing student attrition is an international challenge. A pattern of falling attendance is recognised as a frequent precursor to withdrawal from nursing programmes. To address concerns regarding nursing student attrition, the Scottish Government implemented a pilot project for a centralised Computerised Absence Management and Monitoring System (CAMMS). The CAMMS adopted an 'assertive outreach' approach, contacting students every two weeks via colour coded letters to tell them whether their attendance was 'excellent', 'good, but potentially causing concern'; or 'warning; attendance concerns/contact academic staff for support'. This article reports key findings from an evaluation of CAMMS. To explore the perceived impact of CAMMS on student support and attrition, from the perspectives of academic and administrative staff and students. Mixed methods evaluation design. Three large geographically dispersed Schools of Nursing in Scotland. 83 students; 20 academic staff; and 3 lead administrators. On-line cohort survey of academic staff and students; structured interviews with lead administrators. Findings reflected a spectrum of negative and positive views of CAMMS. Students who are attending regularly seem pleased that their commitment is recognised. Lecturers who teach larger groups report greater difficulty getting to know students individually and acknowledge the benefit of identifying potential attendance concerns at an early stage. Conversely, some students who received a 'warning' letter were frequently annoyed or irritated, rather than feeling supported. Increased staff workload resulted in negative perceptions and a consequent reluctance to use CAMMS. However, students who were causing concern reported subsequent improvement in attendance. CAMMS has the potential to identify 'at-risk' students at an early stage; however, the system should have flexibility to tailor automatically generated letters in response to individual circumstances, to

A case of the cauda equina syndrome complicating ankylosing spondylitis (AS) is described. An unusual feature of this case was the relapsing and remitting nature of the condition, but there is sufficient evidence to explain the clinical picture on the basis of a recurrent intraspinal inflammatory process. The clinical and radiological features are similar to those of a further 28 reported in the literature. An electromyogram (EMG) proved important in defining the extent of neurological involvement. Computerised tomography (CT) showed marked laminar erosion and no bony exit foramen encroachment. We believe that the clinical diagnosis of this condition can be adequately confirmed with plain radiology, EMG, and CT scan.

Computerised tomography (CT) is a favourite method of medical diagnosis. Its use has thus increased rapidly throughout the world, particularly in studies relating to children. However to avoid administering unnecessarily high doses of radiation to paediatric patients it is important to have correct dose reference levels to minimize risk. The research is being developed within the public health sector at the Hospital Infantil de Mexico ''Dr. Federico Gomez.'' We measured the entrance surface air kerma (K P ) in paediatric patients, during the radiological studies of control in CT (studies of head, thorax and abdomen). Phantom was used to evaluate image quality as the tomograph requires a high resolution image in order to operate at its optimum level

Order communication systems (OCS) are computer applications used to enter diagnostic and therapeutic patient care orders and to view test results. Many potential benefits of OCS have been identified including improvements in clinician ordering patterns, optimisation of clinical time, and aiding communication processes between clinicians and different departments. Many OCS now include computerised decision support systems (CDSS), which are information systems designed to improve clinical decision-making. CDSS match individual patient characteristics to a computerised knowledge base, and software algorithms generate patient-specific recommendations. To investigate which CDSS in OCS are in use within the UK and the impact of CDSS in OCS for diagnostic, screening or monitoring test ordering compared to OCS without CDSS. To determine what features of CDSS are associated with clinician or patient acceptance of CDSS in OCS and what is known about the cost-effectiveness of CDSS in diagnostic, screening or monitoring test OCS compared to OCS without CDSS. A generic search to identify potentially relevant studies for inclusion was conducted using MEDLINE, EMBASE, Cochrane Controlled Trials Register (CCTR), CINAHL (Cumulative Index to Nursing and Allied Health Literature), DARE (Database of Abstracts of Reviews of Effects), Health Technology Assessment (HTA) database, IEEE (Institute of Electrical and Electronic Engineers) Xplore digital library, NHS Economic Evaluation Database (NHS EED) and EconLit, searched between 1974 and 2009 with a total of 22,109 titles and abstracts screened for inclusion. CDSS for diagnostic, screening and monitoring test ordering OCS in use in the UK were identified through contact with the 24 manufacturers/suppliers currently contracted by the National Project for Information Technology (NpfIT) to provide either national or specialist decision support.

The Model for Radionuclide Migration in Urban Environment and Drainage Systems aims to estimate the discharge of radioactivity removed by natural or forced decontamination into the receiving waters from the drainage system, as well as the radioactivity joined with the sludge produced in treatments plants, whose various applications can mean a potential hazard. This model, built in Powersim, is included in the MOIRA system, a project whose main aim is the evaluation of the situation after a radioactive contamination of the aquatic ecosystems and the estimation of optimal remedial strategies to restore the contaminated waters. Powersim is an easy-to-use software package which simulates dynamic processes. Two sub-models compose the global model: one, simulating the evolution of Cs-137 in urban areas, and the other, the behaviour of this radionuclide, once it ha entered the drainage systems, with the various existing alternatives of waste water treatment in Europe.

TEM validation of immunohistochemical staining prior to assessment of tumour angiogenesis by computerised image analysis

International Nuclear Information System (INIS)

Killingsworth, M.C.

2002-01-01

Full text: Counts of microvessel density (MVD) within solid tumours have been shown to be an independent predictor of outcome with higher counts generally associated with a worse prognosis. These assessments are commonly performed on immunoperoxidase stained (IPX) sections with antibodies to CD34, CD31 and Factor VIII-related antigen routinely used as vascular markers. Tumour vascular density is thought to reflect the demand the growing neoplasm is placing on its feeding blood supply. Vascular density also appears to be associated with spread of invasive cells to distant sites. The present study of tumour angiogenesis in prostate cancer specimens aims to assess new vessel growth in addition to MVD counts. The hypothesis being that an assessment which takes into account vascular migration and proliferation as well as the number of patent vessels present may have improved predictive power over assessments based on MVD counts alone. We are employing anti-CD34 stained IPX sections which are digitally photographed and assessed by a computerised image analysis system. Our aim is to develop parameters whereby tumour angiogenesis may be assessed at the light microscopic level and then correlated with existing histological methods of tumour assessment such as Gleason grading. In order to use IPX stained sections for angiogenic assessment validation and understanding of the anti-CD34 immunostaining pattern was necessary. This involved the following steps: i) Morphological assessment of angiogenic changes present in tumour blood vessels. Morphological changes in endothelial cells and pericytes indicative of angiogenic activation are generally below the level of resolution available with light microscopy. TEM examination revealed endothelial cell budding, pericyte retraction, basement membrane duplication and endothelial sprout formation in capillaries and venules surrounding tumour glands. This information assisted with the development of parameters by which IPX sections

SCAN- a maintenance-free flowrate meter with direct digital read-out for computerised control applications in radiochemical plants

In radiochemical plants, the choice of flowrate sensor is subject to stringent requirements of fail-safe design and freedom from maintenance. The SCAN remote digital direct indicating flowrate meter described in this paper was developed to meet the requirements of flowrate and transmitting it to the control room, and to a computerised control system. SCAN is designed on the principle that flowrate through an orifice is a function of the head of liquid acting upon it. SCAN consists of a small chamber which receives the flow, and discharges it through an orifice located in bottom. The level of liquid in the pot represents the flowrate of the input stream. SCAN has been developed into an accurate, rugged and practical device by refinements in the design of internals, and by introducing a special end-section which makes the calibration insensitive to location. An important feature of SCAN is that it is passive, maintenance free, fail-safe device and contains no moving parts. There is no liquid hold up in the SCAN when idle, which is a desirable feature for the radiochemical plant environment. (author). 3 figs., 2 tabs.

Optimised performance of industrial high resolution computerised tomography

International Nuclear Information System (INIS)

2000-01-01

The purpose of non-destructive evaluation (NDE) is to acquire knowledge of the investigated sample. Digital x-ray imaging techniques such as radiography or computerised tomography (CT) produce images of the interior of a sample. The obtained image quality determines the possibility of detecting sample related features, e.g. details and flaws. This thesis presents a method of optimising the performance of industrial X-ray equipment for the imaging task at issue in order to obtain images with high quality. CT produces maps of the X-ray linear attenuation of the sample's interior. CT can produce two dimensional cross-section images or three-dimensional images with volumetric information on the investigated sample. The image contrast and noise depend on both the investigated sample and the equipment and settings used (X-ray tube potential, X-ray filtration, exposure time, etc.). Hence, it is vital to find the optimal equipment settings in order to obtain images of high quality. To be able to mathematically optimise the image quality, it is necessary to have a model of the X-ray imaging system together with an appropriate measure of image quality. The optimisation is performed with a developed model for an X-ray image-intensifier-based radiography system. The model predicts the mean value and variance of the measured signal level in the collected radiographic images. The traditionally used measure of physical image quality is the signal-to-noise ratio (SNR). To calculate the signal-to-noise ratio, a well-defined detail (flaw) is required. It was found that maximising the SNR leads to ambiguities, the optimised settings found by maximising the SNR were dependent on the material in the detail. When CT is performed on irregular shaped samples containing density and compositional variations, it is difficult to define which SNR to use for optimisation. This difficulty is solved by the measures of physical image quality proposed here, the ratios geometry

A Computerised Mapping Programme (CMP) was created step by step to cover all the needs of a cross sectional population survey conducted in eight villages of Fokida, a rural area of central Greece. The maps of Greece (boundary) and the topographical maps of the eight villages were created using the CMP. A volunteer sample of 1121 out of 2607 inhabitants of the study area participated in the population survey. The participants were tested for brucellosis using serological tests (ELISA and Rose Bengal) and the intradermal reaction test. A questionnaire was used to obtain information concerning the risk factors for brucellosis. The risk factors found through statistical analysis were occupation (RR: 5.81, p < 0.00001), consumption of raw milk (RR: 1.98, p < 0.001) and unpasteurized fresh cheese (RR: 2.13, p < 0.01). The same factors were indicated by the CMP. The CMP also indicated manure-contaminated playgrounds in residential yards as a potential risk factor for children. The origin and dissemination were delineated using time-space association display. The CMP proved to be a useful tool in this epidemiological study

A general approach to transform a lake model for one radionuclide (radiocesium) to another (radiostrontium) and critical model tests using data for four Ural lakes contaminated by the fallout from the Kyshtym accident in 1957

This paper presents results of a model test carried out within the framework of the COMETES project (EU). The aim of the work was to change the structure of the MOIRA lake model for radiocesium so that it can be applied more generally for, in principle, all types of radionuclides and heavy metals. This general lake model is used within the MOIRA decision support system (DSS; MOIRA and COMETES are acronyms for EU-projects). The model is based on a set of differential equations and a specific modelling structure. It incorporates all important fluxes to, from and within lakes in a general manner. Yet the model is driven by a minimum of variables accessible from standard maps and monitoring programs. The model can be separated into two parts, a general part with equations applicable for all types of water pollutants and a substance-specific part. This model has previously been validated for {sup 137}Cs from many lakes covering a wide domain and yielded excellent predictive power. The alterations discussed in this work are meant to be general and radiostrontium is used as a typical element. Radiostrontium is known to be more mobile than radiocesium and all abiotic parts of the model handling fixation and mobility have been altered. The new model for {sup 90}Sr has been critically tested using data from four lakes heavily contaminated with {sup 90}Sr from the Kyshtym accident in the Southern Urals, Russia, using empirical data from a period from 1958 to 1995 for {sup 90}Sr in fish (here goldfish), water and sediments.

A validation study of a computerised test recently developed involving the Stroop effect, extended here by inclusion of a third, more difficult test series, is presented. Three groups of men belonging to the Swedish armed forces and adjudged to differ in their qualifications (20, 32, and 19 men of levels 1, 2, and 3, respectively) and a fourth group of 18 men convicted of serious crimes of violence were given this test, termed the Stress Strategy Test. Discriminant analysis of the test's 12 variables (four for each of the three test series) yielded a discriminant power of 65% for the total group, highest for the level 1 group (80%) and for the nonmilitary group (72%), results substantially better than obtained for the original version of the test with use of similar subject groups.

IMPACT OF A COMPUTERISED OUTPATIENT PRESCRIPTION PRINTING SYSTEM (COPPS) ON MELATONIN PRESCRIBING IN A COMMUNITY CHILD HEALTH CLINIC.

Science.gov (United States)

Webb, Liz; Skingle, Jum

2016-09-01

COPPS is a computerised outpatient prescription printing system for WP10 prescriptions. It aims to improve the quality and safety of service, as patients will be provided with a legible, complete prescription to take to a community pharmacy of their choice. Patients requiring specialist medicines will have their medicines dispensed more promptly by the hospital pharmacy or medicines home care provider. The software ensures prescriptions contain all the required information to allow safe dispensing, reducing frequency of delays. Hospital pharmacy staff have more time to explain their medicines to patients, promoting shared decision making and improved adherence leading to better health outcomes and reduced waste and harm; provide information at the time of prescribing to increase adherence to agreed care pathways and prescribing practice. It facilitates attribution of prescribing, improves governance and is more easily audited and reported; capture the costs of medicines dispensed for out-patients which will be measured using information from the hospital pharmacy computer system and CASPA.The aim of this audit was to evaluate the effect the introduction of COPPS has had on compliance with the UHB formulary, local melatonin pathway and its impact on expenditure for melatonin within the community child health clinic. The pathway states that the starting dose is 2 mg Circadin® tablet or liquid melatonin 1 mg/1 ml if necessary for individual patients. Community Child Health prescribing data shows their highest expenditure is on melatonin. This was therefore chosen to test the impact of COPPS for a pilot study.Six months prescribing data (September 14-March 15) was obtained from COPPS. This was compared to data obtained for WP10's from hospital forms analysis for the same months the previous year (September 13-March 14) RESULTS: A 55% reduction was seen in the prescribing of non-formulary melatonin and a reduction in expenditure on melatonin by 18% or £16

The state system of accounting and control of nuclear material in Argentina and the Y2K issue

International Nuclear Information System (INIS)

Moreno, S.F.; Maceiras, E.

1999-01-01

The nuclear regulatory activities in Argentina are carried out by the 'Nuclear Regulatory Authority' (ARN). To fulfil its responsibilities, the ARN has established and enforced a regulatory framework for all nuclear activities concerning nuclear safety and radiological protection, physical protection and the guarantees of non-proliferation. Concerning the guarantees of non-proliferation, the SSAC includes an independent verification system based on national safeguards inspections, evaluations and a centralised accounting database of all nuclear materials in all nuclear activities performed in Argentina. The ARN has implemented two computerised databases to improve its SSAC. One is the 'Safeguards Inspections System' (SIS) developed to optimise the programming of the national inspections and their evaluation. The other is the 'Nuclear Material Control System' (SCMN) designed to improve the issuing and submission of accounting and operating reports. To improve further the SSAC, the ARN has requested software that should be in use at each nuclear installation in the near future. This computerised accounting database (SOP) would increase the quality of the operator's accounting and control system. About the change of the millennium, it is important to bear in mind that it may have an impact not only in the dates of the safeguards reports, but also in some data generated by software or equipment at nuclear installations used as the basis for safeguards records. For example, computerised programs for fuel element management at the Nuclear Power Stations or certain software and hardware in use at bulk installations would require a comprehensive review to assure that the change of the year 2000 will not cause any problem. Besides, some of the data generated by computerised systems at the level of installations are inputs for the three integrated databases SCMN, SIS and SOP. This paper describes the objectives and functions of these integrated systems and some main aspects

2012-01-01

Occupational Health Doctors active in building sector firms frequently have to evaluate residual workers' osteomuscular function in patients coming back to work after an accident happened during work time or free time. Definition of their specific individual work suitability is usually carried out utilizing semeiotic tests in which subjective evaluation of every single Medical Doctor is real important in definition of final results and this fact can cause legal controversies. In our research we describe the application of computerised movement analysis on 10 workers of building sector. In every patient examined this technical method has been able to study objectively the tridimensional ranges of motion of most important osteomuscular districts. The possibility to have an objective evaluation of residual osteomuscular function has a relevant importance both in definition of workers' work suitability at the moment in which they start again their activities and in possible future legal conflicts.

Background Inappropriate antimicrobial use has been shown to be an important determinant of the emergence of antimicrobial resistance (AMR). Health information technology (HIT) in the form of Computerised Decision Support (CDS) represents an option for improving antimicrobial prescribing and containing AMR. Objectives To evaluate the evidence for CDS in improving quantitative and qualitative measures of antibiotic prescribing in inpatient hospital settings. Methods A systematic literature search was conducted of articles published from inception to 20th December 2014 using eight electronic databases: MEDLINE, EMBASE, PUBMED, Web of Science, CINAHL, Cochrane Library, HMIC and PsychINFo. An updated systematic literature search was conducted from January 1st 2015 to October 1st 2016 using PUBMED. The search strategy used combinations of the following terms: (electronic prescribing) OR (clinical decision support) AND (antibiotic or antibacterial or antimicrobial) AND (hospital or secondary care or inpatient). Studies were evaluated for quality using a 10-point rating scale. Results Eighty-one studies were identified matching the inclusion criteria. Seven outcome measures were evaluated: adequacy of antibiotic coverage, mortality, volume of antibiotic usage, length of stay, antibiotic cost, compliance with guidelines, antimicrobial resistance, and CDS implementation and uptake. Meta-analysis of pooled outcomes showed CDS significantly improved the adequacy of antibiotic coverage (n = 13; odds ratio [OR], 2.11 [95% CI, 1.67 to 2.66, p ≤ 0.00001]). Also, CDS was associated with marginally lowered mortality (n = 20; OR, 0.85 [CI, 0.75 to 0.96, p = 0.01]). CDS was associated with lower antibiotic utilisation, increased compliance with antibiotic guidelines and reductions in antimicrobial resistance. Conflicting effects of CDS on length of stay, antibiotic costs and system uptake were also noted. Conclusions CDS has the potential to improve the adequacy of antibiotic

Background Despite the evidence base for computer-assisted cognitive-behavioural therapy (CBT) in the general population, it has not yet been adapted for use with adults who have an intellectual disability. Aims To evaluate the utility of a CBT computer game for adults who have an intellectual disability. Method A 2 × 3 (group × time) randomised controlled trial design was used. Fifty-two adults with mild to moderate intellectual disability and anxiety or depression were randomly allocated to two groups: computerised CBT (cCBT) or psychiatric treatment as usual (TAU), and assessed at pre-treatment, post-treatment and 3-month follow-up. Forty-nine participants were included in the final analysis. Results A significant group × time interaction was observed on the primary outcome measure of anxiety (Glasgow Anxiety Scale for people with an Intellectual Disability), favouring cCBT over TAU, but not on the primary outcome measure of depression (Glasgow Depression Scale for people with a Learning Disability). A medium effect size for anxiety symptoms was observed at post-treatment and a large effect size was observed after follow-up. Reliability of Change Indices indicated that the intervention produced clinically significant change in the cCBT group in comparison with TAU. Conclusions As the first application of cCBT for adults with intellectual disability, this intervention appears to be a useful treatment option to reduce anxiety symptoms in this population. © The Royal College of Psychiatrists 2017.

The goal of this study is to evaluate the effectiveness of a computerised working memory (WM) training on memory, response inhibition, fluid intelligence, scholastic abilities and the recall of stories in adolescents with mild to borderline intellectual disabilities attending special education. A total of 95 adolescents with mild to borderline intellectual disabilities were randomly assigned to either a training adaptive to each child's progress in WM, a non-adaptive WM training, or to a control group. Verbal short-term memory (STM) improved significantly from pre- to post-testing in the group who received the adaptive training compared with the control group. The beneficial effect on verbal STM was maintained at follow-up and other effects became clear at that time as well. Both the adaptive and non-adaptive WM training led to higher scores at follow-up than at post-intervention on visual STM, arithmetic and story recall compared with the control condition. In addition, the non-adaptive training group showed a significant increase in visuo-spatial WM capacity. The current study provides the first demonstration that WM can be effectively trained in adolescents with mild to borderline intellectual disabilities.

Applying modern psychometric techniques to melodic discrimination testing: Item response theory, computerised adaptive testing, and automatic item generation.

Science.gov (United States)

Harrison, Peter M C; Collins, Tom; Müllensiefen, Daniel

2017-06-15

Modern psychometric theory provides many useful tools for ability testing, such as item response theory, computerised adaptive testing, and automatic item generation. However, these techniques have yet to be integrated into mainstream psychological practice. This is unfortunate, because modern psychometric techniques can bring many benefits, including sophisticated reliability measures, improved construct validity, avoidance of exposure effects, and improved efficiency. In the present research we therefore use these techniques to develop a new test of a well-studied psychological capacity: melodic discrimination, the ability to detect differences between melodies. We calibrate and validate this test in a series of studies. Studies 1 and 2 respectively calibrate and validate an initial test version, while Studies 3 and 4 calibrate and validate an updated test version incorporating additional easy items. The results support the new test's viability, with evidence for strong reliability and construct validity. We discuss how these modern psychometric techniques may also be profitably applied to other areas of music psychology and psychological science in general.

Assessment of the environmental and radiological consequences of a nuclear accident requires the management of a great deal of data and information as well as the use of predictive models. Computerised Decision Support Systems (CDSS) are essential tools for this kind of complex assessment and for assisting experts with a rational decision process. The present work focuses on the assessment of the main features of selected state-of-the-art CDSS for off-site management of freshwater ecosystems contaminated by radionuclides. This study involved both developers and end-users of the assessed CDSS and was based on practical customisation exercises, installation and application of the decision systems. Potential end-users can benefit from the availability of several ready-to-use CDSS that allow one to run different kinds of models aimed at predicting the behaviour of radionuclides in aquatic ecosystems, evaluating doses to humans, assessing the effectiveness of different kinds of environmental management interventions and ranking these interventions, accounting for their social, economic and environmental impacts. As a result of the present assessment, the importance of CDSS 'integration' became apparent: in many circumstances, different CDSS can be used as complementary tools for the decision-making process. The results of this assessment can also be useful for the future development and improvement of the CDSS. - Research highlights: →The present work focuses on the assessment of the main features of selected state-of-the-art CDSS for the off-site management of freshwater ecosystems contaminated by radionuclides. →Potential end-users can benefit from a number of complementary open, freely-available and ready-to-use CDSS based on validated environmental models aimed at predicting the migration of radionuclides in the aquatic environment, evaluating the doses to man, assessing the effectiveness of different environmental feasible restoration strategies and

Colonoscopy and computerised tomography scan are not sufficient to localise right sided colonic lesions accurately.

LENUS (Irish Health Repository)

Solon, Jacqueline Gemma

2009-11-23

: Aim: accurate pre-operative localisation of colonic lesions is critical especially in laparoscopic colectomy where tactile localisation is absent particularly in screen-detected tumours. The study aimed to evaluate the accuracy of colonoscopy and double-contrast computerised tomography (CT) to localise lesions treated by right hemicolectomy. Method: a retrospective chart review was performed of patients treated by right hemicolectomy under the colorectal service between July 2003 and October 2006. Pre-operative tumour location determined by CT scan and colonoscopy were compared with the intra-operative and histopathologic findings. Results: of 101 patients, 73 (73%) were for adenoma or cancer, with a final diagnosis of adenocarcinoma in 59 (59%). Pre-operative localisation was inaccurate in 29% of lesions using both CT and colonoscopy. In the transverse colon colonoscopy alone was only 37.5% accurate, increasing to 62.5% when information from the CT scan was added. Conclusion: pre-operative localisation of right-sided colon cancers using colonoscopy and CT scanning is unreliable in at least 29% of cases. Inaccurate localisation of transverse colon tumours risks inadequate lymphadenectomy with an adverse cancer outcome. Pre-operative abdominal CT scan improves accuracy but endoscopic tattoo localisation should be employed routinely especially in patients undergoing laparoscopic resection.

Demonstrating the effectiveness of body armour: a pilot prospective computerised surface wound mapping trial performed at the Role 3 hospital in Afghanistan.

Modern body armour clearly reduces injury incidence and severity, but evidence to actually objectively demonstrate this effect is scarce. Although the Joint Theatre Trauma Registry (JTTR) alone cannot relate injury pattern to body armour coverage, the addition of computerised Surface Wound Mapping (SWM) may enable this utility. Surface wound locations of all UK and NATO coalition soldiers, Afghan National Army and Police and local nationals injured by explosively propelled fragments and treated in the Role 3 UK-led Field Hospital in Camp Bastion, Afghanistan, between 8 July and 20 October 2012 were prospectively recorded. The Abbreviated Injury Scores (AIS) and relative risk of casualties sustaining injuries under a type of body armour were compared with those that did not wear that armour. Casualties wearing a combat helmet were 2.7 times less likely to sustain a fragmentation wound to the head than those that were unprotected (mean AIS of 2.9 compared with 4.1). Casualties wearing a body armour vest were 4.1 times less likely to sustain a fragmentation wound to the chest or abdomen than those that were unprotected (mean AIS of 2.9 compared with 3.9). Casualties wearing pelvic protection were 10 times less likely to sustain a fragmentation wound to the pelvis compared with those that were unprotected (mean AIS of 3.4 compared with 3.9). Computerised SWM has objectively demonstrated the ability of body armour worn on current operations in Afghanistan to reduce wound incidence and severity. We recognise this technique is limited in that it only records the surface wound location and may be specific to this conflict. However, gathering electronic SWM at the same time as recording injuries for the JTTR was simple, required little extra time and therefore we would recommend its collection during future conflicts.

Post-mortem examination of 16 donkey cheek teeth (CT) with caries (both peripheral and infundibular) and pulpar exposure were performed using computerised axial tomography (CAT), histology and scanning electron microscopy. CAT imaging was found to be useful to assess the presence and extent of caries and pulp exposure in individual donkey CT. Histology identified the loss of occlusal secondary dentine, and showed pulp necrosis in teeth with pulpar exposure. Viable pulp was present more apically in one exposed pulp horn, with its occlusal aspect sealed off from the exposed aspect of the pulp horn by a false pulp stone. Scanning electron microscopy showed the amelo-cemental junction to be a possible route of bacterial infection in infundibular cemental caries. The basic pathogenesis of dental caries in donkeys appears very similar to its description in other species.

To devise a new protocol for targeted CT scanning of the distal tibiofibular syndesmosis with minimal radiation exposure to patients. We also aimed to correlate the reduction of the syndesmosis as seen on CT scans with the functional outcome of patients. Prospective study. Forty adults undergoing surgical stabilisation of an acute distal tibiofibular syndesmosis injury were recruited. A targeted five-cut computerised tomography scan protocol was developed. The radiation exposure to the patient with this protocol was only 0.002 mSv. Scans were performed 12 weeks after surgery. The contralateral ankle of every patient was used as a control to determine the accuracy of the reduction of the syndesmosis for that individual patient. American Orthopaedic Foot and Ankle Society (AOFAS) scores were obtained at a minimum of 1 year after surgery. After considering the exclusions, 36 patients formed the study group. A wide variation was observed in the anatomy of the normal syndesmosis. If we considered a difference of more than 2 mm between the normal and injured syndesmosis relationship as significant, 15 (41.6 %) of our patients had a significant difference between the injured and normal sides. AOFAS scores were available for 13 of these patients and were good to excellent in 11(84.6 %). Our study describes a reliable new CT scanning technique for the distal tibiofibular syndesmosis using only five cuts and a low-radiation-dose protocol. Clinical correlation of the findings on the scan with functional outcomes suggests that routine post-operative CT of the syndesmosis is probably not justified. (orig.)

2015-01-01

A radiological model for 137 Cs and 90 Sr dispersion in the marine environment of the Thermaikos Gulf, Greece, and the river catchments draining into the Gulf, is presented. The model, developed and implemented within the MOIRA-PLUS decision support system, integrates appropriate site-specific information. The model's performance has been tested using the available empirical 137 Cs activity concentration data in abiotic and biotic components of the gulf since the Chernobyl accident. Further, this paper describes the results of a modelling exercise performed within the IAEA's EMRAS II international modelling programme to estimate the environmental sensitivity of this characteristic Mediterranean coastal marine environment following radioactive contamination. The radiation doses to humans after a single hypothetical instantaneous deposition of 1000 Bq m −2 , assuming that all of their food intake from the marine pathway comes from the local environment, were calculated. The obtained results are consistent with estimates from other models for different coastal marine environments in the frame of the above-mentioned EMRAS exercise. - Highlights: • The Decision Support System (DSS) MOIRA-PLUS was customised to Thermaikos Gulf. • Model results were compared with empirical data to adjust parameter values. • The environmental sensitivity of the Gulf to 90 Sr and 137 Cs pollution was assessed. • Radiation doses from marine and fresh water pathways were compared. • The dose from fresh water pathways is notably higher than that from marine pathways

1995-01-01

The demand for electricity is ever increasing. The cost of electrical generation is rising. The cost of new generating station is prohibitive to the electricity boards. Financial excellence is only possible by implementing energy audit. Because of energy audit programs the consumers' attitude is bound to change. The theft and pilferage will be detected and the quantum is bound to reduce. Financial energy management system (FEMS) will look into all operations with reference to the energy sell, energy input, finance, equipment failure, interruptions and also the individual performances of each engineer in charge of that area. 2 tabs

McMenamin, John; Nicholson, Rick; Leech, Ken

2011-12-01

Clinical reminders have been shown to help general practice achieve an increase in some preventive care items, especially if they identify a patient's eligibility for the target item, prompt clinicians at the right time, provide a fast link to management tools and facilitate clinical recording. WRPHO has introduced the Patient Dashboard clinical reminder and monitored its impact on health targets. This paper reports the impact of a computerised colour-coded clinical reminder on achieving agreed health targets in Whanganui regional practices. Patient Dashboard was developed from previous versions in Auckland and Northland and provided to Whanganui regional practices with Primary Health Organisation (PHO) support. The Dashboard was linked with existing and new clinical management tools which automatically updated clinical records. Data from practices was pooled by Whanganui Regional Primary Health Organisation and target achievement rates reported over 15 months. Over the initial 15 months of Patient Dashboard use, recording of smoking status increased from 74% to 82% and of alcohol use from 15% to 47%. Screening for diabetes increased from 62% to 74%, cardiovascular risk assessment from 20% to 43%, cervical screening from 71% to 79%, and breast screening from 60% to 80%. Patient Dashboard was associated with increased performance indicators both for those targets which were part of a PHO programme and for targets without additional support.

1985-01-01

The original computerised system for monitoring the vibration of gags in each reactor channel of the Hinkley Point 'B' AGR Power Station did not meet the specification for a more stringent safety requirement. This paper describes the replacement of that original single processor system with an enhanced dual processor/multiple scanner computer system used to satisfy this new safety and reliability need. The specification and installation of the new hardware and software are discussed, and some of the problems encountered and their solutions are highlighted. (author)

Castro, A.; Buedo, J.L.; Borondo, L.; Lopez, N.

2001-01-01

Nuclear Power Plants (NPP) will have to be prepared to face the management of severe accidents, through the development of Severe Accident Guides and sophisticated systems of calculation, as a supporting to the decision-making. SISIFO-GAS is a flexible computerized tool, both for the supporting to accident management and for education and training in severe accident. It is an interactive system, a visual and an easily handle one, and needs no specific knowledge in MAAP code to make complicate simulations in conditions of severe accident. The system is configured and adjusted to work in a BWR/6 technology plant with Mark III Containment, as it is Cofrentes NPP. But it is easily portable to every other kind of reactor, having the level 2 PSA (probabilistic safety analysis) of the plant to be able to establish the categories of the source term and the most important sequences in the progression of the accident. The graphic interface allows following in a very intuitive and formative way the evolution and the most relevant events in the accident, in the both system's way of work, training and management.

New rehabilitation strategies for post-stroke upper limb rehabilitation employing visual stimulation show promising results, however, cost-efficient and clinically feasible ways to provide these interventions are still lacking. An integral step is to translate recent technological advances, such as in virtual and augmented reality, into therapeutic practice to improve outcomes for patients. This requires research on the adaptation of the technology for clinical use as well as on the appropriate guidelines and protocols for sustainable integration into therapeutic routines. Here, we present and evaluate a novel and affordable augmented reality system (Augmented Reflection Technology, ART) in combination with a validated mirror therapy protocol for upper limb rehabilitation after stroke. We evaluated components of the therapeutic intervention, from the patients' and the therapists' points of view in a clinical feasibility study at a rehabilitation centre. We also assessed the integration of ART as an adjunct therapy for the clinical rehabilitation of subacute patients at two different hospitals. The results showed that the combination and application of the Berlin Protocol for Mirror Therapy together with ART was feasible for clinical use. This combination was integrated into the therapeutic plan of subacute stroke patients at the two clinical locations where the second part of this research was conducted. Our findings pave the way for using technology to provide mirror therapy in clinical settings and show potential for the more effective use of inpatient time and enhanced recoveries for patients. Implications for Rehabilitation Computerised Mirror Therapy is feasible for clinical use Augmented Reflection Technology can be integrated as an adjunctive therapeutic intervention for subacute stroke patients in an inpatient setting Virtual Rehabilitation devices such as Augmented Reflection Technology have considerable potential to enhance stroke rehabilitation.

1991-01-01

The purpose of this paper is to show what we are doing in the area of environmental monitoring and control in accordance with the basic principles we set out for ourselves. As we have seen, our objectives are twofold; first, to monitor the installations under normal operating conditions in accordance with the rules and within the imposed limits and, secondly, in the event of an accident involving any of the material at the plant, to determine the foreseeable consequences in order to provide the relevant authorities, who have to take the necessary measures to protect the personnel and the population, with all the help they need. Normal operation is guaranteed by effective control of liquid and gaseous discharges, by knowing the precise origin and nature of the radio-elements released and also the means of transfer leading to humans. This knowledge relies upon the interpretation of the systematic measurements which have been carried out, which can only be done by centralising and computerising the data involved. The use of third-generation radio protection equipment in combination with highly-developed computer systems has made it possible to set up a centralised environmental control station. In the event of abnormal occurrences, the software used to show the transfer of radio-elements in the air, the water, or the ground, along with the use of systematic measurements, makes it possible to determine the foreseeable consequences and to design a system of predictive monitoring. It has been possible to set up the centralised control system because of the development in computerised equipment and systems, but it has only been possible to operate this system because of the capacity of the personnel to adapt to the changeover to technology.

There are high rates of mental disorder in correctional environments, so effective mental health screening is needed. Implementation of the computerised mental health screen of the Correctional Service of Canada has led to improved identification of offenders with mental health needs but with high rates of false positives. The goal of this study is to evaluate the use of an iterative classification tree (ICT) approach to mental health screening compared with a simple binary approach using cut-off scores on screening tools. A total of 504 consecutive admissions to federal prison completed the screen and were also interviewed by a mental health professional. Relationships between screening results and more extended assessment and clinical team discussion were tested. The ICT was more parsimonious in identifying probable 'cases' than standard binary screening. ICT was also highly accurate at detecting mental health needs (AUC=0.87, 95% CI 0.84-0.90). The model identified 118 (23.4%) offenders as likely to need further assessment or treatment, 87% of whom were confirmed cases at clinical interview. Of the 244 (48.4%) offenders who were screened out, only 9% were clinically assessed as requiring further assessment or treatment. Standard binary screening was characterised by more false positives and a comparable false negative rate. The use of ICTs to interpret screening data on the mental health of prisoners needs further evaluation in independent samples in Canada and elsewhere. This first evaluation of the application of such an approach offers the prospect of more effective and efficient use of the scarce resource of mental health services in prisons. Although not required, the use of computers can increase the ease of implementing an ICT model. Copyright © 2013 John Wiley & Sons, Ltd.

The use of computerised tomography guided percutaneous fine needle aspiration in the evaluation of solitary pulmonary nodules.

LENUS (Irish Health Repository)

Khan, K A

2012-02-01

The evaluation of a solitary pulmonary nodule (SPN) has changed over the years with increased access to percutaneous computerised tomography (CT) guided fine needle aspiration (FNA), where bronchoscopy is unhelpful. The aim of our study was to evaluate the sample adequacy, diagnostic and complication rate of CT-FNA of a SPN at our academic teaching hospital over an 18 month period. CT-FNA was performed by a radiologist, with a cytopathologist in attendance to confirm the adequacy of the sample obtained. The size of the nodule, sample material and adequacy, diagnosis and complications were recorded. A total of 101 patients were included, 54 male and the mean age was 68 +\\/- 11 years. The mean size of the SPN was 2.3 cm (range 1-11 cm). 56 (56%) patients had a right SPN, 45 (45%) had a left SPN. CT-FNA was diagnostic in 80 (80%) patients and non-diagnostic in 21 (20%) patients. The sample was insufficient for immunocytochemistry, although the morphological appearance was diagnostic in 20 (25%) of the 80 patients. Pneumothorax occurred in 26\\/101 (26%) patients post CT-FNA, of these 7 (27%) required chest drain insertion, while 19 (73%) were managed conservatively. CT FNA is a useful tool for the diagnosis of a SPN, with our diagnostic accuracy comparable to that reported in the literature. However, CT-FNA may not provide adequate sample volume to perform ancillary testing and has a moderate complication rate.

Retention index of thallium-201 single photon emission computerised tomography (SPECT) as an indicator of metastasis in adenocarcinoma of the lung.

We examined the relationship between the retention of thallium-201 (201Tl) on a delayed scan and the metastatic potential of adenocarcinomas of the lung. We studied 43 patients with adenocarcinoma of the lung and divided them into two groups according to the presence or absence of lymph node metastasis. 201Tl single photon emission computerised tomography (SPECT) was conducted twice: 15 min (early scan) and 120 min (delayed scan) after intravenous injection of 3 mCi of 201Tl chloride. We calculated the retention index in order to evaluate the degree of 201Tl retention in the primary tumour. The retention indices were significantly higher in the group that was positive for lymph node metastasis than in the negative group. In adenocarcinomas with high metastatic potential, 201Tl SPECT demonstrated slow washout or increased retention on the delayed scan. The retention index of 201Tl SPECT is a useful indicator of metastatic potential, thereby facilitating the prediction of prognosis, and provides insight into the relationship between 201Tl uptake and malignancy. This is the first report demonstrating a significant relationship between the retention of 201Tl SPECT and lymph node metastasis. Images Figure 1 PMID:8054281

Computers start to think with expert systems

Energy Technology Data Exchange (ETDEWEB)

1983-03-21

A growing number of professionals-notably in oil and mineral exploration, plasma research, medicine, VLSI circuit design, drug design and robotics-are beginning to use computerised expert systems. A computer program uses knowledge and inference procedures to solve problems which are sufficiently difficult to require significant human expertise for their solution. The facts constitute a body of information that is widely shared, publicly available and generally agreed upon by experts in the field. The heuristics are mostly private, and little discussed, rules of good judgement (rules of plausible reasoning, rules of good guessing, etc.) that characterise expert-level decision making in the field.

Split-mouth and parallel-arm trials to compare pain with intraosseous anaesthesia delivered by the computerised Quicksleeper system and conventional infiltration anaesthesia in paediatric oral healthcare: protocol for a randomised controlled trial.

Local anaesthesia is commonly used in paediatric oral healthcare. Infiltration anaesthesia is the most frequently used, but recent developments in anaesthesia techniques have introduced an alternative: intraosseous anaesthesia. We propose to perform a split-mouth and parallel-arm multicentre randomised controlled trial (RCT) comparing the pain caused by the insertion of the needle for the injection of conventional infiltration anaesthesia, and intraosseous anaesthesia by the computerised QuickSleeper system, in children and adolescents. Inclusion criteria are patients 7-15 years old with at least 2 first permanent molars belonging to the same dental arch (for the split-mouth RCT) or with a first permanent molar (for the parallel-arm RCT) requiring conservative or endodontic treatment limited to pulpotomy. The setting of this study is the Department of Paediatric Dentistry at 3 University dental hospitals in France. The primary outcome measure will be pain reported by the patient on a visual analogue scale concerning the insertion of the needle and the injection/infiltration. Secondary outcomes are latency, need for additional anaesthesia during the treatment and pain felt during the treatment. We will use a computer-generated permuted-block randomisation sequence for allocation to anaesthesia groups. The random sequences will be stratified by centre (and by dental arch for the parallel-arm RCT). Only participants will be blinded to group assignment. Data will be analysed by the intent-to-treat principle. In all, 160 patients will be included (30 in the split-mouth RCT, 130 in the parallel-arm RCT). This protocol has been approved by the French ethics committee for the protection of people (Comité de Protection des Personnes, Ile de France I) and will be conducted in full accordance with accepted ethical principles. Findings will be reported in scientific publications and at research conferences, and in project summary papers for participants. Clinical

We assessed the effects of a bar-code assisted medication administration system used without the support of computerised prescribing (stand-alone BCMA), on the dispensing process and its users. The stand-alone BCMA system was implemented in one ward of a teaching hospital. The number of dispensing steps, dispensing time and potential dispensing errors (PDEs) were directly observed one month before and eight months after the intervention. Attitudes of pharmacy and nursing staff were assessed using a questionnaire (Likert scale) and interviews. Among 1291 and 471 drug items observed before and after the introduction of the technology respectively, the number of dispensing steps increased from five to eight and time (standard deviation) to dispense one drug item by one staff personnel increased from 0.8 (0.09) to 1.5 (0.12) min. Among 2828 and 471 drug items observed before and after the intervention respectively, the number of PDEs increased significantly (Psystem offered less benefit to the dispensing process (9/16). Nursing staff perceived the system as useful in improving the accuracy of drug administration (7/10). Implementing a stand-alone BCMA system may slow down and complicate the dispensing process. Nursing staff believe the stand-alone BCMA system could improve the drug administration process but pharmacy staff believes the technology would be more helpful if supported by computerised prescribing. However, periodical assessments are needed to identify weaknesses in the process after implementation, and all users should be educated on the benefits of using this technology.

Spacer pads and bearing pads are resistance spot welded on PHWR fuel elements to ensure inter-element gap for coolant flow. These welds are subjected to destructive tests as per SQC specifications while qualifying a machine and during production. The testing machine used earlier over the years was tedious involving manual operations of clamping, tool actuation, increasing and decreasing the pressure, referring to charts and statistical calculations. To carry out the destructive testing of the welds conveniently and reliably, an automatic machine is developed in-house in which are incorporated a quartz force transducer and a computerized data-acquisition and processing system together with a very versatile electronic control system based on a single-chip microcomputer. This paper describes the salient features of the machine and the control system. (author). 4 figs

For total body irradiation (TBI) dose calculation requirements, anatomical information about the whole body is needed. Despite the fact that video image grabbing techniques are used by some treatment planning systems for standard radiotherapy, there are no such systems designed to generate anatomical parameters for TBI planning. The paper describes an anthropometrical computerised system based on video image grabbing which was purpose-built to provide anatomical data for a PC-based TBI planning system. Using software, the system controls the acquisition and digitalisation of the images (external images of the patient in treatment position) and the measurement procedure itself (on the external images or the digital CT information). An ASCII file, readable by the TBI planning system, is generated to store the required parameters of the dose calculation points, i.e. depth, backscatter tissue thickness, thickness of inhomogeneity, off-axis distance (OAD) and source to skin distance (SSD).

Computerised tomography (CT) is a powerful tool in medicine, and would be well suited to a wide range of industrial applications, particularly non-destructive testing. However, the very diversity of uses makes the production of a standardised scanner impossible. Systems for an industrial use will have to be designed with a problem in mind. An approach is presented for the analysis of CT scanning systems to help in the design problem. It first describes a system in terms of the sampling of the Radon transform of the object and then uses this information to produce a spatial description of the performance of a scanning system in terms of data collection. This description is called a resolution map and it is shown how the resolution map can be related to the object under study. (author)

From conventional software based systems to knowledge based systems

1995-01-01

Even if todays nuclear power plants have a very good safety record, there is a continuous search for still improving safety. One direction of this effort address operational safety, trying to improve the handling of disturbances and accidents partly by further automation, partly by creating a better control room environment, providing the operator with intelligent support systems to help in the decision making process. Introduction of intelligent computerised operator support systems has proved to be an efficient way of improving the operators performance. A number of systems have been developed worldwide, assisting in tasks like process fault detection and diagnosis, selection and implementation of proper remedial actions. Unfortunately, the use of Knowledge Based Systems (KBSs), introduces a new dimension to the problem of the licensing process. KBSs, despite the different technology employed, are still nothing more than a computer program. Unfortunately, quite a few people building knowledge based systems seem to ignore the many good programming practices that have evolved over the years for producing traditional computer programs. In this paper the author will try to point out similarities and differences between conventional software based systems, and knowledge based systems, introducing also the concept of model based reasoning.

Full Text Available Abstract Background NICE recommends computerised cognitive behavioural therapy (cCBT for the treatment of several mental health problems such as anxiety and depression. cCBT may be one way that services can reduce waiting lists and improve capacity and efficiency. However, there is some doubt about the extent to which the National Health Service (NHS in the UK is embracing this new health technology in practice. This study aimed to investigate Scottish health service infrastructure and policies that promote or impede the implementation of cCBT in the NHS. Methods A telephone survey of lead IT staff at all health board areas across Scotland to systematically enquire about the ability of local IT infrastructure and IT policies to support delivery of cCBT. Results Overall, most of the health boards possess the required software to use cCBT programmes. However, the majority of NHS health boards reported that they lack dedicated computers for patient use, hence access to cCBT at NHS sites is limited. Additionally, local policy in the majority of boards prevent staff from routinely contacting patients via email, skype or instant messenger, making the delivery of short, efficient support sessions difficult. Conclusions Conclusions: Overall most of the infrastructure is in place but is not utilised in ways that allow effective delivery. For cCBT to be successfully delivered within a guided support model, as recommended by national guidelines, dedicated patient computers should be provided to allow access to online interventions. Additionally, policy should allow staff to support patients in convenient ways such as via email or live chat. These measures would increase the likelihood of achieving Scottish health service targets to reduce waiting time for psychological therapies to 18 weeks.

Chronic pain is associated with reduced efficiency of cognitive performance, and few studies have investigated methods of remediation. We trialled a computerised cognitive training protocol to determine whether it could attenuate cognitive difficulties in a chronic pain sample. Thirty-nine adults with chronic pain (mean age = 43.3, 61.5% females) were randomised to an 8-week online course (3 sessions/week from home) of game-like cognitive training exercises, or an active control involving watching documentary videos. Participants received weekly supervision by video call. Primary outcomes were a global neurocognitive composite (tests of attention, speed, and executive function) and self-reported cognition. Secondary outcomes were pain (intensity; interference), mood symptoms (depression; anxiety), and coping with pain (catastrophising; self-efficacy). Thirty participants (15 training and 15 control) completed the trial. Mixed model intention-to-treat analyses revealed significant effects of training on the global neurocognitive composite (net effect size [ES] = 0.43, P = 0.017), driven by improved executive function performance (attention switching and working memory). The control group reported improvement in pain intensity (net ES = 0.65, P = 0.022). Both groups reported subjective improvements in cognition (ES = 0.28, P = 0.033) and catastrophising (ES = 0.55, P = 0.006). Depression, anxiety, self-efficacy, and pain interference showed no change in either group. This study provides preliminary evidence that supervised cognitive training may be a viable method for enhancing cognitive skills in persons with chronic pain, but transfer to functional and clinical outcomes remains to be demonstrated. Active control results suggest that activities perceived as relaxing or enjoyable contribute to improved perception of well-being. Weekly contact was pivotal to successful program completion.

The concept of an integrated quality record nuclear material accountancy system

International Nuclear Information System (INIS)

Von Wachtendonk, H.J.

1987-01-01

RBU had already started in 1976 with the computerisation of its nuclear material accountancy system. It used the hardware and the software which were at hand at that time. The development of the software needed about 3 years, and so, the system, was fully introduced in 1979 and has been used since then with only minor changes. But with the time, the overwhelming progress in computer and software technology has overcome the existing system. Upgrading the old system would need a lot of effort, so RBU decided to modernize its system fundamentally. In the time between RBU has developed a quality record and documentation system for the purposes of quality assurance and quality control. This system shall be enlarged, so that it can overtake the tasks of NMA, too. The quality record system contains already nearly 80 % of all NMA-relevant data. The presented paper will describe the main changes between the present and the future system

Internet technologies in the mining industry. Towards unattended mining systems

Energy Technology Data Exchange (ETDEWEB)

Krzykawski, Michal [FAMUR Group, Katowice (Poland)

2009-08-27

Global suppliers of longwall systems focus mainly on maximising the efficiency of the equipment they manufacture. Given the fact that, since 2004, coal demand on world markets has been constantly on the increase, even during an economic downturn, this endeavour seems fully justified. However, it should be remembered that maximum efficiency must be accompanied by maximum safety of all underground operations. This statement is based on the belief that the mining industry, which exploits increasingly deep and dangerous coal beds, faces the necessity to implement comprehensive IT systems for managing all mining processes and, in the near future, to use unmanned mining systems, fully controllable from the mine surface. The computerisation of mines is an indispensable element of the development of the world mining industry, a belief which has been put into practice with e-mine, developed by the FAMUR Group. (orig.)

Handbook for replacement of process control systems in thermal power plants; Handbok - Utbytesbehov i kontrollsystem foer vaermekraftverk

Modernization of control equipment in more complex power plants, such as thermal power plants, requires special attention due to the almost complete change-over to new computerised technology. The introduction of new technology gives rise to great changes in both the process control systems and in operation and maintenance routines. The change-over to computerised technology also causes lack of spare parts and service for older equipment. The older technology becomes obsolete due to the great advantages that comes with new technology. Therefore, the lifetime of control equipment is not only coupled to traditional ageing and wear, such as oxidation and fatigue of material, but also to the fact that the old equipment is getting out of date. It becomes more and more common that this out-of-date factor, rather than ageing, sets the limit for the useful life of the equipment. The Handbook for replacement of process control systems in thermal power plants is thought to be a first help for engineers and managers who has the responsibility for process control modernization. The Handbook points out the factors that determines the service life of the control equipment. It also suggests what information is required in order to take a decision on modernization. The Handbook at its present form constitutes a first approach that leaves room for an extension later on. Any request to expand the Handbook should be put forward to Vaermeforsk or its partners

Cyber security in nuclear power plants and its portability to other industrial infrastructures

2017-01-01

Power generation increasingly relies on decentralised and interconnected computerised systems. Concepts like ''Industrial Internet of Things'' of the Industrial Internet Consortium (IIC), and ''Industry 4.0'' find their way in this strategic industry. Risk of targeted exploits of errors and vulnerabilities increases with complexity, interconnectivity and decentralization. Inherently stringent security requirements and features make nuclear computerised applications and systems a benchmark for industrial counterparts seeking to hedge against those risks. Consequently, this contribution presents usual cyber security regulations and practices for nuclear power plants. It shows how nuclear cyber security can be ported and used in an industrial context to protect critical infrastructures against cyber-attacks and industrial espionage.

The design and implementation of an Interactive Computerised Decision Support Framework (ICDSF) as a strategy to improve nursing students' clinical reasoning skills.

Hoffman, Kerry; Dempsey, Jennifer; Levett-Jones, Tracy; Noble, Danielle; Hickey, Noelene; Jeong, Sarah; Hunter, Sharyn; Norton, Carol

2011-08-01

This paper describes the conceptual design and testing of an Interactive Computerised Decision Support Framework (ICDSF) which was constructed to enable student nurses to "think like a nurse." The ICDSF was based on a model of clinical reasoning. Teaching student nurses to reason clinically is important as poor clinical reasoning skills can lead to "failure-to rescue" of deteriorating patients. The framework of the ICDSF was based on nursing concepts to encourage deep learning and transferability of knowledge. The principles of active student participation, situated cognition to solve problems, authenticity, and cognitive rehearsal were used to develop the ICDSF. The ICDSF was designed in such a way that students moved through it in a step-wise fashion and were required to achieve competency at each step before proceeding to the next. The quality of the ICDSF was evaluated using a questionairre survey, students' written comments and student assessment measures on a pilot and the ICDSF. Overall students were highly satisfied with the clinical scenarios of the ICDSF and believed they were an interesting and useful way to engage in authentic clinical learning. They also believed the ICDSF was useful in developing cognitive skills such as clinical reasoning, problem-solving and decision-making. Some reported issues were the need for good technical support and the lack of face to face contact when using e-learning. Some students also believed the ICDSF was less useful than actual clinical placements. Copyright © 2010 Elsevier Ltd. All rights reserved.

X-ray imaging system

International Nuclear Information System (INIS)

Houston, J.M.

1980-01-01

A novel, high-speed apparatus for use in X-ray computerised tomography is described in detail. It consists of a semi-circular array of X-ray sources, collimators and an ion chamber array for detection of the X-rays. The X-ray sources may be pulsed in salvos such that the corresponding detectors in the array are only illuminated by one source. The use of computer controlled salvos speeds up the image processing by at least a factor of two. The ion chamber array is designed to have a constant detection efficiency for varying angles of X-ray incidence. A detailed description of the detector construction and suggested gaseous fillings are given. It is claimed that the present tomographic system allows fast and accurate imaging of internal body organs and is insensitive to the blurring effects which motion of these organs tends to produce.

Five Roles of an Information System: A Social Constructionist Approach to Analysing the Use of ERP Systems

Directory of Open Access Journals (Sweden)

Linda Askenäs

2003-01-01

Full Text Available This paper presents a novel way of thinking about how information systems are used in organisations. Traditionally, computerised information systems are viewed as objects. In contrast, by viewing the in-formation system as an actor, the understanding of the structuration process increases. The user, being influenced by the ERP (Enterprise Resource Planning system and giving it an actor role, thereby also confers agency on the ERP system; through its very use it influences actions and thus also the structure. Based on a case study of ERP use in an ABB company over a decade, five different roles played by the ERP systems were identified. The ERP systems acted as Bureaucrat, Manipulator, Administrative assistant, Consultant or were dismissed (Dismissed in the sense that intended users chose to avoid using them. These terms are defined in the full text. The purpose of this approach here is not to "animate" the information systems, to give them life or a mind of their own, but rather to make explicit the socially constructed roles conferred on them by users and others who are affected by them. On this basis, it is possible to suggest how the roles can help us open up new areas of exploration concerning the fruitful use of IT.

2006-08-01

Full Text Available Abstract Background Most of the many computer resources used in clinical teaching of dermatology and venereology for medical undergraduates are information-oriented and focus mostly on finding a "correct" multiple-choice alternative or free-text answer. We wanted to create an interactive computer program, which facilitates not only factual recall but also clinical reasoning. Methods Through continuous interaction with students, a new computerised interactive case simulation system, NUDOV, was developed. It is based on authentic cases and contains images of real patients, actors and healthcare providers. The student selects a patient and proposes questions for medical history, examines the skin, and suggests investigations, diagnosis, differential diagnoses and further management. Feedback is given by comparing the user's own suggestions with those of a specialist. In addition, a log file of the student's actions is recorded. The program includes a large number of images, video clips and Internet links. It was evaluated with a student questionnaire and by randomising medical students to conventional teaching (n = 85 or conventional teaching plus NUDOV (n = 31 and comparing the results of the two groups in a final written examination. Results The questionnaire showed that 90% of the NUDOV students stated that the program facilitated their learning to a large/very large extent, and 71% reported that extensive working with authentic computerised cases made it easier to understand and learn about diseases and their management. The layout, user-friendliness and feedback concept were judged as good/very good by 87%, 97%, and 100%, respectively. Log files revealed that the students, in general, worked with each case for 60–90 min. However, the intervention group did not score significantly better than the control group in the written examination. Conclusion We created a computerised case simulation program allowing students to manage patients in a non

2001-11-01

Full Text Available This article reports the findings of the first stage of an ongoing, longitudinal study into the implementation of an interorganisational electronic medical records (EMR system. The study adapted and expanded Davis' (1993 technology acceptance model (TAM to investigate the attitudes of primary care practitioners towards a proposed system for maternity patients. All doctors and midwives holding maternity care contracts with a large urban hospital in New Zealand were sent a questionnaire soliciting their views on a planned EMR system linking the hospital and the primary care sectors. The results showed that whilst Davis' two key factors of perceived ease of use and perceived usefulness were important to medical professionals, another key factor, perceived system acceptability, which concerns control and management of information is vitally important to the acceptance of the system. The study also showed that the two groups of professionals had differing requirements due to different levels of experience and practice computerisation. Finally, the research highlights a number of wider organisational issues particularly relevant to the use of inter organisational systems in general and healthcare systems in particular.

The NRPB automated thermoluminescent dosemeter and dose record keeping system

1975-03-01

This report describes the thermoluminescent personal radiation dosemeter and its associated automated processing equipment, which are being developed by the National Radiological Protection Board, together with the operation of a computerised dosemeter issue and record keeping system. The main justifications for introducing these systems are improvements in the organizational efficiency of the maintenance of individual dose records, a more flexible and accurate dosimetry system, and economics in operational costs. The dosemeter is based on a numbered aluminium plate containing two lithium fluoride in polytetrafluorethylene disks for the measurement of surface and body dose. This dosemeter is wrapped in thin plastic and labelled with the wearer's name and address. On return, the dosemeter is checked automatically for radioactive contamination; it is unwrapped and evaluated; the dose readings are included in the wearer's stored dose record; the dosemeter is annealed and is then available for re-issue to another wearer. Dose reports and warnings are automatically issued to the wearer or his employer. (author)

The OECD Halden Reactor Project is a jointly financed research programme under the auspices of the OECD - Nuclear Energy Agency with fifteen participating countries. One of the main research topics focuses on man-machine systems. Particular attention is paid to the operator's tasks in the reactor control room environment. The overall objective of the research in this field is to provide a basis for improving today's control rooms through the introduction of computer-based solutions for the effective and safe execution of surveillance and control functions in normal as well as off-normal plant situations. The programme comprises four main activities: the verification and validation of safety critical software systems; man-machine interaction research emphasizing improvements in man-machine interfaces on the basis of human factors studies; computerised operator support systems assisting the operator in fault detection/diagnosis and planning of control actions; and control room development providing a basis for retrofitting of existing control rooms and for the design of advanced concepts

Protecting the neck from explosively propelled fragments has traditionally been achieved through a collar attached to the ballistic vest. An Enhanced Protection Under Body Armour Combat Shirt (EP-UBACS) collar has been identified as an additional method of providing neck protection but limited evidence as to its potential medical effectiveness exists to justify its procurement. Entry wound locations and resultant medical outcomes were determined using Abbreviated Injury Scale (AIS) for all fragmentation neck wounds sustained by UK soldiers between 01 January 2010 and 31 December 2011. Data were prospectively entered into a novel computerised tool base and comparisons made between three EP-UBACS neck collar designs in terms of predicted reduction in AIS scores. All collars reduced AIS scores, with the greatest reduction provided by designs incorporating increased standoff from the neck and an additional semi-circle of ballistic material underneath the collar at the front and back. This technique confirms that reinforcing the neck collar of an EP-UBACS would be expected to reduce injury severity from neck wounds. However, without knowledge of entry wound locations for injuries to other body areas as well as the use of AIS scores without clinical or pathological verification its further use in the future may be limited. The ability to overlay any armour design onto a standardised human was potentially the most useful part of this tool and we would recommend developing this technique using underlying anatomical structures and not just the skin surface.

Weiss, W.; Leeb, H.

1993-01-01

IMIS is being set up as part of the German Government's National Response Plan for dealing with the consequences of a large scale radioactive contamination of the environment. The IMIS system has three operational action levels. Level 3 covers the collection of radiological data from state-of-the-art monitoring networks and measurement laboratories. Level 2 involves computerised data processing and quality control, based on standardised procedures for the collection and presentation of measurements. This level also includes the use of transport and dose assessment models. Level 1 includes evaluation of the data, management of the consequences of a given situation, legal enforcement of protective measures and provision of information to the public. In its final form the IMIS system will consist of a total of 75 RISC computers linked together by an efficient packet-switched Wide Area Network. Owing to various demands of the individual users, three different types of RISC computers are used. The system software includes ULTRIX, TCP/IP and X windows. The relational database management system ORACLE is used together with the query language SQL-Plus. Statistical analyses are carried out with the standard product SAS. The geographical information system TERRA provides all the tools necessary for a detailed geographic presentation of the data. (author)

Full Text Available Abstract Background Computerised cognitive behaviour therapy (cCBT involves standardised, automated, interactive self-help programmes delivered via a computer. Randomised controlled trials (RCTs and observational studies have shown than cCBT reduces depressive symptoms as much as face-to-face therapy and more than waiting lists or treatment as usual. cCBT’s efficacy and acceptability may be influenced by the “human” support offered as an adjunct to it, which can vary in duration and can be offered by people with different levels of training and expertise. Methods/design This is a two-by-two factorial RCT investigating the effectiveness, cost-effectiveness and acceptability of cCBT supplemented with 12 weekly phone support sessions are either brief (5–10 min or extended (20–30 min and are offered by either an expert clinician or an assistant with no clinical training. Adults with non-suicidal depression in primary care can self-refer into the study by completing and posting to the research team a standardised questionnaire. Following an assessment interview, eligible referrals have access to an 8-session cCBT programme called Beating the Blues and are randomised to one of four types of support: brief-assistant, extended-assistant, brief-clinician or extended-clinician. A sample size of 35 per group (total 140 is sufficient to detect a moderate effect size with 90% power on our primary outcome measure (Work and Social Adjustment Scale; assuming a 30% attrition rate, 200 patients will be randomised. Secondary outcome measures include the Beck Depression and Anxiety Inventories and the PHQ-9 and GAD-7. Data on clinical outcomes, treatment usage and patient experiences are collected in three ways: by post via self-report questionnaires at week 0 (randomisation and at weeks 12 and 24 post-randomisation; electronically by the cCBT system every time patients log-in; by phone during assessments, support sessions and exit interviews.

Randomised controlled trials (RCTs) and observational studies have shown than cCBT reduces depressive symptoms as much as face-to-face therapy and more than waiting lists or treatment as usual. cCBT's efficacy and acceptability may be influenced by the "human" support offered as an adjunct to it, which can vary in duration and can be offered by people with different levels of training and expertise. This is a two-by-two factorial RCT investigating the effectiveness, cost-effectiveness and acceptability of cCBT supplemented with 12 weekly phone support sessions are either brief (5-10 min) or extended (20-30 min) and are offered by either an expert clinician or an assistant with no clinical training. Adults with non-suicidal depression in primary care can self-refer into the study by completing and posting to the research team a standardised questionnaire. Following an assessment interview, eligible referrals have access to an 8-session cCBT programme called Beating the Blues and are randomised to one of four types of support: brief-assistant, extended-assistant, brief-clinician or extended-clinician.A sample size of 35 per group (total 140) is sufficient to detect a moderate effect size with 90% power on our primary outcome measure (Work and Social Adjustment Scale); assuming a 30% attrition rate, 200 patients will be randomised. Secondary outcome measures include the Beck Depression and Anxiety Inventories and the PHQ-9 and GAD-7. Data on clinical outcomes, treatment usage and patient experiences are collected in three ways: by post via self-report questionnaires at week 0 (randomisation) and at weeks 12 and 24 post-randomisation; electronically by the cCBT system every time patients log-in; by phone during assessments, support sessions and exit interviews. The study's factorial design increases its efficiency by allowing the

Full Text Available Abstract Background People with multiple sclerosis (MS are at high risk of depression. We undertook a pilot trial of computerised cognitive behavioural therapy (CCBT for the treatment of depression in people with MS to test the feasibility of undertaking a full trial. Methods Participants with a diagnosis of MS and clinical levels of depression were recruited through out-patient clinics and postal screening questionnaires at two UK centres and randomised to CCBT or usual care. Clinical outcomes included the Beck Depression Inventory (BDI-II and Multiple Sclerosis Impact Scale (MSIS-29 at baseline, 8 and 21 weeks. Feasibility outcomes included: recruitment rate; reasons for refusal, withdrawal and dropout; feasibility and acceptability of the proposed outcome measures; sample size estimation and variation in and preferences for service delivery. Results Twenty-four participants were recruited. The recruitment rate, calculated as the proportion of those invited to fill in a screening questionnaire who were consented into the trial, was 4.1%. Recruitment through out-patient clinics was somewhat slower than through screening questionnaire mail-out but the overall recruitment yield was similar. Of the 12 patients in the CCBT arm, 9 (75% completed at least four, and 6 completed all 8 CCBT sessions. For completers, the median time (IQR to complete all eight CCBT sessions was 15 (13 to 20 weeks. Participants expressed concern about the face validity of the Beck Depression Inventory II for the measurement of self-reported depression in people with MS. The MSIS-29 was the patient-reported outcome measure which participants felt best reflected their concerns. The estimated sample size for a full trial is between 180 and 390 participants. NHS partners were not delivering CCBT in community facilities and participants preferred to access CCBT at home, with no one expressing a preference for use of CCBT in an alternative location. Conclusions A definitive

Full text: In early 1999s the SNSA started to develop a computerised registration system of occupational radiation exposure for workers in a nuclear fuel cycle in Slovenia, which arises from four nuclear facilities: nuclear power plant, research reactor, storage facility and uranium mine. In the period 1985-2000 about 5000 workers altogether were monitored due to exposure in a nuclear fuel cycle in Slovenia (about 1200 employees and 3800 outside workers), with an average of 1000 workers being assessed each calendar year. Four dosimetric services regularly perform personal monitoring of the occupational exposure and all of them have been requested to provide data to the SNSA electronically. The computerised register was put into operation in 2000 enabling prompt control of personal exposures, including annual, 5-year and lifetime doses. Besides individual exposure also collective doses can be evaluated, together with size and time distributions and trends over certain periods. Apart from the total dose, the doses received due to external radiation (gamma, neutrons) and due to internal radiation have been separately recorded into the register. In addition, personal data of workers as well as employee and facility data have been also recorded. Some statistics of dose distributions have been evaluated and the results have been compared to international data. More than 80% of workers from the register have been exposed in the NPP. Workers received the major part of their exposure during the annual outage works. It is found out that in recent years, the average individual and collective doses have shown a rising trend.

Strategic energy planning: Modelling and simulating energy market behaviours using system thinking and systems dynamics principles

International Nuclear Information System (INIS)

Papageorgiou, George Nathaniel

2005-01-01

In the face of limited energy reserves and the global warming phenomenon, Europe is undergoing a transition from rapidly depleting fossil fuels to renewable unconventional energy sources. During this transition period, energy shortfalls will occur and energy prices will be increasing in an oscillating manner. As a result of the turbulence and dynamicity that will accompany the transition period, energy analysts need new appropriate methods, techniques and tools in order to develop forecasts for the behaviour of energy markets, which would assist in the long term strategic energy planning and policy analysis. This paper reviews energy market behaviour as related to policy formation, and from a dynamic point of view through the use of ''systems thinking'' and ''system dynamics'' principles, provides a framework for modelling the energy production and consumption process in relation to their environment. Thereby, effective energy planning can be developed via computerised simulation using policy experimentation. In a demonstration model depicted in this paper, it is shown that disasters due to attractive policies can be avoided by using simple computer simulation. (Author)

Designing healthcare information technology to catalyse change in clinical care

Directory of Open Access Journals (Sweden)

William Lester

2008-05-01

Full Text Available The gap between best practice and actual patient care continues to be a pervasive problem in our healthcare system. Efforts to improve on this knowledge_performance gap have included computerised disease management programs designed to improve guideline adherence. However, current computerised reminder and decision support interventions directed at changing physician behaviour have had only a limited and variable effect on clinical outcomes. Further, immediate pay-for-performance financial pressures on institutions have created an environmentwhere disease management systems are often created under duress, appended to existing clinical systems and poorly integrated into the existing workflow, potentially limiting their realworld effectiveness. The authors present a review of disease management as well as a conceptual framework to guide the development of more effective health information technology (HIT tools for translating clinical information into clinical action.

The invention relates to cardiac imaging systems and methods employing computerised tomographic scanning. Apparatus is described which allows an image of the radiation attenuation of the heart at a desired phase of the cardiac cycle. The patients ECG signal can be used in a transverse-and-rotate type CT scanner as a time base, so that the beam reaches the heart at a desired phase of the cardiac cycle, or, in a purely rotational-type CT scanner continuously generated scan data is only stored for corresponding phases of successive cardiac cycles. Alternatively, gating of the beams themselves by shuttering or switching the power supply can be controlled by the ECG signal. A pacemaker is used to stabilize the cardiac period. Also used is a system for recognising unacceptable variations in the cardiac period and discarding corresponding scan data. In a transverse-and-rotate type fan-beam CT scanner, the effective beam width is narrowed to reduce the duration of the traverse of the heart. (U.K.)

The 500 MWe PHWR has two totally independent, diverse, fast acting shutdown system called Shutdown System 1 (SDS 1) and Shutdown System 2 (SDS 2). The trip generation circuitry of SDS 1 and SDS 2 are known as Reactor Protection System 1 (RPS 1) and Reactor Protection System 2 (RPS 2) respectively. Some of the features specific to 500 MWe reactors are Core Over Power Protection System (COPPS) based upon in core Self Powered Neutron Detector (SPND) signals, use of local two out of three coincidence logic and adoption of overlap testing for RPS 2, use of Fine Impulse Testing (FIT) in RPS 2, testing of the final control elements namely electro-magnetic clutch of individual Shutoff Rods (SRs) of SDS 1 and all the fast acting valves of SDS 2, etc. The two shutdown systems have totally separate sets of sensors and associated signal processing circuitry as well as physical arrangements. A separate computerised test and monitoring unit is used for each of the two shutdown systems. Use of Programmable Digital Comparator (PDC) unit exclusively for reactor protection systems, has been adopted. The capability of PDC unit is enhanced and communication links are provided for its integration in over all system. The paper describes the design features of reactor protection systems.

A Computerised Business Ethics Expert System -A new approach to improving the ethical quality of business decision-making

Directory of Open Access Journals (Sweden)

Bernie Brenner

2007-06-01

Full Text Available Abstract Where unethical business decision-making arises from failures of ethical perception, there is an important role for ethical training and decision-making tools. These may help business people to consider all relevant issues when assessing the ethical status of potential decisions. Ethical training programmes give business people a basic understanding of the principles which underlie ethical judgements and equip them with many of the necessary skills for dealing with the ethical dilemmas which they face in their jobs. Similarly, ethical decision-making tools may guide managers through the various ethical considerations which are relevant to business decision-making and help them to develop their ethical-perceptual skills. Furthermore, by establishing and reinforcing good ethical decision-making practices, training programmes and decision-making tools may also reduce the incidence of self-consciously unethical decision-making. A new approach to improving the ethical quality of business decision-making by the use of computerized business ethics expert systems is proposed. These systems have the potential to guide business people through a process of ethical evaluation while simultaneously fulfilling an educational role, thus providing many of the benefits of both training programmes and decision-making tools. While the prospect of a computer system which could simply make ethical judgements for business people is both unrealistic and undesirable, a system which leads human decision-makers through a structured assessment process has the potential for genuine benefits.

2009-03-01

In recent years, the theory that on-line clinical decision support systems can improve patients' safety among hospitalised individuals has gained greater acceptance. However, the feasibility of implementing such a system in a middle or low-income country has rarely been studied. Understanding the current prescription process and a proper needs assessment of prescribers can act as the key to successful implementation. The aim of this study was to explore physicians' opinions on the current prescription process, and the expected benefits and perceived obstacles to employ Computerised Physician Order Entry in an Iranian teaching hospital. Initially, the interview guideline was developed through focus group discussions with eight experts. Then semi-structured interviews were held with 19 prescribers. After verbatim transcription, inductive thematic analysis was performed on empirical data. Forty hours of on-looker observations were performed in different wards to explore the current prescription process. The current prescription process was identified as a physician-centred, top-down, model, where prescribers were found to mostly rely on their memories as well as being overconfident. Some errors may occur during different paper-based registrations, transcriptions and transfers. Physician opinions on Computerised Physician Order Entry were categorised into expected benefits and perceived obstacles. Confidentiality issues, reduction of medication errors and educational benefits were identified as three themes in the expected benefits category. High cost, social and cultural barriers, data entry time and problems with technical support emerged as four themes in the perceived obstacles category. The current prescription process has a high possibility of medication errors. Although there are different barriers confronting the implementation and continuation of Computerised Physician Order Entry in Iranian hospitals, physicians have a willingness to use them if these systems

A decision support system and rule-based algorithm to augment the human interpretation of the 12-lead electrocardiogram.

Science.gov (United States)

Cairns, Andrew W; Bond, Raymond R; Finlay, Dewar D; Guldenring, Daniel; Badilini, Fabio; Libretti, Guido; Peace, Aaron J; Leslie, Stephen J

The 12-lead Electrocardiogram (ECG) has been used to detect cardiac abnormalities in the same format for more than 70years. However, due to the complex nature of 12-lead ECG interpretation, there is a significant cognitive workload required from the interpreter. This complexity in ECG interpretation often leads to errors in diagnosis and subsequent treatment. We have previously reported on the development of an ECG interpretation support system designed to augment the human interpretation process. This computerised decision support system has been named 'Interactive Progressive based Interpretation' (IPI). In this study, a decision support algorithm was built into the IPI system to suggest potential diagnoses based on the interpreter's annotations of the 12-lead ECG. We hypothesise semi-automatic interpretation using a digital assistant can be an optimal man-machine model for ECG interpretation. To improve interpretation accuracy and reduce missed co-abnormalities. The Differential Diagnoses Algorithm (DDA) was developed using web technologies where diagnostic ECG criteria are defined in an open storage format, Javascript Object Notation (JSON), which is queried using a rule-based reasoning algorithm to suggest diagnoses. To test our hypothesis, a counterbalanced trial was designed where subjects interpreted ECGs using the conventional approach and using the IPI+DDA approach. A total of 375 interpretations were collected. The IPI+DDA approach was shown to improve diagnostic accuracy by 8.7% (although not statistically significant, p-value=0.1852), the IPI+DDA suggested the correct interpretation more often than the human interpreter in 7/10 cases (varying statistical significance). Human interpretation accuracy increased to 70% when seven suggestions were generated. Although results were not found to be statistically significant, we found; 1) our decision support tool increased the number of correct interpretations, 2) the DDA algorithm suggested the correct

An alternative colour system has been developed for the EMI scanner incorporating a sixteen colour table with a selection of scale manipulation facilities. Features such as colour deletion and colour of interest pulsation are included and the output is available both in RGB (red, green, blue) form and PAL (phase alteration line by line) coded composite video form (625 line interlaced) to facilitate the use of a domestic television receiver. A digital processing unit, implemented in SSI (small scale integration) and MSI (medium scale integration) logic, is interfaced to the independent viewing centre frame buffer memory. The unit is housed in a 19 inch cabinet on five standard Eurocards with three modular power supplies. The front panel provides a selection of switch options effecting instantaneous changes in the display. Digital information is processed in real time so that normal window and level variations are tracked by the colour display. The cost of the complete system was about Pound1800 and of this, Pound1000 was absorbed in the selection of a high quality RGB monitor (Sony PVM1300E). (author)

Orchard, John; Rae, Katherine; Brooks, John; Hägglund, Martin; Til, Lluis; Wales, David; Wood, Tim

2010-01-01

The Orchard Sports Injury Classification System (OSICS) is one of the world’s most commonly used systems for coding injury diagnoses in sports injury surveillance systems. Its major strengths are that it has wide usage, has codes specific to sports medicine and that it is free to use. Literature searches and stakeholder consultations were made to assess the uptake of OSICS and to develop new versions. OSICS was commonly used in the sports of football (soccer), Australian football, rugby union, cricket and tennis. It is referenced in international papers in three sports and used in four commercially available computerised injury management systems. Suggested injury categories for the major sports are presented. New versions OSICS 9 (three digit codes) and OSICS 10.1 (four digit codes) are presented. OSICS is a potentially helpful component of a comprehensive sports injury surveillance system, but many other components are required. Choices made in developing these components should ideally be agreed upon by groups of researchers in consensus statements. PMID:24198559

1988-01-01

This paper reports on the use of operator surveys and trip report analysis methods which the Central Electricity Generating Board has developed to assess the extent and adequacy of operator support systems currently installed on its four twin-reactor, first generation Advanced Gas Cooled Reactor nuclear power plants. The survey consisted of a programme of structured interviews with control room engineers. The scope of the questions addressed; working environment, communications, man-machine interface, procedural information, and the diagnostic and predictive support system. The analysis of trip reports was targetted at identifying aspects of the performance of the operator support systems which might have been contributory to the cause of reactor trip. The results of this work are being used to assist in determining guidelines for the development of operator support systems, computerised controls and the structure of station operating procedures

A 20-year-old girl presented with headache, projectile vomiting, unsteadiness of gait and urgency of micturition. She had left seventh nerve upper motor neuron type paresis, increased tone in all four limbs, exaggerated deep tendon reflexes, cerebellar signs, and papilloedema. Cerebrospinal fluid showed lymphocytosis with elevated protein and normal glucose level. Cerebral computerised tomographic scan and MRI showed bilateral diffuse asymmetric supra- and infra-tentorial lesions (predominantly in the supratentorial and left cerebrum. On MRI, the lesions were hyperintense on T2, and proton density-weighted images and hypointense on T1-weighted images. Based on the clinical findings of raised intracranial tension and MRI features, initial diagnoses of gliomatosis cerebrii, tuberculous meningitis, primary central nervous system lymphoma and chronic viral encephalitis were considered. PACNS was not included in the initial differentials and, an open brain biopsy was advised which established the definitive diagnosis.

A computerised record was used to collect data following an anesthesiological check-up of pregnant women at approximately 30 weeks of pregnancy. The record was input onto a portable PC in the anesthesia outpatient clinic, memorized on disk (3.5") and then transferred onto a PC network (one PC for each operating theatre) for "real time" consultation of each patient's data. All pregnant women attending the antenatal clinico were also given a folder illustrating epidural anesthetic techniques. Seven hundred and nine outpatient visits have been performed over the past two years with a 62% utilisation ratio. The collection of data using a computerised system allows a rapid and efficacious system of communication to be set up among the membranes of the anesthesiological team, thus encouraging the use of epidural techniques during labour. The distribution of the folder also facilitated the task of the anesthetist who found that pregnant women visiting the anesthesia clinic were already familiar with the epidural technique.

X-ray body scanner for computerised tomography

International Nuclear Information System (INIS)

1977-01-01

An X-ray source is described whose source is collimated into a thin fan-shaped beam. The detector means is spaced from the sources and both are mounted for scanning and orbiting jointly about a body in a partial or complete resolution. The X-ray intensities thus obtained provide data for reconstructing an image. The detector and source combination and the body are moved relative to one another in an axial direction to enable scanning of the body layers in sequence. In one embodiment the X-ray source is pulsed as it scans, and in another the fan-shaped beam is on continuously and readout is done sequentially. Thus in either case a large number of intensities for each layer are obtained. A high precision encoder system is used to synchronize X-ray pulses and readouts spatially and with line frequency. Means are provided for storing the cables leading to the rotatable source, the detectors and other moveable components. An embodiment for scanning a body part such as a breast has means for conditioning and controlling the water in which the part is immersed. (C.F.)

Goal-oriented failure analysis - a systems analysis approach to hazard identification

International Nuclear Information System (INIS)

Reeves, A.B.; Davies, J.; Foster, J.; Wells, G.L.

1990-01-01

Goal-Oriented Failure Analysis, GOFA, is a methodology which is being developed to identify and analyse the potential failure modes of a hazardous plant or process. The technique will adopt a structured top-down approach, with a particular failure goal being systematically analysed. A systems analysis approach is used, with the analysis being organised around a systems diagram of the plant or process under study. GOFA will also use checklists to supplement the analysis -these checklists will be prepared in advance of a group session and will help to guide the analysis and avoid unnecessary time being spent on identifying obvious failure modes or failing to identify certain hazards or failures. GOFA is being developed with the aim of providing a hazard identification methodology which is more efficient and stimulating than the conventional approach to HAZOP. The top-down approach should ensure that the analysis is more focused and the use of a systems diagram will help to pull the analysis together at an early stage whilst also helping to structure the sessions in a more stimulating way than the conventional techniques. GOFA will be, essentially, an extension of the HAZOP methodology. GOFA is currently being computerised using a knowledge-based systems approach for implementation. The Goldworks II expert systems development tool is being used. (author)

Computerised tomography cannot be of great help in diagnosing meningitis. Examination of the cerebrospinal fluid remains essential. After the inflammation of the meninges has progressed to some stage of encephalitis, the formation of an abscess can be located via computed tomography. It is characterised by the ring-type abscess capsule. Computed tomography for diagnostic purposes is superior to cerebral scanning, which demonstrates enhanced activity, but does not show the formation of a membrane, so essential for differential diagnosis. Furthermore, computed tomography shows the adjacent anatomical structures and answers the questions of displacements and threatening invasion of the ventricle system. Epidural and subdural abscesses can also be located by computed tomography. Therapy can begin directly after computerised tomography, whereas in scintigraphy only a non-specific enhanced activity is present, which often does not allow differentiation between epidural and subdural location.

Dheeba, J.; Jaya, T.; Singh, N. Albert

2017-09-01

Classification of cancerous masses is a challenging task in many computerised detection systems. Cancerous masses are difficult to detect because these masses are obscured and subtle in mammograms. This paper investigates an intelligent classifier - fuzzy support vector machine (FSVM) applied to classify the tissues containing masses on mammograms for breast cancer diagnosis. The algorithm utilises texture features extracted using Laws texture energy measures and a FSVM to classify the suspicious masses. The new FSVM treats every feature as both normal and abnormal samples, but with different membership. By this way, the new FSVM have more generalisation ability to classify the masses in mammograms. The classifier analysed 219 clinical mammograms collected from breast cancer screening laboratory. The tests made on the real clinical mammograms shows that the proposed detection system has better discriminating power than the conventional support vector machine. With the best combination of FSVM and Laws texture features, the area under the Receiver operating characteristic curve reached .95, which corresponds to a sensitivity of 93.27% with a specificity of 87.17%. The results suggest that detecting masses using FSVM contribute to computer-aided detection of breast cancer and as a decision support system for radiologists.

Computerised Genetic Risk Assessment and Decision Support in Primary Care

Directory of Open Access Journals (Sweden)

Andrew Coulson

2000-09-01

To address these issues, a new computer application called RAGs (Risk Assessment in Genetics has been designed. The system allows a doctor to create family trees and assess genetic risk of breast cancer. RAGs possesses two features that distinguish it from similar software: (a a user-centred design, which takes into account the requirements of the doctor-patient encounter; (b risk reporting using qualitative evidence for or against an increased risk, which the authors believe to be more useful and accessible than numerical probabilities are. In that the system allows for any genetic risk guideline to be implemented, it can be used with all diseases for which evaluation guidelines exist. The software may be easily modified to cater for the amount of detail required by different specialists.

Prevention is an essential aspect in paediatric poisonings, especially when recurrent episodes are detected. The aims of this article are to detect the recurrence rate for suspected poisoning in emergency consultations, as well as to identify the cases in which specific preventive measures are indicated, and to determine whether the creation of a specific item for recurrent episodes in the computerised medical records system facilitates its detection. A retrospective study was conducted on patients less than 18 years of age treated in the emergency room due to suspected poisoning during 2013 and 2014. Patients were divided according to the presence or absence of previous episodes. From January 2014, a specific item is present in the computerised medical records of the poisoned patient, where the history of previous episodes is registered. The preventive measures used between both groups were compared. A total of 731 consultations were recorded for suspected poisoning. A history of previous episodes was detected in 9% of cases. Medical injury reports and follow-up in outpatient clinics were more often performed in patients with recurrent episodes than in patients without them (28.8% vs 18.0%, P=.034, and 65.2% vs. 18.8%, P<.001, respectively). In 2013, the recurrence rate was 5.9% vs 12% in 2014 (P=.004). The recurrence rate observed is significant. Although preventive measures are more frequently indicated in these patients, their application is low. The creation of a specific item for recurrent episodes in a computerised medical records system facilitates their detection. Copyright © 2016 Asociación Española de Pediatría.

2004-04-01

The objective of the function-oriented displays and alarm project is to design, implement and evaluate Human System Interfaces (HSI) based on a function-oriented design philosophy. Function-oriented design is an approach for designing HSIs where the plant's functions, identified through a function analysis, are used for determining the content, organisation, and management of displays. The project has used the 'FITNESS approach', originally developed by EDF in France, as a starting point. FITNESS provides an integrated display system consisting of process operating displays, operating procedures, alarms and trend displays - all based on a functional decomposition of the plant. So far, two prototypes have been implemented on the FRESH PWR simulator in HAMMLAB. The first prototype focused on the condensate pumps. Three process operating displays representing functions at different levels of the functional hierarchy were implemented. Computerised startup and shutdown procedures for the condensate pumps function were also implemented. In the second prototype, the scope was increased to cover the main feedwater system. The displays of the first prototype were redesigned and additional displays were created. In conclusion, the first phase of the project has been completed successfully, and we are now ready to enter the second phase. In the second phase, the scope of the prototype will be increased further to include the steam-generators and function-oriented disturbance operating procedures. The prototype will be evaluated in a user test conducted later in 2004. (Author)

Full Text Available Despite the large number of instruments developed to assess the more purely cognitive executive functions in Brazilian children, few studies have developed instruments for the assessment of the most motivational components of these functions. The primary aim of this study was to develop a computerised version of the Children's Gambling Task (CGT to assess affective decision-making in preschoolers. The present study also aimed to investigate whether this version of the task is sensitive to developmental changes across the preschool period and to examine gender differences in decision-making. We administered the CGT and the Columbia Mental Maturity Scale (CMMS to 137 Brazilian children between the ages of three and five years old. Age differences between three-and four-year-olds, but not between four-and five-year-olds were found. Gender differences were not found. From this preliminary study, the computerised version of the CGT for Brazilian child population proved to be suitable for Brazilian child population.Apesar do grande número de instrumentos desenvolvidos para avaliação das funções executivas mais puramente cognitivas em crianças brasileiras, há poucos estudos que desenvolveram medidas para avaliação dos componentes mais motivacionais dessas funções.

Information and communication technology (ICT) use in child and family nursing: what do we know and where to now?

Science.gov (United States)

Ridgway, Lael; Mitchell, Creina; Sheean, Frances

2011-12-01

Whilst the use of information and communication technology (ICT) in acute care services has been well documented, less is known about the impact of computerising community-based primary care such as child and family health nursing services. This self-complete survey of 606 nurses working in the Victorian Maternal and Child Health (MCH) service (response rate 60%) found that the predominantly older workforce were confident with the use of ICT. This contrasts with findings from the acute sector where older nurses had lower ICT confidence. The survey revealed a variation in ICT support and a lack of data collection system compatibility. Professional education resources were not able to be effectively used in all locally supplied computers. Although MCH nurses have adapted well to computerisation, there is room for improvement. Appropriate resourcing, education and infrastructure support are areas that need to be addressed and would benefit from an overarching body responsible for development and quality assurance.

2007-06-01

Automatic speech recognition (ASR) can provide a rapid means of controlling electronic assistive technology. Off-the-shelf ASR systems function poorly for users with severe dysarthria because of the increased variability of their articulations. We have developed a limited vocabulary speaker dependent speech recognition application which has greater tolerance to variability of speech, coupled with a computerised training package which assists dysarthric speakers to improve the consistency of their vocalisations and provides more data for recogniser training. These applications, and their implementation as the interface for a speech-controlled environmental control system (ECS), are described. The results of field trials to evaluate the training program and the speech-controlled ECS are presented. The user-training phase increased the recognition rate from 88.5% to 95.4% (p<0.001). Recognition rates were good for people with even the most severe dysarthria in everyday usage in the home (mean word recognition rate 86.9%). Speech-controlled ECS were less accurate (mean task completion accuracy 78.6% versus 94.8%) but were faster to use than switch-scanning systems, even taking into account the need to repeat unsuccessful operations (mean task completion time 7.7s versus 16.9s, p<0.001). It is concluded that a speech-controlled ECS is a viable alternative to switch-scanning systems for some people with severe dysarthria and would lead, in many cases, to more efficient control of the home.

Limitations of Managing Safety by Numbers

International Nuclear Information System (INIS)

Engström, D.

2016-01-01

Work, especially in a complex, dynamic workplaces, often requires subtle, local judgment with regard to timing of subtasks, relevance, importance, prioritization, etc. Still, people in the nuclear industry seem to think safety results from error counts and people just following procedures. In the wake of failure it can be tempting to introduce new procedures and an even stricter “rule following culture”. None, or at least very little, attention is given to tacit knowledge and individual skills. I am aiming to highlight the inadequacy of putting too much trust in formalization and that reporting and trending of events will contribute to increased learning, an increased nuclear safety and an efficient operational experience. The ability to interpret a situation concrete depends on proven experience in similar situations, analogical thinking and tacit knowledge. I intend to problematize the introduction and use of so-called Corrective Action Program (CAP) and computerised reporting systems linked to CAP in the nuclear industry. Categorization and trending in computerised reporting systems is only based on the direct or triggering cause and not based on any analyzes, so the question we have to ask is what the trends are really telling us, if anything at all.

Application of Geographic Information System (GIS) in Drug Logistics Management Information System (LMIS) at District Level in Malawi: Opportunities and Challenges

Science.gov (United States)

Chikumba, Patrick Albert

District pharmacies in Malawi use a computerised IS to monitor the flow of products from a warehouse to health service delivery points and determine understocked or overstocked products at each health facility. Currently, all drug LMIS reports are in tabular forms. The GIS can help health and drug logistics officers to get additional spatial information, such as locations of health facilities and environmental factors, to the existing reports in the form of maps. This paper highlights some opportunities and challenges of applying the GIS in the drug LMIS, which basically involve technologies, organisation, and standards and data integration. It has been found that this idea is very good but it requires much effort, commitment and resources for successful implementation.

Computerised tomography in radiotherapy planning

International Nuclear Information System (INIS)

Badcock, P.C.

1983-01-01

This study evaluates the effectiveness of computed tomography as an adjunct to radiotherapy planning. Until recently, acquisition of accurate data concerning tumour anatomy lagged behind other developments in radiotherapy. With the advent of computer-tomography (CT), these data can be displayed and transmitted to a treatment planning computer. It is concluded that the greatest inaccuracies in the radiation treatment of patients are to be found in both the inadequate delineation of the target volume within the patient and changes in body outline relative to the target volume over the length of the irradiated volume. The technique was useful in various subgroups (pelvic, intra-thoracic and chest-wall tumours) and for those patients being treated palliatively. With an estimated improvement in cure rate of 4.5% and cost-effective factors of between 3.3 and 5, CT-assisted radiotherapy planning appears to be a worthwhile procedure. (orig.)

Since 2005 the National Residue & Contaminants Control Plan (NRCCP) in Brazil has been considerably enhanced, increasing the number of samples, substances and species monitored, and also the analytical detection capability. The Brazilian laboratory network was forced to improve its quality standards in order to comply with the NRCP's own evolution. Many aspects such as the limits of quantification (LOQs), the quality management systems within the laboratories and appropriate method validation are in continuous improvement, generating new scenarios and demands. Thus, efficient management mechanisms for monitoring network performance and its adherence to the established goals and guidelines are required. Performance indicators associated to computerised information systems arise as a powerful tool to monitor the laboratories' activity, making use of different parameters to describe this activity on a day-to-day basis. One of these parameters is related to turnaround times, and this factor is highly affected by the way each laboratory organises its management system, as well as the regulatory requirements. In this paper a global view is presented of the turnaround times related to the type of analysis, laboratory, number of samples per year, type of matrix, country region and period of the year, all these data being collected from a computerised system called SISRES. This information gives a solid background to management measures aiming at the improvement of the service offered by the laboratory network.

Sepsis is a leading cause of mortality and morbidity in hospitalised patients. The Centers for Medicare and Medicaid Services (CMS) mandated that US hospitals report sepsis bundle compliance rate as a quality process measure in October 2015. The specific aim of our study was to improve the CMS sepsis bundle compliance rate from 30% to 40% across 20 acute care hospitals in our healthcare system within 1 year. The study included all adult inpatients with sepsis sampled according to CMS specifications from October 2015 to September 2016. The CMS sepsis bundle compliance rate was tracked monthly using statistical process control charting. A baseline rate of 28.5% with 99% control limits was established. We implemented multiple interventions including computerised decision support systems (CDSSs) to increase compliance with the most commonly missing bundle elements. Compliance reached 42% (99% statistical process control limits 18.4%-38.6%) as CDSS was implemented system-wide, but this improvement was not sustained after CMS changed specifications of the outcome measure. Difficulties encountered elucidate shortcomings of our study methodology and of the CMS sepsis bundle compliance rate as a quality process measure.

Full Text Available Major depression is a highly prevalent psychopathology with high relapse rates. Following remission from a depressive episode, neurocognitive difficulties in attention, working memory and executive function often persist, preventing full clinical recovery. These neurocognitive deficits are often present since the first depressive episode and have been shown to predict relapse. The efficacy of computerised neurocognitive remediation therapy (NCRT to improve attention, memory and executive function has been demonstrated in several clinical populations but randomised controlled trials (RCT have not been conducted in depression. The present study aimed to conduct a pilot, randomised study, of computerised NCRT for individuals with past depression, currently in remission. Twenty two individuals remitted from depression were randomly assigned to receive 20 one-hour sessions over 5 week of ether computerised NCRT or a component-equivalent allocation (play online computer games. The NCRT group showed significantly larger improvements in performance relative to the Games group in the three targeted neurocognitive domains: divided attention, verbal working memory, and planning, but also in non-targeted domains of long-term verbal memory and switching abilities. No significant effect was observed in the NCRT-targeted domain visual working memory. These preliminary results suggest computerised NCRT efficacy to improve targeted neurocognitive processes during depression remission and support its potential value as preventative connected intervention tool.

The Mediation Information System Engineering project is currently finishing its second iteration (MISE 2.0). The main objective of this scientific project is to provide any emerging collaborative situation with methods and tools to deploy a Mediation Information System (MIS). MISE 2.0 aims at defining and designing a service-based platform, dedicated to initiating and supporting the interoperability of collaborative situations among potential partners. This MISE 2.0 platform implements a model-driven engineering approach to the design of a service-oriented MIS dedicated to supporting the collaborative situation. This approach is structured in three layers, each providing their own key innovative points: (i) the gathering of individual and collaborative knowledge to provide appropriate collaborative business behaviour (key point: knowledge management, including semantics, exploitation and capitalisation), (ii) deployment of a mediation information system able to computerise the previously deduced collaborative processes (key point: the automatic generation of collaborative workflows, including connection with existing devices or services) (iii) the management of the agility of the obtained collaborative network of organisations (key point: supervision of collaborative situations and relevant exploitation of the gathered data). MISE covers business issues (through BPM), technical issues (through an SOA) and agility issues of collaborative situations (through EDA).

Full Text Available Small businesses face many problems if they are to survive the first five years of operation. The increasing complexity of information needed to run a business in the 21st Century has added another obstacle to what is already a tough course. Sooner or later, survivors are faced with the prospect of investing in computer based information systems (CBIS. Properly handled, the investment will improve the competitiveness of the company. Badly handled, the investment will handicap the company and perhaps even lead to its closure. Using survey methodology, the present study collected information from 171 small businesses that had purchased computer systems with a view to finding out what factors contribute to successful implementation of CBIS. The variables studied included background characteristics of the organization, background characteristics of the Chief Executive Officer, decision making processes, and a range of variables relating to the performance of the system itself. The outcome variable was user satisfaction. We developed and tested a CBIS implementation success model based on these variables. Results showed that although the performance of the system was the immediate determinant of satisfaction, the background variables had both direct and indirect (mediated effects on satisfaction. These findings emphasise the importance of going beyond the immediate surrounds of a computing environment if one wishes to explain the factors that influence CBIS success in small businesses.

1999-12-31

In a recently completed European collaborative project, the aim was to address the issue of boiler tube failures and thereby plant availability. The reduction of forced outages due to component failures and the reduction of planned outages for preventative maintenance can both contribute in this respect. It has been possible to assess tube degradation due to erosion, corrosion and overheating through the use of on-line techniques (thin layer activation, corrosion probes and novel temperature sensors) and off-line techniques (cold air velocity measurements, laser shearography and measurements of steam side oxide) which have been developed in the project. These techniques have been demonstrated on an oil fired boiler in Portugal and a coal fired unit in Spain. The output from the monitoring techniques has been integrated in the AMASS maintenance advisory and surveillance system. This is a computerised system comprising a spatial database with add-on tools designed to assess data from individual monitors and to provide the user with information on tube life utilisation rates and the probability of tube failure occurring. A description of the monitoring techniques will be described along with some of the results of demonstrating them in the field. Also an overview of the computerized system and the way in which it works will be given along with examples of how it can be used to assist with preventative maintenance and to help avoid unplanned outages.

On line performance monitoring for predictive maintenance [Paper No.: VIA - 2

International Nuclear Information System (INIS)

Gupta, R.K.; Chandra, Rajesh

1981-01-01

There will always be progressive deterioration in the performance of dynamic equipment due to normal inevitable wear, malfunctions, failures and other reasons. In most cases it is possible to monitor some parameters of a system which would get progressively affected with the deterioration in the health of the system. By on-line monitoring of such predetermined parameters, compared with preset base data generated for a healthy system earlier, would prove very helpful in avoiding breakdowns and in proper planning of preventive and predictive maintenance. With increasing use of on-line computerised controls the generation of design base data and also the in-built self checking feature of monitoring the equipment health can be achieved by incorporating suitable software. This type of system will be helpful in: (a) predicting the life of component, (b) prewarning the operator about impending malfunctions, (c) establishing a maintenance schedule and spare inventory, and (d) analysing the failures. This type of centralised predictive maintenance is increasingly becoming important where: (a) the number of equipments are large, (b) the operation of equipment is critical from safety criteria, and (c) the minimum safety margin in the performance of the component is to be maintained. Keeping this in mind, the Fuel Handling System of Narora Atomic Power Project and the future power plants having computerised controls will have facility for on-line performance monitoring for predictive maintenance. The paper also describes methodology of the technique in detail, with a few representative cases. (author)

Depression is a major cause of disability worldwide, and computerised cognitive behavioural therapy (CCBT) is expected to be a more augmentative and efficient treatment. According to previous meta-analyses of CCBT, there is a need for a meta-analytic revaluation of the short-term effectiveness of this therapy and for an evaluation of its long-term effects, functional improvement and dropout. Five databases were used (MEDLINE, PsycINFO, EMBASE, CENTRAL and CiNii). We included all RCTs with proper concealment and blinding of outcome assessment for the clinical effectiveness of CCBT in adults (aged 18 and over) with depression. Using Cohen's method, the standard mean difference (SMD) for the overall pooled effects across the included studies was estimated with a random effect model. The main outcome measure and the relative risk of dropout were included in the meta-analysis. Fourteen trials met the inclusion criteria, and sixteen comparisons from these were used for the largest meta-analysis ever. All research used appropriate random sequence generation and Intention-to-Treat analyses (ITT), and employed self-reported measures as the primary outcome. For the sixteen comparisons (2807 participants) comparing CCBT and control conditions, the pooled SMD was -0.48 [95% IC -0.63 to -0.33], suggesting similar effect to the past reviews. Also, there was no significant clinical effect at long follow-up and no improvement of function found. Furthermore, a significantly higher drop-out rate was found for CCBT than for controls. When including studies without BDI as a rating scale and with only modern imputation as sensitivity analysis, the pooled SMD remained significant despite the reduction from a moderate to a small effect. Significant publication bias was found in a funnel plot and on two tests (Begg's p = 0.09; Egger's p = 0.01). Using a trim and fill analysis, the SMD was -0.32 [95% CI -0.49 to -0.16]. Despite a short-term reduction in depression at post-treatment, the

The School System and New Media – Reasons in Favour of Integration

Directory of Open Access Journals (Sweden)

M. Marković

2017-06-01

Full Text Available In the education system reform which is currently underway in Serbia and in most countries of the region, considerable attention has been paid to modern media technologies. Although a whole decade has passed since the initiation of the reform there have been no significant developments regarding the school system computerisation, which resulted in raising the issue of integration and seeking valid arguments which indicate the key role of new media in the re-structuring of the school system. In that context, the basic goal of this paper is an analysis of primary research studies which suggest the reasons for the inte-gration of new media into the school system in order to set out the reform guidelines regarding the application of information and communication tech-nologies in formal education. The results of the analysis attest to a large num-ber of compelling reasons for implementing modern media technologies into the system of educational institutions. Among them one should distinguish the general reasons which deal with improving the quality of and bridging the gap between formal and informal education. The selected research studies state objective reasons such as rationality and cost-effectiveness, as well as peda-gogical reasons relating to the learning context innovation, presence of new knowledge sources provided by Internet resources, changes in the process of learning instigated by the development of e-learning and a higher motivation of the participants in the process of education. In the conclusion of this re-search the authors emphasise the necessity of integrating media technologies into the school system for the purposes of creating a modern coherent system founded on networking, communication and exchange.

Shakespeare’s Weird Sisters – In Between Outlandish Womanhood and Prophesing Moirae

2017-12-01

Full Text Available This study intends to map the meandering expression of otherness when womanhood constructs an epiphanic encounter with time and fortune. Hereinafter, hegemonic, oppressive masculinity meets peripheral, prophesying femininity in an intricate exercise of doing and becoming Shakespeare‘s Weird Sisters, forming a complex mythological construction, whose uniqueness arises from the duality of their personae, reflection of displaced femininity, somewhat grotesque, peripheral within the realm of marginality itself. They are not only weird expressions of the Other, they are the other self of themselves, as alter ego expressions. There is a constant, minutely woven border crossing that does not only (redefine the geometry of becoming, but it also permeates gender constructions, making femaleness look androgynous and ruthless. Foretelling dreams of glory, mightiness or summoning lost humanity, these three Parcae rewrite the myth of the androgynous and its story about the quest of the Other. It is this Other that will be explored from a variety of angles that speak of masculinity, femininity, sanity, irrationality, consciousness, unconsciousness, freewill and fate.

In olden days people mostly worked within circle or walkable distance but now the technology developing day by day to reduce the work as well as time taken by work to complete.Thestuff’s in our daily process, somehow we left some lot of work due to lack of time. In today’s life most probably utmost 50% of products all came with automation and making theconsumers/users to access those products from anywhere by using their mobile or gadgets. In this paper, it deals with automation of fuel station retail outlet; this system will give the sales and stock report to the owner for every hour. The main problem is customer complaints about less quantityof fuel is issued or filled for money given and customers get diverted theirs attention by operators and refill the fuel without they resetting the nozzle. Nowadays to overcome these problems they replaced some electronic and computerised fuel dispensers but there is no way to identify inside the rotary valve adjustments by fitter.

Design of the real time systems using temporal logic specifications: a case study

Directory of Open Access Journals (Sweden)

A. Ursu

1996-07-01

Full Text Available An implementation method for real time systems is proposed in this article. The implementation starts with the design of the functional specifications of the systems behaviour. The functional specifications are introduced as a set of rules describing the partial time ordering of the actions performed by the system. These rules are then written in terms of temporal logic formulae. The temporal logic formulae are checked using Z.Manna-P.Wolper satisfiability analysis procedure [1]. It is known that this procedure generates a state-graph which can be regarded as a state- based automaton of the system. The sate-based automaton is used then to generate the dual (inverted automaton of the system. The dual automaton is called action-based automaton and can be created using the procedure proposed by authors in [4,5]. Using the action-based automaton of the system the design method introduced in [5,6] is applied to implement the system driver in a systematic manner which can be computerised. The method proposed in this paper is an efficient complementation and generalisation of the results [4,5,6] mentioned above. The method is used for a case study. An elevator control system is designed using the proposed method. The design is carried out in a systematic manner which includes: a design of functional specifications, b design of temporal logic specifications, c satisfiability analysis of temporal logic specifications, d design of the state-based automaton of the specifications, e design of the action-based automaton of the system, f design of the transition activation conditions, g design of the action activation conditions, h design of the functional model of the elevator control system, i implementation of the elevator's actions, j design of the elevator control system driver.

During the firing of bricks, mineralogical and textural transformations produce an artificial aggregate characterised by significant porosity. Particularly as regards pore-size distribution and the interconnection model, porosity is an important parameter to evaluate and predict the durability of bricks. The pore system is in fact the main element, which correlates building materials and their environment (especially in cases of aggressive weathering, e.g., salt crystallisation and freeze-thaw cycles) and determines their durability. Four industrial bricks with differing compositions and firing temperatures were analysed with “direct” and “indirect” techniques, traditional methods (mercury intrusion porosimetry, hydric tests, nitrogen adsorption) and new analytical approaches based on digital image reconstruction of 2D and 3D models (back-scattered electrons and computerised X-ray micro-Tomography, respectively). The comparison of results from different analytical methods in the “overlapping ranges” of porosity and the careful reconstruction of a cumulative curve, allowed overcoming their specific limitations and achieving better knowledge on the pore system of bricks. - Highlights: •Pore-size distribution and structure of the pore system in four commercial bricks •A multi-analytical approach combining “direct” and “indirect” techniques •Traditional methods vs. new approaches based on 2D/3D digital image reconstruction •The use of “overlapping ranges” to overcome the limitations of various techniques.

Development of an on-line electrochemical analyser for trace level aluminium

Chow, Christopher W.K.; Thomas, Shaun D.; Davey, David E.; Mulcahy, Dennis E.; Drikas, Mary

2003-01-01

An in-house designed computerised flow injection (FI) system for low-level aluminium analysis is examined. A simple, low cost electrochemical detection system has been implemented with computerised control and data acquisition system. The system consists of a commercial electrochemical analyser, FI components (manifold, pumps and valves) and an in-house designed control system to perform automated analysis. This system was developed to study aluminium speciation in water, particularly for drinking water. The analytical technique was based upon the complexation reaction between aluminium and a ligand--DASA (1,2-dihydroxy-anthraquinone-3-sulphonic acid). 'Labile' and total aluminium concentrations, Al labile and Al total , respectively, were determined by measuring the sample before and after UV irradiation by amperometry at +0.6 V. The limit of detection for this technique was 10 μg/l (0.37 μM) and the linear calibration range was up to 1.6 mg/l (60 μM) with r 2 value of 0.999. The Al labile /Al total ratios of the water treated by 40, 80 and 100 mg/l of alum using a laboratory scale pilot plant to simulate conventional drinking water treatment processes were found to be 0.4, 0.5 and 0.8, respectively. These results indicated that when higher alum dose was employed, the residual aluminium was present mostly as the 'labile' species. Whereas, if the treatment process was not running at its optimum condition (underdosing), a large portion of aluminium was present as natural organic matter (NOM) - aluminium complexes in the treated water. The system offers a practical and effective means of providing extended knowledge of residual aluminium in drinking water

2013-09-01

Full Text Available Background UK primary care physicians receive their laboratory test results electronically. This study reports a computerised physician order entry (CPOE system error in the pathology test request date that went unnoticed in family practices.Method We conducted a case study using a causation of risk theoretical framework; comprising interviews with clinicians and the manufacturer to explore the identification of and reaction to the error. The primary outcome was the evolution and  recognition of and response to the problem. The secondary outcome was to identify other issues with this system noted by users.Results The problem was defined as the incorrect logging of test dates ordered through a CPOE system. The system assigned the test request date to the results, hence a blood test taken after a therapeutic intervention (e.g. an increase in cholesterol-lowering therapy would appear in the computerised medical record as though it had been tested prior to the increase in treatment. This case demonstrates that: the manufacturers failed to understand family physician workflow; regulation of medical software did not prevent the error; and inherent user trust in technology exacerbated this problem. It took three months before users in two practices independently noted the date errors.Conclusion This case illustrates how users take software on trust and suppliers fail to make provision for risks associated with new software. Resulting errors led to inappropriate prescribing, follow-up, costs and risk. The evaluation of such devices should include utilising risk management processes (RMP to minimise and manage potential risk.

During the rapid growth of computerised systems in the past 15 years, the variety of services and their efficiency have been the strongest deciding factors in design and development of the systems within various industrial branches. At the same time, the introduction and popularity of emerging design and development techniques seems to have forced the industry to include these in their product development process. Unfortunately, too many examples of lack of use or erroneous use of these techniques within industries such as telecommunications, telemedicine, aerospace and indeed the energy sector indicate that a common understanding of and belief in the rationale behind the techniques and their solution domains has not been obtained. At the same time, a tremendous increase in the number of emerging techniques has made such an understanding difficult to gain, especially when the techniques share the same application field, but differ in few yet important issues. Finally, the lack of knowledge about system aspects and the integration of various abstraction levels to describe them have added even more to the confusion on how to use different techniques. The work resulting in the Capability-Oriented Agent Theory began while trying to find more descriptive system models, taking into account a wider selection of system aspects. Although related to object-oriented and agent-oriented principles, the theory differs from such principles in many respects. Among others, its focal point is on a category of system aspects neither addressed nor recognised within such principles before. Additionally, the theory opposes the well-established idea of distinct separation between requirement, design, implementation and test specifications, but suggests a systematic integration of the related activities, hence to increase their traceability and intercommunication in both a top-down and a bottom-up manner along the development process.

Analysing the doctor_patient_computer relationship: the use of video data

Directory of Open Access Journals (Sweden)

Christopher Pearce

2006-12-01

Full Text Available This paper examines the utility of using digital video data in observational studies involving doctors' and patients' use of computers in the consultation. Previous observational studies have used either direct observations or analogue videotapes. We describe a method currently in use in a study examining how doctors, patients and computers interact in the consultation. The study is set in general practice as this is the most clinically computerised section of the Australian healthcare system. Computers are now used for clinical functions in 90% of doctors' surgeries. With this rapid rise of computerisation, concerns have been expressed as to how the computer will affect the doctor_patient relationship. To assess how doctors, patients and computers interact, we have chosen an observational technique, namely to make digital videotapes of actual consultations. This analysis is based on a theoretical framework derived from dramaturgical analysis. Data are gathered from general practitioners who are high-level users of computers, as defined by their use of progress notes, as well as prescribing and test ordering. The subsequent digital data is then transferred onto computer and analysed according to our conceptual framework, making use of video-tagging software.

UK general practice is universally computerised, with computers used in the consulting room at the point of care. Practices use a range of different brands of computer system, which have developed organically to meet the needs of general practitioners and health service managers. Unified Modelling Language (UML) is a standard modelling and specification notation widely used in software engineering. To examine the feasibility of UML notation to compare the impact of different brands of general practice computer system on the clinical consultation. Multi-channel video recordings of simulated consultation sessions were recorded on three different clinical computer systems in common use (EMIS, iSOFT Synergy and IPS Vision). User action recorder software recorded time logs of keyboard and mouse use, and pattern recognition software captured non-verbal communication. The outputs of these were used to create UML class and sequence diagrams for each consultation. We compared 'definition of the presenting problem' and 'prescribing', as these tasks were present in all the consultations analysed. Class diagrams identified the entities involved in the clinical consultation. Sequence diagrams identified common elements of the consultation (such as prescribing) and enabled comparisons to be made between the different brands of computer system. The clinician and computer system interaction varied greatly between the different brands. UML sequence diagrams are useful in identifying common tasks in the clinical consultation, and for contrasting the impact of the different brands of computer system on the clinical consultation. Further research is needed to see if patterns demonstrated in this pilot study are consistently displayed.

The computer-based electronic medical record (EMR) is an essential new technology in health care, contributing to high-quality patient care and efficient patient management. The majority of southern European countries, however, have not yet implemented universal EMR systems and many efforts are still ongoing. We describe the development of an EMR system and its pilot implementation and evaluation in two previously computer-naïve public primary care centres in Cyprus. One urban and one rural primary care centre along with their personnel (physicians and nurses) were selected to participate. Both qualitative and quantitative evaluation tools were used during the implementation phase. Qualitative data analysis was based on the framework approach, whereas quantitative assessment was based on a nine-item questionnaire and EMR usage parameters. Two public primary care centres participated, and a total often health professionals served as EMR system evaluators. Physicians and nurses rated EMR relatively highly, while patients were the most enthusiastic supporters for the new information system. Major implementation impediments were the physicians' perceptions that EMR usage negatively affected their workflow, physicians' legal concerns, lack of incentives, system breakdowns, software design problems, transition difficulties and lack of familiarity with electronic equipment. The importance of combining qualitative and quantitative evaluation tools is highlighted. More efforts are needed for the universal adoption and routine use of EMR in the primary care system of Cyprus as several barriers to adoption exist; however, none is insurmountable. Computerised systems could improve efficiency and quality of care in Cyprus, benefiting the entire population.

Its major strengths are that it has wide usage, has codes specific to sports medicine and that it is free to use. Literature searches and stakeholder consultations were made to assess the uptake of OSICS and to develop new versions. OSICS was commonly used in the sports of football (soccer, Australian football, rugby union, cricket and tennis. It is referenced in international papers in three sports and used in four commercially available computerised injury management systems. Suggested injury categories for the major sports are presented. New versions OSICS 9 (three digit codes and OSICS 10.1 (four digit codes are presented. OSICS is a potentially helpful component of a comprehensive sports injury surveillance system, but many other components are required.

Practices to prevent venous thromboembolism: a brief review

Science.gov (United States)

Lau, Brandyn D; Haut, Elliott R

2014-01-01

Background Venous thromboembolism (VTE) is a common cause of preventable harm for hospitalised patients. Over the past decade, numerous intervention types have been implemented in attempts to improve the prescription of VTE prophylaxis in hospitals, with varying degrees of success. We reviewed key articles to assess the efficacy of different types of interventions to improve prescription of VTE prophylaxis for hospitalised patients. Methods We conducted a search of MEDLINE for key studies published between 2001 and 2012 of interventions employing education, paper based tools, computerised tools, real time audit and feedback, or combinations of intervention types to improve prescription of VTE prophylaxis for patients in hospital settings. Process outcomes of interest were prescription of any VTE prophylaxis and best practice VTE prophylaxis. Clinical outcomes of interest were any VTE and potentially preventable VTE, defined as VTE occurring in patients not prescribed appropriate prophylaxis. Results 16 articles were included in this review. Two studies employed education only, four implemented paper based tools, four used computerised tools, two evaluated audit and feedback strategies, and four studies used combinations of intervention types. Individual modalities result in improved prescription of VTE prophylaxis; however, the greatest and most sustained improvements were those that combined education with computerised tools. Conclusions Many intervention types have proven effective to different degrees in improving VTE prevention. Provider education is likely a required additional component and should be combined with other intervention types. Active mandatory tools are likely more effective than passive ones. Information technology tools that are well integrated into provider workflow, such as alerts and computerised clinical decision support, can improve best practice prophylaxis use and prevent patient harm resulting from VTE.

A. Degli Esposti and A. Abbati: Computerised gamma-camera 99/sup m/ Tc-albumin angiocardiography in the morphological and dynamic examination of children with congenital heart disease. A number of cases in which computerised gamma-camera 99/sup m/ Tc-albumin angiocardiography was employed in children with congenital heart diseases are described. Comparison is made with the data obtained contrastographically, or during surgery or necropsy. The preliminary results, particularly in recently examined subjects, whose data were processed in a more efficient manner, point to the usefulness of the method. Though incapable of offering the same morphological precision as contrastography, it has the advantage of being absolute harmless and, above all, repeatable.

how the National Service Framework (NSF) for older people in England might be associated with changes in clinically relevant stroke outcome has not been investigated. We looked for changes in computerised tomography (CT) scan rate, inpatient case-fatality rate (CFR), length of acute hospital stay and discharge destination for older people with stroke, compared with their younger counterparts, for a period before, and after, the introduction of the NSF. two periods, 4 years before and 2 years after the publication of the NSF, were selected to compare the above outcomes between three age categories: or = 85 years of age. Annual summary data for these periods were compared for the magnitude of changes in all age categories for all outcomes measured between pre- and post-NSF periods. n = 5,219. Utilisation of CT imaging had increased in all age groups post-NSF, with the most significant improvement in the oldest group. This change was associated with a greater proportion of people who had CT in this age group being discharged home in the post-NSF period. There was no change in the mortality from stroke in any age group during the study. Although the length of acute hospital stay increased, this was associated with a higher percentage of home discharges particularly in > 65-year olds, suggesting better clinical outcome in those who survived. in this single-centre analysis, the post-NSF period appeared to be associated with improvement in outcome in older people with stroke. Continual monitoring using stroke registry data may help to assess whether these effects are sustained in the longer term.

Safety against releases in severe accidents. Final report

1997-12-01

The work scope of the RAK-2 project has involved research on quantification of the effects of selected severe accident phenomena for Nordic nuclear power plants, development and testing of a computerised accident management support system and data collection and description of various mobile reactors and of different reactor types existing in the UK. The investigations of severe accident phenomena focused mainly on in-vessel melt progression, covering a numerical assessment of coolability of a degraded BWR core, the possibility and consequences of a BWR reactor to become critical during reflooding and the core melt behavior in the reactor vessel lower plenum. Simulant experiments were carried out to investigate lower head hole ablation induced by debris discharge. In addition to the in-vessel phenomena, a limited study on containment response to high pressure melt ejection in a BWR and a comparative study on fission product source term behaviour in a Swedish PWR were performed. An existing computerised accident management support system (CAMS) was further developed in the area of tracking and predictive simulation, signal validation, state identification and user interface. The first version of a probabilistic safety analysis module was developed and implemented in the system. CAMS was tested in practice with Barsebaeck data in a safety exercise with the Swedish nuclear authority. The descriptions of the key features of British reactor types, AGR, Magnox, FBR and PWR were published as data reports. Separate reports were issued also on accidents in nuclear ships and on description of key features of satellite reactors. The collected data were implemented in a common Nordic database. (au)

The correlation between the different accelerated aging methods and operation reality has to be done with solid and representative elements in matter of tests as well as in operating experience. In 1990 in France, the first unit will be 13 years operating, there will be 34 units of 900 MW PWR and 18 units of 1300 MW PWR in operation. The total of experience will be equivalent to 400 reactor-years. Only computerised means permit to collect all corresponding events, to manage them and to draw a lot of conclusions. One describes these computerised applications explaining the different events collected, data input and interrogating possibilities. The first application, called ''events file'', records all important events in nuclear plants. For each of these events, an event reporting format is set up as soon as first informations are known and then is put into the file. An updating is performed when the event is better known and analyzed. Interrogating programs allow no specialist to access easily to this data bank. So it is possible to collect events of the same nature, of the same equipments or of the same systems. The second application called S.R.D.F. (fiability data bank system) collects all maintenance operations on certain mechanical and electrical equipment. These two computerized applications complete on another in the way they allow to do fiability and availability studies for some equipments or for some elements of a nuclear plant [fr

Starting from the premise that such failure is a common aspect of the everyday order of life, I reread the encounter through the work of Moira von Wright, Kelly Oliver, Gert Biesta and Adriana Cavarero, asking three questions. What is the interpersonal cost of a relationship which fails to recognize lived human uniqueness? Does it make a difference for the politicsof schooling whether interpersonal relationships exclude or leave space for those involved in them to appreciate each other as unique, living beings? What difficulties and opportunities exist for the possibility of appearing and appreciating oneself and others as unique existents within a student-teacher relation that is experienced as specific, embodied and altruistic? I argue that attending sensually to the other can open and safeguard a relational space for the appearance of uniqueness.

2002-01-01

Following the Chernobyl accident, computerised systems for off-site management and response in case of a nuclear accident were developed and installed in many European countries. Some of the systems are in use in only one country, whereas other systems have found broader application in Europe. Examples of these systems are IMIS (D), ARGOS (DK), running in Denmark, Lithuania and Poland and RODOS, a real-time on-line decision support system for nuclear emergency management in Europe, which is now installed for operational or test-operational use in many European countries. During the development and installation phases of these decision support systems the necessity emerged, that there is a need for an intensive feedback between developers and users. Therefore, under the 5. Framework Programme of the European Commission a network has been installed to intensify the communication and increase the understanding between the operational community and the many and diverse disciplines involved in RD for improvement, extension and integration of operational decision support systems for nuclear emergency management, called DSSNET. This poster demonstrates how the network is organised, namely with different work groups, exercises and meetings. Each working group addresses one of seven work packages: - Preparation and conduct of exercises (WP1), - User interfaces, results and interaction with decision makers (WP2), - Exchange of data information relevant for decision-making (WP3), System functions, networks and processing of on-line data (WP4), European database (WP5), Coordination of the network (WP6), Hydrological modelling (WP7). Main focus is given to WP4, in which information of on-line monitoring from more than 10 European counties is collected. Information was collated with the help of questionnaires which are send out on a regular basis. The evaluation of the various questionnaires summarises the different systems in use for stack monitoring, retrieving on

Patients with long-standing constipation were examined by radioisotope proctography. A radiolabelled synthetic potato mash was inserted intrarectally and the dynamic changes during simulated defaecation recorded using a gamma-camera. Computer images from the stored data illustrate changes in the anorectal angle and pelvic floor. The median (and 95% confidence intervals) of the anorectal angles were: At rest 105deg (101deg, 116deg), on voluntary contraction of the pelvic floor by 'squeezing' 91deg (81deg, 98deg), on straining 120deg (107deg, 137deg) and during evacuation 126deg (116deg, 153deg). The pelvic floor movements were: Pelvic floor ascent on voluntary contraction 28 mm (9, 34 mm), pelvic floor descent on straining -8 mm (-14, -4 mm) and descent during evacuation -27 mm (-34, -11 mm). Useful additions to previous methods are measurement of the completeness of rectal evacuation 58% (42, 77 mm), the defaecation time 64 s (50, 138 s) and the defaecation rate 0.9%/s (0.4, 1.4%/s).

Diagnosis of attention deficit hyperactivity disorder (ADHD) relies on subjective methods which can lead to diagnostic uncertainty and delay. This trial evaluated the impact of providing a computerised test of attention and activity (QbTest) report on the speed and accuracy of diagnostic decision-making in children with suspected ADHD. Randomised, parallel, single-blind controlled trial in mental health and community paediatric clinics in England. Participants were 6-17 years-old and referred for ADHD diagnostic assessment; all underwent assessment-as-usual, plus QbTest. Participants and their clinician were randomised to either receive the QbTest report immediately (QbOpen group) or the report was withheld (QbBlind group). The primary outcome was number of consultations until a diagnostic decision confirming/excluding ADHD within 6-months from baseline. Health economic cost-effectiveness and cost utility analysis was conducted. Assessing QbTest Utility in ADHD: A Randomised Controlled Trial was registered at ClinicalTrials.gov (https://clinicaltrials.gov/ct2/show/NCT02209116). One hundred and thirty-two participants were randomised to QbOpen group (123 analysed) and 135 to QbBlind group (127 analysed). Clinicians with access to the QbTest report (QbOpen) were more likely to reach a diagnostic decision about ADHD (hazard ratio 1.44, 95% CI 1.04-2.01). At 6-months, 76% of those with a QbTest report had received a diagnostic decision, compared with 50% without. QbTest reduced appointment length by 15% (time ratio 0.85, 95% CI 0.77-0.93), increased clinicians' confidence in their diagnostic decisions (odds ratio 1.77, 95% CI 1.09-2.89) and doubled the likelihood of excluding ADHD. There was no difference in diagnostic accuracy. Health economic analysis showed a position of strict dominance; however, cost savings were small suggesting that the impact of providing the QbTest report within this trial can best be viewed as 'cost neutral'. QbTest may increase the

Acute superior vena caval syndrome with airway obstruction following elective mediastinoscopy.

A 47-year-old female patient had a subclinical superior vena caval syndrome which developed into the \\'full blown\\' acute condition when she was placed into the left lateral position after mediastinoscopy. She developed airway obstruction requiring urgent re-intubation and subsequent admission to the intensive care unit. This subclinical condition might have been suspected pre-operatively if closer attention had been paid to the history, physical examination and review of the computerised axial tomography scan: she had a history of intermittent dysponea, wheeze and cough which was worse on waking and improved as the day progressed, she had a positive Pemberton\\'s sign and the computerised axial tomography scan showed that the lesion was encroaching on the superior vena cava.

Full Text Available Background: We will be unable to achieve sustained impact on health outcomes with community health worker (CHW-based interventions unless we bridge the gap between small scale efficacy studies and large scale interventions. Effective strategies to support the management of CHWs are central to bridging the gap. Mobile phones are broadly available, particularly in low and middle income countries (LAMIC, where the penetration rate approaches 100%. Objectives: In this article, we describe how mobile phones and may be combined with mobile web-based technology to assist in the management of CHWs in two projects in South Africa. Methods: This article is a descriptive study, drawing lessons from two randomised controlled trials outlining how a mobile phone information system can be utilised to enhance the quality of health interventions. We organised our comprehensive management and supervision system around a previously published management framework. The system is composed of mobile phones utilised by CHWs and a web-based interface utilised by CHW supervisors. Computerised algorithms were designed with intervention and assessment protocols to aid in the real-time supervision and management of CHWs. Results: Community health workers used mobile phones to initiate intervention visits and trigger content to be delivered during the course of intervention visits. Supervisors used the web-based interface for real-time monitoring of the location, timing and content of intervention visits. Additional real-time support was provided through direct support calls in the event of crises in the field. Conclusion: Mobile phone-based information system platforms offer significant opportunities to improve CHW-delivered interventions. The extent to which these efficiency gains can be translated into realised health gains for communities is yet to be tested.

2006-11-01

Full Text Available Abstract Background Diagnostic error is a significant problem in specialities characterised by diagnostic uncertainty such as primary care, emergency medicine and paediatrics. Despite wide-spread availability, computerised aids have not been shown to significantly improve diagnostic decision-making in a real world environment, mainly due to the need for prolonged system consultation. In this study performed in the clinical environment, we used a Web-based diagnostic reminder system that provided rapid advice with free text data entry to examine its impact on clinicians' decisions in an acute paediatric setting during assessments characterised by diagnostic uncertainty. Methods Junior doctors working over a 5-month period at four paediatric ambulatory units consulted the Web-based diagnostic aid when they felt the need for diagnostic assistance. Subjects recorded their clinical decisions for patients (differential diagnosis, test-ordering and treatment before and after system consultation. An expert panel of four paediatric consultants independently suggested clinically significant decisions indicating an appropriate and 'safe' assessment. The primary outcome measure was change in the proportion of 'unsafe' workups by subjects during patient assessment. A more sensitive evaluation of impact was performed using specific validated quality scores. Adverse effects of consultation on decision-making, as well as the additional time spent on system use were examined. Results Subjects attempted to access the diagnostic aid on 595 occasions during the study period (8.6% of all medical assessments; subjects examined diagnostic advice only in 177 episodes (30%. Senior House Officers at hospitals with greater number of available computer workstations in the clinical area were most likely to consult the system, especially out of working hours. Diagnostic workups construed as 'unsafe' occurred in 47/104 cases (45.2%; this reduced to 32.7% following system

One of the most serious risks of blood transfusions is an error in ABO blood group compatibility, which can cause a haemolytic transfusion reaction and, in the most severe cases, the death of the patient. The frequency and type of errors observed suggest that these are inevitable, in that mistakes are inherent to human nature, unless significant changes, including the use of computerised instruments, are made to procedures. In order to identify patients who are candidates for the transfusion of blood components and to guarantee the traceability of the transfusion, the Securblood system (BBS srl) was introduced. This system records the various stages of the transfusion process, the health care workers involved and any immediate transfusion reactions. The patients and staff are identified by fingerprinting or a bar code. The system was implemented within Ragusa hospital in 16 operative units (ordinary wards, day hospital, operating theatres). In the period from August 2007 to July 2008, 7282 blood components were transfused within the hospital, of which 5606 (77%) using the Securblood system. Overall, 1777 patients were transfused. In this year of experience, no transfusion errors were recorded and each blood component was transfused to the right patient. We recorded 33 blocks of the terminals (involving 0.6% of the transfused blood components) which required the intervention of staff from the Service of Immunohaematology and Transfusion Medicine (SIMT). Most of the blocks were due to procedural errors. The Securblood system guarantees complete traceability of the transfusion process outside the SIMT and eliminates the possibility of mistaken identification of patients or blood components. The use of fingerprinting to identify health care staff (nurses and doctors) and patients obliges the staff to carry out the identification procedures directly in the presence of the patient and guarantees the presence of the doctor at the start of the transfusion.

In a Nuclear Power Plant, the developed power is proportional to the emitted neutron flux. The 10 to 11 decades measurement range from source to power generally needs 3 distinct neutron measurement chains to be monitored. A wide range neutron monitoring system may cover this range with only one sensor followed by adequate electronics. In the past this concept has been developed with an analogue technology which was presenting some drawbacks (slow log amplifier, components perenniality). In this paper, we introduce a completely new design, that makes use of a recent technology, including full linear input electronics, and advanced digital signal processing. As far as the sensor is concerned, both a well known commercial fission chamber, or an innovative wide range sensor presenting a high sensitivity may be used. The basic concept is that the single signal is continuously processed by three different electronic stages, each one being dedicated to approximately one third of the full range: pulse, Campbelling and current modes. After amplification, appropriate shaping, this signal is numerically filtered by a Kalman filter algorithm to compute the neutron flux as well as the reactor period. A specifically developed test module allows the surveillance of the sensor and the electronics via stimuli injections and characteristic curves plotting. A computerised simulation of the whole chain is used to validate the signal processing algorithms evolutions. In the paper we will specifically develop the metrological performances of this chain and the general agreement that exists between simulated and measured values. (authors)

Within the frame of growing energy demand caused by global economic growth and taking into account the Kyoto protocol on carbon dioxide emissions nuclear power plants attaining a new role. The presented papers deal mostly with improvements in NPP design, construction and safety. Some new concepts are proposed, especially in the field of inherent or passive reactor safety as well as computerised control systems. Water cooled reactors achieved already the necessary cost reduction but require some radical thinking in fuel design, construction rate, built-in safety. The key factor will be mass production in order to attain capital cost of half today's level

The aim of this study was to evaluate the predictive potential provided by two ventilatory inflection points (VIP1 and VIP2) examined in field without using gas analysis systems and uncomfortable facemasks. A calibrated respiratory inductance plethysmograph (RIP) and a computerised routine were utilised, respectively, to derive ventilation and to detect VIP1 and VIP2 during a standardised field ramp test on a 400 m running track on 81 participants. In addition, average running speed of a competitive 1000 m run (S1k) was observed as criterion. The predictive value of running speed at VIP1 (SVIP1) and the speed range between VIP1 and VIP2 in relation to VIP2 (VIPSPAN) was analysed via regression analysis. VIPSPAN rather than running speed at VIP2 (SVIP2) was operationalised as a predictor to consider the covariance between SVIP1 and SVIP2. SVIP1 and VIPSPAN, respectively, provided 58.9% and 22.9% of explained variance in regard to S1k. Considering covariance, the timing of two ventilatory inflection points provides predictive value in regard to a competitive 1000 m run. This is the first study to apply computerised detection of ventilatory inflection points in a field setting independent on measurements of the respiratory gas exchange and without using any facemasks.

This paper presents a partition based approach for handling very large tables with size running in giga-bytes to tera-bytes. The scheme is developed from our experience in handling large signal storage which is required in various computer based data acquisition and control room operator information systems such as Distribution Recording System (DRS) and Computerised Operator Information System (COIS). Whenever there is a disturbance in an operating nuclear power plant, it triggers an action where a large volume of data from multiple sources is generated and this data needs to be stored. Concurrency issues as data is from multiple sources and very large amount of data are the problems which are addressed in this paper by applying partition based approach. Advantages of partition based approach with other techniques are discussed. (author)

The French Institutions involved in LMFRs development (EDF Utilities, CEA Research Institute and FRAMATOME-ANP Engineering) decided in 2000 year to preserve the R and D knowledge which was raised during the last four decades of the 20th century: the long term availability (some decades) of LMFRs experience should be maintained thanks to an extensive, everlasting and intelligible form which could allow future designers to use this great amount of knowledge. Among different types of architecture, the LMFRs Fund of Knowledge is being raised in 2001 and 2002 along two complementary ways: - The main one gives an overall vision of R and D work undertaken through 23 R and D items: an overall view of LMFRs conception; 9 items about Core R and D work (Safety, Working, Thermohydraulics, Thermomechanics, Design Rules, Materials, Fuel clad failure, Neutronics, Nuclear fuel; 13 items about Reactor R and D work (Safety, Working, Sodium Coolant, Sodium Technology, Thermohydraulics, cover gas Aerolics, Thermomechanics, Design Rules, in sodium equipment Mechanics, Materials, In Service Inspection and Repair, Sodium Fires, Decommissioning). - The other one deals with the Design of what can be a LMFR: Superphenix Plant was chosen as the largest and validated industrial size LMFR through the conception of its 41 systems (Core system, Monitoring systems, Protective and Shut-down systems, Primary systems, Secondary and Steam Generator Systems, Decay Heat Removal system, Primary and secondary Handling systems, Cleaning and Decontamination systems, Fuel Storage system). Each R and D item and each Superphenix system is described with a Documentary Form, written by French specialist: after a brief description of the different sub-items (some pages), the list of relevant references are listed (some dozens to some hundreds of synthesis reports, basic literature, specialist interviews, Superphenix measurement data, EFR Project synthesis). Thus, the LMFRs Fund of Knowledge is made of the 64

Computerised order sets have the potential to reduce clinical variation and improve patient safety but the effect is variable. We sought to evaluate the impact of changes to the design of an order set on the delivery of chlorhexidine mouthwash and hydroxyethyl starch (HES) to patients in the intensive care unit. The study was conducted at University Hospitals Bristol NHS Foundation Trust, UK. Our intensive care unit uses a clinical information system (CIS). All drugs and fluids are prescribed with the CIS and drug and fluid charts are stored within a database. Chlorhexidine mouthwash was added as a default prescription to the prescribing template in January 2010. HES was removed from the prescribing template in April 2009. Both interventions were available to prescribe manually throughout the study period. We conducted a database review of all patients eligible for each intervention before and after changes to the configuration of choices within the prescribing system. 2231 ventilated patients were identified as appropriate for treatment with chlorhexidine, 591 before the intervention and 1640 after. 55.3% were prescribed chlorhexidine before the change and 90.4% after (p<0.001). 6199 patients were considered in the HES intervention, 2177 before the intervention and 4022 after. The mean volume of HES infused per patient fell from 630 mL to 20 mL after the change (p<0.001) and the percentage of patients receiving HES fell from 54.1% to 3.1% (p<0.001). These results were well sustained with time. The presentation of choices within an electronic prescribing system influenced the delivery of evidence-based interventions in a predictable way and the effect was well sustained. This approach has the potential to enhance the effectiveness of computerised order sets.

Computers are increasingly used to improve prescribing decisions in the management of long-term conditions however the effects on asthma prescribing remain unclear. We aimed to synthesise the evidence for the use of computerised alerts that identify excessive prescribing of short-acting beta 2 -agonists (SABAs) to improve asthma management for people with asthma. MEDLINE, CINAHL, Embase, Cochrane and Scopus databases (1990-2016) were searched for randomised controlled trials using electronic alerts to identify excessive prescribing of SABAs for people with asthma in primary care. Inclusion eligibility, quality appraisal (Cochrane risk of bias tool) and data extraction were performed by two independent reviewers. Findings were synthesised narratively. A total of 2035 articles were screened and four trials were eligible. Three studies had low risk of bias: one reported a positive effect on our primary outcome of interest, excessive SABA prescribing; another reported positive effects on the ratio of inhaled corticosteroid (ICS)-SABA prescribing, and asthma control; a third reported no effect on outcomes of interest. One study at high risk of bias reported a reduction in exacerbations and primary care consultations. There is some evidence that electronic alerts reduce excessive prescribing of SABAs, when delivered as part of a multicomponent intervention in an integrated health care system. However due to the variation in health care systems, intervention design and outcomes measured, further research is required to establish optimal design of alerting and intervening systems.

Identification of individuals with high fracture risk from within primary care is complex. It is likely that the true contribution of falls to fracture risk is underestimated. Cross-sectional analysis of a population-based cohort of 3,200 post-menopausal women aged 73 ± 4 years. Self-reported data were collected on fracture, osteoporosis clinical risk factors and falls/mobility risk factors. Self-reported falls were compared with recorded falls on GP computerised records. Multivariable logistic regression was used to identify independent risk factors for fracture. A total of 838 (26.2%) reported a fracture after aged 50; 441 reported falling more than once per year, but 69% of these had no mention of falls on their computerised GP records. Only age [odds ratios (OR): 1.37 per 5 year increase, 95% confidence interval (CI): 1.23-1.53], height (1.02 per cm increase, 95% CI: 1.01-1.04), weight (OR: 0.99 per kg increase, 95% CI: 0.98-0.99) and falls (OR: 1.49 for more than once per year compared with less, 95% CI: 1.13-1.94) were independent risk factors for fracture. Falls had the strongest association. When identifying individuals with high fracture risk we estimate that more than one fall per year is at least twice as important as height and weight. Furthermore, using self-reported falls data is essential as computerised GP records underestimate falls prevalence.

The rapid development of computer and internet technology has a strong influence over one's quality of education within different fields of study. To determine the potential benefits of introducing internet into medical school classes, a pilot study was conducted in three different Chinese medical schools. Seven hundred and eight medical school undergraduates, 385 dental school students and 366 foreign students were randomly recruited to complete a self-administered questionnaire. The contents included personal information, current usage of computer and internet, and attitudes towards the computerised teaching methods. Two forum groups were created using instant message software and were randomly assigned to two classes, allowing students to freely ask or discuss questions with the help of their teachers in these two virtual classrooms. All 1539 questionnaires were accepted and analysed. Although there were some differences between Chinese and foreign undergraduates, both group of students were highly proficient in internet usage and navigation. Overwhelmingly, 88.37% of the students owned a computer and frequently logged onto the internet. Most of them believed that the internet is a helpful adjunct to their studies and held positive attitudes towards computerised teaching. Compared to the classes that were not assigned internet forums, the two experimental classes performed significantly better on the examination. Our results suggest that computerised teaching methods have significant potential to assist in learning for both Chinese and foreign medical undergraduates. © 2014 John Wiley & Sons A/S.

Using a generalised identity reference model with archetypes to support interoperability of demographics information in electronic health record systems.

Science.gov (United States)

Computerised identity management is in general encountered as a low-level mechanism that enables users in a particular system or region to securely access resources. In the Electronic Health Record (EHR), the identifying information of both the healthcare professionals who access the EHR and the patients whose EHR is accessed, are subject to change. Demographics services have been developed to manage federated patient and healthcare professional identities and to support challenging healthcare-specific use cases in the presence of diverse and sometimes conflicting demographic identities. Demographics services are not the only use for identities in healthcare. Nevertheless, contemporary EHR specifications limit the types of entities that can be the actor or subject of a record to health professionals and patients, thus limiting the use of two level models in other healthcare information systems. Demographics are ubiquitous in healthcare, so for a general identity model to be usable, it should be capable of managing demographic information. In this paper, we introduce a generalised identity reference model (GIRM) based on key characteristics of five surveyed demographic models. We evaluate the GIRM by using it to express the EN13606 demographics model in an extensible way at the metadata level and show how two-level modelling can support the exchange of instances of demographic identities. This use of the GIRM to express demographics information shows its application for standards-compliant two-level modelling alongside heterogeneous demographics models. We advocate this approach to facilitate the interoperability of identities between two-level model-based EHR systems and show the validity and the extensibility of using GIRM for the expression of other health-related identities.

In the safe operation of nuclear power plants and other complex process industries the performance of the control room crews plays an important role. In this respect a well-functioning and well-designed Human-System Interface (HSI) is crucial for safe and efficient operation of the plant. It is therefore essential that the design, development and evaluation of both control rooms and HSI-solutions are conducted in a well-structured way, applying sound human factors principles and guidelines in all phases of the HSI development process. Many nuclear power plants around the world are currently facing major modernisation of their control rooms. In this process computerised, screen-based HSIs replace old conventional operator interfaces. In new control rooms, both in the nuclear field and in other process industries, fully digital, screen-based control rooms are becoming the standard. It is therefore of particular importance to address the design and evaluation of screen-based HSIs in a systematic and consistent way in order to arrive at solutions which take proper advantage of the possibilities for improving operator support through the use of digital, screen-based HSIs, at the same time avoiding pitfalls and problems in the use of this technology. The Halden Reactor Project, in cooperation with the OECD Nuclear Energy Agency, organised an International Summer School on ''Design and Evaluation of Human-System Interfaces (HSIs)'' in Halden, Norway in the period August 25th - 29th, 2003. The Summer School addressed the different steps in design, development and evaluation of HSIs, and the human factors principles, standards and guidelines which should be followed in this process. The lectures comprised both theoretical background, as well as examples of good and bad HSI design, thereby providing practical advice in design and evaluation of operator interfaces and control room solutions to the participants in the Summer School.

To describe the adaptive capacity of the Adjusted Clinical Groups (ACG) system to the cost of care in primary healthcare centres in Catalonia (Spain). Retrospective study (multicentres) conducted using computerised medical records. 13 primary care teams in 2008 were included. All patients registered in the study centres who required care between 1 January and 31 December 2008 were finally studied. Patients not registered in the study centres during the study period were excluded. Demographic (age and sex), dependent (cost of care) and case-mix variables were studied. The cost model for each patient was established by differentiating the fixed and variable costs. To evaluate the adaptive capacity of the ACG system, Pearson's coefficient of variation and the percentage of outliers were calculated. To evaluate the explanatory power of the ACG system, the authors used the coefficient of determination (R(2)). The number of patients studied was 227 235 (frequency: 5.9 visits per person per year), with a mean of 4.5 (3.2) episodes and 8.1 (8.2) visits per patient per year. The mean total cost was €654.2. The explanatory power of the ACG system was 36.9% for costs (56.5% without outliers). 10 ACG categories accounted for 60.1% of all cases and 19 for 80.9%. 5 categories represented 71% of poor performance (N=78 887, 34.7%), particularly category 0300-Acute Minor, Age 6+ (N=26 909, 11.8%), which had a coefficient of variation =139% and 6.6% of outliers. The ACG system is an appropriate manner of classifying patients in routine clinical practice in primary healthcare centres in Catalonia, although improvements to the adaptive capacity through disaggregation of some categories according to age groups and, especially, the number of acute episodes in paediatric patients would be necessary to reduce intra-group variation.

Computerised self-evaluation of performance in professional English

Directory of Open Access Journals (Sweden)

Galina Kavaliauskienė

2014-10-01

Full Text Available Purpose – the focus of this article is to explore self-evaluation of performance in professional English that students have to do in university studies. It is clear that students can have various problems in learning English and make mistakes in listening, speaking, reading, writing, and vocabulary. Speaking and listening are the skills that are more common on an everyday basis than reading and writing. Speaking and listening skills have been known to be more difficult to master. English vocabulary presents another problem for language learners. At the university level, students study professional English, also called English for Specific Purposes (ESP. Students will need it for their future profession, so it is important for them to be able to evaluate their achievements in learning.Methodology/approach – the research paper adopts the qualitative research approach. The questionnaire on learner perceptions of computerized self-evaluation of various activities was administered to students of three different specializations. Students‘ perceptions of success or failure in their performance were analyzed.Findings. The results indicated that attitudes to computerized self-evaluation depended on the difficulty of tasks and chosen future specialization. The findings show that respondents of three investigated specializations encounter similar difficulties, but to a different degree. There are no specific problems in performance due to the complexity of the professional vocabulary that students must learn. The computations of Pearson’s correlations coefficients demonstrate that there are good correlational relationships within each specialization. The ratings of Psychology (PS students reveal higher mean values and lower scattering of Standard Deviations in Moodle tasks than the ratings of Internet Management and Communication (IMC students.Research limitations. The investigated samples contain the limited number of respondents, which might raise a question of the reliability of the findings. The statistical computation of the reliability of the obtained responses will prove whether the data are reliable and may be extended beyond the studied samples.The hypothesis for the research: students’ performance might depend on their specialization. Practical implications. The respondents were asked to indicate the degree of difficulty in performing various online tasks on the Likert’s scale ranging from “very difficult” to “very easy”. The analysis of the responses by a means of the Statistical Package for the Social Sciences (SPSS software proves that despite the limited number of the respondents, the results may be extended beyond the studied samples. It means that self-evaluation of computerized activities by students studying professional English is recommended at the university level.Originality/Value. The value of this study encompasses the statistical processing of the responses, which should prove whether the findings are reliable or not.Research type: research paper.

A Postcolonial Reading of Jamaica Kincaid's The Autobiography Of My Mother

Directory of Open Access Journals (Sweden)

Bahee Hadaegh

2015-10-01

Full Text Available Caribbean literature exposes a history of dispossession, exploitation and oppression which has been neglected and often deliberately misinterpreted. In this article the destructive effects of colonization and slavery in Jamaica Kincaid's 1996 novel The Autobiography of My Mother are scrutinized thoroughly. The main objective of this research is to examine Kincaid's novel within the framework of postcolonial studies, in the light of Albert Memmi (2013 and Frantz Fanon's (2008 theories on the psychology of colonialism. Frantz Fanon argues that colonialism had brought together two opposing social orders doomed to coexist in everlasting tension; the colonizer's and the colonized's; these tensions cause the moral and spiritual deformity of an ideological system based on racism, oppression, and exploitation. In contrast to Fanon, Kincaid regards resistance and liberation in a quite different perspective. Instead of attempting to build a "new woman", Xuela refuses to accept the colonizer's views of those like her that lead to self-destruction and self-hatred. Instead, in order to survive, she confidently chooses self-love, albeit an almost grotesque and obsessive one. Kincaid uses Xuela's relationships with various characters to categorize the social types that Fanon describes in his writings—from Philip and his wife Moira as examples of the deformation of behavior caused by colonial social hierarchies to using mask as a metaphor for her manipulative father's mimicry of the oppressors. This research finds out that colonization and slavery have negative impact on both the colonizer and the colonized.

2016-08-01

The objective of this article is to develop a computerised tool (software) that facilitates the analysis of strategies for waste management on construction sites through the use of indicators of construction and demolition waste generation. The development involved the following steps: knowledge acquisition, structuring the system, coding and system evaluation. The step of knowledge acquisition aims to provide subsidies for the representation of them through models. In the step of structuring the system, it was presented the structuring and formalisation of knowledge for the development of the system, and has two stages: the construction of the conceptual model and the subsequent instantiation of the model. The coding system aims to implement (code) the conceptual model developed in a model played by computer (digital). The results showed that the system is very useful and applicable in construction sites, helping to improve the quality of waste management, and creating a database that will support new research. © The Author(s) 2016.

Buck, J.D. [Kepner-Tregoe (United Kingdom) Ltd., Windsor

1999-08-01

An European Union consultancy project was undertaken to install a `best-in-class` maintenance system for the lignite mines of Romania. The project, funded by PHARE, started with a critical analysis of the maintenance and repair systems of equipment in both the open-pit and underground mines operated by RALO (Regia Autonoma a Lignitului Octenia). This study paved the way for the introduction of a computerised maintenance system and the inception of a planned preventative maintenance scheme. A development strategy leading by a structural methodology towards predictive maintenance and total productive maintenance was drawn up and attention was given to multi-skilling, training and further facilitating activities to enable the success of the total productive maintenance strategy. An abridged version of the paper was presented at MAINTE 97, held in Birmingham, UK in 1997. 5 refs., 5 figs., 1 tab.

Davis, G A; Iverson, G L; Guskiewicz, K M; Ptito, A; Johnston, K M

2009-05-01

To review the diagnostic tests and investigations used in the management of sports concussion, in the adult and paediatric populations, to (a) monitor the severity of symptoms and deficits, (b) track recovery and (c) advance knowledge relating to the natural history and neurobiology of the injury. Qualitative literature review of the neuroimaging, balance testing, electrophysiology, blood marker and concussion literature. PubMed and Medline databases were reviewed for investigations used in the management of adult and paediatric concussion, including structural imaging (computerised tomography, magnetic resonance imaging, diffusion tensor imaging), functional imaging (single photon emission computerised tomography, positron emission tomography, functional magnetic resonance imaging), spectroscopy (magnetic resonance spectroscopy, near infrared spectroscopy), balance testing (Balance Error Scoring System, Sensory Organization Test, gait testing, virtual reality), electrophysiological tests (electroencephalography, evoked potentials, event related potentials, magnetoencephalography, heart rate variability), genetics (apolipoprotein E4, channelopathies) and blood markers (S100, neuron-specific enolase, cleaved Tau protein, glutamate). For the adult and paediatric populations, each test has been classified as being: (1) clinically useful, (2) a research tool only or (3) not useful in sports-related concussion. The current status of the diagnostic tests and investigations is analysed, and potential directions for future research are provided. Currently, all tests and investigations, with the exception of clinical balance testing, remain experimental. There is accumulating research, however, that shows promise for the future clinical application of functional magnetic resonance imaging in sport concussion assessment and management.

Basic ICT adoption and use by general practitioners: an analysis of primary care systems in 31 European countries.

Science.gov (United States)

De Rosis, Sabina; Seghieri, Chiara

2015-08-22

There is general consensus that appropriate development and use of information and communication technologies (ICT) are crucial in the delivery of effective primary care (PC). Several countries are defining policies to support and promote a structural change of the health care system through the introduction of ICT. This study analyses the state of development of basic ICT in PC systems of 31 European countries with the aim to describe the extent of, and main purposes for, computer use by General Practitioners (GPs) across Europe. Additionally, trends over time have been analysed. Descriptive statistical analysis was performed on data from the QUALICOPC (Quality and Costs of Primary Care in Europe) survey, to describe the geographic differences in the general use of computer, and in specific computerized clinical functions for different health-related purposes such as prescribing, medication checking, generating health records and research for medical information on the Internet. While all the countries have achieved a near-universal adoption of a computer in their primary care practices, with only a few countries near or under the boundary of 90 %, the computerisation of primary care clinical functions presents a wide variability of adoption within and among countries and, in several cases (such as in the southern and central-eastern Europe), a large room for improvement. At European level, more efforts could be done to support southern and central-eastern Europe in closing the gap in adoption and use of ICT in PC. In particular, more attention seems to be need on the current usages of the computer in PC, by focusing policies and actions on the improvement of the appropriate usages that can impact on quality and costs of PC and can facilitate an interconnected health care system. However, policies and investments seem necessary but not sufficient to achieve these goals. Organizational, behavioural and also networking aspects should be taken in consideration.

Constraints on property rating in the Offinso South Municipality of Ghana

Directory of Open Access Journals (Sweden)

Nicholas Addai Boamah

2013-12-01

Full Text Available The potential of property rate has been least tapped by decentralized governments in Ghana. This paper investigates the property rating system in Ghana through a case study of Offinso South Municipality (OSM. Questionnaires were used to gather empirical data from property owners in the municipality. The paper finds that there is inadequate property tax administration system and high public disdain for the property tax in OSM, with a significant association between compliance with the property tax and land use regulations in OSM. The paper suggests that the Offinso South Municipal Assembly (OSMA should improve its land use planning system to facilitate voluntary compliance with the property tax. OSMA should also address accountability and transparency problems in the property tax system in order to increase public confidence in the tax regime. The OSMA should also improve on the property tax collection modes by computerising the billing and collection processes.

Cops, Computers and the Right to Privacy in the Information Age: unauthorised access and inapropriate disclosure of information complaints in New South Wales

Directory of Open Access Journals (Sweden)

Mike Enders

2001-05-01

Full Text Available The term the 'information age' is particularly applicable to Australia. In a recent email, the Australian Institute of Criminology's Chief Librarian, John Myrtle, passed on statistics which showed that internet use and access in Australia has increased about 50% during the last year (Pers. Comm. 14 July 1999. Of greater interest is the fact that almost 20% of Australian households, 1.3 million, have internet access and over one third of the adult population has accessed the internet at some time during the year ending February 1999. To further back these figures, the Sydney Morning Herald of 12 February, 2000, carried statistics from the Australian Bureau of Statistics which showed that 22.6% of Australian families had home internet access (Anon., 2000a, p. 105. These figures firmly place Australians among the world's most computer literate societies. Of course computers weren't always that popular. The authors of this paper entered law enforcement at a time when computers were owned by Universities and major corporations - not individuals - and a decent calculator cost about a week's wages. However, things changed quickly and by the 1980s computers were an established part of policing. Today, all major police services are committed to, and reliant on, some form of computerised information system. The two systems which the authors have had contact with are the Crime Reporting and Information System for Police (CRISP (Queensland Police Service and the Computerised Operational Policing System (COPS (New South Wales Police Service. While many aspects of these two systems are different, they, and all the other police information systems in existence, share one major similarity: they store and provide access to personal and confidential information on every individual with whom police come into contact during their duties. Modern police investigation techniques rely on officers being able to access this information routinely to carry out their duties

2009-01-01

NUMO (Nuclear Waste Management Organization of Japan) has the responsibility for implementing deep geological disposal of high-level (HLW) and transuranic (TRU) radioactive waste from the Japanese nuclear programme. A formal Requirements Management System (RMS) is planned to efficiently and effectively support the computerised implementation of the management strategy and the methodology required to drive the step-wise siting processes, and the following repository operational phase,. The RMS will help in the comprehensive management of the decision-making processes in the geological disposal project, in change management as the disposal system is optimised, in driving projects such as the R and D programme efficiently, and in maintaining structured records regarding past decisions, all of which lead to soundness of the project in terms of long-term continuity. The system is planned to have information handling and management functions using a database that includes the decisions/requirements in the programme under consideration, the way in which these are structured in terms of the decision-making process and other associated information. A two-year development programme is underway to develop and enhance an existing trial RMS to a practical system. Functions for change management, history management and association with the external timeline management system are being implemented in the system development work. The database format is being improved to accommodate the requirements management data relating to the facility design and to safety assessment of the deep geological repository. This paper will present an outline of the development work with examples to demonstrate the system's practicality. In parallel with the system/database developments, a case research of the use of requirements management in radioactive waste disposal projects was undertaken to identify key issues in the development of an RMS for radioactive waste disposal and specify a number of

Post-marketing surveillance of quinolones 1988-1990.

Science.gov (United States)

Davey, P G; McDonald, T; Lindsay, G

1991-04-01

It has been much easier to obtain original data on adverse drug reactions (ADR) of quinolones from the pharmaceutical industry than it was two years ago. This is to be welcomed and, as anticipated, the new data continue to suggest that the new 4-quinolones have an ADR profile which is very similar to that of other antimicrobials. Visual disturbance is not a prominent feature, in contrast to the ADR profile of nalidixic acid. Better definition of quinolone ADRs requires prospective study, and the results of a newly completed prescription event monitoring study are awaited with interest. The potential use of computerised databases and record linkage is examined, but at present the number of quinolone prescriptions is too small to assess documentation of serious but rare events such as convulsions. Physicians need to be aware of the limitations of current data on suspected ADRs. Further investment in computerised databases is required to satisfy the requirements for attributing causality of an event to a drug.

An electrical predictive maintenance plan is currently being put into effect at Trillo I Nuclear Power Plant which is initially being applied to three types of equipment: motors, transformers and motor-driven valves. This paper describes the different phases considered in the implementation of the Predictive Maintenance Plan: study of existing techniques for such equipment (tangoδ, spectral analysis of stator current, chromatographic analysis of gases, spectral analysis of the axial stray magnetic flux, etc), study of the special characteristics of the electrical equipment at Trillo NPP, analysis of applicable techniques (characteristic parameters, alert-alarm values, experience with such techniques, etc), analysis of machine history records, study of the optimum preventive-predictive case, study of applicable frequencies and definition of the computerised predictive maintenance management tool. With the exception of the computerised predictive maintenance management applications which are presently being implemented, all the activities described above have been carried out on the three types of equipment mentioned.

Computer-assisted image processing to detect spores from the fungus Pandora neoaphidis.

Science.gov (United States)

Korsnes, Reinert; Westrum, Karin; Fløistad, Erling; Klingen, Ingeborg

2016-01-01

This contribution demonstrates an example of experimental automatic image analysis to detect spores prepared on microscope slides derived from trapping. The application is to monitor aerial spore counts of the entomopathogenic fungus Pandora neoaphidis which may serve as a biological control agent for aphids. Automatic detection of such spores can therefore play a role in plant protection. The present approach for such detection is a modification of traditional manual microscopy of prepared slides, where autonomous image recording precedes computerised image analysis. The purpose of the present image analysis is to support human visual inspection of imagery data - not to replace it. The workflow has three components:•Preparation of slides for microscopy.•Image recording.•Computerised image processing where the initial part is, as usual, segmentation depending on the actual data product. Then comes identification of blobs, calculation of principal axes of blobs, symmetry operations and projection on a three parameter egg shape space.

Mechanisation and automation technologies development in work at construction sites

Science.gov (United States)

Sobotka, A.; Pacewicz, K.

2017-10-01

Implementing construction work that creates buildings is a very complicated and laborious task and requires the use of various types of machines and equipment. For years there has been a desire for designers and technologists to introduce devices that replace people’s work on machine construction, automation and even robots. Technologies for building construction are still being developed and implemented to limit people’s hard work and improve work efficiency and quality in innovative architectonical and construction solutions. New opportunities for improving work on the construction site include computerisation of technological processes and construction management for projects and processes. The aim of the paper was to analyse the development of mechanisation, automation and computerisation of construction processes and selected building technologies, with special attention paid to 3D printing technology. The state of mechanisation of construction works in Poland and trends in its development in construction technologies are presented. These studies were conducted on the basis of the available literature and a survey of Polish construction companies.

The interview-administered 24 h dietary recall (24-HDR) EPIC-Soft® has a series of controls to guarantee the quality of dietary data across countries. These comprise all steps that are part of fieldwork preparation, data collection and data management; however, a complete characterisation of these quality controls is still lacking. The present paper describes in detail the quality controls applied in EPIC-Soft, which are, to a large extent, built on the basis of the EPIC-Soft error model and are present in three phases: (1) before, (2) during and (3) after the 24-HDR interviews. Quality controls for consistency and harmonisation are implemented before the interviews while preparing the seventy databases constituting an EPIC-Soft version (e.g. pre-defined and coded foods and recipes). During the interviews, EPIC-Soft uses a cognitive approach by helping the respondent to recall the dietary intake information in a stepwise manner and includes controls for consistency (e.g. probing questions) as well as for completeness of the collected data (e.g. system calculation for some unknown amounts). After the interviews, a series of controls can be applied by dietitians and data managers to further guarantee data quality. For example, the interview-specific 'note files' that were created to track any problems or missing information during the interviews can be checked to clarify the information initially provided. Overall, the quality controls employed in the EPIC-Soft methodology are not always perceivable, but prove to be of assistance for its overall standardisation and possibly for the accuracy of the collected data.

Computer Security: your car, my control

2015-01-01

We have discussed the Internet of Things (IoT) and its security implications already in past issues of the CERN Bulletin, for example in “Today’s paranoia, tomorrow’s reality” (see here). Unfortunately, tomorrow has come. At this years's Black Hat conference researchers presented their findings on how easily your car can be hacked and controlled remotely. Sigh.   While these researchers have just shown that they can wirelessly hijack a Jeep Cherokee, others have performed similar studies with SmartCars, Fords, a Tesla, a Corvette, BMWs, Chryslers and Mercedes! With the increasing computerisation of cars, the engine management system, air conditioning, anti-lock braking system, electronic stability programme, etc. are linked to the infotainment, navigation and communication systems, opening the door for these vehicles to be hacked remotely. The now prevalent Bluetooth connection with smartphones is one entry vector to attack your car remotely...

Software Support for Industrial Controls Contract

Sánchez-Corral, E

2001-01-01

The contract covers the development and the operation and maintenance (O&M) of the monitoring and control systems used for supervising CERN's technical infrastructure. The contract involves those responsible for equipment in any current or future technical installation. We are outsourcing a complex activity which will require efforts on both preparing the specifications for new projects and setting clear definitions of tasks and procedures for O&M. It is a result-oriented contract in which performance will be continually evaluated by different methods and tools: project management plan and project follow-up, and CAMMS (Computerised Assets and Maintenance Management system). To be used effectively, this approach requires complete traceability of activities and documentation of the systems. Based on the analysis of the results measured and the shared (CERN and contractor) experience, the O&M activities will be reviewed and reorganised and operational procedures will be changed according to needs.

A computer based I and C to improve nuclear power plant operation and safety

International Nuclear Information System (INIS)

Appell, Bernard; Beltranda, Guy

1995-01-01

Chooz B1 is the head of 1400 MW N4 series (up to now, a programme of 4 identical units have been ordered) will be put on the French national grid this year (1995). Hot tests were performed last autumn. Loading fuel is scheduled in June 95. Chooz B2 will follow 6 months later. This nuclear power plant series is fully French designed. It comprises, compared to the former 1300 MW series, evolution concerning mainly the turbine, the steam generators, the primary pumps, the I and C and the man machine interface. A major improvement for the plant operation and safety is the computerised I and C which comprises the protection system (specific controllers), the process automation system (off the shelf equipment), the computer based and conventional man machine interfaces associated. These systems were put in service last year. This paper is focused on them. (author)

Improvements in or relating to radiography

International Nuclear Information System (INIS)

Oldendorf, W.H.

1980-01-01

A method for improving data recording in computerised axial tomography is described in detail. The system allows each visual record to be clearly identified with the relevant slice of the body and also ensures that during a re-examination, the slices investigated can be coincident with the original slices examined. These features are achieved by using an indicator rod or rule which is arranged to measure from an identifiable part of the patient's body, e.g. top of the head or under the arm. The rod itself consists of identifiers (i.e. differing X-ray absorption coefficients), and since the body and rod are examined together, an indelible record of the location of the slice is obtained.

2013-05-01

Several changes have occurred in Olympic boxing (OB) in the last few decades, influencing the results in official competitions. The aim of this study was to assess how the evolution of rules changed the rate of the results that can influence boxers' health. From a web-research, the results of OB tournaments from 1952 to 2011 were reviewed (29,357 bouts). For each event, rate of knockout (KO), referee-stop contest (RSC), RSC-Head (RSCH), RSC-Injury (RSCI), RSC-Outclassed (RSCO), abandon, disqualification and points decisions were recorded. In our analysis we investigated the changes that occurred after the introduction of the standing-count rule (1964), mandatory head guard (1984), computerised scoring system (1992), RSCO (2000-2009) and modification of bout formula 3×3 min rounds (3×3, until 1997, 5×2 min rounds (5×2) until 1999, 4×2 min rounds (4×2) until 2008, 3×3 from 2009). The most important results were: (1) an RSCI rate increase (0.72-2.42%, p<0.03) after the standing-count rule; (2) a lower RSCI (0.60%, p<0.001) and higher RSCH (1.31-4.92%, p<0.001) and RSC (9.71-13.05%, p<0.03) rate with mandatory head guard; (3) a KO rate reduction (6.44-2.09%, p<0.001) with the computerised scoring system; (4) an RSC (13.15-5.91%, p<0.05) and RSCH (4.23-1.41%, p<0.001) rate reduction comparing 5×2-4×2 bouts. In the last six decades, along with rule changes in OB, a clear reduction of health challenging results was observed. In the near future, older rules will be adopted (no head guard and a manual scoring system). Continued medical surveillance is important to ensure that new rule changes do not result in poor medical outcomes for the boxers.

HIF-mediated innate immune responses: cell signaling and therapeutic implications

Full Text Available Alison J Harris, AA Roger Thompson, Moira KB Whyte, Sarah R Walmsley Academic Unit of Respiratory Medicine, Department of Infection and Immunity, University of Sheffield, Sheffield, UK Abstract: Leukocytes recruited to infected, damaged, or inflamed tissues during an immune response must adapt to oxygen levels much lower than those in the circulation. Hypoxia inducible factors (HIFs are key mediators of cellular responses to hypoxia and, as in other cell types, HIFs are critical for the upregulation of glycolysis, which enables innate immune cells to produce adenosine triphosphate anaerobically. An increasing body of evidence demonstrates that hypoxia also regulates many other innate immunological functions, including cell migration, apoptosis, phagocytosis of pathogens, antigen presentation and production of cytokines, chemokines, and angiogenic and antimicrobial factors. Many of these functions are mediated by HIFs, which are not only stabilized posttranslationally by hypoxia, but also transcriptionally upregulated by inflammatory signals. Here, we review the role of HIFs in the responses of innate immune cells to hypoxia, both in vitro and in vivo, with a particular focus on myeloid cells, on which the majority of studies have so far been carried out.

Transforming dose management techniques through technology

International Nuclear Information System (INIS)

Bennett, M.

1995-01-01

The management of occupational dose exposure has been transformed in recent years though the use of facilities such as computerised databases, remote instrumentation and electronic data transfer. Use of this technology has allowed increases both in the amount of data capable of being processed and in the speed at which the data is made available to operators and Health Physics personnel. The dose management system being used in support of the UK's naval nuclear plants has incorporated advances in the areas of dosimetry, data handling and data analysis. Physical dispersion of sites servicing the nuclear plants means that effective communication links have also been vital for good dose management. This paper focuses on some of the most recent dose management technology - the use of virtual reality models linked with a predictive computer code for work planning, a remote area monitoring system with diagnostic software, a personnel dosimetry telemetry system, and electronically linked computer databases.

Estimation of cortical silent period following transcranial magnetic stimulation using a computerised cumulative sum method.

Science.gov (United States)

King, Nicolas K K; Kuppuswamy, Annapoorna; Strutton, Paul H; Davey, Nick J

2006-01-15

The cortical silent period (CSP) following transcranial magnetic stimulation (TMS) of the motor cortex can be used to measure intra-cortical inhibition and changes in a number of important pathologies affecting the central nervous system. The main drawback of this technique has been the difficulty in accurately identifying the onset and offset of the cortical silent period leading to inter-observer variability. We developed an automated method based on the cumulative sum (Cusum) technique to improve the determination of the duration and area of the cortical silent period. This was compared with experienced raters and two other automated methods. We showed that the automated Cusum method reliably correlated with the experienced raters for both duration and area of CSP. Compared with the automated methods, the Cusum also showed the strongest correlation with the experienced raters. Our results show the Cusum method to be a simple, graphical and powerful method of detecting low-intensity CSP that can be easily automated using standard software.

Computerization of guidelines: towards a "guideline markup language".

Science.gov (United States)

Dart, T; Xu, Y; Chatellier, G; Degoulet, P

2001-01-01

Medical decision making is one of the most difficult daily tasks for physicians. Guidelines have been designed to reduce variance between physicians in daily practice, to improve patient outcomes and to control costs. In fact, few physicians use guidelines in daily practice. A way to ease the use of guidelines is to implement computerised guidelines (computer reminders). We present in this paper a method of computerising guidelines. Our objectives were: 1) to propose a generic model that can be instantiated for any specific guidelines; 2) to use eXtensible Markup Language (XML) as a guideline representation language to instantiate the generic model for a specific guideline. Our model is an object representation of a clinical algorithm, it has been validated by running two different guidelines issued by a French official Agency. In spite of some limitations, we found that this model is expressive enough to represent complex guidelines devoted to diabetes and hypertension management. We conclude that XML can be used as a description format to structure guidelines and as an interface between paper-based guidelines and computer applications.

This paper presents the simulation tool called SDDRIVE (Simple Simulation of Driver performance), which is the numerical computerised implementation of the theoretical architecture describing Driver-Vehicle-Environment (DVE) interactions, contained in Cacciabue and Carsten [Cacciabue, P.C., Carsten, O. A simple model of driver behaviour to sustain design and safety assessment of automated systems in automotive environments, 2010]. Following a brief description of the basic algorithms that simulate the performance of drivers, the paper presents and discusses a set of experiments carried out in a Virtual Reality full scale simulator for validating the simulation. Then the predictive potentiality of the tool is shown by discussing two case studies of DVE interactions, performed in the presence of different driver attitudes in similar traffic conditions.

Computerisation of general practice in the Republic of Croatia: experience gained in general practice use

Full Text Available Well-organised medical records are the prerequisite for achieving a high level of performance in primary healthcare settings. Recording balanced structured and coded data as well as free text can improve both quality and organisation of work in the office. It provides a more substantiated support of financial transactions and accountancy, allows better communication with other facilities and institutions, and is a source of valuable scientific research material. This article is the result of an individual experience gained in general practice use of various programs/ systems employed within the family medicine frame, and the frame of evaluation of available and commonly- exploited program solutions. The use of various programs allows for systematic adjustments as to the increasingly complex requirements imposed on electronic medical records (EMRs. The experience of a general practitioner, presented in this paper, confirms the assumption that an adequate program to be employed with EMRs should be developed, provided that family medicine practitioners, that is, the final users, have been involved in each and every stage of its development, adjustment, implementation and evaluation.

SeeSway - A free web-based system for analysing and exploring standing balance data.

Science.gov (United States)

Clark, Ross A; Pua, Yong-Hao

2018-06-01

Computerised posturography can be used to assess standing balance, and can predict poor functional outcomes in many clinical populations. A key limitation is the disparate signal filtering and analysis techniques, with many methods requiring custom computer programs. This paper discusses the creation of a freely available web-based software program, SeeSway (www.rehabtools.org/seesway), which was designed to provide powerful tools for pre-processing, analysing and visualising standing balance data in an easy to use and platform independent website. SeeSway links an interactive web platform with file upload capability to software systems including LabVIEW, Matlab, Python and R to perform the data filtering, analysis and visualisation of standing balance data. Input data can consist of any signal that comprises an anterior-posterior and medial-lateral coordinate trace such as center of pressure or mass displacement. This allows it to be used with systems including criterion reference commercial force platforms and three dimensional motion analysis, smartphones, accelerometers and low-cost technology such as Nintendo Wii Balance Board and Microsoft Kinect. Filtering options include Butterworth, weighted and unweighted moving average, and discrete wavelet transforms. Analysis methods include standard techniques such as path length, amplitude, and root mean square in addition to less common but potentially promising methods such as sample entropy, detrended fluctuation analysis and multiresolution wavelet analysis. These data are visualised using scalograms, which chart the change in frequency content over time, scatterplots and standard line charts. This provides the user with a detailed understanding of their results, and how their different pre-processing and analysis method selections affect their findings. An example of the data analysis techniques is provided in the paper, with graphical representation of how advanced analysis methods can better discriminate

Biobehavioural analysis of the vestibular system and posture control in patients with cervicogenic dizziness. A cross-sectional study.

Science.gov (United States)

Grande-Alonso, M; Moral Saiz, B; Mínguez Zuazo, A; Lerma Lara, S; La Touche, R

2018-03-01

Cervicogenic dizziness is a musculoskeletal disorder mainly characterised by dizziness and disequilibrium associated with neck pain. The pathophysiology is unclear and the neurophysiological basis remains to be ascertained. The aim of this study is to compare the vestibulo-ocular reflex and postural control between patients with cervicogenic dizziness and asymptomatic subjects, and to assess the association between debilitating dizziness and other psychosocial variables. A total of 20 patients and 22 asymptomatic subjects were selected. Vestibulo-ocular reflex was assessed by performing the head impulse test. Computerised dynamic posturography was used to evaluate the postural control by means of the sensory organisation test. In addition, subjects self-reported their degree of disability due to dizziness, cervical disability, kinesiophobia, and state of anxiety and depression. There were no differences in the vestibulo-ocular reflex (P>.05). However, we found differences with a medium-to-large effect size (d>0.60) in variables related to proprioception and visual information integration; the former variable set was related to disability due to dizziness. Disability due to dizziness presents strong-to-moderate associations with cervical disability, kinesiophobia, and anxiety. Our data rule out changes in the vestibular system in cervicogenic dizziness, but they do point to proprioceptive impairment. According to our results, the association between dizziness-related disability and other psychosocial factors in cervicogenic dizziness is very relevant for clinical medicine and for future research projects.

2002-03-01

Full Text Available The publication Information for Health provided a detailed exposition of the government's requirements for modernising the NHS from an information point of view.1 Furthermore, it described how information technology (IT can be harnessed to support the process of patient care, involving the use of both the Electronic Patient Record (EPR and Electronic Health Record (EHR. However, it is widely recognised that clinical computer systems in primary care are dramatically underutilised, and computerised patient records are of variable quality and reliability. One important factor has been the lack of training and support available to ensure greater use of IT (i.e. the clinical computer systems. Steps are being taken in Teesside to address this problem; the prime objective of which is to support practices to make greater use of their IT investment, and with particular reference to the national service framework (NSF on coronary heart disease (CHD.2

Collection of offshore human error probability data

Basra, Gurpreet; Kirwan, Barry

1998-01-01

Accidents such as Piper Alpha have increased concern about the effects of human errors in complex systems. Such accidents can in theory be predicted and prevented by risk assessment, and in particular human reliability assessment (HRA), but HRA ideally requires qualitative and quantitative human error data. A research initiative at the University of Birmingham led to the development of CORE-DATA, a Computerised Human Error Data Base. This system currently contains a reasonably large number of human error data points, collected from a variety of mainly nuclear-power related sources. This article outlines a recent offshore data collection study, concerned with collecting lifeboat evacuation data. Data collection methods are outlined and a selection of human error probabilities generated as a result of the study are provided. These data give insights into the type of errors and human failure rates that could be utilised to support offshore risk analyses

A nuclear reactor is a complex process plant. Like a nuclear power plant, the research reactors also employ various nuclear and process systems, the scope and number of such systems being plant-specific. In-service inspection of these systems is an important requirement and is applied at various levels of their constituent units such as detectors, electronics components, circuits and integrated systems. The sensors used cover a wide range such as neutronic, radiation, process (pressure, temperature, flow, level) and many others. The present discussion is limited to neutronic and radiation detectors. The electronic components used normally consist of passive components like resistors, capacitors, semiconductor components like diodes, transistors, analog integrated circuits and digital integrated circuits and electromagnetic relays, to name a few. In order to have a comprehensive surveillance and ISI plan, over the entire plant life, it is necessary to understand various mechanisms, which degrade the performance of these systems. These are discussed initially and later various ISI methods that are used on component-circuit or system level, to ensure optimum system performance, are discussed. The computerised systems, because of hardware and software considerations, have to be given special attention, and the same are discussed briefly

Objective: To investigate the validity and reliability of computerised acoustic analysis in the detection of abnormal respiratory noises in infants. Methods: Blinded, prospective comparison of acoustic analysis with stethoscope examination. Validity and reliability of acoustic analysis were assessed by calculating the degree of observer agreement using the κ statistic with 95% confidence intervals (CI). Results: 102 infants under 18 months were recruited. Convergent validity for agreement between stethoscope examination and acoustic analysis was poor for wheeze (κ = 0.07 (95% CI, –0.13 to 0.26)) and rattles (κ = 0.11 (–0.05 to 0.27)) and fair for crackles (κ = 0.36 (0.18 to 0.54)). Both the stethoscope and acoustic analysis distinguished well between sounds (discriminant validity). Agreement between observers for the presence of wheeze was poor for both stethoscope examination and acoustic analysis. Agreement for rattles was moderate for the stethoscope but poor for acoustic analysis. Agreement for crackles was moderate using both techniques. Within-observer reliability for all sounds using acoustic analysis was moderate to good. Conclusions: The stethoscope is unreliable for assessing respiratory sounds in infants. This has important implications for its use as a diagnostic tool for lung disorders in infants, and confirms that it cannot be used as a gold standard. Because of the unreliability of the stethoscope, the validity of acoustic analysis could not be demonstrated, although it could discriminate between sounds well and showed good within-observer reliability. For acoustic analysis, targeted training and the development of computerised pattern recognition systems may improve reliability so that it can be used in clinical practice. PMID:15499065

Detecting communicative intent in a computerised test of joint attention

Directory of Open Access Journals (Sweden)

Nathan Caruana

2017-01-01

Full Text Available The successful navigation of social interactions depends on a range of cognitive faculties—including the ability to achieve joint attention with others to share information and experiences. We investigated the influence that intention monitoring processes have on gaze-following response times during joint attention. We employed a virtual reality task in which 16 healthy adults engaged in a collaborative game with a virtual partner to locate a target in a visual array. In the Search task, the virtual partner was programmed to engage in non-communicative gaze shifts in search of the target, establish eye contact, and then display a communicative gaze shift to guide the participant to the target. In the NoSearch task, the virtual partner simply established eye contact and then made a single communicative gaze shift towards the target (i.e., there were no non-communicative gaze shifts in search of the target. Thus, only the Search task required participants to monitor their partner’s communicative intent before responding to joint attention bids. We found that gaze following was significantly slower in the Search task than the NoSearch task. However, the same effect on response times was not observed when participants completed non-social control versions of the Search and NoSearch tasks, in which the avatar’s gaze was replaced by arrow cues. These data demonstrate that the intention monitoring processes involved in differentiating communicative and non-communicative gaze shifts during the Search task had a measurable influence on subsequent joint attention behaviour. The empirical and methodological implications of these findings for the fields of autism and social neuroscience will be discussed.

1979-01-01

A previously published age-diffusion model has been adapted to obtain parameters for the Saggittaire linear accelerator electron beams. The calculations are shown and the results discussed. A comparison is presented between measured and predicted percentage depth doses for electron beams at various energies between 10 and 32 MeV. Theoretical isodose curves are compared, for an energy of 10 MeV, with experimental curves. The parameters obtained are used for computer electron isodose curve calculation in a program called FIJOE adapted from a previously published program. This program makes it possible to correct for irregular body contours, but not for internal inhomogeneities. (UK)

Application of near real time accountancy to nuclear material balance data

International Nuclear Information System (INIS)

Seifert, R.

1990-02-01

The application of near real time accountancy to nuclear material balance data can be performed effectively only with the help of computerised nuclear material accounting and information systems. Two computer programmes are introduced: DIDI, a programme for computing the MUF series and the measurement model of a reprocessing plant which is assumed to be a one-block model from data resulting from the routine operation of the facility, and PROSA, a programme for statistical analysis of NRTA data, which evaluates the MUF series on the basis of the measurement model. After the presentation of the two computer programmes two examples with realistic balance data will demonstrate the application of NRTA measures. Furthermore, some new remarks on the precision of Monte-Carlo simulations are mentioned which provide a substantial better estimation. (orig.) [de

The aim of this retrospective study was to investigate the use of thoracic Computed Tomography (CT) in the Emergency Department of a Dublin Academic Teaching Hospital over a six month period. Data was retrieved using the hospital\\'s computerised information system. There were 202 referrals in total for thoracic CT from the Emergency Department during this time period. The most common indication for thoracic CT referral was for the investigation of pulmonary embolism with 127 (63%) referrals. There were 40 (25%) referrals for suspected malignancy and lung disease, whilst 8 (4%) of the referrals were for investigation of thoracic aortic dissection, 8 (4%) for infection, and 6 (3%) were for investigation of thoracic injury. Only 8 (4%) of all referrals were for investigation of injury as a result of chest trauma.

van Staden, J Koos F; Mashamba, M Mulalo G; Stefan, R Raluca I

2002-12-06

A potentiometric SI titration system for the determination of total acidity in soft drinks is proposed. The concept is based on the aspiration of the acid soft drink sample between two base zones into a holding coil with the volume of the first base zone twice to that of the second one and channelled by flow reversal through a reaction coil to a potentiometric sensor. A solution of 0.1 mol l(-1) sodium chloride is used as ionic strength adjustment buffer in the carrier stream. The system has been applied to the analysis of some South African soft drinks having a total acidity level of about 0.2-0.3% (w/v). The method has a sample frequency of 45 samples per h with a linear range of 0.1 and 0.6% (w/v). It is easy to use, fully computerised, and gives the results that are comparable to both automated batch titration and manual titration.

Tuberculosis (TB) screening programmes can be optimised by reducing the number of chest radiographs (CXRs) requiring interpretation by human experts. To evaluate the performance of computerised detection software in triaging CXRs in a high-throughput digital mobile TB screening programme. A retrospective evaluation of the software was performed on a database of 38 961 postero-anterior CXRs from unique individuals seen between 2005 and 2010, 87 of whom were diagnosed with TB. The software generated a TB likelihood score for each CXR. This score was compared with a reference standard for notified active pulmonary TB using receiver operating characteristic (ROC) curve and localisation ROC (LROC) curve analyses. On ROC curve analysis, software specificity was 55.71% (95%CI 55.21-56.20) and negative predictive value was 99.98% (95%CI 99.95-99.99), at a sensitivity of 95%. The area under the ROC curve was 0.90 (95%CI 0.86-0.93). Results of the LROC curve analysis were similar. The software could identify more than half of the normal images in a TB screening setting while maintaining high sensitivity, and may therefore be used for triage.

A body of literature shows the significant role of visual-spatial skills played in the improvement of mathematical skills in the primary school. The main goal of the current study was to investigate the impact of a combined visuo-spatial and mathematical training on the improvement of mathematical skills in 146 second graders of several schools located in Italy. Participants were presented single pencil-and-paper visuo-spatial or mathematical trainings, computerised version of the above mentioned treatments, as well as a combined version of computer-assisted and pencil-and-paper visuo-spatial and mathematical trainings, respectively. Experimental groups were presented with training for 3 months, once a week. All children were treated collectively both in computer-assisted or pencil-and-paper modalities. At pre and post-test all our participants were presented with a battery of objective tests assessing numerical and visuo-spatial abilities. Our results suggest the positive effect of different types of training for the empowerment of visuo-spatial and numerical abilities. Specifically, the combination of computerised and pencil-and-paper versions of visuo-spatial and mathematical trainings are more effective than the single execution of the software or of the pencil-and-paper treatment

New approaches to evaluating fault trees

International Nuclear Information System (INIS)

Sinnamon, R.M.; Andrews, J.D.

1997-01-01

Fault Tree Analysis is now a widely accepted technique to assess the probability and frequency of system failure in many industries. For complex systems an analysis may produce hundreds of thousands of combinations of events which can cause system failure (minimal cut sets). The determination of these cut sets can be a very time consuming process even on modern high speed digital computers. Computerised methods, such as bottom-up or top-down approaches, to conduct this analysis are now so well developed that further refinement is unlikely to result in vast reductions in computer time. It is felt that substantial improvement in computer utilisation will only result from a completely new approach. This paper describes the use of a Binary Decision Diagram for Fault Tree Analysis and some ways in which it can be efficiently implemented on a computer. In particular, attention is given to the production of a minimum form of the Binary Decision Diagram by considering the ordering that has to be given to the basic events of the fault tree

The osseous manifestations of osteochondrosis dissecans are well demonstrated by conventional and computerised tomography. Beyond that, magnetic resonance imaging (MRI) is effective in evaluating the vitality and loosening of an osseous dissecate. Subchondral cavities and cartilaginous defects are detected with high acccuracy. Further, MRI seems to be a useful method in childhood to differentiate a variant irregularity of the osseous articular surface from definite osteochondrosis dissecans.

Computer aided method for colour calibration and analysis of digital rock photographs

Directory of Open Access Journals (Sweden)

Matic Potočnik

2015-12-01

Full Text Available The methods used in geology to determine colour and colour coverage are expensive, time consuming, and/ or subjective. Estimates of colour coverage can only be approximate since they are based on rough comparisonbased measuring etalons and subjective estimation, which is dependent upon the skill and experience of the person performing the estimation. We present a method which accelerates, simplifis, and objectifis these tasks using a computer application. It automatically calibrates the colours of a digital photo, and enables the user to read colour values and coverage, even after returning from fild work. Colour identifiation is based on the Munsell colour system. For the purposes of colour calibration we use the X-Rite ColorChecker Passport colour chart placed onto the photographed scene. Our computer application detects the ColorChecker colour chart, and fids a colour space transformation to calibrate the colour in the photo. The user can then use the application to read colours within selected points or regions of the photo. The results of the computerised colour calibration were compared to the reference values of the ColorChecker chart. The values slightly deviate from the exact values, but the deviation is around the limit of human capability for visual comparison. We have devised an experiment, which compares the precision of the computerised colour analysis and manual colour analysis performed on a variety of rock samples with the help of geology students using Munsell Rock-color Chart. The analysis showed that the precision of manual comparative identifiation on multicoloured samples is somewhat problematic, since the choice of representative colours and observation points for a certain part of a sample are subjective. The computer based method has the edge in verifibility and repeatability of the analysis since the application the original photo to be saved with colour calibration, and tagging of colouranalysed points and regions.

Ergonomic requirements on computer-based information- and handling engineering in nuclear power plants

International Nuclear Information System (INIS)

Fassmann, W.

2002-01-01

This project provides regulatory authorities with a set of criteria for evaluating hybrid man-machine interfaces in nuclear power plant control rooms from a human factors point of view. Such standards are necessary for two reasons: (1) More and more computerised information and control systems have been and will be introduced in nuclear power plant control rooms. One possible result of this trend will be the creation of hybrid man machine interfaces which will provide both conventional and computer-based display and control devices. (2) Available rules and regulations do not contain detailed requirements on how to integrate both types of interface in such a way that plant operation by means of hybrid interfaces will be performed at least as reliably and safely as by means of conventional ones. To fill this gap, criteria and methods were developed which support practical checks of requirements to be applied to hybrid control rooms. This approach is based on state of the art methods and criteria in ergonomics. It makes it possible to analyse and to describe personnel's actions in a consistent and structured way in order to provide the information which is necessary for evaluating human reliability of task performance. Reliability can be evaluated with respect to - accuracy of required information on displays, - networking of tasks, - possibilities of interrupting and cancelling measures which have already been initiated, - possibility to carry out required manuel actions, - level of mental work-strain, - workload level, - probability of erroneous actions. This method is part of a catalogue of recommendations for evaluating hybrid nuclear power plant control rooms. The catalogue also contains recommendations for the design of computerised parts of the man-machine-interface. Application of these design recommendations will help create favourable conditions for an acceptable level of work-strain and for reliable task performance. (orig.) [de

Quantitative assessment of pain-related thermal dysfunction through clinical digital infrared thermal imaging

Directory of Open Access Journals (Sweden)

Frize Monique

2004-06-01

Full Text Available Abstract Background The skin temperature distribution of a healthy human body exhibits a contralateral symmetry. Some nociceptive and most neuropathic pain pathologies are associated with an alteration of the thermal distribution of the human body. Since the dissipation of heat through the skin occurs for the most part in the form of infrared radiation, infrared thermography is the method of choice to study the physiology of thermoregulation and the thermal dysfunction associated with pain. Assessing thermograms is a complex and subjective task that can be greatly facilitated by computerised techniques. Methods This paper presents techniques for automated computerised assessment of thermal images of pain, in order to facilitate the physician's decision making. First, the thermal images are pre-processed to reduce the noise introduced during the initial acquisition and to extract the irrelevant background. Then, potential regions of interest are identified using fixed dermatomal subdivisions of the body, isothermal analysis and segmentation techniques. Finally, we assess the degree of asymmetry between contralateral regions of interest using statistical computations and distance measures between comparable regions. Results The wavelet domain-based Poisson noise removal techniques compared favourably against Wiener and other wavelet-based denoising methods, when qualitative criteria were used. It was shown to improve slightly the subsequent analysis. The automated background removal technique based on thresholding and morphological operations was successful for both noisy and denoised images with a correct removal rate of 85% of the images in the database. The automation of the regions of interest (ROIs delimitation process was achieved successfully for images with a good contralateral symmetry. Isothermal division complemented well the fixed ROIs division based on dermatomes, giving a more accurate map of potentially abnormal regions. The measure

The growing worldwide population has increased the need for technologies, computerised software algorithms and smart devices that can monitor and assist patients anytime and anywhere and thus enable them to lead independent lives. The real-time remote monitoring of patients is an important issue in telemedicine. In the provision of healthcare services, patient prioritisation poses a significant challenge because of the complex decision-making process it involves when patients are considered 'big data'. To our knowledge, no study has highlighted the link between 'big data' characteristics and real-time remote healthcare monitoring in the patient prioritisation process, as well as the inherent challenges involved. Thus, we present comprehensive insights into the elements of big data characteristics according to the six 'Vs': volume, velocity, variety, veracity, value and variability. Each of these elements is presented and connected to a related part in the study of the connection between patient prioritisation and real-time remote healthcare monitoring systems. Then, we determine the weak points and recommend solutions as potential future work. This study makes the following contributions. (1) The link between big data characteristics and real-time remote healthcare monitoring in the patient prioritisation process is described. (2) The open issues and challenges for big data used in the patient prioritisation process are emphasised. (3) As a recommended solution, decision making using multiple criteria, such as vital signs and chief complaints, is utilised to prioritise the big data of patients with chronic diseases on the basis of the most urgent cases.

AFTC Code for Automatic Fault Tree Construction: Users Manual

1999-04-01

Fault Trees perform a predominant role in reliability and safety analysis of system. Manual construction of fault tree is a very time consuming task and moreover, it won't give a formalized result, since it relies highly on analysts experience and heuristics. This necessitates a computerised fault tree construction, which is still attracting interest of reliability analysts. AFTC software is a user friendly software model for constructing fault trees based on decision tables. Software is equipped with libraries of decision tables for components commonly used in various Nuclear Power Plant (NPP) systems. User is expected to make a nodal diagram of the system, for which fault tree is to be constructed, from the flow sheets available. The text nodal diagram goes as the sole input defining the system flow chart. AFTC software is a rule based expert system which draws the fault tree from the system flow chart and component decision tables. AFTC software gives fault tree in both text and graphic format. Help is provided as how to enter system flow chart and component decision tables. The software is developed in 'C' language. Software is verified with simplified version of the fire water system of an Indian PHWR. Code conversion will be undertaken to create a window based version. (author)

Taiwo Adeleke, Ibrahim; Hakeem Lawal, Adedeji; Adetona Adio, Razzaq; Adisa Adebisi, AbdulLateef

There is a lack of effective health information management systems in Nigeria due to the prevalence of cumbersome paper-based and disjointed health data management systems. This can make informed healthcare decision making difficult. This study examined the information technology (IT) skills, utilisation and training needs of Nigerian health information management professionals. We deployed a cross-sectional structured questionnaire to determine the IT skills and training needs of health information management professionals who have leadership roles in the nation's healthcare information systems (n=374). It was found that ownership of a computer, level of education and age were associated with knowledge and perception of IT. The vast majority of participants (98.8%) acknowledged the importance and relevance of IT in healthcare information systems and many expressed a desire for further IT training, especially in statistical analysis. Despite this, few (8.1 %) worked in settings where such systems operate and there exists an IT skill gap among these professionals which is not compatible with their roles in healthcare information systems. To rectify this anomaly they require continuing professional development education, especially in the areas of health IT. Government intervention in the provision of IT infrastructure in order to put into practice a computerised healthcare information system would therefore be a worthwhile undertaking.

The eleven years of operating experience of Caorso NPP supply a consistent and homogeneous data set of events involving safety-related systems and components. The above data, periodically transmitted to the Italian regulatory body (ENEA/DISP) by the utility (ENEL), as required by the italian rules and regulations, are collected into a computerised Data Bank (SEME). A PC software package (TENDA), which uses, as input, the codes from the SEME Data Bank, was set-up inside ENEA/DISP, with the aim to perform automatic Trend and pattern Analysis. Graphic software was also utilized for a more self-explaining presentation of the results. They are being utilized as input for subsequent studies related to other plants (e.g. PRA and living PRA as well). Plans for the utilization of the TENDA program for new plants and in the conventional area are now under consideration

Patient safety is a principal concern for health professionals in the care process and it is, therefore, necessary to provide information management systems to each unit of the hospital, capable of tracking patients and medication to reduce the occurrence of adverse events and therefore increase the quality of care received by patients during their stay in hospital. This work presents a tool for the Intensive Care Unit (ICU), a key service with special characteristics, which computerises and tracks admissions, care plans, vital monitoring, the prescription and medication administration process for patients in this service. To achieve this, it is essential that innovative and cutting-edge technologies are implemented such as Near Field Communication (NFC) technology which is now being implemented in diverse environments bringing a range of benefits to the tasks for which it is employed.

Background: Lower respiratory tract infections (LRTI) are the leading cause of hospital visits in children under 5 years old. Therefore, there is an urgent and unmet need to develop objective, reliable and quick measures for respiratory paediatric assessment. Computerised adventitious respiratory sounds (ARS) have shown to be objective and reliable to assess/monitor respiratory diseases; however its application in children with LRTI is unknown. Aim: To characterise/compare A...

2013-01-01

Cognitive remediation refers to nonpharmacological methods of improving cognitive function in people with severe mental disorders. Cognitive remediation therapy (CRT) can be delivered via computerised programs, of varying length and complexity, or can be undertaken one-on-one by a trained clinician. There has been a considerable interest in cognitive remediation, driven by recognition that cognitive deficits are a major determinant of outcome in people with severe, chronic mental illnesses.

This patent claim, on behalf of E.M.I. Ltd., relates to overcoming the difficulties previously encountered in computerised axial tomography, where the collimator for each detector needs to follow the motion of the source through an appreciable angle, e.g. 40 0 , but the motion of the source, being caused by electronic scanning, is so rapid as to cause difficulties for a mechanical movement imparted to the collimators.

In the UK, colorectal cancer (CRC) is the third most common malignancy (behind lung and breast cancer) with 37,514 cases registered in 2006: around two-thirds (23,384) in the colon and one-third (14,130) in the rectum. Treatment of cancers of the colon can vary considerably, but surgical resection is the mainstay of treatment for curative intent. Following surgical resection, there is a comprehensive assessment of the tumour, it's invasion characteristics and spread (tumour staging). A number of imaging modalities are used in the pre-operative staging of CRCs including; computerised tomography (CT), magnetic resonance imaging, ultrasound imaging and positron emission tomography (PET). This report examines the role of CT in combination with PET scanning (PET/CT 'hybrid' scan). The research objectives are: to evaluate the diagnostic accuracy and therapeutic impact of fluorine-18-deoxyglucose (FDG) PET/CT for the pre-operative staging of primary, recurrent and metastatic cancer using systematic review methods; undertake probabilistic decision-analytic modelling (using Monte Carlo simulation); and conduct a value of information analysis to help inform whether or not there is potential worth in undertaking further research. For each aspect of the research - the systematic review, the handsearch study and the economic evaluation - a database was assembled from a comprehensive search for published and unpublished studies, which included database searches, reference lists search and contact with experts. In the systematic review prospective and retrospective patient series (diagnostic cohort) and randomised controlled trials (RCTs) were eligible for inclusion. Both consecutive series and series that are not explicitly reported as consecutive were included. Two reviewers extracted all data and applied the criteria independently and resolved disagreements by discussion.

2016-04-01

Full Text Available Background Research regarding return on investment for electronic health records (EHRs is sparse. Objective To extend previously established research and examine rigorously whether increasing the adoption of computer-based provider/prescriber order entry (CPOE leads to a decrease in length of stay (LOS, and to demonstrate that the two are inversely and bidirectionally proportional even while other efforts to decrease LOS are in place. Method The study assessed CPOE, LOS and case mix index (CMI data in a community hospital in the United States, using a mature and nearly fully deployed vendor product EHR. CPOE rates and LOS over 7 years were determined on a per-patient, per-visit and per-discipline basis and compared with concomitant CMI data. Results An inverse relationship of CPOE to LOS was correlated for 13 disciplines out of 19, and organisation wide for all disciplines combined during the first 5 years of study. During the subsequent 2 years, both CPOE and LOS plateaued, except in eight disciplines where CPOE rates at first declined and LOS concurrently rose slightly, and then returned to the baseline plateau levels. CMI increased during the entire period of evaluation. An inflection point at approximately 60% CPOE adoption predicted the greatest improvement in lowering of LOS. Conclusions Rising and falling rates of CPOE correlated with reductions and rises in LOS, respectively. CPOE appeared statistically to be an independent factor in affecting LOS, over and above other efforts to shorten LOS, thus contributing to lower costs and improved efficiency outcomes as measured by LOS, even as CMI rises.

EDI is the technique the most frequently used by Chemists to relay their daily orders to their suppliers. Three out of four Chemists in France are computerised using various forms of computer hardware and software. The Health Care organisations propose that Chemists use the EDI to relay to the CETELIC all the items of information concerning their invoicing. This means handing over administrative information identifying the patient, the doctor ... as well as financial and confidential data such as the CIP code of the prescribed and delivered medicine. The law of the 4th January 1993 was instigated to control the rising expenses of the Health Care organisations and it mandates the Caisse Primaire d'Assurance Maladie (the French social security organisations) to retrieve and analyse the information thus gathered from all of the medical professionals involved. However, the accumulation of all these items of computerised information constitutes in effect a confidential medical file on each patient. This raises the following issues: Who does this confidential data belong to? Who should the Chemists give it to? What is to be done with it? Who will be responsible for its analysis in respect of the confidentiality problem? (Another medical professional bound by oath?) And how can we insure against subsequent abuse of this material?

This quasi-experimental study investigated how an intervention aiming at increasing eldercare workers' influence on their working hours affected the flexibility, variability, regularity and predictability of the working hours. We used baseline (n = 296) and follow-up (n = 274) questionnaire data and interviews with intervention-group participants (n = 32). The work units in the intervention group designed their own intervention comprising either implementation of computerised self-scheduling (subgroup A), collection of information about the employees' work-time preferences by questionnaires (subgroup B), or discussion of working hours (subgroup C). Only computerised self-scheduling changed the working hours and the way they were planned. These changes implied more flexible but less regular working hours and an experience of less predictability and less continuity in the care of clients and in the co-operation with colleagues. In subgroup B and C, the participants ended up discussing the potential consequences of more work-time influence without actually implementing any changes. Employee work-time influence may buffer the adverse effects of shift work. However, our intervention study suggested that while increasing the individual flexibility, increasing work-time influence may also result in decreased regularity of the working hours and less continuity in the care of clients and co-operation with colleagues.

Violence in the physical (offline) world is a well-documented health and social issue among young people worldwide. In Southeast Asia, online harassment (defined as intentional behaviours to harm others through the Internet or through mobile devices) is less well documented. In this paper, we describe and critically discuss the mixed-methods data collection approach we used to build a contextualised understanding of offline violence and online harassment among 15-24 year-old students and out-of-school youth in Central Thailand. We mapped linkages between offline violence and online harassment, and with their possible correlates including gender, sexuality, and mobile media or Internet use. Data collection methods included in-depth interviews, focus group discussions and a custom-built, self-administered computerised survey. Using mixed methods enabled us to collect holistic qualitative/quantitative data from both students and out-of-school youth. In our discussion, we focus on gender, sexuality, class and ethnicity issues in recruiting out-of-school youth; definition and measurement issues; technical issues in using a computerised survey; ethical issues surrounding data collection from minors as well as privacy and confidentiality concerns in collecting data in both in-school and out-of-school settings; and the general implications of using mixed methods.

Malone, Ailish

2012-02-01

The aims of this study were to validate a computerised method to detect muscle activity from surface electromyography (SEMG) signals in gait in patients with cervical spondylotic myelopathy (CSM), and to evaluate the test-retest reliability of the activation times designated by this method. SEMG signals were recorded from rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA), and medial gastrocnemius (MG), during gait in 12 participants with CSM on two separate test days. Four computerised activity detection methods, based on the Teager-Kaiser Energy Operator (TKEO), were applied to a subset of signals and compared to visual interpretation of muscle activation. The most accurate method was then applied to all signals for evaluation of test-retest reliability. A detection method based on a combined slope and amplitude threshold showed the highest agreement (87.5%) with visual interpretation. With respect to reliability, the standard error of measurement (SEM) of the timing of RF, TA and MG between test days was 5.5% stride duration or less, while the SEM of BF was 9.4%. The timing parameters of RF, TA and MG designated by this method were considered sufficiently reliable for use in clinical practice, however the reliability of BF was questionable.

design – strengthened by provision of transport for clients to health centres, separate men's and women's clinic rooms, specific roles of primary care team members in relation to chronic illness care, effective teamwork, and functional pathology and pharmacy systems, but weakened by staff shortage (particularly doctors and Aboriginal health workers and high staff turnover; and 6 clinical information systems – facilitated by wide adoption of computerised information systems, but weakened by the systems' complexity and lack of IT maintenance and upgrade support. Conclusion Using concrete examples, this study translates the concept of the Chronic Care Model (and associated systems view into practical application in Australian Indigenous primary care settings. This approach proved to be useful in understanding the quality of primary care systems for prevention and management of chronic illness. Further refinement of the systems should focus on both increasing human and financial resources and improving management practice.

CAMS as a tool for identifying and predicting abnormal plant states using real-time simulation

International Nuclear Information System (INIS)

Fantoni, P.F.; Soerenssen, A.; Meyer, G.

1999-01-01

CAMS (Computerised Accident Management Support) is a system that provides assistance to the staff in a nuclear power plant control room, in the technical support centre and in the national safety centre. Support is offered in identification of the current plant state, in assessment of the future development of the accident and in planning mitigation strategies. CAMS is a modular system, where several modules perform different tasks under the control and supervision of a central knowledge based system, which is responsible of the syncronisation and the flow of information through the activated modules. A CAMS prototype has been tested by the Swedish Nuclear Inspectorate during a safety exercise in Sweden in 1995, with satisfactory results. Future developments include automatic control of the Predictive Simulator by the State Identification, for the generation of possible mitigation strategies, and the development of an improved user interface which considers the integration of the system in an advanced control room. CAMS is a system developed as a joint research activity at the Halden Reactor Project in close cooperation with member organisations. The project, started in 1993, has now arrived to the second prototype version, which has been presented and demonstrated at several seminars and workshops around the world. (author)

Computerised instruction means teaching by computer using a program that alternates information with self-checking multiple choice questions. This system was used to create a fully computerized lesson on the diagnosis and treatment of breast cancer which was then tested on a small group of madical students attending the Radiology School of the Milan University Institute of Radiological Sciences. At the end of the test, the students were asked to complete a questionnaire which was then analysed. The computer lesson consisted of 66 text messages and 21 self-checking questions. It aroused considerable interest, though the most common reason was curiosity about a novel system. The degree of fatigue caused was modest despite the fact that the computer lesson was at least as demanding as a traditional lesson, if not more so. The level of learning was considered high and optimised by the use of self-checking questions that were considered an essential element. However no student agreed to sit an official examination, even interactively, using the computer

Is primary care ready to embrace e-health? A qualitative study of staff in a London primary care trust

Directory of Open Access Journals (Sweden)

Rishi Mannan

2006-06-01

Conclusions At the time of the study the systems that form part of NHS Connecting for Health, apart from the Quality Management and Analysis System (QMAS, were not implemented across the PCT. All the practices in the study acknowledged the benefits new technology would bring to the workplace, but there were also some common concerns, which suggest that staff working in primary care practices are not ready for e-health. Successful implementation of the NHS Connecting for Health programme rests on identifying, acknowledging and overcoming these concerns. A different approach might be required for those practices that have made very little progress in using email or moving towards an electronic patient record. This study suggests that a mistrust of technology and fears as to the heavy initial workload involved in becoming fully computerised have dissuaded some practices from embracing e-health. If NHS Connecting for Health is to be a success, implementation teams might need to focus initially on practices that have been reluctant to use technology to support both clinical care and the day-to-day work of the practice.

Incomplete patient medical history compromises the quality of care provided to a patient while well-kept, adequate patient medical records are central to the provision of good quality of care. According to research, patients have the right to contribute to decision-making affecting their health. Hence, the researchers investigated their views regarding a paper-based system and an electronic medical record (EMR). An explorative approach was used in conducting a survey within selected general practices in the Nelson Mandela Metropole. The majority of participants thought that the use of a paper-based system had no negative impact on their health. Participants expressed concerns relating to the confidentiality of their medical records with both storage mediums. The majority of participants indicated they prefer their GP to computerise their consultation details. The main objective of the research on which this poster is based was to investigate the storage medium of preference for patients and the reasons for their preference. Overall, 48% of the 85 participants selected EMRs as their preferred storage medium and the reasons for their preference were also uncovered.

Static analysis: from theory to practice; Static analysis of large-scale embedded code, generation of abstract domains

2009-06-01

Software operating critical systems (aircraft, nuclear power plants) should not fail - whereas most computerised systems of daily life (personal computer, ticket vending machines, cell phone) fail from time to time. This is not a simple engineering problem: it is known, since the works of Turing and Cook, that proving that programs work correctly is intrinsically hard. In order to solve this problem, one needs methods that are, at the same time, efficient (moderate costs in time and memory), safe (all possible failures should be found), and precise (few warnings about nonexistent failures). In order to reach a satisfactory compromise between these goals, one can research fields as diverse as formal logic, numerical analysis or 'classical' algorithmics. From 2002 to 2007 I participated in the development of the Astree static analyser. This suggested to me a number of side projects, both theoretical and practical (use of formal proof techniques, analysis of numerical filters...). More recently, I became interested in modular analysis of numerical property and in the applications to program analysis of constraint solving techniques (semi-definite programming, SAT and SAT modulo theory).

Emergency department attendances with chest pain requiring assessment for acute coronary syndrome (ACS) are a major global health issue. Standard assessment includes history, examination, electrocardiogram (ECG) and serial troponin testing. Computerised tomography coronary angiography (CTCA) enables additional anatomical assessment of patients for coronary artery disease (CAD) but has only been studied in very low-risk patients. This trial aims to investigate the effect of early CTCA upon interventions, event rates and health care costs in patients with suspected/confirmed ACS who are at intermediate risk. Participants will be recruited in about 35 tertiary and district general hospitals in the UK. Patients ≥18 years old with symptoms with suspected/confirmed ACS with at least one of the following will be included: (1) ECG abnormalities, e.g. ST-segment depression >0.5 mm; (2) history of ischaemic heart disease; (3) troponin elevation above the 99 th centile of the normal reference range or increase in high-sensitivity troponin meeting European Society of Cardiology criteria for 'rule-in' of myocardial infarction (MI). The early use of ≥64-slice CTCA as part of routine assessment will be compared to standard care. The primary endpoint will be 1-year all-cause death or recurrent type 1 or type 4b MI at 1 year, measured as the time to such event. A number of secondary clinical, process and safety endpoints will be collected and analysed. Cost effectiveness will be estimated in terms of the lifetime incremental cost per quality-adjusted life year gained. We plan to recruit 2424 (2500 with ~3% drop-out) evaluable patients (1212 per arm) to have 90% power to detect a 20% versus 15% difference in 1-year death or recurrent type 1 MI or type 4b MI, two-sided p Acute Coronary Events score, previous CAD and baseline troponin level.

Demand modelling for central heating systems

Energy Technology Data Exchange (ETDEWEB)

Heller, A.

2000-07-01

Most researchers in the field of heat demand estimation have focussed on explaning the load for a given plant based on rather few measurements. This approach is simply the only one adaptable with the very limited data material and limited computer power. This way of dealing with the subject is here called the top-down approach, due to the fact that one tries to explain the load from the overall data. The results of such efforts are discussed in the report, leading to inspiration for own work. Also the significance of the findings to the causes for given heat loads are discussed and summarised. Contrary to the top-down approach applied in literature, a here-called bottom-up approach is applied in this work, describing the causes of a given partial load in detail and combining them to explain the total load for the system. Three partial load 'components' are discussed: 1) Space heating. 2) Hot-Water Consumption. 3) Heat losses in pipe networks. The report is aimed at giving an introduction to these subjects, but at the same time at collecting the previous work done by the author. Space heating is shortly discussed and loads are generated by an advanced simulation model. A hot water consumption model is presented and heat loads, generated by this model, utilised in the overall work. Heat loads due to heat losses in district heating a given a high priority in the current work. Hence a detailed presentation and overview of the subject is given to solar heating experts normally not dealing with district heating. Based on the 'partial' loads generated by the above-mentioned method, an overall load model is built in the computer simulation environment TRNSYS. The final tool is then employed for the generation of time series for heat demand, representing a district heating area. The results are compared to alternative methods for the generation of heat demand profiles. Results form this comparison will be presented. Computerised modelling of systems

A "Social Bitcoin" could sustain a democratic digital world

A multidimensional financial system could provide benefits for individuals, companies, and states. Instead of top-down control, which is destined to eventually fail in a hyperconnected world, a bottom-up creation of value can unleash creative potential and drive innovations. Multiple currency dimensions can represent different externalities and thus enable the design of incentives and feedback mechanisms that foster the ability of complex dynamical systems to self-organize and lead to a more resilient society and sustainable economy. Modern information and communication technologies play a crucial role in this process, as Web 2.0 and online social networks promote cooperation and collaboration on unprecedented scales. Within this contribution, we discuss how one dimension of a multidimensional currency system could represent socio-digital capital (Social Bitcoins) that can be generated in a bottom-up way by individuals who perform search and navigation tasks in a future version of the digital world. The incentive to mine Social Bitcoins could sustain digital diversity, which mitigates the risk of totalitarian control by powerful monopolies of information and can create new business opportunities needed in times where a large fraction of current jobs is estimated to disappear due to computerisation.

Using MIQUEST in General Practice

Full Text Available This paper describes ten months' experience with MIQUEST software used for the collection of data from computerised databases in General Practice. We report on the following: the MIQUEST software in use, the time costs to the practice, the completeness of confidentiality barriers and the accuracy of data collected using MIQUEST compared with similar data collected by the practice system (EMIS. There were no problems encountered with installation of MIQUEST-related software. With experience, MIQUEST was equal to the practice system for speed and ease of use. The confidentiality safeguards were found to be in accordance with the GMSC/RCGP Guidelines - patients could not be directly, or indirectly, identified from the data extracted by external searches. Inaccuracies in the data collected using MIQUEST were identified, but these were largely attributable to problems with the EMIS-written interpreter available on the practice system at the time, or with the coding schemes used by the practice. In an individual practice, MIQUEST represents an alternative data collection method to the practice-based software. For data collection from multiple general practices it should prove an invaluable tool for Health Authorities and research organisations.

This paper describes a rapid and accurate method of point-counting sands and silt-size in unconsolidated open-ocean sediments. As traditional techniques for this operation cannot be employed on the fine-grained material which frequently forms the bulk of deep sea marine sediments, an alternative method has been sought. The method described makes use of equipment known as QUANTEX-RAY comprising a computerised data acquisition and reduction system designed for use in X-ray energy spectrometry and used in conjunction with a scanning electron microscope (SEM). Grains that cannot be identified by their visual morphology in the scanning electron microscope are analysed by X-ray spectrometry. Spectra are acquired in 200 seconds or less and processed by a sequence of software routines under semi-automatic control producing a listing of oxide concentrations as the final result. Each user must customize the control programme and operating conditions to suit his requirements

Aphasia affects the ability to speak, comprehend spoken language, read and write. One third of stroke survivors experience aphasia. Evidence suggests that aphasia can continue to improve after the first few months with intensive speech and language therapy, which is frequently beyond what resources allow. The development of computer software for language practice provides an opportunity for self-managed therapy. This pragmatic randomised controlled trial will investigate the clinical and cost effectiveness of a computerised approach to long-term aphasia therapy post stroke. A total of 285 adults with aphasia at least four months post stroke will be randomly allocated to either usual care, computerised intervention in addition to usual care or attention and activity control in addition to usual care. Those in the intervention group will receive six months of self-managed word finding practice on their home computer with monthly face-to-face support from a volunteer/assistant. Those in the attention control group will receive puzzle activities, supplemented by monthly telephone calls. Study delivery will be coordinated by 20 speech and language therapy departments across the United Kingdom. Outcome measures will be made at baseline, six, nine and 12 months after randomisation by blinded speech and language therapist assessors. Primary outcomes are the change in number of words (of personal relevance) named correctly at six months and improvement in functional conversation. Primary outcomes will be analysed using a Hochberg testing procedure. Significance will be declared if differences in both word retrieval and functional conversation at six months are significant at the 5% level, or if either comparison is significant at 2.5%. A cost utility analysis will be undertaken from the NHS and personal social service perspective. Differences between costs and quality-adjusted life years in the three groups will be described and the incremental cost effectiveness ratio

Some Problems Associated With the Application of Copyright Law Within the Music Industry

OpenAIRE

Miroslav Skoro

2009-01-01

This work examines the historical, philosophical and legal particulars relating to copyright law and intellectual property as an intangible work, as well as, the practical application of those rights with emphasis on the particular effects of computerisation and the emergance of the internet on the business results of the music industry. A question is raised as to whether it is businessly ethical for a legal entity to accrue considerable material gain as the result of illegal usage of copywri...

UK Chemical Nuclear Data Committee progress report

Basic nuclear data requirements for industrial application are monitored by the UK Chemical Nuclear Data Committee (UKCNDC), covering half-lives, decay data, fission yields and the content of computerised data files. While the UKCNDC Request list was reviewed at the end of 1989 to reveal new and continued requirements, funding problems have increased during the year. Difficulties in the UK nuclear power industry are reflected in the decline in experimental studies, although evaluation efforts have been maintained. (author)
