    Development of surgical care in the 21st century is increasingly dependent on demonstrating safety, efficacy and cost effectiveness. Over the past 2 decades, the potential role of simulation in surgery has been explored with encouraging results; this can now be linked to direct improvement in the quality of care provision. Computer-assisted surgical platforms, such as robotic surgery, offer us the versatility to embrace a host of technical and technological developments. Rapid development in nanomedicine will expand the limits of operative performance through improved navigation and surgical precision. Integration of the multiple functions of the future operating room will be essential in optimising resource management. The key to bringing about the necessary paradigm shift in the design and delivery of modern surgical care is to appreciate that we now function in an information age, where the integrity of processes is driven by apt data management.

    Business companies, which in the current times also includes hospitals, must create customer benefits and as a prerequisite for this must sustainably generate profits. Management in the world of business means the formation and directing of a company or parts of a company on a permanent basis, whereby management in this context is not exercising power but function. This concept of management is exemplary developed in this article for the important services sector of the operating room (OR) and individual functions, such as resource control, capacity planning and materials administration are presented in detail. Some OR-specific management challenges are worked out. From this it becomes clear that the economic logic of the most efficient implementation possible is not a contradiction of medical ethics, enabling the most effective treatment possible for patients while safeguarding the highest possible levels of safety and quality. The article aims to build a bridge for medical specialists to the language and world of commerce, emphasizing the profession-based competence and hopefully to arouse interest to go into more detail.

    We examine operating room productivity on the example of hospitals in Germany with independent anesthesiology departments. Linked to anesthesiology group literature, we use the ln(Total Surgical Time/Total Anesthesiologists Salary) as a proxy for operating room productivity. We test the association between operating room productivity and different structural, organizational and management characteristics based on survey data from 87 hospitals. Our empirical analysis links improved operating room productivity to greater operating room capacity, appropriate scheduling behavior and management methods to realign interests. From this analysis, the enforcing jurisdiction and avoiding advance over-scheduling appear to be the implementable tools for improving operating room productivity.

    Metaphor is a means through which a widely accepted meaning of a word is used in a different context to add understanding that would otherwise be difficult to conceive. Through etymological and metaphorical associations, we contend that aspects of "theatre" are still relevant in the modern operating rooms and that the use of dramaturgical metaphors can add another layer of understanding about the social reality in this setting. We begin by exploring the historical roots and derivation of the word theatre as it applied to anatomical dissection and surgery. Briefly, we touch on the work of Erving Goffman and examine how his work has been used by others to explore aspects of operating room nursing. Then, drawing on data from a postmodern ethnographic study that has been used to examine communication in operating room nursing, four dramaturgical metaphors are used to illustrate the argument. They are drama, the script and learning the lines, the show must go on, and changing between back stage and front stage. To conclude, the small amount of previously published literature on this topic is compared and contrasted, and the relevance of using dramaturgical metaphors to understand modern operating rooms is discussed. Being able to distinguish between the inherent drama in operating room work and the dramatic realisation of individuals who work within, can help operating room nurses to think differently about, and perhaps re-evaluate their social situation and how they function within it.

    The last two decades have seen a paradigm shift in the treatment of vascular related diseases from once traditional open surgical repairs to the entire vascular tree being amenable to percutaneous interventions. Neither the classic operating room nor the conventional angiography suite is optimal for both open surgery and endovascular procedures. Important issues for the vascular hybrid operating room include quality of the imaging equipment, radiation burden, ease of use of the equipment, need for specially trained personnel, ergonomics, ability to perform both open and percutaneous procedures, sterile environments, as well as quality and efficiency of patient care. The most important feature of working in a dedicated hybrid vascular suite should be the ability to attain best treatment of vascular patients. Whether the interventional radiologist or the vascular surgeon uses the facilities is of less importance. Establishment of an endovascular operating room suite has the benefit of a sterile environment, and the possibility of performing hybrid procedures and conversions when necessary. Moreover, angiography immediately before treatment gives contemporary anatomical information, and after treatment provides quality control. Consequently, better quality and service can be provided to the individual patient. These changes in the treatment of vascular disease require that a new type of vascular specialist, named 'vascular hybrid surgeon', trained to perform both endovascular and open surgical procedures in this highly complex patient group.

    An increasing number of minor surgical procedures are performed under local anaesthesia in clinical settings outside the operating room, where monitoring and resuscitation equipment--as well as personnel skilled in resuscitation--may not be readily available. Serious adverse effects and even fatalities may result from the use of local anaesthetic agents, arising from a variety of causes such as systemic toxicity, allergy, vasovagal syncope, and reaction to additives present in the local anaesthetic. This article briefly reviews the pharmacology of local anaesthetic agents, and describes various techniques commonly used for local anaesthesia, with special emphasis on safety. Clinical features of toxicity, and its differential diagnosis and management, are also discussed.

    Operating and maintaining a tornado safe room can be critical to the effective continuity of business operations because a firm's most valuable asset is its people. This paper describes aspects of operations and maintenance (O&M) for existing tornado safe rooms as well as a few planning and design aspects that affect the ultimate operation of a safe room for situations where a safe room is planned, but not yet constructed. The information is based on several Federal Emergency Management Agency safe room publications that provide guidance on emergency management and operations, as well as the design and construction of tornado safe rooms.

    ➤ Although there is some evidence that scrubs, masks, and head coverings reduce bacterial counts in the operating room, there is no evidence that these measures reduce the prevalence of surgical site infection.➤ The use of gloves and impervious surgical gowns in the operating room reduces the prevalence of surgical site infection.➤ Operating-room ventilation plays an unclear role in the prevention of surgical site infection.➤ Exposure of fluids and surgical instruments to the operating-room environment can lead to contamination. Room traffic increases levels of bacteria in the operating room, although the role of this contamination in surgical site infection is unclear.

    Human reliability is the probability that a person correctly performs some system required action in a required time period and performs no extraneous action that can degrade the system Human reliability analysis (HRA) is the analysis, prediction and evaluation of work-oriented human performance using some indices as human error likelihood and probability of task accomplishment. Significant progress has been made in the HRA field during the last years, mainly in nuclear area. Some first-generation HRA methods were developed, as THERP (Technique for human error rate prediction). Now, an array of called second-generation methods are emerging as alternatives, for instance ATHEANA (A Technique for human event analysis). The ergonomics approach has as tool the ergonomic work analysis. It focus on the study of operator's activities in physical and mental form, considering at the same time the observed characteristics of operator and the elements of the work environment as they are presented to and perceived by the operators. The aim of this paper is to propose a methodology to analyze the human reliability of the operators of industrial plant control room, using a framework that includes the approach used by ATHEANA, THERP and the work ergonomics analysis.

    In this study, communication research was conducted with multidisciplinary groups of operating-room physicians. Theoretical frameworks from intercultural communication and rhetoric were used to (a) measure latent cultural communication variables and (b) conduct communication training with the physicians. A six-step protocol guided the research with teams of physicians from different surgical specialties: anesthesiologists, general surgeons, and obstetrician-gynecologists (n = 85). Latent cultural communication variables were measured by surveys administered to physicians before and after completion of the protocol. The centerpiece of the 2-hour research protocol was an instructional session that informed the surgical physicians about rhetorical choices that support participatory communication. Post-training results demonstrated scores increased on communication variables that contribute to collaborative communication and teamwork among the physicians. This study expands health communication research through application of combined intercultural and rhetorical frameworks, and establishes new ways communication theory can contribute to medical education.

    Full Text Available Introduction. Long term exposure to trace amounts of anesthetic vapors and gases may produce hematologic and hepatic disorders in human. Since operating room (OR staffs are exposed to these agents, we decided to study their hematopoietic and hepatic systems in comparison with ordinary ward staffs. Methods. Seventy staffs from OR were compared with a matched similar number of ward staffs about their hematologic and hepatic laboratory findings in a historical cohort study. Findings. Mean of leukocyte and platelet counts were significantly lower in OR staffs, but in normal range. Mean of monocyte count was significantly higher in OR staffs. No significant differences were found between two groups for other hepatic and hematologic tests. Fatigue and headache were reported in OR staffs more than others. Conclusion. These findings may warn a risk to OR staffs but, it is not clear and requires further controlled studies.

    Many resources are expended to ensure a sterile operating room environment. Efforts are made to prevent exposure of patients to personnel and to achieve positive room pressure to keep out airborne contaminants. Foot traffic into and out of the operating room during surgery can undermine these efforts. The authors investigated the number and duration of operating room door openings during hip and knee arthroplasty procedures and the effect of the door openings on room pressure. They tested the hypothesis that door openings defeat positive pressure, permitting air flow into the room. Room pressure and door status were monitored electronically during 191 hip and knee arthroplasty procedures. Operating room staff were unaware that data were being collected. The authors evaluated the data with regression analysis to determine whether the number and duration of door openings had an effect on room pressure. Significance was set at Poperating room. Total time with the door open significantly affected the minimum pressure recorded in the room (Poperating room sterility. The causes of excessive operating room traffic must be evaluated to identify ways to reduce this traffic and the associated risks.

    To investigate the workplace culture in the Operating Room (OR) environment and the factors associated with it. In health care, the workplace culture affects the delivery and experience of care. The OR can be a stressful practice environment, where nurses might have occasionally either job stress or job satisfaction based on their competence. A quantitative cross-sectional approach was used. The study consisted of 96 Finnish OR nurses. A Nursing Context Index instrument was used to obtain data by way of an electronic questionnaire. The primary role and working unit of respondents were the main components relating to workplace culture, and especially to job stress. Nurse anaesthetists were found to be slightly more stressed than scrub nurses. In local hospitals, job stress related to workload was perceived less than in university hospitals (P = 0.001). In addition, OR nurses in local hospitals were more satisfied with their profession (P = 0.007), particularly around issues concerning adequate staffing and resources (P = 0.001). It is essential that nurse managers learn to recognise the different expressions of workplace culture. In particular, this study raises a need to recognise the factors that cause job stress to nurse anaesthetists. © 2016 John Wiley & Sons Ltd.

    Implementation of an operating room (OR) pharmacy satellite is described, and its impact on cost-effectiveness and efficiency of drug distribution is analyzed. The OR satellite provided pharmacy coverage for 30-35 patients per day in 10 centralized surgical suites, 2 obstetric suites, and 1 burn-unit suite in a 401-bed teaching hospital. Objectives of the satellite were to consolidate accountability for drug distribution and control, reduce controlled substance loss and waste, reduce inventory costs, and improve recording of patient charges. Stock on the OR supply cart was reduced, controlled substances were dispensed to anesthesiologists from the satellite, and a system of standardized anesthesiology exchange trays was developed. A new billing form served as both the charging document and replacement list. Reduction in the medication cart stock resulted in smaller discrepancies in patient charges. For the five most commonly used controlled substances, accounting discrepancies were reduced. Inventory turnover increased and inventory dollar value and cost per patient were reduced. The percent of nurses who believed that a pharmacist should work in the area increased from 31% before implementation of the satellite to 95% after. The pilot OR pharmacy satellite was a financial success. Efficiency and effectiveness in drug distribution and control were improved, and communication between pharmacists and other medical personnel working in the OR areas was enhanced.

    Since the increase of the number of technological aids in the operating room (OR), equipment-related incidents have come to be a common kind of adverse events. This underlines the importance of adequate equipment management to improve the safety in the OR. A system was developed to monitor the safety status (periodic maintenance and registered malfunctions) of OR devices and to facilitate the notification of malfunctions. The objective was to assess whether the system is suitable for use in an busy OR setting and to analyse its effect on the notification of malfunctions. The system checks automatically the safety status of OR devices through constant communication with the technical facility management system, informs the OR staff real-time and facilitates notification of malfunctions. The system was tested for a pilot period of six months in four ORs of a Dutch teaching hospital and 17 users were interviewed on the usability of the system. The users provided positive feedback on the usability. For 86.6% of total time, the localisation of OR devices was accurate. 62 malfunctions of OR devices were reported, an increase of 12 notifications compared to the previous year. The safety status system was suitable for an OR complex, both from a usability and technical point of view, and an increase of reported malfunctions was observed. The system eases monitoring the safety status of equipment and is a promising tool to improve the safety related to OR devices.

    Operating room nursing is an under-researched area of nursing practice. The stereotypical image of operating room nursing is one of task- and technically-orientated aspects of practice, where nurses work in a medical model and are dominated by constraints from outside their sphere of influence. This paper explores the possibility of understanding operating room nursing in a different way. Using the work of Michel Foucault to analyse the work of operating room nursing, this paper argues the relevance of the framework for a more in-depth analysis of this specialty area of practice. The concepts of power, discipline and subjectivity are used to demonstrate how operating room nursing is constructed as a discipline and how operating room nurses act to govern and construct the specialty. Exemplars are drawn from extensive professional experience, from guidelines of professional operating room nursing associations, as well as published texts. The focus is predominantly on the regulation of space and time to maintain the integrity of the sterile surgical field and issues of management, as well as the use of the ethical concept of the 'surgical conscience'. This form of analysis provides a level and depth of inquiry that has rarely been undertaken in operating room nursing. As such, it has the potential to provide a much needed, different view of operation room nursing that can only help to strengthen its professional foundations and development.

    Full Text Available Background: The first step in cultivating the culture of safety in the operating room is the assessment of safety culture among operating room personnel. Objective: To assess the patient safety culture of operating room personnel at the Department of Surgery, Faculty of Medicine Siriraj Hospital, and compare attitudes among different groups of personnel, and compare them with the international standards. Methods: We conducted a cross-sectional survey of safety attitudes among 396 operating room personnel, using a short form of the Safety Attitudes Questionnaire (SAQ. The SAQ employed 30 items to assess safety culture in six dimensions: teamwork climate, safety climate, stress recognition, perception of hospital management, working conditions, and job satisfaction. The subscore of each dimension was calculated and converted to a scale score with a full score of 100, where higher scores indicated better safety attitudes. Results: The response rate was 66.4%. The overall safety culture score of the operating room personnel was 65.02, higher than an international average (61.80. Operating room personnel at Siriraj Hospital had safety attitudes in teamwork climate, safety climate, and stress recognition lower than the international average, but had safety attitudes in the perception of hospital management, working conditions, and job satisfaction higher than the international average. Conclusion: The safety culture attitudes of operating room personnel at the Department of Surgery, Siriraj Hospital were comparable to international standards. The safety dimensions that Siriraj Hospital operating room should try to improve were teamwork climate, safety climate, and stress recognition.

    In operating rooms great effort is manifested to reduce the bacteria level in order to decrease the risk of infections. The main source of bacteria is the staff and the patient, thus, the resulting bacteria concentration is roughly speaking a combination of the ventilation system and the emission...... from the occupants. This study investigates the influence of two main disturbances in an operating room namely the door opening during the operation and the activity level of the staff. It is found that the frequent door opening in this case does not cause significant transport of air from outside...... the operating room to the wound area of the patient. However, a significant influence of the activity level on the bacteria emission and concentration is found. Counting the number of persons in an operating room to estimate the bacteria source strength is not sufficient, the corresponding activity level must...

    The surgical rooms of 14 private veterinary practices were monitored to determined methoxyflurane (MOF) concentrations during surgical procedure under routine working conditions. The average room volume for these 14 rooms was 29 m3. The average MOF value for all rooms was 2.3 ppm, with a range of 0.7 to 7.4 ppm. Four of the 14 rooms exceeded the maximum recommended concentration of 2 ppm. Six rooms which had 6 or more air changes/hr averaged 1.1 ppm, whereas 8 rooms with less than 6 measurable air changes/hr averaged 3.2 ppm. Operating rooms that had oxygen flows of more than 1,000 cm3/min averaged 4.4 ppm, whereas those with flows of less than 1,000 cm3/min averaged 1.5 ppm. The average time spent during a surgical procedure using MOF, for all 14 facilities, was 2 hours. Nitrous oxide (N/sub 2/O) concentrations were determined in 4 veterinary surgical rooms. The average N/sub 2/O concentration for 3 rooms without waste anesthetic gas scavenging was 138 ppm. Concentration of N/sub 2/O in the waste anesthetic gas-scavenged surgical room was 14 ppm, which was below the maximum recommended concentration of 25 ppm.

    The difficult financial situation in German hospitals requires measures for improvement in process quality. Associated increases in revenues in the high income field "operating room (OR) area" are increasingly the responsibility of OR management but it has not been shown that the introduction of an efficiency-oriented management leads to an increase in process quality and revenues in the operating theatre. Therefore the performance in the operating theatre of the University Medical Center Göttingen was analyzed for working days in the core operating time from 7.45 a.m. to 3.30 p.m. from 2009 to 2014. The achievement of process target times for the morning surgery start time and the turnover times of anesthesia and OR-nurses were calculated as indicators of process quality. The number of operations and cumulative incision-suture time were also analyzed as aggregated performance indicators. In order to assess the development of revenues in the operating theatre, the revenues from diagnosis-related groups (DRG) in all inpatient and occupational accident cases, adjusted for the regional basic case value from 2009, were calculated for each year. The development of revenues was also analyzed after deduction of revenues resulting from altered economic case weighting. It could be shown that the achievement of process target values for the morning surgery start time could be improved by 40 %, the turnover times for anesthesia reduced by 50 % and for the OR-nurses by 36 %. Together with the introduction of central planning for reallocation, an increase in operation numbers of 21 % and cumulative incision-suture times of 12% could be realized. Due to these additional operations the DRG revenues in 2014 could be increased to 132 % compared to 2009 or 127 % if the revenues caused by economic case weighting were excluded. The personnel complement in anesthesia (-1.7 %) and OR-nurses (+2.6 %) as well as anesthetists (+6.7 %) increased less compared to the

    The Joint Commission on Accreditation of Healthcare Organizations is proposing that hospitals measure culture beginning in 2007. However, a reliable and widely used measurement tool for the operating room (OR) setting does not currently exist. OR personnel in 60 US hospitals were surveyed using the Safety Attitudes Questionnaire. The teamwork climate domain of the survey uses six items about difficulty speaking up, conflict resolution, physician-nurse collaboration, feeling supported by others, asking questions, and heeding nurse input. To justify grouping individual-level responses to a single score at each hospital OR level, the authors used a multilevel confirmatory factor analysis, intraclass correlations, within-group interrater reliability, and Cronbach's alpha. To detect differences at the hospital OR level and by caregiver type, the authors used multivariate analysis of variance (items) and analysis of variance (scale). The response rate was 77.1%. There was robust evidence for grouping individual-level respondents to the hospital OR level using the diverse set of statistical tests, e.g., Comparative Fit Index = 0.99, root mean squared error of approximation = 0.05, and acceptable intraclasss correlations, within-group interrater reliability values, and Cronbach's alpha = 0.79. Teamwork climate differed significantly by hospital (F59, 1,911 = 4.06, P teamwork climate is possible using this psychometrically sound teamwork climate scale. This tool and initial benchmarks allow others to compare their teamwork climate to national means, in an effort to focus more on what excellent surgical teams do well.

    The Canadian Nurses Association (CNA) values learning from nursing history to provide a contextual perspective in understanding how past events have shaped current nursing practice. Until the publication of operating room nursing journals, Canada's national nursing journal, The Canadian Nurse, served as an educational and professional resource for those nurses working in the operating room and for nurses whose work was related to, or connected with, the operating room. A historical review of early issues of The Canadian Nurse (first published in 1905) reveals a substantial amount of content related to operating room nursing in the twenty year period, beginning in the 1940s, that predated the existence of OR specialty journals. The content was, for the time, both detailed and informative. It was through this journal that operating room nurses, indeed all Canadian nurses, learned about new advances, employment opportunities, educational programs, professional associations, and the achievements of those in the profession. Operating Room Nursing, as an isolated and quickly emerging specialty, was introduced to other nurses via items in The Canadian Nurse journal.

    Full Text Available The system is air conditioning system in operating room. The main objective of the system was implemented to provide air balance and temperature necessary conditions and to control airflow system for ventilation units in operating room. The operation room can be controlled with fuzzy expert system and describes the desired outputs. Input parameters such as temperature, humidity, oxygen and particle are used and output parameters are chosen as air conditioning motor speed and exhaust motor speed. Input parameters of the system are taken into account optimal conditions based on oxygen as medium and other parameters are chosen minimum condition for operating room. The airflow control system is determined the two components: the airflow block and the thermal block for ventilation units in operating room. The mathematical modeling of each such system based on a computational procedure and to combine them together in an efficient manner. Whether it supports to the most suitable control for the system prototype was determined by simulating the operation with varying the number of personnel and duration of time. Finally, according to the combination of temperature and airflow regulations with PI controller, the results of simulation of the entire ventilation unit control system is obtained.

Rresults: As to quality of life, the environment domain obtained the highest score, while the psychological domain obtained the lowest. When asked if their professional activity in the operating room influenced their quality of life, most responded affirmatively. Regarding the justifications offered by the nurses for the influence of their professional activity on their quality of life, 50% mentioned environment-related stress, responsibilities, duties, risk situations, relationships with the multiprofessional team, and the type of work carried out in the operating room. Cconclusions: The psychological domain obtained the lowest score in the nurse quality of life evaluation, pointing out the need to facilitate and/or encourage nurses to seek psychological support. As to the influence of their professional activity on their quality of life, the nurses mentioned stress related to their work environment and professional activities in the operating room. This highlights the importance of managers in this area, paying greater attention to the individual and collective needs of their employees.

    Preventing airborne infections during a surgery has been always an important issue to deliver effective and high quality medical care to the patient. One of the important sources of infection is particles that are distributed through airborne routes. Factors influencing infection rates caused by airborne particles, among others, are efficient ventilation and the arrangement of surgical facilities inside the operating room. The paper studies the ventilation airflow pattern in an operating room in a hospital located in Tehran, Iran, and seeks to find the efficient configurations with respect to the ventilation system and layout of facilities. This study uses computational fluid dynamics (CFD) and investigates the effects of different inflow velocities for inlets, two pressurization scenarios (equal and excess pressure) and two arrangements of surgical facilities in room while the door is completely open. The results show that system does not perform adequately when the door is open in the operating room under the current conditions, and excess pressure adjustments should be employed to achieve efficient results. The findings of this research can be discussed in the context of design and controlling of the ventilation facilities of operating rooms.

    New technologies and innovations are common in the delivery of modern health care. Google Glass is one such device gaining increased attention in medical specialties. The authors surveyed residents and attending physicians in the Department of Plastic Surgery, MedStar Georgetown University Hospital, on their experience using Google Glass in the operating room. Ease of use, quality of images, gaze disruption, and distraction during surgery were measured. Overall, subjects found the device to be comfortable and satisfying to wear and use during surgery to capture images of good quality. Despite some identified weaknesses, Google Glass is a unique technology with a promising plastic surgical application in the operating room.

    A comprehensive surveillance and control system integrating all devices and functions is a precondition for realization of the operating room of the future. Multiple proprietary integrated operation room systems are currently available with a central user interface; however, they only cover a relatively small part of all functionalities. Internationally, there are at least three different initiatives to promote a comprehensive systems integration and networking in the operating room: the Japanese smart cyber operating theater (SCOT), the American medical device plug-and-play interoperability program (MDPnP) and the German secure and dynamic networking in operating room and hospital (OR.NET) project supported by the Federal Ministry of Education and Research. Within the framework of the internationally advanced OR.NET project, prototype solution approaches were realized, which make short-term and mid-term comprehensive data retrieval systems probable. An active and even autonomous control of the medical devices by the surveillance and control system (closed loop) is expected only in the long run due to strict regulatory barriers.

    Title. Silence, power and communication in the operating room Aim This paper is a report of a study conducted to explore whether a 1- to 3-minute preoperative interprofessional team briefing with a structured checklist was an effective way to support communication in the operating room. Background Previous research suggests that nurses often feel constrained in their ability to communicate with physicians. Previous research on silence and power suggests that silence is not only a reflection of powerlessness or passivity, and that silence and speech are not opposites, but closely interrelated. Methods We conducted a retrospective study of silences observed in communication between nurses and surgeons in a multi-site observational study of interprofessional communication in the operating room. Over 700 surgical procedures were observed from 2005–2007. Instances of communication characterized by unresolved or unarticulated issues were identified in field notes and analysed from a critical ethnography perspective. Findings We identified three forms of recurring ‘silences’: absence of communication; not responding to queries or requests; and speaking quietly. These silences may be defensive or strategic, and they may be influenced by larger institutional and structural power dynamics as well as by the immediate situational context. Conclusions There is no single answer to the question of why ‘nobody said anything’. Exploring silences in relation to power suggests that there are multiple and complex ways that constrained communication is produced in the operating room, which are essential to understand in order to improve interprofessional communication and collaboration.

    Delays in the operating room have a negative effect on its efficiency and the working environment. In this prospective study, we analyzed data on perioperative system delays. One neurosurgeon prospectively recorded all errors, including perioperative delays, for consecutive patients undergoing elective procedures from May 2000 to February 2009. We analyzed the prevalence, causes and impact of perioperative system delays that occurred in one neurosurgeon's practice. A total of 1531 elective surgical cases were performed during the study period. Delays were the most common type of error (33.6%), and more than half (51.4%) of all cases had at least 1 delay. The most common cause of delay was equipment failure. The first cases of the day and cranial cases had more delays than subsequent cases and spinal cases, respectively. A delay in starting the first case was associated with subsequent delays. Delays frequently occur in the operating room and have a major effect on patient flow and resource utilization. Thorough documentation of perioperative delays provides a basis for the development of solutions for improving operating room efficiency and illustrates the principles underlying the causes of operating room delays across surgical disciplines.

    There is a direct relationship between the quality of the environment of a workplace and the productivity and efficiency of the work accomplished. Components such as temperature, humidity, ventilation, drafts, lighting, and noise each contribute to the quality of the overall environment and the sense of well-being of those who work there.The modern operating room is a unique workplace with specific, and frequently conflicting, environmental requirements for each of the inhabitants. Even minor disturbances in the internal environment of the operating room can have serious ramifications on the comfort, effectiveness, and safety of each of the inhabitants. A cool, well-ventilated, and dry climate is optimal for many members of the surgical team. Any significant deviation from these objectives raises the risk of decreased efficiency and productivity and adverse surgical outcomes. A warmer, more humid, and quieter environment is necessary for the patient. If these requirements are not met, the risk of surgical morbidity and mortality is increased. An important task for the surgical team is to find the correct balance between these 2 opposed requirements. Several of the components of the operating room environment, especially room temperature and airflow patterns, are easily manipulated by the members of the surgical team. In the following discussion, we will examine these elements to better understand the clinical ramifications of adjustments and accommodations that are frequently made to meet the requirements of both the surgical staff and the patient.

  1. Feasibility of touch-less control of operating room lights.

    2013-03-01

    Today's highly technical operating rooms lead to fairly complex surgical workflows where the surgeon has to interact with a number of devices, including the operating room light. Hence, ideally, the surgeon could direct the light without major disruption of his work. We studied whether a gesture tracking-based control of an automated operating room light is feasible. So far, there has been little research on control approaches for operating lights. We have implemented an exemplary setup to mimic an automated light controlled by a gesture tracking system. The setup includes a articulated arm to position the light source and an off-the-shelf RGBD camera to detect the user interaction. We assessed the tracking performance using a robot-mounted hand phantom and ran a number of tests with 18 volunteers to evaluate the potential of touch-less light control. All test persons were comfortable with using the gesture-based system and quickly learned how to move a light spot on flat surface. The hand tracking error is direction-dependent and in the range of several centimeters, with a standard deviation of less than 1 mm and up to 3.5 mm orthogonal and parallel to the finger orientation, respectively. However, the subjects had no problems following even more complex paths with a width of less than 10 cm. The average speed was 0.15 m/s, and even initially slow subjects improved over time. Gestures to initiate control can be performed in approximately 2 s. Two-thirds of the subjects considered gesture control to be simple, and a majority considered it to be rather efficient. Implementation of an automated operating room light and touch-less control using an RGBD camera for gesture tracking is feasible. The remaining tracking error does not affect smooth control, and the use of the system is intuitive even for inexperienced users.

    Although adults may be able to tolerate procedures without sedation, developmental and cognitive issues often mandate the use of sedation in infants and children. There has been a shift in the philosophy regarding sedation with an increasing recognition of the negative psychological and physiological aspects of inadequate sedation. The expansion of our technology continues to result in an increasing number of techniques, which require sedation outside of the operating room environment. These factors have contributed to an ever growing number of pediatric patients presenting themselves for procedural sedation. This chapter will discuss issues regarding the provision of anesthesia outside of the operating room for pediatric patients including current guidelines for patient assessment prior to procedural, monitoring during sedation, and a discussion of some of the more commonly utilized sedative and analgesic agents within the pediatric population.

    In 2010, our department instituted a nonclinical, administrative rotation in operating room management for anesthesiology residents. Subsequently, we mandated the rotation for all senior anesthesiology residents in 2013. In 2014, under the auspices of the American Society of Anesthesiologists, we developed a web-based module covering the basics of finance, accounting, and operating room management. A multiple-choice test was given to residents at the beginning and end of the rotation, and we compared the mean scores between residents who took the traditional course and residents who took the web-based module. We found no significant difference between the groups of residents, suggesting that the web-based module is as effective as traditional didactics.

    In order to maintain air cleanliness in the operating room (OR) permanently, air exchange rate in the OR should be more than 15 times x hr(-1), the laminar air flow should be kept, and the numbers of the persons in the OR and the numbers of opening and closing OR door should be limited. High efficiency particulate air (HEPA) filter is effective in collection and removal of airborne microbes, and is used in the biological clean room. We need to design, equip, and manage the OR environment according to Guideline for Design and Operation of Hospital HVAC Systems HEAS-02-2004 established by Healthcare Engineering Association of Japan and Guideline for Prevention of Surgical Site Infection (SSI) established by the Center for Disease Control and Prevention (CDC) in the USA.

    Online image guidance in the operating room using ultrasound imaging led to the resurgence of prostate brachytherapy in the 1980s. Here we describe the evolution of integrating MRI technology in the brachytherapy suite or operating room. Given the complexity, cost, and inherent safety issues associated with MRI system integration, first steps focused on the computational integration of images rather than systems. This approach has broad appeal given minimal infrastructure costs and efficiencies comparable with standard care workflows. However, many concerns remain regarding accuracy of registration through the course of a brachytherapy procedure. In selected academic institutions, MRI systems have been integrated in or near the brachytherapy suite in varied configurations to improve the precision and quality of treatments. Navigation toolsets specifically adapted to prostate brachytherapy are in development and are reviewed. Copyright © 2017 American Brachytherapy Society. Published by Elsevier Inc.

    Surgical expertise demands technical and nontechnical skills. Traditionally, surgical trainees acquired these skills in the operating room; however, operative time for residents has decreased with duty hour restrictions. As in other professions, video analysis may help maximize the learning experience. To develop and evaluate a postoperative video-based coaching intervention for residents. In this mixed methods analysis, 10 senior (postgraduate year 4 and 5) residents were videorecorded operating with an attending surgeon at an academic tertiary care hospital. Each video formed the basis of a 1-hour one-on-one coaching session conducted by the operative attending; although a coaching framework was provided, participants determined the specific content collaboratively. Teaching points were identified in the operating room and the video-based coaching sessions; iterative inductive coding, followed by thematic analysis, was performed. Teaching points made in the operating room were compared with those in the video-based coaching sessions with respect to initiator, content, and teaching technique, adjusting for time. Among 10 cases, surgeons made more teaching points per unit time (63.0 vs 102.7 per hour) while coaching. Teaching in the video-based coaching sessions was more resident centered; attendings were more inquisitive about residents' learning needs (3.30 vs 0.28, P = .04), and residents took more initiative to direct their education (27% [198 of 729 teaching points] vs 17% [331 of 1977 teaching points], P Video-based coaching is a novel and feasible modality for supplementing intraoperative learning. Objective evaluation demonstrates that video-based coaching may be particularly useful for teaching higher-level concepts, such as decision making, and for individualizing instruction and feedback to each resident.

    Full Text Available Background: Healthcare expenditure is a serious concern, with escalating costs failing to meet the expectations of quality care. The treatment capacities are limited in a hospital setting and the operating rooms (ORs. Their optimal utilization is vital in efficient hospital management. Starting late means considerable wait time for staff, patients and waste of resources. We planned an audit to assess different perspectives of the residents in surgical specialities and anesthesia and OR staff nurses so as to know the causative factors of operative delay. This can help develop a practical model to decrease start time delays in operating room (ORs. Aims: An audit to assess different perspectives of the Operating room (OR staff with respect to the varied causative factors of operative delay in the OR. To aid in the development of a practical model to decrease start time delays in ORs and facilitate on-time starts at Jai Prakash Narayan Apex Trauma centre (JPNATC, All India Institute of Medical Sciences (AIIMS, New Delhi. Methods: We prepared a questionnaire seeking the five main reasons of delay as per their perspective. Results: The available data was analysed. Analysis of the data demonstrated the common causative factors in start time operative delays as: a lack of proper planning, deficiencies in team work, communication gap and limited availability of trained supporting staff. Conclusions: The preparation of the equipment and required material for the OR cases must be done well in advance. Utilization of newer technology enables timely booking and scheduling of cases. Improved inter-departmental coordination and compliance with preanesthetic instructions needs to be ensured. It is essential that the anesthesiologists perform their work promptly, well in time . and supervise the proceedings as the OR manager. This audit is a step forward in defining the need of effective OR planning for continuous quality improvement.

    2014-05-15

    With the using of a computer-based control room in an APR1400 (Advanced Pressurized Reactor-1400), the operators' behaviors in the main control room had changed. However, though the working environment of operators has been changed a great deal, digitalized interfaces can also change the cognitive tasks or activities of operators. First, a shift supervisor (SS) can confirm/check the conduction of the procedures and the execution of actions of board operators (BOs) while confirming directly the operation variables without relying on the BOs. Second, all operators added to their work the use of a new CBP and Soft Controls, increasing their procedural workload. New operational control strategies of CBPs are necessary for load balancing of operator's task load in APR1400. In this paper, we compared the workloads of operators in an APR1400 who work with two different usages of the CBP. They are SS oriented usage and SS-BO collaborative usage. In this research, we evaluated the workloads of operators in an advanced main control room by the COCOA method. Two types of CBP usages were defined and the effects of these usages on the workloads were investigated. The obtained results showed that the workloads between operators in a control room can be balanced according to the CBP usages by assigning control authority to the operators.

    In cooperation with the Max-Delbrück-Centrum/Robert-Rössle-Klinik (MDC/RRK) in Berlin, the Fraunhofer Institute for Computer Graphics is currently designing and developing a scenario for the operating room of the future. The goal of this project is to integrate new analysis, visualization and interaction tools in order to optimize and refine tumor diagnostics and therapy in combination with laser technology and remote stereoscopic video transfer. Hence, a human 3-D reference model is reconstructed using CT, MR, and anatomical cryosection images from the National Library of Medicine's Visible Human Project. Applying segmentation algorithms and surface-polygonization methods a 3-D representation is obtained. In addition, a "fly-through" the virtual patient is realized using 3-D input devices (data glove, tracking system, 6-DOF mouse). In this way, the surgeon can experience really new perspectives of the human anatomy. Moreover, using a virtual cutting plane any cut of the CT volume can be interactively placed and visualized in realtime. In conclusion, this project delivers visions for the application of effective visualization and VR systems. Commonly known as Virtual Prototyping and applied by the automotive industry long ago, this project shows, that the use of VR techniques can also prototype an operating room. After evaluating design and functionality of the virtual operating room, MDC plans to build real ORs in the near future. The use of VR techniques provides a more natural interface for the surgeon in the OR (e.g., controlling interactions by voice input). Besides preoperative planning future work will focus on supporting the surgeon in performing surgical interventions. An optimal synthesis of real and synthetic data, and the inclusion of visual, aural, and tactile senses in virtual environments can meet these requirements. This Augmented Reality could represent the environment for the surgeons of tomorrow.

    To measure the safety culture in the robotics surgery operating room before and after implementation of the Robotic Operating Room Computerized Checklist (RORCC). Prospective study. Gynecology surgical staff (n = 32). An urban community hospital. The Safety Attitudes Questionnaire domains examined were teamwork, safety, job satisfaction, stress recognition, perceptions of management, and working conditions. Questions and domains were described using percent agreement and the Cronbach alpha. Paired t-tests were used to describe differences before and after implementation of the checklist. Mean (SD) staff age was 46.7 (9.5) years, and most were women (78%) and worked full-time (97%). Twenty respondents (83% of nurses, 80% of surgeons, 66% of surgical technicians, and 33% of certified registered nurse anesthetists) completed the Safety Attitudes Questionnaire; 6 were excluded because of non-matching identifiers. Before RORCC implementation, the highest quality of communication and collaboration was reported by surgeons and surgical technicians (100%). Certified registered nurse anesthetists reported only adequate levels of communication and collaboration with other positions. Most staff reported positive responses for teamwork (48%; α = 0.81), safety (47%; α = 0.75), working conditions (37%; α = 0.55), stress recognition (26%; α = 0.71), and perceptions of management (32%; α = 0.52). No differences were observed after RORCC implementation. Quality of communication and collaboration in the gynecology robotics operating room is high between most positions; however, safety attitude responses are low overall. No differences after RORCC implementation and low response rates may highlight lack of staff support. Copyright © 2014. Published by Elsevier Inc.

    Conclusions: Diagnostic hysteroscopy is currently considered a valuable investigational tool for endometrial abnormalities and abnormal uterine bleeding. Most of these procedures can be performed in a procedure room setting without I.V. sedation or pre-operative narcotics. In our experience, a utero-sacral block using lidocaine is quite effective in controlling discomfort while passing various instruments through the internal cervical os. These techniques result in good visualization of the endometrial cavity, adequate and appropriate endometrial sampling with tolerable discomfort. The patients spend less time in the hospital, experience a much faster recovery and have less pre-operative restrictions. [Int J Reprod Contracept Obstet Gynecol 2016; 5(12.000: 4164-4173

    Fire in the operating room (OR) is a very distressful and shocking occurrence with potential dramatic consequences. Despite safety rules and rigorous recommendations, such unintentional events do occur every so often. Notably, the vast majority of cases have been reported in the adult population, with very few pediatric cases described to date. Herein, we report on a 16-month-old boy undergoing reconstructive surgery for penoscrotal hypospadias, who experienced an OR fire most likely related to the use of alcohol-based solution ignited by monopolar electrocautery.

    Pulido, Ricardo W; Kester, Benjamin; Schwarzkopf, Ran

    How changes in the surgical team's culture can potentially reduce operating room (OR) traffic. Excessive OR traffic during surgical procedures can present a risk to the patient's safety and recovery. Data suggest that limiting the number of OR personnel during the intraoperative period can reduce excessive OR traffic. However, it is unclear whether the surgeon's verbal intervention can also successfully reduce intraoperative OR traffic. This study compares traffic rates in hip and knee arthroplasty cases against traffic rates during nonarthroplasty cases to examine the effects of verbal interventions implemented by the surgeon to reduce intraoperative traffic. The study consisted of 16 orthopedic surgeons in a noninterventional group and 1 orthopedic surgeon in the interventional group. The surgeon in the interventional group implemented verbal protocols to OR staff to limit excessive intraoperative traffic. Operating room traffic was monitored for 3 consecutive months (January-March 2015) with the use of infrared automated door counters that tracked door openings when someone entered or left the OR. A total of 50 hip and knee arthroplasties cases and 157 nonarthroplasty cases were tracked during the study period. A total of 134 hours and 4482 movements were collected for the hip and knee arthroplasty cases. A total of 498 hours and 22 902 movements were collected for the nonarthroplasty cases. Comparing the 2 groups, the interventional group averaged 33 movements per hour while the noninterventional group averaged 46 movements per hour (P traffic can be reduced through simple verbal protocols established by the surgical team.

    There is an increasing and more complex demand for sedation for procedures out of the operating room. For different reasons, nowadays the administration of sedation varies considerably. We believe that a patient safety approach rather an approach out of corporate or economic interests is desirable. We created a working group of experts within the Spanish Anaesthesia and Reanimation Incident Reporting System (SENSAR) to prepare a series of recommendations through a non-systematic review. These recommendations were validated by an expert panel of 31 anaesthesiologists through two rounds of an adaptation of the Delphi Method where more than 70% agreement was required. The resulting recommendations include previous evaluation, material and staffing needs for sedation for procedures, post-sedation recommendations and activity and quality control advice. We present patient centred recommendations for the safe use of sedation for out of the operating room procedures from the point of view of the professionals with the most experience in its administration. We believe that these can be used as a guide to reduce variability and increase patient safety in the organisation of healthcare. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U.

    The steps involved in justifying and implementing an operating room (OR) pharmacy satellite are described. A hospital administrator's viewpoint on the project is included. Objectives of the satellite were to reduce inventory costs, improve control of distribution, reduce loss of revenue and improve patient charging, improve IV compounding and labeling, and significantly improve narcotic control and accountability. The satellite provides comprehensive services 12 hours a day, five days a week. Effective after-hours procedures have been developed to provide efficient drug distribution when the pharmacy is closed. Achieved benefits of the satellite include decreased drug inventory, improved patient charging, accurate labeling, improved IV compounding, and improved pharmacy/surgery relations. The OR pharmacy satellite is a successful cost-effective operation.

    Surgical operating rooms are cost-intensive parts of health service production. Managing operating units efficiently is essential when hospitals and healthcare systems aim to maximize health outcomes with limited resources. Previous research about operating room management has focused on studying the effect of management practices and decisions on efficiency by utilizing mainly modeling approach or before-after analysis in single hospital case. The purpose of this research is to analyze the synergic effect of strategic decisions and operative management practices on operating room productivity and to use a multiple case study method enabling statistical hypothesis testing with empirical data. 11 hypotheses that propose connections between the use of strategic and operative practices and productivity were tested in a multi-hospital study that included 26 units. The results indicate that operative practices, such as personnel management, case scheduling and performance measurement, affect productivity more remarkably than do strategic decisions that relate to, e.g., units' size, scope or academic status. Units with different strategic positions should apply different operative practices: Focused hospital units benefit most from sophisticated case scheduling and parallel processing whereas central and ambulatory units should apply flexible working hours, incentives and multi-skilled personnel. Operating units should be more active in applying management practices which are adequate for their strategic orientation.

    Full Text Available Background: Appropriate usage of operating room (OR time can improve efficiency of utilization of resources and help to decrease surgical waiting lists. Aims: This study was conducted to evaluate the pattern of usage of OR time in a tertiary referral cancer hospital. Setting and Design: This was a prospective audit carried out over 2 months in 11 major ORs in a cancer hospital. Materials and Methods: OR anesthesiologists filled a standard form for all patients undergoing elective surgery and documented the following times: entry into OR, start of anesthesia, handover to surgeon, incision, start of reversal, end of anesthesia, and shifting out of patient. Statistical Analysis: Median time utilized for various OR processes was calculated. Results: An average of two surgeries were performed per OR session (828 surgeries in 407 OR sessions. Anesthesia and surgery-related processes contributed to 17% and 79%, respectively, of total OR time, with turnover time between cases accounting for the remaining 4%. Fifteen percent (60 out of 407 OR sessions started more than 10 min later than the planned start time, and 17% (70 of 407 of OR sessions ended more than 2 h after the scheduled finish time. An anesthesia procedure room was utilized in only 15% of cases where it could potentially have been used. Conclusion: This audit identified patterns of OR usage in a cancer hospital and helped to detect areas of inefficient utilization. Anesthesia-related processes contributed to 17% of the total OR time.

    Operating room (OR) turnover time (TT) has a broad and significant impact on hospital administrators, providers, staff and patients. Our objective was to identify current problems in TT management and implement a consistent, reproducible process to reduce average TT and process variability. Initial observations of TT were made to document the existing process at a 511 bed, 24 OR, academic medical center. Three control groups, including one consisting of Orthopedic and Vascular Surgery, were used to limit potential confounders such as case acuity/duration and equipment needs. A redesigned process based on observed issues, focusing on a horizontally structured, systems-based approach has three major interventions: developing consistent criteria for OR readiness, utilizing parallel processing for patient and room readiness, and enhancing perioperative communication. Process redesign was implemented in Orthopedics and Vascular Surgery. Comparisons of mean and standard deviation of TT were made using an independent 2-tailed t-test. Using all surgical specialties as controls (n = 237), mean TT (hh:mm:ss) was reduced by 0:20:48 min (95 % CI, 0:10:46-0:30:50), from 0:44:23 to 0:23:25, a 46.9 % reduction. Standard deviation of TT was reduced by 0:10:32 min, from 0:16:24 to 0:05:52 and frequency of TT≥30 min was reduced from 72.5to 11.7 %. P systems-based focus should drive OR TT design.

    Neurosurgical patients may be unaware of components of their intra-operative care. The relationship between patient gender and comfort level in the neurosurgical operating room (OR) has not been previously studied. Our objective was to gain insight into patients' perspective of the OR environment, including staffing and observers, the role of medical students, catheterization, exposure, and verbiage, using a qualitative needs assessment. Face-to-face semi-structured interviews were conducted with 20 patients (14 female, six male) who had a neurosurgical operation under general anesthetic within the previous two years. The majority underwent craniotomy for benign tumours. Interviews were transcribed and subjected to modified thematic analysis. Nine themes emerged: 1) perception of the intra-operative environment varies between men and women; 2) lacking awareness about observers is anxiety-provoking for women; 3) being unaware of the hands-on involvement of students is a concern for all patients; 4) disclosure of implantation of foreign and permanent materials into patients is important; 5) catheterization is anxiety provoking for women; 6) pre-operative menstruation screening may minimize embarrassment for women; 7) patients perceive extraneous conversation as a distraction for surgeons; 8) patients trust their surgeon; 9) a relationship exists between interviewer gender and patient comfort in the interview. Although most male and female patients are unaware of OR activities, they are generally not fearful since they trust their surgeon. Women appear to have greater information needs. Patients' information needs must be met without provoking anxiety and yet preserving their personal sense of modesty in the intra-operative environment.

    Full Text Available A risk management program based on AS–NZS4360 risk management standards was developed and implemented in the operating room of Peking University Third Hospital. To accomplish this task, we developed a risk quantification matrix and a risk register form to identify potential risks in the operating room, and then implemented operating room policies designed to reduce or eliminate those risks. We also established a consultation mechanism and risk monitoring system designed to minimize risks to operation room nurses. Finally, we continuously seek to improve our operating room risk management capabilities, so we can continue to improve the quality of service provided and guarantee the safety of surgical patients.

    Anesthesia services can account for a significant portion of a healthcare organization's costs. Deaconess Hospital of Evansville, Indiana, used a collaborative, multidisciplinary effort to implement process improvements that yielded significant cost savings while improving patient care. Shifting responsibility for drug distribution from the operating room (OR) nurses to a pharmacist, the hospital established a satellite pharmacy service for the OR. As a result, the hospital was able to improve control of drug distribution and record-keeping, reduce turnaround time for medication preparation, lower its medication charge error rate, and increase the percentage of surgeries that start on time. The success of the OR satellite pharmacy led the hospital to expand satellite pharmacy services to labor and delivery, the cardiac cath laboratory, and the intensive care units.

    Noise is a health hazard and a source of stress, and it impairs concentration and communication. Since 1960, hospital noise levels have risen around the world. Nowhere in the healthcare setting is noise more prevalent than in the operating room (OR). The genetic makeup of humans does not evolve at the rate of technology. Noise exposure, sensory overload, and the capacity to adapt without physical and psychological consequences are absent from the human condition. The World Health Organization has recognized environmental noise as harmful pollution that causesadverse effects on health. Although noise in the OR is unavoidable, music is a choice. The purpose of this literature review is to provide further insight into the ramifications of the presence of music in the OR, evaluate its appropriateness in relation to care and safety for the patient and staff, and provide information for future research.

    Health care resources are costly and should be used judiciously and efficiently. Predicting the duration of surgical procedures is key to optimizing operating room resources. Our objective was to identify factors influencing operative time, particularly surgical team turnover. We performed a single-institution, retrospective review of lobectomy operations. Univariate and multivariate analyses were performed to evaluate the impact of different factors on surgical time (skin-to-skin) and total procedure time. Staff turnover within the nursing component of the surgical team was defined as the number of instances any nurse had to leave the operating room over the total number of nurses involved in the operation. A total of 235 lobectomies were performed by 5 surgeons, most commonly for lung cancer (95%). On multivariate analysis, percent forced expiratory volume in 1 second, surgical approach, and lesion size had a significant effect on surgical time. Nursing turnover was associated with a significant increase in surgical time (53.7 minutes; 95% confidence interval, 6.4-101; P = .026) and total procedure time (83.2 minutes; 95% confidence interval, 30.1-136.2; P = .002). Active management of surgical team turnover may be an opportunity to improve operating room efficiency when the surgical team is engaged in a major pulmonary resection.

    Indoor environmental quality (IEQ) in hospital operating rooms (ORs) constitutes a major challenge for the proper design and operation of an energy efficient hospital. A subjective assessment of the indoor environment along with a short monitoring campaign was performed during the audits of 18 ORs at nine major Hellenic hospitals. A total of 557 medical personnel participated in an occupational survey, providing data for a subjective assessment of IEQ in the audited ORs. The OR personnel reported work related health symptoms and an assessment of indoor conditions (thermal, visual and acoustical comfort, and air quality). Overall, personnel reported an average of 2.24 work-related symptoms each, and 67.2% of respondents reported at least one. Women suffer more health symptoms than men. Special dispositions, such as smoking and allergies, increase the number of reported symptoms for male and female personnel. Personnel that perceive satisfactory indoor comfort conditions (temperature, humidity, ventilation, light, and noise) average 1.18 symptoms per person, while for satisfactory indoor air quality the average complaints are 0.99. The perception of satisfactory IEQ (satisfactory comfort conditions and air quality) reduces the average number of health complaints to 0.64 symptoms per person and improves working conditions, even in a demanding OR environment.

    A dedicated fluoroscopic-compatible operating room (OR) for endourologic procedures, such as percutaneous nephrolithotomy and ureteroscopy, is structurally and functionally different from the general OR. Publications with practical details are scarce, imposing a challenge in construction of such an OR. We outline a practical approach for the design and construction of a modern flourocompatible endourology OR. There were no publications related to a dedicated endourology OR in Medline. A search was then performed for English language articles on OR designing, fluoroscopy in the OR, data archiving, and data relay. We also surveyed the existing endourology OR in different hospitals and analyzed the available technology for audiovisual capture and relay in surgery. This article was then prepared, covering the relevant areas on designing a dedicated flourocompatible endourology OR. Close cooperation and interaction between an architect and expert construction manager for designing, development, and construction of an OR are necessary. Strategic equipment placement with booms is essential to increase the efficiency and safety within the surgical space. Distinct features of an endourology OR are thickness of the walls for radiation protection, wide OR gate, central floor water exit drain, flourocompatible rotatable OR table, C-arm unit, minimum three hanging thin-film transistor (TFT) screen monitors, and endoscopic equipment supported on a boom. The anesthetic boom should be retractable and movable from one end of the OR table to other. The OR should have an electronic workstation strategically located at one corner for data capture, archiving, and telementoring. Data relay of the OR procedure is facilitated by a control room located in the vicinity of the OR. Designing the layout of the OR is extremely important, necessitating thoughtful planning to provide hassle-free movement, comfort to the surgeon, and efficient data archiving and transmission during a surgical

    Despite the significant contribution of surgical spending to health care costs, most surgeons are unaware of their operating room costs. To examine the association between providing surgeons with individualized cost feedback and surgical supply costs in the operating room. The OR Surgical Cost Reduction (OR SCORE) project was a single-health system, multihospital, multidepartmental prospective controlled study in an urban academic setting. Intervention participants were attending surgeons in orthopedic surgery, otolaryngology-head and neck surgery, and neurological surgery (n = 63). Control participants were attending surgeons in cardiothoracic surgery, general surgery, vascular surgery, pediatric surgery, obstetrics/gynecology, ophthalmology, and urology (n = 186). From January 1 to December 31, 2015, each surgeon in the intervention group received standardized monthly scorecards showing the median surgical supply direct cost for each procedure type performed in the prior month compared with the surgeon's baseline (July 1, 2012, to November 30, 2014) and compared with all surgeons at the institution performing the same procedure at baseline. All surgical departments were eligible for a financial incentive if they met a 5% cost reduction goal. The primary outcome was each group's median surgical supply cost per case. Secondary outcome measures included total departmental surgical supply costs, case mix index-adjusted median surgical supply costs, patient outcomes (30-day readmission, 30-day mortality, and discharge status), and surgeon responses to a postintervention study-specific health care value survey. The median surgical supply direct costs per case decreased 6.54% in the intervention group, from $1398 (interquartile range [IQR], $316-$5181) (10 637 cases) in 2014 to $1307 (IQR, $319-$5037) (11 820 cases) in 2015. In contrast, the median surgical supply direct cost increased 7.42% in the control group, from $712 (IQR, $202-$1602) (16 441 cases

Two hundred and twenty patientswere studied. They had been submitted to an elective orthopedic surgical procedure from July to December 1998and their medical records were used for retrospective data collection. With regard to sex, 58% were males and42% were females. As to age, middle-aged patients - 35 to 65 years old - comprised 48%, young adults - 18 to 35years old - were 38% and elderly adults - over 66 years old - were 14%. The frequency of results were as follows:surgery on the upper limbs/shoulder, 27%, knee/leg, 32%, spinal cord, 17%, femur/hips, 15%, ankle/foot, 9%,regional anesthesia, 48%, general anesthesia, 38%, regional associated with general, 6% and blocking, 8%.Occurred 306 post-operative problems were observed as follows: pain, 45%, nausea/vomiting, 16%, blooding,11%, cardiovascular alterations, 10%, hypothermia, 9%, urinary retention, 5%, respiratory problems, 1% andhiperthermia, 0,6%. In this way, there was an attempt at making a profile of orthopedic surgery patients in POI as asource of data for planning nursing care. It is believed that the study has contributed to nursing care in postanesthesiarecovery room which is based on scientific data and not only on every-day practice.

    Full Text Available Background. Sugammadex offers a good alternative to the conventional decurarisation process currently performed with cholinesterase inhibitors. Sugammadex, which was developed specifically for the aminosteroid-structured rocuronium and vecuronium neuromuscular blockers, is a modified cyclodextrin made up of 8 glucose monomers arranged in a cylindrical shape. Methods. In this study, the goal was to investigate the efficacy of sugammadex. Sugammadex was used when there was insufficient decurarisation following neostigmine. This study was performed on 14 patients who experienced insufficient decurarisation (TOF <0.9 with neostigmine after general anaesthesia in the operating rooms of a university and a state hospital between June, 2012, and January, 2014. A dose of 2 mg/kg of sugammadex was administered. Results. Time elapsed until sugammadex administration following neostigmine 37 ± 6 min, following sugammadex it took 2.1 ± 0.9 min to reach TOF ≥ 0.9, and the extubation time was 3.2 ± 1.4 min. No statistically significant differences were detected in the hemodynamic parameters before and after sugammadex application. From the time of administration of sugammadex to the second postoperative hour, no side effects or complications occurred. None of the patients experienced acute respiratory failure or residual block during this time period. Conclusion. Sugammadex was successfully used to reverse rocuronium-induced neuromuscular block in patients where neostigmine was insufficient.

    Due to surgery duration variability and arrivals of emergency surgeries, the planned Operating Room (OR) schedule is disrupted throughout the day which may lead to a change in the start time of the elective surgeries. These changes may result in undesirable situations for patients, wards or other involved departments, and therefore, the OR schedule has to be adjusted. In this paper, we develop a decision support system (DSS) which assists the OR manager in this decision by providing the three best adjusted OR schedules. The system considers the preferences of all involved stakeholders and only evaluates the OR schedules that satisfy the imposed resource constraints. The decision rules used for this system are based on a thorough analysis of the OR rescheduling problem. We model this problem as an Integer Linear Program (ILP) which objective is to minimize the deviation from the preferences of the considered stakeholders. By applying this ILP to instances from practice, we determined that the given preferences mainly lead to (i) shifting a surgery and (ii) scheduling a break between two surgeries. By using these changes in the DSS, the performed simulation study shows that less surgeries are canceled and patients and wards are more satisfied, but also that the perceived workload of several departments increases to compensate this. The system can also be used to judge the acceptability of a proposed initial OR schedule.

    Recent advances in technology have led to the introduction of a variety of innovative devices, each with their own platform for data display, into the operating room (OR). While these innovative applications are expanding the traditional boundaries of the surgical space and enhancing treatment capabilities, the introduction of additional screens and displays is placing an ever-increasing load on the OR team. This review describes the main data display platforms currently available in ORs: computer monitors with CRT (cathode ray tube) or LCD (liquid crystal display) screens, suspended imaging displays, wearable computers (WC), auditory displays and tactile (haptic) displays. The different display platforms are evaluated according to their compatibility with the characteristics of the working environment (OR), the monitoring task, and the users (the surgical team). No single display configuration provides an ultimate solution for presenting patient data in the OR. A multi-sensory data display including visual, acoustic and haptic manipulation is suggested as a promising configuration for data display in the OR.

    Ergonomics is still not fully implemented in the design of operation rooms (ORs). The OR staff has to deal with various ergonomic deficiencies which may be associated with potential hazards for the patient and/or the OR team.Three surveys were conducted among German OR staff at major conferences. Two of them dealt with the working conditions in the OR and were conducted among surgeons and OR nurses. The third survey queried OR nurses about the electrical safety in the OR.In addition, a specially developed checklist was used to evaluate the work place OR in five German OR units and the staff of these OR units were queried with questionnaires adapted from the surveys. For this article a few of the deficiencies found in the ORs were chosen to serve as examples for the plethora of results gathered.Findings showed that there was a high potential for ergonomic improvement and therefore an increase in safety and comfort. Many of these deficiencies may be eased by simple means such as the reduction of the number of different devices and mandatory training in the use of the devices since device operation is one of the main causes leading to potential hazards in the OR. Other deficiencies, such as the cable routing in the OR, require more extensive intervention and/or the implementation of new techniques, for example the "wireless" OR. All these deficiencies demonstrate the need for better implementation of ergonomics into the OR and for individual solutions, as there is no such thing as an 'one-size-fits-all' solution for OR units.

    Patient safety is foundational to neurosurgical care. Post-procedural "debrief" checklists have been proposed to improve patient safety, but there is limited data about their use in neurosurgery. Here, we implemented an initiative to routinely perform post-operative debriefs and evaluated the impact of debriefing on operating room (OR) safety culture. A 10-question safety attitude questionnaire (SAQ) was sent to neurosurgical operating room staff at a major academic medical center before and 18-months after implementation of a post-operative debriefing initiative. Rates of debrief compliance and changes in attitudes before and after the survey were evaluated. The survey utilized a Likert scale and analyzed with standard statistical methods. After the debrief initiative, the rate of debriefing increased from 51% to 86% of cases for the neurosurgery service. Baseline SAQ responses found that neurosurgeons had a more favorable perception of OR safety than anesthesiologists and nurses. Following implementation of the post-operative debriefing process, perceptions of OR safety significantly improved for neurosurgeons, anesthesiologists and nurses. Furthermore, the disparity between nurses and surgeons was no longer significant. After debrief implementation, neurosurgical OR staff had improved perceptions of patient safety compared to surgical services that did not commonly perform debriefing. Debriefing identified OR efficiency concerns in 26.9% of cases and prevention of potential adverse events/near misses were reported in 8% of cases. Post-operative debriefing can be effectively introduced into the operating room and improves the safety culture after implementation. Debriefing is an effective tool to identify OR inefficiencies and potential adverse events. Copyright © 2017 Elsevier Inc. All rights reserved.

    In business conflicts have long been known to have a negative effect on costs and team performance. In medicine this aspect has been widely neglected, especially when optimizing processes for operating room (OR) management. In the multidisciplinary setting of OR management, shortcomings in rules for decision making and lack of communication result in members perceiving themselves as competitors in the patient's environment rather than acting as art of a multiprofessional team. This inevitably leads to the emergence and escalation of conflicts. We developed a conflict matrix to provide an inexpensive and objective way for evaluating the level of escalation of conflicts in a multiprofessional working environment, such as an OR. The senior members of all involved disciplines were asked to estimate the level of conflict escalation between the individual professional groups on a scale of 0-9. By aggregating the response data, an overview of the conflict matrix within this OR section was created. No feedback was received from 1 of the 11 contacted occupational groups. By color coding the median, minimum and maximum values of the retrieved data, an intuitive overview of the escalation levels of conflict could be provided. The value range of all feedbacks was between 0 and 6. Estimation of the escalation levels differed widely within one category, showing a range of up to 6 (out of 6) levels. The presented assessment using a conflict matrix is a simple and cost-effective method to assess the conflict landscape, especially in multidisciplinary environments, such as OR management. The chance of conflict prevention or the early recognition of existing conflicts represents an enormous potential for cost and risk saving and might have positive long-term effects by building a culture of conflict prevention at the workplace and a positive influence on interdisciplinary cooperation in this working environment.

    BACKGROUND: Operating rooms (ORs), combined with labour and delivery suites, account for approximately 70% of hospital waste. Previous studies have reported that recycling can have a considerable financial impact on a hospital-wide basis; however, its importance in the OR has not been demonstrated. OBJECTIVE: To propose a method of decreasing cost through judicious selection of instruments and supplies, and initiation of recycling in plastic and hand surgery. METHODS: The authors identified disposable supplies and instruments that are routinely opened and wasted in common plastic and hand surgery procedures, and calculated the savings that can result from eliminating extraneous items. A cost analysis was performed, which compared the expense of OR waste versus single-stream recycling and the benefit of recycling HIPAA documents and blue wrap. RESULTS: Fifteen total items were removed from disposable plastic packs and seven total items from hand packs. A total of US$17,381.05 could be saved per year from these changes alone. Since initiating single-stream recycling, the authors’ institution has saved, on average, US$3,487 per month at the three campuses. After extrapolating at the current savings rate, one would expect to save a minimum of US$41,844 per year. DISCUSSION: OR waste reduction is an effective method of decreasing cost in the surgical setting. By revising the contents of current disposable packs and instrument sets designated for plastic and hand surgery, hospitals can reduce the amount of opened and unused material. CONCLUSIONS: Significant financial savings and environmental benefit can result from this judicious supply and instrument selection, as well as implementation of recycling. PMID:26665137

    OBJECTIVE Disposable supplies constitute a large portion of operating room (OR) costs and are often left over at the end of a surgical case. Despite financial and environmental implications of such waste, there has been little evaluation of OR supply utilization. The goal of this study was to quantify the utilization of disposable supplies and the costs associated with opened but unused items (i.e., "waste") in neurosurgical procedures. METHODS Every disposable supply that was unused at the end of surgery was quantified through direct observation of 58 neurosurgical cases at the University of California, San Francisco, in August 2015. Item costs (in US dollars) were determined from the authors' supply catalog, and statistical analyses were performed. RESULTS Across 58 procedures (36 cranial, 22 spinal), the average cost of unused supplies was $653 (range $89-$3640, median $448, interquartile range $230-$810), or 13.1% of total surgical supply cost. Univariate analyses revealed that case type (cranial versus spinal), case category (vascular, tumor, functional, instrumented, and noninstrumented spine), and surgeon were important predictors of the percentage of unused surgical supply cost. Case length and years of surgical training did not affect the percentage of unused supply cost. Accounting for the different case distribution in the 58 selected cases, the authors estimate approximately $968 of OR waste per case, $242,968 per month, and $2.9 million per year, for their neurosurgical department. CONCLUSIONS This study shows a large variation and significant magnitude of OR waste in neurosurgical procedures. At the authors' institution, they recommend price transparency, education about OR waste to surgeons and nurses, preference card reviews, and clarification of supplies that should be opened versus available as needed to reduce waste.

    Background Operating room (OR) human traffic has been implicated as a cause of surgical site infection. We first observed the normal human traffic pattern in our Pediatric Orthopaedic ORs, then examined the effect of surveillance on that traffic pattern. Methods This study consisted of two phases: phase I sought to observe the OR traffic pattern (number of door swings, maximum and minimum number of OR personnel, number of OR personnel at 30 minute intervals, or changes in nursing, anesthesia or surgeon staff) during surgical cases without OR personnel being notified, and for phase II, the same traffic pattern was monitored with their knowledge. Results 2442 minutes of surgical time were observed in phase I, and 1908 minutes were observed in phase II. There was no difference (p=0.06) in the time between door swings between phase I (1.39 minutes) and phase II (1.70), no difference (p=1.000) in the maximum number of people in the OR between phase I (11.5 people, range: 7–15 people) and phase II (11.5 people, range: 8–20 people), no difference (p=1.000) in the minimum number of people in the OR between phase I (4.67 people, range: 4–6 people) and phase II (4.71 people, range: 3–6 people). There was a difference in the time between door swings (p=0.03) and maximum number of people in the OR (p=0.005) based on length of surgery (less or more than120 minutes). There was no difference in the time between door swings (p=0.11), but there was a difference in the maximum number of people in the OR (p=0.002) based on type of surgery (spine vs. others). Conclusion There was no role of surveillance of human traffic in the OR. To achieve any change in the OR traffic pattern, monitoring alone may not be sufficient; other novel techniques or incentives may need to be considered. PMID:20733430

    Increased clinician workload is associated with medical errors and patient harm. The Quality and Workload Assessment Tool (QWAT) measures anticipated (pre-case) and perceived (post-case) clinical workload during actual surgical procedures using ratings of individual and team case difficulty from every operating room (OR) team member. The purpose of this study was to examine the QWAT ratings of OR clinicians who were not present in the OR but who read vignettes compiled from actual case documentation to assess interrater reliability and agreement with ratings made by clinicians involved in the actual cases. Thirty-six OR clinicians (13 anesthesia providers, 11 surgeons, and 12 nurses) used the QWAT to rate 6 cases varying from easy to moderately difficult based on actual ratings made by clinicians involved with the cases. Cases were presented and rated in random order. Before rating anticipated individual and team difficulty, the raters read prepared clinical vignettes containing case synopses and much of the same written case information that was available to the actual clinicians before the onset of each case. Then, before rating perceived individual and team difficulty, they read part 2 of the vignette consisting of detailed role-specific intraoperative data regarding the anesthetic and surgical course, unusual events, and other relevant contextual factors. Surgeons had higher interrater reliability on the QWAT than did OR nurses or anesthesia providers. For the anticipated individual and team workload ratings, there were no statistically significant differences between the actual ratings and the ratings obtained from the vignettes. There were differences for the 3 provider types in perceived individual workload for the median difficulty cases and in the perceived team workload for the median and more difficult cases. The case difficulty items on the QWAT seem to be sufficiently reliable and valid to be used in other studies of anticipated and perceived clinical

    Monolithic lasers on Si are ideal for high-volume and large-scale electronic-photonic integration. Ge is an interesting candidate owing to its pseudodirect gap properties and compatibility with Si complementary metal oxide semiconductor technology. Recently we have demonstrated room-temperature photoluminescence, electroluminescence, and optical gain from the direct gap transition of band-engineered Ge-on-Si using tensile strain and n-type doping. Here we report what we believe to be the first experimental observation of lasing from the direct gap transition of Ge-on-Si at room temperature using an edge-emitting waveguide device. The emission exhibited a gain spectrum of 1590-1610 nm, line narrowing and polarization evolution from a mixed TE/TM to predominantly TE with increasing gain, and a clear threshold behavior.

    Full Text Available The laminar flow air-conditioning system with 100% fresh air is used in almost all operating rooms without discrimination in Turkey. The laminar flow device which is working with 100% fresh air should be absolutely used in Type 1A operating rooms. However, there is not mandatory to use of 100% fresh air for Type 1B defined as places performed simpler operation. Compared with recirculating laminar flow, energy needs of the laminar flow with 100 % fresh air has been emerged about 40% more than re-circulated air flow. Therefore, when a recirculating laminar flow device is operated instead of laminar flow system with 100% fresh air in the Type 1B operating room, annual energy consumption will be reduced. In this study, in an operating room with recirculating laminar flow, optimal conditions have been investigated in order to obtain laminar flow form by analyzing velocity distributions at various supply velocities by using computational fluid dynamics method (CFD.

    Full Text Available This research has been carried out in order to determine anger expression and anger management styles in operating room nurses. By applying an in-depth interview technique on operating room nurses working in a private hospital, a qualitative study has been performed in order to determine anger expression and anger management styles in operating room nurses. The interview consisted of ten questions such as demographic questions addressing the workers’ age, sex, education level and duration of employment in the organization they work, aiming to determine their anger expression and anger management styles. Since operating room environments contain various risk factors, and require active team work in a stressful dynamic setting under excessive workload, , it has been found that operating room nurses display their anger through loud speaking, fail to settle their anger positively, fail to control their anger in a behavioural pattern despite their cognitive awareness in anger management. Thus, it has been suggested that operating room nurses should be trained on anger management methods so that they can manage their anger in a stressful operating room environment.

    Students undertake their clinical placement in various clinical settings for the exposure to and acquisition of skills related to that particular context. The operating room is a context that offers the opportunity to develop critical skills related to the perioperative care of the patient. Despite numerous studies that have been undertaken in this field, few have investigated the operating room as a clinical learning environment in the South African private healthcare context. The aim of this study was to determine nursing students' perceptions of the operating room as a clinical learning environment. An exploratory, interpretive and descriptive design generating qualitative data was utilized. Eight nursing students completed an open-ended questionnaire, and twelve nursing students participated in the focus group discussion. Four themes emerged, namely, 'interpersonal factors', 'educational factors', 'private operating room context', and 'recommendations'. The opinion that the operating room offers an opportunity to gain skills unique to this context was expressed. However, despite the potential learning opportunities, the key findings of this study reveal negative perceptions of nursing students regarding learning experiences in the operating room. Exploration into the preparatory needs of students specific to learning outcomes before operating room placement should be considered. It will also be necessary to improve collaboration between lecturers, mentors and theatre managers.

    High usage rate in a surgical suite is extremely important in meeting the increasing demand for health care services and reducing costs to improve quality of care. In this paper a goal programming model which can produce schedules that best serve the needs of the hospital, i.e., by minimizing idle time and overtime, and increasing satisfaction of surgeons, patients, and staff, is described. The approach involves sorting the requests for a particular day on the basis of block restrictions, room utilization, surgeon preferences and intensive care capabilities. The model is tested using the data obtained during field studies at Dokuz Eylul University Hospital. The model is also tested for alternative achievement functions to examine the model's ability to satisfy abstract goals.

    The balance between reducing costs and inefficiencies with that of patient safety is a challenging problem faced in the operating room suite. An ongoing challenge is the creation of effective strategies that reduce these inefficiencies and provide real-time personalized metrics and electronic feedback to anesthesia practitioners. We created a sample report card structure, utilizing existing informatics systems. This system allows to gather and analyze operating room metrics for each anesthesia provider and offer personalized feedback. To accomplish this task, we identified key metrics that represented time and quality parameters. We collected these data for individual anesthesiologists and compared performance to the overall group average. Data were presented as an electronic score card and made available to individual clinicians on a real-time basis in an effort to provide effective feedback. These metrics included number of cancelled cases, average turnover time, average time to operating room ready and patient in room, number of delayed first case starts, average induction time, average extubation time, average time to recovery room arrival to discharge, performance feedback from other providers, compliance to various protocols, and total anesthetic costs. The concept we propose can easily be generalized to a variety of operating room settings, types of facilities and OR health care professionals. Such a scorecard can be created using content that is important for operating room efficiency, research, and practice improvement for anesthesia providers.

    The digital operating-room, with highly integrated clinical information, is very important for rescuing lives of patients and improving quality of operations. Since equipments in domestic operating-rooms have diversified interface and nonstandard communication protocols, designing and implementing an integrated data sharing program for different kinds of diagnosing, monitoring, and treatment equipments become a key point in construction of digital operating room. This paper addresses interface interconnection and data integration for commonly used clinical equipments from aspects of hardware interface, interface connection and communication protocol, and offers a solution for interconnection and integration of clinical equipments in heterogeneous environment. Based on the solution, a case of an optimal digital operating-room is presented in this paper. Comparing with the international solution for digital operating-room, the solution proposed in this paper is more economical and effective. And finally, this paper provides a proposal for the platform construction of digital perating-room as well as a viewpoint for standardization of domestic clinical equipments.

    A workflow-driven cooperative operating room needs to be established in order to successfully unburden the surgeon and the operating room staff very time-consuming information-seeking and configuration tasks. We propose an approach towards the integration of intraoperative surgical workflow management and integration technologies. The concept of rule-based behavior is adapted to situation-aware medical devices. A prototype was implemented and experiments with sixty recorded brain tumor removal procedures were conducted to test the proposed approach. An analysis of the recordings indicated numerous applications, such as automatic display configuration, room light adaptation and pre-configuration of medical devices and systems.

    Hospitals face growing pressure to meet the dual but often competing goals of providing a safe environment while controlling operating costs. Evidence-based data are needed to provide insight for facility management practices to support these goals. The quality of the air in 3 operating rooms was measured at different ventilation rates. The energy cost to provide the heating, ventilation, and air conditioning to the rooms was estimated to provide a cost-benefit comparison of the effectiveness of different ventilation rates currently used in the health care industry. Simply increasing air change rates in the operating rooms tested did not necessarily provide an overall cleaner environment, but did substantially increase energy consumption and costs. Additionally, and unexpectedly, significant differences in microbial load and air velocity were detected between the sterile fields and back instrument tables. Increasing the ventilation rates in operating rooms in an effort to improve clinical outcomes and potentially reduce surgical site infections does not necessarily provide cleaner air, but does typically increase operating costs. Efficient distribution or management of the air can improve quality indicators and potentially reduce the number of air changes required. Measurable environmental quality indicators could be used in lieu of or in addition to air change rate requirements to optimize cost and quality for an operating room and other critical environments.

    2015-01-01

    Full Text Available The operation theater (OT environment is the most complex and volatile workplace where two coequal physicians share responsibility of one patient. Difference in information, opinion, values, experience and interests between a surgeon and anesthesiologist may arise while working in high-pressure environments like OT, which may trigger conflict. Quality of patient care depends on effective teamwork for which multidisciplinary communication is an essential part. Troubled relationships leads to conflicts and conflicts leads to stressful work environment which hinders the safe discharge of patient care. Unresolved conflicts can harm the relationship but when handled in a positive way it provides an opportunity for growth and ultimately strengthening the bond between two people. By learning the skills to resolve conflict, we can keep our professional relationship healthy and strong which is an important component of good patient care.

  9. Operating room use of hypertonic solutions: a clinical review

    Gustavo Azoubel

    2008-01-01

    Full Text Available Hyperosmotic-hyperoncotic solutions have been widely used during prehospital care of trauma patients and have shown positive hemodynamic effects. Recently, there has been a growing interest in intra-operative use of hypertonic solutions. We reviewed 30 clinical studies on the use of hypertonic saline solutions during surgeries, with the majority being cardiac surgeries. Reduced positive fluid balance, increased cardiac index, and decreased systemic vascular resistance were the main beneficial effects of using hypertonic solutions in this population. Well-designed clinical trials are highly needed, particularly in aortic aneurysm repair surgeries, where hypertonic solutions have shown many beneficial effects. Examining the immunomodulatory effects of hypertonic solutions should also be a priority in future studies.

    2016-12-01

    This article reports the results of a case study of the consequences of mobile device use for the work practices of operating room nurses. The study identifies different patterns of mobile technology use by operating room nurses, including both work-related and non-work-related use. These patterns have multiple consequences for nurses, such as improvements in information access, e-learning and work-related communication, as well as a perceived increase in distractions from the collaborative work. We conceptualize these consequences in terms of three level effects and explain how we find both positive and negative consequences on the third level. On the positive side, improvements were found in how nurses spent their unoccupied time during the stable parts of operations, contributing to their well-being and job satisfaction. A negative consequence was the perceived increase in distraction from the collaborative operating room work practices.

    Miller, Anya J; Gardner, Glendon M

    2017-01-01

    We conducted a study to analyze hospital and patient costs, outcomes, and patient satisfaction among adults undergoing in-office and operating room procedures for the treatment of recurrent respiratory papillomatosis. Our final study population was made up of 17 patients-1 man and 16 women, aged 30 to 86 years (mean: 62). The mean number of in-office laser procedures per patient was 4.2, and the mean interval between procedures was 5.4 months (although 10 patients underwent only 1 office procedure); the mean number of operating room procedures was 13.5, and the mean interval between procedures was 14.3 months. An equal number of patients reported complications or adverse events with the two types of procedures-5 each. The difference in cost between the office procedure (mean: $3,413.00) and the operating room procedure (mean: $12,382.59) was almost $9,000, but these savings were offset by the fact that the office procedures needed to be performed three times as often. Patients reported slightly more anxiety and discomfort during the office procedures and, overall, they appeared to prefer the operating room procedure. We conclude that office procedures are significantly more cost-effective than operating room procedures, but their use may be limited by patient tolerance and the increased frequency of the procedure.

    2016-09-01

    Full Text Available BACKGROUND Hand washing has been considered a measure of personal hygiene for centuries and it is known that an improper hand hygiene by healthcare workers is responsible for about 40% of nosocomial infections. Therefore, surgical hand preparation is a critical element for healthcare safety in order to reduce microbial contamination of  surgical wound in case of non detected break of the gloves. The aim of our study is to evaluate the efficacy three antiseptics: Povi-iodine scrub; EPG (Ethanol, Hydrogen Peroxide, Glycerol, recommended by WHO, and common marseille soap type in a liquid formulation. METHODS It was designed a randomized, double-blind, single-center study conducted in the University Hospital of Messina, from January to June 2013. We asked operators to put the fingertips of their right hand (if not left-handed for one minute on the PCA medium, before washing with the three types of antiseptics, and after washing and drying. Drying was made using sterile gauzes or disposable wipes. Then, we measured the number of colony forming units per mL (CFU/mL and calculated the percentage of microbial load reduction. RESULTS 211 samples have been considered for statistical analysis: in 42 samples, in fact, initial microbial load was lower than after washing. Washing with EPG reduced CFU/ml from  a mean of 38,9 to 4,1 (86,5% reduction, washing with povi-iodine scrub from 59,55 to 12,9 (75,9% reduction and washing with Marseille soap from 47,26 to 12,7 (64,3% reduction. CONCLUSIONS Our study shows that washing with EPG has superior efficacy in CFU reduction. Antiseptic hand washing, however, cannot be considered the only measure to reduce infections: the anomaly of some results (initial microbial load lower than after washing  demonstrates that drying is an essential phase in the presurgical preparation. Therefore, hand hygiene must be part of a more complex strategy of surveillance and control of nosocomial infections

    The ergonomic design in the Surgical OR of information technology systems has been and continues to be a large problem. Numerous disparate information systems with unique hardware and display configurations create an environment similar to the chaotic environments of air traffic control. Patient information systems tend to show all available statistics making it difficult to isolate the key, relevant vitals for the patient. Interactions in this sterile environment are still being done with the traditional keyboard and mouse designed for cubicle office workflows. This presentation will address the shortcomings of the current design paradigm in the Surgical OR that relate to Information Technology systems. It will offer a perspective that addresses the ergonomic deficiencies and predicts how future technological innovations will integrate into this vision. Part of this vision includes a Surgical OR PACS prototype, developed by GE Healthcare Technologies, that addresses ergonomic challenges of PACS in the OR that include lack of portability, sterile field integrity, and UI targeted for diagnostic radiologists. GWindows (gesture control) developed by Microsoft Research and Voice command will allow for the surgeons to navigate and review diagnostic imagery without using the conventional keyboard and mouse that disrupt the integrity of the sterile field. This prototype also demonstrates how a wireless, battery powered, self contained mobile PACS workstation can be optimally positioned for a surgeon to reference images during an intervention as opposed to the current pre-operative review. Lessons learned from the creation of the Surgical OR PACS Prototype have demonstrated that PACS alone is not the end all solution in the OR. Integration of other disparate information systems and presentation of this information in simple, easy to navigate information packets will enable smoother interactions for the surgeons and other healthcare professionals in the OR.

    Full Text Available Aim: to conduct a comparative analysis of the psychological characteristics of the most and least successful main control room operators. Material and Methods. Two NPP staff groups: the most and least successful main control room operators, who worked in routine operating conditions, were surveyed. Expert evaluation method has been applied to identify the groups. The subjects were administered the Minnesota Multiphasic Personality Inventory (MMPI, Cattell's Sixteen Personality Factor Questionnaire (16PF form A and Raven's Progressive Matrices test. Results. Numerous significant psychological differences between the groups of most and least successful control room operators were obtained: the best operators were significantly more introverted and correctly solved more logical tasks with smaller percentage of mistakes under time pressure than worst ones. Conclusions: 1. The psychodiagnostic methods used in the study were adequate to meet research objective 2. Tendency to introversion, as well as developed the ability to solve logic problems undertime pressure, apparently, are important professional qualities for control room operators. These indicators should be considered in the process of psychological selection and professional guidance of nuclear power plant operators.

    Operating room (OR) managers must plan staffing in the face of uncertain demand for OR time. Planning too much staffing results in underutilized OR time. Planning too little staffing causes overutilized time, which is approximately twice as expensive as underutilized time. Deciding how much staffing to plan for an OR is analogous to the classic newsvendor problem in operations research. A newsvendor must decide how much product to order based on its cost c and sales price p, plus estimates of the uncertain future demand for the product. The newsvendor problem has a simple mathematical solution. The correct amount of product to order is the (p - c)/p quantile of the demand for the product. This optimal order quantity is analogous mathematically to the number of hours of OR time for which staffing should be planned. We performed a systematic review of the behavioral operations experimental literature on newsvendor problems relevant to OR management. Student volunteers participating in experimental studies have great difficulty knowing how much product to order, given c, p, and the demand distribution. Decision making is only modestly improved by more frequent feedback. Even scores of rounds of ordering are insufficient for much learning to occur. Suboptimal decisions result from innate psychological biases. Students anchor on mean demand, make insufficient adjustments, and rely disproportionately on the most recent demand values. The behavior of OR managers who plan staffing for the OR is analogous to that of students participating in a newsvendor experiment. Month after month, an OR manager will plan too little staffing for the surgeon who consistently ends the day late and too much staffing for the surgeon who consistently does not fill an OR. Experimental studies of the newsvendor problem provide mechanistic insights into the reasons that OR managers make poor decisions when planning OR staffing. The students face no organizational factors or personality issues

    2015-06-01

    A mobile operating room information management system with electronic medical record (EMR) is designed to improve work efficiency and to enhance the patient information sharing. In the operating room, this system acquires the information from various medical devices through the Client/Server (C/S) pattern, and automatically generates XML-based EMR. Outside the operating room, this system provides information access service by using the Browser/Server (B/S) pattern. Software test shows that this system can correctly collect medical information from equipment and clearly display the real-time waveform. By achieving surgery records with higher quality and sharing the information among mobile medical units, this system can effectively reduce doctors' workload and promote the information construction of the field hospital.

    Full Text Available Abstract Background Patient safety is one of the greatest challenges in healthcare. In the operating room errors are frequent and often consequential. This article describes an approach to a successful implementation of a patient safety program in the operating room, focussing on latent risk factors that influence patient safety. We performed an intervention to improve these latent risk factors (LRFs and increase awareness of patient safety issues amongst OR staff. Methods Latent risk factors were studied using a validated questionnaire applied to the OR staff before and after an intervention. A pre-test/post-test control group design with repeated measures was used to evaluate the effects of the interventions. The staff from one operating room of an university hospital acted as the intervention group. Controls consisted of the staff of the operating room in another university hospital. The outcomes were the changes in LRF scores, perceived incident rate, and changes in incident reports between pre- and post-intervention. Results Based on pre-test scores and participants’ key concerns about organizational factors affecting patient safety in their department the intervention focused on the following LRFs: Material Resources, Training and Staffing Recourses. After the intervention, the intervention operating room - compared to the control operating room - reported significantly fewer problems on Material Resources and Staffing Resources and a significantly lower score on perceived incident rate. The contribution of technical factors to incident causation decreased significantly in the intervention group after the intervention. Conclusion The change of state of latent risk factors can be measured using a patient safety questionnaire aimed at these factors. The change of the relevant risk factors (Material and Staffing resources concurred with a decrease in perceived and reported incident rates in the relevant categories. We conclude that

    Full Text Available In recent years, approaches for information and control integration in the digital operating room have emerged. A major step towards an intelligent operating room and a cooperative technical environment would be autonomous adaptation of medical devices and systems to the surgical workflow. The OR staff should be freed from information seeking and maintenance tasks. We propose a closed-loop concept integrating workflow monitoring, processing and (semi-automatic interaction to bridge the gap between OR integration of medical devices and workflow-related information management.

    Pharmaceutical services implemented in an operating room (OR) pharmacy substation without addition of staff in a 764-bed teaching hospital with 22 operating rooms are described. In 1984 an interdepartmental task force recommended that pharmacy take control of responsibility for controlled drugs used in anesthesia. The anesthesia department contributed space for a pharmacy substation and some of the necessary equipment. Two technicians staff the substation (1.5 full-time equivalent positions); pharmacy contributed 0.5 FTE and the additional FTE was obtained through staffing adjustments in other departments. Anesthesiologists and nurse anesthetists obtain controlled drugs directly from the technicians, and records of drug disposition are compared with inventory twice daily. The substation also handles exchange carts for noncontrolled drugs for anesthesia and for other drugs used in the operating rooms. Total cost (additional cost to pharmacy and other departments) for operating the substation for its first year was +2161, and there were no unresolved discrepancies in controlled drug accounting. Undocumented use of noncontrolled drugs has been reduced by 67%, and cooperation and communication between the pharmacy and anesthesia departments has improved. Substation personnel do not prepare intravenous admixtures or provide clinical services. An operating room substation staffed by technicians 10.5 hours daily Monday through Friday provided cost-effective pharmacy control of drugs used in the OR.

    To evaluate operating room nurses' perception of teamwork performance and their level of mental stress and to identify related factors. Little is known about the factors affecting teamwork and the mental stress of surgical nurses, although the performance of the surgical team is essential for patient safety. The questionnaire survey for operation room nurses consisted of simple questions about teamwork performance and mental stress. Multivariate analyses were used to identify factors causing a sense of teamwork performance or mental stress. A large number of surgical nurses had a sense of teamwork performance, but 30-40% of operation room nurses were mentally stressed during surgery. Neither the patient nor the operation factors were related to the sense of teamwork performance in both types of nurses. Among scrub nurses, endoscopic and abdominal surgery, body mass index, blood loss and the American Society of Anesthesiologists physical status class were related to their mental stress. Conversely, circulating nurses were stressed about teamwork performance. The factors related to teamwork performance and mental stress during surgery differed between scrub and circulating nurses. Increased support for operation room nurses is necessary. The increased support leads to safer surgical procedures and better patient outcomes. © 2017 John Wiley & Sons Ltd.

    Teamwork is an important component of patient safety. In fact, communication errors are the most common cause of sentinel events and wrong-site operations in the US. Although efforts to improve patient safety through improving teamwork are growing, there is no validated tool to scientifically measure teamwork in the surgical setting. Operating room personnel in 60 hospitals were surveyed using the Safety Attitudes Questionnaire. Surgeons, anesthesiologists, certified registered nurse anesthetists, and operating room nurses rated their own peers and each other using a 5-point Likert scale (1 = very low, 5 = very high). Overall response rate was 77.1% (2,135 of 2,769). Ratings of teamwork differed substantially by operating room caregiver type, with the greatest differences in ratings shown by physicians: surgeons (F[4, 2058] = 41.73, p teamwork exist in the operating room, with physicians rating the teamwork of others as good, but at the same time, nurses perceive teamwork as mediocre. Given the importance of communication and collaboration in patient safety, health care organizations should measure teamwork using a scientifically valid method. The Safety Attitudes Questionnaire can be used to measure teamwork, identify disconnects between or within disciplines, and evaluate interventions aimed at improving patient safety.

    The leakage radiation characteristics of a dedicated intraoperative radiotherapy linear accelerator have been measured on a machine designed to minimize the shielding required to allow it to be placed in an operating room suite. The scattering foil design was optimized to produce a flat beam for the field sizes employed while generating minimal bremsstrahlung contamination over the available energy range. More lead shielding was used in the treatment head than is used in conventional accelerators. A small amount of borated polyethylene shielding was also employed since neutron production was present at measurable levels. The room shielding installed in the operating room was demonstrated to be adequate to treat at least 20 patients each month to an average dose of 20 Gy. The worst case exposure was found to be 73% maximum permissible exposure. Administrative control was required for adjoining areas when calibrations and maintenance were performed.

    The Boston Marathon terrorist bombing that occurred on April 15, 2013 illustrates the importance of a cohesive, efficient management for the operating room and perioperative services. Conceptually, emotional intelligence (EI) is a form of social intelligence used by individuals in leadership positions to monitor the feelings and emotions of their team while implementing a strategic plan. To describe the experience of caring for victims of the bombing at a large tertiary care center and provide examples demonstrating the importance of EI and its role in the management of patient flow and overall care. A retrospective review of trauma data was performed. Data regarding patient flow, treatment types, treatment times, and outcomes were gathered from the hospital's electronic tracking system and subsequently analyzed. Analyses were performed to aggregate the data, identify trends, and describe the medical care. Immediately following the bombing, a total of 35 patients were brought to the emergency department (ED) with injuries requiring immediate medical attention. 10 of these patients went directly to the operating room on arrival to the hospital. The first victim was in an operating room within 21 minutes after arrival to the ED. The application of EI in managerial decisions helped to ensure smooth transitions for victims throughout all stages of their perioperative care. EI provided the fundamental groundwork that allowed the operating room manager and nurse leaders to establish the calm and coordinated leadership that facilitated patient care and teamwork.

    Full Text Available Hypersensitivity reactions to natural rubber latex have increased recently, especially among people with high exposure to latex allergens. Hypersensitivity reactions to latex are related to many conditions like occupational asthma. Our study was performed to determine the prevalence of hypersensitivity to natural rubber latex and potential food cross reactions in operation room personnel in Shiraz hospitals. In this cross-sectional, descriptive study, 580 operation room personnel filled out our questionnaire which included data about their personal history, symptoms of latex hypersensitivity, and other related allergies such as food hypersensitivity. An informed consent was obtained and skin prick tests were performed for natural rubber latex and potential food cross reactions (kiwi, banana, and potato. The obtained data were analyzed by SPSS and Chi-square test.Results: 104 (17.9% of the operating room personnel showed positive latex skin tests. We revealed a significant correlation between those with positive skin tests to latex with atopia, urthicaria, and food hypersensitivity. The prevalence did not vary by sex, age, education, surgical and non-surgical gloves users, or history of contact dermatitis. Latex hypersensitivity is common among operation room personnel. Evaluation of symptoms and prediction of future diseases necessitate screening tests in individuals at risk.

    Sufficient quantities of quality air and controlled, unidirectional flow are important elements in providing a safe building environment for operating rooms. To make dynamic assessments of an operating room environment, a validated method of testing the multiple factors influencing the air quality in health care settings needed to be constructed. These include the following: temperature, humidity, particle load, number of microbial contaminants, pressurization, air velocity, and air distribution. The team developed the name environmental quality indicators (EQIs) to describe the overall air quality based on the actual measurements of these properties taken during the mock surgical procedures. These indicators were measured at 3 different hospitals during mock surgical procedures to simulate actual operating room conditions. EQIs included microbial assessments at the operating table and the back instrument table and real-time analysis of particle counts at 9 different defined locations in the operating suites. Air velocities were measured at the face of the supply diffusers, at the sterile field, at the back table, and at a return grille. The testing protocol provided consistent and comparable measurements of air quality indicators between institutions. At 20 air changes per hour (ACH), and an average temperature of 66.3°F, the median of the microbial contaminants for the 3 operating room sites ranged from 3-22 colony forming units (CFU)/m(3) at the sterile field and 5-27 CFU/m(3) at the back table. At 20 ACH, the median levels of the 0.5-µm particles at the 3 sites were 85,079, 85,325, and 912,232 in particles per cubic meter, with a predictable increase in particle load in the non-high-efficiency particulate air-filtered operating room site. Using a comparison with cleanroom standards, the microbial and particle counts in all 3 operating rooms were equivalent to International Organization for Standardization classifications 7 and 8 during the mock surgical

    Obesity has become a major epidemic in the United States. Although research suggests obesity does not increase major morbidity or mortality after thoracic operations, it likely results in greater use of health care resources. We examined all patients in The Society of Thoracic Surgeons General Thoracic Surgery database with primary lung cancer who underwent lobectomy from 2006 to 2010. We investigated the impact of body mass index (BMI) on total operating room time using a linear mixed-effects regression model and multiple imputations to account for missing data. Secondary outcomes included postoperative length of stay and 30-day mortality. Covariates included age, sex, race, forced expiratory volume, smoking status, Zubrod score, prior chemotherapy or radiation, steroid use, number of comorbidities, surgical approach, hospital lobectomy volume, hospital percent obesity, and the addition of mediastinoscopy or wedge resection. A total of 19,337 patients were included. The mean BMI was 27.3 kg/m2, with 4,898 patients (25.3%) having a BMI of 30 kg/m2 or greater. The mean total operating room time, length of stay, and 30-day mortality were 240 minutes, 6.7 days, and 1.8%, respectively. For every 10-unit increase in BMI, mean operating room time increased by 7.2 minutes (range, 4.8 to 8.4 minutes; pobese patients did not affect the association between BMI and operative time. Body mass index was not associated with 30-day mortality or increased length of stay. Increased BMI is associated with increased total operating room time, regardless of institutional experience with obese patients. Copyright © 2012 The Society of Thoracic Surgeons.

    The introduction of innovative drugs in anesthesiological treatment has the potential to improve perioperative efficiency. This article examines the impact of the new muscle relaxant encapsulator Bridion on emergence from anesthesia and on the efficiency of the perioperative organization. To analyze the effects of medical innovations, computer simulation was used as an experimental frame. The simulation was based on a realistic model of an operating room setting and used historical data to study the effect of innovation on the operational performance and the economic outcomes. The use of medical innovations in anesthesiological emergence yields new potentials for a hospital under certain conditions. Due to shorter block times and anesthesia-controlled times, additional benefits for the operating room could be realized. This results in an increase of up to 2.4% additional cases during similar working hours and planning periods. The introduction of innovative medicines may reveal more efficient and economical conditions in operating rooms. The overall result depends, for example, on the rate of application of the patient's portfolio or the organization and access rules of the surgical suite. Based on the anesthesia-controlled time no general a priori statement about the economic potentials can be confirmed. Future empirical studies should investigate the impact on quality and economic benefits for the entire patient pathway.

    The aim of this research was to determine if guided operating theatre experience in the undergraduate nursing curricula enhanced surgical knowledge and understanding of nursing care provided outside this specialist area in the pre- and post-operative surgical wards. Using quantitative analyses, undergraduate nurses were knowledge tested on areas of pre- and post-operative surgical nursing in their final semester of study. As much learning occurs in nurses' first year of practice, participants were re-tested again after their Graduate Nurse Program/Preceptorship year. Participants' results were compared to the model of operating room education they had participated in to determine if there was a relationship between the type of theatre education they experienced (if any) and their knowledge of surgical ward nursing. Findings revealed undergraduates nurses receiving guided operating theatre experience had a 76% pass rate compared to 56% with non-guided or no experience (p < 0.001). Graduates with guided operating theatre experience as undergraduates or graduate nurses achieved a 100% pass rate compared to 53% with non-guided or no experience (p < 0.001). The research informs us that undergraduate nurses achieve greater learning about surgical ward nursing via guided operating room experience as opposed to surgical ward nursing experience alone.

    The main bottlenecks limiting the practical applications of current magnetoresistive random access memory (MRAM) technology are its low storage density and high writing energy consumption. Although a number of proposals have been reported for voltage-controlled memory device in recent years, none of them simultaneously satisfy the important device attributes: high storage capacity, low power consumption and room temperature operation. Here we present, using phase-field simulations, a simple and new pathway towards high-performance MRAMs that display significant improvements over existing MRAM technologies or proposed concepts. The proposed nanoscale MRAM device simultaneously exhibits ultrahigh storage capacity of up to 88 Gb inch(-2), ultralow power dissipation as low as 0.16 fJ per bit and room temperature high-speed operation below 10 ns.

    It is desirable to maintain a low bacterial count in the operating room air to prevent surgical site infection. This can be achieved by ventilation or by all staff in the operating room wearing clothes made from low-permeable material (i.e. clean air suits). We investigated whether there was a difference in protective efficacy between a single-use clothing system made of polypropylene and a reusable clothing system made of a mixed material (cotton/polyester) by testing both in a dispersal chamber and during surgical procedures. Counts of colony-forming units (cfu)/m(3) air were significantly lower when using the single-use clothing system in both settings. Copyright © 2013 The Healthcare Infection Society.

    We have designed a mobile operating room information management system. The system is composed of a client and a server. A client, consisting of a PC, medical equipments, PLC and sensors, provides the acquisition and processing of anesthesia and micro-environment data. A server is a powerful computer that stores the data of the system. The client gathers the medical device data by using the C/S mode, and analyzes the obtained HL7 messages through the class library call. The client collects the micro-environment information with PLC, and finishes the data reading with the OPC technology. Experiment results showed that the designed system could manage the patient anesthesia and micro-environment information well, and improve the efficiency of the doctors' works and the digital level of the mobile operating room.

    Describe the surgical training of gynecologic residents in the operating room, by collecting the opinion of French gynecologists. A questionnaire investigating this subject was put on a web site. Every French gynecologist could answer the questionnaire from a duration of six months. The data of the inquiry were studied by comparing five groups: residents (group 1), fellows (group 2), seniors of public hospital (group 3), and seniors of private hospitals (group 4), or, groups 2, 3 and 4 together, as Group A. Six hundred and fifty-seven gynecologists answered the inquiry. For the residents, lack of time and senior's weak educational motivation are the explanations most frequently retained in order to explain that residents do not operate. For group A, it is rather the residents' skills which is the most important fact to have residents operate. Residents more often practice surgery in general public hospital that in faculty hospital. For 31% of all the referees, heads of departments do not incite their teams to have residents operate. Nearly 25% of all the investigated believe that a man operates more than a woman in resident curriculum. Besides, by analyzing the answers of groups 1 and 2, we were able to correlate resident seniority at their first practice of 13 surgical operations. For 26% of the group A, residents operate less than they do during their own studies. Finally, all the investigated confirm the lack of surgical assessment in the resident curriculum. Decision to let the resident operate remains too dependent on senior personal appreciation and does not seem to join a strategy of training. Opinions of surgical training in the operating room is different between residents and seniors. Operating time increases when residents operate but there is no effect on quality of care. These results show again the necessity of a formal teaching and assessment, in a resident program with objectives, collecting every resident's surgery volume. These educational

    2015-07-01

    Full Text Available Introduction: Chamomile tea (CT is an herbal tea and is served as a beneficial herbal infusion all over the world. Its major polyphenols constituents and tea-catechins have been shown to have health benefits. Operating room staff are commonly exposed to damaging factors, such as radiation, waste anesthetic gases and psychological stress. One of the most important qualities of CT is its antioxidant property. The aim of this study was to evaluate the effects of CT in reducing the oxidative stress of operative room staff that are chronically exposed to damaging factors. Methods: In this study we approached to 20 operating room personnel. The subjects drank 2 cups of CT (every cup contained 1.8730 g of chamomile and 300 ml of water daily, one cup in the morning and another in the afternoon for 21 days. A questionnaire that contained personal information was filled by each subject. Oxidative stress parameters such as total antioxidant capacity (TAC, catalase (CAT and total thiol molecules (TTG were measured 2 times: first before drinking CT at the first day and the next time after the 21st day. Results: Consumption of CT by subjects caused a significant induction in TAC (6.62 ± 0.77 vs 4.81± 0.39 ųmol/ml, P < .05 of saliva. There was not any statistically significant change in saliva TTG and CAT after 21 days of drinking CT. Conclusion: In the end we came to conclusion that CT can be a useful additional food to remove the oxidative damage that happens to operating room staff.

    Occasionally, surgeons do need various types of information to be available rapidly, efficiently and safely during surgical procedures. Meanwhile, they need to free up hands throughout the surgery to necessarily access the mouse to control any application in the sterility mode. In addition, they are required to record audio as well as video files, and enter and save some data. This is an attempt to develop a comprehensive operating room information system called "Medinav" to tackle all mentioned issues. An integrated and comprehensive operating room information system is introduced to be compatible with Health Level 7 (HL7) and digital imaging and communications in medicine (DICOM). DICOM is a standard for handling, storing, printing, and transmitting information in medical imaging. Besides, a natural user interface (NUI) is designed specifically for operating rooms where touch-less interactions with finger and hand tracking are in use. Further, the system could both record procedural data automatically, and view acquired information from multiple perspectives graphically. A prototype system is tested in a live operating room environment at an Iranian teaching hospital. There are also contextual interviews and usability satisfaction questionnaires conducted with the "MediNav" system to investigate how useful the proposed system could be. The results reveal that integration of these systems into a complete solution is the key to not only stream up data and workflow but maximize surgical team usefulness as well. It is now possible to comprehensively collect and visualize medical information, and access a management tool with a touch-less NUI in a rather quick, practical, and harmless manner.

    The aim of this study was to evaluate the stress levels and stress coping strategies of nursing students in their first operating room experience. This descriptive study was done with 126 nursing students who were having an experience in an operating room for the first time. Data were collected by using Personal Information Form, Clinical Stress Questionnaire, and Styles of Coping Inventory. The nursing students mostly had low clinical stress levels (M = 27.56, SD = 10.76) and adopted a self-confident approach in coping with stress (M = 14.3, SD = 3.58). The nursing students generally employed a helpless/self-accusatory approach among passive patterns as their clinical stress levels increased, used a self-confident and optimistic approach among active patterns as their average age increased, and those who had never been to an operating room previously used a submissive approach among passive patterns. The results showed that low levels of stress caused the nursing students to use active patterns in coping with stress, whereas increasing levels of stress resulted in employing passive patterns in stress coping. The nursing students should be ensured to maintain low levels of stress and use active patterns in stress coping.

  13. Building a Smooth Medical Service for Operating Room Using RFID Technologies

    Full Text Available Due to the information technology advancement, the feasibility for the establishment of mobile medical environments has been strengthened. Using RFID to facilitate the tracing of patients’ mobile position in hospital has attracted more attentions from researchers due to the demand on advanced features. Traditionally, the management of surgical treatment is generally manually operated and there is no consistent operating procedure for patients transferring among wards, surgery waiting rooms, operating rooms, and recovery rooms, resulting in panicky and urgent transferring work among departments and, thus, leading to delays and errors. In this paper, we propose a new framework using radio frequency identification (RFID technology for a mobilized surgical process monitoring system. Through the active tag, an application management system used before, during, and after the surgical processes has been proposed. The concept of signal level matrix, SLM, was proposed to accurately identify patients and dynamically track patients’ location. By updating patient’s information real-time, the preprocessing time needed for various tasks and incomplete transfers among departments can be reduced, the medical resources can be effectively used, unnecessary medical disputes can be reduced, and more comprehensive health care environment can be provided. The feasibility and effectiveness of our proposed system are demonstrated with a number of experimental results.

    Full Text Available Abstract A few cases of fire in the operating room are reported in the literature. The factors that may initiate these fires are many and include alcohol based surgical prep solutions, electrosurgical equipment, flammable drapes etc. We are reporting a case of fire in the operating room while operating on a patient with burst fracture C6 vertebra with quadriplegia. The cause of the fire was due to incomplete drying of the covering drapes with an alcohol based surgical prep solution. This paper discusses potential preventive measures to minimize the incidence of fire in the operating room.

    Nowadays almost all operating rooms are equipped with air conditioning (AC units). Their main purpose is climatization, like ventilation, moisturizing, cooling and also the warming of the room in large buildings. In operating rooms they have an additional function in the prevention of infections, especially the avoidance of postoperative wound infections. This is achieved by special filtration systems and by the creation of specific air currents. Since hypothermia is known to be an unambiguous factor for the development of postoperative wound infections, patients are often actively warmed intraoperatively using warm air blankets (forced-air warming units). In such cases it is frequently discussed whether such warm air blankets affect the performance of AC units by changing the air currents or whether, in contrast, have exactly the opposite effect. However, it has been demonstrated in numerous studies that warm air blankets do not have any relevant effect on the functioning of AC units. Also there are no indications that their use increases the rate of postoperative wound infections. By preventing the patient from experiencing hypothermia, the rate of postoperative wound infections can even be decreased thereby. © Georg Thieme Verlag Stuttgart · New York.

    The realization of a monolithic all II-VI-based vertical cavity surface emitting laser (VCSEL) for the green spectral region is reported. Optically pumped lasing operation was achieved up to room temperature using a planar VCSEL structure. Taking advantage of distributed Bragg-reflectors based on MgS/Zn(Cd)Se superlattices as the low-refractive index material and ZnS0.06Se0.94 layers as the high-index material with a refractive index contrast of n = 0.6, a quality factor exceeding Q = 2000 is reached by using only 18 Bragg periods for the bottom DBR and 15 Bragg periods for the top DBR. The threshold power density is 0.32 MW/cm2 at a temperature of 10 K (emission wavelength 498.5 nm) and 1.9 MW/cm2 at room temperature (emission wavelength 502.3 nm).

    2014-08-01

    Full Text Available Introduction: The morbidity and mortality rates of tracheotomy are higher in the pediatric population because the incision is small and the trachea is more prone to surgical trauma. Tracheotomy procedure is mostly performed in operating room in most institutions. The aim of the study is to compare the outcomes of tracheotomy procedures between intensive care unit (ICU and operating room (OR in terms of pitfalls, complications and family preferences. Materials and Methods: In between June 2012 and July 2013, at a single institution, 39 patients were prospectively analyzed for age, gender, primary pathology, tracheotomy indications, location of operation, the duration of family consent, perioperative complications and presence of decanulation. Results: Male/female ratio was 20/19. Mean age was 49.9±52.5 (4-204 months. Tracheotomy procedure was performed in OR in 19 patients (45% and in ICU in 20 (54.5% patients. There was no statistically significant difference between groups in terms of complications (OR-48.7%, ICU-51.3%. The time of informed consent was significantly shorter in ICU patients. Conclusions: There is no significant difference in terms of safety for tracheotomy procedure in ICU or OR. Parents give approval to a bedside invasive procedure faster. The words ‘Surgery’ and ‘Operating room’ can easily confuse the parents, extend the duration for endolaryngeal intubation, and increase the cost and labour loss.

    Research has demonstrated that practice in surgical simulators leads to improved performance in that simulator. Our hypothesis is that skills acquired in simulators are transferable to the operating room. Twenty-three laparoscopically naïve surgical interns performed two standardized tasks in a simulator: pegboard transfer and intracorporeal knot tying. Performance was measured using a validated scoring system. On the same day as this initial assessment, subjects were videotaped performing two tasks in a live porcine model: running the small bowel and intracorporeal knot tying. Performance in the porcine model was measured using a modified version of a validated skills assessment tool by two blinded experts. Following a 6-wk proficiency-based dry lab laparoscopic training course, task performance was re-evaluated. No interval live operative laparoscopic experience occurred between the first and second assessment. After training, mean pegboard transfer scores increased from 118.7 to 181.8 (theoretical maximum = 300; P operative model. We believe that this is evidence that laparoscopic skills developed in a dry laboratory setting are transferable to the operating room.

    Work in health care units is associated with considerable physical strain and many musculoskeletal complaints. Most investigations have concentrated on the work of general hospital nurses; little is known about the physical stress load on other health care workers. We therefore carried out an ergonomic study amongst operating room staff in order to (i) determine the work (posture) stress load on this particular group of health care workers and the effect of static posture on this stress, (ii) identify activities involving poor work postures, and (iii) determine differences between specialties in regard to work posture stress load. The work postures and related work activities of four different groups of staff in operating rooms (surgeons, assistant anaesthesists, instrumentation nurses and circulating nurses) were recorded and evaluated using the specified Ovako Working posture Analysing System (OWAS). Observation during the course of 18 daily surgical programmes (total number of observations: 3714) in the specialties general surgery and ear-nose-throat (ENT) surgery revealed that the work-load according to OWAS for circulating nurses and assistant anaesthesists was not harmful. Some work postures seen among instrumentation nurses and surgeons, however, need improvement. The work posture stress load in these groups is mainly due to the high prevalence of static work postures during the activities "surgery" (surgeons) and "assisting surgery" (instrumentation nurses). Significant differences in ergonomic stress load were observed between general surgeons and ENT surgeons. This survey in operating theatres relates work postures to basic activities and can be used as a starting point from which to improve work conditions in order to reduce or eliminate physical complaints among operating room staff.

    Verbal communication in the operating room during surgical procedures affects team performance, reflects individual skills, and is related to the complexity of the operation process. During the procedural training of surgeons (residents), feedback and guidance is given through verbal communication. A classification method based on structural analysis of the contents was developed to analyze verbal communication. This study aimed to evaluate whether a classification method for the contents of verbal communication in the operating room could provide insight into the teaching processes. Eight laparoscopic cholecystectomies were videotaped. Two entire cholecystectomies and the dissection phase of six additional procedures were analyzed by categorization of the communication in terms of type (4 categories: commanding, explaining, questioning, and miscellaneous) and content (9 categories: operation method, location, direction, instrument handling, visualization, anatomy and pathology, general, private, undefinable). The operation was divided into six phases: start, dissection, clipping, separating, control, closing. Classification of the communication during two entire procedures showed that each phase of the operation was dominated by different kinds of communication. A high percentage of explaining anatomy and pathology was found throughout the whole procedure except for the control and closing phases. In the dissection phases, 60% of verbal communication concerned explaining. These explaining communication events were divided as follows: 27% operation method, 19% anatomy and pathology, 25% location (positioning of the instrument-tissue interaction), 15% direction (direction of tissue manipulation), 11% instrument handling, and 3% other nonclassified instructions. The proposed classification method is feasible for analyzing verbal communication during surgical procedures. Communication content objectively reflects the interaction between surgeon and resident.

    The objective of the study was to assess the risk factors associated with return to the operating room in bariatric surgery patients. Using the American College of Surgeons-National Surgical Quality Improvement Project's participant-use file, patients who underwent laparoscopic gastric bypass (LRYGB) and adjustable gastric band (LAGB) procedures for morbid obesity were identified. Several pre-, peri-, and postoperative variables, including 30 day morbidity and mortality, were collected. The study population was divided into two groups: patients returning to the operating room (group 1), and patients not returning to the operating room (group 2). Variables analyzed included postoperative complications, overall morbidity, and mortality. Relationships between preoperative and perioperative factors leading to the return to the operating room also were analyzed. Of 28,241 (LRYGB = 18,671, LAGB = 9,570) patients included in the study, 644 (2.3 %) patients returned to the operating room. Of the study population, 30 day mortality rate was 0.13 % (37/28,241) and morbidity was 4.1 % (1,155/28,241). Patients returning to the operating room had a higher mortality [14/644 (2.2 %) vs. 23/27,597 (0.01 %); P return to the operating room. Postoperative complications (superficial wound infection, deep surgical site infection, organ space infection, pneumonia, pulmonary embolism, renal insufficiency, renal failure, septic shock, and length of stay) were significantly higher for patients who required reoperation. On multivariate logistic regression analysis, the bypass operation, bleeding disorder, patients on dialysis, preoperative hematocrit, preoperative low albumin, and length of operation were associated with increased risk of return to the operating room. In the bariatric population, return to the operating room is associated with significantly higher morbidity and mortality. Patients who are on dialysis, have a low preoperative serum albumin, and a history of bleeding disorders

    This paper studied a C-arm's exposure condition and measured scatter rays by thickness and distance. This study reached the following conclusion. Approximately exposure dose for a patient using fluoroscopy is as follows: Mostly, an operating room was not shielding by lead and operator put on only apron without thyroid and facial part protection. 0.5 mmPb equivalent's apron shielded about 99% of scattered rays at 60 cm from x-ray tube. Scattered rays are depended on distance and thickness so operators are should be careful when using fluoroscopy by C-arm and if possible use high frequency equipment that has a large output.

  5. Forced-air warming: a source of airborne contamination in the operating room?

    2009-12-01

    Full Text Available Forced-air-warming (FAW is an effective and widely used means for maintaining surgical normothermia, but FAW also has the potential to generate and mobilize airborne contamination in the operating room. We measured the emission of viable and non-viable forms of airborne contamination from an arbitrary selection of FAW blowers (n=25 in the operating room. A laser particle counter measured particulate concentrations of the air near the intake filter and in the distal hose airstream. Filtration efficiency was calculated as the reduction in particulate concentration in the distal hose airstream relative to that of the intake. Microbial colonization of the FAW blower’s internal hose surfaces was assessed by culturing the microorganisms recovered through swabbing (n=17 and rinsing (n=9 techniques. Particle counting revealed that 24% of FAW blowers were emitting significant levels of internally generated airborne contamination in the 0.5 to 5.0 mm size range, evidenced by a steep decrease in FAW blower filtration efficiency for particles 0.5 to 5.0 mm in size. The particle size-range-specific reduction in efficiency could not be explained by the filtration properties of the intake filter. Instead, the reduction was found to be caused by size-range-specific particle generation within the FAW blowers. Microorganisms were detected on the internal air path surfaces of 94% of FAW blowers. The design of FAW blowers was found to be questionable for preventing the build-up of internal contamination and the emission of airborne contamination into the operating room. Although we did not evaluate the link between FAW and surgical site infection rates, a significant percentage of FAW blowers with positive microbial cultures were emitting internally generated airborne contamination within the size range of free floating bacteria and fungi (<4 mm that could, conceivably, settle onto the surgical site.

    Surgery is one of the key functions in hospitals; it generates significant revenue and admissions to hospitals. In this paper we address the decision of choosing a case-mix for a surgery department. The objective of this study is to generate an optimal case-mix plan of surgery patients with uncertain surgery operations, which includes uncertainty in surgery durations, length of stay, surgery demand and the availability of nurses. In order to obtain an optimal case-mix plan, a stochastic optimization model is proposed and the sample average approximation method is applied. The proposed model is used to determine the number of surgery cases to be weekly served, the amount of operating rooms' time dedicated to each specialty and the number of ward beds dedicated to each specialty. The optimal case-mix selection criterion is based upon a weighted score taking into account both the waiting list and the historical demand of each patient category. The score aims to maximizing the service level of the operating rooms by increasing the total number of surgery cases that could be served. A computational experiment is presented to demonstrate the performance of the proposed method. The results show that the stochastic model solution outperforms the expected value problem solution. Additional analysis is conducted to study the effect of varying the number of ORs and nurses capacity on the overall ORs' performance.

    To identify sucessful teaching techniques in the operating room environment through examining the teaching of the midurethral sling (MUS) surgery. The authors distributed questionnaires with open-ended questions about teaching and learning MUS to 5 urogynecology attendings and 16 obstetrics-gynecology residents in spring 2010. In an effort to identify qualities of an effective sling teacher, the authors used grounded theory to determine common themes and to code participant responses for examples. Of 21 potential respondents, 14 (67%) returned questionnaires. The authors analyzed these and identified seven commonalities among effective sling teachers: they (1) emphasize anatomical landmarks (as determined by 64 total comments); (2) use perceptual-motor teaching (PMT; 38 comments); (3) encourage repetition (28); (4) promote early independence (34); (5) demonstrate confident competence (23); (6) maintain a calm demeanor in the operating room (20); and (7) exhibit a willingness to accept responsibility for mistakes and consequences (9). The second-most common attribute, using PMT, requires the teaching attending to emphasize the motor and tactile aspects of operating and involves incorporating not only what learners see but also what they feel. The authors report seven qualities or techniques fundamental to good teaching practice in a high-stress, high-technology surgical environment, and they have identified the use of PMT, which to their knowledge has not been previously described. Teachers and learners in this study characterized PMT, which is likely generalizable to surgical procedures other than the MUS, as important. Future research should focus on exploring this technique in other surgeries.

    Today it is possible to automate almost any function in a human-machine system. Therefore it is important to find a balance between automation level and the prerequisites for the operator to maintain safe operation. Different human factors evaluation methods can be used to find differences between automatic and manual operations that have an effect on operator performance; e.g. Predictive Human Error Analysis (PHEA), NASA Task Load Index (NASA-TLX), Halden Questionnaire, and Human Error Assessment and Reduction Technique (HEART). Results from an empirical study concerning automation levels, made at Ringhals power plant, showed that factors as time pressure and criticality of the work situation influenced the operator's performance and mental workload more than differences in level of automation. The results indicate that the operator's attention strategies differ between the manual and automatic sequences. Independently of level of automation, it is essential that the operator retains control and situational understanding. When performing a manual task, the operator is 'closer' to the process and in control with sufficient situational understanding. When the level of automation increases, the demands on information presentation increase to ensure safe plant operation. The need for control can be met by introducing 'control gates' where the operator has to accept that the automatic procedures are continuing as expected. Situational understanding can be established by clear information about process status and by continuous feedback. A conclusion of the study was that a collaborative control room environment is important. Rather than allocating functions to either the operator or the system, a complementary strategy should be used. Key parameters to consider when planning the work in the control room are time constraints and task criticality and how they affect the performance of the joint cognitive system.However, the examined working

    Full Text Available ABSTRACT Purpose: We assessed and evaluated attitudes and knowledge regarding ionizing radiation of urology surgery room staff. Materials and Methods: A questionnaire was sent by e-mail to urology surgery room personnel in Turkey, between June and August 2013. The questionnaire included demographic questions and questions regarding radiation exposure and protection. Results: In total, 127 questionnaires were answered. Of them, 62 (48.8% were nurses, 51 (40.2% were other personnel, and 14 (11% were radiological technicians. In total, 113 (89% participants had some knowledge of radiation, but only 56 (44.1% had received specific education or training regarding the harmful effects of radiation. In total, 92 (72.4% participants indicated that they used a lead apron and a thyroid shield. In the subgroup that had received education about the harmful effects of radiation, the use ratio for all protective procedures was 21.4% (n=12; this ratio was only 2.8% (n=2 for those with no specific training; the difference was statistically significant (p=0.004. Regarding dosimeters, the use rates were 100% for radiology technicians, 46.8% for nurses, and 31.4% for other hospital personnel; these differences were statistically significant (p<0.001. No significant relationship between working period in the surgery room, number of daily fluoroscopy procedures, education, task, and use of radiation protection measures was found. Conclusions: It is clear that operating room-allied health personnel exposed to radiation do not have sufficient knowledge of ionizing radiation and they do not take sufficient protective measures.

    Digitalized MMI(Man-Machine Interface) including Digital Main Control Room(MCR) and digital I and C system was being applied for SKN 3 and 4 Nuclear Power Plant(NPP) and subsequent APR1400 NPP type. But, operators can not easily find instrument for alarm immediately. Therefore, Alarm system is required to easily find instrument for Alarm. For this implementation, we will plan system design considering design feature without affecting network load and CPU load. We have developed Alarm system link drawing for digital MCR. Operators of the digitalized MCR navigates from their consoles to the drawings related to the plant alarms and their instruments or the operation status. Such method gives cognitive load to the operators having to travel to different locations in finding the related information. Screen Sharing System, which is the fundamental technique for Drawing Interconnection Alarm System is close to completion, and it should be functionally tested and verified by the human factor engineering. For the actual application to the operating plants, the drawings to be interconnected to the alarms and the opinions from the operators/maintenance departments for designating alarm number should be surveyed, Also, another function that allows the access to the alarm related drawings not only from the MCR but also from the other offices.

    To prevent surgical site infection (SSI), the airborne microbial concentration in operating theaters must be reduced. The air quality in operating theaters and nearby areas is also important to healthcare workers. Therefore, this study assessed air quality in the post-operative recovery room, locations surrounding the operating theater area, and operating theaters in a medical center. Temperature, relative humidity (RH), and carbon dioxide (CO2), suspended particulate matter (PM), and bacterial concentrations were monitored weekly over one year. Measurement results reveal clear differences in air quality in different operating theater areas. The post-operative recovery room had significantly higher CO2 and bacterial concentrations than other locations. Bacillus spp., Micrococcus spp., and Staphylococcus spp. bacteria often existed in the operating theater area. Furthermore, Acinetobacter spp. was the main pathogen in the post-operative recovery room (18%) and traumatic surgery room (8%). The mixed effect models reveal a strong correlation between number of people in a space and high CO2 concentration after adjusting for sampling locations. In conclusion, air quality in the post-operative recovery room and operating theaters warrants attention, and merits long-term surveillance to protect both surgical patients and healthcare workers.

    We propose an easy-to-construct digital video editing system ideal to produce video documentation and still images. A digital video editing system applicable to many video sources in the operating room is described in detail. The proposed system has proved easy to use and permits one to obtain videography quickly and easily. Mixing different streams of video input from all the devices in use in the operating room, the application of filters and effects produces a final, professional end-product. Recording on a DVD provides an inexpensive, portable and easy-to-use medium to store or re-edit or tape at a later time. From stored videography it is easy to extract high-quality, still images useful for teaching, presentations and publications. In conclusion digital videography and still photography can easily be recorded by the proposed system, producing high-quality video recording. The use of firewire ports provides good compatibility with next-generation hardware and software. The high standard of quality makes the proposed system one of the lowest priced products available today.

    Although surgical smoke contains potentially hazardous substances, such as cellular material, blood fragments, microorganisms, toxic gases and vapors, many operating rooms (ORs) do not provide protection from exposure to it. This article reviews the hazards of surgical smoke and the means of protecting OR personnel. Our objectives are to promote surgeons' acceptance to adopt measures to minimize the hazards. Depending on its components, surgical smoke can increase the risk of acute and chronic pulmonary conditions, cause acute headaches; irritation and soreness of the eyes, nose and throat; dermatitis and colic. Transmission of infectious disease may occur if bacterial or viral fragments present in the smoke are inhaled. The presence of carcinogens in surgical smoke and their mutagenic effects are also of concern. This review summarizes previously published reports and data regarding the toxic components of surgical smoke, the possible adverse effects on the health of operating room personnel and measures that can be used to minimize exposure to prevent respiratory problems. To reduce the hazards, surgical smoke should be removed by an evacuation system. Surgeons should assess the potential dangers of surgical smoke and encourage the use of evacuation devices to minimize potential health hazards to both themselves and other OR personnel.

    We ran a Multidisciplinary Operating Room Simulation (MORSim) course for 20 complete general surgical teams from two large metropolitan hospitals. Our goal was to improve teamwork and communication in the operating room (OR). We hypothesised that scores for teamwork and communication in the OR would improve back in the workplace following MORSim. We used an extended Behavioural Marker Risk Index (BMRI) to measure teamwork and communication, because a relationship has previously been documented between BMRI scores and surgical patient outcomes. Trained observers scored general surgical teams in the OR at the two study hospitals before and after MORSim, using the BMRI. Analysis of BMRI scores for the 224 general surgical cases before and 213 cases after MORSim showed BMRI scores improved by more than 20% (0.41 v 0.32, pteamwork score would translate into a clinically important reduction in complications and mortality in surgical patients. We demonstrated an improvement in scores for teamwork and communication in general surgical ORs following our intervention. These results support the use of simulation-based multidisciplinary team training for OR staff to promote better teamwork and communication, and potentially improve outcomes for general surgical patients.

    Lean Six Sigma (LSS) is a process improvement methodology that utilizes a collaborative team effort to improve performance by systematically identifying root causes of problems. Our objective was to determine whether application of LSS could improve efficiency when applied simultaneously to all services of an academic children's hospital. In our tertiary academic medical center, a multidisciplinary committee was formed, and the entire perioperative process was mapped, using fishbone diagrams, Pareto analysis, and other process improvement tools. Results for Children's Hospital scheduled main operating room (OR) cases were analyzed, where the surgical attending followed themselves. Six hundred twelve cases were included in the seven Children's Hospital operating rooms (OR) over a 6-month period. Turnover Time (interval between patient OR departure and arrival of the subsequent patient) decreased from a median 41min in the baseline period to 32min in the intervention period (p<0.0001). Turnaround Time (interval between surgical dressing application and subsequent surgical incision) decreased from a median 81.5min in the baseline period to 71min in the intervention period (p<0.0001). These results demonstrate that a coordinated multidisciplinary process improvement redesign can significantly improve efficiency in an academic Children's Hospital without preselecting specific services, removing surgical residents, or incorporating new personnel or technology.

    We report room-temperature operation of 1 × 1 cm2 infrared photoconductive photodetectors based on silicon supersaturated with titanium. We have fabricated these Si-based infrared photodetectors devices by means of ion implantation followed by a pulsed laser melting process. A high sub-band gap responsivity of 34 mV W-1 has been obtained operating at the useful telecommunication applications wavelength of 1.55 μm (0.8 eV). The sub-band gap responsivity shows a cut-off frequency as high as 1.9 kHz. These Si-based devices exhibit a non-previous reported specific detectivity of 1.7 × 104 cm Hz1/2 W-1 at 660 Hz, under a 1.55 μm wavelength light. This work shows the potential of Ti supersaturated Si as a fully CMOS-compatible material for the infrared photodetection technology.

    The algorithm to schedule add-on elective cases that maximizes operating room (OR) suite utilization is unknown. The goal of this study was to use computer simulation to evaluate 10 scheduling algorithms described in the management sciences literature to determine their relative performance at scheduling as many hours of add-on elective cases as possible into open OR time. From a surgical services information system for two separate surgical suites, the authors collected these data: (1) hours of open OR time available for add-on cases in each OR each day and (2) duration of each add-on case. These empirical data were used in computer simulations of case scheduling to compare algorithms appropriate for "variable-sized bin packing with bounded space." "Variable size" refers to differing amounts of open time in each "bin," or OR. The end point of the simulations was OR utilization (time an OR was used divided by the time the OR was available). Each day there were 0.24 +/- 0.11 and 0.28 +/- 0.23 simulated cases (mean +/- SD) scheduled to each OR in each of the two surgical suites. The algorithm that maximized OR utilization, Best Fit Descending with fuzzy constraints, achieved OR utilizations 4% larger than the algorithm with poorest performance. We identified the algorithm for scheduling add-on elective cases that maximizes OR utilization for surgical suites that usually have zero or one add-on elective case in each OR. The ease of implementation of the algorithm, either manually or in an OR information system, needs to be studied.

    Poor inter-professional collaboration might negatively influence adequate planning of operative procedures. Interventions capable of improving inter-professional collaboration will positively impact professional practice and health care outcomes. Radboud University Medical Center (UMC) redesigned their operating room (OR) scheduling method by implementing cross-functional teams (CFTs). In this center, positive effects of CFTs were already demonstrated in a mono-center study. This study aims to confirm these effects by comparing the Radboud data with data from 6 other similar centers using a nationwide OR benchmark collaborative. The effect of CFTs was measured by the performance indicator "raw utilization." The Kruskal-Wallis one-way ANOVA was applied to compare OR performance among all 7 centers. The Wilcoxon-Mann-Whitney test was used to determine differences in OR performance between Radboud UMC and the control group. Operating room performance differed significantly among all 7 centers (p<0.0005). Radboud UMC demonstrated the highest median raw utilization of 94% vs 85% in the control group (p<0.0005). Box-and-whisker plots validated the reduced variation during the years, indicating an organizational learning effect. Therefore, not only a better performance than the control group, but also a gradual improvement of this performance during the years. This study shows that multidisciplinary collaboration in CFTs during the perioperative phase has a positive influence on OR scheduling and use of OR time. Other national databases considering mortality rates also support the idea that introducing CFTs is not only an important condition for improving OR performance, but also for improving quality of care.

    Fellowship-trained orthopaedic traumatologists are presumably taught skill sets leading to "best practice" outcomes and more efficient use of hospital resources. This should result in more favorable economic opportunities when compared with general orthopaedic surgeons (GOSs) providing similar clinical services. The purpose of our study was to compare the operating room utilization and financial data of traumatologists versus GOSs at a level II trauma center. Retrospective review. Level II community-based trauma hospital. Patients who presented to the emergency room at our institution with fractures and orthopaedic conditions requiring surgical intervention from January 1, 2010, to December 31, 2011. Operative fracture fixation by members of our orthopaedic trauma panel, including fellowship and nontrauma fellowship-trained orthopaedic surgeons. Our institutional database was queried to determine operative times, surgical supply and implant costs, and surgery labor expenses. Patients were stratified according to those treated by our trauma panel's 3 traumatologists and those treated by the 15 GOSs on our trauma panel. These 2 groups were then compared using standard statistical methods. A total of 6449 orthopedic cases were identified and 2076 of these involved fracture care. One thousand one hundred ninety-nine patients were treated by traumatologists and 877 by GOSs. There was no statistical difference detected in American Society of Anesthesiologists score between trauma and nontrauma groups. Overall, the traumatologist group demonstrated significantly decreased procedure times when compared with the GOS group (55.6 vs. 75.8 minutes, P , 0.0001). In 16 of 18 most common procedure types, traumatologists were more efficient. This led to significantly decreased surgical labor costs ($381.4 vs. $484.8; P Economic Level IV.

    Modern operating room (OR) suites are mostly digitally connected but until now the primary focus was on the presentation, transfer and distribution of images. Device information and processes within the operating theaters are barely considered. Cognitive assistance systems have triggered a fundamental rethinking in the automotive industry as well as in logistics. In principle, tasks in the OR, some of which are highly repetitive, also have great potential to be supported by automated cognitive assistance via a self-thinking system. This includes the coordination of the entire workflow in the perioperative process in both the operating theater and the whole hospital. With corresponding data from hospital information systems, medical devices and appropriate models of the surgical process, intelligent systems could optimize the workflow in the operating theater in the near future and support the surgeon. Preliminary results on the use of device information and automatically controlled OR suites are already available. Such systems include, for example the guidance of laparoscopic camera systems. Nevertheless, cognitive assistance systems that make use of knowledge about patients, processes and other pieces of information to improve surgical treatment are not yet available in the clinical routine but are urgently needed in order to automatically assist the surgeon in situation-related activities and thus substantially improve patient care.

    We developed a small InSb mid-infrared (2-7 µm wavelength range) photon detector that operates at room temperature. The photodiode was made from (hetero epitaxial) InSb layers that were grown on a semi-insulating GaAs substrate by molecular beam epitaxy. To suppress the effects of the diffusion current of the p-i-n photodiode, we used an AlInSb barrier layer that raises the resistance of the photodiode. We also optimized the device's doping concentration and the infrared incidence window structure. These optimization steps realized high photoelectric current output in a room-temperature environment. We also increased the signal-to-noise ratio of the detector by connecting multiple photodiodes in series. The size of this detector is 1.9×2.7×0.4 mm3 and the detectivity is 2.8×108 cm Hz1/2/W at 300 K. This is a practical IR detector that can be used in general signal amplification ICs.

    Observations of surgical teams in the operating room (OR) and interviews with surgeons, circulating registered nurses (RNs), anaesthesiologists and surgical technicians reveal the importance of leadership, team member competencies and an enacted environment that encourages feelings of competence and cooperation. Surgical teams are more loosely coupled than intact and bounded. Team members tend to rely on expected role behaviours to bridge lack of familiarity. While members of the surgical team identified technical competence and preparation as critical factors affecting team performance, they had differing views over the role behaviours of other members of the surgical team that lead to surgical team performance. Observations revealed that the work climate in the OR can shape interpersonal relations and begins to be established when the room is being set up for the surgical case, and evolves as the surgical procedure progresses. The leadership and supervisory competencies of the circulating RNs establish the initial work environment. Both influenced the degree of cooperation and support that was observed, which had an effect on the interactions and relationships between other members of the surgical team. As the surgery unfolds, the surgeon's behaviours and interpersonal relations modify this environment and ultimately influence the degree of team work, team satisfaction and team performance.

    Two kinds of continuous-wave GaN-based ultraviolet laser diodes (LDs) operated at room temperature and with different emission wavelengths are demonstrated. The LDs epitaxial layers are grown on GaN substrate by metalorganic chemical vapor deposition, with a 10 × 600 μm2 ridge waveguide structure. The electrical and optical characteristics of the ultraviolet LDs are investigated under direct-current injection at room temperature. The stimulated emission peak wavelength of first LD is 392.9 nm, the threshold current density and voltage is 1.5 kA/cm2 and 5.0 V, respectively. The output light power is 80 mW under the 4.0 kA/cm2 injection current density.

    2012-01-01

    Full Text Available This review paper discusses the ergonomic challenges associated with laparoscopy in the operating room (OR and summarizes the practical ergonomic solutions. The literature search was conducted in the fields of laparoscopy and applied ergonomics. Findings indicated that laparoscopic OR staff (surgeons, perioperative nurses and technicians commonly experienced physical and mental ergonomic risks while working in prolonged static and awkward body positions. This study highlighted the need for more ergonomic interventions in OR environment in order to improve the efficiency of laparoscopy. Ergonomic solutions included utilizing adjustable equipment, placing computer peripherals in optimal locations, providing ergonomic instruments, and improving communication. Understanding the job- or task-related ergonomic risks and hazards could help identify intervention requirements to meet the challenges associated with increased dependency on advanced high technology in the OR.

    Kindsmüller, Martin Christof; Haar, Maral; Schulz, Hannes; Herczeg, Michael

    Today’s physicians and nurses working in operating rooms and intensive care units have to deal with an ever increasing amount of data. More and more medical devices are delivering information, which has to be perceived and interpreted in regard to patient status and the necessity to adjust therapy. The combination of high information load and insufficient usability creates a severe challenge for the health personnel with respect to proper monitoring of these devices respective to acknowledging alarms and timely reaction to critical incidents. Smart Applications are a new kind of decision support systems that incorporate medical expertise in order to help health personnel in regard to diagnosis and therapy. By means of a User Centered Design process of two Smart Applications (anaesthesia monitor display, diagnosis display), we illustrate which approach should be followed and which processes and methods have been successfully applied in fostering the design of usable medical devices.

    We developed an augmented reality system targeting image guidance for surgical procedures. The surgeon wears a video- see-through head mounted display that provides him with a stereo video view of the patient. The live video images are augmented with graphical representations of anatomical structures that are segmented from medical image data. The surgeon can see, e.g., a tumor in its actual location inside the patient. This in-situ visualization, where the computer maps the image information onto the patient, promises the most direct, intuitive guidance for surgical procedures. In this paper, we describe technical details of the system and its installation in UCLA's iMRI operating room. We added instrument tracking to the capabilities of our system to prepare it for minimally invasive procedures. We discuss several pre-clinical phantom experiments that support the potential clinical usefulness of augmented reality guidance.

    2009-03-01

    The number of operating rooms and intensive care departments equipped with a clinical information system (CIS) is rapidly expanding. Amongst the putative advantages of such an installation, reduction in workload for the clinician is one of the most appealing. The scarce studies looking at workload variations associated with the implementation of a CIS, only focus on direct workload discarding indirect changes in workload. Descriptions of the various methods to quantify workload are provided. The hypothesis that a third generation CIS can reduce documentation time for ICU nurses and increase time they spend on patient care, is supported by recent literature. Though it seems obvious to extrapolate these advantages of a CIS to the anesthesiology department or physicians in the intensive care, studies examining this assumption are scarce.

    Investigate risk factors for unplanned return to the operating room after resident-performed cataract surgery. Retrospective case-control study. Institutional. Study population: All patients with reoperation within 90 days of resident-performed phacoemulsification were matched to four control eyes which had surgery within 30 days of the reoperation at the same institution. Billing codes were used to identify all patients who underwent resident-performed intended phacoemulsification with intraocular lens placement from January 2005 to December 2010. Investigated risk factors for reoperation included cataract characteristics and preexisting ocular co-morbidities, including diabetic retinopathy, retinal detachment history, glaucoma, corneal pathology, and uveitis. Additional preoperative risk factors studied included resident training year, history of tamsulosin use, phacodonesis, pupillary dilation, presence of pseudoexfoliation, myopia, history of trauma, visual acuity, and monocular status. Intraoperative variables were the use of iris expansion devices, use of capsular stain, attending type, incision type, use of sutures, vitreous loss, anesthesia type, and phacoemulsification technique. There were 67 returns to the operating room (i.e., cases) over five years that were assigned to 268 control eyes. In preoperative multivariate analysis, phacoemulsification done by a first- or second-year resident (OR 3.2, 95% CI: 1.7-6.0, p risk of reoperation. In postoperative multivariate analysis, only the use of the divide-and-conquer technique (OR 4.0, 95% CI:1.7-9.2, p = 0.001) was associated with an increased risk of reoperation. Phacoemulsification done by a junior resident or using the divide-and-conquer technique had the highest risk of reoperation.

    The purpose of this study is to quantify the impact of the weight of radiation protection lead aprons on the discomfort and the fatigue of the medical staff within an operating room of interventional gastroenterology. To quantify this fatigue, we analyzed variations of the physiological parameters, including heart rate, blood pressure, and cutaneous temperature; we compared two situations: the first within the classic endoscopy department (without apron) and the second within the operating room with apron. A follow-up study with lighter lead aprons was also conducted. We used infrared thermography as the principal method of analysis in our study. This technique permits us to obtain data, without body contact, of the spatial and temporal orientation of temperatures on subject skin. This method proves to be beneficial in the evaluation of the posture of users. The symmetry of the temperature evolution among the different body zones can contribute to the body balance analysis. Our results of the cutaneous temperatures obtained by infrared camera show significant differences in the muscular activity. All the muscular groups studied were revealed significant temperature increases. The temperature curve T2-T1 reveals the actual influence of carrying heavy apron loads. Regardless of the muscular group, this temperature increase varies on the range between 0.55°C and 0.95°C. The muscular groups most recruited are the trapezoids and pectorals. The muscles least recruited are those of the lower limbs. The study shows the impact of load bearing on the body mechanics of medical staff during work. It will be beneficial to develop this study to predict changes in skin temperature because of the various types of aprons and to determine the possible correlation between the thermal distribution and users' sense of comfort.

  17. Anesthetic drug wastage in the operation room: A cause for concern

    Directory of Open Access Journals (Sweden)

    Kapil Chaudhary

    2012-01-01

    Full Text Available Context: The cost of anesthetic technique has three main components, i.e., disposable supplies, equipments, and anesthetic drugs. Drug budgets are an easily identifiable area for short-term savings. Aim: To assess and estimate the amount of anesthetic drug wastage in the general surgical operation room. Also, to analyze the financial implications to the hospital due to drug wastage and suggest appropriate steps to prevent or minimize this wastage. Settings and Design: A prospective observational study conducted in the general surgical operation room of a tertiary care hospital. Materials and Methods: Drug wastage was considered as the amount of drug left unutilized in the syringes/vials after completion of a case and any ampoule or vial broken while loading. An estimation of the cost of wasted drug was made. Results: Maximal wastage was associated with adrenaline and lignocaine (100% and 93.63%, respectively. The drugs which accounted for maximum wastage due to not being used after loading into a syringe were adrenaline (95.24%, succinylcholine (92.63%, lignocaine (92.51%, mephentermine (83.80%, and atropine (81.82%. The cost of wasted drugs for the study duration was 46.57% (Rs. 16,044.01 of the total cost of drugs issued/loaded (Rs. 34,449.44. Of this, the cost of wastage of propofol was maximum being 56.27% (Rs. 9028.16 of the total wastage cost, followed by rocuronium 17.80% (Rs. 2856, vecuronium 5.23% (Rs. 840, and neostigmine 4.12% (Rs. 661.50. Conclusions: Drug wastage and the ensuing financial loss can be significant during the anesthetic management of surgical cases. Propofol, rocuronium, vecuronium, and neostigmine are the drugs which contribute maximally to the total wastage cost. Judicious use of these and other drugs and appropriate prudent measures as suggested can effectively decrease this cost.

    In modern operating rooms, clean and unused medical supplies are routinely discarded and can be effectively recovered and redistributed abroad to alleviate the environmental burden of donor hospitals and to generate substantial health benefits at resource-poor recipient institutions. We established a recovery and donation program to collect clean and unused supplies for healthcare institutions in developing nations. We analyzed items donated over a 3-year period (September 2010-November 2013) by quantity and weight, and estimated the projected value of the program under potential nationwide participation. To capture the health benefits attributable to the donated supplies at recipient institutions, we partnered with two tertiary-care centers in Guayaquil, Ecuador and conducted a pilot study on the utility of the donated supplies at the recipient institutions (October 2013). We determined the disability-adjusted life years (DALY) averted for all patients undergoing procedures involving donated items and estimated the annual attributable DALY as well as the cost per DALY averted both by supply and by procedure. Approximately, 2 million lbs (907,185 kg) per year of medical supplies are recoverable from large non-rural US academic medical centers. Of these supplies, 19 common categories represent a potential for donation worth US $15 million per year, at a cost-utility of US $2.14 per DALY averted. Hospital operating rooms continue to represent a large source of recoverable surgical supplies that have demonstrable health benefits in the recipient communities. Cost-effective recovery and need-based donation programs can significantly alleviate the global burden of surgical diseases.

  19. Influence of the operating room schedule on tardiness from scheduled start times.

    Tardiness from scheduled start times in a surgical suite is a common source of frustration for both operating room personnel and patients. Data from two surgical suites were used to investigate the relative importance of various factors that contribute to tardiness, including average case duration, time of day, prolonged turnovers, whether a surgeon follows himself or another surgeon, the potential for starting cases early, concurrency (e.g., number of residents supervised simultaneously), expected under-utilized or over-utilized time, and case duration bias. Average tardiness per case did not depend on the individual durations of preceding cases or on the relative numbers of long and short cases. In contrast, the total duration of preceding cases was important in determining tardiness. Tardiness per case grew larger as the day progressed because the total duration of preceding cases increased, but began to decline for cases scheduled to commence 6 h after the start of the workday. Tardiness was not affected by prolonged turnovers, differences in average case duration among services, or whether a surgeon followed himself or another surgeon in the same operating room. Tardiness was affected by expected under-utilized or over-utilized time at the end of the workday and by case duration bias. Factors associated with the largest numbers of cases had the biggest influence on tardiness. Greater understanding of these factors aided in the development of several mathematical interventions to reduce tardiness in the two surgical suites. These interventions and their applicability for reducing tardiness are described in a companion article. At two surgical suites, tardiness from scheduled start times did not depend on average case duration or prolonged turnovers. Tardiness did depend on the total duration of preceding cases, expected under-utilized or over-utilized time at the end of the day, and case duration bias.

    To reduce the incidence of surgical fires. Operating room fires represent a potentially life-threatening hazard and are triggered by the electrosurgical unit (ESU) pencil. Carbon dioxide is a fire suppressant and is a routinely used medical gas. We hypothesize that a shroud of protective carbon dioxide covering the tip of the ESU pencil displaces oxygen, thereby preventing fire ignition. Using 3-dimensional modeling techniques, a polymer sleeve was created and attached to an ESU pencil. This sleeve was connected to a carbon dioxide source and directed the gas through multiple precisely angled ports, generating a cone of fire-suppressive carbon dioxide surrounding the active pencil tip. This device was evaluated in a flammability test chamber containing 21%, 50%, and 100% oxygen with sustained ESU activation. The sleeve was tested with and without carbon dioxide (control) until a fuel was ignited or 30 seconds elapsed. Time to ignition was measured by high-speed videography. Fires were ignited with each control trial (15/15 trials). The control group median ± SD ignition time in 21% oxygen was 3.0 ± 2.4 seconds, in 50% oxygen was 0.1 ± 1.8 seconds, and in 100% oxygen was 0.03 ± 0.1 seconds. No fire was observed when the fire safety device was used in all concentrations of oxygen (0/15 trials; P fire ignition was 76% to 100%. A sleeve creating a cone of protective carbon dioxide gas enshrouding the sparks from an ESU pencil effectively prevents fire in a high-flammability model. Clinical application of this device may reduce the incidence of operating room fires.

  1. Operating Room Time Savings with the Use of Splint Packs: A Randomized Controlled Trial

    2016-01-01

    Full Text Available Background: The most expensive variable in the operating room (OR is time. Lean Process Management is being used in the medical field to improve efficiency in the OR. Streamlining individual processes within the OR is crucial to a comprehensive time saving and cost-cutting health care strategy. At our institution, one hour of OR time costs approximately $500, exclusive of supply and personnel costs. Commercially prepared splint packs (SP contain all components necessary for plaster-of-Paris short-leg splint application and have the potential to decrease splint application time and overall costs by making it a more lean process. We conducted a randomized controlled trial comparing OR time savings between SP use and bulk supply (BS splint application. Methods: Fifty consecutive adult operative patients on whom post-operative short-leg splint immobilization was indicated were randomized to either a control group using BS or an experimental group using SP. One orthopaedic surgeon (EMB prepared and applied all of the splints in a standardized fashion. Retrieval time, preparation time, splint application time, and total splinting time for both groups were measured and statistically analyzed. Results: The retrieval time, preparation time and total splinting time were significantly less (p

    Operations research (OR)-based analyses have the potential to improve decision making for many important, real-world health care problems. However, junior scholars often avoid working on practical applications in health because promotion and tenure processes tend to value theoretical studies more highly than applied studies. This paper discusses the author's experiences in using OR to inform and influence decisions in health and provides a blueprint for junior researchers who wish to find success by taking a similar path. This involves selecting good problems to study, forming productive collaborations with domain experts, developing appropriate models, identifying the most salient results from an analysis, and effectively disseminating findings to decision makers. The paper then suggests how journals, funding agencies, and senior academics can encourage such work by taking a broader and more informed view of the potential role and contributions of OR to solving health care problems. Making room in academia for the application of OR in health follows in the tradition begun by the founders of operations research: to work on important real-world problems where operations research can contribute to better decision making.

    The aim of this report is to present a prototype augmented reality (AR) intra-operative brain imaging system. We present our experience of using this new neuronavigation system in neurovascular surgery and discuss the feasibility of this technology for aneurysms, arteriovenous malformations (AVMs), and arteriovenous fistulae (AVFs). We developed an augmented reality system that uses an external camera to capture the live view of the patient on the operating room table and to merge this view with pre-operative volume-rendered vessels. We have extensively tested the system in the laboratory and have used the system in four surgical cases: one aneurysm, two AVMs and one AVF case. The developed AR neuronavigation system allows for precise patient-to-image registration and calibration of the camera, resulting in a well-aligned augmented reality view. Initial results suggest that augmented reality is useful for tailoring craniotomies, localizing vessels of interest, and planning resection corridors. Augmented reality is a promising technology for neurovascular surgery. However, for more complex anomalies such as AVMs and AVFs, better visualization techniques that allow one to distinguish between arteries and veins and determine the absolute depth of a vessel of interest are needed.

    Full Text Available Aim: To identify and quantify factors causing stress in the operating room (OR and evaluate the relationship between these factors and surgeons′ stress level. Methods: This is a prospective observational study from 32 elective surgical procedures conducted in the OR of King Khalid University Hospital, Riyadh, Saudi Arabia. Before each operation, each surgeon was asked of stressors. Two interns observed 16 surgeries each, separately. The interns watched and took notes during the entire surgical procedure. During each operation, the observer recorded anxiety-inducing activities and events that occurred in real time by means of a checklist of 8 potential stressors: technical, patient problems, teamwork problems, time and management issues, distractions and interruptions, equipment problems, personal problems, and teaching. After each operation, surgeons were asked to answer the validated State-Trait Anxiety Inventory questionnaire and self-report on their stress level from the 8 sources using a scale of 1-8 (1: stress free, 8: extremely stressful. The observer also recorded perceived stress levels experienced by the surgeons during the operation. Results: One hundred ten stressors were identified. Technical problems most frequently caused stress (16.4% and personal issues the least often (6.4%. Frequently encountered stressors (teaching and distractions/interruptions caused less stress to the surgeons. Technical factors, teamwork, and equipment problems occurred frequently and were also a major contributor to OR stress. All patients were discharged in good health and within 1 week of surgery. Conclusion: Certain stressful factors do occur among surgeons in the OR and can increase the potential for errors. Further research is required to determine the impact of stress on performance and the outcome of surgery.

    Early trauma deaths have the potential for salvage with immediate surgery. We studied time from injury to death in this group to qualify characteristics and quantify time to the operating room, yielding the greatest opportunity for salvage. The Pennsylvania Trauma Outcomes Study (PTOS) is a comprehensive registry including all Pennsylvania trauma centers. PTOS was queried for adult trauma patients from 1999 to 2010 dying within 4 hours of injury. The distribution of time to death (TD) was examined for subgroups according to mechanism of injury, hypotension (defined as systolic blood pressure ≤ 90 mm Hg), and operation required. The 5th percentile (TD5) and the 50th percentile (TD50) were calculated from the distributions and compared using the Mann-Whitney U-test. The PTOS yielded 6,547 deaths within 4 hours of injury. The overall TD5 and TD50 were 0:23 (hour:minute) and 0:59, respectively. Median penetrating injury times were significantly shorter than blunt injury times (TD5/TD50, 0:19/0:43 vs. 0:29/1:10). Median time was significantly shorter for hypotensive versus normotensive patients (TD5/TD50, 0:22/0:52 vs. 0:43/2:18). Operative subgroups had different TD5/TD50 (abdominal surgery [n = 607], 1:07/2:26; thoracic surgery [n = 756] 0:25/1:25; vascular surgery [n = 156], 0:35/2:15; and cranial surgery [n = 18], 1:20/2:42). Early trauma deaths have the potential for salvage with immediate surgery. We found TD to vary based on mechanism of injury, presence of hypotension, and type of surgery needed. With the use of TD5 and TD50 benchmarks in these subgroups, a trauma system may determine if decreased time to the operating room decreases mortality. Trauma systems can use these data to further improve prehospital and initial hospital phases of care for this subset of early death trauma patients. Epidemiologic study, level III.

    To investigate the effect of coaching on non-technical skills and performance during laparoscopic cholecystectomy in a simulated operating room (OR). Non-technical skills (situation awareness, decision making, teamwork, and leadership) underpin technical ability and are critical to the success of operations and the safety of patients in the OR. The rate of developing assessment tools in this area has outpaced development of workable interventions to improve non-technical skills in surgical training and beyond. A randomized trial was conducted with senior surgical residents (n = 16). Participants were randomized to receive either non-technical skills coaching (intervention) or to self-reflect (control) after each of 5 simulated operations. Coaching was based on the Non-Technical Skills For Surgeons (NOTSS) behavior observation system. Surgeon-coaches trained in this method coached participants in the intervention group for 10 minutes after each simulation. Primary outcome measure was non-technical skills, assessed from video by a surgeon using the NOTSS system. Secondary outcomes were time to call for help during bleeding, operative time, and path length of laparoscopic instruments. Non-technical skills improved in the intervention group from scenario 1 to scenario 5 compared with those in the control group (p = 0.04). The intervention group was faster to call for help when faced with unstoppable bleeding in the final scenario (no. 5; p = 0.03). Coaching improved residents' non-technical skills in the simulated OR compared with those in the control group. Important next steps are to implement non-technical skills coaching in the real OR and assess effect on clinically important process measures and patient outcomes.

    The efficiency of a hospital's operating room (OR) management can affect its overall profitability. However, existing indicators that assess OR management efficiency do not take into account differences in hospital size, manpower and functional characteristics, thereby rendering them unsuitable for multi-institutional comparisons. The aim of this study was to develop indicators of OR management efficiency that would take into account differences in hospital size and manpower, which may then be applied to multi-institutional comparisons. Using administrative data from 224 hospitals in Japan from 2008 to 2010, we performed four multiple linear regression analyses at the hospital level, in which the dependent variables were the number of operations per OR per month, procedural fees per OR per month, total utilization times per OR per month and total fees per OR per month for each of the models. The expected values of these four indicators were produced using multiple regression analysis results, adjusting for differences in hospital size and manpower, which are beyond the control of process owners' management. However, more than half of the variations in three of these four indicators were shown to be explained by differences in hospital size and manpower. Using the ratio of observed to expected values (OE ratio), as well as the difference between the two values (OE difference) allows hospitals to identify weaknesses in efficiency with more validity when compared to unadjusted indicators. The new indicators may support the improvement and sustainment of a high-quality health care system. © 2012 Blackwell Publishing Ltd.

    2014-05-01

    A real case reported to the SENSAR database of incidents is presented. In a patient scheduled for nose fracture repair surgery an unexpected atrial fibrillation was found when monitored in the operating room. The operation was not delayed. After induction of general anaesthesia heart rate suddenly increased and hemodinamic situation was impaired. Cardioversion was required. Two electric countershocks were given but sinus rhythm was not restored. Heart rate was controlled with amiodarone infusion. Optimal defibrillation characteristics are described in these cases. Increased risk of thromboembolism (1-2%) following cardioversion is present even if atrial thrombi are ruled out. The mainstay therapies of are rhythm and rate control and prevention of thromboembolic complications. We describe recommendations on the management of these critical situations with emphasis in learning through the creation of protocols and training practice in simulation.

    Interventions such as mandatory "time-outs" have contributed to intraoperative safety but improvements are still necessary. We present data provided by 3 professions always present in the intraoperative setting that suggest next steps in the quest for improvements. We describe the differences and similarities in operating room (OR) nurses', anesthesia providers', and surgeons' beliefs about team function, case difficulty, nonroutine event (NRE), and error causation using a qualitative design at 3 Veterans' Administration hospitals. Intraoperative errors are costly in lives, suffering, and dollars. A quality improvement tenet states that workers are a rich information source regarding the context within which quality can be improved. Identifying and describing OR providers' beliefs are necessary steps in devising novel approaches to quality improvement. Intraoperative NRE and error prevention opportunities exist within and outside of the OR. There may be "cascade" and "perfect storm conditions" before and during operative procedures that increase the likelihood of NREs. Confirmation of these phenomena could improve prediction and prevention of NREs. Exploration of differences in team definition and team performance ratings by provider type may also identify avenues for improvement.

    To investigate the effect of virtual reality proficiency-based training on actual cataract surgery performance. The secondary purpose of the study was to define which surgeons benefit from virtual reality training. Multicenter masked clinical trial. Eighteen cataract surgeons with different levels of experience. Cataract surgical training on a virtual reality simulator (EyeSi) until a proficiency-based test was passed. Technical performance in the operating room (OR) assessed by 3 independent, masked raters using a previously validated task-specific assessment tool for cataract surgery (Objective Structured Assessment of Cataract Surgical Skill). Three surgeries before and 3 surgeries after the virtual reality training were video-recorded, anonymized, and presented to the raters in random order. Novices (non-independently operating surgeons) and surgeons having performed fewer than 75 independent cataract surgeries showed significant improvements in the OR-32% and 38%, respectively-after virtual reality training (P = 0.008 and P = 0.018). More experienced cataract surgeons did not benefit from simulator training. The reliability of the assessments was high with a generalizability coefficient of 0.92 and 0.86 before and after the virtual reality training, respectively. Clinically relevant cataract surgical skills can be improved by proficiency-based training on a virtual reality simulator. Novices as well as surgeons with an intermediate level of experience showed improvement in OR performance score. Copyright © 2017 American Academy of Ophthalmology. Published by Elsevier Inc.

    We describe the design and implementation of a broad-area (w ≈ 30 μm) quantum-cascade laser operating in a continuous wave mode up to heat-sink temperatures beyond +100 °C. The room-temperature emission wavelength is 4.6 μm. The temperature gradient in the active region of such a wide laser stripe is essentially perpendicular to the epitaxial layers and the resulting steady-state active region temperature offset scales approximately with the square of the number of cascades. With only 10 cascades in the active region, the threshold electrical power density in the current quantum-cascade laser in the continuous-wave mode is as low as Vth × Ith = 3.8 V × 0.9 kA/cm2 = 3.4 kW/cm2 at room temperature for 2 mm-long two-side high-reflectivity coated laser stripe. A 4 mm-long one-side high-reflectivity coated laser stripe delivers in continuous-wave mode above 0.6 W at +20 °C and above 1.3 W at -27 °C (cooled with a single-stage Peltier element). A 2 mm-long two-side high-reflectivity coated laser stripe demonstrates continuous-wave lasing up to at least +102 °C (375 K). The thermal conductance, Gth, ranges between 235 W/K cm2 and 140 W/K cm2 for temperatures between -33 °C and +102 °C. This demonstration opens the route for continuous-wave power scaling of quantum-cascade lasers via broad-area laser ridges.

    Efficiency and quality of documentation are critical in surgical settings because operating rooms are a major source of revenue, and because adverse events may have enormous consequences. Electronic health records (EHRs) have potential to impact surgical volume, quality, and documentation time. Ophthalmology is an ideal domain to examine these issues because procedures are high-throughput and demand efficient documentation. This time-motion study examines nursing documentation during implementation of an EHR operating room management system in an ophthalmology department. Key findings are: (1) EHR nursing documentation time was significantly worse during early implementation, but improved to a level near but slightly worse than paper baseline, (2) Mean documentation time varied significantly among nurses during early implementation, and (3) There was no decrease in operating room turnover time or surgical volume after implementation. These findings have important implications for ambulatory surgery departments planning EHR implementation, and for research in system design.

    Retrospective database review. To evaluate whether microscope use during spine procedures is associated with increased operating room times or increased risk of infection. Operating microscopes are commonly used in spine procedures. It is debated whether the use of an operating microscope increases operating room time or confers increased risk of infection. The American College of Surgeons National Surgical Quality Improvement Program database, which includes data from more than 370 participating hospitals, was used to identify patients undergoing elective spinal procedures with and without the use of an operating microscope for the years 2011 and 2012. Bivariate and multivariate linear regressions were used to test the association between microscope use and operating room times. Bivariate and multivariate logistic regressions were similarly conducted to test the association between microscope use and infection occurrence within 30 days of surgery. A total of 23,670 elective spine procedures were identified, of which 2226 (9.4%) used an operating microscope. The average patient age was 55.1±14.4 years. The average operative time (incision to closure) was 125.7±82.0 minutes.Microscope use was associated with minor increases in preoperative room time (+2.9 min, P=0.013), operative time (+13.2 min, Pmicroscope and nonmicroscope groups for occurrence of any infection, superficial surgical site infection, deep surgical site infection, organ space infection, or sepsis/septic shock, regardless of surgery type. We did not find operating room times or infection risk to be significant deterrents for use of an operating microscope during spine surgery. 3.

    To assess nursing professionals and health care assistants' perceptions, opinions and behaviours on patient safety culture in the operating room of a public hospital of the Spanish National Health Service. To describe strengths and weaknesses or opportunities for improvement according to the Agency for Healthcare Research and Quality criteria, as well as to determine the number of events reported. A descriptive, cross-sectional study was conducted using the Spanish version of the questionnaire Hospital Survey on Patient Safety Culture. The sample consisted of nursing professionals, who agreed to participate voluntarily in this study and met the selection criteria. A descriptive and inferential analysis was performed depending on the nature of the variables and the application conditions of statistical tests. Significance if p < .05. In total, 74 nursing professionals responded (63.2%). No strengths were found in the operating theatre, and improvements are needed concerning staffing (64.0%), and hospital management support for patient safety (52.9%). A total of 52.3% (n = 65) gave patient safety a score from 7 to 8.99 (on a 10 point scale); 79.7% (n = 72) reported no events last year. The total variance explained by the regression model was 0.56 for "Frequency of incident reporting" and 0.26 for "Overall perception of safety". There was a more positive perception of patient safety culture at unit level. Weaknesses have been identified, and they can be used to design specific intervention activities to improve patient safety culture in other nearby operating theatres.

    Photodetectors in the non-visible region of the electromagnetic spectrum are essential for security, defense and space science as well as industrial and scientific applications. The research activities at Fraunhofer IAF cover a broad range in the infrared (IR) regime. Whereas short-wavelength IR (SWIR, <1.7 μm) detectors are realized by InGaAs/InP structures, InAs/GaSb type-II superlattice (T2SL) infrared detectors are developed for the spectral bands from mid- (MWIR, 3-5 μm) to long-wavelength IR (LWIR, 8-12 μm). We report on the extension of the superlattice empirical pseudopotential method (SEPM) to 300 K for the design of LWIR heterostructures for operation near room temperature. Recently, we have also adapted heterostructure concepts to our well established bi-spectral T2SL MWIR detector resulting in a dark current density below 2 × 10-9 A/cm2 for a cut-off wavelength close to 5 μm. Finally, we present first results obtained with a gated viewing system based on our InGaAs/InAlAs/InP avalanche photodiode arrays.

    This study examined the effect of implementing a new preoperative briefing protocol on self- and peer-assessments of individual operating room (OR) teamwork behaviors. From July 2006 to February 2007, OR teamwork performance at a rural community hospital was evaluated before and after training and implementation of the protocol. After each case, every member on the team completed a 360-degree type teamwork behavior evaluation containing both self- and peer-assessments using a six-point Likert type scale (1 = definitely no to 6 = definitely yes). Individual behavior change was measured using the mean scale score of pre and postprotocol assessments. Statistical analysis included t test for both pre/post and self/peer differences. Data were available for one general surgeon and nine OR staff (pre = 20 cases, post = 16 cases). The preprotocol self-assessment mean score was significantly higher than peer-assessment (5.63 vs 5.29, P teamwork behaviors. No difference was observed in postassessment mean scores for self- and peer-assessments. Individuals overestimated their teamwork behaviors before protocol implementation. Using a preoperative protocol seems to improve OR staff teamwork behaviors and self-assessment accuracy. The use of a 360-degree assessment method targeting specific, observable behaviors may be useful in evaluating team-based interventions and enhancing teamwork effectiveness.

    Background. Obesity impacts utilization of healthcare resources. The goal of this study was to measure the relationship between increasing body mass index (BMI) in patients undergoing total hip arthroplasty (THA) with different components of operating room (OR) time. Methods. The Stanford Translational Research Integrated Database Environment (STRIDE) was utilized to identify all ASA PS 2 or 3 patients who underwent primary THA at Stanford Medical Center from February 1, 2008 through January 1, 2013. Patients were divided into five groups based on the BMI weight classification. Regression analysis was used to quantify relationships between BMI and the different components of total OR time. Results. 1,332 patients were included in the study. There were no statistically significant differences in age, gender, height, and ASA PS classification between the BMI groups. Normal-weight patients had a total OR time of 138.9 min compared 167.9 min (P 35 kg/m(2) each incremental BMI unit increase was associated with greater incremental total OR time increases. Conclusion. Morbidly obese patients required significantly more total OR time than normal-weight patients undergoing a THA procedure. This increase in time is relevant when scheduling obese patients for surgery and has an important impact on health resource utilization.

    In recent years, aortic aneurysm treatment with stent graft grafting in the X-ray fluoroscopy is increasing. This is an endovascular therapy, because it is a treatment which includes the risk of radiation damage, having to deal with radiation damage, to know in advance is important. In this study, in order to grasp the trend of exposure stent graft implantation in a hybrid operating room (OR) system, focusing on clinical data (entrance skin dose and fluoroscopy time), was to count the total. In TEVAR and EVAR, fluoroscopy time became 13.40 ± 7.27 minutes, 23.67 ± 11.76 minutes, ESD became 0.87 ± 0.41 mGy, 1.11 ± 0.57 mGy. (fluoroscopy time of EVAR was 2.0 times than TEVAR. DAP of EVAR was 1.2 times than TEVAR.) When using the device, adapted lesions and usage are different. This means that care changes in exposure-related factors. In this study, exposure trends of the stent graft implantation was able to grasp. It can be a helpful way to reduce/optimize the radiation dose in a hybrid OR system.

    The purpose of this study was to examine the impact of state-level general anesthesia (GA) legislation on operating room visits for the treatment of dental caries on preschool-aged children. The North Carolina Ambulatory Surgery Discharge Database was used to observe GA visits for fiscal years (FY) 1997 to 2001. A pretest/post-test design with concurrent comparison groups was used for 2 analyses: (1) all children treated for dental caries were compared to those treated for otitis media; and (2) those whose treatment for dental caries was reimbursed by Medicaid were compared to those whose treatment for dental caries was not reimbursed by Medicaid. In the prelegislation period (FY 1997 and 1998), there were 3,857 GA visits for dental core and 21,038 for otitis media. Postlegislation (FY 2000 and 2001) dental visits increased to 5,511(43%), and otitis media visits increased to 22,279 (6%)-a statistically significant difference (Pdental visits and 2,487 Medicaid dental visits. Non-Medicaid and Medicaid dental visits postlegislation increased to 2,195 (60%) and 3,316 (33%), respectively. This difference was significant (Panesthesia legislation resulted in an increase in access to care for children needing dental care in North Carolina.

    Full Text Available Lessons learned from other high-risk industries could improve patient safety in the operating room (OR. This review describes similarities and differences between high-risk industries and describes current methods and solutions within a system approach to reduce errors in the OR. PubMed and Scopus databases were systematically searched for relevant articles written in the English language published between 2000 and 2011. In total, 25 articles were included, all within the medical domain focusing on the comparison between surgery and aviation. In order to improve safety in the OR, multiple interventions have to be implemented. Additionally, the healthcare organization has to become a ‘learning organization’ and the OR team has to become a team with shared responsibilities and flat hierarchies. Interpersonal and technical skills can be trained by means of simulation and can be supported by implementing team briefings, debriefings and cross-checks. However, further development and research is needed to prove if these solutions are useful, practical, and actually increase safety.

    Operation room (OR) management is not an end in itself. The challenge is more to organize the complex, inhomogeneous and interference-prone machinery of intraoperative service provision according to business objectives. Although business objectives may differ in some details the ultimate consequence is always to assure the quality of medical care along with adhering to the general economic conditions. The narrower the economic framework the smaller the company's tolerance to unprofessional OR management. Consequently, it can be noticed that OR management has become of age. An internal socialization as frontline leader is no longer sufficient for taking over a job profile which, regarding the risks of revenues and costs belongs to the top management of a company. Prior to looking for a future OR manager it is mandatory to develop a profile of qualifications tailored to the company. In the following selection process the important thing is to identify the candidate who fits best to the developed profile. This paper sees itself as an assistance in the development of such a company-specific qualification profile for an OR manager. On the basis of knowledge, skills and characteristics, different manager typologies are developed, facilitating the successful evaluation in a selection process for both the company and the candidate.

    Studies show that using surgical safety checklists (SSCs) reduces complications. Many believe SSCs accomplish this by enhancing teamwork, but evidence is limited. Our study sought to relate teamwork to checklist performance, understand how they relate, and determine conditions that affect this relationship. Using 2 validated tools for observing and coaching operating room teams, we evaluated the association between checklist performance with surgeon buy-in and 4 domains of surgical teamwork: clinical leadership, communication, coordination, and respect. Hospital staff in 10 South Carolina hospitals observed 207 procedures between April 2011 and January 2013. We calculated levels of checklist performance, buy-in, and measures of teamwork, and evaluated their relationship, controlling for patient and case characteristics. Few teams completed most or all SSC items. Teams more often completed items considered procedural "checks" than conversation "prompts." Surgeon buy-in, clinical leadership, communication, a summary measure of teamwork overall, and observers' teamwork ratings positively related to overall checklist completion (multivariable model estimates from 0.04, p teamwork and surgeon buy-in related positively to completing more conversation prompts; none related significantly to procedural checks (estimates from 0.10, p teamwork characterized by shared clinical leadership, open communication, active coordination, and mutual respect were critical in prompting case-related conversations, but not in completing procedural checks. Findings highlight the importance of surgeon engagement and high-quality, consistent teamwork for promoting checklist use and ensuring a safe surgical environment.

    An operating room (OR) department has adopted an efficient business model and subsequently investigated how efficiency could be further improved. The aim of this study is to show the efficiency improvement of lowering organizational barriers and applying advanced mathematical techniques. We applied advanced mathematical algorithms in combination with scenarios that model relaxation of various organizational barriers using prospectively collected data. The setting is the main inpatient OR department of a university hospital, which sets its surgical case schedules 2 wk in advance using a block planning method. The main outcome measures are the number of freed OR blocks and OR utilization. Lowering organizational barriers and applying mathematical algorithms can yield a 4.5% point increase in OR utilization (95% confidence interval 4.0%-5.0%). This is obtained by reducing the total required OR time. Efficient OR departments can further improve their efficiency. The paper shows that a radical cultural change that comprises the use of mathematical algorithms and lowering organizational barriers improves OR utilization.

    Delays in starting first cases of the day are a common topic associated with high economic costs. This study aimed to determine if an operating room (OR) assistant using an instructional supervision program could reduce the tardiness of first-case starts. A prospective study was conducted. Data from four ORs were used to compare the effectiveness of an instructional intervention to reduce delays in starting first cases of the day. The first cases in two ORs received instructional supervision by an OR. The primary endpoint was the percentage of first cases that started on time. Other endpoints were the percentage of the team work score of OR staff and the percentage of patient satisfaction score. Over 48 weeks, the effect of instructional supervision was evaluated in 960 first-case starts. In the instructional supervision group (n = 480), the percentage of first cases that started on time increased significantly (92.1% vs 71.7%; P < .001), and there was a higher percentage of the team work score (84.4% vs 76.7%; P < .01) and patient satisfaction score (88.3% vs 79.4%; P < .001). Instructional supervision by an OR assistant can make a potential improvement in our on-time first-case starts per day. Copyright © 2016 American Society of PeriAnesthesia Nurses.

    Operating room (OR) efficiency continues to be a high priority for hospitals. In this context the concept of benchmarking has gained increasing importance as a means to improve OR performance. The aim of this study was to investigate whether and how participation in a benchmarking and reporting program for surgical process data was associated with a change in OR efficiency, measured through raw utilization, turnover times, and first-case tardiness. The main analysis is based on panel data from 202 surgical departments in German hospitals, which were derived from the largest database for surgical process data in Germany. Panel regression modelling was applied. Results revealed no clear and univocal trend of participation in a benchmarking and reporting program for surgical process data. The largest trend was observed for first-case tardiness. In contrast to expectations, turnover times showed a generally increasing trend during participation. For raw utilization no clear and statistically significant trend could be evidenced. Subgroup analyses revealed differences in effects across different hospital types and department specialties. Participation in a benchmarking and reporting program and thus the availability of reliable, timely and detailed analysis tools to support the OR management seemed to be correlated especially with an increase in the timeliness of staff members regarding first-case starts. The increasing trend in turnover time revealed the absence of effective strategies to improve this aspect of OR efficiency in German hospitals and could have meaningful consequences for the medium- and long-run capacity planning in the OR.

    Previous studies have indicated that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under regional anesthesia. In this study we sought to determine whether this decrease in sedative requirements results from music or from eliminating operating room (OR) noise. A secondary aim of the study was to examine the relationship of response to intraoperative music and participants' culture (i.e., American versus Lebanese). Eighty adults (36 American and 54 Lebanese) undergoing urological procedures with spinal anesthesia and patient-controlled IV propofol sedation were randomly assigned to intraoperative music, white noise, or OR noise. We found that, controlling for ambient OR noise, intraoperative music decreases propofol requirements (0.004 +/- 0.002 mg . kg(-1) . min(-1) versus 0.014 +/- 0.004 mg . kg(-1) . min(-1) versus 0.012 +/- 0.002 mg . kg(-1) . min(-1); P = 0.026). We also found that, regardless of group assignment, Lebanese patients used less propofol as compared with American patients (0.005 +/- 0.001 mg . kg(-1) . min(-1) versus 0.017 +/- 0.003 mg . kg(-1) . min(-1); P = 0.001) and that, in both sites, patients in the music group required less propofol (P noise, intraoperative music decreases propofol requirements of both Lebanese and American patients who undergo urological surgery under spinal anesthesia.

    This study compared two different laminar airflow distribution strategies - horizontal and vertical - and investigated the effectiveness of both ventilation systems in terms of reducing the sedimentation and distribution of bacteria-carrying particles. Three different staff clothing systems, which resulted in source strengths of 1.5, 4 and 5 CFU/s per person, were considered. The exploration was conducted numerically using a computational fluid dynamics technique. Active and passive air sampling methods were simulated in addition to recovery tests, and the results were compared. Model validation was performed through comparisons with measurement data from the published literature. The recovery test yielded a value of 8.1 min for the horizontal ventilation scenario and 11.9 min for the vertical ventilation system. Fewer particles were captured by the slit sampler and in sedimentation areas with the horizontal ventilation system. The simulated results revealed that under identical conditions in the examined operating room, the horizontal laminar ventilation system performed better than the vertical option. The internal constellation of lamps, the surgical team and objects could have a serious effect on the movement of infectious particles and therefore on postoperative surgical site infections.

    2008-01-01

    The present study aimed to identify firms supplying products to our university operating room (OR) that promote sustainable manufacturing methods. Results show that 72% of our suppliers, or 152 of 211 companies, do not promote sustainability practices in a salient manner. Multi-national firms document sustainability methods significantly more than U.S. divisions of multi-nationals or U.S. firms with chi-square = 157.93 (p sustainability promotion is an important marketing tool through which purchasers may begin the process of due diligence for product selection. Lack of sustainability information among suppliers in this study suggests that hospital procurement departments likely focus solely on issues like price or quality when making purchase decisions. These results also suggest an opportunity for healthcare administrators to evaluate more fully the products involved in the healthcare supply chain; the intrinsic, intangible value added to hospital products through sustainable manufacturing is consistent with responsible patient care and has the potential to create marketing and public relations value.

    2014-03-01

    As control rooms are modernized with new digital systems at nuclear power plants, it is necessary to evaluate the operator performance using these systems as part of a verification and validation process. There are no standard, predefined metrics available for assessing what is satisfactory operator interaction with new systems, especially during the early design stages of a new system. This report identifies the process and metrics for evaluating human system interfaces as part of control room modernization. The report includes background information on design and evaluation, a thorough discussion of human performance measures, and a practical example of how the process and metrics have been used as part of a turbine control system upgrade during the formative stages of design. The process and metrics are geared toward generalizability to other applications and serve as a template for utilities undertaking their own control room modernization activities.

    2009-06-01

    Tardiness from scheduled start times is a common source of frustration for both operating room (OR) personnel and patients. Factors that influence tardiness were quantified in a companion paper and have been used to develop interventions that have the potential for reducing tardiness. Data from two surgical suites were used to compare the effectiveness of several interventions to reduce tardiness, including i) moving cases to different ORs on the afternoon of surgery, ii) recalculating the OR schedule when it is published to correct for average lateness in first cases of the day, iii) recalculating the OR schedule when it is published to correct for average service-specific case duration bias, and iv) scheduling a gap (time buffer) before the cases of a "to follow" surgeon if the day is expected to end early. These last three interventions involve creation of a modified schedule with revised start times that are more accurate for both patient and "to follow" surgeon. The surgeon performing the first case of the day would not be affected. Moving cases to different ORs when a room was running late produced a 50%-70% reduction in the tardiness for those cases that were moved. However, overall tardiness in each suite was reduced by only 6%-9%, because few cases were moved. Scheduling a gap between surgeons if the day was expected to end early reduced tardiness by more than 50% for those cases that were preceded by gaps. However, overall tardiness in each suite was reduced by only 4%-8%, because few gaps could be scheduled. In contrast, correcting for the combination of lateness in first cases of the day and service-specific case duration bias reduced overall tardiness in each suite by 30%-35%. Interventions which involve small numbers of cases have little potential to reduce overall tardiness. Generating a modified or auxiliary OR schedule that compensates for known causes of tardiness can significantly reduce patient and "to follow" surgeon waiting times. Modifying

    The assurance of high standards of care is a major requirement in German hospitals while cost reduction and efficient use of resources are mandatory. These requirements are particularly evident in the high-risk and cost-intensive operating theatre field with multiple process steps. The cleaning of operating rooms (OR) between surgical procedures is of major relevance for patient safety and requires time and human resources. The hygiene procedure plan for OR cleaning between operations at the university hospital in Göttingen was revised and optimized according to the plan-do-check-act principle due to not clearly defined specifications of responsibilities, use of resources, prolonged process times and increased staff engagement. The current status was evaluated in 2012 as part of the first step "plan". The subsequent step "do" included an expert symposium with external consultants, interdisciplinary consensus conferences with an actualization of the former hygiene procedure plan and the implementation process. All staff members involved were integrated into this management change process. The penetration rate of the training and information measures as well as the acceptance and compliance with the new hygiene procedure plan were reviewed within step "check". The rates of positive swabs and air sampling as well as of postoperative wound infections were analyzed for quality control and no evidence for a reduced effectiveness of the new hygiene plan was found. After the successful implementation of these measures the next improvement cycle ("act") was performed in 2014 which led to a simplification of the hygiene plan by reduction of the number of defined cleaning and disinfection programs for preparation of the OR. The reorganization measures described led to a comprehensive commitment of the hygiene procedure plan by distinct specifications for responsibilities, for the course of action and for the use of resources. Furthermore, a simplification of the plan, a

    Clinical working environments have become very complex imposing many different tasks in diagnosis, medical treatment, and care procedures. During the German flagship project OR.NET, more than 50 partners developed technologies for an open integration of medical devices and IT systems in the operating room. The aim of the present work was to evaluate a large set of the proposed concepts from the perspectives of various stakeholders. The demonstration OR is focused on interventions from the head and neck surgery and was developed in close cooperation with surgeons and numerous colleagues of the project partners. The demonstration OR was qualitatively evaluated including technical as well as clinical aspects. In the evaluation, a questionnaire was used to obtain feedback from hospital operators. The clinical implications were covered by structured interviews with surgeons, anesthesiologists and OR staff. In the present work, we qualitatively evaluate a subset of the proposed concepts from the perspectives of various stakeholders. The feedback of the clinicians indicates that there is a need for a flexible data and control integration. The hospital operators stress the need for tools to simplify risk management in openly integrated operating rooms. The implementation of openly integrated operating rooms will positively affect the surgeons, the anesthesiologists, the surgical nursing staff, as well as the technical personnel and the hospital operators. The evaluation demonstrated the need for OR integration technologies and identified the missing tools to support risk management and approval as the main barriers for future installments.

    Full Text Available Introduction & Objective: Allergic reactions to natural rubber latex have increased during past 10 years especially among health care workers and patients with high exposure to latex allergens. Allergic reaction to latex is related to many diseases like occupational asthma. This study was performed to determine the prevalence of allergy to natural rubber latex and potential cross reacting food in operation room staff in Shiraz hospitals. Materials & Methods: In this cross-sectional descriptive study five hundred eighty operation room staff of ten private and state hospitals in Shiraz completed latex allergy questionnaire. They were questioned about personal history and previous history of latex sensitivity, symptoms of latex reactivity and about other allergies particularly to foods that may cross react with latex. Informed consent was obtained and skin prick testing was performed with natural rubber latex. Skin prick tests were done with three potentially cross reacting food (banana, Kiwi, and potato. The obtained data were analyzed with SPSS software and Chi-square test. Results: Among the 580 operation room workers 104 (17.9 % of participants were positive to latex skin test. We found a significant association between positive skin test to latex in operation room staff and atopy, urticaria and food allergy. Positive skin test to latex related to positive kiwi skin test (p<0.05. The prevalence did not vary by sex, age, education, surgical and non surgical glove users, history of contact dermatitis or smoking status. Conclusion: Latex allergy has a high prevalence in personnel of operation room. Evaluation of present symptom and prediction of future disease necessitate screening test in individuals at risk.

    Surgical site infection (SSI) contributes significantly to postoperative morbidity and mortality and greatly increases the cost of care. To identify the impact of workflow and personnel-related risk factors contributing to the incidence of SSIs in a large sample of neurological surgeries. Data were obtained using an enterprisewide electronic health record system, operating room, and anesthesia records for neurological procedures conducted between January 1, 2009, and November 30, 2012. SSI data were obtained from prospective surveillance by infection preventionists using Centers for Disease Control and Prevention definitions. A multivariate model was constructed and refined using backward elimination logistic regression methods. The analysis included 12 528 procedures. Most cases were elective (94.5%), and the average procedure length was 4.8 hours. The average number of people present in the operating room at any time during the procedure was 10.0. The overall infection rate was 2.3%. Patient body mass index (odds ratio, 1.03; 95% confidence interval [CI], 1.01-1.04) and sex (odds ratio, 1.36; 95% CI, 1.07-1.72) as well as procedure length (odds ratio, 1.19 per additional hour; 95% CI, 1.15-1.23) and nursing staff turnovers (odds ratio, 1.095 per additional turnover; 95% CI, 1.02-1.21) were significantly correlated with the risk of SSI. This study found that patient body mass index and male sex were associated with an increased risk of SSI. Operating room personnel turnover, a modifiable, work flow-related factor, was an independent variable positively correlated with SSI. This study suggests that efforts to reduce operating room turnover may be effective in preventing SSI. OR, operating roomSSI, surgical site infection.

    To illustrate the changes that are occurring in the rapidly growing field of pediatric sedation. In the USA and throughout the world, children receive sedation from a multitude of specialists with varying levels of training. The current pediatric sedation literature reflects a growing body of sedation literature by medical specialists other than anesthesiologists. This article will review the controversial use of propofol by nonanesthesiologists and the manner in which this varied group of providers along with government entities, regulatory agencies, and national organizations contribute to the continuing evolution of sedation practices. The number of diagnostic and therapeutic procedures performed on children outside of the operating room continues to increase. The growing body of pediatric sedation literature suggests anesthesiologists are no longer at the forefront of pediatric sedation training, education, and research. Articles published by nonanesthesiologists describe pediatric sedation services, safety, and quality initiatives, drugs, and original sedation research. Medications that were considered under the realm of anesthesiologists are utilized by nonanesthesiologists to provide sedation to children. Regulating and government agencies, including the Joint Commission and the Center for Medicaid and Medicare Services have recently issued statements on the oversight and practice of sedation. The direction of pediatric sedation is no longer solely under the leadership of anesthesiologists. The use of anesthetic agents, including propofol, have been administered by nonanesthesiologists and reported as safe and effective agents. Nonanesthesiologists and governmental and regulatory agencies influence the delivery of sedation services. The future direction of pediatric sedation will ultimately depend upon the ability of anesthesiologists to collaborate with specialists, hospital administrators, credentialing committees, and oversight agencies in order to

    The surgical clerkship is an integral part of third-year medical student education. The operating room (OR) is a heavily used setting, but it is unclear whether this setting is as effective as possible. To determine the role of the OR and potential improvements, it is necessary to analyze the perspectives of those involved, including surgeons, residents, and medical students. An electronic survey was distributed to the surgeons, surgical residents, and third-year medical students associated with Rutgers New Jersey Medical School. The questions were a combination of 5-point Likert scale questions and qualitative responses. The questions assessed the role of the OR, the information taught in the OR, the quality of the teaching and environment, and potential improvements. Attending surgeons and residents generally rated the OR more positively than medical students did. Medical students desired more hands-on participation and a greater focus on learning technical skills. In addition, most medical students rated the feedback and direct instruction in the OR as "poor." Furthermore, the attending surgeons and medical students disagreed about the main roles of the OR as well as the effectiveness of teaching in the OR. The medical students reported experiencing anxiety and intimidation in the OR and suggested several improvements, such as decreasing the length of the surgical clerkship. There is significant disagreement between the surgeons and residents and the medical students regarding the roles and effectiveness of learning in the OR. This may help explain the reported medical student dissatisfaction and frustrations with the surgical clerkship. Copyright © 2017 Association of Program Directors in Surgery.

    Desflurane has been used in paediatric patients for several surgical indications. This article analyses the efficacy and safety of desflurane for diagnostic-therapeutic procedures in remote areas far from operating room in a group of selected patients with no known associated respiratory disease. A retrospective analysis was performed on 2,072 general anaesthesia procedures stored in a computer database, in which desflurane was used in a Paediatric Pain Unit during the years 2013 and 2014. An analysis was also performed using the patient demographics, type of procedure, anaesthetic technique, type of airway management, patient cooperation, and incidence of anaesthetic complications. The study included 876 patients, with a mean age of 8.8 years. The main procedures were bone marrow aspirates (23%), lumbar punctures (20%), panendoscopies (15%), and colonoscopies (5%). Induction was intravenous with propofol (26%) or inhalation with sevoflurane in the remaining 74%. Maintenance consisted of remifentanil and desflurane at mean end tidal concentrations of 6.2±2.1%. The airway was managed through a nasal cannula or face mask in spontaneous ventilation. The effectiveness was 98%, and the incidence of side effects was 15%, which included agitation (6%), headache (4%), nausea-vomiting (3%), and laryngospasm (2%). The maintenance with desflurane (at concentrations close to the hypnotic-MAC in spontaneous ventilation) was effective, with a rapid recovery, and with a low incidence of adverse effects.

    Ideal tumor resection requires brain/spinal cord tumor interface separation in perfect and precise surgical planes within a few micrometers for radical tumor resection and maximum normal tissue preservation. Despite the availability of several dissection techniques, the search for additional alternatives and an ideal technique continues. We evaluated the feasibility and advantages of dissection using a No. 15-blade scalpel in special brain tumor surgery situations. We developed a leaf model wherein its outer layer is progressively dissected from its inner skeleton using a scalpel. An additional model used was a tomato wherein its skin was peeled off its pulp using the same technique. We developed an inexpensive leaf model. A scalpel knife was used in a microneurosurgical setting, and the leaf's outer layer is peeled off. The technique is then used in an operating room setup where surgery on extra-axial tumors like meningiomas and intra-axial brain and spinal cord tumors is done. A No. 15 scalpel was used for dissection between the layers of the Peltophorum pterocarpum leaf model. This dissection method was compared with other neurosurgical dissecting tools. We dissected 120-μm thick leaves into 2 layers with removal of an 18- to 55-μm thick layer. Leaving behind a transparent layer was possible using a No. 15 blade scalpel. Similarly, it was possible to preserve a 35- to 40-μm thick arachnoid layer that separated a meningioma from the underlying brain parenchyma. A scalpel with a sharp edge could be used to perform precise and fine dissection. The scalpel deserves to occupy a place of pride as a dissecting tool in neurosurgery. Copyright © 2017 Elsevier Inc.

    Context-aware systems for the operating room (OR) provide the possibility to significantly improve surgical workflow through various applications such as efficient OR scheduling, context-sensitive user interfaces, and automatic transcription of medical procedures. Being an essential element of such a system, surgical action recognition is thus an important research area. In this paper, we tackle the problem of classifying surgical actions from video clips that capture the activities taking place in the OR. We acquire recordings using a multi-view RGBD camera system mounted on the ceiling of a hybrid OR dedicated to X-ray-based procedures and annotate clips of the recordings with the corresponding actions. To recognize the surgical actions from the video clips, we use a classification pipeline based on the bag-of-words (BoW) approach. We propose a novel feature encoding method that extends the classical BoW approach. Instead of using the typical rigid grid layout to divide the space of the feature locations, we propose to learn the layout from the actual 4D spatio-temporal locations of the visual features. This results in a data-driven and non-rigid layout which retains more spatio-temporal information compared to the rigid counterpart. We classify multi-view video clips from a new dataset generated from 11-day recordings of real operations. This dataset is composed of 1734 video clips of 15 actions. These include generic actions (e.g., moving patient to the OR bed) and actions specific to the vertebroplasty procedure (e.g., hammering). The experiments show that the proposed non-rigid feature encoding method performs better than the rigid encoding one. The classifier's accuracy is increased by over 4 %, from 81.08 to 85.53 %. The combination of both intensity and depth information from the RGBD data provides more discriminative power in carrying out the surgical action recognition task as compared to using either one of them alone. Furthermore, the proposed non

    The performance of a room-temperature continuous-wave (CW) terahertz source based on intracavity difference-frequency generation in a mid-infrared (λ ∼ 6.8 µm) quantum cascade laser with a dual-upper-state active region is reported. The fabricated buried heterostructure device, with a two-section buried distributed feedback grating, operates at two mid-infrared wavelengths and demonstrates a terahertz output of 2.92 THz with a very low threshold current density of 0.89 kA/cm2 in pulsed operation. Consequently, despite an epitaxial-side-up mounting configuration, the device achieves CW operation at room temperature in which a low CW threshold current density of 1.3 kA/cm2 is obtained.

    Anesthesiology residency primarily emphasizes the development of medical knowledge and technical skills. Yet, nontechnical skills (NTS) are also vital to successful clinical practice. Elements of NTS are communication, teamwork, situational awareness, and decision making. The first 10 consecutive senior residents who chose to participate in this 2-week elective rotation of operating room (OR) management and leadership training were enrolled in this study, which spanned from March 2013 to March 2015. Each resident served as the anesthesiology officer of the day (AOD) and was tasked with coordinating OR assignments, managing care for 2 to 4 ORs, and being on call for the trauma OR; all residents were supervised by an attending AOD. Leadership and NTS techniques were taught via a standardized curriculum consisting of leadership and team training articles, crisis management text, and daily debriefings. Resident self-ratings and attending AOD and charge nurse raters used the Anaesthetists' Non-Technical Skills (ANTS) scoring system, which involved task management, situational awareness, teamwork, and decision making. For each of the 10 residents in their third year of clinical anesthesiology training (CA-3) who participated in this elective rotation, there were 14 items that required feedback from resident self-assessment and OR raters, including the daily attending AOD and charge nurse. Results for each of the items on the questionnaire were compared between the beginning and the end of the rotation with the Wilcoxon signed-rank test for matched samples. Comparisons were run separately for attending AOD and charge nurse assessments and resident self-assessments. Scaled rankings were analyzed for the Kendall coefficient of concordance (ω) for rater agreement with associated χ and P value. Common themes identified by the residents during debriefings were recurrence of challenging situations and the skills residents needed to instruct and manage clinical teams. For

  18. Thinking in three's: Changing surgical patient safety practices in the complex modern operating room

    The three surgical patient safety events,wrong site surgery,retained surgical items (RSI) and surgical fires are rare occurrences and thus their effects on the complex modern operating room (OR) are difficult to study.The likelihood of occurrence and the magnitude of risk for each of these surgical safety events are undefined.Many providers may never have a personal experience with one of these events and training and education on these topics are sparse.These circumstances lead to faulty thinking that a provider won't ever have an event or if one does occur the provider will intuitively know what to do.Surgeons are not preoccupied with failure and tend to usually consider good outcomes,which leads them to ignore or diminish the importance of implementing and following simple safety practices.These circumstances contribute to the persistent low level occurrence of these three events and to the difficulty in generating sufficient interest to resource solutions.Individual facilities rarely have the time or talent to understand these events and develop lasting solutions.More often than not,even the most well meaning internal review results in a new line to a policy and some rigorous enforcement mandate.This approach routinely fails and is another reason why these problems are so persistent.Vigilance actions alone have been unsuccessful so hospitals now have to take a systematic approach to implementing safer processes and providing the resources for surgeons and other stakeholders to optimize the OR environment.This article discusses standardized processes of care for mitigation of injury or outright prevention of wrong site surgery,RSI and surgical fires in an action-oriented framework illustrating the strategic elements important in each event and focusing on the responsibilities for each of the three major OR agents-anesthesiologists,surgeons and nurses.A Surgical Patient Safety Checklist is discussed that incorporates the necessary elements to bring these team

  19. Associated Roles of Perioperative Medical Directors and Anesthesia: Hospital Agreements for Operating Room Management.

    2015-12-01

    As reviewed previously, decision making can be made systematically shortly before the day of surgery based on reducing the hours of overutilized operating room (OR) time and tardiness of case starts (i.e., patient waiting). We subsequently considered in 2008 that such decision making depends on rational anesthesia-hospital agreements specifying anesthesia staffing. Since that prior study, there has been a substantial increase in understanding of the timing of decision making to reduce overutilized OR time. Most decisions substantively influencing overutilized OR time are those made within 1 workday before the day of surgery and on the day of surgery, because only then are ORs sufficiently full that case scheduling and staff assignment decisions affect overutilized OR time. Consequently, anesthesiologists can easily be engaged in such decisions, because generally they must be involved to ensure that the corresponding anesthesia staff assignments are appropriate. Despite this, at hospitals with >8 hours of OR time used daily in each OR, computerized recommendations are superior to intuition because of cognitive biases. Decisions need to be made by a Perioperative Medical Director who has knowledge of the principles of perioperative managerial decision making published in the scientific literature rather than by a committee lacking this competency. Education in the scientific literature, and when different analytical methods should be used, is important. The addition that we make in this article is to show that an agreement between an anesthesia group and a hospital can both reduce overutilized OR time and patient waiting: The anesthesia group and hospital will ensure, hourly, that, when there are case(s) waiting to start, the number of ORs in use for each service will be at least the number that maximizes the efficiency of use of OR time. Neither the anesthesia group nor the hospital will be expected to run more than that number of ORs without mutual agreement

    Full Text Available Aim: The aim of this randomized, single-blinded study was to evaluate the effects of noise on hemodynamic and neuroendocrine stress response by measuring the level of noise in the surgery rooms of patients undergoing knee operations under neuroaxial anesthesia. Gerec ve Yontem: We compared patient responses from two groups of patients: those undergoing knee operations in a surgery room where the noise level (measured in decibels is high, and those undergoing meniscus operations in a surgery room with lower noise levels. The STAI, the State-Trait Anxiety Inventory (STAI-1, and the anxiety test (STAI-2wereperformed at preoperative and postoperative periods. 20 ml of blood sample was taken for basal, intraoperative 30th minute, and postoperative 1st hour measurements. Systolic, diastolic, and mean arterial blood pressures were found to be higher in the high noise level group. ACTH levels were increased during the early postoperative period and became normal during the late postoperative period in the high noise level group whereas ACTH levels were significantly decreased in the low-noise level group. Basal cortisol levels were significantly higher in the high noise level group. HCRP, an inflammatory response mediator was found to be decreased in both groups. Early and late blood glucose levels were significantly higher in the high noise group. There was a greater increase in early and late blood glucose levels in the high noise group. In the postoperative period, although the state-trait anxiety inventory (STAI-2 levels being higher in patients subject to noisier environment determines how people feel independent of the conditions and state they are in, this result made us consider that the noise the patients were subjected to in the intraoperative period may cause a stress response. Discussion: As a result we believe that standard noise levels should be achieved by reducing the factors causing high noise levels in the operating room. This will

    2012-01-01

    Currently, there is a trend in nuclear power plants (NPPs) toward introducing digital and computer technologies into main control rooms (MCRs). Safe generation of electric power in NPPs requires reliable performance of cognitive tasks such as fault detection, diagnosis, and response planning. The digitalization of MCRs has dramatically changed the whole operating environment, and the ways operators interact with the plant systems. If the design and implementation of the digital technology is incompatible with operators' cognitive characteristics, it may have negative effects on operators' cognitive reliability. Firstly, on the basis of three essential prerequisites for successful cognitive tasks, a causal model is constructed to reveal the typical human performance issues arising from digitalization. The cognitive mechanisms which they impact cognitive reliability are analyzed in detail. Then, Bayesian inference is used to quantify and prioritize the influences of these factors. It suggests that interface management and unbalanced workload distribution have more significant impacts on operators' cognitive reliability.

    2012-01-01

    Communication variables that are associated with face-negotiation theory were examined in a sample of operating-room physicians. A survey was administered to anesthesiologists and surgeons at a teaching hospital in the southwestern United States to measure three variables commonly associated with face-negotiation theory: conflict-management style, face concern, and self-construal. The survey instrument that was administered to physicians includes items that measured these three variables in previous face-negotiation research with slight modification of item wording for relevance in the medical setting. The physician data were analyzed using confirmatory factor analysis, Pearson's correlations, and t-tests. Results of this initial investigation showed that variables associated with face-negotiation theory were evident in the sample physician population. In addition, the correlations were similar among variables in the medical sample as those found in previous face-negotiation research. Finally, t-tests suggest variance between anesthesiologists and surgeons on specific communication variables. These findings suggest three implications that warrant further investigation with expanded sample size: (1) An intercultural communication theory and instrument can be utilized for health communication research; (2) as applied in a medical context, face-negotiation theory can be expanded beyond traditional intercultural communication boundaries; and (3) theoretically based communication structures applied in a medical context could help explain physician miscommunication in the operating room to assist future design of communication training programs for operating-room physicians.

    Operating room (OR) scheduling information systems can decrease perioperative labor costs. Material management information systems can decrease perioperative inventory costs. We used computer simulation to investigate whether using the OR schedule to trigger purchasing of perioperative supplies is likely to further decrease perioperative inventory costs, as compared with using sophisticated, stand-alone material management inventory control. Although we designed the simulations to favor financially linking the information systems, we found that this strategy would be expected to decrease inventory costs substantively only for items of high price ($1000 each) and volume (>1000 used each year). Because expensive items typically have different models and sizes, each of which is used by a hospital less often than this, for almost all items there will be no benefit to making daily adjustments to the order volume based on booked cases. We conclude that, in a hospital with a sophisticated material management information system, OR managers will probably achieve greater cost reductions from focusing on negotiating less expensive purchase prices for items than on trying to link the OR information system with the hospital's material management information system to achieve just-in-time inventory control. In a hospital with a sophisticated material management information system, operating room managers will probably achieve greater cost reductions from focusing on negotiating less expensive purchase prices for items than on trying to link the operating room information system with the hospital's material management information system to achieve just-in-time inventory control.

    2006-07-01

    Intra-Operative Radiation Therapy (I.O.R.T.) is carried out with electron beams produced by a Linac (Linear Accelerator) generally used for conventional radiotherapy with external beam, or by dedicated accelerators that can be employed directly into an operating room. I.O.R.T. refers to the application of radiation during a surgical intervention, after the removal of a neoplastic mass. I.O.R.T. uses on the tumour area a direct irradiation, for the possible localisation of sub-clinic illness or macroscopic residue in the case of non-radical resection. Intra-Operative Radiotherapy foresees a single session only, generally preceded or followed by radiotherapy with external beam. It allows the achievement of a selective radiation boost on the tumour volume. In some cases, it can also be used as a one-time/stand alone treatment in initial cancer of small volume, or in unresectable malignancies for palliative purpose. The technical advantages of I.O.R.T. consist in the direct visual control of the target volume, and in the possibility to protect the healthy tissues by moving them away from the path of the radiation beam. The use of electron beams allows the administration of a homogeneous dose to a selected layer of tissues surrounding the tumour. The following professional staff forms the Operative Group: radiation oncologist, surgeon, anaesthetist, medical physicist, radiation technologist, nurse.The choice of a simulation geometry very similar to the clinical situation allows to evaluate radioprotection data very close to the real situation. For a fixed layout, an anthropomorphic phantom was positioned on the operating bed and a breast I.O.R.T. treatment was simulated positioning all the accessories of the operating room in their typical positions. A detailed dose mapping was performed with a Victoreen 450P ionisation chamber and with environment film-dosimeter on the walls of the operating room during the simulation of the clinical treatment.

    A phosphoric acid based composite material with core-shell microstructure has been developed to be used as a new electrolyte for fuel cells. A fuel cell based on this electrolyte can operate at room temperature indicating leaching of H{sub 3}PO{sub 4} with liquid water is insignificant at room temperature. This will help to improve the thermal cyclability of phosphoric acid based electrolyte to make it easier for practical use. The conductivity of this H{sub 3}PO{sub 4}-based electrolyte is stable at 250 C with addition of the hydrophilic inorganic compound BPO{sub 4} forming a core-shell microstructure which makes it possible to run a PAFC at a temperature above 200 C. The core-shell microstructure retains after the fuel cell measurements. A power density of 350 mW/cm{sup 2} for a H{sub 2}/O{sub 2} fuel cell has been achieved at 200 C. The increase in operating temperature does not have significant benefit to the performance of a H{sub 2}/O{sub 2} fuel cell. For the first time, a composite electrolyte material for phosphoric acid fuel cells which can operate in a wide range of temperature has been evaluated but certainly further investigation is required.

    To observe the anesthetic effect and safety of differential airway management in patients with mental retardation (MR) during autologous peripheral blood mononuclear cell transplantation (APBMCT) outside the operating room. In this prospective study, 30 uncooperative patients with MR receiving total intravenous anesthesia (TIVA) with propofol for APBMCT were randomized into 3 groups with monitored anesthesia care (MAC group), inserted classic laryngeal mask airway under general anesthesia (LMA group), or endotracheal tube placement (ETT group). The blood pressure (BP), heart rate (HR), SpO(2) and pH, PaCO(2), and HCO(3)(-) were monitored at 5 min and 1 h after anesthesia, before completion of the operation and at 1 h after the operation. The total operative time, dosage of propofol, awake time and body movement during the procedure were recorded. Compared with LMA and ETT groups, the MAC groups showed a significantly increased total dosage of propofol (66.07±5.41, 35.83±5.80, and 34.61±3.68 g·kg(-1)·min(-1), respectively, Pawake time (16.82±7.60, 4.31±1.32, and 3.73±1.33 min, P0.05). At 1 h after anesthesia, the pH in MAC group decreased markedly compared with that in LMA and ETT groups (PMAC group and remained so till the end of the surgery (P<0.05). Endotracheal tube placement is safer than laryngeal mask airway placement and monitored anesthesia care in patients with MR during APBMCT, and allows rapid onset of sedation with minimal cardiovascular responses, body movement and recovery, therefore is more suitable in the setting outside the operating room.

    The study was conducted from the perspective of human factors engineering in order to compare the process that operators originally used to diagnose potential and actual faults with a process that included an expert system for diagnosing faults. The results of the study indicated that the existence of an expert system for fault diagnosis makes the task of fault diagnosis easier and reduces errors by quickly suggesting likely Abnormal Operating Procedures (AOPs).

    Ventilation and air conditioning systems are necessary for developing proper parameters of indoor envi-ronment in operating rooms. The main task of ventilation and air conditioning in those specific areas consists in creating desirable temperature, reducing the number of microorganisms and the concen-trations of hazardous gases and substances in the air, as well as ensuring the proper direction of airflow. In Poland, indoor environment in operating rooms has to comply with the requirements se...

    This prospective randomized study compares the effects of rocuronium (R) and vecuronium (V) on the early postoperative period in infants. Forty-eight infants between the ages of three and six, scheduled for elective ENT procedures, were studied after prior approval of local ethics committee and informed parental consent. All children were premedicated with chlorprotixene and belladonna. Anaesthesia was induced with 5 mg/kg thiopentone and 1 vol.-% halothane. Subsequently, 0.4 mg/kg rocuronium or 0.075 mg/kg vecuronium were administered, respectively. Anaesthesia and post-operative care were conducted by independent anaesthetists, who were unaware of the drug used and of the relaxometric data obtained. All children were monitored in the recovery room by pulse oximetry until they reached a Steward Score of 6. Demographic data did not differ between the groups. No differences were recorded between the non-depolarizing relaxants regarding intubation time (R: 24.1 +/- 4.2 min, V: 25.8 +/- 6.8 min) and the time interval from end extubation to leaving the operating theatre (R: 2.3 +/- 0.8 min, V: 2.6 +/- 1.2 min), respectively. Similarly, no differences in SaO2 were noted during the recovery period in the recovery room. Significant differences between the non-depolarizing relaxants were found in the TOF-ratios at extubation (R: 0.73 +/- 0.31 min, V: 0.48 +/- 0.34 min) and arrival in the recovery room (R: 0.88 +/- 0.21 min, V: 0.69 +/- 0.26 min). 0.4 mg/kg Rocuronium and 0.075 mg/kg vecuronium can be used for intubation during short operations on pre-school children. Rocuronium may be the better alternative, due to its faster neuromuscular recovery properties.

    Full Text Available Introduction: The recovery ward is a vital unit to care patients awaking from anesthesia and is a standard requirement for the operating room. Recovery ward is located adjacent to the operation room and is easily accessible to trained and skilled individuals. The unit must have adequate equipment for surveillance and monitoring of patients and required medication should also be provided. Methods: This study is a cross-sectional conducted in one phase through referring to hospital facilities and equipment. Physical space, personnel and their skill levels and other factors that are involved in the care of patients in the recovery have been investigated. The instruments used in this study were a check list and observe sheet which were completed by the researchers. Data analysis was conducted by SPSS software. Results: The results showed that the standards of buildings and physical space in the researched areas were mostly nonstandard. Equipment standards were to some extent in line with the criteria set by American Association of Anesthesia. Besides, some equipment was blow standard levels. Personnel standards regarding the number of nurses toward the number of recovery beds did not meet the standard criteria in most of the cases. Conclusion: The research shows that building standards in most cases are not in line with mentioned references. Undertaking equipment standards in the hospital recovery wards needs reviewing and providing controlling equipment for preventing the complications of recovery phase of anesthesia in recovery wards.

    The contamination diffusion to the operating room when the door is open was simulated with a computational fluid dynamic (CFD) method,to give the extent of the contamination diffusion.The influence of the door-opening procedure was ignored since the door of the operating room is normally a sliding one.The flow field in the case of the 16 s course of opening the door was simulated.The simulated and the experimental results demonstrate that the extent of the contamination diffusion is around 1.5 m when there is no temperature difference between indoor and outdoor,and there is hardly any contamination diffusion when the temperature difference is 1 ℃.It can be concluded that the positive pressure difference in the operating room lost its function in preventing the contamination when the door is open.That the temperature of corridor is lower than that of operating room contributes to contamination control.Keeping 1 ℃ temperature difference between corridor and operating room and increasing positive pressure and air flow are suggested.It is more secure to set up an anteroom if persons come in or out of the operation room at the course of surgery.

    To assess the impact of a short hypnotic session on postoperative anxiety and pain in major orthopaedic surgery. Despite specific information given before a scheduled paediatric surgery, perioperative anxiety can become important. Randomised Clinical Study. The study is an open single-centre randomised clinical study comparing a "control" group versus a "hypnosis" group receiving a short hypnosis pre-induction session as additional experimental analgesic procedure. The primary endpoint was the postoperative anxiety, blindly assessed using a visual analogue scale. The study involved 120 children (age 10-18 years). The results showed no difference between control group versus hypnosis group. Twenty-four hours after surgery (Day+1), the patient's anxiety score was not different between control and hypnosis groups (median [Q1-Q3]: 1 [0; 3] vs. 0 [0; 3], respectively, p = .17). Each group experienced a significant decrease in anxiety level between the day before surgery (Day-1) and the day after surgery (Day+1) (median ([Q1-Q3]) difference of the anxiety score: 2 [4; 0] and 2 [4; 0], respectively, p < .0001 in each group). The postoperative pain scores were low and not different between groups (median [Q1-Q3]: 2 [0; 3] in control group vs. 3 [1; 3] in hypnosis group, p = .57). This randomised study on a short hypnosis session performed in the operating room prior to a major surgery showed no difference in postoperative anxiety and pain levels. The decrease in anxiety and pain levels may be due to the addition of nurse pre-operative interviews and optimisation in communication in the operating room. As postoperative anxiety level was low in both control and hypnosis groups, nurse pre-operative interviews and nurse training in hypnosis may contribute to the optimisation of global management and decrease the postoperative anxiety level. © 2017 John Wiley & Sons Ltd.

    Shift work is associated with both sleepiness and reduced performance. The aim of this study was to examine cognitive performance, sleepiness, and sleep quality among petrochemical control room shift workers. Sixty shift workers participated in this study. Cognitive performance was evaluated using a number of objective tests, including continuous performance test, n-back test, and simple reaction time test; sleepiness was measured using the subjective Karolinska Sleepiness Scale (KSS); and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. ANCOVA, t-test, and repeated-measures ANOVA were applied for statistical analyses, and the significance level was set at p sleep quality on both day and night shifts, and there were significant differences between the day and night shifts in terms of subjective sleep quality and quantity (p sleep, induced cognitive performance decline at the end of both day and night shifts, and increased sleepiness in night shift. It, thus, seems necessary to take ergonomic measures such as planning for more appropriate shift work and reducing working hours.

    Routine clinical information systems now have the ability to gather large amounts of data that surgical managers can access to create a seamless and proactive approach to streamlining operations and minimizing delays. The challenge lies in aggregating and displaying these data in an easily accessible format that provides useful, timely information on current operations. A Web-based, graphical dashboard is described in this study, which can be used to interpret clinical operational data, allow managers to see trends in data, and help identify inefficiencies that were not apparent with more traditional, paper-based approaches. The dashboard provides a visual decision support tool that assists managers in pinpointing areas for continuous quality improvement. The limitations of paper-based techniques, the development of the automated display system, and key performance indicators in analyzing aggregate delays, time, specialties, and teamwork are reviewed. Strengths, weaknesses, opportunities, and threats associated with implementing such a program in the perioperative environment are summarized.

    Electricity distribution network operation (NO) models are challenged as they are expected to continue to undergo changes during the coming decades in the fairly developed and regulated Nordic electricity market. Network asset managers are to adapt to competitive technoeconomical business models regarding the operation of increasingly intelligent distribution networks. Factors driving the changes for new business models within network operation include: increased investments in distributed automation (DA), regulative frameworks for annual profit limits and quality through outage cost, increasing end-customer demands, climatic changes and increasing use of data system tools, such as Distribution Management System (DMS). The doctoral thesis addresses the questions a) whether there exist conditions and qualifications for competitive markets within electricity distribution network operation and b) if so, identification of limitations and required business mechanisms. This doctoral thesis aims to provide an analytical business framework, primarily for electric utilities, for evaluation and development purposes of dedicated network operation models to meet future market dynamics within network operation. In the thesis, the generic build-up of a business model has been addressed through the use of the strategic business hierarchy levels of mission, vision and strategy for definition of the strategic direction of the business followed by the planning, management and process execution levels of enterprise strategy execution. Research questions within electricity distribution network operation are addressed at the specified hierarchy levels. The results of the research represent interdisciplinary findings in the areas of electrical engineering and production economics. The main scientific contributions include further development of the extended transaction cost economics (TCE) for government decisions within electricity networks and validation of the usability of the

    The importance of minimally invasive surgery (MIS) has constantly increased in the last 20 years. Laparoscopic removal of the gallbladder has become the gold standard with advantages for patients. However, in laparoscopy, the surgeon loses direct contact with the surgical site. Rather than seeing the entire surgical field including adjacent organs, the surgeon's vision is restricted by an optic and camera system. Pictures of the surgical site in the abdomen are presented on a monitor. Hand eye coordination is decreasing because the operating team is not able to position the monitor at an ergonomically preferable position given that operation tables, constructed for open surgery where surgeons use short instruments, are too high for laparoscopic procedures where surgeons use long-shafted instruments. Additionally the degrees of freedom for camera movements and the instruments are limited, tactile feedback given in open surgery is lost. The typical design of instrument handles leads to pressure areas and nerve lesions. All these aspects force the surgeon into unnatural and uncomfortable body postures that can affect the outcome of the operation. An ideal posture for laparoscopic surgeons is described and ergonomic requirements for an optimal height of operation tables, monitor positions and man-machine interfaces are discussed.

    Indoor environments, where people spend most of their time, are characterized by a specific microbial community, the indoor microbiome. Most indoor environments are connected to the natural environment by high ventilation, but some habitats are more confined: intensive care units, operating rooms, cleanrooms and the international space station (ISS) are extraordinary living and working areas for humans, with a limited exchange with the environment. The purposes for confinement are different: a patient has to be protected from infections (intensive care unit, operating room), product quality has to be assured (cleanrooms), or confinement is necessary due to extreme, health-threatening outer conditions, as on the ISS. The ISS represents the most secluded man-made habitat, constantly inhabited by humans since November 2000 - and, inevitably, also by microorganisms. All of these man-made confined habitats need to be microbiologically monitored and controlled, by e.g., microbial cleaning and disinfection. However, these measures apply constant selective pressures, which support microbes with resistance capacities against antibiotics or chemical and physical stresses and thus facilitate the rise of survival specialists and multi-resistant strains. In this article, we summarize the available data on the microbiome of aforementioned confined habitats. By comparing the different operating, maintenance and monitoring procedures as well as microbial communities therein, we emphasize the importance to properly understand the effects of confinement on the microbial diversity, the possible risks represented by some of these microorganisms and by the evolution of (antibiotic) resistances in such environments - and the need to reassess the current hygiene standards.

    Laser radiation in the wavelength range around 2 μm is required for its specific properties - it is very suitable for medical applications, remote sensing, or pumping of optical parametric oscillators to generate ultrafast pulses in the mid-IR region further exploited in nonlinear optics. Crystals as YLF, YAG, LLF, and GdVO4 doped by holmium were already investigated and found suitable for the tunable laser generation around 2.1 mμ. Only a few works are devoted to the laser operation of holmium-doped fluorides as CaF2. In this work, pulsed and continuous-wave laser operation of a modified- Bridgman-grown Ho:CaF2 active crystal at room temperature is reported. A commercial 50 W 1940 nm Tm-fiber laser was used to pump a laser oscillator based on a novel 10 mm long 0.5 at.% Ho:CaF2 active crystal placed in the Peltiercooled holder. In the pulsed regime (10 ms, 10 Hz), the laser slope efficiency of 53 % with respect to the absorbed pump power was achieved. The laser generated at the central wavelength of 2085 nm with the maximum mean output power of 365 mW corresponding to the power amplitude of 3.65 W. In the continuous wave regime, the maximum output power was 1.11 W with the slope efficiency of 41 % with respect to the absorbed pump power. To our best knowledge this is the first demonstration of this laser active material operating in the CW regime at room temperature. The tuning range over 60 nm from 2034 to 2094 nm was achieved using a birefringent filter showing the possibility to develop a mode-locked laser system generating pulses in the sub-picosecond range.

    There has been little in the development or application of operating room (OR) management metrics to non-operating room anesthesia (NORA) sites. This is in contrast to the well-developed management framework for the OR management. We hypothesized that by adopting the concept of physician efficiency, we could determine the applicability of this clinical productivity benchmark for physicians providing services for NORA cases at a tertiary care center. We conducted a retrospective data analysis of NORA sites at an academic, rural hospital, including both adult and pediatric patients. Using the time stamps from WiseOR® (Palo Alto, CA), we calculated site utilization and physician efficiency for each day. We defined scheduling efficiency (SE) as the number of staffed anesthesiologists divided by the number of staffed sites and stratified the data into three categories (SE 1). The mean physician efficiency was 0.293 (95% CI, [0.281, 0.305]), and the mean site utilization was 0.328 (95% CI, [0.314, 0.343]). When days were stratified by scheduling efficiency (SE 1), we found differences between physician efficiency and site utilization. On days where scheduling efficiency was less than 1, that is, there are more sites than physicians, mean physician efficiency (95% CI, [0.326, 0.402]) was higher than mean site utilization (95% CI, [0.250, 0.296]). We demonstrate that scheduling efficiency vis-à-vis physician efficiency as an OR management metric diverge when anesthesiologists travel between NORA sites. When the opportunity to scale operational efficiencies is limited, increasing scheduling efficiency by incorporating different NORA sites into a "block" allocation on any given day may be the only suitable tactical alternative.

    It has come to our attention that numerous devices that need charging adaptors during cardiopulmonary bypass (CPB) have similar charging sockets but different voltage requirements. This has caused one of our devices in the operating theater to overheat and completely shut down when connected to an incorrect higher-voltage charger. The possibility of fire, device destruction, or patient harm in such circumstances is of serious concern.

    Often in simulated settings, quantitative analysis of technical skill relies largely on specially tagged instruments or tracers on surgeons' hands. We investigated a novel, marker-less technique for evaluating technical skill during open operations and for differentiating tasks and surgeon experience level. We recorded the operative field via in-light camera for open operations. Sixteen cases yielded 138 video clips of suturing and tying tasks ≥5 seconds in duration. Video clips were categorized based on surgeon role (attending, resident) and task subtype (suturing tasks: body wall, bowel anastomosis, complex anastomosis; tying tasks: body wall, superficial tying, deep tying). We tracked a region of interest on the hand to generate kinematic data. Nested, multilevel modeling addressed the nonindependence of clips obtained from the same surgeon. Interaction effects for suturing tasks were seen between role and task categories for average speed (P = .04), standard deviation of speed (P = .05), and average acceleration (P = .03). There were significant differences across task categories for standard deviation of acceleration (P = .02). Significant differences for tying tasks across task categories were observed for maximum speed (P = .02); standard deviation of speed (P = .04); and average (P = .02), maximum (P < .01), and standard deviation (P = .03) of acceleration. We demonstrated the ability to detect kinematic differences in performance using marker-less tracking during open operative cases. Suturing task evaluation was most sensitive to differences in surgeon role and task category and may represent a scalable approach for providing quantitative feedback to surgeons about technical skill.

    Surgery can be a triumph of co-operation, the procedure evolving as a result of joint action between multiple participants. The communication that mediates the joint action of surgery is conveyed by verbal but particularly by non-verbal signals. Competing priorities superimposed by surgical learning must also be negotiated within this context and this paper draws on techniques of systemic functional linguistics to observe and analyse the flow of information during such a phase of surgery.

    BACKGROUND “War stories” are commonplace in surgical education, yet little is known about their purpose, construct, or use in the education of trainees. METHODS Ten complex operations were videotaped and audiotaped. Narrative stories were analyzed using grounded theory to identify emergent themes in both the types of stories being told and the teaching objectives they illustrated. RESULTS Twenty-four stories were identified in 9 of the 10 cases (mean, 2.4/case). They were brief (mean, 58 seconds), illustrative of multiple teaching points (mean, 1.5/story), and appeared throughout the operations. Anchored in personal experience, these stories taught both clinical (eg, operative technique, decision making, error identification) and programmatic (eg, resource management, professionalism) topics. CONCLUSIONS Narrative stories are used frequently and intuitively by physicians to emphasize a variety of intraoperative teaching points. They socialize trainees in the culture of surgery and may represent an underrecognized approach to teaching the core competencies. More understanding is needed to maximize their potential.

    To examine outcomes in patients who receive small amounts of intraoperative blood transfusion. Longitudinal, uncontrolled observational study evaluating results of intraoperative transfusion in patients entered into the American College of Surgeons National Surgical Quality Improvement Program database. We made propensity-matched comparisons between patients who received and did not receive intraoperative transfusion to minimize confounding when estimating the effect of intraoperative transfusion on postoperative outcomes. We queried the American College of Surgeons National Surgical Quality Improvement Program database for patients undergoing operations between January 1, 2005, and December 31, 2009. A large sample of surgical patients from 173 hospitals throughout the United States. Operative mortality and serious perioperative morbidity (≥1 of 20 complications). After exclusions, 941,496 operations were analyzed in patients from 173 hospitals. Most patients (893,205 patients [94.9%]) did not receive intraoperative transfusions. Patients who received intraoperative infusion of 1 unit of packed red blood cells (15,186 patients [1.6%]) had higher unadjusted rates of mortality and more serious morbidity. These rates further increased with intraoperative transfusion of more than 1 unit of packed red blood cells in a dose-dependent manner. After propensity matching to adjust for multiple preoperative risks, transfusion of a single unit of packed red blood cells increased the multivariate risk of mortality, wound problems, pulmonary complications, postoperative renal dysfunction, systemic sepsis, composite morbidity, and postoperative length of stay compared with propensity-matched patients who did not receive intraoperative transfusion. There is a dose-dependent adverse effect of intraoperative blood transfusion. It is likely that a small, possibly discretionary amount of intraoperative transfusion leads to increased mortality, morbidity, and resource use

    We operate a nitrogen vacancy (NV-) diamond magnetometer at ambient temperatures and study the dependence of its bandwidth on experimental parameters including optical and microwave excitation powers. We introduce an analytical theory that yields an explicit formula for the response of an ensemble of NV- spins to an oscillating magnetic field, such as in NMR applications. We measure a detection bandwidth of 1.6 MHz and a sensitivity of 4.6 nT/Hz^(1/2), unprecedented in a detector with this active volume and close to the photon shot noise limit of our experiment.

    The need for development of practices within the Finnish healthcare system is immense. Economic threats will force the system to streamline treatment processes without sacrificing quality. Surgical operations bind resources and represent one of the most expensive units in the hospital. By developing the respective procedures it is possible to achieve significant changes in the patient's entire care pathway. Lean is a practical management philosophy involving fairly expedient and structured methods of work development. On the basis of available research results and practical experiences Lean is very well suited for a method of development of practices within healthcare.

    Traumatic injury is the leading cause of potentially preventable lost years of life in the Western world and exsanguination is the most potentially preventable cause of post-traumatic death. With mature trauma systems and experienced trauma centres, extra-abdominal sites, such as the pelvis, constitute the most frequent anatomic site of exsanguination. Haemorrhage control for such bleeding often requires surgical adjuncts most notably interventional radiology (IR). With the usual paradigm of surgery conducted within an operating room and IR procedures within distant angiography suites, responsible clinicians are faced with making difficult decisions regarding where to transport the most physiologically unstable patients for haemorrhage control. If such a critical patient is transported to the wrong suite, they may die unnecessarily despite having potentially salvageable injuries. Thus, it seems only logical that the resuscitative operating room of the future would have IR capabilities making it the obvious geographic destination for critically unstable patients, especially those who are exsanguinating. Our trauma programme recently had the opportunity to conceive, design, build, and operationalise a purpose-designed hybrid trauma operating room, designated as the resuscitation with angiographic percutaneous techniques and operative resuscitation (RAPTOR) suite, which we believe to be the first such resource designed primarily to serve the exsanguinating trauma patient. The project was initiated after consultations between the trauma programme and private philanthropists regarding the greatest potential impacts on regional trauma care. The initial capital construction costs were thus privately generated but coincided with a new hospital wing construction allowing the RAPTOR to be purpose-designed for the exsanguinating patient. Many trauma programmes around the world are now starting to navigate the complex process of building new facilities, or else retrofitting

    Retained foreign bodies (RFBs) are a surgical complication resulting from foreign materials accidently left in a patient's body. This review attempts to give an overview of different types of RFBs, problems related to them and their management after the surgical operation. The internet was searched using the Google and Google scholar. In addition, relevant electronic journals from the University's library such as Entrez (including PubMed and PubMed central), Since Direct, Scirus, NIH.gov, Medknow.com, Medscape.com, Scopus, MedHelp.org, Cochrane library, WebMD.com, and World Health Organization Hinari. It shows that the major reasons of RFBs are emergency surgical operation with unplanned changes, patient high body mass index, and poor communication. To prevent this textile material should be radiopaque marked and must be counted once at the start and twice at the conclusion of all surgical procedures. If the count is incorrect, then radiography or manually re-exploration should be performed. Ultrasonography, computerized tomography, magnetic resonance imaging and radio frequency identification are also used in the proper identification of RFBs. Safety practice should be robust and simple enough to protect patient under the most chaotic of circumstances. Proper communication among the personnel participating in surgery aimed at preventing this medical negligence would help in mitigating such errors. Finally, the surgeon should not only follow the standard recommended procedure, but also report cases of RFBs.

TiO{sub 2} was prepared by sol–gel method and deposited on glass slides containing gold electrodes. Then, the film immersed in a 2.5 × 10{sup −4} M ethanol solution of cyanidin to absorb the pigment. The hybrid organic–inorganic formed film here can detect ammonia reversibly at room temperature. The relative change resistance of the films at a potential difference of 1.5 V is determined when the films are exposed to atmospheres containing ammonia vapors with concentrations over the range 10–50 ppm. The relative change resistance, S, of the films increased almost linearly with increasing concentrations of ammonia (r = 0.92). The response time to increasing concentrations of the ammonia is about 180–220 s, and the corresponding values for decreasing concentrations 240–270 s. At low humidity, ammonia could be ionized by the cyanidin on the TiO{sub 2} film and thereby decrease in the proton concentration at the surface. Consequently, more positively charged holes at the surface of the TiO{sub 2} have to be extracted to neutralize the adsorbed cyanidin and water film. The resistance response to ammonia of the sensors was nearly independent on temperature from 10 to 50 °C. These results are not actually as good as those reported in the literature, but this preliminary work proposes simpler and cheaper processes to realize NH{sub 3} sensor for room temperature applications.

    Invasive brain cancer cells cannot be visualized during surgery and so they are often not removed. These residual cancer cells give rise to recurrences. In vivo Raman spectroscopy can detect these invasive cancer cells in patients with grade 2 to 4 gliomas. The robustness of this Raman signal can be dampened by spectral artifacts generated by lights in the operating room. We found that artificial neural networks (ANNs) can overcome these spectral artifacts using nonparametric and adaptive models to detect complex nonlinear spectral characteristics. Coupling ANN with Raman spectroscopy simplifies the intraoperative use of Raman spectroscopy by limiting changes required to the standard neurosurgical workflow. The ability to detect invasive brain cancer under these conditions may reduce residual cancer remaining after surgery and improve patient survival.

  11. Use of operating room information system data to predict the impact of reducing turnover times on staffing costs.

    Potential benefits to reducing turnover times are both quantitative (e.g., complete more cases and reduce staffing costs) and qualitative (e.g., improve professional satisfaction). Analyses have shown the quantitative arguments to be unsound except for reducing staffing costs. We describe a methodology by which each surgical suite can use its own numbers to calculate its individual potential reduction in staffing costs from reducing its turnover times. Calculations estimate optimal allocated operating room (OR) time (based on maximizing OR efficiency) before and after reducing the maximum and average turnover times. At four academic tertiary hospitals, reductions in average turnover times of 3 to 9 min would result in 0.8% to 1.8% reductions in staffing cost. Reductions in average turnover times of 10 to 19 min would result in 2.5% to 4.0% reductions in staffing costs. These reductions in staffing cost are achieved predominantly by reducing allocated OR time, not by reducing the hours that staff work late. Heads of anesthesiology groups often serve on OR committees that are fixated on turnover times. Rather than having to argue based on scientific studies, this methodology provides the ability to show the specific quantitative effects (small decreases in staffing costs and allocated OR time) of reducing turnover time using a surgical suite's own data. Many anesthesiologists work at hospitals where surgeons and/or operating room (OR) committees focus repeatedly on turnover time reduction. We developed a methodology by which the reductions in staffing cost as a result of turnover time reduction can be calculated for each facility using its own data. Staffing cost reductions are generally very small and would be achieved predominantly by reducing allocated OR time to the surgeons.

    Aim. To perform a thorough and step-by-step assessment of operating room (OR) time utilization, with a view to assess the efficacy of our practice and to identify areas of further improvement. Materials and Methods. We retrospectively analyzed the most ordinary general surgery procedures, in terms of five intervals of OR time utilization: anaesthesia induction, surgery preparation, duration of operation, recovery from anaesthesia, and transfer to postanaesthesia care unit (PACU) or intensive care unit (ICU). According to their surgical impact, the procedures were defined as minor, moderate, and major. Results. A total of 548 operations were analyzed. The mean (SD) time in minutes for anaesthesia induction was 19 (9), for surgery preparation 13 (8), for surgery 115 (64), for recovery from anaesthesia 12 (8), and for transfer to PACU/ICU 12 (9). The time spent in each step presented an ascending escalation pattern proportional to the surgical impact (P = 0.000), which was less pronounced in the transfer to PACU/ICU (P = 0.006). Conclusions. Albeit, our study was conducted in a teaching hospital, the recorded time estimates ranged within acceptable limits. Efficient OR time usage and outliers elimination could be accomplished by a better organized transfer personnel service, greater availability of anaesthesia providers, and interdisciplinary collaboration.

    Effective teamwork is one of the essentials in conducting successful and safe surgical procedures in the operating theatre (OT). The present paper aims to provide a selective review of various approaches describing effective interdisciplinary teamwork in the OT. Furthermore, it covers observational methods to assess OT teamwork with particular focus on Germany. Our definition of successful surgical teamwork is based on an already established classification system considering five criteria for effective and safe OT teams: coordination, communication, cooperation, leadership, and team monitoring. Well-defined and reliable measures are necessary to examine the quality of OT teamwork. Those methods should entail the special characteristics of the OT team. They should include all phases of the surgical procedure and incorporate all the professions involved (surgeons, surgical nurses, and anaesthetic staff). We conclude that research into methods for the assessment of OTs in Germany needs to be undertaken as a prerequisite to investigating the relationship between OT teamwork and its effects on patient safety and surgical quality.

    To analyze the changes in the composition of the gynecologic oncology inpatient ward following the implementation of a robotic surgery program and its impact on inpatient resource utilization and costs. Retrospective review of the medical charts of patients admitted onto the gynecologic oncology ward the year prior to and five years after the implementation of robotics. The following variables were collected: patient characteristics, hospitalization details (reason for admission and length of hospital stay), and resource utilization (number of hospitalization days, consultations, and imaging). Following the introduction of robotic surgery, there were more admissions for elective surgery yet these accounted for only 21% of the inpatient ward in terms of number of hospital days, compared to 36% prior to the robotic program. This coincided with a sharp increase in the overall number of patients operated on by a minimally invasive approach (15% to 76%, probotics era. The robotics program contributed to a ward with higher proportion of patients with complex comorbidities (Charlson≥5: RR 1.06), Stage IV disease (RR 1.30), and recurrent disease (RR 1.99). Introduction of robotic surgery allowed for more patients to be treated surgically while simultaneously decreasing inpatient resource use. With more patients with non-surgical oncological issues and greater medical complexity, the gynecologic oncology ward functions more like a medical rather than surgical ward after the introduction of robotics, which has implications for hospital-wide resource planning.

    Error in health services delivery has long been recognised as a significant cause of inpatient morbidity and mortality. Root-cause analyses have cited communication failure as one of the contributing factors in adverse events. The formalised fighter pilot mission brief and debrief formed the basis of the National Aeronautics and Space Administration (NASA) crew resource management (CRM) concept produced in 1979. This is a qualitative analysis of our experience with the briefing-debriefing process applied to cardiac theatres. We instituted a policy of formal operating room (OR) briefing and debriefing in all cardiac theatre sessions. The first 118 cases were reviewed. A trouble-free operation was noted in only 28 (23.7%) cases. We experienced multiple problems in 38 (32.2%) cases. A gap was identified in the second order problem solving in relation to instrument repair and maintenance. Theatre team members were interviewed and their comments were subjected to qualitative analysis. The collaborative feeling is that communication has improved. The health industry may benefit from embracing the briefing-debriefing technique as an adjunct to continuous improvement through reflective learning, deliberate practice and immediate feedback. This may be the initial step toward a substantive and sustainable organizational transformation.

  20. Structure-oriented versus process-oriented approach to enhance efficiency for emergency room operations: what lessons can we learn?

    The efficiency and quality of a healthcare system can be defined as interactions among the system structure, processes, and outcome. This article examines the effect of structural adjustment (change in floor plan or layout) and process improvement (critical pathway implementation) on performance of emergency room (ER) operations for acute cerebral infarction patients. Two large teaching hospitals participated in this study: Korea University (KU) Guro Hospital and KU Anam Hospital. The administration of Guro adopted a structure-oriented approach in improving its ER operations while the administration of Anam employed a process-oriented approach, facilitating critical pathways and protocols. To calibrate improvements, the data for time interval, length of stay, and hospital charges were collected, before and after the planned changes were implemented at each hospital. In particular, time interval is the most essential measure for handling acute stroke patients because patients' survival and recovery are affected by the promptness of diagnosis and treatment. Statistical analyses indicated that both redesign of layout at Guro and implementation of critical pathways at Anam had a positive influence on most of the performance measures. However, reduction in time interval was not consistent at Guro, demonstrating delays in processing time for a few processes. The adoption of critical pathways at Anam appeared more effective in reducing time intervals than the structural rearrangement at Guro, mainly as a result of the extensive employee training required for a critical pathway implementation. Thus, hospital managers should combine structure-oriented and process-oriented strategies to maximize effectiveness of improvement efforts.

    Inappropriate staff behaviours can lead to environmental contamination in the operating room (OR) and subsequent surgical site infection (SSI). This study will focus on the continued assessment of OR staff behaviours using a motion tracking system and their impact on the SSI risk during surgical procedures. This multicentre prospective cross-sectional study will include 10 ORs of cardiac and orthopaedic surgery in 12 healthcare facilities (HCFs). The staff behaviour will be assessed by an objective, continued and prolonged quantification of movements within the OR. A motion tracking system including eight optical cameras (VICON-Bonita) will record the movements of reflective markers placed on the surgical caps/hoods of each person entering the room. Different configurations of markers positioning will be used to distinguish between the staff category. Doors opening will be observed by means of wireless inertial sensors fixed on the doors and synchronised with the motion tracking system. We will collect information on the OR staff, surgical procedures and surgical environment characteristics. The behavioural data obtained will be compared (1) to the 'best behaviour rules' in the OR, pre-established using a Delphi method and (2) to surrogates of the infectious risk represented by microbiological air counts, particle counts, and a bacteriological sample of the wound at closing. Statistics will be performed using univariate and multivariate analysis to adjust on the aerolic and architectural characteristics of the OR. A multilevel model will allow including surgical specialty and HCFs effects. Through this study, we will develop an original approach using high technology tools associated to data processing techniques to evaluate 'automatically' the behavioural dynamics of the OR staff and their impact on the SSI risk.

    The World Health Organization's surgical safety checklist is designed to improve adherence to operating room safety standards, and its use has been shown to reduce complications among surgical patients. The objective of our study was to assess the impact of the implementation of the checklist on safety-related issues in the operating room and on postoperative adverse events in neurosurgery. From structured questionnaires delivered to operating room personnel, answers were analyzed to evaluate communication and safety-related issues during 89 and 73 neurosurgical operations before and after the checklist implementation, respectively. From the analyzed operations, 83 and 67 patients, respectively, were included in a retrospective analysis of electronic patient records to compare the length of hospital stay, reported adverse events, and readmissions. In addition, the consistency of operating room documentation and patient records was assessed. Communication between the surgeon and the anesthesiologist was enhanced, and safety-related issues were better covered when the checklist was used. Unplanned readmissions fell from 25% to 10% after the checklist implementation (p = 0.02). Wound complications decreased from 19% to 8% (p = 0.04). The consistency of documentation of the diagnosis and the procedure improved. The use of the checklist improved safety-related performance and, contemporarily, reduced numbers of wound complications, and readmissions were observed.

    While policy changes toward early extubation in the operating room (OR) have been commonly seen in palliative surgeries in single ventricle anatomy, no systematic assessment of their impact on patient outcome has been reported. All patients aged 0-17 years admitted to a PICU in a quaternary children's hospital for post-operative management following a primary Fontan procedure between 2005 and 2011 were included. Patients for revision of Fontan or patients admitted to adult Cardiovascular Intensive Care Unit were excluded. Practice policy was changed from routine extubation in the PICU to early extubation in OR in January 2008. Data were compared between the pre-policy-change era (2005-2007) and the post-policy-change era (2008-2011) to assess the impact of the change on patient outcomes. Generalized linear regression (GLM) and interrupted time series (ITS) analysis were used to access the effect of policy change on PICU length of stay and post-operative fluid balance, adjusting for potential confounders using propensity scores. Root cause analysis (RCA) was conducted to describe causes of failed extubation and challenges of this policy change. One hundred twenty-seven children met inclusion criteria. Average body weight was 14.7 kg [standard deviation (SD) 3.9], and age was 3.5 years (SD 1.9). A clear change in extubation practice occurred between the pre- versus post-policy-change eras: 97.5 % were extubated in the PICU in the pre-policy-change era, as compared to 15.0 % in the post-policy-change era. The average PICU length of stay was shortened by 4.1 days from the pre-policy-change era to the post-policy-change era [95 % CI -1.2 to -6.9, p extubation in the current practice.

    Full Text Available BACKGROUND The objective of this study was to determine the contamination rate of the healthcare workers’ (HCWs’ mobile phones in operating room and identify strategies for their safe use within clinical areas. This study also to determine whether a standardized disinfecting protocol decreased the rate of bacterial contamination. METHODS This is a cross-sectional study that included all Health care workers with mobile phones in operation theatre. Samples for culture were collected from mobile phones with swab stick before and after disinfection of mobile phones with 2% isopropyl alcohol swab and transported for microbiological identification using Amies medium. Quantification of bacteria was performed using both surface spread isolated bacterial agents were identified using standard microbiological methods. RESULTS Total of 92 samples studied from 46 mobiles, out of 46 mobile phones tested (89% 41 were contaminated with either single or mixed bacterial agents. The most prevalent bacterial contaminants were Coagulase-Negative Staphylococci (CONS and E. coli representing 36% and 23%, respectively. After cleaning of mobile phone with 2% isopropyl alcohol decreases contamination to 50%. The mean bacterial count was 357 CFU/ml, while the median was 13 CFU/ml using the pour plate method. The corresponding figures were 2,192 and 1,720 organisms/phone using the surface spread method. CONCLUSION It is important to be conscious of the fact that mobile phone usage in Operation Theater is easily contaminated. Because cleaning with alcohol swabs prevents the contamination of the mobile phones. Mobile communication devices have an invaluable feature of communication within hospital health care providers should take standard precautions to minimize the contamination of mobile phones.

    ABSTRACT The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases. PMID:27812640

    Full Text Available Introduction & Objective: Surgical wound infection is one of the common nosocomial infections. During operation, members of the surgical team which are in contact with the tissue incision should observe the standards of infection control in the operating room since it has a great role in prevention and control of these infections. The present study aimed to determine the performance of the operating room personnel in observing the standards of infection control in educational hospitals of Yasuj University of Medical Sciences in 2009. Materials & Methods: Forty two operating room personnel participated in this cross-sectional analytic-descriptive study. A check list was used for unnoticeably collecting the data about the performance of personnel in respect of infection control standards at three different times. Their performances were classified into four levels (very weak, weak, moderate and good and the results were shown as absolute and relative frequency distribution. Data were analyzed using Chi-square and Fischer exact test by the SPSS software. Results: Performance of personnel in following the standards of infection control in this study was moderate. Conclusion: The results indicate that the participants of the study do not follow some of the standards of infection control in the operating rooms. Therefore, further activities of the committees of infection control and using of new antiseptic for surgical scrub are recommended.

    Full Text Available Nanostructured ZrO2 powder was synthesized by microwave assisted sol-gel method. The material was characterized by XRD and SEM techniques. X-Ray diffraction studies confirm that a combination of tetragonal and monoclinic zirconia nanoparticles is obtained by using microwave-assisted method. The nanopowder was calcined at an optimized temperature of 400 °C for 3 h. The prepared powder had crystalline size about 25 nm. Thick films of synthesized ZrO2 powder were prepared by screen printing technique. The gas sensing performances of these films for various gases were tested. Films showed highest response to H2 (50 ppm gas at room temperature with poor responses to others (1000 ppm. The quick response and fast recovery are the main features of this sensor. The effects of microstructure, operating temperature and gas concentration on the gas response, selectivity, response time and recovery time of the sensor in the presence of H2 gas and others were studied and discussed.

    Investigators of our research facility generally accept the concept of asepsis as an important component of adequate surgical care for animals. However, they experience difficulties putting it into practice, especially in the case of rodents. The reasons for this are inconvenience, cost, and lack of training. To better assist investigators in the implementation of aseptic surgical techniques in their laboratories, we have created an Operating Room (OR) Committee modeled after OR committees found in human hospitals. A reconstructive surgeon, a veterinarian, a research scientist, a nurse involved in the training of OR personnel, interns, graduate students, and an animal health technician were chosen as committee members in light of their OR and animal care expertise. The first task of the OR Committee was to establish institutional guidelines for aseptic surgery, taking into account the costs imposed on research budgets by these procedures. The OR Committee also supports a complete training program in aseptic surgery techniques, which consists of lectures, a training manual, videos, and a practical course. Furthermore, when experimental procedures require specialized equipment, the OR Committee collaborates with researchers to develop strategies to achieve asepsis. This OR Committee and the training program proved to be important tools to promote and improve the quality of animal care during surgery.

    Transfer of intensive care unit (ICU) patients to the operating room (OR) is a resource-intensive, time-consuming process that often results in patient throughput inefficiencies, deficiencies in information transfer, and suboptimal nurse to patient ratios. This study evaluates the implementation of a coordinated patient transport system (CPTS) designed to address these issues. Using data from 1,557 patient transfers covering the 2006-2010 period, interrupted time series and before and after designs were used to analyze the effect of implementing a CPTS at Mayo Clinic, Rochester. Using a segmented regression for the interrupted time series, on-time OR start time deviations were found to be significantly lower after the implementation of CPTS (p < .0001). The implementation resulted in a fourfold improvement in on-time OR starts (p < .01) while significantly reducing idle OR time (p < .01). A coordinated patient transfer process for moving patient from ICUs to ORs can significantly improve OR efficiency, reduce nonvalue added time, and ensure quality of care by preserving appropriate care provider to patient ratios.

    Occupational exposure to waste anesthetic gases in operating room (OR) without active scavenging system has been associated with adverse health effects. Thus, this study aimed to compare the trace concentrations of the inhaled anesthetics isoflurane and sevoflurane in OR with and without central scavenging system. Waste concentrations of isoflurane and sevoflurane were measured by infrared analyzer at different locations (near the respiratory area of the assistant nurse and anesthesiologist and near the anesthesia station) and at two times (30 and 120minutes after the start of surgery) in both OR types. All isoflurane and sevoflurane concentrations in unscavenged OR were higher than the US recommended limit (2 parts per million), regardless of the location and time evaluated. In scavenged OR, the average concentrations of isoflurane were within the limit of exposure, except for the measurements near the anesthesia station, regardless of the measurement times. For sevoflurane, concentrations exceeded the limit value at all measurement locations and at both times. The exposure to both anesthetics exceeded the international limit in unscavenged OR. In scavenged OR, the concentrations of sevoflurane, and to a lesser extent those of isoflurane, exceeded the recommended limit value. Thus, the OR scavenging system analyzed in the present study decreased the anesthetic concentrations, although not to the internationally recommended values.

    The purposes of this study were to determine the current attitude of orthopaedic trauma surgeons toward device sales representatives (DSRs), especially regarding their presence in the operating room (OR), and to establish the existence of any surgeon generational differences. A survey was created using a 5-point Likert response scale, related to conflict of interest (COI) and attitudes toward DSRs. Participants were solicited from the Orthopaedic Trauma Association database of 384 active members and 127 (33%) completed the survey. Respondents were divided into 2 subcategories (Generation X vs. Baby Boomers). Overall, respondents viewed their DSRs favorably without any perception of COI. However, they perceived their peers as being at risk for COI (P ≤ 0.004). Generation X responders feel that DSRs should be in the OR for all cases, whereas Baby Boomers do not (P < 0.01). With one striking generational difference, most orthopaedic trauma surgeons feel that they need DSRs in the OR. Similar to other physician groups, they also feel that they are not subject to COI from salesman contact that affects their peers. Reasons for this perceived need and any related COI risk, and the opportunities to address both, require further study.

    Background Anesthesiology requires performing visually-oriented procedures while monitoring auditory information about a patient’s vital signs. A concern in operating rooms environments is the amount of competing information and the effects that divided attention have on patient monitoring, such as detecting auditory changes in arterial oxygen saturation via pulse oximetry. Methods We measured the impact of visual attentional load and auditory background noise on the ability of anesthesia residents to monitor the pulse oximeter auditory display in a laboratory setting. Accuracies and response times were recorded reflecting anesthesiologists’ abilities to detect changes in oxygen saturation across three levels of visual attention in quiet and with noise. Results Results show that visual attentional load substantially impacts the ability to detect changes in oxygen saturation levels conveyed by auditory cues signaling 99 and 98% saturation. These effects are compounded by auditory noise, with up to a 17% decline in performance. These deficits are seen in the ability to accurately detect a change in oxygen saturation and in speed of response. Conclusions Most anesthesia accidents are initiated by small errors that cascade into serious events. Lack of monitor vigilance and inattention are two of the more commonly cited factors. Reducing such errors is thus a priority for improving patient safety. Specifically, efforts to reduce distractors and lower background noise should be considered during induction and emergence, periods of especially high risk, when anesthesiologists must attend to many tasks and are thus susceptible to error.

    Patients often wait to have urgent or emergency surgery. The number of operating rooms (ORs) needed to minimize waiting time while optimizing resources can be determined using queuing theory and computer simulation. We developed a computer program using Monte Carlo simulation to determine the number of ORs needed to minimize patient wait times while optimizing resources. We used patient arrival data and surgical procedure length from our institution, a tertiary-care academic medical center that serves a large diverse population. With ~4800 patients/year requiring non-elective surgery, and mean procedure length 185 min (median 150 min) we determined the number of ORs needed during the day and evening (0600-2200) and during the night (2200-0600) that resulted in acceptable wait times. Simulation of 4 ORs at day/evening and 3 ORs at night resulted in median wait time = 0 min (mean = 19 min) for emergency cases requiring surgery within 2 h, with wait time at the 95th percentile = 109 min. Median wait time for urgent cases needing surgery within 8-12 h was 34 min (mean = 136 min), with wait time at the 95th percentile = 474 min. The effect of changes in surgical length and volume on wait times was determined with sensitivity analysis. Monte Carlo simulation can guide decisions on how to balance resources for elective and non-elective surgical procedures.

    Lung recruitment maneuver induces a decrease in stroke volume, which is more pronounced in hypovolemic patients. The authors hypothesized that the magnitude of stroke volume reduction through lung recruitment maneuver could predict preload responsiveness. Twenty-eight mechanically ventilated patients with low tidal volume during general anesthesia were included. Heart rate, mean arterial pressure, stroke volume, and pulse pressure variations were recorded before lung recruitment maneuver (application of continuous positive airway pressure of 30 cm H2O for 30 s), during lung recruitment maneuver when stroke volume reached its minimal value, and before and after volume expansion (250 ml saline, 0.9%, infused during 10 min). Patients were considered as responders to fluid administration if stroke volume increased greater than or equal to 10%. Sixteen patients were responders. Lung recruitment maneuver induced a significant decrease in mean arterial pressure and stroke volume in both responders and nonresponders. Changes in stroke volume induced by lung recruitment maneuver were correlated with those induced by volume expansion (r = 0.56; P recruitment maneuver predicted fluid responsiveness with a sensitivity of 88% (95% CI, 62 to 98) and a specificity of 92% (95% CI, 62 to 99). Pulse pressure variations more than 6% before lung recruitment maneuver discriminated responders with a sensitivity of 69% (95% CI, 41 to 89) and a specificity of 75% (95% CI, 42 to 95). The area under receiver operating curves generated for changes in stroke volume induced by lung recruitment maneuver (0.96; 95% CI, 0.81 to 0.99) was significantly higher than that for pulse pressure variations (0.72; 95% CI, 0.52 to 0.88; P recruitment maneuver could predict preload responsiveness in mechanically ventilated patients in the operating room.

    Although electronic health record (EHR) systems have potential benefits, such as improved safety and quality of care, most ophthalmology practices in the United States have not adopted these systems. Concerns persist regarding potential negative impacts on clinical workflow. In particular, the impact of EHR operating room (OR) management systems on clinical efficiency in the ophthalmic surgery setting is unknown. To determine the impact of an EHR OR management system on intraoperative nursing documentation time, surgical volume, and staffing requirements. For documentation time and circulating nurses per procedure, a prospective cohort design was used between January 10, 2012, and January 10, 2013. For surgical volume and overall staffing requirements, a case series design was used between January 29, 2011, and January 28, 2013. This study involved ophthalmic OR nurses (n = 13) and surgeons (n = 25) at an academic medical center. Electronic health record OR management system implementation. (1) Documentation time (percentage of operating time documenting [POTD], absolute documentation time in minutes), (2) surgical volume (procedures/time), and (3) staffing requirements (full-time equivalents, circulating nurses/procedure). Outcomes were measured during a baseline period when paper documentation was used and during the early (first 3 months) and late (4-12 months) periods after EHR implementation. There was a worsening in total POTD in the early EHR period (83%) vs paper baseline (41%) (P system implementation was associated with worsening of intraoperative nursing documentation time especially in shorter procedures. However, it is possible to implement an EHR OR management system without serious negative impacts on surgical volume and staffing requirements.

    Full Text Available Ventilation and air conditioning systems are necessary for developing proper parameters of indoor envi-ronment in operating rooms. The main task of ventilation and air conditioning in those specific areas consists in creating desirable temperature, reducing the number of microorganisms and the concen-trations of hazardous gases and substances in the air, as well as ensuring the proper direction of airflow. In Poland, indoor environment in operating rooms has to comply with the requirements set out in three regulations (Journal of Laws of 2002 No. 75, item 690, as amended, Journal of Laws of 2002 No. 217, item 1833, Journal of Laws of 2011 No. 31, item 158, as amended and the document entitled "Guidelines for the design of general hospitals". Given insufficient accuracy of the abovementioned national documents, it is a common practice to use foreign standards, i.e. ASHRAE Standard 170-2013, DIN 1946-4: 2008 and FprCEN TR 16244: 2011. When considering the conditions for thermal comfort, it is important to bear in mind a close link between air flow velocity and air temperature. Air in the zone occupied by patients and medical staff must not cause the sensation of draft. Furthermore, air velocity should be sufficient to eliminate interference caused by the presence of people and other sources of heat. It should also reduce the turbulence level in the air in the operating room. Efficient functioning of ventilation and air conditioning was tested during treatments and operations carried out on three wards of a Warsaw hospital. Tests were performed with the participation of medical staff from various surgical units. They were asked to perform minor manual tasks to simulate work on the op-erating table, and to complete a questionnaire on subjective thermal sensation. The applied methodology is widely used during testing of general and local ventilation in public buildings. Air temperature, relative humidity, air flow supply and exhaust air from the

    The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. Alternatives for staff assignment optimization have been published in numerous publications dealing with the importance of OR management. In this connection the issue of material logistics in the context of OR management has not been frequently addressed. In order to perform a surgical procedure according to plan, one depends on personnel and on timely availability of the materials needed. Supply of sterilized materials is of utmost importance, because in most hospitals sterilized surgical devices constitute a critical resource. In order to coordinate the OR process with the production flow of sterilized materials, an organizational connection to the OR management makes sense. Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

    Effective biofilm inactivation using a handheld, mobile plasma jet powered by a 12 V dc battery and operated in open air without any external gas supply is reported. This cold, room-temperature plasma is produced in self-repetitive nanosecond discharges with current pulses of ˜100 ns duration, current peak amplitude of ˜6 mA and repetition rate of ˜20 kHz. It is shown that the reactive plasma species penetrate to the bottom layer of a 25.5 µm-thick Enterococcus faecalis biofilm and produce a strong bactericidal effect. This is the thickest reported biofilm inactivated using room-temperature air plasmas.

    2016-06-01

    To make good decisions, operating room (OR) managers often act autocratically after obtaining expert advice. When such advice is provided by e-mail, attachments of research articles can be included. We performed a quasi-experimental study using an evaluation of 4 articles used in a 50-hour OR management course to assess how their content influences trust in the article's content, including its quality, usefulness, and reliability. There were (a) 2 articles containing data with specific examples of application for health systems and 2 without and (b) 2 articles containing appendices of formulas and 2 without. Some of the formulas in the readings were relatively complicated (e.g., stochastic optimization using the Lagrange method) and unlikely to be used by the subjects (i.e., they show what does not need to be done). Content complexity (±data, ±formulas) served both as sources of limitation in understanding the content and potentially as peripheral cues influencing perception of the content. The 2-page evaluation forms were generated with random sequences of articles and response items. The N = 17 subjects each completed 9 items about each of the 4 articles (i.e., answered 36 questions). The 9-item assessment of trust provided a unidimensional construct (Cronbach α, 0.94). Formulas in the articles significantly increased trust in the information (P = 0.0019). Presence of data did not significantly influence trust (P = 0.15). Therefore, when an expert sends e-mail to a manager who has completed this basic OR management science and asks a question, choosing a paper with formulas has no disadvantage.

    Data envelopment analysis (DEA) is an established technique that hospitals and anesthesia groups can use to understand their potential to grow different specialties of inpatient surgery. Often related decisions such as recruitment of new physicians are made promptly. A practical challenge in using DEA in practice for this application has been the time to obtain access to and preprocess discharge data from states. A case study is presented to show how results of DEA are linked to financial analysis for purposes of deciding which surgical specialties should be provided more resources and institutional support, including the allocation of additional operating room (OR) block time on a tactical (1 yr) time course. State discharge abstract databases were used to study how to perform and present the DEA using data from websites of the United States' (US) Healthcare Cost and Utilization Project (HCUPNet) and Census Bureau (American FactFinder). DEA was performed without state discharge data by using census data with federal surgical rates adjusted for age and gender. Validity was assessed based on multiple criteria, including: satisfaction of statistical assumptions, face validity of results for hospitals, differentiation between efficient and inefficient hospitals on other measures of how much surgery is done, and correlation of estimates of each hospital's potential to grow the workload of each of eight specialties with estimates obtained using unrelated statistical methods. A hospital can choose specialties to target for expanded OR capacity based on its financial data, its caseloads for specific specialties, the caseloads from hospitals previously examined, and surgical rates from federal census data.

    Development and full validation of a laparoscopic training program for stepwise learning of a reproducible application of a standardized laparoscopic anastomosis technique and integration into the clinical course. The training of vesicourethral anastomosis (VUA) was divided into six simple standardized steps. To fix the objective criteria, four experienced surgeons performed the stepwise training protocol. Thirty-eight participants with no previous laparoscopic experience were investigated in their training performance. The times needed to manage each training step and the total training time were recorded. The integration into the clinical course was investigated. The training results and the corresponding steps during laparoscopic radical prostatectomy (LRP) were analyzed. Data analysis of corresponding operating room (OR) sections of 793 LRP was performed. Based on the validity, criteria were determined. In the laboratory section, a significant reduction of OR time for every step was seen in all participants. Coordination: 62%; longitudinal incision: 52%; inverted U-shape incision: 43%; plexus: 47%. Anastomosis catheter model: 38%. VUA: 38%. The laboratory section required a total time of 29 hours (minimum: 16 hours; maximum: 42 hours). All participants had shorter execution times in the laboratory than under real conditions. The best match was found within the VUA model. To perform an anastomosis under real conditions, 25% more time was needed. By using the training protocol, the performance of the VUA is comparable to that of an surgeon with experience of about 50 laparoscopic VUA. Data analysis proved content, construct, and prognostic validity. The use of stepwise training approaches enables a surgeon to learn and reproduce complex reconstructive surgical tasks: eg, the VUA in a safe environment. The validity of the designed system is given at all levels and should be used as a standard in the clinical surgical training in laparoscopic reconstructive urology.

    Full Text Available Background & Objectives: Anesthetic equipments could be one of the factors transmitting infection in a surgical operation. We could be prevent infection transmission to a great extend, by providing efficient methods of disinfection of anesthetic equipments. The purpose of the present research is to analyze the bacterial contamination in anesthetic equipment in operation rooms of Vali-e-Asr hospital in Fasa city, Fars province, and evaluate the efficiency of the applied disinfection methods. Materials & Methods: In this cross-sectional & analytical study, sampling from anesthetic equipment was done by sterile swap and culture on nutrient media, irregularly and randomly, before and after using and washing tools. Used anesthetic equipment in such operation rooms have been washed with Betadine 7.5% by experts and technicians of anesthetic section and were prepared for the next operation. Results: Total contamination was 2.3% in 210 samples taken. 5 culture items indicated the existence of bacterial contamination, among which 2 contamination cases were observed in nasal airway (coagulase negative Staphylococcus, non pathogen Neisseria, 2 contamination cases in red rubber endotracheal tube (nonpathogen Neisseria and Klebsiella pneumonia and 1 contamination case in oxygen mask (Escherichia coli. Conclusion: The very low level of contamination (20-85% contamination in anesthetic equipments in our research is probably due to application of a appropriate disinfection method used by educated personnel in operation rooms. This could have a significant role in decreasing the infection rate in one hand and decreasing expenses and time on the other hand.

    Given the benefit of glucose control in the perioperative period, we evaluated the accuracy and performance of the continuous glucose monitoring system (CGMS) depending on different measurement sites in the operating room (OR) and in the intensive care unit (ICU). Patients over 18 years of age scheduled for elective surgery and ICU admission were enrolled prospectively. Two CGMS sensors were inserted into the subcutaneous tissue of the proximal lateral thigh and the lateral abdomen. The rate of successful measurements from thigh and abdomen in the OR and in the ICU were calculated separately. Each CGMS values were compared with the time-matched arterial blood glucose measurements. CGMS values from both measurement sites were also compared. A total of 22 patients undergoing cardiac surgeries were studied. The rate of successful measurements was higher in the ICU (73.2 %) than in the OR (66.0 %) (P = 0.01); however, that from thigh (72.9 %) and from abdomen (58.7 %) showed statistically significant difference only in the OR (P = 0.04). The Pearson correlation coefficient of thigh and abdomen versus arterial values was 0.67 and 0.60, respectively (P < 0.001). In Clarke error grid analysis, 94.6 % (89.3 % in the OR and 96.1 % in the ICU) of values from thigh fell into clinically acceptable zones compared to 93.7 % (89.0 % in the OR and 95.4 % in the ICU) from abdomen. There were no statistically significant differences in the accuracy according to measurement sites. The CGMS showed high measurement failure rate, especially in the OR. In the OR, the rate of successful measurement was higher from thigh than from abdomen. The CGMS showed low accuracy compared to arterial reference values. Nevertheless, there was no difference in the accuracy of the CGMS between two measurement sites. Perioperative performance of the CGMS still needs to be improved considering relatively low successful measurement rates.

    Full Text Available Abstract Background No systematic process has previously been described for a needs assessment that identifies the operating room (OR management decisions made by the anesthesiologists and nurse managers at a facility that do not maximize the efficiency of use of OR time. We evaluated whether event-based knowledge elicitation can be used practically for rapid assessment of OR management decision-making at facilities, whether scenarios can be adapted automatically from information systems data, and the usefulness of the approach. Methods A process of event-based knowledge elicitation was developed to assess OR management decision-making that may reduce the efficiency of use of OR time. Hypothetical scenarios addressing every OR management decision influencing OR efficiency were created from published examples. Scenarios are adapted, so that cues about conditions are accurate and appropriate for each facility (e.g., if OR 1 is used as an example in a scenario, the listed procedure is a type of procedure performed at the facility in OR 1. Adaptation is performed automatically using the facility's OR information system or anesthesia information management system (AIMS data for most scenarios (43 of 45. Performing the needs assessment takes approximately 1 hour of local managers' time while they decide if their decisions are consistent with the described scenarios. A table of contents of the indexed scenarios is created automatically, providing a simple version of problem solving using case-based reasoning. For example, a new OR manager wanting to know the best way to decide whether to move a case can look in the chapter on "Moving Cases on the Day of Surgery" to find a scenario that describes the situation being encountered. Results Scenarios have been adapted and used at 22 hospitals. Few changes in decisions were needed to increase the efficiency of use of OR time. The few changes were heterogeneous among hospitals, showing the usefulness of

    Inter-professional teamwork in the operating room is important for patient safety. The World Health Organization (WHO) checklist was introduced to improve intraoperative teamwork. The aim of this study was to evaluate the safety climate in a Swedish operating room setting before and after an intervention, using a revised version of the WHO checklist to improve teamwork. This study is a single center prospective interventional study. Participants were personnel working in operating room teams including surgeons, anesthesiologists, scrub nurses, nurse anaesthetists and nurse assistants. The study started with pre-interventional observations of the WHO checklist use followed by education on safety climate, the WHO checklist, and non-technical skills in the operating room. Thereafter a revised version of the WHO checklist was introduced. Post-interventional observations regarding the performance of the WHO checklist were carried out. The Safety Attitude Questionnaire was used to assess safety climate at baseline and post-intervention. At baseline we discovered a need for improved teamwork and communication. The participants considered teamwork to be important for patient safety, but had different perceptions of good teamwork between professions. The intervention, a revised version of the WHO checklist, did not affect teamwork climate. Adherence to the revision of the checklist was insufficient, dominated by a lack of structure. There was no significant change in teamwork climate by use of the revised WHO checklist, which may be due to insufficient implementation, as a lack of adherence to the WHO checklist was detected. We found deficiencies in teamwork and communication. Further studies exploring how to improve safety climate are needed. NCT02329691.

    We developed a contactless interface that exploits hand gestures to effectively control medical images in the operating room. We developed an in-house program called GestureHook that exploits message hooking techniques to convert gestures into specific functions. For quantitative evaluation of this program, we used gestures to control images of a dynamic biliary CT study and compared the results with those of a mouse (8.54 ± 1.77 s to 5.29 ± 1.00 s; p < 0.001) and measured the recognition rates of specific gestures and the success rates of tasks based on clinical scenarios. For clinical applications, this program was set up in the operating room to browse images for plastic surgery. A surgeon browsed images from three different programs: CT images from a PACS program, volume-rendered images from a 3D PACS program, and surgical planning photographs from a basic image viewing program. All programs could be seamlessly controlled by gestures and motions. This approach can control all operating room programs without source code modification and provide surgeons with a new way to safely browse through images and easily switch applications during surgical procedures.

    Management of recurrent respiratory papillomatosis (RRP) in adults has evolved to include office-based laser techniques. To determine whether demographic or disease characteristics differ between patients undergoing office-based (office group) vs traditional operating room (OR group) surgical approaches for RRP. This study was a medical record review of adult patients with RRP treated between January 2011 and September 2013 at a tertiary care center. Patients were divided into 2 groups according to the setting in which the patient had the most procedures during the past 2 years. Demographic and disease characteristics were compared between patients receiving predominantly office-based vs predominantly OR management. Of 57 patients (47 male and 10 female, with a mean [SD] age of 53.5 [16.4] years) treated during the 2-year period, 34 patients underwent predominantly office-based management and 23 patients underwent predominantly OR management. Sex, age, and weight were not statistically significantly different between the 2 groups. Patients in the OR group had a younger age at RRP diagnosis (mean [SD], 28.7 [22.0] years in the OR group and 45.5 [20.5] years in the office group), with a mean difference of 16.8 years (95% CI, -28.3 to -5.4 years). Patients in the OR group also had a significantly higher Derkay score (mean [SD], 15.1 [5.7] in the OR group and 10.7 [5.0] in the office group), with a mean difference of 4.4 (95% CI, 1.6-7.3). No statistically significant differences in comorbidities were observed between the 2 groups except for type 1 or 2 diabetes, which was more common in the OR group. There were 5 patients (22%) with diabetes in the OR group and 1 patient (3%) with diabetes in the office group, with a mean difference of 19% (95% CI, 2.7%-35%). In a subanalysis that excluded patients with juvenile-onset RRP, Derkay score (mean [SD], 13.9 [4.5] in the OR group and 10.8 [5.1] in the office group), with a mean difference of 3.1 (95% CI, 0.5-6.1), and the

    The Petrus line is installed in Hall 40, of Unit 4 of Building 18 at the CEA centre at Fontenay-aux-Roses. It was used for the production of transuranic elements between 1970 and July 1995, when operations in Building 18 ended. The Petrus cell, which was in place until 1965, was replaced by the shielded Petrus line at the late sixties. It was connected to two vulcathene effluent tanks (1 and 2), each with a capacity of 1 m{sup 3}, located on the second sub-level of the building in a room referred to as the 'former Petrus tank room'. These tanks were supplied by a main pipe shielded with 15 cm of lead located in the upstream adit. The content of these tanks was extracted via the intermediate tank to the Circe zone, held at a negative pressure differential and located in the downstream adit, at an intermediate level relative to level 0. From this tank, liquors were removed by suction with tank truck pumps. The Petrus line is also connected to three stainless steel tanks (A, B and C), with a capacity of 0.5 m{sup 3} each, located in the same room as the vulcathene tanks. The former tank room is entered via a lobby connected to the room by a lead plug door. The tank room is severely contaminated.

    2003-07-01

    Surgeons using the same amount of operating room (OR) time differ in their achieved hospital contribution margins (revenue minus variable costs) by >1000%. Thus, to improve the financial return from perioperative facilities, OR strategic decisions should selectively focus additional OR capacity and capital purchasing on a few surgeons or subspecialties. These decisions use estimates of each surgeon's and/or subspecialty's contribution margin per OR hour. The estimates are subject to uncertainty (e.g., from outliers). We account for the uncertainties by using mean-variance portfolio analysis (i.e., quadratic programming). This method characterizes the problem of selectively expanding OR capacity based on the expected financial return and risk of different portfolios of surgeons. The assessment reveals whether the choices, of which surgeons have their OR capacity expanded, are sensitive to the uncertainties in the surgeons' contribution margins per OR hour. Thus, mean-variance analysis reduces the chance of making strategic decisions based on spurious information. We also assess the financial benefit of using mean-variance portfolio analysis when the planned expansion of OR capacity is well diversified over at least several surgeons or subspecialties. Our results show that, in such circumstances, there may be little benefit from further changing the portfolio to reduce its financial risk. Surgeon and subspecialty specific hospital financial data are uncertain, a fact that should be taken into account when making decisions about expanding operating room capacity. We show that mean-variance portfolio analysis can incorporate this uncertainty, thereby guiding operating room management decision-making and reducing the chance of a strategic decision being made based on spurious information.

    Lan, Rong; Xu, Xiaoxiang; Tao, Shanwen; Irvine, John T. S.

    A phosphoric acid based composite material with core-shell microstructure has been developed to be used as a new electrolyte for fuel cells. A fuel cell based on this electrolyte can operate at room temperature indicating leaching of H 3PO 4 with liquid water is insignificant at room temperature. This will help to improve the thermal cyclability of phosphoric acid based electrolyte to make it easier for practical use. The conductivity of this H 3PO 4-based electrolyte is stable at 250 °C with addition of the hydrophilic inorganic compound BPO 4 forming a core-shell microstructure which makes it possible to run a PAFC at a temperature above 200 °C. The core-shell microstructure retains after the fuel cell measurements. A power density of 350 mW/cm 2 for a H 2/O 2 fuel cell has been achieved at 200 °C. The increase in operating temperature does not have significant benefit to the performance of a H 2/O 2 fuel cell. For the first time, a composite electrolyte material for phosphoric acid fuel cells which can operate in a wide range of temperature has been evaluated but certainly further investigation is required.

    Full Text Available n a knitting- confection profile factory, any activity oriented toward evaluation, maintenance or improvement of products quality level is based on measuring and examining the product quality characteristics, in order to establish conformity to the quality specifications and/or naming the non-quality characteristics (establishing defects and fabrication deficiencies. We can consider non-quality as complementary to quality, although a definitive distinction cannot always be made between the two categories or states. Cutting holds a key role in insuring shape precision and pieces dimensions, determining the quality of the confection process, its structure and manual stages frequency. The quality of the cutting operation, appreciated through the precision and aspect of cut contours, existence and precision of markings, is directly reflected in the finite product’s quality, which entails knowledge of cutting instrument - fabric interactions. In compliance of the technological regime during the operations in the cutting room can determine: incorrect marking, spreading, sectioning or cutting. Non-quality of intermediate products obtained in the cutting department can be evaluated and controlled through defectologic control methods.The De – Ca – Re method (defect-cause-remedy correlation, applied in this paper, allows establishing the most important causes that generate defects, as well as preventive and corrective actions to eliminate these causes. This paper systematically presents the main defects that may occur during operations in the cutting room, causes that generate these defects, along with their preventive and corrective actions.

    2007-01-01

    We evaluated the effects of a behavioral treatment on the safe passing of sharp instruments using the hands-free technique among hospital operating room personnel during surgical procedures. Treatment consisted of participative goal setting, task clarification, and feedback. The average percentage of sharp instruments passed safely increased from 32% to 64% and 31% to 70% between baseline and treatment phases in the inpatient and outpatient surgery units, respectively. Five-month follow-up data suggested maintenance of treatment effects. These findings suggest the utility of organizational behavior management strategies in reducing risky behavior in hospital settings. PMID:18189098

    We report direct observations of Rabi oscillations and self-induced transparency in a quantum dot optical amplifier operating at room temperature. The experiments make use of pulses whose durations are shorter than the coherence time which are characterized using Cross-Frequency-Resolved Optical Gating. A numerical model which solves the Maxwell and Schrödinger equations and accounts for the inhomogeneously broadened nature of the quantum dot gain medium confirms the experimental results. The model is also used to explain the relationship between the observability of Rabi oscillations, the pulse duration and the homogeneous and inhomogeneous spectral widths of the semiconductor.

    A low level of air-borne bacteria in the operating room air can be achieved if all staff wear clothes made of low-permeability material (i.e. clean air suits). This study investigated if there was a difference in protective efficacy between two single-use scrubs made of polypropylene by testing them during routinely performed orthopaedic surgical procedures. No significant difference in the colony-forming unit count/m(3) air was found between the two scrubs, so the choice can be based on which scrub type is more comfortable for staff.

    To determine if reversing a deep or moderate block with sugammadex, compared with a shallow block reversed with neostigmine, reduces the time to operating room discharge after surgery and the time spent in the postanesthesia care unit. A randomized controlled trial. Monocentric study performed from February 2011 until May 2012. One hundred consenting women with American Society of Anesthesiologists grade I or II were randomized into 2 groups. Laparoscopic hysterectomy was performed under desflurane general anesthesia. For the neostigmine (N) group, 0.45 mg · kg(-1) rocuronium was followed by spontaneous recovery. A 5-mg rescue bolus was administered only if surgical evaluation was unacceptable. At the end of surgery, 50 μg · kg(-1) neostigmine with glycopyrrolate was administered. For the sugammadex (S) group, a higher intubating rocuronium dose (0.6 mg · kg(-1)) was followed by 5-mg boluses each time the train-of-four count exceeded 2. Sugammadex (2-4 mg · kg(-1)) was administered to reverse the block. All patients were extubated after obtaining a train-of-four ratio of 0.9. The duration between the end of surgery and operating room discharge and the time spent in the postanesthesia care unit. The time till operating room discharge was shorter and more predictable in group S (9.15±4.28 minutes vs 13.87±11.43 minutes in group N; P=.005). The maximal duration in group S was 22 minutes, compared with 72 minutes in group N. The time spent in the postanesthesia care unit was not significantly different (group S: 47.75±31.77 minutes and group N: 53.43±40.57 minutes; P=.543). Maintaining a deep neuromuscular block during laparoscopic hysterectomy reversed at the end of the procedure with sugammadex enabled a faster and more predictable time till operating room discharge than did the classical combination of a shallower block reversed with neostigmine.

    Achieving surgical hemostasis plays a major role in the operating room. Occasionally, classical surgical techniques are ill suited or fail to achieve the desired control at the site of bleeding. Topical hemostasis may be seen as a useful addition to assist the surgeon in controlling surgical bleeding. To provide a brief overview of available topical hemostatic agents with a focus on the different formulations of thrombin. The scope of the review was limited to a keyword search on PubMed and Ovid (surgical hemostasis, thrombin, tissue adhesives). Proven as adjuncts to surgical hemostasis, topical hemostatic agents have become quite valuable to bridge or to achieve permanent hemostasis.

    The intraoperative identification of small pulmonary nodules through video-assisted thoracoscopic surgery remains challenging. Although preoperative CT-guided nodule localization is commonly used to detect tumors during video-assisted thoracoscopic surgery (VATS), this approach carries inherent risks. We report the case of a patient with stage I lung cancer presenting as an area of ground-glass opacity (GGO) in the right upper pulmonary lobe. He successfully underwent a single-stage, CT-guided localization and removal of the pulmonary nodule within a hybrid operating room (OR) equipped with a robotic C-arm.

    Operating room nurses are at high risk for occupational exposure to bloodborne pathogens. This study examined the prevalence of and risk factors for needlestick injuries (NSIs), sharps injuries (SIs), and blood and body fluid exposures (BBFEs) among operating room nurses in Thai hospitals. A cross-sectional study was performed in 247 Thai hospitals. Questionnaires eliciting demographic data and information on injury occurrence and risk factors were distributed to 2500 operating room nurses, and 2031 usable questionnaires were returned, for a response rate of 81.2%. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multiple logistic regression analysis. The prevalence of NSIs, SIs, and BBFEs was 23.7%, 9.8%, and 40.0%, respectively. Risk factors for NSIs were training without practice (OR, 1.67; 95% CI, 1.29-2.17), haste (OR, 4.81; 95% CI, 3.41-6.79), lack of awareness (OR, 1.36; 95% CI, 1.04-1.77), inadequate staffing (OR, 1.60; 95% CI, 1.21-2.11), and outdated guidelines (OR, 1.69; 95% CI, 1.04-2.74). One risk factor was identified for SIs: haste (OR, 2.43; 95% CI, 1.57-3.76). Risk factors for BBFEs were long working hours per week (OR, 2.07; 95% CI, 1.06-4.04), training without practice (OR, 1.55; 95% CI, 1.25-1.91), haste (OR, 1.66; 95% CI, 1.30-2.13), lack of awareness (OR, 1.54; 95% CI, 1.22-1.95), not wearing protective equipment (OR, 1.61; 95% CI, 1.26-2.06), and inadequate staffing (OR, 1.63; 95% CI, 1.26-2.11). This study highlights the high prevalence of NSIs, SIs, and BBFEs among Thai operating room nurses. Preventable risk factors were identified. Appropriate guidelines, adequate staffing, proper training, and self-awareness may reduce these occurrences. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

The purpose of this study is to retrospectively review the factors associated with hospital readmission after EVAR. Methods The 2013 EVAR targeted American College of Surgeons (ACS-NSQIP) database and generalized 2013 general and vascular surgery ACS-NSQIP participant use files were used for this study. Patient, diagnosis, and procedure characteristics of patients undergoing EVAR surgery were assessed. Multivariate logistic regression analysis was used to determine independent risk factors for hospital readmission within 30 days after surgery. Results A total of 2277 patients (81% males, 19% females) underwent EVAR operations in the year 2013. Indications for operations included: asymptomatic large diameter (79%), symptomatic (5.7%), rupture without hypotension (4.3%), and rupture with hypotension (2.8%). Among these patients, 178 (7.8%) were readmitted to the hospital within 30 days after surgery. About 53% of all readmissions were within two weeks after the discharge. Risk factors, associated with readmission included: body mass index (per 5-units, OR 1.23, CI 1.06-1.42, p return to the operating room (OR 11.29, CI 6.29-20.28, p Risk of readmission for patients with presence of all these seven factors was 99.9%. Conclusions Readmission after EVAR is a serious occurrence. Various factors predispose a patient at a high risk for readmission. Unplanned return to operating room after EVAR is associated with a 11-fold increase in hospital readmission.

    The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases. RESUMO O conceito de sala híbrida traduz a união de um aparato cirúrgico de alta complexidade com recursos radiológicos de última geração (ultrassom, TC, radioscopia e/ou ressonância magnética), visando a realização de procedimentos minimamente invasivos e altamente eficazes. Apesar de bem estabelecido em outras especialidades, como neurocirurgia e cirurgia cardiovascular, o uso da sala hibrida ainda é pouco explorado na cirurgia torácica. Nosso objetivo foi discutir as aplicações e as possibilidades abertas por essa tecnologia na cirurgia torácica através do relato de três casos.

    The authors report on the design, fabrication and operation of heterogeneous and compact "2.5 D" Photonic Crystal microlaser with a single plane of InAs quantum dots as gain medium. The high quality factor photonic structures are tailored for vertical emission. The devices consist of a top two-dimensional InP Photonic Crystal Slab, a SiO(2) bonding layer, and a bottom high index contrast Si/SiO(2) Bragg mirror deposited on a Si wafer. Despite the fact that no more than about 5% of the quantum dots distribution effectively contribute to the modal gain, room-temperature lasing operation, around 1.5 microm, was achieved by photopumping. A low effective threshold, on the order of 350 microW, and a spontaneous emission factor, over 0.13, could be deduced from experiments.

    Indium nitrate/polyvinyl pyrrolidone (In(NO3)3/PVP) composite nanofibers were synthesized via electrospinning, and then hollow structure indium oxide (In2O3) nanofibers were obtained through calcination with PVP as template material. In situ polymerization was used to prepare indium oxide/polyaniline (In2O3/PANI) composite nanofibers with different mass ratios of In2O3 to aniline. The structure and morphology of In(NO3)3/PVP, In2O3/PANI composite nanofibers and pure PANI were investigated by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM) and current-voltage (I-V) measurements. The gas sensing properties of these materials towards NH3 vapor (100 to 1000 ppm) were measured at room temperature. The results revealed that the gas sensing abilities of In2O3/PANI composite nanofibers were better than pure PANI. In addition, the mass ratio of In2O3 to aniline and the p-n heterostructure between In2O3 and PANI influences the sensing performance of the In2O3/PANI composite nanofibers. In this paper, In2O3/PANI composite nanofibers with a mass ratio of 1:2 exhibited the highest response values, excellent selectivity, good repeatability and reversibility.

    A membraneless direct electron transfer (DET)-type dihydrogen (H2)/air-breathing biofuel cell without any mediator was constructed wherein bilirubin oxidase from Myrothecium verrucaria (BOD) and membrane-bound [NiFe] hydrogenase from Desulfovibrio vulgaris Miyazaki F (MBH) were used as biocatalysts for the cathode and the anode, respectively, and Ketjen black-modified water proof carbon paper (KB/WPCC) was used as an electrode material. The KB/WPCC surface was modified with 2-aminobenzoic acid and p-phenylenediamine, respectively, to face the positively charged electron-accepting site of BOD and the negatively charged electron-donating site of MBH to the electrode surface. A gas-diffusion system was employed for the electrodes to realize high-speed substrate supply. As result, great improvement in the current density of O2 reduction with BOD and H2 reduction with MBH were realized at negatively and postively charged surfaces, respectively. Gas diffusion system also suppressed the oxidative inactivation of MBH at high electrode potentials. Finally, based on the improved bioanode and biocathode, a dual gas-diffusion membrane- and mediatorless H2/air-breathing biofuel cell was constructed. The maximum power density reached 6.1 mW cm-2 (at 0.72 V), and the open circuit voltage was 1.12 V using 1 atm of H2 gas as a fuel at room temperature and under passive and quiescent conditions.

    The spatial resolution of a collimated CdZnTe Frisch collar detector was experimentally investigated for two different tungsten collimator designs using a {sup 198}Au gamma-ray source at 412 keV. A two-dimensional model for the detector-collimator-source geometry was developed and applied with some simplifying assumptions. The CdZnTe detector was fabricated from a single crystal using a copper shim as the Frisch collar. The detector fabrication process is briefly described. Pulse height spectra were collected from {sup 241}Am, {sup 198}Au and {sup 137}Cs using a 3.4x3.4x5.8 mm{sup 3} CdZnTe detector utilizing an insulated Frisch collar mounted inside a tungsten collimator. The resulting energy spectra are presented. Room-temperature energy resolution of 1.72% full-width at half-maximum (FWHM) was obtained for {sup 137}Cs at 662 keV without electronic correction. The two-dimensional model reasonably predicts the angular response of the CdZnTe detectors when inserted into two different collimators.

    This study concerns the oxidation mechanism of hydrogen sulfide and a fuel cell; acidic peroxide is used as the oxidant and basic hydrogen sulfide is the fuel. A solid state H2S/H2O2 stable fuel cell was produced at room temperature. A cell potential of 0.85 V was reached; this is quite remarkable in comparison to the H2S/O2 fuel cell potential of 0.85 V obtained at 850-1000 degree celsius. The hydrogen sulfide goes through an oxidation reaction in the alkaline fuel cell (H2S/H2O2 fuel cell) which opens up the possibility of using the cheaper nickel as a catalyst. As a result, the fuel cell becomes a potentially low cost technology. A further benefit from using H2S as the alkaline liquid H2S/H2O2 fuel cell, is that sulfide ions are oxidized at the anode, releasing electrons. Sulfur produced reacts with the other sulfide ions and forms disulfide and polysulfide ions in basic electrolytes (such as Black Sea water).

  7. Room Acoustics

    Science.gov (United States)

    Kuttruff, Heinrich; Mommertz, Eckard

    The traditional task of room acoustics is to create or formulate conditions which ensure the best possible propagation of sound in a room from a sound source to a listener. Thus, objects of room acoustics are in particular assembly halls of all kinds, such as auditoria and lecture halls, conference rooms, theaters, concert halls or churches. Already at this point, it has to be pointed out that these conditions essentially depend on the question if speech or music should be transmitted; in the first case, the criterion for transmission quality is good speech intelligibility, in the other case, however, the success of room-acoustical efforts depends on other factors that cannot be quantified that easily, not least it also depends on the hearing habits of the listeners. In any case, absolutely "good acoustics" of a room do not exist.

    The goal of this research is threefold: (1) use of the Skill-, Rule-, and Knowledge-based levels of cognitive control -- the SRK framework -- to develop an integrated information processing conceptual framework (for integration of workstation, job, and team design); (2) to evaluate the user interface component of this framework -- the Ecological display; and (3) to analyze the effect of operators` individual information processing behavior and decision styles on handling plant disturbances plus their performance on, and preference for, Traditional and Ecological user interfaces. A series of studies were conducted. In Part I, a computer simulation model and a mathematical model were developed. In Part II, an experiment was designed and conducted at the EBR-II plant of the Argonne National Laboratory-West in Idaho Falls, Idaho. It is concluded that: the integrated SRK-based information processing model for control room operations is superior to the conventional rule-based model; operators` individual decision styles and the combination of their styles play a significant role in effective handling of nuclear power plant disturbances; use of the Ecological interface results in significantly more accurate event diagnosis and recall of various plant parameters, faster response to plant transients, and higher ratings of subject preference; and operators` decision styles affect on both their performance and preference for the Ecological interface.

    Human errors can occur during the test and maintenance of steam generator, safety injection system and other various systems and devices in nuclear power plants (NPPs). Most of human errors can be improved by the human error prevention techniques such as self-check, peer-check, concurrent verification and etc. Another important technique is to share work information among main control room (MCR) operators and field workers. Various field service automation tools have been developed with recent information technology in many countries. APR1400 computerized procedure system (CPS) has been developed for the MCR operators of Shin-Kori 3 and 4 units. Especially, the concurrent verification support design is applied in the construction project of Shin-Hanul 1 and 2 CPS. It is expected that the proposed mobile CPS can enhance the reduction of human errors by supporting human error prevention techniques and information sharing. This paper describes the technical issues of the mobile CPS (mobile CPS) in the initial development stage. Based on the design of APR1400, CRI CPS has been developed and operated for SKN 3 and 4 HFE V and V and license test for the MCR operating staff. Therefore the mobile CPS will be developed by upgrading the CRI CPS with improved features.

    We used a large database of prospectively collected data on pediatric sedation/anesthesia outside the operating room provided by a wide range of pediatric specialists to delineate the nature and frequency of adverse events associated with propofol-based sedation/anesthesia care. Data were collected by the Pediatric Sedation Research Consortium, a collaborative group of institutions dedicated to improving sedation/anesthesia care for children internationally. Members prospectively enrolled consecutive patients receiving sedation or sedation/anesthesia for procedures. The primary inclusion criterion was the need for some form of sedation/anesthesia to perform a diagnostic or therapeutic procedure outside the operating room. There were no exclusion criteria. Data on demographics, primary illness, coexisting illness, procedure performed, medications used, procedure and recovery times, medication doses outcomes of anesthesia, airway interventions and adverse events were collected and reported using web-based data collection tool. For this study, we evaluated all instances where propofol was used as the primary drug in the sedation/anesthesia technique. Thirty-seven locations submitted data on 49,836 propofol sedation/anesthesia encounters during the study period from July 1, 2004 until September 1, 2007. There were no deaths. Cardiopulmonary resuscitation was required twice. Aspiration during sedation/anesthesia occurred four times. Less serious events were more common with O(2) desaturation below 90% for more than 30 s, occurring 154 times per 10,000 sedation/anesthesia administrations. Central apnea or airway obstruction occurred 575 times per 10,000 sedation/anesthesia administrations. Stridor, laryngospasm, excessive secretions, and vomiting had frequencies of 50, 96, 341, and 49 per 10,000 encounters, respectively. Unexpected admissions (increases in levels of care required) occurred at a rate of 7.1 per 10,000 encounters. In an unadjusted analysis, the rate of

    In this paper we discuss results from a recent high fidelity simulation of air traffic control operations with automated separation assurance in the presence of weather and time-constraints. We report findings from a human-in-the-loop study conducted in the Airspace Operations Laboratory (AOL) at the NASA Ames Research Center. During four afternoons in early 2010, fifteen active and recently retired air traffic controllers and supervisors controlled high levels of traffic in a highly automated environment during three-hour long scenarios, For each scenario, twelve air traffic controllers operated eight sector positions in two air traffic control areas and were supervised by three front line managers, Controllers worked one-hour shifts, were relieved by other controllers, took a 3D-minute break, and worked another one-hour shift. On average, twice today's traffic density was simulated with more than 2200 aircraft per traffic scenario. The scenarios were designed to create peaks and valleys in traffic density, growing and decaying convective weather areas, and expose controllers to heavy and light metering conditions. This design enabled an initial look at a broad spectrum of workload, challenge, boredom, and fatigue in an otherwise uncharted territory of future operations. In this paper we report human/system integration aspects, safety and efficiency results as well as airspace throughput, workload, and operational acceptability. We conclude that, with further refinements. air traffic control operations with ground-based automated separation assurance can be an effective and acceptable means to routinely provide very high traffic throughput in the en route airspace.

    Blood product transfusion is the most commonly performed hospital procedure. Intraoperative blood product utilization varies between institutions and anesthesiologists. In the United States in 2011, nearly 4 million plasma units were transfused. A retrospective analysis of intraoperative plasma ordering patterns and utilization (thawing and transfusing) was performed at a tertiary, academic hospital between January 2015 and March 2016. Over 15 months, 46,002 operative procedures were performed. In 1540 of them, plasma was thawed or transfused: 8297 plasma units were thawed and 3306 of those units were transfused. These 3306 plasma units were transfused in 749 cases with a median of 2 plasma units (interquartile range, 2-4) transfused. The percentage of average monthly procedures with plasma thawed and none transfused was 51.3% (confidence interval, 49.0%-53.6%). The cardiac surgery service requested the greatest number of plasma units to be thawed (2143) but only transfused 712 (33.2%) of them. Of all plasma units not transfused, 45% were generated by procedures with 1 to 4 units of plasma thawed; 95.7% of these units were thawed as even integers (ie, 2, 4). For operative procedures, far more plasma was thawed than was transfused and this practice occurred across surgical specialties and anesthesiologists. Considering the plasma that was not transfused, 45% occurred in procedures with 4 or fewer units of plasma requested suggesting these low-volume requests were a primary source of potential waste. Further studies are needed to examine associations between plasma utilization and clinical outcomes.

    Lower extremity acute compartment syndrome after gynecologic surgery in the lithotomy position is a rare, yet potentially devastating complication. A high level of suspicion is paramount for early recognition and mitigation of acute compartment syndrome originating from prolonged surgery in lithotomy position. A 23-year-old female, gravida 1, para 0, underwent a laparoscopic salpingectomy for a ruptured ectopic pregnancy. Surgical time was 90 min. Postoperatively, the patient developed acute compartment syndrome of both legs necessitating emergent bilateral four-compartment fasciotomies, with repeated returns to the operating room for 2nd look procedures and delayed wound closures. The patient regained full function within 3 months and returned to an unrestricted baseline activity level. Technical diligence in applying a lithotomy position is paramount for preventing postoperative lower extremity compartment syndrome. A high level of suspicion for this severe complication in conjunction with early recognition and immediate surgical management can mitigate long-term adverse sequelae and improve postoperative outcomes.

    Orthopedic and especially trauma surgeons' use of x-rays during operations vary extensively, especially in minimally invasive osteosynthesis procedures. Radiation hazards often are neglected. In this paper, a short overview of physical and biological effects of radiation are given. In addition, practical information about how to lower radiation exposure in the daily work in the operating room (OR) is given. The operating team is exposed mainly to scattered radiation. The radiation exposure is 10 times higher on the tube side than on the amplifier side. The distance between tube and surgeon must be as great as possible. The tube should be positioned under the OR table, and the distance between tube and patient should be as short as possible. The positioning of the C-arm device without radiation is important. The use of patient landmarks is used to position the C-arm over the region of interest, but the preoperative training of surgeons and team with virtual learning tools, e.g., virtX, is very effective in reducing radiation hazards.

    Time of operation has been reduced and accuracy of operation has been improved since C-arm, which offer real-time image of patient, was introduced in operation room. However, because of the contamination of patient, C-arm could not be used more appropriately. Therefore, this study is to know factors of controlling exposure dose, image quality and the exposed dose of health professional in operation room. Height of Wilson frame (bed for operation) was fixed at 130 cm. Then, Model 76-2 Phantom, which was set by assembling manual of Fluke Company, was set on the bed. Head/Spine Fluoroscopy AEC mode was set for exposure condition. According to detector size of C-arm, the absorbed dose per min was measured in the 7 steps OFD (cm) from 10 cm to 40 cm (10, 15, 20, 25, 30, 35, 40 cm). In each step of OFD, the absorbed dose per min of same diameter of collimation was measured. Moreover, using Nero MAX Model 8000, exposure dose per min was measured according to 3 step of distance from detector (20 cm, 60 cm, 100 cm). Finally, resolution was measured by CDRH Disc Phantom and magnification of each OFD was measured by aluminum stick bar. According to detector size of C-arm, difference of absorbed dose shows that the dose of 20 cm OFD is 1.750 times higher than the dose of 40 cm OFD. It means that the C-arm, which has smaller size of detector, shows the bigger difference of absorbed dose per min (p<0.05). In the difference of absorbed dose in the same step of OFD (from 20 cm to 40 cm), the absorbed dose of 9 inch detect or C-arm was 1.370 times higher than 12 inch' s (p<0.05). When OFD was set to 20 cm OFD, the absorbed dose of non-collimation case was approximately 0.816 times lower than the absorbed dose of collimation cases (p<0.05). When the distance was 20 cm from detector, exposed does includes first-ray and scatter-ray. When the distance was 60 cm and 100 cm from detector, exposed does includes just scatter-ray. So, there was the 2.200 times difference of absorbed

    This article presents the design, specificities and innovating features of the control room of the N4-type PWR. A brief description of control rooms of previous 900 MW and 1300 MW -type PWR allows us to assess the change. The design of the first control room dates back to 1972, at that time 2 considerations were taken into account: first the design has to be similar to that of control rooms for thermal plants because plant operators were satisfied with it and secondly the normal operating situation has to be privileged to the prejudice of accidental situations just as it was in a thermal plant. The turning point was the TMI accident that showed the weight of human factor in accidental situations in terms of pilot team, training, procedures and the ergonomics of the work station. The impact of TMI can be seen in the design of 1300 MW-type PWR. In the beginning of the eighties EDF decided to launch a study for a complete overhaul of the control room concept, the aim was to continue reducing the human factor risk and to provide a better quality of piloting the plant in any situation. The result is the control room of the N4-type PWR. Today the cumulated feedback experience of N4 control rooms represents more than 20 years over a wide range of situations from normal to incidental, a survey shows that the N4 design has fulfilled its aims.

    Full Text Available Objective: To study the utility of a commercially available small, portable ultra-high definition (HD camera (GoPro Hero 4 for intraoperative recording. Methods: A head mount was used to fix the camera on the operating surgeon′s head. Due care was taken to protect the patient′s identity. The recorded video was subsequently edited and used as a teaching tool. This retrospective, noncomparative study was conducted at three tertiary eye care centers. The surgeries recorded were ptosis correction, ectropion correction, dacryocystorhinostomy, angular dermoid excision, enucleation, blepharoplasty and lid tear repair surgery (one each. The recorded videos were reviewed, edited, and checked for clarity, resolution, and reproducibility. Results: The recorded videos were found to be high quality, which allowed for zooming and visualization of the surgical anatomy clearly. Minimal distortion is a drawback that can be effectively addressed during postproduction. The camera, owing to its lightweight and small size, can be mounted on the surgeon′s head, thus offering a unique surgeon point-of-view. In our experience, the results were of good quality and reproducible. Conclusions: A head-mounted ultra-HD video recording system is a cheap, high quality, and unobtrusive technique to record surgery and can be a useful teaching tool in external facial and ophthalmic plastic surgery.

    The objective of this study was to evaluate the operation of the portable X-ray machine in relation to examinations ordered by the Emergency Department at the University of Medicine and Dentistry of New Jersey, as well as to identify any bottlenecks hindering the performance of the aforementioned system. To do so, the activity of the portable X-ray was monitored in the period from 8 June 2004 to 24 June 2004, as well as from 6 July 2004 to 12 July 2004, yielding 11 days of data and 116 individual X-ray examinations. During observation times was noted for various checkpoints in the procedure. Using the data gathered, the average input, output, processing times, and variance were calculated. In turn, these values were used to calculate the response times for the Ordering Phase (5.502 min), traveling (2.483 min), Examination Phase (4.453 min), returning (3.855 min), Order Processing Phase (2.962 min), and the Development Phase (3.437 min). These phases were combined for a total of 22.721 min from the time the examination was placed to the time the X-ray films were uploaded to the PACS computer network. Based on these calculations, the Ordering Phase was determined to be the single largest bottleneck in the portable X-ray system. The Examination Phase also represented the second largest bottleneck for a combined total of 44% of the total response time.

    Purpose The aim of this study was to evaluate the operational impact of using preloaded intraocular lens (IOL) delivery systems compared with manually loaded IOL delivery processes during routine cataract surgeries. Methods Time and motion data, staff and surgery schedules, and cost accounting reports were collected across three sites located in the US, France, and Canada. Time and motion data were collected for manually loaded IOL processes and preloaded IOL delivery systems over four surgery days. Staff and surgery schedules and cost accounting reports were collected during the 2 months prior and after introduction of the preloaded IOL delivery system. Results The study included a total of 154 routine cataract surgeries across all three sites. Of these, 77 surgeries were performed using a preloaded IOL delivery system, and the remaining 77 surgeries were performed using a manual IOL delivery process. Across all three sites, use of the preloaded IOL delivery system significantly decreased mean total case time by 6.2%–12.0% (P<0.001 for data from Canada and the US and P<0.05 for data from France). Use of the preloaded delivery system also decreased surgeon lens time, surgeon delays, and eliminated lens touches during IOL preparation. Conclusion Compared to a manual IOL delivery process, use of a preloaded IOL delivery system for cataract surgery reduced total case time, total surgeon lens time, surgeon delays, and eliminated IOL touches. The time savings provided by the preloaded IOL delivery system provide an opportunity for sites to improve routine cataract surgery throughput without impacting surgeon or staff capacity.

  1. Principles of operating room organization.

    Watkins, W D

    1997-01-01

    The importance of the changing health care climate has triggered important changes in the management of high-cost components of acute care facilities. By integrating and better managing various elements of the surgical process, health care institutions are able to rationally trim costs while maintaining high-quality services. The leadership that physicians can provide is crucial to the success of this undertaking (1). The importance of the use of primary data related to patient throughput and related resources should be strongly emphasized, for only when such data are converted to INFORMATION of functional value can participating healthcare personnel be reasonably expected to anticipate and respond to varying clinical demands with ever-limited resources. Despite the claims of specific commercial vendors, no single product will likely be sufficient to significantly change the perioperative process to the degree or for the duration demanded by healthcare reform. The most effective approach to achieving safety, cost-effectiveness, and predictable process in the realm of Surgical Services will occur by appropriate application of the "best of breed" contributions of: (a) medical/patient safety practice/oversight; (b) information technology; (c) contemporary management; and (d) innovative and functional cost-accounting methodology. S "modified activity-based cost accounting method" can serve as the basis for acquiring true direct-cost information related to the perioperative process. The proposed overall management strategy emphasizes process and feedback, rather than specific product, and although imposing initial demands and change on the traditional hospital setting, can advance the strongest competitive position in perioperative services. This comprehensive approach comprises a functional basis for important bench-marking activities among multiple surgical services. An active, comparative process of this type is of paramount importance in emphasizing patient care and safety as the highest priority while changing the process and cost of perioperative care. Additionally, this approach objectively defines the surgical process in terms by which the impact of new treatments, drugs, devices and process changes can be assessed rationally.

    Highlights: • A digital device-based work verification and cooperation support system was developed. • Requirements were derived by interviewing field operators having experiences with mobile-based work support systems. • The usability of the proposed system was validated by conducting questionnaire surveys. • The proposed system will be useful if the manual or the set of guidelines is well constructed. - Abstract: Digital technologies have been applied in the nuclear field to check task results, monitor events and accidents, and transmit/receive data. The results of using digital devices have proven that these devices can provide high accuracy and convenience for workers, allowing them to obtain obvious positive effects by reducing their workloads. In this study, as one step forward, a digital device-based cooperation support system, the nuclear cooperation support and mobile documentation system (Nu-COSMOS), is proposed to support communication between main control room (MCR) operators and field workers by verifying field workers’ work results in nuclear power plants (NPPs). The proposed system consists of a mobile based information storage system to support field workers by providing various functions to make workers more trusted by MCR operators; also to improve the efficiency of meeting, and a large screen based information sharing system supports meetings by allowing both sides to share one medium. The usability of this system was estimated by interviewing field operators working in nuclear power plants and experts who have experience working as operators. A survey to estimate the usability of the suggested system and the suitability of the functions of the system for field working was conducted for 35 subjects who have experience in field works or with support system development-related research. The usability test was conducted using the system usability scale (SUS), which is widely used in industrial usability evaluation. Using questionnaires

    To evaluate a haptic-based simulator, MicroVisTouch™, as an assessment tool for capsulorhexis performance in cataract surgery. The study is a prospective, unmasked, nonrandomized dual academic institution study conducted at the Wilmer Eye Institute at Johns Hopkins Medical Center (Baltimore, MD, USA) and King Khaled Eye Specialist Hospital (Riyadh, Saudi Arabia). This prospective study evaluated capsulorhexis simulator performance in 78 ophthalmology residents in the US and Saudi Arabia in the first round of testing and 40 residents in a second round for follow-up. Four variables (circularity, accuracy, fluency, and overall) were tested by the simulator and graded on a 0-100 scale. Circularity (42%), accuracy (55%), and fluency (3%) were compiled to give an overall score. Capsulorhexis performance was retested in the original cohort 6 months after baseline assessment. Average scores in all measured metrics demonstrated statistically significant improvement (except for circularity, which trended toward improvement) after baseline assessment. A reduction in standard deviation and improvement in process capability indices over the 6-month period was also observed. An interval objective improvement in capsulorhexis skill on a haptic-enabled cataract surgery simulator was associated with intervening operating room experience. Further work investigating the role of formalized simulator training programs requiring independent simulator use must be studied to determine its usefulness as an evaluation tool.

    First-case tardiness is still a common source of frustration. In this study, a nationwide operating room (OR) Benchmark database was used to assess the effectiveness of interventions implemented to reduce tardiness and calculate its economic impact. Data from 8 University Medical Centers over 7 years were included: 190,295 elective inpatient first cases. Data were analyzed with SPSS statistics and multidisciplinary focus-group study meetings. Analysis of variance with contrast analysis measured the influence of interventions. Seven thousand ninety-four hours were lost annually to first-case tardiness, which has a considerable economic impact. Four University Medical Centers implemented interventions and effectuated a significant reduction in tardiness, eg providing feedbacks directly when ORs started too late, new agreements between OR and intensive care unit departments concerning "intensive care unit bed release" policy, and a shift in responsibilities regarding transport of patients to the OR. Nationwide benchmarking can be applied to identify and measure the effectiveness of interventions to reduce first-case tardiness in a university hospital OR environment. The implemented interventions in 4 centers were successful in significantly reducing first-case tardiness. Copyright © 2014 Elsevier Inc. All rights reserved.

    One of the declared objectives of surgical suite management in Germany is to increase operating room (OR) efficiency by reducing tardiness of first case of the day starts. We analyzed whether the introduction of OR management tools by German hospitals in response to increasing economic pressure was successful in achieving this objective. The OR management tools we considered were the appointment of an OR manager and the development and adoption of a surgical suite governance document (OR charter). We hypothesized that tardiness of first case starts was less in ORs that have adopted one or both of these tools. Using representative 2005 survey data from 107 German anesthesiology departments, we used a Tobit model to estimate the effect of the introduction of an OR manager or OR charter on tardiness of first case starts, while controlling for hospital size and surgical suite complexity. Adoption reduced tardiness of first case starts by at least 7 minutes (mean reduction 15 minutes, 95% confidence interval (CI): 7-22 minutes, P tardiness of first case starts figure prominently the objectives of surgical suite management in Germany. Our results suggest that the appointment of an OR manager or the adoption of an OR charter support this objective. For short-term decision making on the day of surgery, this reduction in tardiness may have economic implications, because it reduced overutilized OR time.

    Perimedullary arteriovenous fistula (AVF) shunts occur on the spinal cord surface and can be treated surgically or by endovascular embolization. In contrast, the nidus of an intramedullary arteriovenous malformation (AVM) is located in the spinal cord and is difficult to treat surgically or by endovascular techniques. The benefits of radiotherapy for treating intramedullary AVM have been published, but are anecdotal and consist largely of case reports. We present a case of combined cervical intramedullary AVM and perimedullary AVF which received surgical treatment within a hybrid operating room (OR) after 5 years of focus fractionated radiotherapy. A 37-year-old male presented with stepwise worsening myelopathy. Magnetic resonance imaging and spinal angiography revealed intramedullary AVM and perimedullary AVF at the C3 to C5 levels. In order to reduce nidus size and blood flow, we first performed focal fractionated radiotherapy. Five years later, the lesion volume was reduced. Following this, direct surgery was performed by an anterior approach using corpectomy in the hybrid OR. The spinal cord was monitored by motor-evoked potential throughout the surgery. Complete obliteration of the fistulous connection was confirmed by intraoperative indocyanine green video-angiography and intraoperative angiography, preserving the anterior spinal artery. We conclude that surgical treatment following focal fractionated radiotherapy may become one strategy for patients who are initially deemed ineligible for endovascular embolization and surgical treatment. Furthermore, the hybrid OR enables safe and precise treatment for spinal vascular disorders in the fields of endovascular treatment and neurosurgery. PMID:25367581

    Information technology, such as real-time location (RTL) systems using Radio Frequency IDentification (RFID) may contribute to overcome patient safety issues and high costs in healthcare. The aim of this work is to study if a RFID specific Participatory Design (PD) approach supports the design and the implementation of RTL systems in the Operating Room (OR). A RFID specific PD approach was used to design and implement two RFID based modules. The Device Module monitors the safety status of OR devices and the Patient Module tracks the patients' locations during their hospital stay. The PD principles 'multidisciplinary team', 'participation users (active involvement)' and 'early adopters' were used to include users from the RFID company, the university and the hospital. The design and implementation process consisted of two 'structured cycles' ('iterations'). The effectiveness of this approach was assessed by the acceptance in terms of level of use, continuity of the project and purchase. The Device Module included eight strategic and twelve tactical actions and the Patient Module included six strategic and twelve tactical actions. Both modules are now used on a daily basis and are purchased by the hospitals for continued use. The RFID specific PD approach was effective in guiding and supporting the design and implementation process of RFID technology in the OR. The multidisciplinary teams and their active participation provided insights in the social and the organizational context of the hospitals making it possible to better fit the technology to the hospitals' (future) needs.

    Because operating room (OR) management decisions with optimal choices are made with ubiquitous biases, decisions are improved with decision-support systems. We reviewed experimental social-psychology studies to explore what an OR leader can do when working with stakeholders lacking interest in learning the OR management science but expressing opinions about decisions, nonetheless. We considered shared information to include the rules-of-thumb (heuristics) that make intuitive sense and often seem "close enough" (e.g., staffing is planned based on the average workload). We considered unshared information to include the relevant mathematics (e.g., staffing calculations). Multiple studies have shown that group discussions focus more on shared than unshared information. Quality decisions are more likely when all group participants share knowledge (e.g., have taken a course in OR management science). Several biases in OR management are caused by humans' limited abilities to estimate tails of probability distributions in their heads. Groups are more susceptible to analogous biases than are educated individuals. Since optimal solutions are not demonstrable without groups sharing common language, only with education of most group members can a knowledgeable individual influence the group. The appropriate model of decision-making is autocratic, with information obtained from stakeholders. Although such decisions are good quality, the leaders often are disliked and the decisions considered unjust. In conclusion, leaders will find the most success if they do not bring OR management operational decisions to groups, but instead act autocratically while obtaining necessary information in 1:1 conversations. The only known route for the leader making such decisions to be considered likable and for the decisions to be considered fair is through colleagues and subordinates learning the management science.

    The aim of this study was to evaluate the use of a glucose meter with surgical patients under general anesthesia in the operating room. Glucose measurements were performed intraoperatively on 368 paired capillary and arterial whole blood samples using a Nova StatStrip (Nova Biomedical, USA) glucose meter and compared with 368 reference arterial whole blood glucose measurements by blood gas analyzer in 196 patients. Primary outcomes were median bias (meter minus reference), percentage of glucose meter samples meeting accuracy criteria for subcutaneous insulin dosing as defined by Parkes error grid analysis for type 1 diabetes mellitus, and accuracy criteria for intravenous insulin infusion as defined by Clinical and Laboratory Standards Institute guidelines. Time under anesthesia, patient position, diabetes status, and other variables were studied to determine whether any affected glucose meter bias. Median bias (interquartile range) was -4 mg/dl (-9 to 0 mg/dl), which did not differ from median arterial meter bias of -5 mg/dl (-9 to -1 mg/dl; P = 0.32). All of the capillary and arterial glucose meter values met acceptability criteria for subcutaneous insulin dosing, whereas only 89% (327 of 368) of capillary and 93% (344 of 368) arterial glucose meter values met accuracy criteria for intravenous insulin infusion. Time, patient position, and diabetes status were not associated with meter bias. Capillary and arterial blood glucose measured using the glucose meter are acceptable for intraoperative subcutaneous insulin dosing. Whole blood glucose on the meter did not meet accuracy guidelines established specifically for more intensive (e.g., intravenous insulin) glycemic control in the acute care environment.

    Technical progress in the surgical operating room (OR) increases constantly, facilitating the development of intelligent OR systems functioning as "safety backup" in the background of surgery. Precondition is comprehensive data retrieval to identify imminent risky situations and inaugurate adequate security mechanisms. Radio-frequency-identification (RFID) technology may have the potential to meet these demands. We set up a pilot study investigating feasibility and appliance reliability of a stationary RFID system for real-time surgical sponge monitoring (passive tagged sponges, position monitoring: mayo-stand/abdominal situs/waste bucket) and OR team tracking (active transponders, position monitoring: right/left side of OR table). In vitro: 20/20 sponges (100%) were detected on the mayo-stand and within the OR-phantom, however, real-time detection accuracy declined to 7/20 (33%) when the tags were moved simultaneously. All retained sponges were detected correctly. In vivo (animal): 7-10/10 sterilized sponges (70%-100%) were detected correctly within the abdominal cavity. OR-team: detection accuracy within the OR (surveillance antenna) and on both sides of the OR table (sector antenna) was 100%. Mean detection time for position change (left to right side and contrariwise) was 30-60 s. No transponder failure was noted. This is the first combined RFID system that has been developed for stationary use in the surgical OR. Preclinical evaluation revealed a reliable sponge tracking and correct detection of retained textiles (passive RFID) but also demonstrated feasibility of comprehensive data acquisition of team motion (active RFID). However, detection accuracy needs to be further improved before implementation into the surgical OR. Copyright © 2012 Elsevier Inc. All rights reserved.

    During MR-guided neurosurgical procedures performed in a combined 1.5 Tesla MR-operating room (MR-OR), we have successfully implemented and validated a functional MRI (fMRI) scheme for efficiently localizing eloquent functional areas and assessing their proximity to a lesion volume immediately prior to the craniotomy. The fMRI examination consists of a dynamical blood oxygenation level dependent (BOLD) MR imaging technique and a task paradigm that is designed to activate the brain area of interest. The functional imaging technique was based on gradient-echo (GE) echo-planar imaging (EPI) (TR/TE = 2000-3000/40-50 msec). The motor task paradigm involves a periodic movement task, such as alternating between thumb and the other four fingers as a finger-tapping task, while the language involved a covert repeat of a series of words given as a task stimulus. While patient is performing the task, a dynamical fMRI was performed concurrently covering the volume of interest every 2 or 3 sec. Also, we have used a temporal series averaging (TSA) method for correcting the background drift in the raw fMRI signal, and developed a scheme for presenting fMRI results to neurosurgeons in an intuitive 3-dimensional volume-rendered display format. By using the fMRI scheme, we have successfully performed sixteen fMRI examinations immediately prior to neurosurgery in the combined MR-OR on the same surgical table to localize various eloquent functional areas of interests. TSA was successful in reducing the background drift in the fMRI time course data, and the 3-dimensional volume-rendered display was proven effective in presenting the resulting brain activations to neurosurgeons. More importantly, in three representative cases (one biopsy and two tumor resections) presented, the information provided by fMRI have indeed contributed significantly in making the optimal surgical decisions prior to craniotomy. Intra-operative fMRI can be an indispensable tool for determining the location of a
