OBJECTIVE:: To evaluate the effect of an online training course containing video clips of central venous catheter insertions on compliance with sterile practice. DESIGN:: Prospective randomized controlled study. SETTING:: Admitting area of a university-based high-volume trauma center. SUBJECTS:: Surgical and emergency medicine residents rotating through the trauma services. INTERVENTIONS:: An online training course on recommended sterile practices during central venous catheter insertion was developed. The course contained short video clips from actual patient care demonstrating common noncompliant behaviors and breaks regarding recommended sterile practices. A 4-month study with a counterbalanced design compared residents trained by the video-based online training course (video group) with those trained with a paper version of the course (paper group). Residents who inserted central venous catheters but received neither the paper nor video training were used as a control group. Consecutive central venous catheter insertions from 12 noon to 12 midnight except Sundays were video recorded. MEASUREMENTS AND MAIN RESULTS:: Sterile-practice compliance was judged through video review by two surgeons blinded to the training status of the residents. Fifty residents inserted 73 elective central venous catheters (19, 31, and 23 by the video, paper, and control group operators, respectively) into 68 patients. Overall compliance with proper operator preparation, skin preparation, and draping was 49% (36 of 73 procedures). The training had no effect on selection of site and skin preparation agent. The video group was significantly more likely than the other two groups to fully comply with sterile practices (74% vs. 33%; odds ratio, 6.1; 95% confidence interval, 2.0-22.0). Even after we controlled for the number of years in residency training, specialty, number of central venous catheters inserted, and central venous catheter site chosen, the video group was more likely to comply with recommended sterile practices (p = .003). CONCLUSIONS:: An online training course, with short video clips of actual patient care demonstrating noncompliant behaviors, improved sterile-practice compliance for central venous catheter insertion. Paper handouts with equivalent content did not improve compliance. [ABSTRACT FROM AUTHOR]

Background: While direct oral anticoagulants (DOACs) have improved oral anticoagulation management, inappropriate prescribing remains prevalent and leads to adverse drug events. Antithrombotic stewardship programs seek to enhance DOAC prescribing but require scalable and sustainable strategies., Objective: We present a pilot, prescriber-level randomized controlled trial to assess the effectiveness of electronic health record (EHR)-based medication alerts in a large health system., Methods: The pilot assessed prescriber responses to alerts for initial DOAC prescription errors (apixaban and rivaroxaban). A user-centered, multistage design process informed alert development, emphasizing clear indication, appropriate dosing based on renal function, and drug-drug interactions. Alerts appeared whenever a DOAC was being prescribed in a way that did not follow package label instructions. Clinician responses measured acceptability, accuracy, feasibility, and utilization of the alerts., Results: The study ran from August 1, 2022, through April 30, 2023. Only 1 prescriber requested trial exclusion, demonstrating acceptability. The error rate for false alerts due to incomplete data was 6.6% (16/243). Two scenarios with alert design and/or execution errors occurred but were quickly identified and resolved, underlining the importance of a responsive quality assurance process in EHR-based interventions. Trial feasibility issues related to alert-data capture were identified and resolved. Trial feasibility was also assessed with balanced randomization of prescribers and the inclusion of various alerts across both medications. Assessing utilization, 34.2% (83/243) of the encounters (with 134 prescribers) led to a prescription change., Conclusions: The pilot implementation study demonstrated the acceptability, accuracy, feasibility, and estimates of the utilization of EHR-based medication alerts for DOAC prescriptions and successfully established just-in-time randomization of prescribing clinicians. This pilot study sets the stage for large-scale, randomized implementation evaluations of EHR-based alerts to improve medication safety., Trial Registration: ClinicalTrials.gov NCT05351749; https://clinicaltrials.gov/study/NCT05351749., (©Shawna N Smith, Michael S M Lanham, F Jacob Seagull, Morris Fabbri, Michael P Dorsch, Kathleen Jennings, Geoffrey Barnes.

Background: Direct oral anticoagulants (DOACs) have complex dosing regimens and are often incorrectly prescribed. We evaluated a nationwide DOAC population management dashboard rollout whose purpose includes pharmacist review and correction of off-label dosing prescriptions., Methods and Results: Using data from Veterans Health Affairs, we identified all patients prescribed DOACs for atrial fibrillation or venous thromboembolism between August 2015 and December 2019. Sites were grouped on the basis of the timing of moderate-high usage of the DOAC population management tool dashboard. Effectiveness was defined as the monthly rate of off-label DOAC prescribing and the rate of clinical adverse events (bleeding, composite of stroke or venous thromboembolism). Implementation was evaluated as the percentage of off-label DOAC prescriptions changed within 7 days. Among the 128 652 patients receiving DOAC therapy at 123 centers, between 6.9% and 8.6% had off-label DOAC prescriptions. Adoption of the DOAC population management tool dashboard before July 2018 was associated with a decline in off-label dosing prescriptions (8.7%-7.6%). Only 1 group demonstrated a significant reduction in monthly rates of bleeding following implementation. All sites experienced a reduction in the composite of venous thromboembolism or stroke following dashboard adoption. There was no difference in the implementation outcome of DOAC prescription change within 7 days in any of the adoption groups., Conclusions: Early adoption of the DOAC population management tool dashboard was associated with decreased rates of off-label DOAC dosing prescription and reduced bleeding. Following adoption of the DOAC population management tool dashboard, all sites experienced reductions in venous thromboembolism and stroke events.

Background: Direct oral anticoagulant (DOAC) medications are frequently associated with inappropriate prescribing and adverse events. To improve the safe use of DOACs, health systems are implementing population health tools within their electronic health record (EHR). While EHR informatics tools can help increase awareness of inappropriate prescribing of medications, a lack of empowerment (or insufficient empowerment) of nonphysicians to implement change is a key barrier., Objective: This study examined how the individual authority of clinical pharmacists and anticoagulation nurses is impacted by and changes the implementation success of an EHR DOAC Dashboard for safe DOAC medication prescribing., Methods: We conducted semistructured interviews with pharmacists and nurses following the implementation of the EHR DOAC Dashboard at 3 clinical sites. Interview transcripts were coded according to the key determinants of implementation success. The intersections between individual clinician authority and other determinants were examined to identify themes., Results: A high level of individual clinician authority was associated with high levels of key facilitators for effective use of the DOAC Dashboard (communication, staffing and work schedule, job satisfaction, and EHR integration). Conversely, a lack of individual authority was often associated with key barriers to effective DOAC Dashboard use. Positive individual authority was sometimes present with a negative example of another determinant, but no evidence was found of individual authority co-occurring with a positive instance of another determinant., Conclusions: Increased individual clinician authority is a necessary antecedent to the effective implementation of an EHR DOAC Population Management Dashboard and positively affects other aspects of implementation., International Registered Report Identifier (irrid): RR2-10.1186/s13012-020-01044-5., (©Allison Ranusch, Ying-Jen Lin, Michael P Dorsch, Arthur L Allen, Patrick Spoutz, F Jacob Seagull, Jeremy B Sussman, Geoffrey D Barnes.

Background: Available resources within an organization can determine the implementation success of an intervention. However, few studies have investigated how the required resources change over the phases of implementation. Using stakeholder interviews, we examined the changes in and interactions between available resources and implementation climate in the implementation and sustainment phases of a national implementation effort for a population health tool., Methods: We conducted a secondary analysis of the interviews with 20 anticoagulation professionals at 17 clinical sites in the Veterans Health Administration health system about their experiences with a population health dashboard for anticoagulant management. Interview transcripts were coded using constructs from the Consolidated Framework for Implementation Research (CFIR) and according to the phase of implementation (pre-implementation, implementation, and sustainment) as defined by the VA Quality Enhancement Research Initiative (QUERI) Roadmap. We analyzed the factors that may determine successful implementation by examining the co-occurrence patterns between available resources and implementation climate across different implementation phases. To illustrate the variations in these determinants across phases, we aggregated and scored coded statements using a previously published CFIR scoring system (- 2 to + 2). Key relationships between available resources and implementation climate were identified and summarized using thematic analysis., Results: The resources necessary to support the successful implementation of an intervention are not static; both the quantity and types of resources shift based on the phases of the intervention. Furthermore, increased resource availability does not guarantee the sustainment of intervention success. Users need different types of support beyond the technical aspects of an intervention, and this support varies over time. Specifically, available resources in the form of technological support and social/emotional support help users establish trust in a new technological-based intervention during the implementation phase. Resources that foster and maintain collaboration between users and other stakeholders help them stay motivated during sustainment., Conclusions: Our findings highlight the dynamic nature of available resources and their impacts on the implementation climate across different phases of implementation. A better understanding of the dynamics of available resources over time from the users' perspectives will allow the adaptation of resources to better meet the needs of the intervention stakeholders., (© 2023.

Background: Direct oral anticoagulant medications are commonly used to treat or prevent thrombotic conditions, such as pulmonary embolism, deep vein thrombosis, and atrial fibrillation. However, up to 10-15% of patients receiving these medications get unsafe doses based on a patient's kidney or liver function, potential interactions with other medications, and indication for taking the medication. Alert systems may be beneficial for improving evidence-based prescribing, but can be burdensome and are not currently able to provide monitoring after the initial prescription is written., Methods/design: This study will improve upon existing alert systems by testing novel medication alerts that encourage collaboration between prescribers (e.g., physicians, nurse practitioners, physician assistants) and expert pharmacists working in anticoagulation clinics. The study will also improve upon the existing alert system by incorporating dynamic long-term monitoring of patient needs and encouraging collaboration between prescribers and expert pharmacists working in anticoagulation clinics. Incorporating state-of-the-art user-centered design principles, prescribing healthcare providers will be randomized to different types of electronic health record medication alerts when a patient has an unsafe anticoagulant prescription. We will identify which alerts are most effective at encouraging evidence-based prescribing and will test moderators to tailor alert delivery to when it is most beneficial. The aims of the project are to (1) determine the effect of notifications targeting existing inappropriate DOAC prescriptions; (2) examine the effect of alerts on newly prescribed inappropriate DOACs; and (3) examine changes in the magnitude of effects over time for both the new prescription alerts and existing prescription notifications for inappropriate DOACs over the 18-month study period., Discussion: Findings from this project will establish a framework for implementing prescriber-pharmacist collaboration for high-risk medications, including anticoagulants. If effectively implemented at the more than 3000 anticoagulation clinics that exist nationally, hundreds of thousands of patients taking direct oral anticoagulants stand to benefit from safer, evidence-based healthcare., Trials Registration: NCT05351749., (© 2023. The Author(s).)

Background: Direct oral anticoagulants are first-line therapy for common thrombotic conditions, including atrial fibrillation and venous thromboembolism. Despite their strong efficacy and safety profile, evidence-based prescribing can be challenging given differences in dosing based on indication, renal function, and drug-drug interactions. The Veterans Health Affairs developed and implemented a population management dashboard to support pharmacist review of anticoagulant prescribing. The dashboard includes information about direct oral anticoagulants and dose prescribed, renal function, age, and weight, potential interacting medications, and the need for direct oral anticoagulant medication refills. It is a stand-alone system., Methods: Using login data from the dashboard, nationwide implementation was evaluated using elements from the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework., Results: Between August 2016 and June 2020, 150/164 sites within the Veterans Health Affairs system used the dashboard, averaging 1875 patients per site. The dashboard was made available to sites on a staggered basis. Moderate or high adoption, defined as at least one login on at least 2 separate days per month, began slowly with 3/5 sites in the pilot phase but rapidly grew to 142/150 (94.7%) sites by June 2020. The average number of unique users per site increased from 2.4 to 7.5 over the study period. Moderate to high adoption of the dashboard's use was maintained for > 6 months in 126/150 (84.0%) sites by the end of the study period., Conclusions: There was rapid and sustained implementation and adoption of a population health dashboard for evidence-based anticoagulant prescribing across the national United States Veterans Health Administration health system. The impact of this tool on clinical outcomes and strategies to replicate this care model in other health systems will be important for broad dissemination and uptake.

Background: Direct oral anticoagulants (DOACs) are widely used medications with an unacceptably high rate of prescription errors and are a leading cause of adverse drug events. Clinical decision support, including medication alerts, can be an effective implementation strategy to reduce prescription errors, but quality is often inconsistent. User-centered design (UCD) approaches can improve the effectiveness of alerts., Objectives: To design effective DOAC prescription alerts through UCD and develop a set of generalizable design recommendations., Methods: This study used an iterative UCD process with practicing clinicians. In three rapid iterative design and assessment stages, prototype alert designs were created and refined using a test electronic health record (EHR) environment and simulated patients. We identified key emergent themes across all user observations and interviews. The themes and final designs were used to derive a set of design guidelines., Results: Our UCD sample comprised 13 prescribers, including advanced practice providers, physicians in training, primary care physicians, and cardiologists. The resulting alert designs embody our design recommendations, which include establishing intended indication, clarifying dosing by renal function, tailoring alert language in drug interactions, facilitating trust in alerts, and minimizing interaction overhead., Conclusions: Through a robust UCD process, we have identified key recommendations for implementing medication alerts aimed at improving evidence-based DOAC prescribing. These recommendations may be applicable to the implementation of DOAC alerts in any EHR systems., (© 2022 The Authors.

In caring for patients with sepsis, the current structure of electronic health record systems allows clinical providers access to raw patient data without imputation of its significance. There are a wide range of sepsis alerts in clinical care that act as clinical decision support tools to assist in early recognition of sepsis; however, there are serious shortcomings in existing health information technology for alerting providers in a meaningful way. Little work has been done to evaluate and assess existing alerts using implementation and process outcomes associated with health information technology displays, specifically evaluating clinician preference and performance. We developed graphical model displays of two popular sepsis scoring systems, quick Sepsis Related Organ Failure Assessment and Predisposition, Infection, Response, Organ Failure , using human factors principles grounded in user-centered and interaction design. Models will be evaluated in a larger research effort to optimize alert design to improve the collective awareness of high-risk populations and develop a relevant point-of-care clinical decision support system for sepsis.

Objectives: Febrile neutropenic pediatric patients are at heightened risk for serious bacterial infections, and rapid antibiotic administration (in <60 minutes) improves survival. Our objectives were to reduce the time-to-antibiotic (TTA) administration and to evaluate the effect of overall emergency department (ED) busyness on TTA., Methods: This study was a quality improvement initiative with retrospective chart review to reduce TTA in febrile children with underlying diagnosis of cancer or hematologic immunodeficiency who visited the pediatric ED. A multidisciplinary clinical practice guideline (CPG) was implemented to improve TTA. The CPG's main focus was delivery of antibiotics before availability of laboratory data. We collected data on TTA during baseline and intervention periods. Concurrent patient arrivals to the ED per hour served as a proxy of busyness. Time to antibiotic was compared with the number of concurrent arrivals per hour. Analyses included scatter plot and regression analysis., Results: There were 253 visits from October 1, 2010 to March 30, 2012. Median TTA administration dropped from 207 to 89 minutes (P < 0.001). Eight months after completing all intervention periods, the median had dropped again to 44 minutes with 70% of patients receiving antibiotics within 60 minutes of ED arrival. There was no correlation between concurrent patient arrivals and TTA administration during the historical or intervention periods., Conclusions: Implementation of a CPG and process improvements significantly reduced median TTA administration. Total patient arrivals per hour as a proxy of ED crowding did not affect TTA administration. Our data suggest that positive improvements in clinical care can be successful despite fluctuations in ED patient volume.

Background: Currently there is no reliable, standardized mechanism to support health care professionals during the evaluation of and procurement processes for simulators. A tool founded on best practices could facilitate simulator purchase processes., Methods: In a 3-phase process, we identified top factors considered during the simulator purchase process through expert consensus (n = 127), created the Simulator Value Index (SVI) tool, evaluated targeted validity evidence, and evaluated the practical value of this SVI. A web-based survey was sent to simulation professionals. Participants (n = 79) used the SVI and provided feedback. We evaluated the practical value of 4 tool variations by calculating their sensitivity to predict a preferred simulator., Results: Seventeen top factors were identified and ranked. The top 2 were technical stability/reliability of the simulator and customer service, with no practical differences in rank across institution or stakeholder role. Full SVI variations predicted successfully the preferred simulator with good (87%) sensitivity, whereas the sensitivity of variations in cost and customer service and cost and technical stability decreased (≤54%). The majority (73%) of participants agreed that the SVI was helpful at guiding simulator purchase decisions, and 88% agreed the SVI tool would help facilitate discussion with peers and leadership., Conclusion: Our findings indicate the SVI supports the process of simulator purchase using a standardized framework. Sensitivity of the tool improved when factors extend beyond traditionally targeted factors. We propose the tool will facilitate discussion amongst simulation professionals dealing with simulation, provide essential information for finance and procurement professionals, and improve the long-term value of simulation solutions. Limitations and application of the tool are discussed., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: As resident "index" procedures change in volume due to advances in technology or reliance on simulation, it may be difficult to ensure trainees meet case requirements. Training programs are in need of metrics to determine how many residents their institutional volume can support., Objective: As a case study of how such metrics can be applied, we evaluated a case distribution simulation model to examine program-level mediastinoscopy and endobronchial ultrasound (EBUS) volumes needed to train thoracic surgery residents., Methods: A computer model was created to simulate case distribution based on annual case volume, number of trainees, and rotation length. Single institutional case volume data (2011-2013) were applied, and 10 000 simulation years were run to predict the likelihood (95% confidence interval) of all residents (4 trainees) achieving board requirements for operative volume during a 2-year program., Results: The mean annual mediastinoscopy volume was 43. In a simulation of pre-2012 board requirements (thoracic pathway, 25; cardiac pathway, 10), there was a 6% probability of all 4 residents meeting requirements. Under post-2012 requirements (thoracic, 15; cardiac, 10), however, the likelihood increased to 88%. When EBUS volume (mean 19 cases per year) was concurrently evaluated in the post-2012 era (thoracic, 10; cardiac, 0), the likelihood of all 4 residents meeting case requirements was only 23%., Conclusions: This model provides a metric to predict the probability of residents meeting case requirements in an era of changing volume by accounting for unpredictable and inequitable case distribution. It could be applied across operations, procedures, or disease diagnoses and may be particularly useful in developing resident curricula and schedules., Competing Interests: The authors declare they have no competing interests.

Objective: To evaluate the implementation of a new clinical protocol utilizing on-unit simulation for team training., Methods: A prospective observational study was performed at the obstetrics unit of Von Voightlander Women's Hospital, Michigan, USA, between October 1, 2012 to April 30, 2013. All members of the labor and delivery team were eligible for participation. Traditional education methods and in-situ multi-disciplinary simulations were used to educate labor and delivery staff. Following each simulation, participants responded to a survey regarding their experience. To evaluate the effect of the interventions, paging content was analyzed for mandated elements and adherence to operating room entry-time tracking was examined., Results: In total, 51 unique individuals participated in 12 simulations during a 6-month period. Simulation was perceived as a valuable activity and paging content improved. Following the intervention, the inclusion of a goal time for reaching the operation room increased from 7% to 61% of pages and the proportion of patients entering to operating room within 10 minutes of the stated goal increased from 67% to 85%., Conclusion: The training program was well received, and the accuracy of the communication and the goal set for reaching the operating room improved., (Copyright © 2016 International Federation of Gynecology and Obstetrics.

Background: Continuous quality improvement (CQI) has been successfully applied in business and engineering for over 60 years. While using CQI techniques within nephrology has received increased attention, little is known about where, and with what measure of success, CQI can be attributed to improving outcomes within nephrology care. This is particularly important as payors' focus on value-based healthcare and reimbursement is tied to achieving quality improvement thresholds. We conducted a systematic review of CQI applications in nephrology., Methods: Studies were identified from PubMed, MEDLINE, Scopus, Web of Science, CINAHL, Google Scholar, ProQuest Dissertation Abstracts and sources of grey literature (i.e., available in print/electronic format but not controlled by commercial publishers) between January 1, 2004 and October 13, 2014. We developed a systematic evaluation protocol and pre-defined criteria for review. All citations were reviewed by two reviewers with disagreements resolved by consensus., Results: We initially identified 468 publications; 40 were excluded as duplicates or not available/not in English. An additional 352 did not meet criteria for full review due to: 1. Not meeting criteria for inclusion = 196 (e.g., reviews, news articles, editorials) 2. Not nephrology-specific = 153, 3. Only available as abstracts = 3. Of 76 publications meeting criteria for full review, the majority [45 (61%)] focused on ESRD care. 74% explicitly stated use of specific CQI tools in their methods. The highest number of publications in a given year occurred in 2011 with 12 (16%) articles. 89% of studies were found in biomedical and allied health journals and most studies were performed in North America (52%). Only one was randomized and controlled although not blinded., Conclusions: Despite calls for healthcare reform and funding to inspire innovative research, we found few high quality studies either rigorously evaluating the use of CQI in nephrology or reporting best practices. More rigorous research is needed to assess the mechanisms and attributes by which CQI impacts outcomes before there is further promotion of its use for improvement and reimbursement purposes.

Background: Certain operative cases occur unpredictably and/or have long operative times, creating a conflict between Accreditation Council for Graduate Medical Education (ACGME) rules and adequate training experience., Methods: A ProModel-based simulation was developed based on historical data. Probabilistic distributions of operative time calculated and combined with an ACGME compliant call schedule., Results: For the advanced surgical cases modeled (cardiothoracic transplants), 80-hour violations were 6.07% and the minimum number of days off was violated 22.50%. There was a 36% chance of failure to fulfill any (either heart or lung) minimum case requirement despite adequate volume., Conclusions: The variable nature of emergency cases inevitably leads to work hour violations under ACGME regulations. Unpredictable cases mandate higher operative volume to ensure achievement of adequate caseloads. Publically available simulation technology provides a valuable avenue to identify adequacy of case volumes for trainees in both the elective and emergency setting., (Copyright © 2015 Elsevier Inc.

Background: The educational resources available to general surgery residents preparing for complex thoracic surgeries vary greatly in content and target audience. We hypothesized that the preparatory resources could be improved in both efficiency of use and targeting., Methods: A formal needs analysis was performed to determine residents' knowledge gaps and desired format and/or content of an educational tool while preparing for their first lung resections. The results of the needs assessment then guided the creation of a 20-min video tool. The video was evaluated by a focus group of experts for appropriateness to the target audience, ease of use, and relevance., Results: The needs assessment illustrated that residents feel there is a paucity of appropriate resources available to them while preparing for the lung resection procedure; 82% of respondents felt that easy-to-use and concise resources on the lobectomy procedure were either "not at all" or "somewhat" accessible. Residents reported that video was their preferred format for a learning tool overall and identified a broad spectrum of most challenging procedural aspects. These results were used to guide the creation of a 20-min video tool. A focus group validated the efficacy and appropriateness of the video., Conclusions: Targeted and efficient tools for residents preparing for complex subspecialty procedures are needed and valued. These results clearly encourage further work in the creation of focused educational tools for surgical residents, especially in the format of short video overviews., (Copyright © 2015 Elsevier Inc.

Rationale and Objectives: To compare resident workload from Emergency Department (ED) studies before and after the implementation of a required 1-hour report turnaround time (TAT) and to assess resident and faculty perception of TAT on resident education., Materials and Methods: Resident study volume will be compared for 3 years before and 1 year after the implementation of a required 1-hour TAT. Changes to resident workload will be compared among the different radiology divisions (body, muscuolskeletal (MSK), chest, and neuro), as well as during different shifts (daytime and overnight). Residents and faculty at two Midwest institutions, both of which have a required report TAT, will be invited to participate in an online survey to query the perceived effect on resident education by implementation of this requirement. A P < .05 was considered statistically significant., Results: A significant decrease in resident involvement in ED studies was noted in the MSK, chest, and neuro sections with average involvement of the 3 years before the 1-hour TAT of 89%, 88%, and 82%, respectively, which decreased to 66%, 68%, and 51% after the 1-hour TAT requirement (P < .05). The resident involvement in ED studies only mildly decreased in the body section from an average before the 1-hour TAT of 87% to 80% after the 1-hour TAT requirement (P < .1). There was an overall significant decrease in resident ED study involvement during the daytime (P = .01) but not after hours during resident call (P = .1). Seventy percent of residents (43 of 61) and 55% of faculty (63 of 114) responded to our surveys. Overall, residents felt their education from ED studies during the daytime and overnight were good. However, residents who were present both before and after the implementation of a required TAT felt their education had been significantly negatively affected. Faculty surveyed thought that the required TAT negatively affected their ability to teach and decreased the quality of resident education., Conclusions: Residents are exposed to fewer ED studies after the implementation of a required 1-hour TAT. Overall, the current residents do not feel this decreased exposure to Emergency room studies affects their education. However, residents in training before and after this requirement feel their education has been significantly affected. Faculty perceives that the required TAT negatively affects their ability to teach, as well as the quality of resident education., (Copyright © 2015 AUR. Published by Elsevier Inc.

In healthcare, the sustained presence of hierarchy between team members has been cited as a common contributor to communication breakdowns. Hierarchy serves to accentuate either actual or perceived chains of command, which may result in team members failing to challenge decisions made by leaders, despite concerns about adverse patient outcomes. While other tools suggest improved communication, none focus specifically on communication skills for team followers, nor do they provide techniques to immediately challenge authority and escalate assertiveness at a given moment in real time. This article presents data that show one such strategy, called the Effective Followership Algorithm, offering statistically significant improvements in team communication across the professional continuum from students and residents to experienced clinicians., (© 2015 American Society for Healthcare Risk Management of the American Hospital Association.)

Background: Simulation-based education (SBE) has advanced greatly in surgery the past decade, partly through development of validated performance measurement. Standard measures are commonly used to evaluate performance (eg, Objective Structured Assessment of Technical Skills, Fundamentals of Laparoscopic Surgery, Global Operative Assessment of Laparoscopic Skills [GOALS]). However, subjective measures are necessary for ensuring content validity during evaluation of novel simulations or simulators. Although commonly assessed, there are no standardized instruments for such surveys of participants. This lack of standardization limits the ability to compare simulations and/or simulators. We performed a focused literature review to assess current uses of subjective measures, and develop a template for a standardized assessment tool., Methods: A representative sample of recently collected subjective measures was generated through a focused literature review of the journals Surgery, Journal of Surgical Education, and Journal of the American College of Surgeons (January 2008-November 2012) using the key words "surgical" and "simulation.", Results: Of the 137 articles relevant to development and/or evaluation of surgical skills curricula or simulators, 19 (12%) reported subjective measures from participants. Ten domains were identified, including Self-efficacy/Confidence/Comfort (11, 57%), Model quality/characteristics (7, 37%), Educational/Program value (6, 32%), Previous experience with procedure/simulation (5, 26%) Relevance to practice (3, 16%), Quality- trainer feedback (3, 16%), Quality-experience (2, 11%), Attitude toward specific aspects (2, 11%), Satisfaction/Enjoyability (2, 11%), Ability to perform relevant task(s) (2, 11%). Response options varied and included 4-, 5-, and 10-point rating scales, Visual Analog Scales, and open written responses., Conclusion: These results suggest that simulation experiences are not currently assessed in a systematic manner. However, analysis of the literature suggests that the full range of subjective measures commonly used for subjective assessment could be addressed by a unified assessment instrument. To this end, the Michigan Standard Simulation Experience Scale (MiSSES) template has been developed and is available on-line. Such a tool would provide practitioners a freely available resource used to measure performance and preferences in SBE., (Copyright © 2014 Mosby, Inc. All rights reserved.)

Rationale and Objectives: Despite increasing radiology coverage, nonradiology residents continue to preliminarily interpret basic radiologic studies independently, yet their ability to do so accurately is not routinely assessed., Materials and Methods: An online test of basic radiologic image interpretation was developed through an iterative process. Educational objectives were established, then questions and images were gathered to create an assessment. The test was administered online to first-year interns (postgraduate year [PGY] 1) from 14 different specialties, as well as a sample of third- and fourth-year radiology residents (PGY3/R2 and PGY4/R3)., Results: Over a 2-year period, 368 residents were assessed, including PGY1 (n = 349), PGY3/R2 (n = 14), and PGY4/R3 (n = 5) residents. Overall, the test discriminated effectively between interns (average score = 66%) and advanced residents (R2 = 86%, R3 = 89%; P < .05). Item analysis indicated discrimination indices ranging from -0.72 to 48.3 (mean = 3.12, median 0.58) for individual questions, including four questions with negative discrimination indices. After removal of the negatively indexed questions, the overall predictive value of the instrument persisted and discrimination indices increased for all but one of the remaining questions (range 0.027-70.8, mean 5.76, median 0.94)., Conclusions: Validation of an initial iteration of an assessment of basic image-interpretation skills led to revisions that improved the test. The results offer a specific test of radiologic reading skills with validation evidence for residents. More generally, results demonstrate a principled approach to test development., (Copyright © 2014 AUR. Published by Elsevier Inc. All rights reserved.)

Human factors (HF) is a discipline often drawn upon when there is a need to train people to perform complex, high-stakes tasks and effectively assess their performance. Complex tasks often present unique challenges for training and assessment. HF has developed specialized techniques that have been effective in overcoming several of these challenges in work settings such as aviation, process control, and the military. Many HF techniques could be applied to simulation in continuing medical education to enhance effectiveness of simulation and training, yet these techniques are not widely known by medical educators. Three HF techniques are described that could benefit health care simulation in areas of training techniques, assessment, and task design: (1) bandwidth feedback techniques for designing better feedback and task guidance, (2) dual-task assessment techniques that can differentiate levels of expertise in tasks where performance is essentially perfect, and (3) task abstraction techniques for developing task-relevant fidelity for simulations. Examples of each technique are given from work settings in which these principles have been applied successfully. Application of these principles to medical simulation and medical education is discussed. Adapting these techniques to health care could improve training in medical education., (Copyright © 2012 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on CME, Association for Hospital Medical Education.)

A surgeon's work environment and working conditions are often harsher than those of an industrial worker. Accepted principles and regulations of ergonomics in manufacturing are largely ignored or absent in the medical/surgical domain. Examples include poor surgical tool handle design, awkward and stressful surgical postures, and prolonged standing without breaks and without a foot mat. In these and other areas, there are documented "best practices" for industrial hygiene and ergonomics that are not yet widely accepted for surgery. There is support in the literature for innovations in surgical ergonomics, yet adoption is not widespread. In the absence of these ergonomic principles, surgical repetitive strain injuries in minimally invasive surgery are reaching epidemic levels. As ergonomists, it falls upon us to understand why current solutions have not been widely adopted within this domain, and to derive solutions to the unique challenges of surgery.

Online social networking is an immature, but rapidly evolving industry of web-based technologies that allow individuals to develop online relationships. News stories populate the headlines about various websites which can facilitate patient and doctor interaction. There remain questions about protecting patient confidentiality and defining etiquette in order to preserve the doctor/patient relationship and protect physicians. How much social networking-based communication or other forms of E-communication is effective? What are the potential benefits and pitfalls of this form of communication? Physicians are exploring how social networking might provide a forum for interacting with their patients, and advance collaborative patient care. Several organizations and institutions have set forth policies to address these questions and more. Though still in its infancy, this form of media has the power to revolutionize the way physicians interact with their patients and fellow health care workers. In the end, physicians must ask what value is added by engaging patients or other health care providers in a social networking format. Social networks may flourish in health care as a means of distributing information to patients or serve mainly as support groups among patients. Physicians must tread a narrow path to bring value to interactions in these networks while limiting their exposure to unwanted liability.

Background: Laparoscopic incisional hernia repair (LIHR) is a common procedure requiring advanced laparoscopic skills. This study aimed to develop a procedure-specific tool to assess the performance of LIHR and to evaluate its reliability and validity., Methods: The Global Operative Assessment of Laparoscopic Skills-Incisional Hernia (GOALS-IH) is a 7-item global rating scale developed by experts to evaluate the steps of LIHR (placement of trocars, adhesiolysis, estimation of mesh size and shape, mesh orientation and positioning, mesh fixation, knowledge and autonomy in use of instruments, overall competence), each rated on a 5-point Likert scale. During LIHR, 13 attending surgeons and fellows experienced in minimally invasive surgery (MIS) and 19 novice surgeons (postgraduate years [PGYs], 3-5) were evaluated at four teaching hospitals by the attending surgeon, a trained observer, and self-assessment using GOALS-IH, and by a previously validated 5-item general laparoscopic rating scale (GOALS). Interrater reliability was assessed by intraclass correlation (ICC), and internal consistency of rating items was assessed by Cronbach's alpha. Known-groups construct validity was assessed by using the t-test and by correlating of the number of self-reported LIHR cases with the total score. Concurrent validity was assessed by correlating the GOALS-IH score with the GOALS general rating scale. Data are presented as mean and 95% confidence interval (CI)., Results: Interrater reliability for the total GOALS-IH score was 0.79 (95% CI, 0.60-0.89) between observers and attending surgeons, 0.81 (95% CI, 0.58-0.92) between participants and attending surgeons, and 0.89 (95% CI, 0.76-0.96) between participants and observers. Internal consistency was high (Cronbach's alpha, 0.93). Experienced surgeons performed significantly better than novices as assessed by GOALS-IH (31; 95% CI, 29-33 vs. 21; 95% CI, 19-24; p < 0.01). Very good correlation was found between GOALS-IH and previous LIHR experience (r = 0.82; p < 0.01) and strong correlation between GOALS-IH and generic GOALS total scores (r = 0.90; p < 0.01)., Conclusion: Surgical performance during clinical LIHR can be assessed reliably using GOALS-IH. Results can be used to provide formative feedback to the surgeon and to identify steps of the operation that would benefit from specific educational interventions.

Background: This study compares surgical techniques and surgeon's standing position during laparoscopic cholecystectomy (LC), investigating each with respect to surgeons' learning, performance, and ergonomics. Little homogeneity exists in LC performance and training. Variations in standing position (side-standing technique vs. between-standing technique) and hand technique (one-handed vs. two-handed) exist., Methods: Thirty-two LC procedures performed on a virtual reality simulator were video-recorded and analyzed. Each subject performed four different procedures: one-handed/side-standing, one-handed/between-standing, two-handed/side-standing, and two-handed/between-standing. Physical ergonomics were evaluated using Rapid Upper Limb Assessment (RULA). Mental workload assessment was acquired with the National Aeronautics and Space Administration-Task Load Index (NASA-TLX). Virtual reality (VR) simulator-generated performance evaluation and a subjective survey were analyzed., Results: RULA scores were consistently lower (indicating better ergonomics) for the between-standing technique and higher (indicating worse ergonomics) for the side-standing technique, regardless of whether one- or two-handed. Anatomical scores overall showed side-standing to have a detrimental effect on the upper arms and trunk. The NASA-TLX showed significant association between the side-standing position and high physical demand, effort, and frustration (p<0.05). The two-handed technique in the side-standing position required more effort than the one-handed (p<0.05). No difference in operative time or complication rate was demonstrated among the four procedures. The two-handed/between-standing method was chosen as the best procedure to teach and standardize., Conclusions: Laparoscopic cholecystectomy poses a risk of physical injury to the surgeon. As LC is currently commonly performed in the United States, the left side-standing position may lead to increased physical demand and effort, resulting in ergonomically unsound conditions for the surgeon. Though further investigations should be conducted, adopting the between-standing position deserves serious consideration as it may be the best short-term ergonomic alternative.

The Global Operative Assessment of Laparoscopic Skills (GOALS) is a valid and reliable measure of basic, non-procedure-specific laparoscopic skills. GOALS-incisional hernia (GOALS-IH) was developed to evaluate performance of laparoscopic incisional hernia repair (LIHR). The purpose of this study was to assess the validity and reliability of GOALS-IH during LIHR simulation. GOALS-IH assesses 7 domains with a maximum score of 35. A total of 12 experienced surgeons and 10 novices performed LIHR on the Surgical Abdominal Wall simulator. Performance was assessed by a trained observer and by self-assessment using GOALS-IH, basic GOALS and a visual analog scale (VAS) for overall competence. Both interrater reliability and internal consistency were high (.76 and .95 respectively). Experienced surgeons had higher mean GOALS-IH scores than novices (32.3 ± 2 versus 22.7 ± 5). There was excellent correlation between GOALS-IH and other measures of performance (GOALS r = .93 and VAS r = .93). GOALS-IH is easy to use, valid and reliable for assessment of simulated LIHR.

Background: Minimally invasive surgery requires high-quality imaging to provide effective visual displays to surgeons. Whereas objective measures--pixels, resolution, display size, contrast ratio--are used to compare imaging systems, there are no tools for assessing the perceptual impact of these physical measures. We developed the "Maryland Visual Comfort Scale" (MVCS) to measure perceptual qualities in relation to an imaging system. We theorize that what the surgeon perceives as a high-quality image can be summarized by a scoring of seven characteristics related to human perception, and that image quality is not homogenous across a video display such that object location impacts perception and display quality., Method: We created a rating scale for seven dimensions of display characteristics (contrast, detail, brightness, lighting uniformity, focus uniformity, color, sharpness). For validation, 30 participants viewed test patterns and manipulated physiologic images, rating the image quality for all seven dimensions as well as giving an overall rating. Image ratings for contrast and detail dimensions were assessed across five locations on the video display. For ratings, two imaging systems were used, differing primarily in the 10-mm zero-degree scope's quality: a standard scope and one taken from service for quality degradation., Results: The rating scale was sensitive to differences in scope quality for all seven items in the MVCS (all p values<0.01). Significant differences existed between quality ratings at central and peripheral locations (p<0.05)., Conclusions: This seven-item rating scale for assessing visual comfort is reliable and sensitive to scope quality differences. The scale is sensitive to degradation of image quality at video display edges. These seven dimensions of display characteristics can be refined to create a psychometric to serve as a composite of perceptual quality in laparoscopy.

Lesion segmentation involves outlining the contour of an abnormality on an image to distinguish boundaries between normal and abnormal tissue and is essential to track malignant and benign disease in medical imaging for clinical, research, and treatment purposes. A laser optical mouse and a graphics tablet were used by radiologists to segment 12 simulated reference lesions per subject in two groups (one group comprised three lesion morphologies in two sizes, one for each input device for each device two sets of six, composed of three morphologies in two sizes each). Time for segmentation was recorded. Subjects completed an opinion survey following segmentation. Error in contour segmentation was calculated using root mean square error. Error in area of segmentation was calculated compared to the reference lesion. 11 radiologists segmented a total of 132 simulated lesions. Overall error in contour segmentation was less with the graphics tablet than with the mouse (P < 0.0001). Error in area of segmentation was not significantly different between the tablet and the mouse (P = 0.62). Time for segmentation was less with the tablet than the mouse (P = 0.011). All subjects preferred the graphics tablet for future segmentation (P = 0.011) and felt subjectively that the tablet was faster, easier, and more accurate (P = 0.0005). For purposes in which accuracy in contour of lesion segmentation is of the greater importance, the graphics tablet is superior to the mouse in accuracy with a small speed benefit. For purposes in which accuracy of area of lesion segmentation is of greater importance, the graphics tablet and mouse are equally accurate.

Purpose: The use of pharmacy delivery robots in an institution's intensive care units was evaluated., Summary: In 2003, the University of Maryland Medical Center (UMMC) began a pilot program to determine the logistic capability and functional utility of robotic technology in the delivery of medications from satellite pharmacies to patient care units. Three satellite pharmacies currently used the robotic system. Five data sources (electronic robot activation records, logs, interviews, surveys, and observations) were used to assess five key aspects of robotic delivery: robot use, reliability, timeliness, cost minimization, and acceptance. A 19-item survey using a 7-point Likert-type scale was developed to determine if pharmacy delivery robots changed nurses' perception of pharmacy service. The components measured included general satisfaction, reliability, timeliness, stat orders, services, interaction with pharmacy, and status tracking. A total of 23 pre-implementation, 96 post-implementation, and 30 two-year follow-up surveys were completed. After implementation of the robotic delivery system, time from fax to label, order preparation time, and idle time for medications to be delivered decreased, while nurses' general satisfaction with the pharmacy and opinion of the reliability of pharmacy delivery significantly increased. Robotic delivery did not influence the perceived quality of delivery service or the timeliness of orders or stat orders. Robot reliability was a major issue for the technician but not for pharmacists, who did not have as much interaction with the devices., Conclusion: By considering the needs of UMMC and its patients and matching them with available technology, the institution was able to improve the medication-use process and timeliness of medication departure from the pharmacy.

We describe a two-handed immersive and distributed 3D medical system that enables intuitive interaction with multimedia objects and space. The system is applicable to a number of virtual reality and tele-consulting scenarios. Various features were implemented, including measurement tools, interactive segmentation, non-orthogonal planar views, and 3D markup. User studies demonstrated the system's effectiveness in fundamental 3D tasks, showing that iMedic's two-handed interface enables placement and construction of 3D objects 4.5-4.7 times as fast as a mouse interface and 1.3-1.7 times as fast as a one-handed wand interface. In addition, avatar-to-avatar collaboration (two iMedic users in a shared space-one subject and one mentor) was shown to be more effective than face-to-face collaboration (one iMedic user/subject and one live mentor) for three tasks.

Background: the role of simulation for training in procedures such as laparoscopic incisional hernia repair (LIHR) is unknown. The purpose of this study was to determine whether performance in simulated LIHR correlates with operating room (OR) performance., Methods: subjects performed LIHR in the University of Maryland Surgical Abdominal Wall (SAW) simulator and the OR. Trained observers used a LIHR-specific global rating scale (Global Operative Assessment of Laparoscopic Skills-Incisional Hernia) to assess performance. Global Operative Assessment of Laparoscopic Skills-Incisional Hernia includes 7 domains (trocar placement, adhesiolysis, mesh sizing, mesh positioning, mesh fixation, knowledge and autonomy in instrument use, and overall competence). The correlation between simulator and OR performance was assessed using the Pearson coefficient., Results: fourteen surgeons from 2 surgical departments participated. Experienced surgeons (n = 9) were defined as attending surgeons and minimally invasive surgury (MIS) fellows, and novice surgeons (n = 5) were general surgery residents (postgraduate years 3-5). The correlation between performance in the OR and the simulator for the entire group was .87 (95% confidence interval, .63-.96; P < .001)., Conclusions: there was an excellent correlation between LIHR performance in the simulator and clinical LIHR. This suggests that performance in the SAW simulator may predict performance in the operating room., (2011 Elsevier Inc. All rights reserved.)

Background: The widely held belief that laparoscopy causes greater strain on surgeons' bodies than open surgery is not well documented in scope or magnitude. In the largest North American survey to date, we investigated the association of demographics, ergonomics, and environment and equipment with physical symptoms reported by laparoscopic surgeons., Study Design: There were 317 surgeons identified as involved in laparoscopic practices who completed the online survey. Data collected from this comprehensive 23-question survey were analyzed using chi-square., Results: There were 272 laparoscopic surgeons (86.9%) who reported physical symptoms or discomfort. The strongest predictor of symptoms was high case volume, with the surprising exceptions of eye and back symptoms, which were consistently reported even with low case volumes. High rates of neck, hand, and lower extremity symptoms correlated with fellowship training, which is strongly associated with high case volume. Surprisingly, symptoms were little related to age, height, or practice length. The level of surgeons' awareness of ergonomic guidelines proved to be somewhere between slightly and somewhat aware. A substantial number of respondents requested improvements in regard to both the positioning and resolution of the monitor., Conclusions: Far beyond previous reports of 20% to 30% incidence of occupational injury, we present evidence that 87% of surgeons who regularly perform minimally invasive surgery suffer such symptoms or injuries, primarily high case load-associated. Additional data accrual and analysis are necessary, as laparoscopic procedures become more prevalent, for improvement of surgeon-patient and surgeon-technology interfaces to reverse this trend and halt the epidemic before it is upon us., (Copyright 2010 American College of Surgeons.

There is precedent in medicine for recognizing and accepting intact decisional capacity and the subsequent ability to provide valid consent in one treatment domain, while simultaneously recognizing that the patient lacks decisional capacity in other domains. As such, obtaining consent for anesthesia for a surgical procedure is a separate entity from obtaining consent for the surgery itself. Anesthesia for surgery and the surgical procedure itself are separate treatment domains and as such require separate consents. Anesthesiologists should understand the independence of these functionally linked consent processes and be vigilant with respect to the informed consent process. The cases reported in this article show that capacity for surgical consent may be inadequate for consent to anesthesia because anesthesia involves more abstract concepts requiring a higher cognitive state than surgery, thus requiring a higher state of cognitive capacity for understanding.

Laparoscopic ventral hernia repair (LVHR) is a relatively common procedure that requires advanced minimally invasive surgical skills to perform. The role for simulation is increasingly supported as an effective way to teach surgical skills and accelerate the learning curve. This article describes The University of Maryland's Surgical Abdominal Wall, an inexpensive procedure-specific physical simulator for LVHR, and summarizes the authors' early experiences using this model in a curriculum for surgery residents.

Study Objective: We illustrate how audio-video data records can improve emergency medical care, using airway management to show how such video data may help to identify unsafe acts, accident precursors, and latent and systems failures and to evaluate performance., Methods: This was a retrospective analysis of videos of real patient resuscitation in a trauma center. Participant care providers reviewing their own videos of tracheal intubation identified failures to use diagnostic equipment, fixation errors, and team and communication errors., Results: Neutral expert observers noted team coordination failures and poor error recovery. Comparison with a consensus guideline for a tracheal intubation task/communication pathway showed that communications were unclear or not made, and key tasks were omitted by team members. Differences were detected between performance of tracheal intubation in elective and emergency circumstances. Revised practices ("3 Cs": clinical examination, communication, carbon dioxide) mitigated task performance and communication deficiencies., Conclusion: Video is complementary to traditional quality improvement methods for improving performance in airway management and emergency medical and trauma care, assessing standard operating procedures, and reviewing communications. Video data identify performance details not found in quality improvement approaches, including medical record review or recall by participant care providers. Weaknesses in using video for data include lengthy video review processes, poor audio, and the inability to adequately analyze events outside the field of view. Opportunities are to use video audit for quality improvement of other emergency tasks. Video buffering reduces personnel requirements for capture and simplifies data extraction. Medicolegal and confidentiality threats are significant.
