Why can't we improve turnover time? A systematic review.

BACKGROUND: Despite substantial efforts to reduce operating room (OR) turnover time (TOT), delays remain a frustration to physicians, staff, and hospital leadership. These efforts have employed many systems and human factor-based approaches with variable results. A deeper dive into methodologies and their applicability could lead to successful and sustained change. The aim of this study was to conduct a systematic review to evaluate relevant research focused on improving OR TOT and clearly defining measures of successful intervention. MATERIAL AND METHODS: A systematic review of OR TOT interventions implemented between 1980 through October 2022 was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Research databases included: 1) PubMed; 2) Web of Science; and 3) OVID Medline. RESULTS: A total of 38 articles were appropriate for analysis. Most employed a pre/post intervention approach (29, 76.3%), the remaining utilized a control/intervention approach. Nine intervention methods were identified: the majority included a process redesign bundle (24, 63%), followed by overlapping induction, dedicated unit/team/space feedback, financial incentives, team training, education, practice guidelines, and redefinition of roles/responsibilities. Studies were further categorized into one of two groups: (1) those that utilized predetermined interventions based on anecdotal experience or prior literature (18, 47.4%) and (2) those that conducted a prospective analysis on baseline data to inform intervention development (20, 52.6%). DISCUSSION: There are significant variability in the methodologies utilized to improve OR TOT; however, the most effective solutions involved process redesign bundles developed from a prospective investigation of the clinical work-system.

Medication Safety Event Reporting: Factors That Contribute to Safety Events During Times of Organizational Stress.

BACKGROUND: Incident reports submitted during times of organizational stress may reveal unique insights. PURPOSE: To understand the insights conveyed in hospital incident reports about how work system factors affected medication safety during a coronavirus disease-2019 (COVID-19) surge. METHODS: We randomly selected 100 medication safety incident reports from an academic medical center (December 2020 to January 2021), identified near misses and errors, and classified contributing work system factors using the Human Factors Analysis and Classification System-Healthcare. RESULTS: Among 35 near misses/errors, incident reports described contributing factors (mean 1.3/report) involving skill-based errors (n = 20), communication (n = 8), and tools/technology (n = 4). Reporters linked 7 events to COVID-19. CONCLUSIONS: Skill-based errors were the most common contributing factors for medication safety events during a COVID-19 surge. Reporters rarely deemed events to be related to COVID-19, despite the tremendous strain of the surge on nurses. Future efforts to improve the utility of incident reports should emphasize the importance of describing work system factors.

Barriers to safety and efficiency in robotic surgery docking.

BACKGROUND: The introduction of new technology into the operating room (OR) can be beneficial for patients, but can also create new problems and complexities for physicians and staff. The observation of flow disruptions (FDs)-small deviations from the optimal course of care-can be used to understand how systems problems manifest. Prior studies showed that the docking process in robotic assisted surgery (RAS), which requires careful management of process, people, technology and working environment, might be a particularly challenging part of the operation. We sought to explore variation across multiple clinical sites and procedures; and to examine the sources of those disruptions. METHODS: Trained observers recorded FDs during 45 procedures across multiple specialties at three different hospitals. The rate of FDs was compared across surgical phases, sites, and types of procedure. A work-system flow of the RAS docking procedure was used to determine which steps were most disrupted. RESULTS: The docking process was significantly more disrupted than other procedural phases, with no effect of hospital site, and a potential interaction with procedure type. Particular challenges were encountered in room organization, retrieval of supplies, positioning the patient, and maneuvering the robot. CONCLUSIONS: Direct observation of surgical procedures can help to identify approaches to improve the design of technology and procedures, the training of staff, and configuration of the OR environment, with the eventual goal of improving safety, efficiency and teamwork in high technology surgery.

The Application of Human Factors Engineering to Reduce Operating Room Turnover in Robotic Surgery.

BACKGROUND: Challenges associated with turnover time are magnified in robotic surgery. The introduction of advanced technology increases the complexity of an already intricate perioperative environment. We applied a human factors approach to develop systematic, data-driven interventions to reduce robotic surgery turnover time. METHODS: Researchers observed 40 robotic surgery turnovers at a tertiary hospital [20 pre-intervention (Jan 2018 to Apr 2018), 20 post-intervention (Jan 2019 to Jun 2019)]. Components of turnover time, including cleaning, instrument and room set-up, robot preparation, flow disruptions, and major delays, were documented and analyzed. Surveys and focus groups were used to investigate staff perceptions of robotic surgery turnover time. A multidisciplinary team of human factors experts and physicians developed targeted interventions. Pre- and post-intervention turnovers were compared. RESULTS: Median turnover time was 67 min (mean: 72, SD: 24) and 22 major delays were noted (1.1/case). The largest contributors were instrument setup (25.5 min) and cleaning (25 min). Interventions included an electronic dashboard for turnover time reporting, clear designation of roles and simultaneous completion of tasks, process standardization of operating room cleaning, and data transparency through monthly reporting. Post-intervention turnovers were significantly shorter (U = 57.5, p = .000) and ten major delays were noted. CONCLUSIONS: Human factors analysis generated interventions to improve turnover time. Significant improvements were seen post-intervention with a reduction in turnover time by a 26 min and decrease in major delays by over 50%. Future opportunities to intervene and further improve turnover time include targeting pre- and post-operative care phases.

A Human Factors Approach to Vaginal Retained Foreign Objects.

STUDY OBJECTIVE: This study aimed to apply a structured human factors analysis to understand conditions contributing to vaginal retained foreign objects (RFOs). DESIGN: All potential vaginal RFO events from January 1, 2000, to May 21, 2019, were analyzed by trained human factors researchers. Each narrative was reviewed to identify contributing factors, classified using the Human Factors Analysis and Classification System for Healthcare. SETTING: An 890-bed, academic medical center in Southern California. PATIENTS: Patients who underwent a vaginal procedure in which a vaginal RFO-related event occurred were included in this study. However, no patient information was included, and only the relevant details from their procedures were included. INTERVENTIONS: No interventions were developed or implemented. MEASUREMENTS AND MAIN RESULTS: Over the 19-year period, 45 events were reported. The most common items were vaginal packing and vaginal sponges (53.33%). Less frequently retained items involved broken instruments (20.20%). Most cases were laparoscopic hysterectomies or vaginal deliveries. Based on the Human Factors Analysis and Classification System, 75 contributing factors were identified, consisting primarily of preconditions for unsafe acts (communication challenges, coordination breakdowns and issues with the design of tools/technology) and unsafe acts (errors). CONCLUSION: Although rare, vaginal RFOs do occur. The top 2 contributing factors were skill-based errors and communication breakdowns. Both types of errors can be addressed and improved with human factors interventions, including simulation, teamwork training, and streamlining workflow to reduce the opportunity for errors.

Human Factors Integration in Robotic Surgery.

OBJECTIVE: Using the example of robotic-assisted surgery (RAS), we explore the methodological and practical challenges of technology integration in surgery, provide examples of evidence-based improvements, and discuss the importance of systems engineering and clinical human factors research and practice. BACKGROUND: New operating room technologies offer potential benefits for patients and staff, yet also present challenges for physical, procedural, team, and organizational integration. Historically, RAS implementation has focused on establishing the technical skills of the surgeon on the console, and has not systematically addressed the new skills required for other team members, the use of the workspace, or the organizational changes. RESULTS: Human factors studies of robotic surgery have demonstrated not just the effects of these hidden complexities on people, teams, processes, and proximal outcomes, but also have been able to analyze and explain in detail why they happen and offer methods to address them. We review studies on workload, communication, workflow, workspace, and coordination in robotic surgery, and then discuss the potential for improvement that these studies suggest within the wider healthcare system. CONCLUSION: There is a growing need to understand and develop approaches to safety and quality improvement through human-systems integration at the frontline of care.Precis: The introduction of robotic surgery has exposed under-acknowledged complexities of introducing complex technology into operating rooms. We explore the methodological and practical challenges, provide examples of evidence-based improvements, and discuss the implications for systems engineering and clinical human factors research and practice.

Work-system interventions in robotic-assisted surgery: a systematic review exploring the gap between challenges and solutions.

BACKGROUND: The introduction of a robot into the surgical suite changes the dynamics of the work-system, creating new opportunities for both success and failure. An extensive amount of research has identified a range of barriers to safety and efficiency in Robotic Assisted Surgery (RAS), such as communication breakdowns, coordination failures, equipment issues, and technological malfunctions. However, there exists very few solutions to these barriers. The purpose of this review was to identify the gap between identified RAS work-system barriers and interventions developed to address those barriers. METHODS: A search from three databases (PubMed, Web of Science, and Ovid Medline) was conducted for literature discussing system-level interventions for RAS that were published between January 1, 1985 to March 17, 2020. Articles describing interventions for systems-level issues that did not involve technical skills in RAS were eligible for inclusion. RESULTS: A total of 30 articles were included in the review. Only seven articles (23.33%) implemented and evaluated interventions, while the remaining 23 articles (76.67%) provided suggested interventions for issues in RAS. Major barriers identified included disruptions, ergonomic issues, safety and efficiency, communication, and non-technical skills. Common solutions involved team training, checklist development, and workspace redesign. CONCLUSION: The review identified a significant gap between issues and solutions in RAS. While it is important to continue identifying how the complexities of RAS affect operating room (OR) and team dynamics, future work will need to address existing issues with interventions that have been tested and evaluated. In particular, improving RAS-associated non-technical skills, task management, and technology management may lead to improved OR dynamics associated with greater efficiency, reduced costs, and better systems-level outcomes.

An Evaluation of Fish Tissue Monitoring Alternatives for Mercury and Selenium: Fish Muscle Biopsy Samples Versus Homogenized Whole Fillets.

Fish contaminant studies with human health protection objectives typically focus on muscle tissue, recognizing that fillets are the commonly consumed tissue fraction. Muscle biopsy punch sampling for mercury analysis has recently been used as an alternative to harvesting fish for fillets; however, there is limited information comparing fillet plug results to whole fillet results. This study was conducted to address that data gap and to test the applicability of plugs for monitoring associated with United States Environmental Protection Agency's fish tissue-based mercury and selenium water quality criteria. The mercury phase included 300 fillet homogenates and 300 field-extracted plug samples from 60 fish, and the selenium phase included 120 fillet homogenates and 120 plugs from 30 fish. Both phases showed that there were no statistically significant differences between fillet plug and homogenized fillet results at the community level; however, a selenium plug monitoring alternative must employ a sufficiently sensitive analytical method and consider total solids. Plug and fillet sampling alternatives have inherent advantages and disadvantages. Fillet sampling provides sufficient mass to consider multiple contaminants but requires fish to be harvested. Plug sampling only provides adequate mass for a single analyte but may allow fish survival, although additional research is needed on survival following plug removal.

Flow disruptions in robotic-assisted abdominal sacrocolpopexy: does robotic surgery introduce unforeseen challenges for gynecologic surgeons?

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to apply a human factors research approach to identify flow disruptions, deviations in the optimal course of care, in robotic abdominal sacrocolpopexy procedures with the ultimate goal of developing system interventions to improve the safety and efficiency of robotic surgery. METHODS: Twenty-four robotic abdominal sacrocolpopexy procedures were observed for flow disruptions. Surgeries were divided into four phases: (1) patient arrival and induction of anesthesia; (2) port placement and robot docking; (3) console time; (4) undocking of robot, incision closure, and patient exiting the OR. RESULTS: Flow disruptions were observed at a rate of 10.9 ± 5.1 per hour. The most frequently observed flow disruptions involved training issues (2.8 ± 2.4 flow disruptions per hour), equipment (2.2 ± 1.6 flow disruptions per hour), and poor coordination (2.0 ± 1.3 flow disruptions per hour). The rate of flow disruptions was highest in phase 2 (19.2 ± 14.4 flow disruptions per hour). Cases with more experienced surgeons involved shorter console times by 1.5 h (95% CI: 0.1, 3.0, p = 0.033) and 1.8 fewer (95% CI: 1.2, 2.6, p = 0.001) flow disruptions per hour. Surgeries were 1 h shorter on average (95% CI: 0.1, 1.9, p = 0.034) in cases in which the patient was > 65 years old. Da Vinci S console times were 0.8 h longer (95% CI: 0.01, 1.5, p = 0.047) than Si. CONCLUSIONS: Flow disruptions in robotic abdominal sacrocolpopexy surgery occur about every 6 min. Flow disruption rates are highest during the most complex portions of the surgery. More experienced surgeons have lower flow disruption rates and operate more quickly.

A Data-Driven Approach to Team Training for Nurses in a Level II Trauma Center.

This prospective investigation describes the process of designing a targeted, data-driven team training aimed at reducing identified process inefficiencies or flow disruptions (FDs) that threaten the optimal delivery of trauma care. Trained researchers observed and classified FDs during 34 trauma cases in a Level II trauma center. Multidisciplinary trauma personnel generated interventions to identified issues using the human factors intervention matrix (HFIX). This article focuses on one intervention: a formal trauma nurse training program centered around leadership, teamwork, and communication. The training was well perceived and was found to have a significant impact on participant knowledge of course content; t (65) = -13.92, p ≤ .01. By using hospital-specific data to drive intervention development from multidisciplinary team members, it is possible to develop effective solutions aimed at addressing individual threats.

Intelligent Emergency Department: Validation of Sociometers to Study Workload.

Sociometers are wearable sensors that continuously measure body movements, interactions, and speech. The purpose of this study is to test sociometers in a smart environment in a live clinical setting, to assess their reliability in capturing and quantifying data. The long-term goal of this work is to create an intelligent emergency department that captures real-time human interactions using sociometers to sense current system dynamics, predict future state, and continuously learn to enable the highest levels of emergency care delivery. Ten actors wore the devices during five simulated scenarios in the emergency care wards at a large non-profit medical institution. For each scenario, actors recited prewritten or structured dialogue while independent variables, e.g., distance, angle, obstructions, speech behavior, were independently controlled. Data streams from the sociometers were compared to gold standard video and audio data captured by two ward and hallway cameras. Sociometers distinguished body movement differences in mean angular velocity between individuals sitting, standing, walking intermittently, and walking continuously. Face-to-face (F2F) interactions were not detected when individuals were offset by 30°, 60°, and 180° angles. Under ideal F2F conditions, interactions were detected 50 % of the time (4/8 actor pairs). Proximity between individuals was detected for 13/15 actor pairs. Devices underestimated the mean duration of speech by 30-44 s, but were effective at distinguishing the dominant speaker. The results inform engineers to refine sociometers and provide health system researchers a tool for quantifying the dynamics and behaviors in complex and unpredictable healthcare environments such as emergency care.

The Application of Human Factors Approaches to Improve Safety, Efficiency and Well-being in Urology: A Systematic Scoping Review.

OBJECTIVE: To elucidate the application of HF approaches within urology to improve clinical work-system function via a systematic scoping review. Human Factors (HF) plays an integral role to improving safety, efficiency, and well-being by optimizing work-system interactions. Despite its established application across various high-risk industries, the systematic exploration of HF methods applied within urology remains limited. METHODS: A scoping review of HF interventions implemented within urologic care from 1980 to 2023 was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Web of Science, PubMed, and OVID Medline databases were searched. Database searching resulted in 10,850 articles, after systematic review, 22 studies were included. RESULTS: The included studies predominantly originated from the United States and covered diverse areas of urology, including surgical procedures, diagnostics, and patient care. Interventions varied widely from ergonomic equipment implementations to modifications in clinical processes and team dynamics. Most studies utilized predetermined interventions based on prior literature or experiential anecdotes (15, 65.22%), while a smaller subset employed data-driven strategies to tailor interventions (8, 34.7%). The HF methods employed included questionnaires, retrospective reviews, observations, and physical measurements, targeting improvements in patient experiences, operational efficiencies, and clinical outcomes. CONCLUSION: This review underscores the emergent role of HF in urology, highlighting a broad spectrum of interventions and methodological approaches that contribute to system optimization. Future endeavors should focus on collaborative efforts to develop standardized HF applications in urology, promoting a safer, more efficient, and clinician-friendly environment.

Challenges With Robot-Assisted Surgery Setup for Complex Minimally Invasive Upper Gastrointestinal Surgery.

BACKGROUND: The utilization of robot-assisted approaches to surgery has increased significantly over the last two decades. This has introduced novel complexities into the operating room environment, requiring management of new challenges and workflow adaptation. This study aimed to analyze challenges in the surgical setup for complex upper gastrointestinal robot-assisted surgery (UGI-RAS) and identify opportunities for solutions. METHODS: Direct observations of surgical setup processes for UGI-RAS were performed by a trained Human Factors researcher at a non-profit academic medical center in Southern California. Setup tasks were subdivided into five phases: (1) before wheels-in; (2) patient transfer and anesthesia induction; (3) patient preparation; (4) surgery preparation; and (5) robot docking. Start/end times for each phase/task were documented along with workflow disruption (FD) narratives and timestamps. Setup tasks and FDs were analyzed using descriptive statistics. RESULTS: Twenty UGI-RAS setup procedures were observed between May-November 2023: sleeve gastrectomy +/- hiatal hernia repair (n = 9, 45.00%); para-esophageal hernia repair +/- fundoplication (n = 8, 40.00%); revision to Roux-en-Y gastric bypass (n = 2, 10.00%); and gastric band removal (n = 1, 5.00%). Frequent FDs included planning breakdowns (n = 20, 29.85%), equipment/supply management (n = 17, 25.37%), patient care coordination (n = 8, 11.94%), and equipment challenges (n = 8, 11.94%). Eleven of 20 observations were first-start cases, of which 10 experienced delayed starts. DISCUSSION: Interventions aimed at improving workflows during UGI-RAS setup include performing pre-operative team huddles and conducting trainings aimed at team coordination and equipment challenges. These solutions could result in improved teamwork, efficiency, and communication while reducing case start delays and turnover time.

The impact of resident training on robotic operative times: is there a July Effect?

It is unknown whether the July Effect (a theory that medical errors and organizational inefficiencies increase during the influx of new surgical residents) exists in urologic robotic-assisted surgery. The aim of this study was to investigate the impact of urology resident training on robotic operative times at the beginning of the academic year. A retrospective chart review was conducted for urologic robotic surgeries performed at a single institution between 2008 and 2019. Univariate and multivariate mix model analyses were performed to determine the association between operative time and patient age, estimated blood loss, case complexity, robotic surgical system (Si or Xi), and time of the academic year. Differences in surgery time and non-surgery time were assessed with/without resident presence. Operative time intervals were included in the analysis. Resident presence correlated with increased surgery time (38.6 min (p < 0.001)) and decreased non-surgery time (4.6 min (p < 0.001)). Surgery time involving residents decreased by 8.7 min after 4 months into the academic year (July-October), and by an additional 5.1 min after the next 4 months (p = 0.027, < 0.001). When compared across case types stratified by complexity, surgery time for cases with residents significantly varied. Cases without residents did not demonstrate such variability. Resident presence was associated with prolonged surgery time, with the largest effect occurring in the first 4 months and shortening later in the year. However, resident presence was associated with significantly reduced non-surgery time. These results help to understand how new trainees impact operating room times.

Rehabilitation Treatment Specification System for Voice Therapy: Application to Everyday Clinical Care.

PURPOSE: Rehabilitation intervention descriptions often do not explicitly identify active ingredients or how those ingredients lead to changes in patient functioning. The Rehabilitation Treatment Specification System (RTSS) provides guidance to identify the critical aspects of any rehabilitation therapy and supported the development of standardly named ingredients and targets in voice therapy (Rehabilitation Treatment Specification System for Voice Therapy [RTSS-Voice]). This study sought to test the content validity of the RTSS-Voice and determine if the RTSS-Voice can be used to identify commonalities and differences in treatment (criterion validity) across clinicians in everyday clinical practice. METHOD: Five speech-language pathologists from different institutions videotaped one therapy session for 59 patients diagnosed with a voice or upper airway disorder. Specifications were created for each video, and iterative rounds of revisions were completed with the treating clinician and two RTSS experts until consensus was reached on each specification. RESULTS: All 59 sessions were specified without the addition of any targets or ingredients. There were two frequent targets: (a) increased volition and (b) decreased strained voice quality. There were three frequent ingredients: (a) information regarding the patient's capability and motivation to perform a therapeutic behavior, (b) knowledge of results feedback, and (c) opportunities to practice voicing with improved resonance and mean airflow. Across sessions treating vocal hyperfunction, there was large variability across clinicians regarding the types and number of treatment components introduced, types of feedback provided, and vocal practice within spontaneous speech and negative practice. CONCLUSIONS: The RTSS and the RTSS-Voice demonstrated strong content validity, as they comprehensively characterized 59 therapy sessions. They also demonstrated strong criterion validity, as commonalities and differences were identified in everyday voice therapy for vocal hyperfunction across multiple clinicians. Future work to translate RTSS principles and RTSS-Voice terms into clinical documentation can help to understand how clinician and patient variability impacts outcomes and bridge the research-practice gap.

Floating Ball Voice Therapy: Preliminary Effects on Outcomes and Predicting Individual Patient Differences in Generalization.

PURPOSE: Floating ball voice therapy (FBVT) is a voice-controlled virtual environment based on a common treatment component across multiple evidence-based therapies: improved vocal efficiency (target) via practicing voicing with modified resonance and airflow (ingredient). This study preliminarily tested FBVT's effects on outcomes and the potential for its novel variability metrics to predict individual patient generalization. METHOD: Ten patients with nonphonotraumatic vocal hyperfunction (NPVH) practiced FBVT for 10 days. Outcomes were assessed by a vocal efficiency ratio, a validated NPVH index, the patient-reported Voice-Related Quality of Life (V-RQOL), and forced-choice auditory judgments of overall severity. Exploration in early practice (Day 1) was estimated by how the patient's two-dimensional variability (mean airflow and intensity) related to error (difference between the patient-produced and normative vocal efficiency ratio). Generalization from the game to spontaneous speech was evaluated using the validated NPVH index. RESULTS: Ten days of FBVT were associated with improved vocal efficiency (Cohen's d = 1.3), NPVH index (d = -1.1), V-RQOL total score (d = 0.9), and overall severity (odds ratio = 2.5). Patients who generalized on Day 10 exhibited airflow/intensity exploration that was more aligned with the error gradient on Day 1 (d = 0.6-1.2). CONCLUSIONS: A relatively small dosage of FBVT (i.e., 10 practice sessions) was associated with multiple improved voice therapy outcomes. The FBVT variability metrics on Practice Day 1 demonstrated strong potential to predict which patients generalized to connected speech. Future work can more thoroughly evaluate effects on outcomes and characterizing the quality of vocal exploration with a larger patient population.

Female sexual health digital resources: women and health care providers need more options.

INTRODUCTION: Female sexual health and female sexual dysfunction (FSD) are usually poorly diagnosed and treated because of the numerous barriers providers and patients face. Internet platforms, such as mobile applications (apps) are potential tools that help overcome these barriers and improve patient access to education and management options for FSD. OBJECTIVES: The aim of this review was to identify existing applications on female sexual health and evaluate their educational content and services. METHODS: We searched the internet and Apple App Store using multiple keywords. A panel of physicians specialized in the treatment of FSD reviewed the apps for content quality, the scientific basis of provided information, interactivity, usability, and whether they would recommend it as a reference tool for patients. RESULTS: Of the 204 apps identified, 17 met the inclusion criteria and were reviewed further. The selected apps were organized into groups based on common themes such as educational (n = 6), emotions and communication (n = 2), relaxation and meditation (n = 4), general sexual health (n = 2), and social and fun (n = 3). All apps from the educational category provided scientific information in collaboration with health experts. When assessed for usability, 1 app received good and 5 received excellent scores based on the System Usability Scale. Most apps (n = 5) provided information on pathology and treatments of orgasmic dysfunction, but only 1 app, created by a physician, provided comprehensive information on all the types of FSD. CONCLUSION: Digital technology could be an effective way to overcome barriers to accessing information and ultimately care for female sexual health. Our review demonstrated that there is still a need for more accessible educational resources addressing female sexual health and FSD for patients and providers.

Demands of surgical teams in robotic-assisted surgery: An assessment of intraoperative workload within different surgical specialties.

BACKGROUND: Current approaches to assessing workload in robotic-assisted surgery (RAS) focus on surgeons and lack real-world data. Understanding how workload varies by role and specialty aids in identifying effective ways to optimize workload. METHODS: SURG-TLX surveys with six domains of workload were administered to surgical staff at three sites. Staff reported workload perceptions for each domain on a 20-point Likert scale, and aggregate scores were determined per participant. RESULTS: 188 questionnaires were obtained across 90 RAS procedures. Significantly higher aggregate scores were reported for gynecology (Mdn â€‹= â€‹30.00) (p â€‹= â€‹0.034) and urology (Mdn â€‹= â€‹36.50) (p â€‹= â€‹0.006) than for general (Mdn â€‹= â€‹25.00). Surgeons reported significantly higher scores for task complexity (Mdn â€‹= â€‹8.00) than both technicians (Mdn â€‹= â€‹5.00) (p â€‹= â€‹0.007), and nurses (Mdn â€‹= â€‹5.00). CONCLUSIONS: Staff reported significantly higher workload during urology and gynecology procedures, and experienced significant differences in domain workload by role and specialty, elucidating the need for tailored workload interventions.

Contaminants in fish from U.S. rivers: Probability-based national assessments.

Most fish consumption advisories in the United States (U.S.) are issued for mercury and polychlorinated biphenyls (PCBs), and recently per- and polyfluoroalkyl substances (PFAS) have become a contaminant group that warrants fish consumption advice. An unequal probability survey design was developed to allow a comprehensive characterization of mercury, PCB, and PFAS contamination in fish from U.S. rivers on a national scale. During 2013-14 and 2018-19, fish fillet samples were collected from 353 and 290 river sites, respectively, selected randomly from the target population of rivers (≥5th order in size) in the conterminous U.S. These comprised nationally representative samples, with results extrapolated to chemical-specific sampled populations of 48,826-79,448 river kilometers (km) in 2013-14 and 66,142 river km in 2018-19. National distribution estimates were developed for total mercury, all 209 PCB congeners, and up to 33 PFAS (including perfluorooctane sulfonate or PFOS) in river fish. All fillet tissue samples contained detectable levels of mercury and PCBs. One or more PFAS were detected in 99.7 % and 95.2 % of the fillet samples from fish collected in 2013-14 and 2018-19, respectively. Fish tissue screening levels applied to national contaminant probability distributions allowed an estimation of the percentage of the sampled population of river lengths that contained fish with fillet concentrations above a level protective of human health. Fish tissue screening level exceedances for an average level of fish consumption ranged from 23.5 % to 26.0 % for mercury, 17.3 % to 51.6 % for PCBs, and 0.7 % to 9.1 % for PFOS.

Understanding ultrarare adverse events - Lessons learned from a twelve-year review of intraoperative deaths at an academic medical center.

BACKGROUND: Intraoperative death (ID) is rare, the incidence remains challenging to quantify and learning opportunities are limited. We aimed to better define the demographics of ID by reviewing the longest single-site series. METHODS: Retrospective chart reviews, including a review of contemporaneous incident reports, were performed on all ID between March 2010 to August 2022 at an academic medical center. RESULTS: Over 12 years, 154 IDs occurred (∼13/year, average age: 54.3 years, male: 60%). Most occurred during emergency procedures (n = 115, 74.7%), 39 (25.3%) during elective procedures. Incident reports were submitted in 129 cases (84%). 21 (16.3%) reports cited 28 contributing factors including challenges with coordination (n = 8, 28.6%), skill-based errors (n = 7, 25.0%), and environmental factors (n = 3, 10.7%). CONCLUSIONS: Most deaths occurred in patients admitted from the ER with general surgical problems. Despite expectations for incident reporting, few provided actionable information on ergonomic factors which might help identify improvement opportunities.
