Improving patient and clinician safety during COVID-19 through rapidly adaptive simulation and a randomised controlled trial: a study protocol.

INTRODUCTION: COVID-19 required healthcare systems to iteratively adapt for safe and up-to-date care as knowledge of the disease rapidly evolved. Rates of COVID-19 infections continue to fluctuate and patients without COVID-19 increasingly return to the emergency department (ED) for care. This leads to new challenges and threats to patient and clinician safety as suspected patients with COVID-19 need to be quickly detected and isolated among other patients with non-COVID-19-related illnesses. At the front lines, emergency physicians also face continued personal safety concerns and increased work burden, which heighten stress and anxiety, especially given the prolonged course of the pandemic. Burnout, already a serious concern for emergency physicians due to the cumulative stresses of their daily practice, may present as a longer-term outcome of these acute stressors. METHODS AND ANALYSIS: We will implement a rapidly adaptive simulation-based approach to understand and improve physician preparedness while decreasing physician stress and anxiety. First, we will conduct semi-structured qualitative interviews and human factor observations to determine the challenges and facilitators of COVID-19 preparedness and mitigation of physician stress. Next, we will conduct a randomised controlled trial to test the effectiveness of a simulation preparedness intervention on physician physiological stress as measured by decreased heart rate variability on shift and anxiety as measured by the State-Trait Anxiety Inventory. ETHICS AND DISSEMINATION: The protocol was reviewed and approved by the Agency for Healthcare Research and Quality for funding, and ethics approval was obtained from the Yale University Human Investigation Committee in 2020 (HIC# 2000029370 and 2000029372). To support ongoing efforts to address clinician stress and preparedness, we will strategically disseminate the simulation intervention to areas most impacted by COVID-19. Using a virtual telesimulation and webinar format, the dissemination efforts will provide hands-on learning for ED and hospital administrators as well as simulation educators. TRIAL REGISTRATION NUMBER: NCT04614844.

All clinical stressors are not created equal: Differential task stress in a simulated clinical environment.

Background: A variety of stressors are encountered while working in the emergency department and are often recreated in simulation-based medical education. We seek to examine the physiologic and stress state response of participants in a simulated clinical environment to commonly encountered stressors. Methods: Emergency medicine (EM) residents participated in a randomized, controlled trial of six simulated patient encounters with one of three stressors, medical difficulty, interpersonal challenge, and technology/equipment failure, randomized into each scenario. Participants wore smart shirts to measure heart rate variability (HRV) at rest and just after the introduced stressor and completed the Short Stress State Questionnaire (SSSQ) before and after each scenario. Results: Twenty-seven EM residents participated in the study. Interpersonal challenge resulted in increased distress as measured by SSSQ compared to the other two stressors (one way ANOVA, F[2,144] = 9.95, p < 0.001). There was no difference in worry or task engagement across stressors. HRV decreased significantly from rest for all stressors (p = 0.0003, p = 0.0112, p = 0.0027 for medical difficulty, interpersonal challenge, and equipment failure, respectively), but there was no statistically significant difference between mean change in HRV across stressors (one way ANOVA, F[2,120] = 0.17, p = 0.8452). Conclusions: Interpersonal challenge stressor was significantly associated with an increase in distress in EM residents during the simulated encounters as compared to the other stressors. While heart rate variability decreased from rest for each stressor as expected following stressor introduction, differing stressors did not produce a differential change.

Just-in-time clinical video review improves successful placement of Sengstaken-Blakemore tube by emergency medicine resident physicians: A randomized control simulation-based study.

OBJECTIVE: Successful completion of life-saving procedures may benefit from a concise just-in-time (JIT) intervention. Video is an optimal medium for JIT training, but currently available video-based references are not optimized for a JIT format, especially in time-pressured situations prior to high-risk clinical contexts. We aimed to create and evaluate the efficacy of a brief video review of emergent Sengstaken-Blakemore tube (SBT) insertion for acutely decompensating variceal hemorrhage when used just prior to clinical performance in a simulated setting. METHODS: We created a less than 3-minute audio-optional JIT training video on SBT insertion. We recruited emergency medicine resident physicians to participate in a simulation scenario in which they had to quickly place an SBT. Participants were randomized to either a 3-minute procedure review by any media they chose (control) or review of the JIT video (intervention). Performance on a checklist created by a multidisciplinary group of SBT experts (passing score > 18 and maximum = 28) served as the primary outcome. We analyzed performance in checklist scores controlling level of training through a one-way analysis of covariance (ANCOVA). We analyzed rates of passing scores via a chi-square analysis. RESULTS: We randomized 32 participants to media review (control) or JIT video (intervention). The intervention group had an overall mean (±SD) performance of 19.8 (±9.0) and the control group had a mean (±SD) score of 6.6 (±7.4). After adjusting for postgraduate year, we found a significant difference in final checklist scores between the two groups (mean difference = 12.8, 95% confidence interval [CI] = 7.6 to 18.0). Percentages of participants reaching a minimum passing score were two of 16 (12.5%) in the control group and 10 of 16 (62.5%) in the intervention group (odds ratio = 11.7, 95% CI = 9.9 to 13.5). Cohen's kappa indicated substantial agreement (κ = 0.714) between reviewer scores. CONCLUSIONS: A readily available, focused, audio-optional JIT video increased performance for SBT insertion in a simulated setting. Future work may include testing of this format for more commonly performed emergency procedures and determination of effect on bedside performance in the clinical setting.

Virtual Telesimulation for Medical Students During the COVID-19 Pandemic.

PROBLEM: In March 2020, the novel coronavirus 2019 (COVID-19) became a global pandemic. Medical schools around the United States faced difficult decisions, temporarily suspending hospital-based clerkship rotations for medical students due to potential shortages of personal protective equipment and a need to social distance. This decision created a need for innovative, virtual learning opportunities to support undergraduate medical education. APPROACH: Educators at Yale School of Medicine developed a novel medical student curriculum converting high-fidelity, mannequin-based simulation into a fully online virtual telesimulation format. By using a virtual videoconferencing platform to deliver remote telesimulation as an immersive educational experience for widely dispersed students, this novel technology retains the experiential strengths of simulation-based learning while complying with needs for social distancing during the pandemic. The curriculum comprises simulated clinical scenarios that include live patient actors; facilitator interactions; and real-time assessment of vital signs, labs, and imaging. Each 90-minute session includes 2 sets of simulation scenarios and faculty-led teledebriefs. A team of 3 students performs the first scenario, while an additional team of 3 students observes. Teams reverse roles for the second scenario. OUTCOMES: The 6-week virtual telesimulation elective enrolled the maximum 48 medical students and covered core clinical clerkship content areas. Communication patterns within the virtual telesimulation format required more deliberate turn-taking than normal conversation. Using the chat function within the videoconferencing platform allowed teams to complete simultaneous tasks. A nurse confederate provided cues not available in the virtual telesimulation format. NEXT STEPS: Rapid dissemination of this program, including online webinars and live demonstration sessions with student volunteers, supports the development of similar programs at other universities. Evaluation and process improvement efforts include planned qualitative evaluation of this new format to further understand and refine the learning experience. Future work is needed to evaluate clinical skill development in this educational modality.

"To Err Is Human" but Disclosure Must be Taught: A Simulation-Based Assessment Study.

INTRODUCTION: Although error disclosure is critical in promoting safety and patient-centered care, physicians are inconsistently trained in its practice, and few objective methods to assess competence exist. We used an immersive simulation scenario to determine whether providers with varying levels of clinical experience adhere to the disclosure safe practice guidelines when exposed to a serious adverse event simulation scenario. METHODS: This was a prospective cohort study with medical students, junior emergency medicine (EM) residents (PGY 1-2), senior EM residents (PGY 3-4), and attending EM physicians participating in a simulated case in which a scripted medication overdose resulted in an adverse event. Each scenario was videotaped and scored by two expert raters based on a 6-component, 21-point disclosure assessment instrument. RESULTS: There were 12 participants in each study group (N = 48). There was good interrater reliability (κ = 0.70). Total scores improved significantly as the level of training increased: medical student = 10.3 (2.7), PGY 1-2 = 12.3 (6.2), PGY 3-4 = 13.7 (3.2), and attending physicians = 12.8 (3.7) (P = 0.03). Seventy-five percent of participants did not address preventing recurrence of the error. Fifty-six percent offered no apology or only offered it with prompting from the patient; only 23% offered an apology with the initial disclosure. CONCLUSIONS: We demonstrated suboptimal adherence to best practices guidelines for error disclosure when providers are assessed in an immersive simulation setting. Despite a correlation in performance of medical error disclosure with increased physician experience, this study suggests that healthcare providers may need additional training to comply with safe practice guidelines for disclosure of unanticipated adverse events.

Enhancement of Cricothyroidotomy Education Using a Novel Technique: Cadaver Autografting.

BACKGROUND: Cricothyroidotomy is a lifesaving procedure required in up to 2% of emergent airways. Emergency medicine training programs frequently instruct this procedure via cadaver training, but cadaver cost and availability limit the opportunity for all trainees to perform the critical initial skin incision. Cadaver autografting is a novel way to simulate all steps of the procedure. OBJECTIVE: Our aim was to determine whether the technique of autografting cadaver tissue improves the experience of cricothyroidotomy simulation education for emergency medicine trainees. The investigators hypothesized that autografted cadaver tissue would be a useful adjunct. METHODS: In this prospective crossover study, volunteers were randomized to first perform cricothyroidotomy on previously incised native neck tissue or on autografted tissue, and then vice versa. The autograft consisted of cadaver iliotibial band covered with lateral thigh skin and subcutaneous tissue to simulate cricothyroid membrane and native anterior neck anatomy. Volunteer emergency medicine residents and sub-interns were included. Twenty-seven residents and nine students participated. Outcomes were evaluated via Likert scale. RESULTS: Thirty of 36 (83%) participants agreed or strongly agreed that they preferred cadaver autografting to the previously incised native tissue. Thirty-two of 36 (89%) agreed or strongly agreed that cadaver autografting was useful vs. 23 of 36 (64%) who answered similarly regarding previously incised native tissue (p = 0.001). Twenty-six of 36 (72%) were more comfortable with cricothyroidotomy in the emergency department after using cadaver autografting vs. 19 of 36 (53%) after using the native tissue (p = 0.003). CONCLUSIONS: Autografted cadaver tissue while simulating cricothyroidotomy was perceived to be a useful adjunct by the majority of participating emergency medicine trainees.

A comprehensive, simulation-based approach to teaching clinical skills: the medical students' perspective.

The purpose of this study was to determine if third-year medical students participating in a mandatory 12-week simulation course perceived improvement in decision-making, communication, and teamwork skills. Students participated in or observed 24 acute emergency scenarios. At 4-week intervals, students completed 0-10 point Likert scale questionnaires evaluating the curriculum and role of team leader. Linear contrasts were used to examine changes in outcomes. P-values were Bonferroni-corrected for multiple pairwise comparisons. Student evaluations (n = 96) demonstrated increases from week 4 to 12 in educational value (p = 0.006), decision-making (p < 0.001), communication (p = 0.02), teamwork (p = 0.01), confidence in management (p < 0.001), and translation to clinical experience (p < 0.001). Regarding the team leader role, students reported a decrease in stress (p = 0.001) and increase in ability to facilitate team function (p < 0.001) and awareness of team building (p = <0.001). Ratings demonstrate a positive impact of simulation on both clinical management skills and team leadership skills. A simulation curriculum can enhance the ability to manage acute clinical problems and translates well to the clinical experience. These positive perceptions increase as the exposure to simulation increases.
