Simulation-based interdisciplinary education improves intern attitudes and outlook toward colleagues in other disciplines.

BACKGROUND: Cooperative interdisciplinary patient care is a modern healthcare necessity. While various medical and surgical disciplines have independent educational requirements, a system-wide simulation-based curriculum composed of different disciplines provides a unique forum to observe the effect of interdisciplinary simulation-based education (IDSE). Our hypothesis: IDSE positively affects intern outlook and attitudes towards other medical disciplines. METHODS: Using an established interdisciplinary simulation curriculum designed for first year interns, we explored the relative effect of IDSE on between-discipline intern attitudes in a convergent, parallel, mixed-methods study. Data sources included novel pre-post anonymous survey measurements (10-point Likert scale), focus groups, direct observations, and reflective field notes. This quasi-experimental pilot study was conducted at an academic, tertiary care medical center with two cohorts of interns: one exposed to IDSE and one exposed to an independent within-discipline simulation curriculum. RESULTS: IDSE exposed interns demonstrated statistically significant improvements when comparing mean pre-test and post-test score differences in five of seven areas: perceived interdisciplinary collegiality ([Formula: see text] = 0.855; p = 0.0002), respect (x̅ = 0.436; p = 0.0312), work interactions ([Formula: see text] = 0.691; p = 0.0069), perceived interdisciplinary attitudes (x̅ = 0.764; p = 0.0031), and comfort in interdisciplinary learning (x̅ = 1.164; p < 0.0001). There were no changes in interdisciplinary viewpoints observed among non-IDSE interns. IDSE interns were comfortable when learning with interns of different disciplines and believed others viewed their discipline positively compared to non-IDSE interns. Qualitative data uncovered the following themes related to the impact of IDSE including: 1) Relationship building, 2) Communication openness, 3) Attitude shifting, and 4) Enhanced learner experience. CONCLUSIONS: IDSE positively influenced intern outlook on and attitudes towards other medical disciplines. This unique learning environment provided interns an opportunity to learn clinical case management while learning about, from, and with each other; subsequently breaking traditional discipline-specific stereotypes and improving interdisciplinary relations. Future explicit focus on IDSE offers opportunity to improve interdisciplinary interactions and patient care.

Palliative care in the emergency department: an educational investigation and intervention.

BACKGROUND: To investigate the value of a novel simulation-based palliative care educational intervention within an emergency medicine (EM) residency curriculum. METHODS: A palliative care scenario was designed and implemented in the simulation program at an urban academic emergency department (ED) with a 3-year EM residency program. EM residents attended one of eight high-fidelity simulation sessions, in groups of 5-6. A standardized participant portrayed the patient's family member. One resident from each session managed the scenario while the others observed. A 45-min debriefing session and small group discussion followed the scenario, facilitated by an EM simulation faculty member and a resident investigator. Best practices in palliative care were highlighted along with focused learner performance feedback. Participants completed an anonymous pre/post education intervention survey. RESULTS: Forty of 42 EM residents (95%) participated in the study. Confidence in implementing palliative care skills and perceived importance of palliative care improved after this educational intervention. Specifically, residents 1) felt EM physicians had an important role in palliative care, 2) had increased confidence in the ability to determine patient decision-making capacity, 3) had improved confidence in initiating palliative discussions/treatment, 4) believed palliative education was important in residency, and 5) felt simulation was an effective means to learn palliative care. Differences noted between PGY1 and PGY 3 training levels in survey responses disappeared post-intervention. Residents noted being most comfortable with delivering bad news and symptom management and least comfortable with disease prognostication. Residents reported time constraints and implementation logistics in the ED as the most challenging factors for palliative care initiation. CONCLUSION: Our case-based simulation intervention was associated with an increase in both the perceived importance of ED palliative care and self-reported confidence in implementing palliative care skills. Time constraints and implementation logistics were rated as the most challenging factors for palliative care initiation in the ED.

Acute-on-Chronic Lithium Toxicity: A Simulation Case for Emergency Medicine Residents.

Introduction: Simulation-based education has become standard within emergency medicine training. Toxicological clinical presentations are challenging to identify and treat in the emergency department. Recognizing that active teaching methods are superior to standard lecture for learner retention, we created an experiential simulation case for education on lithium toxicity. The case was written after an extensive literature review followed by consultation with a medical toxicologist and an expert in simulation-based education. Methods: Fifty-three residents participated in a simulation scenario involving a lithium-poisoned patient over the course of eight simulation sessions. The scenario ran approximately 10 minutes and was followed by postevent debriefing. Debriefing was facilitated by an emergency medicine attending with specialized training in simulation-based education. Following the completion of the scenario, residents received an anonymous educational quality improvement survey assessing residents' perception of their ability to recognize and manage lithium toxicity as well as their comfort level with the lithium-poisoned patient. Results: After the simulation, residents reported an increased comfort level with managing lithium-poisoned patients. Residents also self-reported an increased ability to recognize the signs and symptoms of lithium toxicity. Additionally, residents cited the case's educational importance and a desire to include this specific scenario in future simulation sessions. Discussion: Compared to other disease processes, toxicological overdoses are infrequently seen in the emergency department. Health care simulation can effectively portray lithium toxicity for emergency medicine resident education in a safe, controlled environment to increase repetitive practice in caring for this challenging population.

Virtual Healthcare Simulation: Implementation, Distractions, and Preferences.

INTRODUCTION: Social distancing guidelines related to COVID-19 resulted in many simulation centers temporarily closing or adopting virtual simulation-based education (SBE). This mixed methods study aimed to evaluate our center's readiness to implement virtual SBE, the preferred method of delivery (virtual vs. nonvirtual), and any reported distractions. METHODS: Educators and simulation operations specialists (SOSs) used by our simulation center completed a survey focused on our center's implementation readiness for virtual SBE at 3 time points over a 3-week period. Three virtual simulation-based styles were developed: observer, vignette, and hybrid. All styles combined the use of Zoom and LearningSpace. Upon the completion of each session, learners, facilitators, and SOSs completed a survey focused on the preferred method of simulation delivery (virtual vs. nonvirtual) as well as any reported distractions during sessions. RESULTS: While some important lessons were learned, simulation team survey scores suggested an overall agreement in the center's preparedness during the 3-week implementation period. Most learners, facilitators, and SOSs preferred a nonvirtual delivery due to the "hands-on" component. Learners participating in the vignette style, however, significantly preferred virtual SBE due to "learning environment comfort" such as reduced anxiety, "better discussion," and "convenience." Reported distractions focused on "challenges with technology," "interruptions at home," "program logistics," and the "remote atmosphere." CONCLUSIONS: Most learners, facilitators, and SOSs preferred nonvirtual SBE; however, virtual SBE may prove beneficial for learners participating in the vignette style or particularly those experiencing anxiety. Future distractions may be mitigated for the simulation team and learners with proper preparedness.

Influence of Socioeconomic Bias on Emergency Medicine Resident Decision Making and Patient Care.

INTRODUCTION: Physician bias impacts clinical decision making, resulting in disparities in patient care. Most existing studies focus on sex and racial bias. This study aimed to investigate disparities in physician decision making among patients of varying socioeconomic status (SES). METHODS: Emergency medicine residents (n = 31) participated in 3 consecutive scenarios of similar disease acuity but with standardized patients of varying SES. Following the scenarios, residents met with a standardized participant acting as an attending physician for a handoff to recount their decision-making processes and care recommendations. Blinded raters evaluated clinical performance using an objective assessment tool. We assessed associations between patient SES and resident-ordered imaging, ordered medication, patient-perceived empathy, and clinical performance. We used qualitative analyses to study residents' decision-making processes. RESULTS: Quantitative analyses revealed no significant relationship between SES and resident-ordered imaging, ordered medications, patient-perceived empathy, and clinical performance. Qualitative analyses revealed 3 themes regarding clinical decision making: (1) overt diagnostic focus, (2) discharge planning, and (3) risk and exposure. CONCLUSIONS: Although quantitative analyses showed that SES did not affect clinical behavior within simulated scenarios, qualitative analyses uncovered 3 themes believed important to physician decision-making processes. Overt diagnostic focus may have resulted from the study environment in addition to organizational factors, policies, and training. Discharge planning, which was not explicitly studied, was often tailored to SES with emphasis placed on risks for patients of low SES. Further research is needed to uncover the nuances of bias, SES, and physician decision making throughout the patient care continuum and within various clinical environments.

Unifying Resident Education: 12 Interdisciplinary Critical Care Simulation Scenarios.

Introduction: Unified critical care training within residency education is a necessity. We created a simulation-based curriculum designed to educate residents on core topics and procedural skills, which crossed all adult disciplines caring for critically ill patients. Methods: Residents from seven adult disciplines participated in this annual program during intern year. Learners were grouped into mixed discipline cohorts. Each cohort attended three distinct 4-hour simulation-based sessions, each consisting of four scenarios followed by postevent debriefing. The curriculum included 12 total clinical scenarios. Scenarios covered a broad array of complex critical care topics facing all adult specialties and reinforced important system-specific initiatives. Assessments evaluated clinical performance metrics, self-reported confidence in curricular topics, procedural and communication skills, resident satisfaction, and interdisciplinary attitudes. Results: Quantitative and qualitative data analyzed in three published works over the past 9 years of curricular programming has demonstrated highly satisfied learners along with improved: clinical performance; self-reported confidence in clinical topics, procedural, and communication skills; and interdisciplinary collegiality. Discussion: Purposeful focus on curricular development that integrates basic, clinical, and procedural content, while promoting the development of interdisciplinary relationships and the practice of critical thinking skills, is vital for successful education and patient care. This curriculum was well received by interns, covered difficult to obtain GME milestones, and provided an opportunity for interdisciplinary education. In an era of limited time for devoted bedside teaching and variable training exposures to certain disease processes, the development and implementation of this curriculum has filled a void within our system for unified resident education.

Development and Empirical Testing of a Novel Team Leadership Assessment Measure: A Pilot Study Using Simulated and Live Patient Encounters.

BACKGROUND: Team leadership is critical to health care resuscitation team performance. There has been increased focus on competency in team leadership behaviors; however, there is still variability in how team leadership is assessed within emergency medicine. The objective of this study was to develop and pilot a novel team leadership assessment measure for emergency medicine resuscitation teams. METHODS: Team leadership dimensions and associated behaviors were identified through a systematic literature review and expert consensus. Included behaviors were used to create behaviorally anchored rating scales, which were then revised based on subject matter expert ratings. Four raters from three different academic institutions observed 30 video-recorded resuscitations (20 simulated and 10 actual patient care resuscitations). Mean leadership scores were calculated. Intraclass coefficients (ICCs) were calculated for each item and for overall leadership scores. Leader scores for the simulation-based scenarios were compared to external variables including level of training, team process, clinical performance, and team situational awareness. The study was conducted from July 2017 through June 2018. RESULTS: Leadership scores ranged from 2.23 to 4.30 (mean [±SD] = 3.18 [±0.50]). The ICC for the overall score was 0.79 for all observations, 0.87 for simulation-based observations, and 0.24 for the patient care observations. Team leadership scores on simulation-based observations did not correlate with available external variables. CONCLUSIONS: We developed a novel team leadership assessment measure for emergency medicine resuscitation teams with supporting validity evidence, including content validity and response process. The measure demonstrated acceptable inter-rater reliability when applied to simulation-based medical resuscitations; however, this did not translate to trauma resuscitations in the actual patient care setting.

A Mixed-methods Comparison of Participant and Observer Learner Roles in Simulation Education.

BACKGROUND: Traditional simulation-based education prioritizes participation in simulated scenarios. The educational impact of observation in simulation-based education compared with participation remains uncertain. Our objective was to compare the performances of observers and participants in a standardized simulation scenario. METHODS: We assessed learning differences between simulation-based scenario participation and observation using a convergent, parallel, quasi-experimental, mixed-methods study of 15 participants and 15 observers (N = 30). Fifteen first-year residents from six medical specialties were evaluated during a simulated scenario (cardiac arrest due to critical hyperkalemia). Evaluation included predefined critical actions and performance assessments. In the first exposure to the simulation scenario, participants and observers underwent a shared postevent debriefing with predetermined learning objectives. Three months later, a follow-up assessment using the same case scenario evaluated all 30 learners as participants. Wilcoxon signed rank and Wilcoxon rank sum tests were used to compare participants and observers at 3-month follow-up. In addition, we used case study methodology to explore the nature of learning for participants and observers. Data were triangulated using direct observations, reflective field notes, and a focus group. RESULTS: Quantitative data analysis comparing the learners' first and second exposure to the investigation scenario demonstrated participants' time to calcium administration as the only statistically significant difference between participant and observer roles (316 seconds vs. 200 seconds, p = 0.0004). Qualitative analysis revealed that both participation and observation improved learning, debriefing was an important component to learning, and debriefing closed the learning gap between observers and participants. CONCLUSIONS: Participants and observers had similar performances in simulation-based learning in an isolated scenario of cardiac arrest due to hyperkalemia. Findings support current limited literature that observation should not be underestimated as an important opportunity to enhance simulation-based education. When paired with postevent debriefing, scenario observers and participants may reap similar educational benefits.

ED endovaginal pelvic ultrasound in nonpregnant women with right lower quadrant pain.

INTRODUCTION: We hypothesized that emergency physician-performed endovaginal ultrasound (EVUS) would change diagnostic decision making in nonpregnant women with right lower quadrant (RLQ) pain. METHODS: A prospective cohort of female patients was enrolled at an urban emergency department (ED). Inclusion criteria were RLQ pain, hemodynamic stability, and a strong suspicion for appendicitis or right adnexal pathology. Treating physicians were queried regarding pre- and post-ED EVUS probability of disease, differential diagnoses, consultation, and management. Positive findings included large cysts or multitissue densities, tubal dilation, uterine enlargement/mass, and extensive peritoneal fluid. RESULTS: With a positive ED EVUS, mean physician probability increased for gynecologic (24%) and decreased for both surgical (14%) and medical (20%) disease. With a negative ED EVUS, mean physician probability increased for surgical disease (5.3%) and decreased for gynecologic disease (18.6%). CONCLUSION: Emergency department EVUS changes physician diagnostic decision making in nonpregnant women with undifferentiated RLQ pain.

Unifying interdisciplinary education: designing and implementing an intern simulation educational curriculum to increase confidence in critical care from PGY1 to PGY2.

BACKGROUND: A longitudinal, multidisciplinary critical care simulation curriculum was developed and implemented within a teaching hospital to address the need for consistent, safe, efficient, and unified critical care training within graduate medical education. Primary goals were to increase learner confidence in critical care topics and procedural skills across all specialties. Secondary goals included improving communication skills and obtaining a high level of learner satisfaction. All interns caring for adult patients within our hospital participated in three 4-h simulation-based sessions scheduled over the second half of their intern year. Pre- and postcurricular surveys evaluated self-confidence in critical care topics, procedures, and communication skills. The Debriefing Assessment for Simulation in Healthcare Student Version (DASH-SV) Short Form was used to evaluate facilitator debriefing. Data were compared with Wilcoxon rank sum and signed rank test. RESULTS: Pre- and postcurricular surveys were collected from 51 of 52 interns (98% response rate) in curricular year 1 and 59 of 59 interns (100% response rate) in curricular year 2 in six programs within the hospital. Resident confidence significantly improved in all areas (p < .05). DASH-SV demonstrated overall effective facilitator debriefing and > 75% of interns in both curricular years 1 and 2 expressed a desire for future educational sessions. CONCLUSIONS: The implemented curriculum increased learner confidence in select critical care topics, procedures, and communication skills and demonstrated a high level of learner satisfaction. The curriculum has expanded to learners from three other teaching hospitals within our system to unify critical care education for all interns caring for adult patients.

Supplemental oxygen use in ischemic stroke patients: does utilization correspond to need for oxygen therapy?

BACKGROUND: In 1994, the American Heart Association Stroke Council concluded that there were no data to support the routine use of supplemental oxygen in patients who had a stroke. More recently, supplemental oxygen has been suggested to be potentially detrimental. The purpose of this study was to determine the extent of oxygen use in ischemic stroke patients and whether patients receiving oxygen had indications for its use. METHODS: A literature search was performed to generate a comprehensive list of explicit criteria for supplemental oxygen use. When the literature disagreed, the criteria were included in the list to overestimate rather than underestimate the justification for oxygen use. A retrospective chart review of consecutive, nonintubated, ischemic stroke patients admitted to a university hospital was performed. Statistical tests and logistic regression models were constructed to identify the presence of unjustified oxygen use within the sample. Hospital charges were used to quantify opportunities for resource conservation. RESULTS: A total of 167 patient charts were reviewed yielding a total of 600 inpatient days abstracted. One hundred two patients (61.1%) received oxygen during some portion of their hospitalization. Of the 322 days that patients received oxygen, 147 (45.6%) met at least 1 criterion for oxygen use. Of the 278 days that patients did not receive oxygen, 69 (24.8%) met at least 1 of the criteria for oxygen use. There were 384 days for which no criteria were met. Of these, a patient still received oxygen 45.6% of the time (175 days). Factors associated with oxygen use included the presence of at least 1 justifying criteria as well as increasing age and male sex. Withholding oxygen from those not medically justified by the criteria could produce resource savings of roughly 45%. CONCLUSIONS: Using a literature-based list of criteria for supplemental oxygen use, only 45.6% of days of oxygen use were justified in our ischemic stroke population. This study demonstrates that oxygen therapy is commonly given to ischemic stroke patients without clear indication, and opportunities exist for substantial resource conservation.
