Correlation of OSCE performance and point-of-care ultrasound scan numbers among a cohort of emergency medicine residents.

ABSTRACT: BACKGROUND:Point-of-care ultrasound (POCUS) is an important clinical tool for a growing number of medical specialties. The current American College of Emergency Physicians (ACEP) Ultrasound Guidelines recommend that trainees perform 150-300 ultrasound scans as part of POCUS training. We sought to assess the relationship between ultrasound scan numbers and performance on an ultrasound-focused observed structured clinical examination (OSCE). METHODS:This was a cross-sectional cohort study in which the number of ultrasound scans residents had previously performed were obtained from a prospective database and compared with their total score on an ultrasound OSCE. Ultrasound fellowship trained emergency physicians administered a previously published OSCE that consisted of standardized questions testing image acquisition and interpretation, ultrasound machine mechanics, patient positioning, and troubleshooting. Residents were observed while performing core applications including aorta, biliary, cardiac, deep vein thrombosis, Focused Assessment with Sonography in Trauma (FAST), pelvic, and thoracic ultrasound imaging. RESULTS:Twenty-nine postgraduate year (PGY)-3 and PGY-4 emergency medicine (EM) residents participated in the OSCE. The median OSCE score was 354 [interquartile range (IQR) 343-361] out of a total possible score of 370. Trainees had previously performed a median of 341 [IQR 289-409] total scans. Residents with more than 300 ultrasound scans had a median OSCE score of 355 [IQR 351-360], which was slightly higher than the median OSCE score of 342 [IQR 326-361] in the group with less than 300 total scans (p?=?0.04). Overall, a LOWESS curve demonstrated a positive association between scan numbers and OSCE scores with graphical review of the data suggesting a plateau effect. CONCLUSION:The results of this small single residency program study suggest a pattern of improvement in OSCE performance as scan numbers increased, with the appearance of a plateau effect around 300 scans. Further investigation of this correlation in diverse practice environments and within individual ultrasound modalities will be necessary to create generalizable recommendations for scan requirements as part of overall POCUS proficiency assessment.

Project description:BackgroundPoint-of-care ultrasound (POCUS) competence consists of image acquisition, image interpretation, and clinical integration. Limited data exist on POCUS usage patterns and clinical integration by emergency medicine (EM) residents. We sought to determine actual POCUS usage and clinical integration patterns by EM residents and to explore residents' perspectives on POCUS clinical integration.MethodsWe conducted an explanatory sequential mixed-methods study at a 4-year EM residency program. In phase 1, EM ultrasound (US) attendings observed PGY-4 EM residents' clinical integration of POCUS in real time while on shift in the emergency department (ED). EM US attendings evaluated residents on their intent to perform POCUS, actual POCUS usage, and competence per patient encounter. We used logistic regression to analyze these parameters. In phase 2, we conducted semi-structured interviews with the observed PGY-4 residents regarding POCUS usage and clinical integration in the ED. We analyzed qualitative data for themes.ResultsEmergency medicine US attendings observed 10 PGY-4 EM residents during 254 high-acuity patient encounters from December 2018 to March 2019. EM US attendings considered POCUS indicated for 26% (66/254) of patients, possibly indicated for 12% (30/254) and not indicated for 62% (158/254). Of the 66 patients for whom EM US attendings considered POCUS indicated, PGY-4s intended to perform POCUS for patient management 61% (40/66) of the time. PGY-4s subsequently incorporated POCUS into patient management 73% (48/66) of the time. EM US attendings considered PGY-4s entrustable to perform POCUS independently 81% (206/254) of the time. We did not find a statistically significant association between shift volume, shift type, or POCUS application, and resident intent to perform POCUS nor competence. Interviews identified three factors that influence PGY-4's POCUS clinical integration: motivations to use POCUS, barriers to utilization, and POCUS educational methods.ConclusionsThis mixed-methods study identified a significant gap in POCUS utilization and clinical integration by PGY-4 EM residents for clinically indicated cases identified by EM US attendings. As clinical integration is a cornerstone of POCUS competence, it is important to ensure that EM resident POCUS curricula emphasize training on clinical utilization and indications for POCUS while on shift in the ED.

Project description:ObjectivesThe primary objective was to survey pediatric emergency medicine (PEM) leaders and fellows regarding point-of-care ultrasound (POCUS) training in PEM fellowship programs, including teaching methods, training requirements, and applications taught. Secondary objectives were to compare fellows' and program leaders' perceptions of fellow POCUS competency and training barriers.MethodsThis was a cross-sectional survey of U.S. PEM fellows and fellowship program leaders of the 78 fellowship programs using two online group-specific surveys exploring five domains: program demographics; training strategies and requirements; perceived competency; barriers, strengths, and weaknesses of POCUS training; and POCUS satisfaction.ResultsEighty-three percent (65/78) of programs and 53% (298/558) of fellows responded. All participating PEM fellowship programs included POCUS training in their curriculum. Among the 65 programs, 97% of programs and 92% of programs utilized didactics and supervised scanning shifts as educational techniques, respectively. Sixty percent of programs integrated numerical benchmarks and 49% of programs incorporated real-time, hands-on demonstration as training requirements. Of the 19 POCUS applications deemed in the literature as core requirements for fellows, at least 75% of the 298 fellows reported training in 13 of those applications. Although less than half of fellows endorsed competency for identifying intussusception, ultrasound-guided pericardiocentesis, and transvaginal pregnancy evaluation, a higher proportion of leaders reported fellows as competent for these applications (40% vs. 68%, p ≤ 0.001; 21% vs. 39%, p = 0.003; and 21% vs. 43%, p ≤ 0.001). Forty-six percent of fellows endorsed a lack of PEM POCUS evidence as a training barrier compared to 31% of leaders (p = 0.02), and 39% of leaders endorsed a lack of local financial support as a training barrier compared to 23% of fellows (p = 0.01).ConclusionsAlthough most PEM fellowship programs provide POCUS training, there is variation in content and requirements. Training does conform to many of the expert recommended guidelines; however, there are some discrepancies and perceived barriers to POCUS training remain.

Project description:BackgroundThe majority of children in the United States seek emergency care at community-based general emergency departments (GEDs); however, the quality of GED pediatric emergency care varies widely. This may be explained by a number of factors, including residency training environments and postgraduate knowledge decay. Emergency medicine (EM) residents train in academic pediatric EDs, but didactic and clinical experience vary widely between programs, and little is known about the pediatric skills of these EM residents. This study aimed to assess the performance of senior EM residents in treating simulated pediatric patients at the end of their training.MethodsThis was a prospective, cross-sectional, simulation-based cohort study assessing the simulated performance of senior EM resident physicians from two Massachusetts programs leading medical teams caring for three critically ill patients. Sessions were video recorded and scored separately by three reviewers using a previously published simulation assessment tool. Self-efficacy surveys were completed prior to each session. The primary outcome was a median total performance score (TPS), calculated by the mean of individualized domain scores (IDS) for each case. Each IDS was calculated as a percentage of items performed on a checklist-based instrument.ResultsA total of 18 EM resident physicians participated (PGY-3 = 8, PGY-4 = 10). Median TPS for the cohort was 61% (IQR = 56%-70%). Median IDSs by case were as follows: sepsis 67% (IQR = 50%-67%), seizure 67% (IQR = 50%-83%), and cardiac arrest 67% (IQR = 43%-70%). The overall cohort self-efficacy for pediatric EM (PEM) was 64% (IQR = 60%-70%).ConclusionsThis study has begun the process of benchmarking clinical performance of graduating EM resident physicians. Overall, the EM resident cohort in this study performed similar to prior GED teams. Self-efficacy related to PEM correlated well with performance, with the exception of knowledge relative to intravenous fluid and vasopressor administration in pediatric septic shock. A significant area of discrepancy and missed checklist items were those related to cardiopulmonary resuscitation and basic life support maneuvers.
