AbstractBackground: Arthrocentesis of the ankle and elbow and brachial plexus nerve blocks are infrequently performed procedures; however, clinicians in specialties such as emergency medicine are required to be proficient in these procedures in the event of emergent or urgent necessity. Objectives: The objective of this study was to create, implement, and assess a fresh cadaver-based educational model to help resident physicians learn how to perform ultrasound-guided arthrocentesis of the ankle and elbow and ultrasound-guided regional nerve blocks. Methods: This was a single-center cross-sectional study conducted at an academic medical center. After a brief didactic session, 26 emergency medicine residents with varying levels of clinical and ultrasound experience rotated through 4 fresh cadaver-based stations. The objective of each station was to understand the sonographic anatomy and to perform ultrasound-guided arthrocentesis or regional nerve block with hands-on feedback from ultrasound fellows and faculty. Participants were subsequently asked to complete a questionnaire which evaluated participants' experience level, opinions, and procedural confidence regarding the 4 stations. Results: A total of 26 residents participated in this study. All 26 residents agreed that the cadaver model (compared with clinical anatomy) was realistic regarding ultrasound quality of the joint space, ultrasound quality of the joint effusion, ultrasound quality of nerves, tissue density, needle guidance, and artifacts. Finally, there was a statistically significant difference between mean scores for pre-simulation and post-simulation session participant procedural confidence for all 4 procedures. Conclusions: This fresh cadaver-based ultrasound-guided educational model was an engaging and well-received opportunity for residents to gain proficiency and statistically significant confidence in procedures which are uncommonly performed in clinical settings.

MODIFICATION OF A DIAGNOSTIC ULTRASOUND UNIT'S MOVEMENT SYSTEM TO PERFORM SCANNING DURING FOCUSSED, ULTRASOUND HYPERTHERMIA.Anhalt, Dennis Paul, 1960- (The University of Arizona., 1986)
Multimodular Ultrasound Orientation: Residents' Confidence and Skill in Performing Point-of-care UltrasoundStolz, Lori A; Amini, Richard; Situ-LaCasse, Elaine; Acuña, Josie; Irving, Steven C; Friedman, Lucas; Fiorello, Albert B; Stea, Nicholas; Fan, Heinrich; Adhikari, Srikar; et al. (CUREUS INC, 2018-11-15)Introduction The objectives of this study were to determine if a multimodular introductory ultrasound course improved emergency medicine intern confidence in performing a point-of-care ultrasound and if our educational objectives could be met with our chosen structure. Methods This is a prospective, observational study evaluating three consecutive incoming emergency medicine residency classes from three residency programs. A one-day introductory ultrasound course was delivered. The course consisted of 1) flipped classroom didactics, 2) in-person, case-based interactive teaching sessions, and 3) check-listed, goal-driven, hands-on instruction. Results Over three years, 73 residents participated in this study. There was no significant difference in performance on the written test (p = 0.54) or the skills assessment (p = 0.16) between years. Performance on the written pre-test was not a predictor of performance on the skills test (R2 = 0.028; p = 0.19). Prior to training, residents were most confident in performing a focused assessment with sonography for trauma examination (median confidence 5.5 (interquartile range (IQR): 3 - 7) on a 10-point Likert scale where 1 represents low confidence and 10 represents high confidence). They reported the lowest confidence in performing a cardiac ultrasound (3 (IQR: 2 - 6)). Following training, residents reported increased confidence with all applications (p < 0.001). Eighty-five percent (confidence interval (CI): 73, 92) of residents agreed that the online ultrasound lectures effectively teach point-of-care ultrasound applications and 98% (CI: 88, 100) agreed that case-based interactive sessions helped them understand how ultrasound changes the management of acutely ill patients. Conclusions A written test of knowledge regarding the use of point-of-care ultrasound does not correlate with procedural skills at the start of residency, suggesting that teaching and evaluation of both types of skills are necessary. Following a multimodular introductory ultrasound course, residents showed increased confidence in performing the seven basic ultrasound applications. Residents reported that an asynchronous curriculum and case-based interactive sessions met the learning objectives and effectively taught point-of-care ultrasound applications.
