Utilization of point-of-care ultrasound among graduates of a 4-year longitudinal medical school ultrasound curriculum

Abstract

Objective In 2011, School of Medicine, University of California, Irvine was among the first schools to implement a 4-year ultrasound curriculum. We aimed to find the point-of-care ultrasound (POCUS) utilization pattern among University of California, Irvine alumni.Methods We surveyed University of California, Irvine alumni from the class of 2011 and beyond. Survey questions included POCUS reliance, frequency of use, and comfort with image acquisition and interpretation compared with peers. The primary outcomes were self-reported comfort and reliance on POCUS.Results We received 93 responses from 624 surveyed alumni (response rate, 14.9%), of which 87 were analyzed. Although 46 respondents (52.9%) reported more reliance on POCUS, three (3.4%) relied on it less than their peers. At the same time, 72 (82.7%) and 67 (77.0%) felt more comfortable than their colleagues in obtaining and interpreting POCUS, respectively. No respondents felt less comfortable obtaining or interpreting POCUS than their peers. The frequency of POCUS use correlated directly with the frequency with which POCUS changed the responder’s case management (rho, 0.860; P<0.001). POCUS reliance also correlated with respondents’ comfort level in obtaining (rho, 0.321; P<0.001) and interpreting (rho, 0.378; P<0.001) POCUS results.Conclusion University of California, Irvine graduates had higher reliance on POCUS than peers in their respective specialties. Their POCUS findings frequently changed their case management.
