Emergency ultrasound usage among recent emergency medicine residency graduates of a convenience sample of 14 residencies.

Background: Emergency Medicine (EM) residency graduates are trained to perform Emergency Medicine bedside ultrasound (EMBU). However, the degree to which they use this skill in their practice after graduation is unknown.
Objectives: We sought to test the amount and type of usage of EMBU among recent residency graduates, and how usage and barriers vary among various types of EM practice settings.
Methods: Graduates from 14 EM residency programs in 2003-2005 were surveyed on their current practice setting and use of EMBU.
Results: There were 252 (73%) graduates who completed the survey. Of the 73% of respondents reporting access to EMBU, 98% had used it within the past 3 months. Access to EMBU was higher in academic (97%) vs. community teaching (79%) vs. community non-teaching settings (62%) (p < 0.001), and in Emergency Departments (EDs) where yearly census exceeded 60,000 visits (87% vs. 65%, p < 0.001). Physicians in academic settings reported "high use" of EMBU more frequently than those in community settings for most modalities. FAST (focused assessment by sonography in trauma) was the most common high-use application and the most useful in practice. The greatest impediment to EMBU use was "not enough time" (61%).
Conclusions: Ultrasound usage among recent EM residency graduates is significantly higher in teaching than in community settings and in high-volume EDs. Its use is more widespread than in previous reports in all types of practice. There is a wide range of utilization of ultrasound in the various applications in emergency practice, with the evaluation of trauma being the most common.
