Impact of an emergency medicine clerkship on students' perceptions of emergency medicine.

Purpose: To determine the impact of an emergency medicine (EM) clerkship on senior (4th year) medical students' perceptions of the EM specialty.

Subjects And Methods: This was a pre/posttest observational study in a mandatory 4-week EM clerkship. Students were anonymously surveyed pre- and postclerkship regarding perceptions of EM. The survey used 24 statements grouped across four domains: 1) student EM clerkship expectations/experiences, 2) perceptions regarding EM physicians, 3) perceptions regarding patients in the emergency department (ED), and 4) EM as a desirable career. Data were analyzed using paired-sample t-tests, and comparisons made using McNemar's χ (2) test.

Results: A total of 385 of 407 students (94.6%) completed the pre- and postclerkship survey. There was no significant difference between mean ratings before and after related to perceptions regarding EM physicians (3.71 versus 3.71), ED patients (3.80 versus 3.76), or EM as a desirable career (3.88 versus 3.84). However, ratings regarding clerkship expectations/experiences decreased (3.88 versus 3.56, P=0.001). Of the 292 students that ranked their top three specialties in both pre- and postclerkship surveys, 46 (16%) included EM as a top choice preclerkship, with 31 of these maintaining this interest postclerkship. Conversely, 12 students (5%) became interested in EM postclerkship. Some survey-statement ratings were influenced and varied by urban versus community clerkship-rotation site.

Conclusion: A mandatory senior EM clerkship did not significantly change overall students' perceptions regarding EM. Students with an interest in EM rated domains higher than those not interested, though there may have been an overall decline in perceptions related to clerkship expectations and experiences. Larger, multisite studies may help identify aspects of the field or EM clerkship that influence a student's ultimate career choice.
