Comparing Resident Procedures in Rural Versus Urban Emergency Departments

Rural rotations can be a valuable experience for emergency medicine (EM) residents. To date, there has not been a retrospective cohort study comparing procedures performed at urban versus rural emergency departments (EDs).

The purpose of this study was to compare procedures performed by EM residents in urban versus rural EDs, with the hypothesis that there will be no significant difference in the procedures performed.

A retrospective cohort study was conducted comparing procedures performed by second- and third-year EM residents based on medical chart review. The procedures were counted at three locations in West Virginia, including a small rural ED, a large rural ED, and a tertiary care ED. Procedure notes were collected from September 2018 to September 2019. The final analysis included nine months, as three months did not have residents at all locations. Eight procedures were standardized based on the number of procedures performed per 100 hours worked by residents. A comparison of total procedures and complex versus simple procedures was performed. A Kruskal-Wallis H test was performed to compare resident hours for procedures between each of the three locations. To compare each of the hospitals to one another separately, Mann-Whitney U tests were performed.

The total resident hours worked included 1,800 at the small rural ED, 13,725.5 at the tertiary care ED, and 5,319 at the large rural ED. A p-value of 0.0311 for the Kruskal-Wallis H Test indicated a difference between at least two of the ED sites. A statistically significant difference exists (p-value = 0.0135) between the urban ED (95% CI: 0.15-0.62) and the large rural ED (95% CI: 0.54-1.53). There was no significant difference in complex versus simple procedures among the three locations (p-value = 0.4159).

When compared with the tertiary care ED, residents performed more total procedures at the large rural ED and similar total procedure numbers at the small rural ED when standardized for hours worked. There was no significant difference when comparing complex and simple procedures among the three locations.
