Objectives Provider efficiency has been reported in the literature but there is a lack of efficiency analysis among emergency medicine (EM) residents. We aim to compare efficiency of EM residents of different training levels and determine if EM resident efficiency is affected by emergency department (ED) crowding. Methods We conducted a single‐center retrospective observation study from July 1, 2014, to June 30, 2017. The number of new patients per resident per hour and provider‐to‐disposition (PTD) time of each patient were used as resident efficiency markers. A crowding score was assigned to each patient upon the patient's arrival to the ED. We compared efficiency among EM residents of different training levels under different ED crowding statuses. Dynamic efficiency changes were compared monthly through the entire academic year (July to next June). Results The study enrolled a total of 150,920 patients. A mean of 1.9 patients/hour was seen by PGY‐1 EM residents in comparison to 2.6 patients/hour by PGY‐2 and ‐3 EM residents. Median PTD was 2.8 hours in PGY‐1 EM residents versus 2.6 hours in PGY‐2 and ‐3 EM residents. There were no significant differences in acuity across all patients seen by EM residents. When crowded conditions existed, residency efficiency increased, but such changes were minimized when the ED became overcrowded. A linear increase of resident efficiency was observed only in PGY‐1 EM residents throughout the entire academic year. Conclusion Resident efficiency improved significantly only during their first year of EM training. This efficiency can be affected by ED crowding.
