Study objective: We explore the variation in physician- and hospital-level admission rates in a group of emergency physicians in a single health system. Methods: This was a cross-sectional study that used retrospective data during various periods (2005 to 2010) to determine the variation in admission rates among emergency physicians from 3 emergency departments (EDs) within the same health system. Patients who left without being seen or left against medical advice, patients treated in fast-track departments, patients with primary psychiatric complaints, and those younger than 18 years were excluded, as were physicians with fewer than 500 ED encounters during the study period. Emergency physician-level and hospital-level admission rates were estimated with hierarchic logistic regression, which adjusted for patient age, sex, race, chief complaint, arrival mode, and arrival day and time. Results: A total of 389,120 ED visits were included in the analysis, and patients were treated by 89 attending emergency physicians. After adjusting for patient and clinical characteristics, the hospital-level admission rate varied from 27% to 41%. At the physician level, admission rates varied from 21% to 49%. Conclusion: There was 2.3-fold variation in emergency physician adjusted admission rates and 1.7-fold variation at the hospital level. In the new era of cost containment, wide variation in this common, costly decision requires further exploration. © 2013 American College of Emergency Physicians.
