State of the National Emergency Department Workforce: Who Provides Care Where?

Abstract

Study objective: We describe the current US emergency medicine workforce in terms of clinician type and examine rural and urban emergency medicine workforce differences.

Methods: Using the 2014 Medicare Public Use Files, we performed a cross-sectional study of all clinicians receiving reimbursement for evaluation and management (E/M) services (levels 1 to 5) to Medicare fee-for-service Part B beneficiaries in the emergency department. Providers were defined as emergency physicians, nonemergency physicians, or advanced practice providers, corresponding with the Medicare Public Use Files data set. The primary outcome was the number of clinicians providing greater than 10 E/M claims tabulated as a distinct encounter. Urbanicity data were obtained from the National Bureau of Economic Research.

Results: Of 58,641 unique emergency medicine clinicians, 35,856 (61.1%) were classified as emergency physicians, 8,397 (14.3%) as nonemergency physicians, and 14,360 (24.5%) as advanced practice providers. Among nonemergency physicians categorized as emergency medicine clinicians, family practice and internal medicine predominated (41.7% and 19.9%, respectively). Among advanced practice providers, physician assistants (68.4%) and nurse practitioners (31.5%) predominated. A total of 58,565 emergency medicine clinicians were mapped to 2,291 US counties or equivalents. Urban counties had a higher proportion of emergency physicians (63.9%) compared with rural counties (44.8%); 27.1% of counties had no emergency medicine clinicians and 41.4% of counties had no emergency physicians reimbursed by Medicare fee-for-service Part B.

Conclusion: This work establishes a new baseline estimate of the emergency care workforce, encompassing nearly 60,000 emergency medicine clinicians, of whom fewer than 2 in 3 were emergency physicians. Notable differences exist in the type of clinician staffing of emergency care between urban and rural communities.
