Prevalence and Practice Characteristics of Advanced Practice Providers in Upper-Extremity Surgery, 2013-2021.

PURPOSE

This study evaluated the prevalence, characteristics, and reimbursement of advanced practice providers, including nurse practitioners and physician assistants, who provide care related to the diagnosis and treatment of diseases and conditions of the hand, wrist, and upper extremities in the United States from 2013 to 2021.

METHODS

Our analysis was a retrospective cohort study evaluating the diagnostic, procedural, and therapeutic services provided by advanced practice providers from 2013 to 2021 using the Medicare Provider Utilization and Payment Data Public Use Files from the Centers for Medicare and Medicare Services. The reported provider type and billing codes were used to identify health care professionals providing upper-extremity care such as ordering radiographs, applying casts and splints, and performing procedures on the hand, wrist, or other anatomic regions of the upper extremity. Trends over the study period and available data about services provided were analyzed.

RESULTS

From 2013 to 2021, providers of upper-extremity care included 19,525 (64.7%) doctor of medicine or doctor of osteopathic medicine upper-extremity surgeons, 7,612 (25.2%) physician assistants, and 3,042 (10.1%) nurse practitioners. The nonsurgeon providers were more likely to be women and provide care in micropolitan areas with less than 50,000 people compared with upper-extremity surgeons. Overall, the number of advanced practice providers who billed for upper-extremity care increased by 170.9% from 1,965 in 2013 to 5,324 in 2021. Based on these trends, the growth of APPs providing upper-extremity care is expected to continue.

CONCLUSIONS

There is a growing prevalence of advanced practice providers in upper-extremity care, and this trend is expected to continue.

CLINICAL RELEVANCE

With a growing need for upper-extremity care and predicted shortages in the surgeon workforce, the scope of practice and integration of advanced practice providers merits further discussion and evaluation.
