  • Title: Gaps in the supply of physicians, advance practice nurses, and physician assistants.
    Author: Sargen M, Hooker RS, Cooper RA.
    Journal: J Am Coll Surg; 2011 Jun; 212(6):991-9. PubMed ID: 21459629.
    Abstract:
    BACKGROUND: Based on the goals of health care reform, growth in the demand for health care will continue to increase the demand for physicians and, as physician shortages widen, advanced practice nurses (APNs) and physician assistants (PAs) will play larger roles. Together with physicians they constitute a workforce of "advanced clinicians." The objective of this study was to assess the capacity of this combined workforce to meet the future demand for clinical services. STUDY DESIGN: Projections were constructed to the year 2025 for the supply of physicians, APNs, and PAs, and these were compared with projections of the demand for advanced clinical services, based on federal estimates of future spending and historic relationships between spending and the health care labor force. RESULTS: If training programs for APNs and PAs grow as currently projected but physician residency programs are not further expanded, the aggregate per capita supply of advanced clinicians will remain close to its current level, which will be 20% less than the demand in 2025. Increasing the numbers of entry-level (PGY1) residents by 500 annually will narrow the gap, but it will remain >15%. CONCLUSIONS: The nation faces a substantial shortfall in its combined supply of physicians, APNs, and PAs, even under aggressive training scenarios, and deeper shortages if these scenarios are not achieved. Efforts must be made to expand the output of clinicians in all 3 disciplines, while also strengthening the infrastructure of clinical practice and facilitating the delegation of tasks to a broadened spectrum of caregivers in new models of care.
