Presentation at the 2015 AAMC Health Workforce Research Conference

 

Overview

  • Expected increase in demand for healthcare services in the US
  • Physician supply may not be adequate to meet demand under traditional models of care
  • NPs and PAs might help fill service gaps in primary and specialty care, but estimates of this potential vary
  • Analyzed licensure data from the NC Health Professions Data System
  • Large growth in both professions led to larger numbers of NPs and PAs in most specialties
  • Specialty distributions changed over time for both NPs and PAs
  • NP proportions increased in medical subspecialties and decreased in pediatrics and Ob/Gyn
  • PA proportions decreased in primary care, increased in medical subspecialties, and were high in urgent care in 2013
  • What affects specialty distribution:
    • Supply: factors affecting individual provider specialty choice
    • Demand: factors inducing organizations to hire NPs/PA
  • NPs and PAs are a growing and flexible workforce available to meet emerging healthcare needs
  • Important similarities and differences between NPs and PAs should be considered in workforce design
  • Policies designed to affect specialty distribution of NPs and PAs should attend to both supply and demand factors
