Characteristics of primary care office visits to nurse practitioners, physician assistants and physicians in United States Veterans Health Administration facilities, 2005 to 2010: a retrospective cross-sectional analysis.
Abstract
UNLABELLED: BACKGROUND: Primary care, an essential determinant of health system equity,
efficiency, and effectiveness, is threatened by inadequate supply and distribution
of the provider workforce. The Veterans Health Administration (VHA) has been a frontrunner
in the use of nurse practitioners (NPs) and physician assistants (PAs). Evaluation
of the roles and impact of NPs and PAs in the VHA is critical to ensuring optimal
care for veterans and may inform best practices for use of PAs and NPs in other settings
around the world. The purpose of this study was to characterize the use of NPs and
PAs in VHA primary care and to examine whether their patients and patient care activities
were, on average, less medically complex than those of physicians. METHODS: This is
a retrospective cross-sectional analysis of administrative data from VHA primary care
encounters between 2005 and 2010. Patient and patient encounter characteristics were
compared across provider types (PA, NP, and physician). RESULTS: NPs and PAs attend
about 30% of all VHA primary care encounters. NPs, PAs, and physicians fill similar
roles in VHA primary care, but patients of PAs and NPs are slightly less complex than
those of physicians, and PAs attend a higher proportion of visits for the purpose
of determining eligibility for benefits. CONCLUSIONS: This study demonstrates that
a highly successful nationwide primary care system relies on NPs and PAs to provide
over one quarter of primary care visits, and that these visits are similar to those
of physicians with regard to patient and encounter characteristics. These findings
can inform health workforce solutions to physician shortages in the USA and around
the world. Future research should compare the quality and costs associated with various
combinations of providers and allocations of patient care work, and should elucidate
the approaches that maximize quality and efficiency.
