Shortages of primary care doctors are occurring globally; one means of
meeting this demand has been the use of physician assistants (PAs). Introduced
in the United States in the late 1960s to address doctor shortages, the PA
movement has grown to over 75,000 providers in 2011 and spread to Australia,
Canada, Great Britain, The Netherlands, Germany, Ghana, and South Africa. A
purposeful literature review was undertaken to assess the contribution of PAs to
primary care systems. Contemporary studies suggest that PAs can contribute to
the successful attainment of primary care functions, particularly the provision
of comprehensive care, accessibility, and accountability. Employing PAs seems a
reasonable strategy for providing primary care for diverse populations.
