Abstract
BackgroundBy 2025, experts estimate a significant shortage of primary care providers in the United States, and expansion of the nurse practitioner (NP) workforce may reduce this burden. However, barriers imposed by state NP regulations could reduce access to primary care. PurposeThe objectives of this study were to examine the association between three levels of NP state practice regulation (independent, minimum restrictive, and most restrictive) and the proportion of the population with a greater than 30-min travel time to a primary care provider using geocoding. MethodsLogistic regression models were conducted to calculate the adjusted odds of having a greater than 30-min drive time. FindingsCompared with the most restrictive NP states, states with independent practice had 19.2% lower odds (p = .001) of a greater than 30-min drive to the closest primary care provider. DiscussionAllowing NPs full autonomy to practice may be a relatively simple policy mechanism for states to improve access to primary care.
