Nurse Practitioner Work Environment and Rural Primary Care for Substance Use.

We examined the relationship between the nurse practitioner (NP) work environment and realized access (i.e., utilization) to primary care among rural older adults with substance use disorders (SUD). We analyzed cross-sectional NP survey data merged with Medicare claims and utilized fractional logistic regression. With one unit improvement in NP work environment, the odds of having older adults with SUDs in the practice increased by 20% (adjusted odds ratio=1.20, 95% confidence interval=1.01-1.44, p=0.04). Favorable work environments for NPs, including organizational support, collegiality, and role visibility, are associated with increased realized access to primary care among rural older adults with SUDs.
