Primary care gap: factors associated with persistent lack of primary care after hospitalisation.

Abstract

IntroductionAccess to primary care in the USA is associated with decreased acute care utilisation and better health outcomes, yet millions of Americans lack a primary care provider (PCP). In our study, we report the risk factors for having no assigned PCP for hospitalised patients both at the time of discharge and over the course of the following year.MethodsWe conducted a retrospective cohort study of 12 663 adult patients discharged from the medicine service at our academic inpatient hospital from 2017 to 2018. We compared the characteristics of patients with and without a PCP listed in the electronic health record at time of discharge. In a second analysis, for those patients without a PCP, we used subsequent encounters with our health system to compare characteristics of those who had a PCP assigned within 1 year after discharge with those who did not.ResultsAt time of discharge, patients without a PCP were more likely to be younger, male, non-Asian and non-Black, to have Medicaid insurance or to be self-pay, to be experiencing homelessness and to have a substance use disorder diagnosis. During the year after discharge, the most significant risk factors for persistently lacking a PCP were non-private insurance status (Medicaid, Medicare, self-pay), experiencing homelessness and having a substance use disorder diagnosis.DiscussionOur study demonstrates important risk factors for persistently lacking an assigned PCP in our urban patient population, including health insurance status, homelessness and substance use disorders. Targeted interventions are indicated to connect these high-risk individuals to primary care.
