Introduction. Hospital and emergency department closures are emblematic of America's changing healthcare delivery system, which often places rural vulnerable communities at further risk for poor health outcomes. Employing the Vulnerable Populations Conceptual Model (VPCM), we aimed to synthesize the existing research addressing care quality in these facilities and the impacts of their closures on affected communities and health status. Materials and Methods. We conducted a modified integrative literature review (outlined by Whittemore and Knafl), comparing and contrasting articles via an organizational matrix. We identified articles through three databases and ancestral searches. We included English-written, peer-reviewed articles published from 2010 forward. We excluded international and nonresearch articles that focused on the closure of specific departments (other than emergency departments). Our final sample included 26 primary research studies (24 quantitative and two qualitative). We scored the articles according to their scientific rigor and data relevance, then deductively coded them according to the VPCM constructs. Results. We identified two overarching themes from the literature: (1) association of rural hospital care and patient health outcomes and (2) access to hospital care-effects of closures and openings on rural vulnerable populations. Subthemes reflected access to care and other resources, relative risks associated with time-sensitive health events, and health outcomes. Discussion and Conclusion. We found that rural hospitals provide access to essential health services and emergency care in these vulnerable, underserved communities. Their loss may increase adverse outcomes in affected communities and the overall health system. However, our review was limited by the retrospective, nonexperimental nature of most included articles, and more data quantifying these effects and the impact of confounding factors are needed. Multidisciplinary stakeholders must jointly address declining access to hospital and emergency care by sustainably addressing social determinants of health, quality assurance, innovative healthcare delivery systems, and rural hospital funding.
