Item The Effects of Healthcare Service Disruptions on the Community, Healthcare Services and Access to Care(2022-08) Mills, Carol Ann; Blackburn, Justin; Holmes, Ann M.; Unroe, Kathleen; Yeager, Valerie A.Access to healthcare services is important for improving health outcomes, preventing and managing illness, and achieving health equity. The geographic maldistribution of physicians has a negative impact on rural areas compared to urban, particularly as it relates to access to healthcare. Rural hospitals have been closing or converting to another form of healthcare service at an increasing rate, adding another element to the existing complexities in rural access to care. Although a hospital closure in any location may have a considerable impact on the community, the closure of a rural hospital may have disproportionately more substantial implications for the economy and employment, health outcomes, and access to care. The contributing factors preceding rural hospital closures have been studied, but less is known about the full impact of rural hospital closures on the community. There is some evidence of shortages in healthcare providers and services, and therefore communities may employ multiple strategies to mitigate the shortages and provide services, including utilizing telehealth/virtual services. This dissertation proposes to examine the effects of rural hospital closures on the community, healthcare services, access to care, and provide a qualitative assessment of telehealth as a strategy to bridge gaps in provider access. This dissertation includes three studies: 1) a systematic review of the literature to examine the impact of rural hospital closures on the community; 2) an empirical study that utilizes a generalized difference in difference design with county and year fixed effects to estimate the relationship between rural hospital closures and nursing homes; and 3) a qualitative study exploring the perceptions and experiences of the nurses that piloted a virtual care support project, providing insights into crucial elements important to the implementation of similar models and the role of telehealth in bridging healthcare workforce gaps.Item Examining the Impact of State-Mandated Insurance Benefits and Reimbursement Provisions on Access to Diabetes Self-Management Education and Training (DSME/T)(2019-09) Brown-Podgorski, Brittany L.; Vest, Joshua R.; deGroot, Mary K.; Holmes, Ann M.; Shi, Yunfeng; Simon, Kosali I.With an estimated 30.2 million diagnosed and undiagnosed cases among adults (and another 84 million at risk), diabetes mellitus is one of the most prevalent chronic conditions and a leading cause of mortality in the US. Diabetes self-management education and training (DSME/T) is a recognized standard of care and provides patients with the requisite knowledge and skills to properly manage the condition, improve long-term health outcomes, and reduce health care expenditures. Yet, DSME/T is greatly underutilized. Health insurance coverage that does not include benefits for DSME/T effectively imposes barriers to access for patients in need of the service. Many states have adopted laws and regulations requiring public and/or private insurers in their market to provide benefits for DSME/T; however, these requirements vary by state. It is unclear if these policies effectively improve access to DSME/T services. This dissertation seeks to rigorously assess the impact of state-mandated benefits and reimbursement provisions on access to DSME/T among adult patients with diabetes. The first analysis utilizes a unique combination of legal and programmatic data to quantify changes in the supply of DSME/T resources after the adoption of state-mandated benefits (potential access). The second analysis merges legal data with the Medical Expenditure Panel Survey (MEPS) from 2008 to 2016 to examine the impact of state mandates and reimbursement provisions on patient utilization of DSME/T (realized access). Lastly, the final analysis utilizes electronic health record data (2010-2016) from a safety net population to determine if patients’ evaluated need for DSME/T predicts the likelihood of receiving a DSME/T referral during a provider encounter (equitable access). Using novel data sources and a sophisticated policy analysis technique, this study provides a rigorous assessment of the impact of decades of state policies designed to improve access to care.Item Nurse practitioner patient care patterns and practice characteristics : understanding the role of state scope-of-practice policies(2017-05-09) Norwood, Connor W.; Harle, Christopher; Menachemi, Nir; Stone, Cynthia; Liu, ZiyueIntroduction: The U.S. is faced with a primary care (PC) workforce shortage; an estimated 43 percent of the population has unmet health care needs and 18.2 percent of the adult population lacks a usual source of care (USC) provider. The workforce shortage limits even those with a USC from receiving the full scope of recommended clinical services. One promising solution is reforming scope-of-practice (SOP) policies for PC nurse practitioners (NPs). Objectives: The primary objective of this dissertation was to assess the impact of NP SOP policy implementation on NP practice patterns and patient access to PC by evaluating NP time spent delivering patient care, NP role as USC providers, patient travel times, and appointment availability. Methods: The studies discussed in this dissertation leveraged cross-sectional data from the National Sample Survey of Nurse Practitioners (NSSNP), time-series data from the Medical Expenditure Panel Survey (MEPS), and the Nurse Practitioner Professional Practice Index (NPPPI) to quantify variations in state policy environments. We used generalized mixed effects models to examine relationships in the cross-sectional data analyses and two-way fixed effect models to evaluate longitudinal data. Results: Our analyses revealed several key findings: NP SOP policies do impact the percentage of time NPs spend providing direct patient care; the NP workforce role as USC providers has increased as SOP policies have changed; states with supportive reimbursement policies have more NPs working as USC providers; and states with fewer NP supervision requirements have shorter patient travel times to USC providers. Conclusion: The U.S. health care system must continue to evolve to address the growing demand for PC services. While strategies to increase the supply of PC providers may be an effective long-term solution, our findings suggest that NP SOP reform may be a viable and complementary strategy to increasing the capacity of the PC workforce, providing more immediate relief.
