Research Interest: Primary Care Research

Dr. Tapp's main research interest is to study healthcare delivery to underserved populations in Charlotte, NC. As one of the research team members of MAPPR, The Mecklenburg Area Partnership for Primary Care Research, she develop research projects with a group of primary care practices devoted principally to the primary care of patients, but also with a mission to investigate questions related to community-based practice and how to improve the quality of primary care by enhancing the translation of research findings back into practice. The primary goal of this network is to address disparities in healthcare access by developing and implementing interventions that increase the efficacy of healthcare delivery for underserved populations. The methods we use involve an emerging model of research is known as Community based participatory research (CBPR), and involves using key stake holders, including medical professionals, community members and patients as research partners. In one study, we compared the effectiveness of five different systems that provide primary care services for the uninsured Hispanic population in Charlotte. All service providers are members of MAPPR, and include hospital-based clinics, free clinics, low-overhead clinics, and the emergency department. We determined the effectiveness of each system based on travel distance, costs, and patient satisfaction. Travel distance was measured using geospatial modeling. The cost of services at each location was determined using direct cost and patient charge data. Patient satisfaction was measured using a standardized, validated patient survey. Participatory techniques allowed providers from each system to provide input about the research process. Focus groups with the providers were used to gather information about their experiences providing care for uninsured Hispanic patients and also to involve the clinic representatives as research partners and use their expertise to ensure that recommendations that flow from the study were relevant, applicable and feasible for the clinics/centers. These focus groups provided an opportunity to share the results obtained and to work with the participating clinics to determine how those results can best be organized, disseminated and applied, ensuring that the research undertaken is directly applicable and informed by all stakeholders.
