OverviewAI-generated summary
John M. Westfall's research has focused on primary health care delivery in the United States, with a particular emphasis on the integration of behavioral health services and the impact of telehealth. His work has investigated the capacity of primary care to adopt telehealth technologies and compared the quality of care received through in-person versus telemedicine visits within large health systems.
Westfall has also examined the role of primary care in public health initiatives, including vaccination programs and the potential contributions to COVID-19 immunization efforts. His publications address the financial implications of the COVID-19 pandemic on primary care practices and the broader revitalization of the U.S. primary care infrastructure. He has also studied the effect of the COVID-19 pandemic on mental health visits within primary care settings across multiple countries.
His scholarship metrics include an h-index of 32, with 212 total publications and 4,553 total citations. Key collaborators include William Ventres, Leslie A. Stone, Arthur Kaufman from the University of Arkansas for Medical Sciences, and Sharon Reece from the University of Arkansas at Fayetteville.
