OverviewAI-generated summary
Brigham Walker's research investigates health outcomes and disparities, particularly within the context of public health programs and the COVID-19 pandemic. His work examines the impact of Medicaid expansion on uncompensated care costs and medical debt in Louisiana, and the disparities in telemedicine use among Louisiana Medicaid beneficiaries during the COVID-19 pandemic. Walker has also studied the associations between government spending and pregnancy-related mortality in the U.S. and the mediators of discrimination in primary care appointment access.
His publications include comparisons of real-world time-to-event endpoints in oncology research and telehealth outcomes for Type 2 diabetes care among Medicare beneficiaries. Walker's scholarship metrics include an h-index of 11, with 75 total publications and 389 total citations. He has collaborated with Roberto J. Bravo at the University of Arkansas for Medical Sciences on shared publications.
