Janet Prvu Bettger
Associate Professor of Orthopaedic Surgery

Dr. Bettger’s research is dedicated to establishing real world evidence aimed to improve health care quality and policies that reduce the burden of disease and disability. As a health services researcher and implementation scientist, her research extends from observational studies to randomized and pragmatic trials. She is currently principal investigator for the VERITAS implementation-effectiveness RCT of a physical therapist supported virtual care management strategy for exercise at home after total knee replacement. In addition to VERITAS, she has examined implementation of several integrated care models to improve the transition home from the hospital (COMPASS for stroke, RECOVER for stroke in rural China, and co-PI on a R21 for trauma patients in Tanzania). She also studies implementation of community-based models of care that can prevent functional decline. These include the CTSA-funded IMPAC RCT of integrating physical therapists into primary care as first line providers to address musculoskeletal pain, the VA-funded Gerofit program of structured and progressive exercise for older Veterans, MRC-funded SINEMA RCT of a village-based model supporting stroke recovery in China, NHLBI-funded sickle cell care, and a NIDCD study comparing three primary care protocols for older adult hearing healthcare.

In addition to the evidence translation studies in China (RECOVER and SINEMA) and Tanzania, she has partnered with experts in Singapore on stroke systems research, and worked on large cluster randomized trials to improve evidence-based care in Brazil, Peru, Argentina (BRIDGE-Stroke) and China (CNSR and Golden Bridge). To address health locally, she is the faculty sponsor for Exercise is Medicine at Duke and for Help Desk, a student volunteer community resource navigator model addressing social determinants of health.

Dr. Bettger received her BA from the University of Western Ontario, Canada and her MS from the University of Wisconsin–LaCrosse where she studied community reintegration for stroke and brain-injured patients transitioning from hospital to home. Her doctoral training in Rehabilitation Sciences, completed at Boston University, concluded with an investigation of patterns of functional recovery and factors affecting outcomes in patients transitioning home following acute rehabilitation. While working on her doctorate, she also worked in state government as the director of the Paul Coverdell National Acute Stroke Registry. Dr. Bettger completed post-doctoral training at the University of Pennsylvania with a NIH NRSA research fellowship in neurorehabilitation, a research fellowship at the NewCourtland Center for Transitions and Health, and a Switzer Fellowship funded by the National Institute on Disability and Rehabilitation Research to study the role of the environment on functional outcomes. She completed additional research training at Duke as a mentored scholar in comparative effectiveness research funded by AHRQ. She is currently an Associate Professor and the Director of Health Policy and Implementation Science for Duke's Department of Orthopaedics. She has a secondary appointment in the Duke University School of Nursing, is affiliate faculty with the Duke Clinical Research Institute (DCRI) and Duke Global Health Institute (DGHI), a Senior Fellow of the Duke Center for the Study of Aging and Human Development, and is a Fellow of the American Heart Association. She is the Co-Director of the Duke Clinical and Translational Institute (CTSA) Pilots Accelerator Core and the Director of Undergraduate Initiatives for the Duke-Margolis Center for Health Policy.
