I serve as Professor in the Department of Medical Social Sciences at Northwestern University Feinberg School of Medicine. Following a residency in Preventive Medicine, I completed a fellowship in Health Services Research emphasizing large database design and analysis and inter-disciplinary chronic care models. This training laid the foundation for a career in quality improvement (Medical Director for Quality) and outcomes research. I serve as Principal Investigator of FORCE-TJR, a P50 (AHRQ) for comparative effectiveness research in total joint replacement (TJR) outcomes. This national effort enrolled over 30,000 TJR patients from 200 orthopedists to determine best practices to achieve optimal pain relief and physical function for adults with knee and hip arthritis. Annual patient-reported outcomes (PROs), adverse events, and revision data will be collected indefinitely from this longitudinal research cohort. FORCE-TJR returns real-time individual and aggregate trended PRO and risk data to sites to foster a learning health system. In addition, a PCORI-funded cluster randomized trial (6000 patients; 30 surgeons) is evaluating the role of PRO-based, tailored predictive data in a shared decision tool to guide TJR decisions. Other research includes evaluation of physical therapy, alternate anti-thrombotic medications, and opioid use on TJR outcomes.
