Dr. Tracy L. Johnson, Ph.D., is Director of Health Care Reform Initiatives at Denver Health and Hospital Authority (DH) and Assistant Professor at the Colorado School of Public Health. She has more than 20 years of experience in health policy development, research, and evaluation. Her research spans the population health spectrum and includes health insurance coverage, population segmentation/risk stratification, delivery system design, health system financing and payment models, safety net provider issues, and health equity. In her current position, she advises DH on state and federal delivery system and payment reforms, designing and implementing its population segmentation strategy, and directing the evaluation of its $20 million Centers for Medicare and Medicaid Services (CMS) Health Care Innovation Award. The evaluation quantified the inpatient utilization and cost avoidance associated with a large-scale practice transformation effort to integrate population health approaches into the delivery of primary care services. Previously, Johnson served as owner and principal of Health Policy Solutions, Inc., a consulting firm specializing in strategic planning, health policy analysis, and health services research and evaluation. In that capacity, she advised the state agency that administers Medicaid and Child Health Plan Plus (CHP+) on programmatic and data-related issues. Johnson holds a Ph.D. in Health Policy from the Johns Hopkins Bloomberg School of Public Health.
