About Deborah

Deborah Peikes has technical and substantive expertise in studying how to improve the delivery of primary care through the patient-centered medical home and related models of care; value-based purchasing; care coordination and disease management for people with chronic illnesses; and the health, employment, and social integration of beneficiaries with severe disabilities.

Peikes currently leads a large-scale, mixed-methods evaluation of the Comprehensive Primary Care Plus, a multipayer initiative to improve care delivery in thousands of primary care practices, for the Centers for Medicare & Medicaid Services (CMS). She led the evaluation of the Comprehensive Primary Care initiative, an earlier intervention to transform primary care delivery and payment. Peikes has led a series of studies on medical homes and quality improvement for the Agency for Healthcare Research and Quality, and evaluations of care coordination for CMS. She has also conducted studies of health policies and programs for the Robert Wood Johnson Foundation, the Medicare Chronic Care Practice Research Network, Aetna, United, the United Auto Workers, and the Health Resources and Services Administration. In addition, Peikes played a lead role in evaluating the effect of health care and employment supports provided by the Social Security Administration to beneficiaries with disabilities. For one of those projects, she directed an evaluation of the State Partnership Initiative, which tested employment supports and benefits counseling in 12 states.

Peikes has published widely about primary care, care coordination, and disability policy, including in the Journal of the American Medical Association (JAMA), Health Affairs, New England Journal of Medicine, Health Services Research, and the American Journal of Managed Care. Peikes was the first author of an article on the effects of care coordination on Medicare beneficiaries in JAMA that was awarded Best Paper by both AcademyHealth and the National Institute for Health Care Management. She also serves on the editorial board of Medical Home News.

Peikes has taught a graduate class on program evaluation at Princeton University’s Woodrow Wilson School of Public and International Affairs. She holds an M.P.A. in economic policy and a Ph.D. in public policy from Princeton University, and she was a Fulbright Scholar.

Key Projects
  • Evaluation of the Comprehensive Primary Care Initiative

    Mathematica and its partner, Group Health Cooperative, evaluated the effects of CPC on cost, quality, utilization, and patient and provider experience. We also provided rapid cycle (quarterly) feedback to participating practices, CMS, and CMS’s regional partners.

  • Medicare Coordinated Care Demonstration

    Mathematica tested whether care coordination and disease management programs in the fee-for-service setting lower Medicare expenditures, or increase the quality of health care services and beneficiary and provider satisfaction without increasing expenditures for beneficiaries with chronic illnesses....
