​Health plan/health system description Harvard Pilgrim Health Care (HPHC) is a non-profit regional health plan operating in Massachusetts, Maine, New Hampshire, and Connecticut that is currently providing medical insurance or administering insurance benefits for over 2.7 million members; over 80% of members also have full pharmacy coverage. The HPHC provider network comprises nearly 9,000 primary care providers (general internists or family practitioners) and 18,000 specialist physicians who practice in a broad range of settings. HPHC maintains an administrative data warehouse that is used for both operational management and research. Enrollment and administrative claims data are available for HPHC members from 2000 to present. Linked electronic medical record data are available for about 13% of the HPHC member population.
Collaboration requirements and additional information HPHC’s research policies require that every research program administered at HPHC or that uses HPHC data to study HPHC members must have a local Principal Investigator who is a faculty member of Harvard Pilgrim Health Care Institute or a professional staff member of another HPHC department.
Research capabilities The Harvard Pilgrim Health Care Institute (HPHCI) houses the Department of Population Medicine (DPM) of Harvard Medical School. DPM is the nation's only medical school appointing department co-sponsored by a health plan. DPM comprises Harvard Medical School-appointed faculty members, doctoral and clinical research fellows, and staff. DPM also hosts a range of graduate and post-graduate research fellows.

Areas of strength of DPM’s research program include: child health, obesity and its prevention, drug policy (domestic and international), safety and effectiveness of drugs and vaccines, medical ethics, diffusion of electronic medical records, quality improvement for chronic disease treatment and prevention, and population-based systems for monitoring infectious diseases.
