Previously, Ghosh led the claims-based impact analysis for the evaluations of the Comprehensive Primary Care Initiative, the Independence at Home Demonstration, and the Program of All-Inclusive Care for the Elderly. In addition to U.S. health policy, he is interested in international development and population health issues.

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.
