Health and Homelessness Data Sharing Community of Practice

2026

Connecting for Better Health, Homebase, and Georgetown University’s Massive Data Institute have developed the Health and Homelessness Community of Practice (CoP). The CoP brings together Continuums of Care (CoCs), Medi-Cal Managed Care Plans (MCPs), and their partners to address data matching and sharing challenges that prevent people experiencing homelessness from accessing Enhanced Care Management (ECM) and housing-related Community Supports (CS). The CoP provides technical assistance to CoCs and their local MCPs as they develop practical and scalable solutions to achieve data matching and data sharing,  prioritizing simple, low-cost, and secure approaches that respect privacy, minimize administrative burden, and build trust between partners.
