Many communities across the country recognize they have “frequent users” of public crisis systems. Usually homeless, these individuals cycle through hospital emergency departments, local jails, and more. CSH developed the Frequent Users Systems Engagement (FUSE) initiative to stop this cycle with a simple solution: Supportive housing, which is affordable housing with wraparound support services to stabilize individuals in the community. FUSE communities use data from across public systems to identify those frequently using multiple systems, and then create housing that serves as a platform for improving lives and reducing system use. This saves or offsets costs to the homeless, health and corrections systems. As FUSE initiatives have spread to more than 35 communities across the country, data sharing across housing and health care continues to be a challenge. It is critical to find ways to overcome these barriers because demonstrating the effect supportive housing has on reducing crisis-care costs, and shifting to more appropriate, and preventive use of health care, can help to bring more resources to bear to scale up FUSE initiatives and, ultimately, to transform public systems. This session will feature an innovative community using WellSky products. Boise, ID is finding improved ways of integrating homeless and housing data with health care and other systems so they may both identify people for interventions, and track outcomes for those in housing to demonstrate impact. Session participants will walk away knowing the value case for integrating health and housing data, and the impact that housing can have on health care utilization.
