The Frequent User Services Enhancement (FUSE) initiative is a supportive housing program developed by CSH with support from various government agencies that provided housing and support services to individuals who were frequently cycling in and out of jails, homeless shelters, and hospital emergency rooms in 2008. A two-year follow up evaluation by Columbia University Mailman School of Public Policy found that FUSE participants spent significantly fewer days in jails and shelters and engaged in less cycling between public systems. These service use reductions resulted in significant cost savings to the government and tax payers.
