Innovative and tailored approaches are needed to reduce barriers to treatment and increase utilization of BUP in this population. This study describes a pilot Mobile Community\u2010based Access Team (M\u2010CAT) that used mobile technology and FaceTime in addition to existing community\u2010based case management programs to provide BUP treatment for veterans with OUD experiencing homelessness who had difficulties engaging in the regular BUP clinic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a retrospective chart review of veterans enrolled in M\u2010CAT or the usual BUP clinic between January 2015 and December 2017 (N\u2009=\u200936).

At the endpoint, 66.7% (n\u2009=\u20098) in M\u2010CAT and 100% (n\u2009=\u200924) in BUP clinic remained on BUP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion and Conclusion<\/jats:title><jats:p>M\u2010CAT is an innovative and tailored pilot project that successfully integrated specific OUD medication treatment into existing case management programs for veterans experiencing homelessness using mobile technology and Facetime.
