Summary: this study seeks to implement wrap around services for veterans suffering from co-occurring mental illness and substance use and who are homeless. it will compare implementation as usual of mission to facilitation implementation of mission.

background: homeless veterans often have multiple health care and psychosocial needs, including assistance with access to housing and health care, as well as support for ongoing treatment engagement. the department of veterans affairs (va) developed specialized homeless patient alignment care teams (hpact) with the goal of offering an integrated, "one-stop program" to address the housing and healthcare needs of homeless veterans. however, while 70% of hpact's veteran enrollees have co-occurring mental health and substance use disorders (cod), hpact does not have a uniform, embedded treatment protocol for this subpopulation. one wraparound intervention designed to address the needs of homeless veterans with cod which is suitable to be integrated into hpact clinic sites is the evidence-based practice called maintaining independence and sobriety through systems integration, outreach, and networking-veterans edition, or mission-vet. despite the promise of mission-vet within hpact clinics, implementation of an evidence based intervention within a busy program like hpact can be difficult. the current study is being undertaken to identify an appropriate implementation strategy for mission-vet within hpact. the study will test the implementation platform called facilitation and compared to implementation as usual (iu). aims: (1) compare the extent to which iu or facilitation strategies achieve fidelity to the mission-vet intervention as delivered by hpact homeless provider staff. (2) compare the effects of facilitation and iu strategies on the national hpact performance measures. (3) compare the effects of iu and facilitation on the permanent housing status. (4) identify and describe key stakeholders' (patients, providers, staff) experiences with, and perspectives on, the barriers to, and facilitators of implementing mission. design: type iii hybrid modified stepped wedge implementation comparing iu to facilitation across 7 hpact teams in 3 sites in the greater los angeles va system. discussion: integrating mission-vet within hpact has the potential to improve the health of thousands of veterans but, it is crucial to implement the intervention appropriately in order for it to succeed. the lessons learned in this protocol could assist with a larger roll-out of mission within hpact.
