Randomized controlled trial of harm reduction treatment for alcohol (HaRT-A) for people experiencing homelessness and alcohol use disorder.

BACKGROUND: People experiencing homelessness are disproportionately affected by alcohol use disorder (AUD). Abstinence-based treatment, however, does not optimally engage or treat this population. Thus, harm reduction treatment for alcohol (HaRT-A) was developed together with people with lived experience of homelessness and AUD and community-based agencies that serve them. HaRT-A is a compassionate and pragmatic approach that aims to help people reduce alcohol-related harm and improve quality of life (QoL) without requiring abstinence or use reduction. A three-month, two-arm randomized controlled trial was conducted to test the initial efficacy of HaRT-A compared to a services-as-usual control condition. METHODS: People experiencing homelessness and AUD (N = 168; 24% women) were recruited in community-based clinical and social services settings. Self-reported alcohol use, alcohol-related harm, motivation, and QoL as well as urinary ethyl glucuronide were assessed over a 3-month follow-up. Participants were randomized to receive HaRT-A or services as usual. Over four sessions, HaRT-A interventionists delivered three components: a) collaborative tracking of participant-preferred alcohol metrics, b) elicitation of harm-reduction and QoL goals, and c) discussion of safer-drinking strategies. RESULTS: Compared to control participants, HaRT-A participants reported significantly greater increases in confidence to engage in harm reduction and decreases in peak alcohol use, alcohol-related harm, AUD symptoms, and positive urinary ethyl glucuronide tests (ps < .05). Findings were inconclusive regarding group differences on QoL (ps > .12). CONCLUSION: A low-barrier, low-intensity, patient-driven, harm-reduction approach has at least short-term efficacy in improving AUD outcomes in this population. Future studies are needed to establish its longer-term efficacy.

Suicidality Among Chronically Homeless People with Alcohol Problems Attenuates Following Exposure to Housing First.

This study is the first to document suicidality among chronically homeless people with alcohol problems (N = 134) and examine its trajectory following exposure to immediate, permanent, low-barrier housing (i.e., Housing First). Suicidal ideation, intent, plans, and prior attempts were assessed at baseline and during a 2-year follow-up. Baseline suicidal ideation was over four times higher than in the general population. Two-year, within-subjects, longitudinal analyses indicated severity of suicidal ideation decreased by 43% from baseline to follow-up. Significant decreases were also found for intent and clinical significance of ideation. No participants died by suicide during the 2-year follow-up.
