Assertive Community Treatment For People With Alcohol Dependence: A Pilot Randomized Controlled Trial

Area of Science:

• Addiction Medicine
• Psychiatry
• Public Health

Background:

• Alcohol dependence is a significant public health issue requiring effective treatment interventions.
• Previous treatments for alcohol dependence have shown limited success in some patient populations.
• Assertive Community Treatment (ACT) is an intensive outreach model typically used for severe mental illness.

Purpose of the Study:

• To evaluate the feasibility of implementing Assertive Community Treatment (ACT) in adults with alcohol dependence.
• To assess the potential efficacy of ACT compared to treatment as usual (TAU) in this population.
• To examine the impact of ACT on drinking patterns, engagement, and healthcare utilization.

Main Methods:

• A pilot randomized controlled trial (RCT) involving 94 adults with alcohol dependence and prior treatment failures.
• Participants were randomized to 12 months of ACT plus TAU or TAU alone.
• Primary outcomes included mean drinks per drinking day and percent days abstinent at 12 months, with secondary outcomes on engagement and healthcare use.

Main Results:

• ACT demonstrated feasibility and improved participant engagement, with more home/community-based contacts.
• The ACT group showed a higher percentage of days abstinent at 6 months but reported more drinking-related problems and lower quality of life at 12 months.
• The ACT group experienced less unplanned healthcare utilization compared to the TAU group.

Conclusions:

• Assertive Community Treatment (ACT) is a feasible intervention for adults with alcohol dependence within specialist community services.
• Further research is warranted to optimize ACT for alcohol dependence, balancing engagement with overall well-being.
• ACT may offer benefits in reducing healthcare resource use for individuals with severe alcohol dependence.
