Improving entry to methadone maintenance among out-of-treatment injection drug users

Abstract

This study of 577 out-of-treatment drug injectors was designed to assess predictors of methadone maintenance treatment entry, including offering free treatment coupons. Using targeted sampling methods, participants were recruited through street outreach; randomly, they were either assigned a coupon for 90 days of free treatment or required to pay for their treatment. Regardless of assignment, all subjects who desired treatment were provided transportation, rapid intake, and a waiver of the treatment entry fee. Overall, 33% entered treatment, including 66% of those who received a free coupon. Other factors associated with treatment entry included desire for treatment, heroin use, prior treatment experience, associating with fewer drug-using friends, and injecting with a previously used unsterile needle/syringe. Injecting cocaine and smoking crack reduced the probability of treatment entry. Findings lend support to street outreach efforts designed to increase rates of treatment entry among chronic out-of-treatment drug injectors. Additional treatment options are required for those abusing cocaine.
