Aim: To determine the outcome and factors influencing outcome among a cohort of drug users commencing detoxification from opiate use.
Methods: National cohort study of randomly selected opiate users commencing methadone detoxification treatment in 1999, 2001 and 2003 (n = 327).
Results: One quarter 62 (25.6%) of opiate users had a successful detoxification within the 3-month study criteria. Receiving some inpatient treatment as part of detoxification programme resulted in completion by 56.3% drug users compared to outpatient only treatment (21%). The factors independently influencing detoxification are as follows: having some inpatient treatment AOR 5.9 (2.63-13.64) and never having injected AOR 2.25 (1.20-4.25). An additional 31 (9%) opiate users had a detoxification between 3 months and 1 year and 27 (8%) moved into methadone maintenance.
Conclusions: This study finds that having some inpatient treatment increases the likelihood of a detoxification within 3 months. Offering a detoxification early in a drug using career pre-injecting drug use should be considered for suitable and motivated patients.
