A study published in 2010 (1) examined the factors associated with lapse and relapse (2) in a prospective follow-up study of opiate users who had been admitted to an Irish residential detoxification facility between June 1995 and December 1996. Follow-up interviews were conducted by out-reach workers between June 1998 and March 1999.  

Of the 109 participants, 99 (91%) reported a relapse. Within the first week of discharge, 72 (66%) had lapsed and 64 (59%) had relapsed. Only 42 (32%) of those recruited had completed the full six-week programme.
 
The study identified several factors independently associated with early relapse: being aged 20 to 24, not having a partner who used opiates, history of injecting drug use, heroin use of between 1.5 and 3 ‘quarters’ per day, and failure to complete treatment or enter aftercare (Table 1).

This study, based on data collected in the late 1990s, found that lapse and relapse occurred very soon after opiate detoxification: 80% of participants had lapsed within the first month. The study findings are similar to those of international studies based on more recent data. The authors recommend that clients should be provided with improved psychological supports both before and after entering residential opiate detoxification. These include encouraging clients to remain for the full treatment period, improving relapse prevention supports, especially during the first week after discharge, and providing prompt access to aftercare.

2. A lapse was defined as any misuse of an opiate after discharge, and a relapse as a return to a pattern of daily opiate use.
