Brief intervention in general hospital for problematic prescription drug use: 12-Month outcome

In contrast to the short-term effects after 3 months, no long-term effects of brief MI sessions on PD use were found. More intensive interventions, booster-sessions or regular aftercare might help in stabilizing intervention effects on PD use among hospital patients. However, studies using larger samples are needed to allow more powerful and specific analyses. Different samples should be examined. Problems concerning the recruitment of study participants in PD research were discussed and should be considered in further studies.
