A comparison of participant's satisfaction with injectable diacetylmorphine and hydromorphone treatment in a double-blind randomized controlled trial for the treatment of long-term opioid dependence
A total of 202 long-term opioid dependent men and women in Vancouver, Canada were randomly assigned. At 6-months follow-up, participants completed the Client Satisfaction Questionnaire (CSQ) and additional data on sociodemographic, drug use and retention to treatment. The CSQ ranges from 8-32; higher scores indicate higher satisfaction. Bivariate and multivariate analyses (in progress) were used to determine predictors of treatment satisfaction.
At the 6-months follow-up, 194 (96.0%) participants completed the CSQ. Participants in both treatment groups were highly satisfied with treatment (overall mean satisfaction score=28.3; standard deviation=4.1) with no significant differences by treatment group (p=0.40). Preliminary results indicate that satisfaction with treatment was not associated with participant’s age (p=0.577), gender (p=0.404) or ethnicity (p=0.83). However, participants retained to treatment (p<0.001) and with lower use of illicit heroin (p<0.001) had significantly higher mean satisfaction scores.
Preliminary findings indicate that participants randomized to receive innovative injectable treatments were highly satisfied. Satisfaction was also positively associated with injectable treatment retention and illicit heroin use. The findings further emphasize the value of engaging patients in evaluations of received treatments for improving patient success.
