Factors associated with pretreatment and treatment dropouts among clients admitted to medical withdrawal management.

The aims of this study were to identify factors associated with pretreatment and treatment dropouts among individuals accessing an inpatient medical withdrawal management program (Vancouver Detox). Two thousand five hundred sixty-six unique clients, who were referred to Vancouver Detox over two-year period, were assessed. Demographic and drug related variables were analyzed as possible risk factors, and two multivariate logistic regression analyses were conducted. We found that being male, being aboriginal, having no children, no fixed address, alcohol as a preferred substance, and being on methadone maintenance treatment at referral were significantly associated with high pretreatment dropout. Significant risk factors for treatment dropout were: being younger, having HCV infection, having a preferred substance other than alcohol, having opiates as a preferred substance, and being discharged on welfare check issue periods or weekends. These findings may help clinicians and decision-makers to initiate corresponding preventive measures to decrease unnecessary attritions and improve utilization of treatment resources.
