Hypothesis: Patients who are addicted to opioids or alcohol will have reduced substance use, health care utilization if they have immediate and convenient access to pharmacotherapy and addiction counselling. Summary: This randomized trial will compare two different interventions for 124 alcohol and opioid-addicted patients admitted to either Women's Own Detox (WOD) at the University Health Network or the Withdrawal Management Service (WMS) at Saint Michael's Hospital (SMH. The Delayed Intervention group will receive a card with contact information for the St. Michael's Hospital and Women's College Hospital addiction medicine services. The Rapid Intervention group will be seen by an addiction physician from one of these services, within a day or two of their admission to the WOD or the SMH WMS. The addiction physician will prescribe buprenorphine or anti-alcohol medications, and the physician, nurse and/or therapist will provide ongoing counseling, follow-up and shared care with the family physician. Outcomes (measured at 6 and 12 months) include treatment retention, health care utilization and cost, medications prescribed, and alcohol and opioid use.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Opioid dependentExperimental Treatment2 Interventions
Subjects with a possible opioid use disorder, as determined by positive responses on the eligibility form: has used opioids within the past 30 days, opioid use has been a problem, and at least one harmful consequence of opioid use has been present (eg. withdrawal symptoms, or problems with family, friends, work, money etc.).
Group II: Alcohol dependentExperimental Treatment2 Interventions
Patients who indicate they have a problem with alcohol will be asked to complete the AUDIT, a validated, 10-item instrument that measures the severity of an alcohol problem. The AUDIT enquires about core features of alcohol dependence, such as failure to fulfill obligations. A score of 8 or more indicates possible alcohol dependence.
