简要总结
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.

结局指标
主要结局
Treatment retention
时间窗: 12 months
The number of subjects in each group that attend the addiction service, and the mean number of visits per subject.
Healthcare utilization and cost
时间窗: 36 months
For each subject the ICES (Institute for Clinical Evaluative Sciences) linked administrative databases will be used to track, from 24 months before to 12 months after the initial visit: a) the number of hospitalizations and number of hospital days (Canadian Institute for Health Information (CIHI) Discharge Abstract Database), b) Emergency Department (ED) visits (CIHI National Ambulatory Care Reporting System), c) primary care visits and outpatient laboratory services (Ontario Health Information Plan Database). During the monthly telephone calls and at the 6 and 12 month visits, the Research Assistant (RA) will ask subjects about recent ED visits, hospitalizations and outpatient medical visits
Prescriptions
时间窗: 36 months
For patients eligible for pharmacotherapy, ICES will be used to evaluate pre-post (prescribing from 24 months before study entry to 12 months after) changes in opioid and benzodiazepine prescribing, and prescribing of buprenorphine, methadone, and anti-alcohol drugs.
Substance use
时间窗: 12 months
The research assistant will conduct interviews at baseline, 6, and 12 months during which subjects will be asked about changes in substance use.
