Relationships Between Patient Characteristics and Unsuccessful Substance Abuse Detoxification

OBJECTIVE: History and laboratory evaluations are common for patients entering substance abuse detoxification programs. We sought to identify if patient history and laboratory characteristics entering a detoxification program were associated with unsuccessful detoxification. DESIGN: Retrospective cohort study of 186 patients of a residential-inpatient short-term medical detoxification facility. Unsuccessful detoxification was defined as leaving for urgent medical referral or against program advice. RESULTS: Patients were predominantly male, middle-aged, minority, unemployed, and poly-substance users. Twenty-four patients (13%) did not complete the detoxification program (4 left for urgent medical referral, 20 left against program advice). Unsuccessful detoxification was associated with nausea and/or vomiting (p = 0.032), Caucasian race (p = 0.002), and opiates as a drug of choice (p = 0.018). Laboratory abnormalities were common but none were associated with unsuccessful detoxification. CONCLUSIONS: For patients admitted to a medically monitored detoxification facility, few patient characteristics were associated with detoxification outcome. Routine admission laboratories without clinical correlation may be unwarranted.
