High-Frequency Users of Detoxification: Who Are They?

Utilizing a longitudinal database (1996-2002) with all intake information from entries to all licensed drug treatment programs in Massachusetts (N = 27,801), this study examined factors associated with multiple detoxification admissions by injection drug users (IDUs). Four logistic regression models were developed. Although our hypothesis was that the highest frequency treatment users (in the 95th percentile) would be those in the detoxification-only group, this was incorrect: the highest frequency detoxification users were those most likely to use detoxification along with methadone maintenance, outpatient counseling, and/or residential treatment. Health insurance was a key factor. Study implications, limitations, and future research directions are noted.
