SAMHSA's annual Treatment Episode Data Set (TEDS) provides data on completion rates by race, gender, primary substance of abuse, and type of residential treatment for those with discharge information provided by the States for their specialty substance abuse treatment facilities.
In 2005, clients discharged from short-term residential treatment (30 days or less) were more likely to complete treatment than those discharged from long-term residential treatment (57% vs. 38%).
Among short-term residential treatment discharges, a higher proportion of American Indian/Alaska Natives (63%) and Asian/Pacific Islanders (60%) completed treatment than Whites (57%), Blacks (55%), or Hispanics (52%).
Clients who reported alcohol as their primary drug of abuse were more likely to complete treatment among residential short-term discharges (66%) and long-term discharges (46%) than those with other primary drugs of abuse.
Discharged clients who reported stimulants as their primary drug of abuse were the least likely to complete short-term residential treatment (46%) and were almost as likely (19%) as those reporting opiates (21%) as their primary drug to drop out of short-term residential treatment.
Treatment completion among clients discharged from long-term residential treatment was lowest among those reporting cocaine abuse (33%) or opiate abuse (35%) as their primary drug of abuse.
