Is managed care closing substance abuse treatment units

: Despite high levels of unmet need for outpatient substance abuse treatment, a significant percentage of outpatient units have closed over the past several years. This study drew on 1999-2000 and 2005 national surveys to determine if managed care was associated with outpatient substance abuse treatment units' likelihood of surviving. Each substance abuse unit director was asked about the presence of any managed care contracts, percentage revenues from managed care, percentage of clients for whom prior authorization was required, and percentage of clients for whom concurrent review was required. A multiple logistic regression revealed that none of these factors was associated with substance abuse treatment unit survival. At this point, neither the presence nor the structure of managed care appears to affect the survival of outpatient substance abuse treatment units. Given the need for these facilities, however, and their vulnerability to closure, continued attention to managed care's potential influence is warranted.
