Private and public ownership in outpatient substance abuse treatment: Do we have a two-tiered system?

As investor-owned organizations increase their presence in the mental healt h care sector, questions emerge regarding the effects of ownership type on service delivery. One important question is whether ownership is related to patient access to care for persons requiring treatment for substance abuse problems. Using data from a 1995 national survey of outpatient substance a buse treatment units, the authors investigate whether there are differences in measures of patient access to care among investor-owned, not-for-profit , and public provider organizations. Results indicate investor-owned units carer to and serve a clientele that differs from that of not-for-profit and public units, suggesting the presence of a two-tiered system of substance abuse treatment.
