Models of care in New York State Medicaid substance abuse clinics: range of services and linkages to medical care

Purpose: to explore the range of health care services in substance abuse clinics. Methods: survey of directors of a stratified random sample of 125 substance abuse treatment clinics offering methadone, drug-free therapy, or both, representing 344 clinics participating in the New York State (NYS) Medicaid program. Survey asked about clinic services and referral patterns. We defined five categories of linkage of substance abuse to medical care ranging from unlinked (e.g. referral to distant sites) to highly linked (e.g. on site). To estimate the number of patients served, State data on licensed patient capacity for each clinic were used. Results: This sample represented 344 clinics statewide serving an estimated 60,914 patients. For patients with acute, chronic, or HIV-related medical conditions, weighted analyses showed highly linked care in 54 of the 344 (16%) clinics statewide, serving an estimated 13,741 patients. Unlinked care for all these medical conditions was found for 28% of statewide clinics, serving an estimated 8866 patients. Clinics offering both methadone and drug-free therapy were generally more likely to have medically related services on site. Implications: The extent of medical care services available at substance abuse clinics varies widely. Over one-quarter of clinics offered only loosely connected medical and substance abuse care.
