A substance abuse consultation service. Enhancing the care of hospitalized substance abusers and providing training in addiction psychiatry.

The authors review the literature on the high prevalence but underrecognition of substance abuse among hospitalized patients and the general unavailability of hospital-based substance abuse consultation services. They describe the development, clinical operations, staffing, and teaching activities of a large substance abuse consultation service in one urban academic medical center and detail the service's growth and changing utilization patterns over an 8-year period, reporting the clinical characteristics of 1,819 patients seen over a 1-year period. Differences in patient demographics, patterns of substance use, and diagnoses were highly significant from one referring service to another. The authors discuss the implications of such a service for patient care and teaching.
