A clinic is described which was designed to carry out functional evaluation of patients with chronic medical and psychiatric disabilities and to plan for their vocational rehabilitation. The results obtained in 100 patients evaluated in the clinic during the past 7 years are presented and discussed. Thirty-five of these patients were successfully rehabilitated. Success in rehabilitation varied inversely with the severity of the disability, regardless of specific diagnosis. Statistically significant adverse factors included increasing age, education limited to 8th grade or less, a non-supportive family environment, unemployment, and dependence upon public welfare assistance. Therefore, assessment of all these factors appears to be essential for effective and efficient rehabilitation planning. Adequate follow-up is necessary to maintain the improvements that have been achieved. Perhaps locating such a clinical in a neighborhood setting would improve the quality of referrals and facilitate follow-up care. The team approach to comprehensive evaluation is readily adaptable for use in out-patient clinics. This approach would permit 1 responsible physician to be fully and currently informed in regard to all aspects of a given patient''s problems, and thus to improve greatly the quality and effectiveness of medical care.
