This paper evaluates a model of community mental health service (CMHS) in Al Ain in the United Arab Emirates. The hospital records were reviewed and the total number of patient admissions and duration of in-patient care before and after enrolment in the CMHS were documented. Patient satisfaction with the CMHS was assessed using a questionnaire. The total number of admissions and the number of days that the patient spent in hospital per year were significantly reduced by the CMHS. Patients had high satisfaction rates with the information and advice they received, with their relationships with CMHS workers, with their access to mental health services and with their drug treatment.
