Fifty facilities qualifying as outpatient psychiatric clinics were studied to determine how admission diagnosis affected the course of the patient''s treatment. Over 5000 admissions were studied. All were residents of Maryland and were under 20 years of age. Over half of these patients received their final interview within a month of completion of studies, only 5% of the group were still under care at the end of eighteen months. Children with brain syndromes or mental deficiency have the shortest period of clinic service. Patients with psychogenic disorders tend to require longer periods of treatment. Children with convulsive disorders tend to require longer courses of treatment than those without convulsions. Mental defectives are retained the shortest period of time. At the end of three months, the percent of patients remaining in the clinic are 24% for the convulsive patients, 12% for those with other brain syndromes and 3% for the mental defective group. In the psychogenic groups, children with psychoneurosis have the longest stay , transient situational personality changes rank next, psychotic disorders, third, and personality disorders, fourth. This varies considerably from clinic to clinic, for sex, and race.
