We investigated the actual status of antipsychotics maintenance therapy(AMT) for schizophrenic patients through a mail survey sent to psychiatrists practicing in Seoul and Kyeongi province who had no less than two years of psychiatric expertise and who were below fifty years of age. Out of 453 questionnaires sent, 215 completed questionaires were returned(response rate 47%). The majority of respondents considered pharmacotherapy as the most important longterm treatment strategy for schizophrenia. Haloperidol was selected by the majority as their first choice neuroleptics. The proposed mean daily maintenance dosage was 383±229(75-1250)mg in chlorpromazine equivalent. The mean duration of AMT was 1.8±1.0(0.25-7.5)years after the first episode and 3.6±1.8(0.5-10) years after multiepisodes. Psychotherapy was regarded as more important by the resident psychiatrists group than by the certified psychiatrists group. There were preferential differences for a particular treatment strategy, dosage and duration of AMT among the different clinics. A great number of respondents(93%) regarded long-term continuous maintenance as their major AMT policy. Only a few respondents(4.3%) were satisfied with the established guidelines for AMT in treatment of schizophrenia. The results show considerable variations in psychiatrists opinions on AMT which was influenced by grades of expertise of the clinician and the working environment of the clinic or the hospital. To decrease these variabilities and make clinically useful guidelines, it will be necessary to do further pharmacoepidemiological studies as well as other types of related clincal research.
