Objectives：Considerable variations in the contents of clinical practice are the natural consequences of the fact that so many factors can have influences on each clinical decision making processes in the psychiatric treatment, let alone the pharmacotherapy of schizophrenia. To attain the goal of rational treatment, it is needed to examine the actual contents of clinical practices and the degree of variations among diverse hospitals. In addition, it is also needed to look into the unique situations in which each hospital is situated. For this purpose, this study tried to investigate the degree of variations in several aspects of the treatment of schizophrenia with atypical antipsychotics currently practiced in Korea. Methods：This study is based on the data from RODOS (Risperidone Olanzapine Drug Outcome Study) in Korea. This study had been designed as a multi-center naturalistic study, therefore, had many advantages for the survey study of actual clinical practices. The subjects of the study were the in-patients who had been given risperidone or olanzapine for the control of their psychotic symptoms. Clinical data had been gathered by retrospective chart review. The degree and the characteristics of the variations were examined by comparing the patient-characteristic variables and the treatment-related variables among each hospital. Results：The differences in the baseline characteristics of the patients including the duration of illness and the past history of psychiatric treatment were substantial among each hospital, and these differences seemed to explain a great portion of the variations in the contents of treatment. The variations in the dosage of risperidone and olanzapine were not conspicuous among each hospital. However, the variations in other treatment-related variables, including duration of admission, proportion of combined therapy with other antipsychotics, usage of anticholinergics, detection rate of extrapyramidal symptoms, remained statistically significant after adjusting the baseline patient characteristics as covariates. Although no significant correlation among each variable was found, a couple of unique practice patterns common to several hospitals could be observed. Conclusions：Considerable variations in the diverse treatment-related variables were observed in the treatment of schizophrenic patients with risperidone and olanzapine. It seemed that the major portion of these variations could be explained by the characteristic of patient group. However, the possibility remained that the other factors including the socio-cultural environment of the community and the disposition of the clinician themselves were still the major contributing factors to these variations. It is expected that the future clinical practice surveys like this study can help the clinicians to reevaluate their current practices, and can help to accumulate the basic data needed to establish the more rational and customized treatment practices.
