Correlativity of the number of prescriptions for inpatients with that of groups of drugs in prescriptions, and of drugs prescribed, as well as the characteristics of the medication order patterns, was studied. Great correlativity was observed in the number of prescriptions with the number of groups of drugs and that of drugs prescribed. Since the regression lines of these items showed great statistical significance, it must be possible to estimate the number of groups of drugs, drugs prescribed, etc. from the number of prescriptions by means of the formula of the regression lines. In order to know the proper amount of dispensing service, it is necessary to select the investigation items depending on the contents of prescriptions.
