Abstract
Time series of the number of outpatients which may influence the number of outpatient prescriptions as an index to the amount of dispensing service at hospital pharmacy was analyzed on the basis of the 62-month survey. The influence was studied statistically. The influence rate (in terms of a square number of correlation coefficient) of the number of outpatients was 14.6% which was not satisfactory as a time series function. The rate of the number of prescriptions to the number of outpatients averaged 54.1%. The monthly variation of the rate was not so large. The influence rate of the number of outpatients to the number of outpatient prescriptions was as high as 62.1%, indicating considerable effect of the number of patients on the amount of dispensing service.
