Abstract
The aim of this analysis was to specify factors that related to the differences in the states of drug management guidance jobs among hospitals using the administrative data of multiple institutions. We targeted 94 hospitals throughout Japan and used the Diagnosis Procedure Combination (DPC) data and results of a questionnaire survey. In this analysis, the state of implementation of drug management guidance jobs was expressed as an index based on the state of estimation of the fees for drug management guidance, which was converted to a value for each patient and each pharmacist, and used as the objective variable. Other jobs such as handling of sterile drugs or management of fee for specific therapeutic drug monitoring, years of experience, states of introduction of IT systems, and bed occupation rate, etc., were used as the explanatory variables, and multiple linear regression analysis was performed. The results revealed that there was a large dispersion among hospitals in the states of implementation of drug management guidance jobs and this dispersion was related to the number of hospitalized patients per pharmacist, number of outpatient medicines dispensing, and other jobs related to hospitalization. It is considered above findings will be useful when optimizing resource distribution and job designing of pharmacists, however as the coefficient of determination determined from the multiple linear regression analysis was about 0.25, the results also suggested dispersion in the performance of the pharmacy departments.
