[Research on the Ratio of Anti-Cancer Drug Purchase Costs at Municipal Hospitals in the Aichi Prefecture].

We performed a study on the ratio of anti-cancer drug purchase costs at municipal hospitals in Aichi using meeting materials from the 2020 Aichi Prefectural Public Hospital Pharmacy Directors' Association. The ratio of anti-cancer drug purchase costs to all drug purchase costs at 17 hospitals was 41.5%(average)and 37.1%(median). In addition, we confirmed a positive correlation between all drug purchase costs and the ratio of anti-cancer drug purchase costs for each hospital(r= 0.537, 95%CI: 0.076-0.809, p=0.026). Furthermore, we conducted a univariate analysis on the background of hospitals where the ratio of anti-cancer drug purchase costs is ≥40%. As a result, we confirmed a significant difference(p<0.05)in the cases where there are more than 500 beds, with the approval of designated cancer hospitals, and with the department of hematology. This study clarified that hospitals with active anti-cancer drug treatment tended to increase drug purchase costs.
