[Survey of Pharmaceutical Interventions in Outpatient Cancer Chemotherapy].

In recent years, cancer chemotherapy has been administered in an outpatient setting; therefore, patient self-management of adverse events is an important issue. Pharmaceutical interventions were performed by pharmacists at the following 3 time points: before the physician consultation, after the physician consultation, and during multidisciplinary conferences at the Ibaraki Prefectural Central Hospital Cancer Chemotherapy Center. In this study, prescription proposals and their effectiveness for adverse events, were investigated. Of the 338 cases in which pharmaceutical interventions were performed, 280 were accepted by physicians, and the acceptance rates were 77% in conference, 89% before physician consultations, and 85% after physician consultations. Pharmaceutical interventions for the management of nausea and vomiting were most frequently accepted (96 cases), with improvement observed in 58 cases (60%). Improvement rates for hypertension and skin disorders were 76% and 56%, respectively, and improvement rates for peripheral neuropathy and dysgeusia were 33% and 22%, respectively. Of all interventions made by pharmacists, 68% were for the 1st 5 courses, with proposals continuing beyond the 6th course, suggesting that there is demand for long-term intervention. Pharmacists collecting patient information and implementing pharmaceutical interventions may contribute to the management of adverse events. As the degree of improvement varies according to the type of adverse event, it will be necessary to establish optimal pharmaceutical interventions in the future.
