Impact of pharmacy collaborating services in an outpatient clinic on improving adverse drug reactions in outpatient cancer chemotherapy.

Background: Collaboration between pharmacists, doctors, and nurses in outpatient treatment is beneficial; however, such services are limited in Japan due to the lack of a healthcare reimbursement fee for outpatient pharmacy services at outpatient clinic.

Objective: We evaluated the impact of a service in which clinical pharmacists collaborated with an oncologist at an outpatient clinic in the treatment of adverse drug reactions in outpatient cancer chemotherapy.

Methods: We performed a retrospective cohort study using patients' medical records and treatment diaries.
