Evaluation of the role and usefulness of a pharmacist outpatient service for patients undergoing monotherapy with oral anti-cancer agents.

Introduction When rapid feedback to physicians must be provided, e.g. monitoring therapy with the oral anticoagulant warfarin or providing therapeutic support for patients undergoing cancer chemotherapy, the involvement of pharmacists is required for outpatients. We launched a pharmacist outpatient service for patients with cancer taking oral anti-cancer agents. We evaluated the role and usefulness of the pharmacist outpatient service for these patients undergoing oral monotherapy with anti-cancer agents. Methods Data regarding prescription recommendations were collected from the drug management guidance records of 154 patients who consulted the pharmacist outpatient service between July 2013 and September 2015. In addition, the rates of prescription recommendation adherence were calculated. Between April and August 2015, a self-reported questionnaire was administered to 47 patients undergoing therapy with oral anti-cancer agents who were visiting the pharmacist outpatient service at the Ogaki Municipal Hospital (Ogaki, Japan). Results Prescription recommendations were given to 235 cases. The total rate of adherence to the prescription recommendations was 94.9% (223/235 cases). The majority of prescription recommendations regarding supportive care were those for moisturizing agents (20.9%), analgesics (20.9%), steroid ointments (12.7%), and antihypertensive agents (10.8%). When continued guidance was provided, significant changes were observed for survey items 3 (knowing the side effects of the medication), 8 (worrying about side effects), and 12 (interest in prescribed medicine) ( p = 0.0049, p < 0.0001, and p = 0.0164, respectively). Conclusion Our study showed that continued pharmaceutical intervention resulted in a deeper understanding of the medications' side effects, and it reduced anxiety levels in patients undergoing monotherapy with oral anti-cancer agents.
