Evaluating the Impact of a Clinical Pharmacist in Patients Receiving New Chemotherapy for Breast Cancer: Analysis of a Pilot Study

Purpose: Breast cancer treatment may include chemotherapy, which is associated with significant toxicities. At the Sidney Kimmel Cancer Center at Jefferson Health, a pilot program was developed to add an oncology clinical pharmacist to the breast cancer clinic. The purpose of this study is to identify the impact of the clinical pharmacist in supportive care management, add to existing literature discussing the impact of the clinical pharmacist in ambulatory oncology settings, and justify future, permanent ambulatory oncology pharmacist positions within the institution. Methods: This single-center retrospective chart review assesses interventions made by the clinical pharmacist in patients with any stage of breast cancer who presented to the breast clinic for new chemotherapy treatment between September 1, 2020, and February 28, 2021. The primary outcome was to describe clinical pharmacist interventions at the first follow-up encounter after chemotherapy initiation. Secondary outcomes included classifying and quantifying total interventions and comparing intervention details between total and included patients within the 6-month timeframe. Results: Of 44 included patients, 29 had a follow-up encounter. The clinical pharmacist directly managed 33% of the 58 patient-reported adverse drug effects. In 6 months, the clinical pharmacist made 1,068 interventions spanning 189.6 documented hours. The most common interventions were coordination of care, education, and supportive care pharmacotherapy interventions. Conclusion: This study identified the pharmacist’s role in supportive care management and reports the successful integration of a clinical pharmacist into a breast cancer clinic. Future directions include conducting prospective studies to further explore the impact of the clinical pharmacist on treatment outcomes.
