Implementation and evaluation of a shared care model between oncologists and pharmacists for breast cancer patients at a Canadian regional ambulatory cancer centre.

Abstract

Background: The introduction of CDK 4/6 inhibitors for breast cancer patients has contributed to increased ambulatory patient visits for oncologists. The Medication Assessment by Pharmacist program aims to evaluate the impact of oncology pharmacists performing medication assessment follow-up visits.

Methods: Breast cancer patients on a CDK 4/6 inhibitor deemed suitable by their oncologist for pharmacist assessment could be booked for a pharmacist medication assessment appointment at alternate treatment cycles.

Results: Between February 2019 to November 2021, 29 of 128 patients (22.7%) were selected for 46 total Medication Assessment by Pharmacist visits resulting in 920 min of clinic time savings for physicians. There were similar rates of adhering to provincial protocols for scheduling visits (99% vs. 96%, p  =  0.12) and monitoring investigations (98% vs. 98%, p  =  0.96) between those enrolled in Medication Assessment by Pharmacist or not. Surveys completed by medical oncologists and pharmacists demonstrated that nine of nine oncologists felt Medication Assessment by Pharmacist reduced workload and wanted Medication Assessment by Pharmacist expanded to additional oncology drugs. Pharmacist-completed surveys revealed that nine of nine pharmacists felt Medication Assessment by Pharmacist increased job satisfaction, and allowed further application of clinical skills. All agreed that patients were receptive to meeting with pharmacists. According to survey results, 33% of oncologists versus 100% of pharmacists routinely asked about medication adherence, new medications or supplements.

Conclusion: Integrating pharmacists into a shared care model reduces ambulatory patient visits for oncologists without deviating from provincial protocol guidelines for monitoring and visits for patients on CDK 4/6 inhibitors. Leveraging the medication expertise of pharmacists also increases the frequency of addressing medication adherence and concurrent therapies. Medication Assessment by Pharmacist may be an effective strategy in alleviating projected shortages of oncology providers.
