PURPOSE: Since the approval of cyclin-dependent kinase 4/6 inhibitors in 2015, this oral cancer (OC) therapy has been combined with oral endocrine therapy as first-line treatment in metastatic hormone receptor-positive breast cancer, adding unique toxicity and complexity to the successful administration of this oral medication. Implementation of OC is challenging because of delays in treatment and nonadherence and is worse among vulnerable patient populations. Pharmacists may mitigate these barriers with facilitation of prior authorizations, communication with pharmacies, toxicity management, adherence counseling, and optimization of dosing schedules and regimens. MATERIALS AND METHODS: We conducted a quality improvement project to decrease the average number of treatment day delays during the first six cycles of OC. Patients were enrolled on the OPTIMAL protocol, a high-touch pharmacy intervention incorporating pharmacists within outpatient oncology clinic visits with the providers. Pharmacists met with patients, identified individual barriers to treatment, and performed counseling including toxicity and adherence assessments. RESULTS: A preintervention assessment identified an average treatment day delay of 7.7 (range, 3.2-15.3) days during the first six cycles of OC. During the intervention period, 53 patients were enrolled on the OPTIMAL protocol and experienced an average treatment day delay of 2.1 (0.6-4) days, P < .0001. Delays were characterized as modifiable and unmodifiable. Pharmacists documented 640 interventions, including medication reconciliations and clinical recommendations. Forty-two patients reported treatment-related toxicities, resulting in 33 therapy and 20 dose modifications. CONCLUSION: Our initiative to incorporate pharmacists in clinic visits at an outpatient breast cancer clinic was associated with decreased treatment day delays during the first six cycles of treatment. Pharmacists performed a multitude of meaningful interventions to facilitate treatment in a particularly vulnerable population and play a valuable role in comanaging patients.
