Managing medications for patients with cancer and chronic conditions: It's time for collaboration between primary care and oncology pharmacists.

Objective: To provide a rationale for a collaborative care model involving oncology and primary care pharmacists to improve the coordination of care of medications for cancer patients with multiple chronic conditions.

Data sources: A review of selected literature and the authors' own research was used. Studies illustrating the gaps in care for medications and pharmacists' roles in oncology and primary care settings from PubMed were reviewed.

Data summary: There has been a substantial increase in the development and utilization of oral anticancer agents (OAAs). Although OAAs offer convenience and flexibility, they also introduce challenges related to medication adherence, monitoring, and managing side effects. Up to 17.5% of patients experience moderate to severe symptoms from OAAs and about 30% report less than excellent medication adherence. Further, studies showed that 30% to 53% of adult cancer patients have at least one chronic condition that complicates their treatment plan due to the need for medications, increasing the risk of drug interactions, side effects, and non-adherence. The Primary Care Oncology Model (PCOM) incorporates both primary care and oncology pharmacists with comprehensive medication review and patient-reported outcome measure, respectively, to enhance medication appropriateness and effectiveness, and improve overall patient experience.

Conclusion: Implementing PCOM may improve the medication management of patients taking OAAs for active cancer treatment and chronic medications for their multiple chronic conditions. This collaborative approach can transform patient care by leveraging the expertise of both primary care and oncology pharmacists.
