Early Check-In Protocol: Identifying Medication Issues in Patients with Cancer at Health System Specialty Pharmacy.

Introduction: Several studies have illustrated value in early patient contact following oral anticancer medication (OAM) initiation, particularly within the first 14 days of therapy, as adverse effects may lead to early discontinuation or poor adherence. Health-system specialty pharmacies (HSSPs) are optimally positioned to adopt this best practice through formalized protocols designed to identify and mitigate medication-related issues.

Objective: To outline an HSSP-led early check-in protocol for patients taking OAMs and to describe the subsequent interventions conducted by the HSSP team and their acceptance rate.

Results: HSSPs enacted a protocol in January 2021 requiring oncology pharmacists - to contact patients within 14 days of OAM initiation, aiming to optimize adverse effect management, offer supportive care, address adherence, and provide education. To evaluate the impact of the early check-in protocol, we conducted a retrospective, multicenter, observational study across CPS's health system clients from January 2022 to November 2023. HSSP pharmacists created 1698 interventions for 1184 patients from the early check-in. The cancer types most frequently associated with an intervention were breast (n = 431, 25.4%), gastrointestinal (n = 245, 14.4%), and prostate (n = 206, 12.1%). The most frequent intervention categories were adverse drug reactions (ADRs) (n = 1,548, 91.2%) and adherence (n = 55, 3.2%). Overall, 95.5% of pharmacist recommendations were accepted by patients and/or providers.

Conclusion: Implementing an early check-in protocol allows HSSP pharmacists to mitigate barriers to OAM adherence. This study emphasizes the importance of early check-in and illustrates the scope of the oncology pharmacist's role by evaluating critically meaningful interventions and quantifying pharmacist recommendations and acceptance rate.
