Pilot study evaluating feasibility and utility of pharmacist-driven oral antineoplastic agent monitoring program

Introduction: Oncologists are increasingly prescribing oral antineoplastic agents which have benefits and challenges impacting patient outcomes. Practice guidelines recommend monitoring symptoms and adherence without outlining any specific tools or methods for monitoring. Pharmacists are successful in monitoring patients on therapy and improving outcomes. We aimed to assess the feasibility and utility of a pharmacist-delivered and medical record-integrated adherence and symptom monitoring program for patients on oral antineoplastic agents. Methods: This single-center, prospective, interventional study designed and implemented an adherence and monitoring program. A pharmacist contacted patients twice between clinic visits for three months. During telephone encounters, patients were verbally screened for medication adherence and assessed for new or changing symptoms using the Edmonton Symptom Assessment System as a signal of possible adverse events. We measured feasibility via patient enrollment, completed proportion of scheduled contacts, and pharmacist time. Utility was assessed through patient adherence, satisfaction surveys, healthcare resource utilization, and pharmacist interventions (i.e., patient education, adherence assistance, and symptom management). Results: Fifty-one patients participated. Ninety-one percent of scheduled patient contacts were completed. Edmonton Symptom Assessment System was administered by pharmacy personnel 102 times. Patient-reported adherence was 100%. Overall satisfaction was 85% and 100%, for patients and physicians, respectively. Fifty-one (98%) pharmacist recommendations were accepted. There were 14 total utilizations of healthcare resources—5.2 per 1000 patient days. Conclusions: This study suggests a pharmacist monitoring program for patients taking oral antineoplastic agents is feasible and provides utility. Further research is needed to evaluate whether this program improves safety, adherence, and outcomes in patients using oral antineoplastic agents.
