Background: Oncologists are increasingly prescribing oral antineoplastic agents (OAAs), which reduce office visits and avoid infusion-related complications.1 However, many OAAs have challenging administration schedules and significant adverse reactions. The burden of medication administration and monitoring shifts to the patient or caregiver, which can affect adherence, safety, and outcomes.2 Practice guidelines recommend prescribers monitor patients for symptoms and adherence, but do not provide specific monitoring recommendations or survey tools.3,4 Studies support that pharmacists play an integral role in monitoring medication safety and adherence (including access) and improve side-effect management and patient satisfaction.5,6

Objectives: To evaluate the (1) feasibility and (2) physician- and patient-perceived benefit of a pharmacist-delivered adherence and symptom monitoring program for patients taking OAAs.

Methods: Feasibility was evaluated through patient participation in a pilot program. Perceived benefit was evaluated with satisfaction surveys. Over 6 months we enrolled patients at a University of Texas outpatient cancer clinic who received any of the following 6 OAAs: capecitabine, sorafenib, regorafenib, osimertinib, afatinib, or erlotinib. A pharmacist was scheduled to contact patients twice each cycle or month, between clinic visits, for symptom or adherence monitoring over a 3-month follow-up. Pharmacy monitored the symptoms using the Edmonton Symptom Assessment Scale (ESAS-FS) and adherence.6 A pharmacist managed or triaged symptoms (ie, diarrhea, mucositis, rash, nausea, and vomiting) per protocol in collaboration with the physicians. Patient contact was recorded directly in the institution’s electronic health record. Physicians, physician assistants, and patients completed satisfaction surveys.

Results: Of the 51 patients screened for eligibility, 48 (94%) participated in the study. The patients’ median (interquartile) age was 59 years (range, 51-68 years), and the patients were predominantly female (65%) and Hispanic (65%). CareLink, a safety-net program, accounted for 33% of insurance coverage, with 48% of individuals having Medicare or Medicaid. Of 361 expected encounters with patients, 252 (88.5%) were performed. The ESAS-FS was administered by pharmacy 102 times, with the median total score severity decreasing over time. A total of 48 symptom management recommendations were made to patients and to physicians, with an acceptance rate of 98%. Patients and physicians agreed with the majority of the statements (96% and 90%, respectively), indicating that the program was helpful. Although 97% of patients would recommend the program to others, only 45% agreed that it improved communication with their physicians.

Conclusion: The findings of this quality improvement study suggest that a pharmacist monitoring program for patients taking OAAs is feasible and shows perceived benefit by patients and by physicians. Further research is needed to evaluate whether this program improves safety, adherence, and outcomes in patients using OAAs.
