Background: Poor adherence to oral anticancer medications (OAMs) is a well-recognized problem in oncology, however adherence to OAMs among veterans is largely unknown. Medication cost is often mitigated, however higher rates of comorbidities within the veteran population may contribute to impaired adherence. Additionally veterans living outside local catchments may be at increased risk for non-adherence or inadequate follow up due to geographic burden.

Cancer rates nationwide are projected to increase over the next 10-20 years. The Veterans Health Administration is the largest integrated health care system in the US, and characterizing OAM adherence and any potential barriers is valuable in improving veterans’ care.

Project Description: The purpose of this study is to investigate and characterize adherence to OAMs and recommend safety monitoring studies among US veterans enrolled at the VAPORHCS, as part of a fellowship quality improvement program initiative. This is a retrospective chart review of all veterans followed within the VAPORHCS hematology/oncology fellows’ clinic, who were taking OAMs from March 1, 2018 to March 1, 2019. Fellows reviewed their own panels, with an internal medicine faculty member performing an independent review on a portion of the charts. Information collected includes adherence to medications as well as recommended monitoring, as determined by provider notes, pharmacy records, and lab and imaging records. Additional information collected includes demographics, co-morbidities, polypharmacy, and service connection.

Results: Primary co-objectives of this project will be determining adherence to both medications and recommended routine monitoring studies (ie labs, imaging, and follow-up appointments). Secondary objectives will be characterizing adherence in relation to other patient factors, such as age, geographic location, primary malignancy, co-morbidities, polypharmacy, and service connection. This project was initiated in fall of 2018. The data has currently been all collected and is undergoing review and analysis. Full results should be available by end of July 2019.

Data Analysis: Initial data processing and univariate analysis is currently ongoing. We currently have plans to pursue multivariate analysis of the results through the Oregon Health and Science University Biostatics Shared Resource (BSR) Department.
