Understanding oral chemotherapy prescribing patterns at the end of life at a comprehensive cancer center: Analysis of a Massachusetts payer claims database

Abstract

Purpose: Receipt of chemotherapy in the last 14 days of life is a measure of potential overuse of care. Specific measures defining appropriate end-of-life use of oral agents have not yet been described, and little is known about prescribing patterns. Methods: We conducted an exploratory analysis of 371 patients at Dana-Farber Cancer Institute who were covered by the Blue Cross Blue Shield of Massachusetts pharmacy benefit and died during 2012 to 2013. We analyzed processed claims as a surrogate for chemotherapy administration. We compared oral with parenteral chemotherapy claims in the last 6 months of life. Results: In the last 6 months of life, 294 patients (79%) had chemotherapy claims, including 81 (22%) prescribed an oral agent; 20 patients had claims for oral chemotherapy in the last 30 days of life. For eight patients (40%), this was the initial start of that oral agent. In the last 14 days of life, only 23 patients had chemotherapy claims, including six patients prescribed an oral agent. Conclusion: The collection of oral chemotherapy use data through insurance claims was feasible. Processed claims for chemotherapy, including oral, sharply declined during the last 30 days of life, consistent with a shift to palliative management. These results highlight the need for a more comprehensive analysis of oral chemotherapy prescribing patterns and development of specific measures to define the appropriate use of oral chemotherapy at the end of life.
