An Analysis of the Inclusion of Medications Considered Potentially Inappropriate in Older Adults in Chemotherapy Templates for Hematologic Malignancies: One Recommendation for All?

Background There remains a paucity of data regarding the use of potentially inappropriate medications (PIMs) in the supportive management of older adults undergoing chemotherapy. Raising awareness among healthcare providers regarding the frequency of their use and potential toxicities may help to minimize the risks to patients. Objective The aim of this study was to evaluate the frequency of six specific classes of medications considered PIMs by the American Geriatrics Society Beers Criteria that are commonly included in the National Comprehensive Cancer Network (NCCN) chemotherapy order templates for hematologic malignancies. The six PIMs evaluated are first-generation antihistamines, benzodi-azepines, corticosteroids, H-2-receptor antagonists, meto-clopramide, and antipsychotics. Methods A total of 311 unique chemotherapy order templates published online by the NCCN for the treatment of hematologic malignancies were reviewed to determine the frequency that these six specific PIMs were recommended for supportive care. Results Approximately 45% of the NCCN chemotherapy templates for hematologic malignancies specifically recommended the use of at least one of the six PIMs examined. The remainder of the templates evaluated referred exclusively to the NCCN Guidelines (R) on Oncology for Antiemesis, which also included the use of at least one of the six PIMs evaluated. Conclusions These findings demonstrate that PIMs are frequently used as supportive therapy in the treatment of hematologic malignancies. Increasing healthcare provider awareness of their potential side effects may minimize the risks associated with their use in older adults with hematologic malignancies undergoing chemotherapy.
