Abstract
BACKGROUND: Within the US Department of Veterans Affairs (VA), eligible veterans can receive covered health care through the community care network. Many prescriptions for specialty medications made by community care prescribers are filled by outpatient VA pharmacies. Trained hematology/oncology clinical pharmacy practitioners (CPPs) review specialty medication prescriptions from community-based prescribers. This study's primary objective was to evaluate clinical interventions initiated by hematology/oncology CPPs at the Veterans Affairs North Texas Health Care System (VANTHCS) during their review of hematology/oncology specialty prescriptions from community care prescribers. METHODS: A retrospective chart review of VANTHCS patients enrolled in the community care program with a specialty hematology/oncology prescription received and reviewed by a VA clinical hematology/oncology CPP was conducted for records from January 1, 2015, to June 30, 2023. The primary outcome was the number and types of clinical interventions. Secondary outcomes include the number of interventions accepted and/or denied by the prescriber and the financial implications of these interventions. RESULTS: Two hundred twenty-one specialty hematology/oncology prescriptions met the study inclusion criteria. VANTHCS hematology/oncology CPPs completed clinical interventions for 82 prescriptions (37%). Among those prescriptions, CPPs documented 97 clinical interventions. The most commonly documented interventions included managing/preventing a drug interaction (26%) and dose adjustment requests (25%). CONCLUSIONS: Hematology/oncology CPPs at VANTHCS are essential in reviewing anticancer medication prescriptions from community-based practitioners ; CPPs completed clinical interventions for more than one-third of the prescriptions and prescribers approved most of these interventions.
