PHAR’s Sheila Reddy, PhD, MSc, RPh, Eunice Chang, PhD, Katalin Bognar, PhD, and Marian Tarbox, MPP, in collaboration with Genentech, Inc., identified antiviral treated and untreated patients ≥66 years old with an influenza diagnosis during flu seasons 2016-2018 in a retrospective study of Medicare Fee-For-Service claims from the 100% Research Identifiable Files. Results showed prompt antiviral treatment may be associated with reduced mortality, healthcare resource utilization, and economic burden in elderly Medicare beneficiaries with seasonal influenza. These findings were presented at AMCP Nexus; the poster can be viewed here, and the abstract was published in the October supplement issue of the Journal of Managed Care & Specialty Pharmacy.
