Impact of pharmacist intervention on anticoagulation management and risk for potential COVID-19 exposure during the COVID-19 pandemic.

Introduction: Patients taking warfarin require frequent international normalized ratio (INR) monitoring in healthcare settings, putting them at increased risk of Coronavirus disease 2019 (COVID-19) exposure during the pandemic. Thus, strategies to limit in-person visits to healthcare facilities were recommended by the Anticoagulation Forum. The objective of this study was to describe the number and types of changes made to anticoagulation therapy as a result of pharmacist intervention during the COVID-19 pandemic.
