Does patient self-testing (home INR monitoring) reduce stroke, thromboembolism, major bleeding, and emergency department visits compared to office-based monitoring in warfarin users?
Real-world claims data suggests that patient self-testing for warfarin INR monitoring is safe and associated with fewer adverse clinical events compared to traditional office-based monitoring.
This analysis of real-world claims data shows lower rates of stroke, thromboembolism, and major bleeding, as well as fewer emergency department visits, with patient self-testing compared to office-based/lab INR monitoring. Our finding that PST is safe and effective among current users suggests that more patients may benefit from its use.
