Key result
At the first primary care follow-up after hospital discharge, only 51% of patients newly initiated on warfarin maintained a therapeutic INR, with 23% subtherapeutic and 26% supratherapeutic.
Observational (n=35)
Only about half of patients newly initiated on warfarin achieve a therapeutic INR at their first post-discharge follow-up, highlighting the need for closer monitoring and intervention during transitions of care.
Highlights gaps in post-discharge anticoagulation management; leaves open whether targeted interventions improve INR control.
Purpose To determine the percentage of patients who maintain a therapeutic INR (international normalized ratio) when presenting for their first INR follow-up in the primary care setting after hospital discharge. Methods Prospective observational trial enrolling patients newly initiated on warfarin. Results Data for 35 patients were collected. Fifty-one percent of patients were therapeutic at their first follow-up lab visit with 23% subtherapeutic and 26% supratherapeutic. Conclusion A low percentage of patients were therapeutic and more intervention is necessary in the immediate post-discharge time.
