A recent study highlighted the challenges we face managing ED patients on warfarin therapy. Some key observations about how we're doing:
- Only 71% of patients on warfarin had an INR checked
- Nontherapeutic INRs were recorded for 49%; ED providers intervened to address these results in 21% of cases
- 71% of patients with a supratherapeutic INR received an intervention compared with 9% of patients with a subtherapeutic INR
- 30% of patients received or were prescribed potentially interacting medications
- Recommendations for specific anticoagulation follow-up were documented for only 19% of all patients
Literature continues to show warfarin is the most dangerous medication for our patients. Meticulous monitoring and follow up will help us potentially avoid serious interactions and adverse events.
