Key result
Supratherapeutic INR occurs in ~16% of anticoagulated epistaxis patients, supporting routine testing.
Why the study?
Patients using anticoagulative medication are at increased risk for epistaxis, but the role of prothrombin time and INR testing in these patients was not well evaluated.
Observational (n=591)
No takes yet. Share an insight, caveat, or question.
INR testing in anticoagulated epistaxis patients may refine reversal decisions; leaves open whether it improves outcomes.
Soyka et al. (2013) conducted an observational in Epistaxis (n=591). Oral anticoagulation was evaluated on INR above therapeutic levels. Among epistaxis patients on oral anticoagulation, 16% presented with an INR above therapeutic levels, prompting a recommendation for routine testing in this group.
