In-hospital Access Site Complications in Patients on Oral Anticoagulants: A Retrospective Review of Medical Records from a Tertiary Care Center


This study is being conducted in partnership with the Midwest Cardiovascular Research Foundation.

The purpose of this study is to examine the relationship between oral anticoagulants and in-hospital access site complications.

The study team hypothesizes that a higher INR (>1.6) in patients on warfarin
and patients who remained anticoagulated on novel oral anticoagulants are at increased risk of access site bleeding or hematoma post sheath removal or periprocedurally and up to discharge from the hospital.
