Abstract

Intracranial hemorrhage (ICH) is a complication of warfarin-associated anticoagulation resulting in significant morbidity and mortality. The purpose of this study was to assess whether interhospital transfer delays the administration of 4-factor prothrombin complex concentrate to patients with warfarin-associated ICH. This was a retrospective cohort study of all patients presenting to a 60,000 visit academic ED between August 2013 and July 2017 requiring emergent anticoagulation reversal for warfarin-associated ICH. Patients were divided into 2 cohorts: (1) transfer patients who arrived at the academic center after receiving care in a local community hospital and (2) control patients who presented directly to the academic center ED. The primary outcome was time to administration of 4-factor prothrombin complex concentrate. Secondary outcomes included hematoma expansion, guideline-adherent vitamin K administration (10mg IV), intensive care unit and hospital length of stay, disposition at discharge, and in-hospital mortality. This study included 203 patients (177 transfer patients, 26 control). The median time to arrival in transfer patients was 186 minutes (IQR 145-242). The median time to administration of guideline-adherent th...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
