Background  There is limited information on real‐world practice versus current clinical practice guidelines for oral anticoagulant reversal before emergency surgery.    Objective  To identify current practice/knowledge gaps for oral anticoagulant reversal emergency surgery among anesthesiologists.    Methods  A 22‐question survey covering aspects of clinical practice relating to oral anticoagulant reversal was sent to American Society of Anesthesiology members with weekly reminders during data collection from October to December 2018.    Results  Responses were received from 2315 anesthesiologists of which 86% of respondents were United States based. Emergency surgery was defined as occurring within 4 hours of the decision to operate by 60% of respondents. Fresh frozen plasma (FFP) was used by 75% of respondents for vitamin K antagonist (VKA) reversal and by 54% for direct oral anticoagulant (DOAC) reversal in emergency surgery and 67% in major operative bleeding. Only 32% of institutions had emergency anticoagulant reversal protocols, and 54% of respondents selected an international normalized ration (INR) ratio goal for VKA reversal of ≤1.5. Only 13% initially consulted or coordinated management with hematologists, and the final decision regarding coagulation management was made by the respondent in 26% of cases. A coordinated approach with hematologists and cardiologists was reported by 64%, and over half (51%) required approval for prothrombin complex concentrate administration for emergency procedures.    Conclusions  Despite recommendations to the contrary, FFP is extensively used for emergency VKA and DOAC reversal. There is a clear need for institutions to develop guideline‐informed recommendations/management algorithms based on input from medical professionals routinely involved in management of these patients.
