Direct Oral Anticoagulants (DOACs): Current Evidence for Extended VTE Prophylaxis in Medically Ill Patients and Reversal

This activity was recorded at a satellite symposium event concurrent with the 2018 SHM Annual Conference. This educational content was developed and hosted by Horizon CME.


Program Overview

Patients hospitalized for an acute medical illness are at an increased risk for VTE. With increasingly shortened hospital stays, acutely ill hospitalized patients are at an increased risk of developing VTE both in the hospital and after discharge. Outpatient VTE episodes often occur within 30 days of hospital discharge and less than half of those discharged patients receive VTE prophylaxis. Therefore, it is important for clinicians to be able to risk stratify patients and provide extended prophylaxis for medical patients at increased risk for VTE.

This webcast will discuss the risk factors and burden of VTE and review ACCP guideline recommendations for VTE prophylaxis in acutely ill hospitalized medical patients. Faculty will assess the safety and efficacy of direct oral anticoagulants for extended VTE prophylaxis, explain the stratification of VTE and bleeding risk, as well as the process for devising evidence-based antithrombotic regimens. The presentation will also include an outline of current and emerging options for reversal of direct oral anticoagulants.

Target Audience

 Hospitalists, Internists, nurse practitioners (NPs), physician assistants (PAs) who practice in a hospital setting.  

 Learning Objectives

  1. Outline the risk factors and burden of VTE in medically ill patients post-hospitalization
  2. Review ACCP guideline recommendations for VTE prophylaxis in acutely ill hospitalized medical patients
  3. Assess the safety and efficacy of direct oral anticoagulants (DOACs) for extended VTE prophylaxis in medically ill patients
  4. Devise evidence-based antithrombotic regimens for medically ill patients taking into consideration patient specific factors that impact VTE and bleeding risk
  5. Outline current and emerging options for reversal of DOACs
