<strong><u>DOACs and the Critically Ill</u></strong></p>
<ul>
<li>
The use of DOACs for the prevention of stroke and venous thromboembolism is increasing.</li>
<li>
Though DOACs may be non-inferior to warfarin for these indications, it is important to consider the following pearls on DOACs in the critically ill patient:
<ul>
<li>
Acute kidney injury can double the half-life of dabigatran to more than 30 hours</li>
<li>
Hepatic failure can markedly increase the half-life of the factor Xa inhibitors</li>
<li>
PT, aPTT, and INR may not accurately assess the risk of bleeding. Use dilute thrombin time (TT), ecarin clotting time (ECT), or TEG/ROTEM to assess coagulopathy</li>
<li>
Can consider PCC (25 to 50 IU/kg) for life-threatening hemorrhage. The evidence supporting this recommendation is not robust.</li>
</ul>
