Episode notes
Underdiagnosed PE
- PE is often underdiagnosed in the ICU, found in 7-27% of autopsies.
- DVT rates are high (13-32%) without prophylaxis, but significantly lower (5-9%) with it.
Number Needed to Treat
- The ARTEMIS trial compared fondaparinux to placebo in critically ill patients.
- It revealed a number needed to treat of 20 to prevent one VTE.
Padua Score
- Use the Padua score to assess VTE risk in hospitalized patients.
- Scores above 3 indicate high risk and suggest the need for chemoprophylaxis.
