Some methodological considerations when interpreting prevalence and incidence data

An assessment of the incidence and prevalence of venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), in medical-surgical intensive care unit (ICU) patients is based on 3 premises. First, although PE is the main thromboembolic outcome of interest, because it confers an increased risk of morbidity and mortality, no studies have systematically assessed the incidence or prevalence of this complication in ICU patients [1]. Consequently, DVT is used as

Risk factors for DVT in medical-surgical ICU patients

Established risk factors for DVT can be categorized as clinical risk factors, congenital hypercoagulable states, and acquired hypercoagulable states.

Summary

In medical-surgical ICU patients who do not receive DVT prophylaxis, the incidence of clinically important proximal DVT occurring during their ICU stay is between 25% and 32%, whereas the risk is, at most, between 10% and 18% in patients who receive prophylaxis. These data place medical-surgical ICU patients at lower risk for DVT compared with acute spinal cord injury, trauma, or neurosurgery patients, at comparable risk to patients who have had major orthopedic surgery, and at higher risk than

      Anticoagulants with potential for accumulation include low-molecular-weight heparins, direct factor Xa inhibitors, and direct thrombin inhibitors. Patients with renal failure also have the potential for thromboembolism10 with an increased risk of pulmonary embolism11 and a 2-fold increased risk of thromboembolism.12 An increased risk of thromboembolism is associated with a GFR below 75 mL/min/1.73 m2 and can be due to albuminuria.13
