Objetive:

To find out the characteristics of the population at risk of venous thromboembolism (VTE) and to determine whether antithrombotic prophylaxis used in nonsurgical conditions at a third level university hospital adheres to established protocols for thromboprophylaxis.

Methods:

A cross-sectional observational study was conducted. Selected patients were over 40 years of age, hospitalized due to nonsurgical, medical conditions and hospitalized for at least 72 hours. The PADUA score was used to assess the risk for VTE, and the IMPROVE score was used to assess bleeding.

Results:

The sample consisted of 233 patients, 56.6% of whom were men, with an average age of 64.8 ± 13.1 years. The main risk factor for VTE during hospitalization was prolonged immobility, at 48.9% of the total sample and 69.4% of patients with a Padua ≥4 (p=<0.01).

When determining the frequency of thromboprophylaxis in patients at risk, results showed that 79.8% received some type of thromboprophylaxis. Among patients with a <4 Padua score it was found that 73.4% received pharmacologic thromboprophylaxis.

Conclusions:

In our field, pharmacologic thromboprophylaxis is mainly based on the use of low molecular weight heparins and it can be concluded that the use of thromboprophylaxis is appropriate and above that of other previously referenced series.
