[Knowledge of thromboprophylaxis-COVID-19 in healthcare professionals in Spain]

Patients suffering from coronavirus infection have an increased risk of venous thromboembolic disease (VTE) associated with COVID-19, which confers a higher risk of mortality. For this reason, it is necessary to analyze the knowledge and the different actions in the management of thromboprophylaxis in work environments.

Observational, descriptive and cross-sectional study with data collection through a Google® form with 19 questions for professionals involved in the care of COVID-19. 414 surveys were received. The quantitative variables were represented with means and standard deviation and the qualitative variables with percentages and confidence intervals.

414 surveys analyzed. 58.2% were women. The most participatory age group was 56-65 years. 95.2% stated that COVID-19 patients had a higher risk of VTE and peripheral arterial microthrombosis. 93.6% considered that outpatient COVID-19 patients should receive thromboprophylaxis. 60.5% of the physicians did not know any protocol for the evaluation of thrombotic risk in these patients. Low molecular weight heparin was considered the main treatment for thromboprophylaxis.

The majority of doctors consider that COVID-19 patients have a higher risk of suffering VTE and peripheral arterial microthrombosis than the general population, however more than a third do not assess the thrombotic risk and a significant percentage claim not to know protocols to evaluate said risk. The survey highlights the training needs of our professionals in thromboprophylaxis so that our patients receive healthcare with the highest possible quality.
