Abstrakt:	Background: Overuse of thromboprophylaxis is not an infrequent behavior in internal medicine. However, differently from underuse, overuse of thromboprophylaxis is rarely taken into account, and only few studies have addressed this issue. The purpose of our study was to try to understand the reasons behind this phenomenon. Methods: Using data from the TEVERE study, we evaluated 279 patients hospitalized in 21 hospitals of the Lazio Region in Italy. Only patients who were negative to major risk scores as established in the scientific literature were included. We assessed the frequency of thromboprophylaxis in acutely ill medical patients hospitalized in emergency and internal medicine wards, and we performed a comparative analysis for each risk factor among patients who received or not received thromboprophylaxis. Results: Forty-seven patients (16.5%) with negative risk scores were given thromboprophylaxis during hospitalization. On backward stepwise logistic regression analysis, severe infection (odds ratio [OR] 2.31; 95% confidence interval [CI] 1.25-4.35) and chronic venous insufficiency (OR 3.02; 95% CI 1.96-4.67) were found to be the strongest predictors of the use of thromboprophylactic treatment with heparin. The subgroup of patients who did not exhibit risk factors was also analyzed, and age was found to be the main factor in the decision-making process regarding heparin administration in the absence of other risk factors (74.9 ± 11.8 vs 63.7 ± 18.1, p=0.002). Conclusions: Our findings suggest that thromboprophylaxis is associated with considerable uncertainty, which results in its overuse. Further research is needed to better understand thromboembolic risk factors in hospitalized medical patients.
