Abstract
Objective: To characterize the risk of venous thromboembolism (VTE) and evaluate the use of pharmacological thromboprophylaxis in hospitalized clinical patients. Methods: A descriptive, cross-sectional, and retrospective study conducted between May and July 2023 with 140 adult patients in the internal medicine unit of a university hospital. The Padua Score was used to assess VTE risk, and the IMPROVE score was used to evaluate bleeding risk. Data were collected from medical records, and statistical analysis was performed using Microsoft Excel. The study was approved by the Ethics Committee under number 79263324.8.0000.5086. Results: Most of the hospitalized patients (80%) had at least one VTE risk factor, with heart/respiratory failure being the most common (22%). However, VTE risk stratification was neglected in 98% of cases, compromising adequate prevention. Additionally, the analysis of thromboprophylaxis prescriptions revealed a high non-compliance rate (80%), particularly regarding therapy indications. Conclusion: The lack of VTE risk stratification and inadequate prophylaxis highlight the urgent need for standardized protocols for clinical patients to improve patient safety. Furthermore, the role of the clinical pharmacist in the rational use of anticoagulants is crucial for optimizing care.
