Objective: To determine the efficiency of the deep venous thrombosis (DVT) prophylaxis protocol in postoperative patients due to proximal femoral fractures and to assess any statistical difference between the types of fractures. Methods: A retrospective observational study based on the analysis of patients’ medical records who underwent to a surgical intervention due to proximal femoral fractures in 2017 and 2021 at Hospital IFOR - Rede D’Or São Luiz. These patients were selected according to previously determined inclusion and exclusion criteria. A total of 99 patients were included divided by sex, age, laterality, length of stay, and death. According to the institutional protocol, was used chemoprophylaxis with low-molecular-weight heparin, associated use of pneumatic compression with compression stockings, and early gait. The DVT diagnosis was determined by clinical evaluation and imaging tests such as venous Doppler ultrasonography and laboratory tests. Results: The protocol was effective in our study. Only one (1.01%) patient developed DVT. Due to the lack of samples, we could not achieve our secondary objective. Conclusion: The institutional protocol is efficient for DVT prophylaxis and essential in these cases. Level of Evidence II, Prognostic Study.
