Heparin, Enoxaparin, and Mechanical Prophylaxis Utilization Evaluation in DVT Prophylaxis in a Major Teaching Hospital in West of Iran

Background: Considering the high prevalence and risk of Deep Vein Thrombosis (DVT) and pulmonary thromboembolism (PTE) in hospitalized patients and the existence of different prophylaxis methods in these patients, the necessity of evaluating the rational administration of heparin or enoxaparin and mechanical prophylaxis is one of the important priorities. The present study aimed to evaluate the consistency of the Heparin/Enoxaparin administration in comparison to guidelines in patients admitted to Imam Reza Hospital. Methods: In this prospective study drug use evaluation (DUE), 300 hospitalized patients receiving venous thrombosis prophylaxis were enrolled, of which 150 patients were selected from surgical wards and 150 patients from internal wards. The demographic and clinical data of patients were collected using clinical records of them. We used the checklists based on the Geneva System for patients admitted to internal wards and the Caprini Questionnaire for patients in surgical wards to evaluate whether patients had received heparin/enoxaparin prophylaxis and mechanical DVT prevention according to guidelines. Results: In the surgical ward, prophylactic treatment for venous thrombosis was administered in 85 (56.6%) patients admitted to surgical wards in accordance with the clinical guideline and in the internal ward, in 42 (28%) patients, with a significant difference between two sections (P: 0.0001). Mechanical prophylaxis, including compressive socks, was performed in 99 (66%) patients in the surgical ward and in the internal ward only in 56 (37.4%) patients, according to the guideline. Drug prophylaxis was administered in surgical wards in 116 (77.3%) patients and in internal wards, in 79 (52.6%) patients according to the guideline. Conclusion: Intravenous thrombosis prophylaxis, according to the guidelines, is more common in patients admitted to surgical wards than in internal wards. But in both sectors, statistics are far from international standards.
