Abstrakt: Aim: The aim of this retrospective study was to evaluate the use and appropriateness of preventive measures for venous thrombosis among adult inpatients in a Benin teaching hospital.
Patients and Methods: All patients were systematically enrolled. The risk of venous thrombosis was estimated according to international guidelines. Thromboembolic events were diagnosed using the Wells score and, when possible, by paraclinical investigations. The following variables were studied: the risk of venous thrombosis, the use and appropriateness of preventive measures, and the frequency of thromboembolic events. The data were analyzed with Epiinfo 6.04.fr and SPSS software, and significance was assumed at p=0.05.
Results: The study population consisted of 487 patients recruited in four surgical wards, four general wards and one obstetric-gynecology ward. Mean age was 38.7+/-11.3 years and the sex ratio 0.51. The risk of thrombosis was considered low in 15% of patients, moderate in 60.8%, high in 21.1% and very high in 3.1%. Prophylactic measures were prescribed to 33.9% of the patients overall, 53.6% in the obstetric gynecology ward, 28.5% in the surgical wards and 12.9% in the general wards. The frequency of preventive measures rose with the level of risk (p<0.0001). Preventive measures consisted of passive mobilization, aspirin, enoxaparin and acenocoumarol. The prescriptions were appropriate in only 6% of cases. Among 198 patients who were monitored for two months after hospital discharge, 8% had a venous thromboembolic event. Such events were more frequent in the absence of prophylaxis (12% vs 3.3%, p=0.02).
Conclusion: The risk of venous thromboembolic is recognized but poorly managed in this Bénin teaching hospital.
