The Risk Factors and Associated Socio-Demographic Profile of Deep Vein Thrombosis (Dvt) Among Patients Referred For Doppler UltrasoundImaging At Dr George Mukhari Academic Hospital

Background: Venous Thromboembolism (VTE) is one of the leading causes of cardiovascular related deaths and is a significant economic burden on the healthcare system. Early identification and correct management of patients at risk of developing DVT improves their health. Objectives: The study sought to determine the risk factors and socio-demographic profiles of Deep Vein Thrombosis (DVT) of patients referred for Doppler ultrasound imaging at Dr George Mukhari Academic Hospital (DGMAH). Methods: A cross sectional descriptive study was used to determine the risk factors and associated demographic profiles of DVT among patients referred for Doppler ultrasound imaging at DGMAH. The study used quantitative methods. A total of 135 patients participated. Patients completed a structured questionnaire to assess risk factors of DVT. They were then assessed for DVT using an ultrasound scan and results were documented. The information from the questionnaires and results was coded and entered into a computer using Statistical Package for Social Science (SPSS) Version 25. Data analysis was then conducted. Results: Of the 135 patients who were referred to the radiology department for ultrasound scanning of lower limbs between January and June 2019, 42 patients (31%) were diagnosed with DVT. Prolonged bed rest (p=0.037) and history of having recently completed TB treatment (p=0.042) were associated with development of DVT. Conclusion: Prolonged immobility and recent completion of TB treatment were associated with increased risk of developing DVT. There is need to screen these patients for DVT early and institute DVT protocols.
