The Prevalences, Risk Factors, and Lengths of Hospital Stay of Patients with Suspected Lower Limb Deep Venous Thrombosis in the King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia

The prediction of risks and the predisposing factors that lead to the formation of blood clots, using appropriate clinical examination is crucial to the treatment of thrombosis. It is important to estimate the length of hospital stays of those clinically suspected of thrombosis. This study evaluated the prevalence of lower-limb deep venous thrombosis and its associated risk factors to predict the lengths of hospital stays of the patients. The 1,201 medical records of patients, aged 16 to 98 years, were collected from the King Abdulaziz University Hospital from January 2013 to December 2015. Their thrombosis were evaluated using a doppler ultrasound and a sonographic assessment. The results of the study revealed the prevalence of thrombosis among 18.9% of the elderly patients, 14.5% in patients with diabetes mellitus, 13.3% in those with hypertension, 17.8% in bed-ridden patients, 12.2% in patients with ischemic heart disease, 20.5% in patients with breast cancer, 5.1% in pregnant women, and 10% in obese patients. No deep venous thrombosis was reported in patients with history of heart failure. Having breast cancer and being old were the major risk factors that were identified among the patients with lower limb deep venous thrombosis.
