Aim The study aimed to estimate the proportion of patients who were evaluated for thrombosis risk and received appropriate thromboprophylaxis, if indicated, in King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Method This was a retrospective cross-sectional study conducted among inpatients from May 1 to August 31, 2020, in KAUH. Results Out of 298 pregnant women, the mean age was 32.09 +/- 5.29 years. A total of 136 (45.6%) were obese and 97 (32.6%) were overweight. There was a significant relationship between Caprini score categories and the following variables: age, body mass index (BMI), medical disease, history of deep vein thrombosis (DVT), mode of delivery, prophylaxis, and its duration (p < 0.05). Conclusion Awareness about thromboprophylaxis in reducing the risk of developing venous thrombosis has increased compared to before, with more than half of the cases receiving it regardless of the risk level. The highest risk of venous thromboembolism (VTE) was found in older women, obese women, and those with a previous history of DVT. Low -molecular -weight heparin (LMWH) was the main prophylaxis in the hospital with an average duration of three days.
