ABSTRACT
INTRODUCTION: Deep vein thrombosis (DVT) is a medical disorder that arises when a coagulation of blood forms in a deep vein, entirely or partially blocking veins, and commonly affects the lower limb. The occurrence is fairly common worldwide and it is said to increase with age, with males being at a higher risk than females. OBJECTIVE: This study aims to determine the prevalence and risk factors of DVT among adult surgical patients in Aseer Central Hospital in the Aseer Region of Saudi Arabia. METHODS: This is a cross-sectional study involving 602 adult surgical patients hospitalized in the Aseer Central Hospital. Self-administered questionnaires were used to collect data from the respondents, and the data collected were analyzed using IBM SPSS Statistics for Windows, Version 24.0 (Released 2016; IBM Corp., Armonk, New York, United States). Statistical tests of association were used among the categorical variables. Association between variables was considered significant when p-value was less than 0.05. Binary logistic regression was performed to eliminate the effect of confounders in determining the risk factors for developing DVT among the respondents. RESULTS: The questionnaire response rate was 100%, with the mean age of the respondents being 44.2 ± 19.7 years. The prevalence of DVT was 7% (n=42). Obesity with adjusted OR (aOR) 17.9 (95%CI =5.39-59.18), hypertension with aOR 0.3 (95%CI =0.08-1.03), ischemic heart disease with aOR4.5 (95%CI =1.18-16.83), and orthopedics aOR 0.1 (95%CI=0.013-.240) were found to be independent risk factors for developing DVT among the respondents (p-value <=0.05). Other variables like diabetes, contraception, and pregnancy were not statistically associated with the development of DVT (p-value> 0.05) in these respondents. CONCLUSION: The findings of this study indicated a significantly low prevalence in comparison to Saudi Arabian research. Key risk factors included obesity (18x higher risk), ischemic heart disease, and hypertension. Surgery location, orthopedic cast, and Doppler ultrasound also influenced risk, while age and sex weren't significant predictors.
