Prevalence and Several Factors Associated with Deep Vein Thrombosis in Medically Ill Patients at Prof. Dr. I.G.N.G Ngoerah Hospital, Denpasar

Introduction Venous thromboembolism (VTE) which commonly manifests as deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common problem in hospitalized patients. Approximately 60% to 70% of all reported VTE events occur in medically ill patients. Risk factors for DVT in medically ill patients include age, gender, comorbidities including diabetes mellitus, malignancy, congestive heart failure, chronic obstructive pulmonary disease, prophylactic use, and critical illness. Method This study is a cross-sectional analytical study on 100 hospitalized medically ill patients at Prof. I.G.N.G. Ngoerah General Hospital, Denpasar from May 2025 to August 2025 [ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ] [ 6 ]. Results The prevalence of DVT in this study is 39%. Most of the samples were more than 60 years old (53.8%). Based on gender, most of the samples were male (53.8%), with 10.3% of the samples categorized as obese. In this study, more than half of the DVT population experienced immobilization (59%). Infection was experienced by 64% of the samples. Based on comorbidities, 59% of the samples had chronic kidney disease, followed by heart failure (41%), cancer (41%), diabetes mellitus (30.8%), and stroke (17.9%). Linear regression analysis showed that factors independently associated with the occurrence of DVT were immobilization (p=0.04), infection (p=0.05), heart failure (p=0.02), and cancer (p=0.01). Conclusion The prevalence of DVT in hospitalized medically ill patients at Prof. Dr. IGNG Ngoerah General Hospital is 39%. Factors independently associated with DVT in medically ill patients include immobilization, infection, heart failure, and cancer. This result shows DVT is a clinical problem that requires special attention in this population. Publication History Article published online: 17 February 2026 © 2026. Thieme. All rights reserved.
