Background: Venous thromboembolism (VTE) is a leading cause of preventable morbidity and mortality in surgical patients. Despite international recommendations for standardized VTE risk assessment, there is limited implementation in many countries, including Mongolia. This study aimed to assess preoperative VTE risk using the Caprini Risk Assessment Model (Caprini RAM) and to explore its applicability in routine surgical practice.
Methods: A total of 3366 adult patients undergoing elective surgery between January 1 and June20, 2025, at the First Central Hospital of Mongolia were evaluated using the Caprini RAM. Patients were stratified into five risk categories: very low (0), low (1–2), moderate (3–4), high (5–8), and very high (≥9) risk. A two-hour training session was provided for anesthesia residents to ensure accurate scoring and data collection. Data were analyzed using SPSS version 26.
Results: Of the 3366 patients, 0.39% were classified as very low risk, 33.5%as low risk, 46.1% as moderate risk, 18.2% as high risk, and 1.81% as very high risk. The highestrisk surgerieswere predominantly found joint replacement (15%), liver (14.3%), and kidney transplantation (5%). In contrast, low-risk profiles were mostly observed in ophthalmic, maxillofacial, and ENT surgeries. The preparatory training contributed to consistent data entry and improved awareness of VTE risk assessment among anesthesia residents.
Conclusions: The Caprini RAM proved feasible for preoperative VTE risk stratification in a high-volume surgical center in Mongolia. Its use revealed that a substantial proportion of patients were at moderate to high risk, warranting targeted prophylaxis. Incorporating the Caprini RAM into routine surgical care could enhance patient safety and guide evidence-based thromboprophylaxis protocols in Mongolian healthcare settings.
