How is venous thromboembolism risk assessed preoperatively?

• A. Postoperative risk assessment only.
• B. Based on surgeon preference only.
• C. No prophylaxis.
• D. Use risk assessment tools (e.g., Caprini score) and provide prophylaxis (pharmacologic and/or mechanical) as indicated.

Answer: (D)

Assessing venous thromboembolism risk before surgery relies on using a validated risk assessment tool to categorize how likely a patient is to develop VTE and then applying prophylaxis tailored to that level of risk. A common example is the Caprini score, which assigns points for factors such as age, obesity, prior VTE, cancer, recent surgery, immobility, and the type and duration of the planned procedure. The total score places the patient in a risk category (low, moderate, high, or highest), and the prophylaxis plan is adjusted accordingly. Prophylaxis can be mechanical, pharmacologic, or a combination. Mechanical methods (like sequential compression devices or graduated compression stockings) reduce venous stasis and are often used when bleeding risk is high or as a complement to pharmacologic methods. Pharmacologic prophylaxis (such as low-dose heparin or low molecular weight heparin) is selected based on bleeding risk, renal function, and surgical factors, and may be started preoperatively or postoperatively depending on the situation. This approach is proactive and individualized, ensuring protection for those at higher risk while avoiding unnecessary interventions for lower-risk patients. The other options imply risk assessment happens only after surgery, is based on personal preference, or involve no prophylaxis, which misses the goal of reducing VTE with a patient-specific plan.
