In hip fracture management, coagulation studies are most useful for assessing which risk, particularly if the patient is taking anticoagulants?

• A. Bleeding risk, especially if on anticoagulants.
• B. Infection risk during surgery.
• C. Risk of thromboembolism.
• D. Difficulty achieving fracture healing.

Answer: (A)

The main idea is that coagulation studies test how well the blood clots, which directly relates to bleeding risk during and after surgery. In hip fracture care, many patients are on anticoagulants, so tests like INR/PT reveal the effect of warfarin, aPTT shows heparin activity, and platelet counts assess platelet-driven clotting. If these tests indicate a higher bleeding tendency, you can plan reversal or adjustments to anticoagulation to minimize intraoperative and postoperative bleeding and the need for transfusion.

Infection risk, thromboembolism risk, and delayed fracture healing are not determined by standard coagulation studies. Infection relates to surgical technique and overall host factors; thromboembolism risk is influenced by immobility and anticoagulation management rather than current coagulation test values; healing depends on bone biology and stability rather than coagulation status.
