Hypothesis

Preoperative screening for thrombophilias in free flap candidates may be cost-effective.

Conclusion

Preoperative thrombophilia screening may be a cost-effective measure for preventing thrombotic complications in free flap surgery.

Supporting Evidence

  • The thrombotic complication rate was found to be 4.9%.
  • A full thrombophilia screen breaks even when complication costs exceed $57,000 per patient.
  • A limited screen breaks even at $39,000.
  • 73% of flap thromboses are estimated to be attributable to thrombophilia.

Takeaway

This study looks at whether testing patients for blood clotting disorders before surgery can save money by preventing complications.

Methodology

The study used a retrospective review of free tissue transfers and developed a cost-effectiveness model based on complication rates and screening costs.

Potential Biases

Potential bias due to reliance on subjective assessments of complications and assumptions in the model.

Limitations

The study's thrombotic complication rate was based on subjective assessments, and the model relies on several assumptions that may not be accurate.

Participant Demographics

Patients undergoing free tissue transfer surgery at Brigham and Women's Hospital.
