    The purpose of this study was to compare the relative cost-effectiveness of two clinical strategies for managing 4 to 5 cm diameter abdominal aortic aneurysms (AAAs) : early surgery (repair 4 cm AAA when diagnosed) versus watched waiting (monitor AAA with ultrasound size measurements every 6 months and repair if the diameter reaches 5 cm).


    We used a Markov decision tree to compute the expected survival in quality-adjusted life years (QALYs) for each strategy, based on literature-derived estimates for the probabilities of different outcomes in this model.

    We determined hospital costs for patients undergoing elective and emergency AAA repair at our center.
