- The study questions whether the traditional 5.5 cm threshold for elective AAA repair in men is still cost-effective given contemporary data suggesting lower rupture risks.
- Using a Markov model, the analysis found that the cost-effectiveness of EVAR and OSR depends on annual rupture risk and willingness-to-pay thresholds (e.g., $100,000/QALY vs. $40,000/QALY).
- At current lower estimated rupture risks (e.g., 0.4% annually), the cost per QALY gained with EVAR was $1,233,000, and OSR led to a loss of QALYs, indicating the 5.5 cm threshold may not be optimally cost-effective.
