How cost-effective is screening for abdominal aortic aneurysms?
OBJECTIVE: To provide reliable estimates of the long-term cost-effectiveness of abdominal aortic aneurysm screening in men. METHODS: A Markov health economic decision model for screening is described and extrapolated to 30 years. The strategy modelled involves a one-off scan at age 65 years, with annual and three-monthly follow-up scans for small and medium aneurysms, respectively. Referral for elective surgery occurs at an aortic diameter of 5.5 cm. Model parameters are estimated from patien...Expand abstract
