Patient interview and review of available health records were used to determine the CTA indication. The proportions of patients within categories of appropriate (A), uncertain (U), inappropriate (I), and not covered were described and compared between the 2006 and 2010 criteria.Abstract: RESULTS: The 2010 criteria significantly reduced the proportion of uncertain (30.5%-11.4%), inappropriate (16.0%-12.9%), and no covered (12.1%-4.7%; P < 0.001) indications, while increasing the proportion of appropriate tests from 41.4% to 71%. By the 2010 criteria, appropriate indications were more likely to lead to the detection of coronary artery stenosis (11.5% vs 6.7%; P = 0.03) and complete examinations (95.0% vs 90.8%; P = 0.03).Abstract: CONCLUSION: The 2010 cardiac CT AUC update lead to more complete classification and to large shifts in the appropriateness ratings, underscoring the importance of ensuring the periodic revision of AUCs for evolving imaging technologies such that they perform optimally as quality measurement and reimbursement tools.
