What is the evidence status of A ppropriate U se C riteria (AUC)? Insight from a matching exercise with the guidelines for echocardiography

There is interest in adapting the American Appropriate Use Criteria ( AUC ) for transthoracic echocardiography to A ustralian practice. We matched 90 of 98 AUC with the guidelines (53 appropriate, 12 sometimes appropriate, 25 rarely appropriate), but eight lacked any match. Among the matched criteria, 76 (82%) indications were concordant with the guidelines. A stronger evidence base would be desirable to settle these discrepancies before A ustralian adoption of AUC .
