RT Journal A1 Shah BR, Douglas PS, Peterson ED T1 PHysician billing and cardiac stress testing patterns—reply JF JAMA JO JAMA YR 2012 FD February 22 VO 307 IS 8 SP 781 OP 783 DO 10.1001/jama.2012.190 UL http://dx.doi.org/10.1001/jama.2012.190 AB In Reply: Dr Pellikka and colleagues raise the concern that our study does not adequately test the American College of Cardiology Foundation's AUC.1- 3 We generally agree, but this was not our goal. Our objective was to assess differences in use by billing status for an indication that is common in clinical practice. We hope that in the future physician decision support tools may help guide physicians in identifying patients who meet AUC for cardiovascular testing and thereby reduce variation in testing patterns.
