p-value: p=<0.0001
There is a significant and increasing overuse of preoperative cardiac stress testing in Medicare patients without cardiac indications, contrary to ACC/AHA guidelines.
Sheffield et al. (2012) conducted an observational in Elective noncardiac surgery without cardiac indications (n=74,785). Preoperative cardiac stress testing was evaluated on Frequency of preoperative cardiac stress testing (p=<0.0001). Preoperative cardiac stress testing in Medicare patients without cardiac indications occurred in 3.75% of cases, increasing significantly from 1.72% in 1996 to 6.44% in 2007 (P<0.0001).
