Indications are from Tables 1.2 and 1.3 in the AUC document (7). AUC = appropriate use criteria for diagnostic catheterization; GXT = stress echocardiographic testing; LV = left ventricular.

The comparison of appropriateness between interventional and noninterventional physicians was statistically significant (P < 0.001), as was the comparison among the 3 types of hospitals (P < 0.001). The comparison of proportions of patients with obstructive CAD between physician and hospital types was also statistically significant (P < 0.001). “Intervent” refers to a physician who performs both diagnostic catheterization and PCI. “Nonintervent” refers to a physician who performs only diagnostic catheterization. “Cath” refers to a hospital that performs only on-site diagnostic catheterization, “Cath and PCI only” refers to a hospital that also performs on-site PCI but not CABG, and “Cath, PCI, and CABG” refers to a hospital that also performs on-site CABG. CABG = coronary artery bypass grafting; CAD = coronary artery disease; PCI = percutaneous coronary intervention. Figure Legend: Copyright © American College of Physicians.
