Procedure Characteristics and In-Hospital Outcomes by Operator Volume
Nearly one-half of all operators were low-volume operators (performed <50 percutaneous coronary interventions [PCI] per year). Compared with intermediate- (50 to 100 PCIs per year) and high-volume operators (>100 PCIs per year), low-volume operators worked at lower volume hospitals, performed more emergency PCIs and primary PCIs for ST-segment elevation myocardial infarction (STEMI), less frequently used radial access, and used more radiographic contrast dye and fluoroscopy minutes. Although in-hospital mortality was low (1.6% overall), it was higher for low- and intermediate-volume operators than for high-volume operators.
