BACKGROUND: Guidelines recommend on-site surgery backup (SB) when elective percutaneous coronary intervention (PCI) is performed. The evidence for this recommendation is however weak. OBJECTIVES: The objective of the present study was to compare clinical outcomes in patients undergoing PCI in hospitals with SB or without surgery backup (non-SB). METHODS: Prospective German PCI registry in 36 hospitals throughout Germany. Consecutive procedures were collected and analyzed centrally. RESULTS: In 2006, a total of 23,148 patients were included; 12,465 patients (53.8%) in 11 hospitals with SB and 10,683 patients (46.2%) in 25 hospitals without on-site cardiac SB. Both patient groups were well-balanced with regard to age and gender. SB hospitals had more patients with ACS (OR 1.29; 95%CI 1.23-1.36) and less patients with stable angina (OR 0.78; 95%CI 0.74-0.82) than non-SB hospitals. There was no indication of a clinically relevant differential outcome for in-hospital death, MACE, non-fatal MI, non-fatal stroke/TIA, or emergency CABG between SB and non-SB hospitals for neither patients with ACS nor stable angina except for emergency CABG in ACS patients (more frequent in SB hospitals, OR 2.29; 95%CI 1.02-5.13). CONCLUSIONS: There was no evidence of an excess risk associated with PCI-procedures performed in non-SB hospitals.
