    BackgroundEmergency surgery has become an increasingly rare event after percutaneous coronary intervention (PCI). There have been no randomized trials evaluating whether cardiac surgery services on-site are essential for patient safety and optimal outcomes during and after PCI.Study DesignThe MASS COMM trial (ClinicalTrials.gov no. NCT01116882) is a randomized trial comparing the safety and effectiveness of nonemergency PCI at hospitals without surgery on-site (SOS) (non-SOS hospitals) and hospitals with SOS (SOS hospitals). A total of 3,690 subjects will be randomized in a 3:1 fashion to undergo PCI at non-SOS and SOS hospitals, with follow-up at hospital discharge, 30 days, and 12 months after PCI. The rate of major adverse cardiac events (all-cause mortality, myocardial infarction, repeat revascularization, and stroke) will serve as the primary safety end point at 30 days and the primary effectiveness end point at 12 months. The design is a 1-way randomized trial with a statistical hypothesis of noninferiority of nonemergency PCI at non-SOS hospitals for both safety and effectiveness end points.ConclusionsThis multicenter, randomized trial will compare the relative safety and effectiveness of nonemergency PCI at sites with and without cardiac SOS.Copyright © 2011 Mosby, Inc.
