Validation of a multicenter registry database of intra-aortic balloon pumping in a variety of clinical settings
The Benchmark Counterpulsation Outcomes Registry is a computerized database that incorporates prospectively gathered data on indications for intra-aortic balloon counterpulsation (IABP) use, patient demographics, concomitant medications and in-hospital complications and outcomes. This report summarizes the validation of the Benchmark Registry. Three audits were performed on the Registry data - the first by the sponsor and the second two by independent auditors. The data for categorical variables that could be answered by checking a box were extremely robust, with most items having at least a 95% agreement rate (except catheter size, which had an 82% agreement rate). The data were slightly less robust for quantitative variables that required a written answer (at least an 80% agreement rate). This high agreement rate supports the conclusion that the Benchmark Counterpulsation Outcomes Registry data are generalizable and suggests that the Registry is a powerful tool for tracking the evolving practice of IABP use, including indications, insertion characteristics, duration, complications and outcomes in patients undergoing IABP.
