A multivariate model predicts the in-hospital vascular complications after percutaneous coronary intervention (PCI) based on data derived from NCDR data.  Data was collected on 302,152 patients across 440 U.S. hospitals. As defined by the NCDR, bleeding required transfusion, prolonged hospital stay, and/or a drop in hemoglobin >3.0 g/dL from any location, including percutaneous entry site, retroperitoneal, gastrointestinal, genitourinary, and other/unknown location.
