Predicting prolonged intensive care unit length-of-stay following coronary artery bypass surgery

Abstract

Introduction: Intensive Care Unit (ICU) length-of-stay (LOS) following coronary artery bypass grafting (CABG) is influenced by patient condition and operating room events. Prolonged ICU LOS is associated with increased morbidity and costs. We developed a model to predict prolonged ICU LOS (>120 hours) based on the patient's condition at ICU admission. Methods: 2787 patients underwent primary or re-operative CABG between 1/1/93 and 3/31/94, either isolated or combined with other cardiac surgery. Characteristics of the 266 patients with ICU LOS >120 hours were compared to those with shorter ICU LOS. Factors significant at p 120 hours. Multiple logistic regression identifies 11 independent predictors, including use of intra-aortic balloon pump, emergency...
