We sought to develop a predictive model based exclusively on preoperative factors to identify patients at risk for PrlICULOS following coronary artery bypass grafting (CABG). Retrospective analysis was performed on patients undergoing isolated CABG at a single center between June 1998 and December 2002. PrlICULOS was defined as initial admission to ICU exceeding 72 h. A parsimonious risk-predictive model was constructed on the basis of preoperative factors, with subsequent internal validation. Of 3483 patients undergoing isolated CABG between June 1998 and December 2002, 411 (11.8%) experienced PrlICULOS. Overall in-hospital mortality was higher among these patients (14.4% vs. 1.2%, PF0.0001). The following variables were found to be independent predictors of PrlICULOS: increased age, recent myocardial infarction, preoperative renal failure, cerebral andyor peripheral vascular disease, chronic obstructive pulmonary disease, ejection fraction -40%, previous CABG, triple-vessel andyor left main disease, NYHA class IV symptoms and urgent or emergent status. Subsequent validation of this model demonstrated a c-statistic of 78%. An internally-validated, risk predictive model of PrlICULOS in patients undergoing CABG was constructed. Based on preoperative clinical factors, a scorecard was developed allowing identification of these patients prior to surgery and allowing for strategies aimed at optimizing hospital resources. 2009 Published by European Association for Cardio-Thoracic Surgery.

Institutional report - Cardiac general Predicting prolonged intensive care unit length of stay in patients undergoing coronary artery bypass surgery - development of an entirely preoperative scorecard

We aimed to investigate the factors affecting the length of intensive care unit (ICU) stay in patients undergoing isolated on-pump coronary artery bypass (CABG). We also aimed to evaluate effective factors on morbidity, mortality, and survival among patients with prolonged ICU stay. Between January 2002 and December 2009, a total of 1,657 patients underwent isolated on-pump CABG in our clinic. Prolonged ICU stay (>2 days) was present in 532 patient (32.1 %). Diabetes (OR 1.49, P = 0.006), hypertension (OR 1.37, P = 0.029), chronic obstructive pulmonary disease (OR 9.06, P  3 units) (OR 3.23, P = 0.007) were the independent predictive factors of prolonged ICU stay (>2 days). Postoperative mortality rate was 7 % (n = 37) and 2.3 % (n = 26) in patients with length of ICU stay >2 days and length of ICU stay ≤2 days (P  2 days (P < 0.0001). Postoperative mortality was higher in patients with prolonged ICU stay. Mean follow-up was shorter in patients with prolonged ICU stay.
