Prolonged intensive care unit stay in cardiac surgery: risk factors and long-term-survival.

Abstract

Risk factors have been found for prolonged intensive care unit (ICU) stay in cardiac surgery patients in only a few studies; conflicting results have been described. The focus of this study was twofold: first, to evaluate preoperative, intraoperative, and postoperative risk factors for ICU stay greater than 3 days in a cardiac surgery patient population; second, to evaluate long-term survival in cardiac surgery patients with prolonged ICU stay.
