Outcomes of Octogenarians Discharged from Hospital after Prolonged Intensive Care Unit Length of Stay after Cardiac Surgery

Abstract Objective Octogenarians offered complex cardiac surgery (CS) frequently experience a prolonged ICU length of stay (prICULOS); however minimal data exist on outcomes of these patients. We sought to determine rates and predictors of 1-year non-institutionalized survival (“functional survival”), and re-hospitalization for octogenarian prICULOS CS patients discharged from hospital. Methods Outcomes of discharged CS patients ≥80 years old with prICULOS (defined as ICULOS of ≥5 consecutive days) from Jan 1, 2000 to Dec 31, 2011 were examined retrospectively from linked clinical and administrative provincial databases. Regression analysis was used to determine predictors of 1-year functional survival and re-hospitalization following discharge from hospital. Results There were 80/683 (11.7%) discharged octogenarian patients who experienced prICULOS. Functional survival at 1-year was 92% and 81% for non-prICULOS and prICULOS patients respectively (p
