ObjectiveOctogenarians offered complex cardiac surgery frequently experience a prolonged intensive care unit length of stay; however, minimal data exist on the outcomes of these patients. We sought to determine the rates and predictors of 1-year noninstitutionalized survival ("functional survival") and rehospitalization for octogenarian patients with prolonged intensive care unit length of stay after cardiac surgery and who were discharged from hospital.MethodsThe outcomes of discharged patients aged 80 years or more who underwent cardiac surgery with prolonged intensive care unit length of stay (≥5 consecutive days) from January 1, 2000, to December 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 rehospitalization after discharge from the hospital.ResultsA total of 80 of 683 (11.7%) discharged octogenarian patients had prolonged intensive care unit length of stay. Functional survival at 1 year was 92% and 81% for those with nonprolonged and prolonged intensive care unit lengths of stay, respectively (P < .01). Lack of outpatient physician visits within 30 days of discharge (hazard ratio, 5.18; P < .01) was a significant predictor of poor 1-year functional survival. The 1-year rehospitalization rates were 38% and 48% for those with nonprolonged and prolonged intensive care unit lengths of stay, respectively, with 41% of all rehospitalizations occurring within 30 days of initial discharge. A rural residence (hazard ratio, 1.82; P < .01) and nosocomial pneumonia during patients' operative admissions (hazard ratio, 2.74; P < .01) were associated with rehospitalization within 30 days of discharge.ConclusionsOctogenarians with prolonged intensive care unit length of stay have acceptable functional survival at 1 year but have high rates of early rehospitalization. Access to health services may influence functional survival and early rehospitalizations. These data suggest that close follow-up of these vulnerable patients after hospital discharge is warranted.Copyright © 2017 The American Association for Thoracic Surgery. Published by Elsevier Inc.
