ObjectivesIn accordance with the rising prevalence of octogenarians undergoing cardiac surgery, these patients utilize an increasing portion of intensive care unit (ICU) capacities, provoking economic and ethical concerns. In this study, we evaluated the outcomes and costs generated by the prolonged postoperative ICU treatment of octogenarians.MethodsBetween July 2009 and August 2010, 109 of 1063 patients required ICU treatment of at least 5 days after cardiac surgery. Patients were retrospectively assigned to either Group A (age <80, n = 86) or Group B (age ≥80, n = 23). Operative risk, mortality, length and costs of ICU treatment were analysed and compared. After 1 year, survival, quality of life (QOL) and functional status were assessed.ResultsHospital mortality was 31.4% in Group A and 56.5% in Group B. Survivals of discharged patients after 1 year were 83% (Group A) and 80% (Group B), respectively. Log EuroSCORE I of octogenarians was significantly higher (30 ± 17 vs 20 ± 16, P < 0.001). No significant differences (Group A vs Group B) were found between the groups concerning length of ICU treatment (20 ± 21 vs 16 ± 14 days, P = 0.577) or costs (27 205 ± 29 316€ vs 21 821 ± 16 259€, P = 0.812). Functional capacity, calculated by using Barthel index, was high (Group A: 87 ± 22 and Group B: 67 ± 31, P = 0.108) and did not differ significantly between groups. QOL, measured with the short form-12 health survey, did not differ significantly between groups (physical health summary score: P = 0.27; mental health score: P = 0.885) and was comparable with values of the age-adjusted general population.ConclusionsPresented data propose that advanced age is correlated with a higher mortality, but not with prolonged ICU treatment or higher costs after cardiac surgery. Considering the encouraging functional status and QOL of the survivors, the financial burden caused by octogenarians is justified.
