| Outcome | Very elderly | Younger | P value |
|---|---|---|---|
| Discharged to chronic care/nursing home (survivors) | 20.1% | — not stated in the abstract | P < 0.001 |
| Relative reduction per year in risk-adjusted mortality | 6.3% (95% CI 5.9%–6.7%) | 4.0% (95% CI 3.7%–4.2%) | P < 0.001 |
| Mortality trend, unplanned ICU admissions (subgroup)Improved faster in very elderly | P < 0.001 | ||
| Mortality trend, elective surgical ICU admissions (subgroup)Similar improvements in both groups | P = 0.45 |
— not stated in the abstract
ICU and hospital LOS, ICU readmissions
- Very elderly stayed fewer days in ICU, longer in hospital, more ICU readmissions
Proportion of very elderly ICU admissions over time
- No change over the study period
