Multivariable model of survival in the derivation cohort (n = 449 patients with complete data, 103 died)
| Variablea | HR | 95% CI |
|---|---|---|
| SQ, not surprised versus surprised | 2.71 | 1.75 to 4.17 |
| Albumin (HR expressed for a 1-U increase) | 0.27 | 0.15 to 0.50 |
| Age (yr; HR expressed for a 10-yr increase) | 1.36 | 1.17 to 1.57 |
| PVD, yes versus no | 1.88 | 1.24 to 2.84 |
| Dementia, yes versus no | 2.24 | 1.11 to 4.48 |
↵a The age range for model development was 16 to 92; albumin range was 1.7 to 5.0. This model should not be applied to cases with ages or albumin values beyond these ranges. Albumin values <3.0 were recoded to 3.0 and values >4.5 were recoded to 4.5 for the model derivation.
