Independent prognostic factors for death and need for post-hospital support at discharge on multivariate logistic regression analysis#
| Risk of death | Post-hospital support need | |
| Females versus males | 2.3 (1.5–3.6) | |
| Age ≥70 yrs | 3.7 (1.3–9.8) | 3.4 (2.1–5.3) |
| Severity index signs at entry | ||
| 0 | 1.0 | 1.0 |
| 1–2 | 5.1 (1.1–22.7) | 1.6 (0.9–2.6) |
| ≥3 | 13.1 (2.9–57.7) | 2.9 (1.7–5.1) |
| Baseline dyspnoea grade | ||
| 0–1 | 1.0 | 1.0 |
| 2–3 | 3.3 (0.7–14.9) | 1.3 (0.7–2.2) |
| 4–5 | 5.5 (1.2–24.6) | 2.1 (1.2–3.6) |
Data are presented as odds ratio (95% confidence interval). For both clinical severity index and dyspnoea grade, a dose–effect relationship is observed. #: when clinical signs of severity are aggregated in a clinical severity index based on the number of signs present at entry.
