Risk of death 30 and 90 days after IHT among critically ill patients with SARS-CoV-2 presented as HR with 95% CI (non-IHT as reference)
| Risk of death after IHTs | |||||||
| All patients | Exposure | Mortality | 30-day mortality | 90-day mortality | |||
| No (%) | 30-day No (%) | 90-day No (%) | Unadjusted HR with 95% CI | Adjusted HR with 95% CI | Unadjusted HR with 95% CI | Adjusted HR with 95% CI | |
| Non-IHT | 532 (80) | 136 (26) | 157 (30) | 1.0 (referent) | 1.0 (referent) | 1.0 (referent) | 1.0 (referent) |
| IHT | 133 (20) | 25 (19) | 34 (26) | 0.66 (0.43 to 1.02) | 0.47 (0.30 to 0.76)* | 0.79 (0.54 to 1.14) | 0.52 (0.34 to 0.78)* |
The models were adjusted for age, sex, body mass index categories (<30 or >30), Simplified Acute Physiology Score, Charlson Comorbidity Index (0, 1, >2), mechanical ventilation (yes/no), treatment limitations (yes/no) and SARS-CoV-2 wave (wave 1/waves 2–3).
*Statistically significant differences between groups, p<0.05.
IHT, interhospital transfer.
