Percentage of escalations resulting in a change in treatment according to normal or abnormal values of National Early Warning Score-2 parameters
| Normal | Abnormal | P value | |
| Heart rate | 116/213 (54.5) | 280/474 (59.1) | 0.258 |
| Systolic blood pressure | 266/445 (59.8) | 130/242 (53.7) | 0.125 |
| Respiratory rate | 126/242 (52.1) | 270/445 (60.7) | 0.029 |
| Oxygen saturations | 160/283 (56.5) | 236/404 (58.4) | 0.624 |
| Inspired oxygen | 71/135 (52.6) | 325/552 (58.9) | 0.185 |
| Consciousness | 350/632 (55.4) | 46/55 (83.6) | < 0.001 |
| Temperature | 270/478 (56.5) | 126/209 (60.3) | 0.354 |
Data are presented as the number of escalations leading to a change in treatment/total number of escalations (%).
P values are from a χ2 test assessing the difference between proportions.
