The Rockall score can be divided into a preliminary score before endoscopy and a complete score after endoscopy. Different scores correspond to different mortality risks, as shown below:
| Score | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8-11 |
|---|---|---|---|---|---|---|---|---|---|
| Mortality risk before endoscopy (%) | 0.2 | 2.4 | 5.6 | 11.0 | 24.6 | 39.6 | 48.9 | 50.0 | |
| Mortality risk after endoscopy (%) | 0 | 0 | 0.2 | 2.9 | 5.3 | 10.8 | 17.3 | 27.0 | 41.1 |
The Rockall scoring system is still widely used in clinical practice to assess the risk of rebleeding and mortality in patients with acute gastrointestinal bleeding, especially for its reliability in evaluating mortality risk.
