EGRIS (GBS respiratory-failure risk)
Erasmus GBS Respiratory Insufficiency Score: a 0-7 estimate of the risk of mechanical ventilation within the first week of Guillain-Barre syndrome, from days between onset and admission, facial/bulbar weakness, and the MRC sum score.

Example
- Days from onset to admission
- 3 days or fewer (+2)
- Facial and/or bulbar weakness
- Yes
- MRC sum score band
- 30-21 (+3)
Result: EGRIS 6/7: a high score (5 or more) -- about a 65% risk of needing mechanical ventilation within the first week.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Risk
- mechanical-ventilation risk in week 1: low (0-2) ~4%, intermediate (3-4) ~24%, high (>= 5) ~65%. Category rates only; no per-score table is published.
What you enter
- Days from onset to admission (>7 / 4-7 / <=3)
- Facial and/or bulbar weakness
- MRC sum score band
How this is calculated
- Components
- days from onset to admission (> 7 d 0, 4-7 d 1, <= 3 d 2), facial/bulbar weakness (+1), and MRC sum-score band (60-51 0 ... <= 20 4); total 0-7.
