Now, what is a CURB-65 score?
en.wikipedia.org
CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia and infection of any site.
The risk of death at 30 days increases as the score increases:
0—0.7%
1—3.2%
2—13.0%
3—17.0%
4—41.5%
5—57.0%
