Rello J et al. PIRO score for community-acquired pneumonia: a new prediction rule for assessment of severity in intensive care unit patients with community-acquired pneumonia. Crit Care Med. DOI: 10.1097/CCM.0b013e318194b021. PMID: 19114916.

The total is 0–8. Observed 28-day mortality strata are low at 0–2, mild at 3, high at 4, and very high at 5–8. (2009)
