The pneumonia severity index (PSI) is a clinical prediction rule to estimate the probability of complications among patients with community acquired pneumonia.[1]
The accuracy of the PSI has been independently validated by other researchers.[2]
Patients with PSI Risk groups I-III can usually be treated as an outpatient.[3]
A randomized controlled trial found that use of the PSI to guide management of community acquired pneumonia improved medical care by reducing resource consumption without reducing quality of care.[4]
Removing the effect of age may improve accuracy.[5]
The pneumonia severity index has been compared to the CURB-65 in predicting mortality.[2]
