About
The pneumonia severity index (PSI) is also known as the PORT score, PORT being a subset of the validation cohort. It was derived based on data from 14,199 adult patients and subsequently validated on over 40,000 patients in the United States and Canada. HIV-positive patients and those with a recent admission for pneumonia were excluded. A simpler score, known as the CURB-65 score, has also been prospectively validated. A comparison between these two scoring systems demonstrated a slightly better performance using the PSI compared to the CURB-65 score, however the clinical utility of this difference is likely small.
