General description
There is considerable variability in rates of hospitalization of patients with community-acquired pneumonia (CAP). The pneumonia severity index (PSI) or PORT Score is a clinical prediction rule that accurately identifies patients with community-acquired pneumonia who are at low risk for death and other adverse outcomes and therefore helps physicians make more rational decisions about hospitalization of these patients.
In PSI the points are assigned based on demographic factors, coexisting illnesses, physical-examination findings and laboratory/radiographic findings identified at presentation. The resulting score stratifies the patients into 5 risk classes, each associated with an estimated mortality rate.
The 2019 Official Clinical Practice Guideline of the American Thoracic Society and Infectious Diseases Society of America on Diagnosis and Treatment of Adults with CAP recommends the PSI as the preferred validated clinical prediction rule used to determine the need for hospitalization in adults diagnosed with CAP, in addition to clinical judgment.
