How useful is a prediction rule to identify low-risk patients with community-acquired pneumonia?

Reference
Fine MJ, et al. A prediction rule to identify low-risk patients with community-acquired pneumonia. N Engl J Med. 1997 Jan 23;336(4):243-50.

Objective
To develop and validate prediction rule for 30 day mortality in patients with community-acquired pneumonia

Summary
The PORT score can accurately identify patients with community-acquired pneumonia (CAP) who are at low risk for mortality

Methods
From a database of patients discharged from hospitals in multiple states, data from all patients aged 18 and over hospitalized in 1989 for pneumonia, with no history of AIDS, HIV infection or previous hospitalization within 7 days prior to admission for pneumonia. Records of 14,199 patients analyzed for demographic characteristics, coexisting illnesses and physical exam findings. Validation in an analysis of discharge data from 38,000 patients hospitalized for CAP in 1991 and in a prospective cohort study (PORT Study). The PORT study enrolled patients 18 and over symptoms suggestive of pneumonia, have radiographic evidence of pneumonia within 24 hours of presentation, no history of AIDS or hospital admission within 10 days before presention of pneumonia.

Table 3 compares 30 day mortality rates for patients assigned to each of the 5 risk classes in the PORT study and the validation group
