Abstract

PURPOSE: Considerable variation exists in hospital admission rates for patients with community-acquired pneumonia (CAP). The objective of this study was to evaluate whether the pneumonia severity index (PSI) could be applied to patients with CAP as a method for triage in an emergency medical center.
METHODS
A total number of 110 patients admitted with community-acquired pneumonia between January 1997 and September 2001. Their medical records were reviewed, with pneumonia severity index, and other risk factors, the time to resolution, and the results of treatment being evaluated.
RESULTS
The pneumonia severity index accurately identified the patients with community-acquired pneumonia. Factors we evaluated were related to significant differences statistically, including such as PaCO2, WBC count, suffered lobe count, hypoxic index (PaO2/ F i O2), diabetes, hypertension, number of coexisting illness, period of admission and intravenous antibiotic therapy, and aggravated PaO2. If body temperature was less than 38.5 degrees C, it was considerable for outpatients clinics in Class I and II.
CONCLUSION
The pneumonia severity index was a useful screening tool for patients with community-acquired pneumonia. Admission and an active therapeutic plan could be recommended for patients assigned to Class III. Inappropriate admissions were reduced to 27.3% by modified triage algorithm.
