The article presents information on a study published in the "American Journal of Medicine," which compared the Pneumonia Severity Index with the scores of "Confusion, urea nitrogen, respiratory rate and blood pressure" (CURB). More than three thousand patients with community acquired pneumonia were assessed between January and December 2001 in 32 emergency departments in Connecticut and Pennsylvania. Patients were assessed according to the criteria of the Pneumonia Severity Index, CURB, and CURB-65 and then stratified into risk groups. Statistical analysis was performed to assess 30 day mortality and the accuracy of the risk classification based on sensitivity, specificity, likelihood ratios, and predictive values. The results indicated that the Pneumonia Severity Index stratified more patients as low risk than CURB or CURB-65.
