The value of prognostic indices for pneumonia.
One of the most important decisions in the management of community-acquired pneumonia is deciding the care site, which affects morbidity, mortality, and costs. Clinical judgment alone is difficult and imprecise. The Pneumonia Severity Index score and the CURB-65 (confusion, urea nitrogen, respiratory rate, blood pressure, 65 years of age and older) score are validated prognostic indices to predict mortality, and they can identify low-risk patients who may be eligible for outpatient management. However, limitations of the scoring systems preclude their isolated use, and they can only be recommended as an aid to guide hospital admission decisions. The Pneumonia Severity Index score is slightly better at identifying the lowest risk patients, whereas CURB-65 is much simpler to use. As an adjunct to clinical judgment, we consider CURB-65 to be the most useful prognostic index for identifying low-risk patients.
