Review Meta Analysis Observational Study
Simplification of the IDSA/ATS criteria for severe CAP using meta-analysis and observational data.
The 2007 Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) guidelines proposed "minor" criteria to predict intensive care unit (ICU) admission in patients with community-acquired pneumonia. These criteria were based on expert opinion. Consequently, the authors of the guidelines asked investigators to determine whether the score could be simplified by excluding noncontributory variables. ⋯ Additional predictors suggested by the IDSA/ATS were associated with mortality and ICU admission, but only incorporating acidosis (pH <7.35) altered the AUC (0.82 (95% CI 0.78-0.86) (p=0.6) for mortality and 0.86 (95% CI 0.82-0.88) (p=0.8) for ICU admission). No improvements were statistically significant. The IDSA/ATS criteria can be simplified by removing three infrequent variables.
