To assess the diagnostic accuracy of the clinical pulmonary infection score in the diagnosis of ventilator-associated pneumonia in mechanically ventilated patients.
METHODS:
We searched PubMed and the Cochrane database, and included only studies that compared clinical pulmonary infection score with quantitative microbiological analysis of samples for diagnosing ventilator-associated pneumonia. We constructed 2-by-2 tables of diagnostic accuracy from each article, and meta-analyzed the results by pooling estimates of sensitivity, specificity, likelihood ratio for positive index test, likelihood ratio for negative index test, diagnostic odds ratio, and 95% confidence intervals.
RESULTS:
Thirteen studies met the inclusion criteria. The pooled estimates for sensitivity and specificity for clinical pulmonary infection score were 65% (95% CI 61–69%) and 64% (95% CI 60–67%), respectively. The combined diagnostic odds ratio was 4.85 (95% CI 2.42–9.71) and the area under the curve was 0.748 (95% CI 0.65–0.85).
CONCLUSIONS:
The diagnostic performance of the clinical pulmonary infection score for ventilator-associated pneumonia is moderate. However, the clinical pulmonary infection score is simple and easy to perform, and may still be useful in diagnosing ventilator-associated pneumonia.
