Objective To evaluate the accuracy of soluble triggering receptor expressed on myeloid cells-1 ( sTREM-1) as a diagnostic index for ventilator-associated pneumonia ( VAP) .
Methods We searched the PubMed, EMBase, Cochrane Library,Wanfang Database, CNKI and VIP for clinical trials which assessed the diagnosis accuracy of sTREM-1 for VAP. The methodological quality of each study was assessed by the quality assessment for studies of diagnostic accuracy ( QUADAS) tool. The Meta-disc software was used to conduct merger analyses on sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio. The heterogeneity test was performed and summary receiver operating characteristic ( SROC) curve was completed.
Results 8 studies were included ( 180 VAP patients and 224 non-VAP patients) . The value of merger sensitivity, specificity, and diagnostic odds ratio were 0. 80, 0. 74, and 13. 89, respectively. The area under of SROC curve was 0. 857, with Q point at 0. 788.
Conclusion sTREM-1 showed moderate accuracy for VAP diagnosis in adult mechanically ventilated patients, which should be combined with other diagnostic markers to further improve the sensitivity and specificity.
