抄録: | [Background] Despite the controversy regarding its clinical utility, the PaO₂/FIO₂ ratio has been used to define the severity of acute respiratory distress syndrome (ARDS). This systematic review and meta-analysis (SRMA) details summary estimates of the predictive performance of PaO₂/FIO₂ ratio in predicting mortality in patients with ARDS. [Methods] To clarify the integrated diagnostic accuracy, we included studies in which the study population comprised patients with ARDS in any clinical setting, included adult patients (≥18 years old), and evaluated mortality. The MEDLINE and Cochrane Central Registry of Controlled Trials databases were searched for articles in English. We performed SRMA on the accuracy of the diagnostic prognostic tests using the Quality Assessment of Diagnostic Accuracy Studies-2 tool to evaluate the risk of bias. We obtained summary point estimates of sensitivity and specificity and calculated the area under the receiver operating characteristic (AUROC) curve of the summary receiver operating characteristic curve with 95% confidence intervals (CIs). [Results] Twenty-eight trials with 38270 patients were included in the quality assessment. Most of the studies were conducted in intensive-care units. Overall, the risk of bias is high. For PaO₂/FIO₂ of 100 and 200 the pooled sensitivity, specificity, and AUROC were 44.8% (95% CI, 38.1%-51.7%), 70.6% (95% CI, 65.9%-74.9%), 0.60 (0.58-0.64) and 83.9% (95% CI, 78.9%-87.8%), 26.1% (95% CI, 20.8%-32.1%), 0.64 (0.60-0.69), respectively. [Conclusion] The PaO₂/FIO₂ ratio alone did not have impressive prediction accuracy for mortality in patients with ARDS and might not be able to be used solely as a clinical prognostic tool. |
