Background: Non-invasive, rapid, and precise assessment of injury in the military settings is extremely important, but difficult. Focused Assessment with Sonography in Trauma (FAST) has been increasingly employed for assessing the location and severity of injury and guiding further treatment decision.
Aims: However, the evidence regarding utility of FAST in the military settings is scattered. We conducted a meta-analysis to evaluate the diagnostic performance of FAST for assessing injury in the military settings.
Study Design: Meta-analysis study.
Methods: We identified all relevant papers via the PubMed, EMBASE, and Cochrane Library databases. We evaluated the quality of included studies by the QUADAS-2 tool. We pooled the area under curve (AUC), sensitivity, specificity, positive and negative likelihood ratio, and diagnostic odds ratio as the effect sizes. We evaluated the heterogeneity by P value and I2.
Results: Six papers were included. The AUC of FAST for assessing the injury was 0.85. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 0.66, 0.98, 33.1, 0.34, and 97, respectively. The heterogeneity among studies was statistically significant (P=0.006, I2=78%).
Conclusion: FAST is potentially valuable for assessing the injury in the military settings. Due to its high specificity, FAST may be approriate to rule in significant injury. However, due to its poor sensitivity, the ability of FAST to rule out injury cannot be relied upon.
