Objective:to evaluate the accuracy of the version of the Brighton Pediatric Early Warning
Score translated and adapted for the Brazilian context, in the recognition of
clinical deterioration. Method:a diagnostic test study to measure the accuracy of the Brighton Pediatric Early
Warning Score for the Brazilian context, in relation to a reference standard. The
sample consisted of 271 children, aged 0 to 10 years, blindly evaluated by a nurse
and a physician, specialists in pediatrics, with interval of 5 to 10 minutes
between the evaluations, for the application of the Brighton Pediatric Early
Warning Score for the Brazilian context and of the reference standard. The data
were processed and analyzed using the Statistical Package for the Social Sciences
and VassarStats.net programs. The performance of the Brighton Pediatric Early
Warning Score for the Brazilian context was evaluated through the indicators of
sensitivity, specificity, predictive values, area under the ROC curve, likelihood
ratios and post-test probability. Results:the Brighton Pediatric Early Warning Score for the Brazilian context showed
sensitivity of 73.9%, specificity of 95.5%, positive predictive value of 73.3%,
negative predictive value of 94.7%, area under Receiver Operating Characteristic
Curve of 91.9% and the positive post-test probability was 80%. Conclusion:the Brighton Pediatric Early Warning Score for the Brazilian context, presented
good performance, considered valid for the recognition of clinical deterioration
warning signs of the children studied.
