Authors’ conclusions: the overall mortality rate in pediatric acute respiratory distress syndrome (ARDS) is approximately 24%. Among the studies included in the review, a consistent trend towards improvement in survival was demonstrated for those published later, comparing with those previous in time.
Reviewers’ commentary: the mortality estimated in this study is applicable to our clinical practice, except for hospitals with few cases and patients treated with surfactant. It is therefore a reference to consider when assessing the quality of care in our intensive care units. However, it does not provide risk estimates, based on the severity of the patients.
