Authors' conclusions: age-specific assessment is important in the evaluation of acute asthma or reactive airway exacerbation. Diastolic hypotension may serve as an early warning indicator of severity of disease and need for hospitalization. The variability of vital signs as a predictor of hospitalization in different age groups, requires the development or refinement of assessment tools age-related acute asthma.
Reviewers' commentary: the ability to accurately predict the need for hospitalization by measuring objective parameters obtained in triage, would optimize care and improve patient outcomes. However, this study presents under review presents many methodological problems that limit their internal validity and generalizability of their results.
