AIM: Mild wheezing during respiratory infections is a common cause of paediatric hospital admissions. This study aimed to identify factors predicting this condition in children over six months of age.
METHODS: We reviewed the medical records of 539 children, aged 6 months to 16 years, who visited the emergency department because of wheezing during respiratory infection. Mild disease was defined as hospital stays of less than 48 h and severe disease was staying at least 48 h or being treated in intensive care. Patients with an initial oxygen saturation value (SaO2 ) below 90% were analysed separately.
RESULTS: Most (87%) of the 539 patients had mild disease, 6% had a severe disease and 7% had an initial SaO2 below 90%. The area under the receiver operating characteristic (ROC) curve for the initial SaO2 predicting mild disease was 0.75 (95% CI 0.53-0.97), and the optimal cut-off value was 93%. An initial SaO2 >93% had a negative predictive value of 93%. Although 270 patients (50%) were hospitalised, only 140 (26%) would have been admitted using an optimal cut-off of SaO2 ≤93%.
CONCLUSION: An initial SaO2 >93% reflects a mild course of acute wheezing and using this cut-off point could have almost halved hospital admissions.
