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 (SaO 2 ) 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 SaO 2 below 90%. The area under the receiver operating characteristic ( ROC ) curve for the initial SaO 2 predicting mild disease was 0.75 (95% CI 0.53–0.97), and the optimal cut‐off value was 93%. An initial SaO 2 >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 SaO 2 ≤93%. Conclusion An initial SaO 2 >93% reflects a mild course of acute wheezing and using this cut‐off point could have almost halved hospital admissions.
