The majority of children given IV-Mg in the emergency department (ED) are hospitalised, independent of asthma severity or degree of response to IV-Mg.1 The rationale for this practice is unknown but may be due to limited evidence whether children with a satisfactory response to IV-Mg can be safely discharged.2–4 Supplementary data [emermed-2022-212642supp001.pdf] We conducted this international survey of three paediatric emergency research networks in Canada (Paediatric Emergency Research Canada), Australia/New Zealand (Paediatric Research in Emergency Departments International Collaborative) and the UK/Ireland (Paediatric Emergency Research United Kingdom and Ireland) belonging to the international Paediatric Emergency Research Network to determine the proportion of paediatric ED physicians who agree there is adequate evidence that children with acute asthma refractory to the initial corticosteroid and bronchodilator therapy, and who attain a satisfactory and sustained response to IV-Mg, can be safely discharged home. The modified Dillman’s method5 was used for participant contact from March to June 2021. Using network membership and email lists, we invited participants by email to click on a link to complete a web-based, 25-item, two-page Research Electronic Data Capture survey (online supplemental material). The first page asked screening and demographic questions; the second page contained the survey questions. Physicians not treating children and those in training were ineligible. Following best practices for survey studies,6 study authors performed item generation, reduction, pretesting and pilot testing. Physicians were asked to rate on a 4-point Likert scale (‘strongly agree’ to ‘strongly disagree’) the extent to which they agreed that children remaining in marked respiratory distress after stabilisation therapy with bronchodilators and steroids, who then have a satisfactory and sustained response to IV-Mg (mild asthma: PRAM 2/12 points for … ER -
