This randomized clinical trial included 4686 caregivers who had called a medical helpline regarding their children, with the intervention group receiving video tutorials and the control group receiving telephone triage by health care professionals (usual care). Significantly more caregivers randomized to video tutorials reported high self-efficacy compared with controls with no increase in adverse outcomes in children (ambulance admissions, ICU admissions, or death) during the 72-hour follow-up period.
