Aim: Children often fall sick, which causes concern among parents. Online health information can be confusing and difficult to understand. We aimed to produce simple, informative video tutorials on the symptoms ill children present. Methods: We used a modified Delphi method to produce video tutorials on the symptoms of fever, vomiting and diarrhoea, abdominal pain, breathing difficulties, sore throat, red eyes, earache and rash. We identified the most common symptoms in acutely ill children. During the first consensus round, experts rated statements on out-of-hospital management from existing health information. Video tutorials were produced from statements rated to be included. The second consensus round involved video showings and editing. Two videos were evaluated in focus groups by parents. Results: During the first round, experts rated a median of 79 (40–154) statements for each symptom. Panels consisted of a median of seven (6–11) experts, primarily. Panels reached a consensus on inclusion, neutrality or exclusion in 83% of statements. The second round led to adjustments to the videos and final approval by experts. Most parents evaluated the videos as ‘informative, easy to understand and calming’. Conclusion: We produced video tutorials on the common symptoms ill children present using a modified Delphi method. Feedback from parents in focus groups was positive.
