 This scoping review found that there has been an increase in the number of studies involving pediatric patients in recent years. Pediatric patients, especially those with multiple conditions or oncology patients, were most commonly involved in studies in the US, UK, and Canada. Pediatric patients were most often asked to express their views on questions related to daily clinical care and the individual interview was the most frequently used method. As the scope of pediatric patient engagement increased with age, it became apparent that there is no single approach to engaging pediatric patients in healthcare.
