Approximately 1 in 4 (24.9%) children are overweight or obese.1The health risks associated with paediatric obesity are considerable, children with obesity have higher risk of remaining obese as an adult 2and having serious health outcomes in later life.1, 3, 4Primary care providers do believe that weight management in children is part of their role, however only a small proportion regularly provided counselling.5, 6Most children who are overweight or obese do not receive evidence-based care7, therefore it is essential that novel strategies are used to improve service delivery. Project ECHO® (Extension for Community Healthcare Outcomes) is a hub-and-spoke platform that utilises telementoring to help facilitate the professional development of health professionals and empower them to provide care for patients that they would otherwise need to refer on. Sessions are delivered by experts in the field and include didactic as well as case-based learning. This research project aimed to evaluate the effectiveness of the Childhood Overweight and Obesity Project ECHO® series. Participants of the ECHO® series were invited to complete an specially designed online questionnaire pre and post completion of the course to assess changes in knowledge, attitudes, confidence and practice behaviours in managing childhood overweight and obesity. Sixty-nine participants completed the questionnaire, 24 participants were eligible and consented, 17 of which have provided both pre and post course responses. Preliminary analysis of responses shows significant improvement in attitudes, confidence and practice behaviours, including increased knowledge of the important elements of counselling (p= 0.001), increased confidence in raising the topic of obesity (p= 0.038), collaboration with (p= 0.013) and empowering children and families (p= 0.003), and initiating appropriate follow up (p= 0.026). Telementoring provides a unique method of educating and supporting health professionals, and building and optimising capacity to effectively manage children with overweight and obesity in their local setting.
