What this trial studies
This observational study aims to assess the prevalence, risk factors, and consequences of chronic post-surgical pain in children aged 0-16 years. It involves a multi-centre, international approach where participants will complete a series of questionnaires at various timepoints, starting before surgery and continuing up to one year post-surgery. The study focuses on common paediatric surgeries and evaluates factors such as anxiety and pain experiences that may contribute to chronic pain outcomes. The findings will help inform clinical practices to reduce the risk of chronic pain in children following surgery.
Why it matters
Potential benefit: If successful, this study could lead to improved guidelines for managing post-surgical pain in children, enhancing their quality of life.
How similar studies have gone: While there have been studies on post-surgical pain in adults, this specific focus on children and the longitudinal approach is relatively novel.
