NCOG-17. THE COMBAT PROJECT - CORE POST OPERATIVE MORBIDITY SET FOR PAEDIATRIC BRAIN TUMOURS

Abstract BACKGROUND Brain tumours are associated with high morbidity both from the tumour and the medical and surgical interventions used to treat them. Post operative morbidity reporting following surgery for paediatric brain tumours is poor due to the lack of a common language when reporting harms. One solution is to develop a core outcome set to stipulate the minimum post operative adverse outcomes that should be reported. The COMBAT (Core Post Operative Morbidity Set for Paediatric Brain Tumours) Project will develop a core outcome set that can be applied to post operative paediatric brain tumour patients to harmonise how adverse outcomes are measured and reported, enabling comparison between different trials, studies and clinical services. We aim to generate interest in The COMBAT Project and invite participation in the project from healthcare professionals and researchers experienced in paediatric neuro-oncology for the consensus process. METHODS AND ANALYSIS We will engage with national and international stakeholders including patients and their carers, healthcare professionals and researchers. A systematic review will identify harms reported in post operative paediatric brain tumour patients and how they are measured. Qualitative interviews with patients and carers will identify any harms of importance to them. A Delphi survey will be created from the harms identified. A consensus meeting will be held to finalise the core outcome set. The final core outcome set will be published and disseminated to encourage uptake. DISCUSSION There is a clear need for a common language to harmonise measurement and reporting of harms following surgery for paediatric brain tumour patients. This project will define post operative adverse outcomes that are of critical importance to key stakeholders. It will be used to standardise surgical morbidity outcome measurement and reporting in trials, studies and clinical practice and will inform future research in this field.
