ESPGHAN and NASPGHAN 2024 protocol for paediatric functional constipation treatment guidelines (standard operating procedure).

INTRODUCTION

Functional constipation is common in childhood, with chronicity leading to a significant impact on patients and their families. There is a significant range of therapies available to healthcare professionals for this condition, with many novel or recently studied. There is a need for an update to the joint European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN)/North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) guidelines last released in 2014. We present the prospectively agreed operating procedure and technical review protocol in this manuscript.

METHODS

'Grading of Recommendations Assessment, Development and Evaluation' (GRADE) will be used for all phases of this guideline development. The Guideline Development Group is formed by paediatric gastroenterologists from both the ESPGHAN as well as the NASPGHAN. A prospective exercise will agree on key outcomes, thresholds of magnitude that are significant at small, moderate and large levels. Systematic evidence searches, selection, extraction, appraisal and analysis will be performed following Cochrane guidance and GRADE guidance for objectively agreeing the certainty of findings. Additional use of network meta-analysis will identify areas of broad triangulation in the evidence. Summary of findings tables will be produced and inform evidence to decision frameworks. These will guide GRADE recommendations with voting to reach a consensus.
