Background Severe burns are associated with a plethora of profound metabolic, immunologic, and physiologic responses, demanding prompt and adequate management. The objective of the present study was to review, compare, and critically appraise medical nutrition therapy guidelines for adult patients with severe burns, and produce salient points for the future update of relevant guidelines. Methods A total of 8 clinical practice guidelines developed by the American Burn Association (ABA), the European Burn Association (EBA), the European Society for Parenteral and Enteral Nutrition (ESPEN), the Midlands National Health Service, the Society for Critical Care Medicine (SCCM)/American Society for Parenteral and Enteral Nutrition (ASPEN), the Spanish Society of Intensive Care Medicine and Coronary Units and Spanish Society of Parenteral and Enteral Nutrition, the Indian Association for Parenteral and Enteral Nutrition (IAPEN), and the International Society for Burn Injury regarding medical nutrition therapy in burn patients was independently reviewed by a team of 4 multidisciplinary researchers using the Appraisal of Guidelines for Research & Evaluation (AGREE II) instrument. Results From the appraised guidelines, the SCCM/ASPEN guidelines received the greatest scoring in the majority of AGREE domains compared with ABA, EBA, and IAPEN, which obtained the lowest scores. On the other hand, the ESPEN guidelines provided the majority of information concerning nutrition support and medical nutrition therapy. Conclusion Our study identified gaps in most nutrition guidelines and emphasized methodologic issues that could improve the quality of future guidelines concerning nutrition support among adult severe burn patients.

Objective: Despite the fact that pediatric pancreatitis is an uncommon disease, its prevalence has increased in recent years. Nevertheless, until 4 years ago, the lack of nutritional guidelines for pediatric pancreatitis was evident, with all recommendations being based on clinical practice guidelines (CPGs) for adults. The aim of the present study was to review and critically appraise guidelines for the medical nutrition therapy (MNT) of pediatric pancreatitis. Methods: A comprehensive search was performed in electronic databases (PubMed, Scopus, National Institute for Health and Care Excellence), the International Guidelines Network, BMJ best practice, and the Scottish Intercollegiate Guidelines Network to identify CPGs on the MNT of pediatric pancreatitis. The validated AGREE II tool was used for guidelines appraisal by a team of 3 independent multidisciplinary reviewers. Results: A total of 4 CPGs were retrieved with pediatric pancreatitis MNT information. Out of the 4 advising bodies in total, the joint society paper published by the ESPGHAN/NASPGHAN received the highest score in almost all domains, whereas the Belgian consensus obtained the lowest score in all domains but stakeholder involvement, and was not recommended by 2 out of 3 reviewers. Conclusions: Pediatric pancreatitis guidelines appear heterogenous in quality, rigour, and transparency. Our study points out existing gaps and biases in the CPGs, and delineates the need for improving the domains identified as being of low-quality.
