Introduction: In the spring of 2017, the American Society for Parenteral and Enteral Nutrition (ASPEN) Parenteral Nutrition Safety Committee and the Clinical Practice Committee convened an interprofessional task force to develop consensus recommendations for identifying patients with or at risk for refeeding syndrome (RS) and for avoiding and managing the condition. This report provides narrative review and consensus recommendations in hospitalized adult and pediatric populations.

Methods: Because of the variation in definitions and methods reported in the literature, a consensus process was developed. Subgroups of authors investigated specific issues through literature review. Summaries were presented to the entire group for discussion via email and teleconferences. Each section was then compiled into a master document, several revisions of which were reviewed by the committee.

Findings/recommendations: This group proposes a new clinical definition, and criteria for stratifying risk with treatment and screening strategies. The authors propose that RS diagnostic criteria be stratified as follows: a decrease in any 1, 2, or 3 of serum phosphorus, potassium, and/or magnesium levels by 10%-20% (mild), 20%-30% (moderate), or >30% and/or organ dysfunction resulting from a decrease in any of these and/or due to thiamin deficiency (severe), occurring within 5 days of reintroduction of calories.

Conclusions: These consensus recommendations are intended to provide guidance regarding recognizing risk and identifying, stratifying, avoiding and managing RS. This consensus definition is additionally intended to be used as a basis for further research into the incidence, consequences, pathophysiology, avoidance, and treatment of RS.

Reference work for leading, current and selected literature in the field of clinical nutrition

Publications on clinical nutrition have grown steadily in recent years and the scientific evidence has been improved by numerous observational as well as intervention studies. Various umbrella organisations, such as the Swiss Society for Clinical Nutrition (GESKES), the German Society for Nutritional Medicine (DGEM) or the European Society for Clinical Nutrition and Metabolism (ESPEN) publish guidelines on nutrition in various clinical situations at regular intervals. Thus, a large amount of literature is available for evidence-based nutritional medicine.

The NutriBib aims to filter out authoritative publications in the various fields of nutritional medicine and thus to provide an overview of the abundance of literature. A large number of experienced nutrition experts contributed to the selection of relevant sources and allow a broadly based selection. Nevertheless, the literature selection cannot be considered exhaustive. Specific literature can be found by entering search words (using the magnifying glass at the top right) or by searching the table of contents.
