Abstract:

Objective To summarize the best evidence of nutrition management in patients with severe pneumonia，aiming to offer evidence-based guidance for clinical healthcare professionals. Methods All evidence on nutrition management in patients with severe pneumonia was retrieved from various databases and websites including BMJ Best Practice，UpToDate，National Guideline Clearinghous（NGC），Guidelines International Network（GIN），Registered Nurses’ Association of Ontario（RNAO），National Institute for Health and Care Excellence（NICE），Cochrane Library，OVID，PubMed，Embase，Web of Science，CINAHL，Chinese Medical Journal Full-text Database，CNKI，VIP，Wanfang，CBM，American Society for Parenteral and Enteral Nutrition（ASPEN），European Society for Clinical Nutrition and Metabolism（ESPEN），Society of Critical Care Medicine（SCCM） and European Society of Intensive Care Medicine（ESICM）. The retrieved evidence included clinical decisions，guidelines，systematic reviews，expert consensuses and evidence summaries. The search period ranged from January 1st，2012 to December 31st，2022. There were 2 researchers who independently assessed the quality of the included studies and then extracted and summarized the evidence by topic. Results A total of 13 articles were involved，including 3 clinical decisions，4 guidelines，1 systematic review，and 5 expert consensuses. A total of 24 pieces of evidence were summarized across 6 aspects which encompassed team building，nutrition screening and assessment，nutritional requirements，nutrition intervention，nutrition monitoring，and health education. Conclusion The production process of this evidence summary followed standardized procedures，ensuring comprehensive content. Medical professionals should integrate clinical conditions，patient factors，and family preferences to select the most optimal evidence in order to enhance patient prognosis and improve medical quality.
