Abstract:
Objective:To evaluate and summarize the best evidence of energy and protein intake targets and calculation in adult critically ill patients, and to provide evidence-based basis for critical nutrition management.Methods:Evidence related to energy and protein intake targets and calculation of adult critically ill patients, including guideline, expert consensus, systematic review and evidence summary, were systematically searched in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Cochrane Library, UpToDate, BMJ Best Practice, Joanna Briggs Institute (JBI), Web of Science, SinoMed, Medive, China National Knowledge Infrastructure, Wanfang database, VIP database, Guidelines International Network (GIN), National Institute for Health and Care Excellence (NICE), National Guideline Clearinghouse (NGC), Registered Nurses Association of Ontario (RNAO), and Society of Critical Care Medicine (SCCM) from January 2012 to June 2022. Two researchers independently evaluated the quality of the included literatures using the JBI Evidence-based Health Care Center evaluation tool and the Appraisal of Clinical Practice Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), extracted and summarized the best evidence for the nutritional intake goal and calculation of adult critically ill patients, and described the evidence.Results:A total of 18 literatures were included, including 5 clinical guidelines, 8 expert consensus, 3 systematic reviews and 2 evidence summaries. After literature quality evaluation, 18 articles were all enrolled. The evidence was summarized from the four aspects, including energy target calculation method, dose body weight, energy and protein intake target, and calculation method, 24 pieces of the best evidence were finally formed.Conclusions:The best evidence of energy and protein intake targets and calculation for critically ill patients was summarized based on evidence-based. Clinical medical staff can choose indirect calorimetry to calculate energy goals when equipment is available. Patient's height, body weight should be recorded accurately, dose body weight can be determined by body mass index (BMI). Meanwhile, blood urea nitrogen (BUN) loss, fat-free body weight, simple formulas and other methods should be used to continuously evaluate and adjust protein intake targets, to achieve the purpose of optimizing intensive nutrition support.
