“…The patient populations were divided as four groups: no risk, low risk, high risk and very high risk groups. There were a few studies explaining the relevance between this risk evaluation and outcomes of patients based on this classification as mentioned above, but there was no notable result reporting a relevance between risk assessment and actual incidence of RS [20]. In this study, "ASPEN consensus recommendations for refeeding syndrome", which specified criteria to identify the patients at risk for RS in advance was used as a risk evaluation.…”

The aim of this study is to demonstrate clinical characteristics of refeeding syndrome (RS) and clinical utility of several guidelines including American Society for Parenteral and Enteral Nutrition consensus recommendations for RS and National Institute for Clinical Excellence guidelines. Materials and Methods: Eighty-six patients screened for RS based on two guidelines were enrolled in this study. We evaluated the severity of RS after the initiation of 'dextrose infusion' and 'balanced nutrition support' with calculation of 5-day electrolyte changes. The primary outcome was 6-month mortality and secondary outcomes were duration of intensive care unit stay in days, duration of mechanical ventilation in days, and ventilator-free days at the 28th day. Results: We observed statistically different distributions in terms of prevalence of RS on the basis of two different start times of caloric support (P=0.021). There was no statistically significant relationship between the risk of RS and severity of RS based on both guidelines. Also, the relevance between severity of RS and outcomes was not significant in our study. In multivariable logistic regression analysis of factors associated with outcomes, the significant factor for primary outcome was the 'patients with significant risk' (odds ratio, 9.65; 95% confidence interval, 1.83~50.90; P=0.007). Conclusion:We demonstrated that even initial administration of dextrose solution and propofol could cause severe RS in critically ill patients. In addition, significant risk of RS was a predictive factor for 6-month mortality. Thus, it is essential to monitor the occurrence of RS even during initial resuscitation in patients with unstable metabolism.

“…24 Yoshida et al used the NICE guidelines to operationalize RFS risk classification and found an association between RFS and death. 25 Future research can test other guidelines to classify RFS. 26 On the other hand, a prospective cohort study in the United Kingdom mirrored the NICE criteria, focusing on unintentional weight loss and energy deficit, but found no association between RFS and death among ICU patients.…”

“…Another definition for RFS was based on the criteria provided by Britain's National Institute for Health and Care Excellence (NICE), which operationalizes RFS based on at least one of the following conditions: BMI <16 kg/m 2 , a recent unintentional weight loss >15%, minimal nutrition intake for >10 days, and/or low plasma concentrations of potassium, phosphate or magnesium before feeding; and those with at least two of the following conditions: BMI <18.5 kg/m 2 , a recent weight loss >10%, very little nutrition intake for >5 days, and/or a history of alcohol abuse or drug use, including insulin, chemotherapy or diuretics 24 . Yoshida et al used the NICE guidelines to operationalize RFS risk classification and found an association between RFS and death 25 . Future research can test other guidelines to classify RFS 26 .…”

BackgroundPatients in the intensive care unit (ICU) are at high risk for refeeding syndrome (RFS), yet there is uncertainty regarding how RFS should be operationalized in the ICU. We evaluated different definitions for RFS and tested how they associated with patient‐centered outcomes in the ICU.MethodsThis was a retrospective comparison study. Patients age ≥18 years were eligible if they were newly initiated on enteral feeding while hospitalized in the ICU. Eight definitions for RFS were operationalized, including that from the American Society for Parenteral and Enteral Nutrition (ASPEN), all based on electrolyte levels from immediately before until up to 5 days after the initiation of enteral nutrition. Patients were followed for death or for ICU‐free days, a measure of healthcare utilization.ResultsIn all, 2123 patients were identified, including 406 (19.1%) who died within 30 days of ICU admission and 1717 (80.9%) who did not. Prevalence of RFS varied from 1.5% to 88% (ASPEN definition) depending on the RFS definition used. The excess risk for death associated with RFS varied from 33% to 92% across definitions. The development of RFS based on the ASPEN definition was associated with a greater decrease in ICU‐free days compared with other definitions, but the relationship was not statistically significant.ConclusionEight definitions for RFS were evaluated, none of which showed strong associations with death or ICU‐free days. It may be challenging to achieve a standardized definition for RFS that is based on electrolyte values and predicts mortality or ICU‐free days.

“…Then, the cell membrane Na + -K + -ATPase starts actively, pumping sodium out of the cell and taking potassium into the cell. As a result, the uptake of serum phosphorus and magnesium further increased [32]. In view of the above two effects, early nutritional support is bene cial for regulating the body homeostasis to better tolerate changes in the internal environment in the process of nutrition input, and reduce the RS incidence.…”

Background & aims: Nutrition therapy is an inevitable supportive intervention for COVID-19 patients with high nutritional risks. However, the suitable initiation time of nutrition still remains to be explored. The aim of this study is to determine the association between the enteral nutrition initiation and the incidence of refeeding syndrome for severe COVID-19 patients with high nutritional risks. Method: We compared the different initiation times and observed their relationship with the incidence of Refeeding Syndrome (RS). We retrospectively collected data of 124 confirmed severe COVID-19 cases with ≥ 3 scores of Nutrition Risk Screen - 2002 who received Enteral Nutrition (EN) from January 1st to April 30th of 2020 in Tongji Hospital. Based on the initiation time, patients who received EN within two days after admission were classified into the early enteral nutrition (EEN) group, while the others were included in the late enteral nutrition (LEN) group. The serum levels of potassium, phosphorus, and magnesium were measured on the third day after EN to compare the incidence of RS between the two groups. Results: Fifty-four (43.55%) patients were included in the EEN group, while 70 (56.45%) belonged to the LEN group. The mean time interval of EN was one day in EEN and seven days in LEN. The majority of laboratory markers were comparable between the two groups on admission. Three days after EN support, the levels of serum potassium, sodium, phosphorus, and magnesium were significantly lower, and the incidence, as well as the degree of RS, was significantly higher in the LEN group. Conclusion: We conclude that early EN could be a reasonable mode to reduce the incidence of RS in severe COVID-19 patients with high nutritional risks.
