Síndrome de realimentação em pacientes adultos: estudo retrospectivo em um hospital universitário

Abstract

To evaluate the prevalence of adult and elderly individuals with risk criteria for Refeeding Syndrome (RS), the relationship between the listed groups and the main outcomes, in patients admitted from January to July 2022 in a University Hospital. Method: Retrospective, cross-sectional study, through analysis of electronic medical records of adult and elderly hospitalized patients. Three groups were analyzed: moderate risk of RS (food intake less than 50% and without reaching the nutritional target and/or BMI between 16 and 18.5kg/m²); serious risk: Food intake of less than 50% (BMI <16kg/m²) and RS. Results: 121 patients were evaluated, of which 38.84% presented RS. Of these, 49.58% were in the moderate risk group and 11.57% in the severe risk group. Regarding age, 61.98% were elderly and 38.02% were adults. Conclusion: There were significant differences in prevalence between adults and the elderly (x2 (1) = 6.95, p < 0.05), being higher in the elderly. The prevalence of RS was higher in elderly people (60 to 74 years old), in relation to groups of elderly people over 74 years old, and was statistically significant. Changing antibiotics during hospitalization was more prevalent in the moderate risk group for RS. Patients at risk of refeeding syndrome or IRS did not show a significant association with death.
