Background

Malnutrition in hospitalized patients with chronic kidney disease (CKD) is a prevalent condition that is related to mortality, higher costs, and prolonged hospital stays, as well as higher hospital readmissions. The relationship between specific nutritional parameters and the days of hospital stay in our population with chronic kidney disease (CKD) has been little explored. We aimed to evaluate the association of days of hospital stay with different nutritional parameters and determine their relationship with hospital readmission.

Methods

Data was analyzed from the database of a retrospective cohort from 2007 to 2021 of patients with CKD who received nutritional care from our service. We included patients >60 years, both sexes, with at least one serum albumin, weight, and height record. Patients with terminal cancer, treatment with some renal replacement therapy, or with missing data were excluded.

Results

419 patients were analyzed; those with longer days of hospital stay (>seven days) decreased serum albumin concentrations, and so did those with CKD stages 3Gb – 5, as well as lower scores in geriatric nutritional risk index (GNRI). Any degree of malnutrition assessed with the subjective global assessment was associated with a greater probability of prolonged stays (Table 1). No significant associations with hospital readmission were observed.

Conclusion

the detection and classification of malnutrition were related to longer days of hospital stay in patients with CKD.
