ABSTRACT

Background:

Patients with COVID-19 experience prolonged ICU stays. The rate of malnutrition in hospitalized patients remains controversial as well as the appropriate nutrition therapy for these patients. The purpose of the study was to evaluate the impact of nutrition support on clinical outcomes in critically ill patients with COVID-19. Method(s) This was a retrospective chart review involving 48 adults, critically ill patients admitted with confirmed SARS-CoV-2 infection. Data extracted included demographic, anthropometric, medical history, biochemical tests, medications, nutrition support protocol, clinical outcomes, length of stay, and ventilator status. We tested associations between aspects of nutrition support (such as early versus delayed feeding, adequacy, and patient positioning) and clinical outcomes (ICU length of stay, weight status, malnutrition status, refeeding syndrome, and ventilator days) using Chi-square, and t-tests, with significance established at the level of p <= 0.05. Result(s) Thirty-eight percent (18) of the patients met the criteria for malnutrition using the Global Leadership Initiative on Malnutrition (GLIM) tool. Approximately 83% of these patients did not have a documented diagnosis of malnutrition in the electronic medical record. More than half of the patients in the study (58.3%) were placed in prone position as part of their treatment and only 7% of these had documented signs of feeding intolerance. None of the patients were switched to total parenteral nutrition (TPN). Only 37% of the patients received adequate protein within the first week of nutrition support while 98% had adequate or exceeded caloric needs. There was no difference in percent weight loss among patients who received inadequate protein compared to those who had adequate protein. Inadequate protein intake was associated with shorter ICU stays (p = 0.04) and fewer ventilator days (p = 0.01) compared to those with adequate protein. Patients who received inadequate or exceeded their calories needs also had shorter ICU stays and fewer ventilator days (p > 0.05). In the context of this study, shorter ICU stays translated into fewer days of life, as 98% of the studied population died before ICU discharge. There were no associations between early nutrition support and selected biochemical parameters. Conclusion(s) The rate of malnutrition was remarkable and largely undocumented. Most patients did not meet the minimum estimated protein needs. Studies with larger sample sizes are needed to examine appropriate protein needs and the effect of nutrition support in patients with COVID-19. Diagnosing and documenting malnutrition warrants heightened attention.
