Impact of protein intake and nutritional status on the clinical outcome of critically ill patients

Abstract

Objective To evaluate the association of nutritional status and protein intake with the clinical outcomes of critically ill patients receiving enteral nutrition therapy in an intensive care unit. Methods A retrospective observational analytical study was performed by collecting secondary data recorded in medical records of patients ≥ 18 years of age who were admitted to the intensive care unit and who received exclusive enteral nutrition therapy for at least 72 hours in 2017. Nutritional status was assessed by body mass index and arm circumference. For the estimation of protein requirements, the recommendation of the American Society for Parenteral and Enteral Nutrition was considered. Nutritional adequacy was assessed by the daily collection of prescribed and administered enteral formula. In the analyses, parametric and nonparametric tests were used, and significance was set at p <0.05. Results Of the 188 patients evaluated, 71.3% were male. The median age of the patients was 48.5 years (31.0 - 63.75). The main clinical diagnosis was trauma (46.3%), and eutrophic was the most frequent nutritional status (54.8% according to body mass index and 46.4% according to arm circumference). Protein adequacy was not attained in 56.4% of patients, and only 46.8% reached the minimum protein recommendation. The occurrence of mortality was associated with nutritional diagnosis, body mass index (p = 0.023), arm circumference (p = 0.041) and protein adequacy (p = 0.012). Conclusion Nutritional status and protein intake were significantly associated with the clinical outcomes of critically ill patients.

Prognostic nutritional index to predicting mortality in surgical intensive care patients

“…Malnutrition, which is associated with poor outcomes up to mortality, progresses silently, especially in ICU cases, and is difficult to recognize when not suspected. Evaluation of nutritional status in critically ill patients in admission to the ICU; It has been reported that it can help prevent bad outcomes by enabling the early detection of risky cases and providing more effective nutritional support [26]. Using a scoring system that is easy to implement and will not cause loss of time, labor, and cost can easily diagnose this patient group and provide a chance for early intervention in ICUs where critical cases are followed.…”

“…It is known that immuno-nutritional status has an effect on clinical outcomes in intensive care (ICU) patients [1]. Malnutrition may occur in critical patient groups due to various reasons.…”

Optimal Nutritional Factors Influencing the Duration of Mechanical Ventilation Among Adult Patients with Critical Illnesses in an Intensive Care Unit

“…It can improve their respiratory function, structure, increase weaning ability 10 and reduce mechanical ventilator duration. 11 It has been discovered that nutrition importantly supports critical patient recovery by affecting treatment outcome and mechanical ventilator duration. 12 Factors correlated with nutritional conditions for critical patients using ventilator have been studied, however, it is not applied.…”

“…[1][2][3][4][5][6] The selected factors include malnutrition, age, disease severity, dyspnea scale, initial EN time, and targeted calorie requirement. 6,[10][11][12][13] It could be defined as a guideline in mechanical ventilation for critical patients 13 leading to ventilator availability and reduced admission duration. Therefore, the purpose of the current study was to examine nutritional factors and predict the effect that those variables have on the duration of mechanical ventilation among patients with a critical illness.…”
