Impact of nutritional status on the outcome of critically ill pediatric patients.

Abstract

Background: Malnutrition among patients admitted to a pediatric intensive care unit (PICU) is common. However, there is a lack of data on its impact on the critically ill.

Aim: To assess the impact of nutritional status on the outcome of critically ill children admitted to PICU.

Methods: This observational study was conducted in a tertiary care teaching institute for one year, including 210 children aged 1 month to 14 years admitted to a 15-bed PICU for a minimum of 24 hours. Patients with less than 24 hours of PICU stay, who received palliative care, or with syndromic short stature were excluded. Relevant data were collected including anthropometric details, demographic data, duration of mechanical ventilation (MV), PICU, and hospital stay and outcome. Malnourished and well-nourished groups were compared using an independent t-test, one-way analysis of variance, and χ ² test.

Results: Among 210 patients, there were 129 males and 81 females. There were 57 (27.1%) children less than 6 months of age, 95 (45.2%) between 6 months and 5 years, and 58 (27.6%) more than 5 years of age. The prevalence of malnutrition in the study sample was 51.9% (n = 109). The overall mortality was 22.9% (48/210), 26.6% (29/109) among malnourished, and 18.8% (19/101) among well-nourished children (P = 0.241). A significant association was found between the severity of malnutrition and duration of MV (P = 0.001), PICU stay (P = 0.001), and hospital stay (P = 0.021).

Conclusion: Malnutrition is common in critically ill children and contributes to poor clinical outcomes such as duration of MV, PICU, and hospital stay. However, mortality was comparable in both groups.
