Malnutrition and Nutrition Support in Latin American PICUs: The Nutrition in PICU (NutriPIC) Study

Abstract

OBJECTIVES: To characterize the nutritional status of children admitted to Latin American (LA) PICUs and to describe the adequacy of nutrition support in reference to contemporary international recommendations. DESIGN: The Nutrition in PICU (NutriPIC) study was a combined point-prevalence study of malnutrition carried out on 1 day in 2021 (Monday 8 November) and a retrospective cohort study of adequacy of nutritional support in the week preceding. SETTING: Four-one PICUs in 13 LA countries. PATIENTS: Patients already admitted to the PICU of 1 month to 18 years old on the study day were included in the point-prevalence study. For the retrospective arm, we included patients receiving nutritional support on the study day and with a PICU length of stay (LOS) greater than or equal to 72 hours. Exclusion criteria were being a neonate, conditions that precluded accurate anthropometric measurements, and PICU LOS greater than 14 days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 316 patients screened, 5 did not meet age criteria. There were 191 of 311 patients who were included in the point-prevalence study and underwent anthropometric evaluation. Underweight and length for age less than –2 z scores were present in 42 of 88 children (47.7%) and 41 of 88 children (46.6%) less than 24 months old, and 14 of 103 (13.6%) and (23/103) 22.3% of 103 children greater than or equal to 24 months, respectively. Evidence of obesity (body mass index > 2 z score) was present in 7 of 88 children (5.7%) less than 24 months old and 13 of 103 children (12.6%) greater than or equal to 24 months. In the 115 of 311 patients meeting criteria for the retrospective arm, a total of 98 patients reported complete nutritional data. The 7-day median (interquartile range) adequacy for delivered versus recommended enteral energy and protein requirement was 114% (75, 154) and 99% (60, 133), respectively. CONCLUSIONS: The NutriPIC study found that in 2021 malnutrition was highly prevalent especially in PICU admissions of less than 24 months old. Retrospectively, the 7-day median nutritional support appears to meet both energy and protein requirements.
