Abstract
BACKGROUND: Nutrition support is often delayed or interrupted. The aim of this study is to identify reasons for and quantify time spent without nutrition in a mixed medical-surgical-cardiac pediatric intensive care unit (PICU). METHODS: Data were prospectively collected to describe the patient cohort (anthropometrics and diagnostic category) and nutrition practices (time to nutrition initiation; frequency, duration, and causes of interruptions; and overall caloric intake). Descriptive statistics were used; comparisons of groups were performed using an independent t test and P < .05 as significance. RESULTS: The mean (standard deviation) time to nutrition initiation was 22.8 (16.6) hours following admission; 35% of patients were initiated after >24 hours. Nutrition was interrupted 1.2 (2.0) times per patient. Time spent without nutrition due to interruptions was 11.6 (23.0) hours, up to 102 hours. Patients spent 42.4% (28.2%) of their median (range) PICU admission of 2.9 days (0.25-39 days) without any form of nutrition. Patients aged 0-6 months had a significantly higher mean number and duration of interruptions (P = .001 and P < .001, respectively) compared with children >6 months. Interruptions due to surgery and planned extubation lasted significantly longer than all other interruptions (P < .001 and P = .001, respectively). Pediatric Risk of Mortality (PRISM) III scores were not correlated with percentage of length of stay spent without nutrition (r = 0.137). CONCLUSIONS: Prolonged time to nutrition initiation and interruptions in delivery caused pediatric patients to spend a high proportion of admission without nutrition support, preventing most from meeting energy requirements. Further research addressing specific patient outcomes is required to define optimal initiation times and appropriate procedural-specific fasting times.
