Insights
A standardized nutrition pathway improved weight gain in infants with congenital heart disease (CHD). This approach reduced weight loss during hospital stays for infants undergoing neonatal cardiac surgery.
Area of Science:
- Pediatric Cardiology
- Clinical Nutrition
- Health Services Research
Background:
- Infants with congenital heart disease (CHD) often experience growth challenges.
- Effective nutritional management is crucial for improving outcomes in these vulnerable infants.
- Standardized clinical pathways can optimize care delivery and patient results.
Purpose of the Study:
- To assess the impact of a standardized feeding approach on weight-for-age Z score (WAZ) changes in infants with CHD during their hospital stay.
- To evaluate the effectiveness of a clinical nutrition pathway in improving nutritional outcomes for infants undergoing neonatal cardiac surgery.
Main Methods:
- A retrospective cohort study analyzed 987 infants undergoing neonatal cardiac surgery between 2009 and 2018.
- Weight-for-age Z score (WAZ) changes over hospital length of stay (HLOS) were compared before and after the implementation of a standardized feeding pathway in 2013.
- Linear mixed-effects models were used to estimate WAZ change, adjusting for patient characteristics.
Main Results:
- The standardized feeding approach was associated with a significantly higher WAZ change over HLOS (β = 0.16, P < .001), indicating reduced WAZ loss.
- Infants with single ventricle CHD showed a greater improvement in WAZ change compared to those with 2 ventricle CHD.
- The pathway demonstrated effectiveness for both single and two-ventricle CHD categories.
Conclusions:
- A structured nutrition therapy approach using a standardized pathway significantly improves weight change outcomes in infants with CHD before hospital discharge.
- This standardized pathway is beneficial for infants with both single and 2 ventricle CHD requiring neonatal cardiac surgery.
- Implementing organized nutrition interventions can positively impact growth trajectories in critically ill infants.
Objective:
To evaluate the effect of a standardized feeding approach using a clinical nutrition pathway on weight-for-age Z score (WAZ) over hospital length of stay (HLOS) for infants with congenital heart disease (CHD).
Study Design:
A 10-year retrospective cohort study examined eligible infants who underwent neonatal cardiac surgery between July 2009 and December 2018 (n = 987). Eligibility criteria included infants born at least 37 weeks of gestation and a minimum birth weight of 2 kg who underwent cardiac surgery for CHD within the first 30 days of life. Using the best linear unbiased predictions from a linear mixed effects model, WAZ change over HLOS was estimated before and after January 2013, when the standardized feeding approach was initiated. The best linear unbiased predictions model included adjustment for patient characteristics including sex, race, HLOS, and class of cardiac defect.
Results:
The change in WAZ over HLOS was significantly higher from 2013 to 2018 than from 2009 to 2012 (β = 0.16; SE = 0.02; P < .001), after controlling for sex, race, HLOS, and CHD category, indicating that infants experienced a decreased WAZ loss over HLOS after the standardized feeding approach was initiated. Additionally, differences were found in WAZ loss over HLOS between infants with single ventricle CHD (β = 0.26; SE = 0.04; P < .001) and 2 ventricle CHD (β = 0.04; SE = 0.02; P = .04).
Conclusions:
These data suggest that an organized, focused approach for nutrition therapy using a standardized pathway improves weight change outcomes before hospital discharge for infants with single and 2 ventricle CHD who require neonatal cardiac surgery.
