Insights
Hospital breastfeeding rates do not fully reflect very-low-birth-weight infant feeding in neonatal intensive care units. Separate reporting may obscure the quality of care for vulnerable infants.
Area of Science:
- Neonatal care
- Public health
- Infant nutrition
Background:
- Breastfeeding is crucial for infant health, especially for premature and low-birth-weight infants.
- Neonatal intensive care units (NICUs) play a vital role in supporting breastfeeding for vulnerable newborns.
- Assessing hospital-wide breastfeeding rates may not accurately represent NICU-specific outcomes.
Purpose of the Study:
- To examine the correlation between overall hospital breastfeeding rates and breastmilk feeding rates for very-low-birth-weight infants in NICUs.
- To evaluate how hospital performance in overall breastfeeding compares to performance in feeding very-low-birth-weight infants.
Main Methods:
- A cross-sectional study analyzed data from 111 California hospitals in 2007-2008.
- Correlation coefficients were calculated between overall and NICU-specific breastfeeding rates.
- Hospitals were categorized into quartiles based on very-low-birth-weight infant feeding rates.
Main Results:
- Correlation varied by NICU level, ranging from 0.13 (intermediate) to 0.48 (regional).
- Only 46% of hospitals with high overall breastfeeding rates were also top performers for very-low-birth-weight infants.
- A notable percentage (11%) of hospitals with low overall rates excelled in feeding very-low-birth-weight infants.
Conclusions:
- Overall hospital breastfeeding rates may not be a sufficient indicator of NICU quality of care.
- Separate reporting of overall and NICU-specific breastfeeding metrics is recommended for a comprehensive quality assessment.
- Understanding disparities in feeding outcomes for vulnerable infants is essential for targeted interventions.
Aim:
To investigate the relationship between breastmilk feeding in very-low-birth-weight infants in the neonatal intensive care unit and breastmilk feeding rates for all newborns by hospital.
Methods:
This was a cross-sectional study of 111 California hospitals in 2007 and 2008. Correlation coefficients were calculated between overall hospital breastfeeding rates and breastmilk feeding rates of very-low-birth-weight infants. Hospitals were categorized in quartiles by crude and adjusted very-low-birth-weight infant rates to compare rankings between measures.
Results:
Correlation between breastmilk feeding rates of very-low-birth-weight infants and overall breastfeeding rates varied by neonatal intensive care unit level of care from 0.13 for intermediate hospitals to 0.48 for regional hospitals. For hospitals categorized in the top quartile according to overall breastfeeding rate, only 46% were in the top quartile for both crude and adjusted very-low-birth-weight infant rates. On the other hand, when considering the lowest quartile for overall breastfeeding hospitals, three of 27 (11%) actually were performing in the top quartile of performance for very-low-birth-weight infant rates.
Conclusions:
Reporting hospital overall breastfeeding rates and neonatal intensive care unit breastmilk provision rates separately may give an incomplete picture of quality of care.
