BACKGROUND
Differences in neonatal intensive care unit (NICU) quality of care provided to very-low-birth-weight (VLBW; <1500g) infants may contribute to the persistence of racial/ethnic disparity. An examination of such disparities in a population-based sample across multiple dimensions of care and outcomes is lacking.
METHODS
Prospective observational analysis of 18,616 VLBW infants in 134 California NICUs between January 1, 2010 to December 31, 2014. We assessed quality of care delivery via the Baby-MONITOR, a composite indicator consisting of nine process and outcome measures of quality. For each NICU we calculated a risk adjusted composite and individual component quality score for each race/ethnicity. We standardized each score to the overall population to compare quality of care between and within NICUs.
RESULTS
We found clinically and statistically significant racial/ethnic variation in quality of care delivery between NICUs as well as within NICUs. Composite quality scores ranged by 5.26 standard units (range −2.30 to 2.96). Adjustment of Baby-MONITOR scores by race/ethnicity had only minimal effect on comparative assessments of NICU performance. Among subcomponents of the Baby-MONITOR, non-Hispanic White infants scored higher on measures of process compared with non-Hispanic Blacks and Hispanics. Compared with Whites, non-Hispanic Blacks scored higher on measures of outcome; Hispanics scored lower on seven of the nine Baby-MONITOR subcomponents.
CONCLUSION
Significant racial/ethnic variation in quality of care delivery exists between and within NICUs. Providing feedback of disparity scores to NICUs could serve as an important starting point for promoting improvement and reducing disparities.
