Disparities in perinatal quality outcomes for very low birth weight infants in neonatal intensive care.

OBJECTIVE: To determine if hospital-level disparities in very low birth weight (VLBW) infant outcomes are explained by poorer hospital nursing characteristics. DATA SOURCES: Nurse survey and VLBW infant registry data. STUDY
DESIGN: Retrospective study of 8,252 VLBW infants in 98 Vermont Oxford Network hospital neonatal intensive care units (NICUs) nationally. NICUs were classified into three groups based on their percent of infants of black race. Two nurse-sensitive perinatal quality standards were studied: nosocomial infection and breast milk. DATA COLLECTION: Primary nurse survey (N = 5,773, 77 percent response rate). PRINCIPAL
FINDINGS: VLBW infants born in high-black concentration hospitals had higher rates of infection and discharge without breast milk than VLBW infants born in low-black concentration hospitals. Nurse understaffing was higher and practice environments were worse in high-black as compared to low-black hospitals. NICU nursing features accounted for one-third to one-half of the hospital-level health disparities.
CONCLUSIONS: Poorer nursing characteristics contribute to disparities in VLBW infant outcomes in two nurse-sensitive perinatal quality standards. Improvements in nursing have potential to improve the quality of care for seven out of ten black VLBW infants who are born in high-black hospitals in this country. © Health Research and Educational Trust.
