Background Care practices for very preterm infants and the mortality and morbidity of the infants vary widely among countries and regions with different levels of economic development, including the different areas in China. We aimed to compare the obstetric and delivery room practices of two representative tertiary newborn centers in the northwestern and southern regions of China and the mortality and morbidity of their very preterm infants. Methods A retrospective cohort study was conducted. Very preterm infants born between 22(0/7) and 31(6/7) weeks of gestation, and admitted to Qinghai Red Cross Hospital (QHH) and Shenzhen Baoan Women's and Children's Hospital (SZH) from January 1, 2018 to December 31, 2020, were included. The infants' characteristics and short-term outcomes, and the hospitals' care practices were compared between the two cohorts. Results Three hundred and two infants in QHH and 505 infants in SZH were enrolled, and the QHH cohort was more mature than the SZH cohort was (gestational age 30.14 (29.14-31.14) vs. 29.86 (27.86-31.00 weeks, respectively), p < 0.001). Fewer antenatal steroids and more tracheal intubations were used in QHH than in SZH [(73.8% vs. 90.9%, p < 0.001) and (68.2% vs. 35.0%, p < 0.001, respectively)]. The odds of mortality [aOR = 10.31, 95%CI: (6.04, 17.61)], mortality or major morbidity [aOR = 5.95, 95%CI: (4.05, 8.74)], mortality despite active treatment [aOR = 3.14, 95%CI: (1.31, 7.53)], mortality or major morbidity despite active treatment [aOR = 3.35, 95%CI: (2.17, 5.17)], moderate or severe bronchopulmonary dysplasia [aOR = 3.66, 95%CI: (2.20, 6.06)], and severe retinopathy of prematurity [aOR = 3.24, 95%CI: (1.19, 8.83)] were higher in the QHH cohort. No significant difference in the rate of severe neurological injury or necrotizing enterocolitis >= Stage 2 was found between the cohorts. Conclusion Obstetric and delivery room care practices used in the management of very preterm infants differed considerably between the QHH and SZH cohorts. Very preterm infants born in QHH have higher odds of mortality or severe morbidity compared with those born in SZH.
