Improved Outcomes of Very Low Birth Weight Infants in Korea: 2015-2016 vs. 2021-2022 From the Korean Neonatal Network.

ABSTRACT:

Background

This study aimed to analyze improvements in the survival rates and morbidities of very low birth weight infants (VLBWIs) in the Republic of Korea from 2015 to 2022.

Methods

Data from the Korean Neonatal Network were used to assess survival and morbidity trends among VLBWIs, particularly focusing on changes across different gestational ages. The analysis included a comparison with data from other neonatal networks, such as the Australian and New Zealand Neonatal Network, Canadian Neonatal Network, Swedish Neonatal Quality Register, Neonatal Research Network Database Japan, and United States National Vital Statistics Reports, to understand differences in survival and morbidity outcomes.

Results

The survival rate of VLBWIs in Korea rose from 86% in 2015-2016 t
