To investigate the impact of the introduction of Integrated Maternal-Fetal Intensive Care Unit (MFICU) reimbursement rates for high-risk newborns in South Korea.
The present study used data from the Population Dynamics data released annually by Statistics Korea, which contain information on all births in the country from October 1, 2015, to September 31, 2019. The MFICU reimbursement fee began on October 1, 2017, and the follow-up period was 24 months before and after the intervention. The dependent variable was defined as either premature births (before 37 weeks of pregnancy) or underweight births (birth weight ≤2.5 kg). A total of 1 377 841 infants were included in the present study, and an Interrupted Time Series with segmented regression analysis was performed.
After the intervention, the premature or low-birth-weight deliveries decreased by approximately 0.4%. The difference in the level change was more significant in legitimate children and multiple births. Premature neonates showed a significantly different level of change compared with low-birth-weight neonates.
The expansion of the MFICU reduces high-risk births, such as premature births and those involving low birth weight. To effectively care for high-risk deliveries, the enhancement of obstetric care and continuous medical support policies must be maintained.
探讨韩国引入综合母婴重症监护病房（MFICU）对高危新生儿报销率的影响。
本研究使用了韩国统计局每年发布的人口动态数据，其中包含2015年10月1日至2019年9月31日该国所有出生情况的信息。MFICU报销费用于2017年10月1日开始，随访期为干预前后各24个月。因变量定义为早产（妊娠37周前）或低体重出生（出生体重≤2.5千克）。本研究共纳入1377841名婴儿，并进行了分段回归分析的中断时间序列分析。
干预后，早产或低体重分娩减少了约0.4%。合法出生婴儿和多胞胎在水平变化上的差异更为显著。早产新生儿与低体重新生儿相比，水平变化存在显著差异。
MFICU的扩展减少了早产和低体重等高危分娩情况。为有效护理高危分娩，必须维持强化产科护理和持续医疗支持政策。
