OBJECTIVE
To compare the length of stay (LOS) against the expected date of delivery (EDD) and to describe mortality and LOS outcomes by gestational age (GA) categories over the years.
STUDY DESIGN
Healthcare Cost and Utilization Project Kids' Inpatient database discharge records for years 2003, 2006, 2009, 2012, and 2016 were analyzed. For premature infants after inclusion-exclusion, actual, and calculated LOS were compared. Mortality and LOS outcomes were analyzed by GA and years.
RESULTS
The majority (99%) of infants >28 weeks were discharged by EDD while, for neonate ≤28 weeks, about three-quarters (75%) of infants were discharged by calculated EDD. LOS is increasing while mortality is decreasing by GA categories in recent years.
CONCLUSIONS
This is the largest study of mortality and LOS in the United States. Our study provides evidence-based numbers comparing actual LOS against EDD, which can be used in perinatal settings to counsel parents.
目的
比较实际住院时间（LOS）与预计分娩日期（EDD），并按妊娠年龄（GA）类别描述多年来的死亡率和 LOS 结果。
研究设计
分析了 2003 年、2006 年、2009 年、2012 年和 2016 年医疗保健成本和利用项目儿童住院数据库出院记录。对纳入排除后早产儿的实际 LOS 和计算 LOS 进行了比较。按 GA 和年份分析死亡率和 LOS 结果。
结果
大多数（99%）>28 周的婴儿按 EDD 出院，而对于≤28 周的新生儿，约四分之三（75%）的婴儿按计算的 EDD 出院。近年来，GA 类别中 LOS 呈上升趋势，死亡率呈下降趋势。
结论
这是美国最大的关于死亡率和 LOS 的研究。我们的研究提供了基于证据的实际 LOS 与 EDD 比较数据，可用于围产期环境中为父母提供咨询。
