OBJECTIVE
To assess the association of NICU occupancy with probability of discharge and length of stay (LOS) among infants born <33 weeks gestational age (GA).
STUDY DESIGN
Retrospective study of 3388 infants born 23-32 weeks GA, admitted to five Level 3/4 NICUs (2014-2018) and discharged alive. Standardized ratios of observed-to-expected number of discharges were calculated for each quintile of unit occupancy. Multivariable linear regression models were used to assess the association between occupancy and LOS.
RESULTS
At the lowest unit occupancy quintiles (Q1 and Q2), infants were 12% and 11% less likely to be discharged compared to the expected number. At the highest unit occupancy quintile (Q5), infants were 20% more likely to be discharged. Highest occupancy (Q5) was also associated with a 4.7-day (95% CI 1.7, 7.7) reduction in LOS compared Q1.
CONCLUSION
NICU occupancy was associated with likelihood of discharge and LOS among infants born <33 weeks GA.
目的
评估胎龄小于33周（GA）的婴儿入住新生儿重症监护病房（NICU）与出院概率及住院时间（LOS）之间的关联。
研究设计
对2014年至2018年期间入住5家三级/四级NICU且存活出院的3388例胎龄23 - 32周的婴儿进行回顾性研究。计算每个病房占用率五分位数的观察出院数与预期出院数的标准化比率。采用多变量线性回归模型评估占用率与住院时间之间的关联。
结果
在最低的病房占用率五分位数（Q1和Q2）时，婴儿出院的可能性比预期出院数分别低12%和11%。在最高的病房占用率五分位数（Q5）时，婴儿出院的可能性高20%。与Q1相比，最高占用率（Q5）还与住院时间缩短4.7天（95%可信区间1.7, 7.7）相关。
结论
胎龄小于33周的婴儿入住NICU与出院可能性及住院时间有关。
