Abstract：
OBJECTIVE: To describe the change in admission rate and demographic profile of patients admitted to ICUs throughout Denmark before and during first wave of the SARS-CoV-2 pandemic.
METHODS: A register-based national observational study of all patients admitted to ICU from December 2019 until April 2020, comparing ICU admission before and after lockdown.
RESULTS: The number of admissions declined, especially in the age groups below 18 and above 70. The sex distribution and the comorbidity-level remained unchanged. The length of hospital stay prior to ICU admission increased. Overall fewer patients were admitted electively.
CONCLUSIONS: Fewer patients were admitted to ICU and waited longer for admission during the first wave of the COVID-19 pandemic.

摘要：
目的：描述在SARS-CoV-2大流行的第一波之前和期间，整个丹麦的ICU患者的入院率和人口统计学特征的变化。
方法：一项针对2019年12月至2020年4月入住ICU的所有患者的基于注册的全国性观察性研究，比较了封锁前后入住ICU的情况。
结果：入院人数下降，特别是在18岁以下和70岁以上的年龄组。性别分布和合并症水平保持不变。入住ICU前的住院时间增加。总体而言，选择性入院的患者较少。
结论：在第一波COVID-19大流行期间，进入ICU的患者较少，等待入院的时间更长。
