This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents statistics on ILI-related ED visits from 2016 through 2018. The HCUP State Inpatient Databases (SID) were used to identify ED visits resulting in inpatient admission, and the State Emergency Department Databases (SEDD) were used to identify treat-and-release ED visits from 34 States and the District of Columbia. Three measures characterize ILI-related ED utilization: the population rate of ED visits involving ILI, the percentage of ILI-related ED visits resulting in inpatient admission, and the percentage of total ED visits involving ILI—a measure of the transmissibility and clinical severity of an influenza epidemic. First, monthly trends in ED visits involving ILI are shown. Second, the three metrics are examined across patient and community characteristics. Finally, State variation in the population rate of ILI-related ED visits is shown overall and by age, race/ethnicity, and location of residence. Race/ethnicity statistics are presented for a subset of 27 States with reliable data on race/ethnicity. Because of the large sample size of the SID and SEDD data, small differences can be statistically significant. Thus, only differences greater than or equal to 10 percent are discussed in the text.
本医疗成本与利用项目（HCUP）统计简报展示了2016年至2018年与流感样疾病（ILI）相关的急诊就诊统计数据。HCUP州住院数据库（SID）用于识别导致住院的急诊就诊情况，而州急诊科数据库（SEDD）用于识别来自34个州和哥伦比亚特区的急诊留观就诊情况。有三项指标可描述与ILI相关的急诊利用情况：涉及ILI的急诊就诊人口率、导致住院的ILI相关急诊就诊百分比，以及涉及ILI的急诊就诊总数百分比——这是衡量流感疫情传播性和临床严重程度的一项指标。首先，展示了涉及ILI的急诊就诊的月度趋势。其次，针对患者和社区特征对这三项指标进行了考察。最后，总体上以及按年龄、种族/族裔和居住地点展示了与ILI相关的急诊就诊人口率的州差异。种族/族裔统计数据针对27个拥有可靠种族/族裔数据的州的子集呈现。由于SID和SEDD数据样本量较大，小的差异在统计学上可能具有显著性。因此，文本中仅讨论大于或等于10%的差异。
