This Healthcare Cost and Utilization Project (HCUP) Statistical Brief presents statistics on the cost of ED visits in the United States using the 2017 Nationwide Emergency Department Sample (NEDS). Total ED charges were converted to costs using HCUP Cost-to-Charge Ratios based on hospital accounting reports from the Centers for Medicare & Medicaid Services (CMS). ED visits include patients treated and released from the ED, as well as those admitted to the same hospital through the ED. Aggregate costs, average costs, and number of ED visits are presented by patient and hospital characteristics. Because of the large sample size of the NEDS data, small differences can be statistically significant. Thus, only percentage differences greater than or equal to 10 percent are discussed in the text.
本医疗成本与利用项目（HCUP）统计简报呈现了使用2017年全国急诊科样本（NEDS）得出的美国急诊科就诊成本统计数据。根据医疗保险与医疗补助服务中心（CMS）的医院会计报告，利用HCUP成本收费比率将急诊总费用转换为成本。急诊科就诊包括在急诊科接受治疗并出院的患者，以及通过急诊科入院至同一家医院的患者。按患者和医院特征列出了总成本、平均成本以及急诊科就诊次数。由于NEDS数据样本量较大，微小差异在统计上可能具有显著性。因此，文本中仅讨论百分比差异大于或等于10%的情况。
