3家独立急诊部与1家三级医疗急诊部之间的 acuity 水平比较。 （注：“acuity”常见释义为“敏锐；尖锐；剧烈” ，这里在医学语境中可能有特定含义，比如“ acuity level”可能指“ acuity 水平” ，具体准确含义需结合更多上下文确定 ）

INTRODUCTION
Freestanding emergency departments (FEDs) have grown in popularity. They often provide emergent care in areas distant from other EDs. Investigations and research to characterize the operation and dynamics of FEDs are needed. This study characterizes the severity of illness seen at FEDs and compares it with a hospital-based urban tertiary care ED using the emergency severity index (ESI), a quantification of patient acuity.
METHODS
Patient ESI levels were analyzed retrospectively over 1 year for a single hospital system with 1 main urban hospital-based ED and 3 FEDs. Data analysis was completed using analysis of variance with and without time as a factor.
RESULTS
The average ESI level at the main ED (3.04) was lower than the FEDs, respectively (3.42, 3.22, and 3.38) (P < .001). Patient ESI levels were significantly different between FEDs (P < .001).
CONCLUSION
The main ED demonstrated lower ESI levels and thus higher acuity than the 3 affiliated FEDs. There were significantly different acuity levels between the main ED and 3 FEDs as well as between individual FEDs.
引言
独立急诊科（FEDs）越来越受欢迎。它们通常在远离其他急诊科的地区提供急诊护理。需要开展调查和研究来描述FEDs的运作和动态情况。本研究描述了FEDs所见疾病的严重程度，并使用急诊严重程度指数（ESI）（一种对患者急症程度的量化指标）将其与一家城市三级医院急诊科进行比较。
方法
对一个单一医院系统进行了为期1年的回顾性分析，该系统有1个主要的城市医院急诊科和3个FEDs。数据分析采用方差分析，将时间作为一个因素纳入或不纳入分析。
结果
主要急诊科的平均ESI水平（3.04）低于FEDs（分别为3.42、3.22和3.38）（P <.001）。FEDs之间的患者ESI水平存在显著差异（P <.001）。
结论
主要急诊科的ESI水平较低，因此急症程度高于3个附属FEDs。主要急诊科与3个FEDs之间以及各个FEDs之间的急症程度存在显著差异。
