Emergency Department (ED) Length of stay (LOS) has been associated with poor patient outcomes, which has led to the implementation of time targets designed to keep EDLOS below a specific limit. The cut-offs defining long EDLOS varies across settings and seem to be arbitrarily chosen. This study aimed to clarify the meaning of long EDLOS.
A concept analysis using the Walker and Avant approach was conducted. It included a literature search aiming to identify all uses of the concept, resulting in a set of defining attributes and a way of measuring the concept empirically.
Long EDLOS was primarily used as proxy for other phenomena, e.g. boarding or crowding. The definitions had cut-offs ranging between 4 and 48 h. The attributes defining long EDLOS was waiting, a crowded ED environment and an inefficient organization.
Time targets are probably more suitable when directed towards and tailored for specific sub-groups of the ED population.
急诊部（ED）停留时间（LOS）与不良患者结局相关，这导致实施了旨在将 ED LOS 保持在特定限制以下的时间目标。定义长 ED LOS 的截止值因设置而异，似乎是任意选择的。本研究旨在阐明长 ED LOS 的含义。
使用 Walker 和 Avant 方法进行概念分析。它包括一项旨在确定该概念所有用途的文献检索，从而确定了一组定义属性，并以一种经验性的方式测量该概念。
长 ED LOS 主要用作其他现象的代理，例如登机或拥挤。定义的截止值在 4 至 48 小时之间。定义长 ED LOS 的属性是等待、拥挤的 ED 环境和低效的组织。
时间目标可能更适合针对 ED 人群的特定亚组进行定向和定制。
