【摘要】目的 急诊科拥挤现象已成为全球性医疗卫生理由。本项目旨在系统回顾急诊科拥挤现象的研究现况，探讨研究中存在理由和今后研究方向，为解决该理由寻找路径。策略 通过PubMed和BMC开放文献检索系统搜索，对1974年至2012年包含“急诊科”和“拥挤”关键词的论著、综述、评论类1587篇相关文献进行分析。结果 入选1587篇文献中，论著835篇（52.6%），学科建设论文337篇（21.2%），述评（包括述评、评论、视点等）302篇（19.0%），其他（包括综述和系统性回顾）113篇（7.1%）。论著中大部分是单中心观察性研究（n=722，86.5%），仅2.8%为多中心研究。研究文献主要来自美国、加拿大、澳大利亚3个国家（81.0%），但地理分布区域广，多达48个国家和地区报告急诊科拥挤相关论文。且近十年来急诊科拥挤相关研究论文数量急剧增加，2003-2012年间文献占全部文献的79%。从论文主要涉及的内容来看，拥挤度评估策略方面文献最少（5.4%）。结论 本文系统分析了全球急诊科拥挤相关文献构成情况和内涵质量，资料显示急诊科拥挤研究具有地理分布广、论文数量呈急剧增加特点，但论文的质量仍有待提高。急诊科拥挤度评估策略是当前研究的主要瓶颈之

【Abstract】Objective Emergency department overcrowding （EDO） is an increasingly international occurrence which affects the quality and access of health care across the globe. We assessed perceptions of EDO by a detailed and comprehensive surveying of current international research literatures. Methods Through PubMed and BMC electronic literatures search engines from 1974 to 2012， 1587 papers of original articles， reviews and comments with key words “emergency department”AND“crowding”OR “overcrowding” are selected. Results 52.6%（835/1587） all selected literatures is original research articles. 21.2% （n=337） of these papers involved the disciplinary construction of emergency medicine， and editorial comment （included viewpoints） holds almost one fifth （302， 19.0%）. Most common types of study methods in all original researches is single-center cohort study （722/835， 86.5%）， and none of them was multi-center， randomized control clinical trial. The number of papers on EDO is 8 during 1974 and 1988， and gradually elevated to 325 during 1989 and 2002. Yet the number has climbed up to 1254 dramatically （account for 79%） during 2003 and 2012. Together， USA， Canada and Austria， these three countries generated more than three-quarters of all published literatures （81.0%）. So far， the authors in 48 countries and areas ge forth initial contributions in the field of EDO.

The studies and papers about EDO are steadily increasing in recent years. But the investigation shows the research quality still remain need to improve. This systemic review on EDO studies showed that the standardized measurement of EDO has become the bottleneck of EDO study. It is very important and urgent for ED staff to establish an objective and effective EDO evaluation system.

一、建立客观、高效的急诊科拥挤评估策略是今后迫切需要解决的课题。
