A single-site study described differences between homeless and non-homeless patient utilization of the emergency department (ED). No prior study has examined ED use by the homeless on a national level.
To analyze national ED utilization by homeless patients.
Data were extracted from the 2005 National Hospital Ambulatory Medical Care Survey. SAS callable SUDAAN was used to produce national estimates. Results. Of the 115 million visits to national EDs in 2005, 472,922 were made by homeless patients. In comparison with the non-homeless, these patients were more likely to arrive by ambulance and to be uninsured. Both groups had similar admission rates and triage urgency, with a trend toward increased diagnostic testing for homeless patients.
Homeless patients who visited EDs in 2005 were more likely to arrive by ambulance despite similar triage urgency and admission rates compared with the non-homeless, and were less likely to be insured.
一项单中心研究描述了无家可归者与非无家可归者在急诊科（ED）就诊情况的差异。此前尚无研究在全国范围内对无家可归者的急诊科使用情况进行过调查。
分析全国范围内无家可归者对急诊科的利用情况。
数据取自2005年全国医院门诊医疗调查。使用可调用SAS的SUDAAN软件得出全国性估计数据。结果。2005年全国急诊科就诊人次达1.15亿，其中无家可归者就诊472,922人次。与非无家可归者相比，这些患者更有可能乘坐救护车前来就诊且未参保。两组的住院率和分诊紧急程度相似，不过无家可归者的诊断检查有增加趋势。
与非无家可归者相比，2005年前往急诊科就诊的无家可归者尽管分诊紧急程度和住院率相似，但更有可能乘坐救护车前来就诊，且参保可能性更小。
