急诊科（艾德）中的传染性个体带来交叉感染的巨大风险。有关艾德人际接触的复杂社会和空间结构的数据将有助于构建生物学上合理的传播风险模型，从而指导交叉感染控制。我们试图确定在一个大型的，繁忙的忙碌ED患者和工作人员之间的接触的数量和持续时间。这项前瞻性研究进行了2009年7月1日和2010年6月30日之间。每周随机选择两个12小时轮班进行研究。研究在一家城市医院的艾德急诊室进行。在计划的104例随机样本（78%）中有81个班次有可用的接触数据，在此期间有9183例患者就诊。其中，6062人（66%）被邀请参加，其中4732人（78%）同意参加。在这一年中，有88名工作人员参加了培训（占84%）。安装了射频识别（RFID）系统，艾德被分成89个不同的区域，因此任何区域中的两个人的共同存在意味着在空间上相距<1米的接触概率非常高。在研究观察期间，患者和工作人员被给予RFID标签佩戴。记录接触事件。根据接触的性质进一步细分，即，病人与病人，病人与员工，员工与员工。记录了293，171次接触事件，中位数为22次接触事件，每班每位参与者与不同个体有9次接触。工作人员与工作人员之间的互动比患者与患者或患者与工作人员之间的互动更多，时间更长。我们使用RFID来量化病人和工作人员之间的接触在一个忙碌ED。这些结果是有用的研究传染病的传播。通过了解在潜在传播中最重要的接触模式，可以实施更有效的预防策略。
Infectious individuals in an emergency department (ED) bring substantial risks of cross infection. Data about the complex social and spatial structure of interpersonal contacts in the ED will aid construction of biologically plausible transmission risk models that can guide cross infection control. We sought to determine the number and duration of contacts among patients and staff in a large, busy ED. This prospective study was conducted between 1 July 2009 and 30 June 2010. Two 12-hour shifts per week were randomly selected for study. The study was conducted in the ED of an urban hospital. There were 81 shifts in the planned random sample of 104 (78%) with usable contact data, during which there were 9183 patient encounters. Of these, 6062 (66%) were approached to participate, of which 4732 (78%) agreed. Over the course of the year, 88 staff members participated (84%). A radiofrequency identification (RFID) system was installed and the ED divided into 89 distinct zones structured so copresence of two individuals in any zone implied a very high probability of contact <1 meter apart in space. During study observation periods, patients and staff were given RFID tags to wear. Contact events were recorded. These were further broken down with respect to the nature of the contacts, i.e., patient with patient, patient with staff, and staff with staff. 293,171 contact events were recorded, with a median of 22 contact events and 9 contacts with distinct individuals per participant per shift. Staff-staff interactions were more numerous and longer than patient-patient or patient-staff interactions. We used RFID to quantify contacts between patients and staff in a busy ED. These results are useful for studies of the spread of infections. By understanding contact patterns most important in potential transmission, more effective prevention strategies may be implemented.
