目的：为了更好地了解如何将中风事件传达给 9-1-1 电信员，以及电信员和紧急医疗服务 (EMS) 人员如何响应此类呼叫。方法：作者确定了 104 名出院诊断为中风或短暂性脑缺血发作的患者，这些患者在 1999 年和 2000 年期间被救护车送往北卡罗来纳州两个县的医院。救护车呼叫报告被摘要并链接到9-1-1 呼叫中心录音带，经过转录和验证。结果：在 104 个电话中，44 个是医务人员拨打的，38 个是家庭成员拨打的，8 个是旁观者或邻居拨打的，5 个电话未确定，3 个是其他非医务人员拨打的。只有六次 (6%) 是患者拨打的电话。最常见的症状是精神状态改变（40%）、行走困难（32%）、言语障碍（27%）和呼吸异常（27%）。尽管“中风”一词经常被使用（45%），但 9-1-1 电信接线员仅在 31% 的病例中将这些电话归类为中风。然而，在大多数情况下（79%），护理人员是最优先被派遣的。从派出 EMS 到患者到达医院的中位时间为 41 分钟，其中大约一半时间是在现场度过的。 结论：虽然典型的中风症状经常被描述，但电话通常不会被电信公司归类为“中风”。尽管如此，由于通话期间报告的症状，大多数病例都被电信公司视为高度优先处理。
OBJECTIVE: To obtain a better understanding of how stroke events are communicated to 9-1-1 telecommunicators, and how telecommunicators and emergency medical services (EMS) personnel respond to such calls.METHODS: The authors identified 104 patients with a hospital discharge diagnosis of stroke or transient ischemic attack who were transported to hospital by ambulance in two North Carolina counties during 1999 and 2000. Ambulance call reports were abstracted and linked to 9-1-1 call center audiotapes, which were transcribed and verified.RESULTS: Of the 104 calls, 44 were made by medical personnel, 38 by a family member, eight by a bystander or neighbor, five undetermined, and three by other nonmedical personnel. In only six instances (6%) was the call placed by the patient. The most common symptoms reported were altered mental status (40%), trouble walking (32%), impaired speech (27%), and abnormal breathing (27%). Although the word "stroke" was often used (45%), 9-1-1 telecommunicators classified the calls as a stroke in only 31% of cases. However, in the majority of cases (79%), paramedics were dispatched at the highest priority. The median time from dispatch of EMS to patient arrival at the hospital was 41 minutes, approximately half of which was spent at the scene.CONCLUSION: Although typical stroke symptoms are commonly described, calls are often not classified as "strokes" by telecommunicators. Nevertheless, because of the symptoms reported during the calls, the majority of cases are treated as high priority by telecommunicators.
