We evaluated the effects of a community public education campaign that encouraged patients to quickly call 911 after the onset of acute myocardial infarction (AMI) symptoms.
The media campaign focused on residents 50 years of age or older in King County, Washington, which has a population of 1.5 million (1990 census).
We determined 911 responses for chest pain, emergency department visits for AMI symptoms, the number of patients admitted to a CCU with an admitting diagnosis of rule-out MI, and the number of confirmed AMIs before and after the campaign.
The number of emergency medical services (EMS) responses (911 runs) for patients 50 years of age or older experiencing AMI symptoms increased significantly during the media campaign. ED visits for chest pain also increased significantly during the campaign, as did the number of patients 50 years of age or older admitted to a King County CCU with an admitting diagnosis of rule-out MI. Each of the above increases tapered--with time after the media campaign but remained above baseline.
An intense public education campaign can significantly increase EMS use, ED visits, and CCU admissions for AMI symptoms. However, these effects taper off with time after the campaign.
我们评估了一项社区公共教育活动的效果，该活动鼓励患者在急性心肌梗死（AMI）症状出现后迅速拨打911。
该媒体活动聚焦于华盛顿州金县50岁及以上的居民，该县人口为150万（1990年人口普查数据）。
我们确定了活动前后因胸痛拨打911的次数、因AMI症状前往急诊科就诊的次数、以排除心肌梗死为入院诊断入住冠心病监护病房（CCU）的患者数量以及确诊AMI的患者数量。
在媒体活动期间，50岁及以上出现AMI症状的患者的紧急医疗服务（EMS）响应次数（911呼叫）显著增加。活动期间，因胸痛前往急诊科就诊的次数也显著增加，50岁及以上以排除心肌梗死为入院诊断入住金县CCU的患者数量同样如此。上述各项增加在媒体活动结束后随时间逐渐减少，但仍高于基线水平。
一场密集的公共教育活动可显著增加因AMI症状而使用EMS、前往急诊科就诊以及入住CCU的人数。然而，这些效果在活动结束后会随时间逐渐减弱。
