A 10-month direct mail campaign was implemented to increase use of emergency medical services via 911 calls and to reduce prehospital delay for individuals experiencing acute myocardial infarction symptoms.
This prospective, randomized, controlled trial involved three intervention groups (receiving brochures with informational, emotional, or social messages) and a control group.
Intervention effects were not observed except for individuals who had a history of acute myocardial infarction and who were discharged with a diagnosis of acute myocardial infarction; their 911 use was meaningfully higher in each intervention group than in the control group.
The mailings affected only the individuals at greatest risk.
开展了一项为期10个月的直邮活动,以通过911电话增加紧急医疗服务的使用,并减少急性心肌梗死症状患者的院前延误。
这项前瞻性、随机对照试验涉及三个干预组(分别接收包含信息性、情感性或社会性信息的宣传册)和一个对照组。
除有急性心肌梗死病史且出院诊断为急性心肌梗死的个体外,未观察到干预效果;在每个干预组中,这些个体拨打911的次数显著高于对照组。
邮件仅对风险最高的个体产生了影响。
