Objective Between 2009 and 2013, the National Heart Foundation of Australia ran mass media campaigns to improve Australian’s awareness of acute coronary syndrome (ACS) symptoms and the need to call emergency medical services (EMS). This study examined the impact of this campaign on emergency department (ED) presentations and EMS use in Victoria, Australia. Methods The Victorian Department of Health and Human Services provided data for adult Victorian patients presenting to public hospitals with an ED diagnosis of ACS or unspecified chest pain (U-CP). We modelled changes in the incidence of ED presentations, and the association between the campaign period and (1) EMS arrival and (2) referred to ED by a general practitioner (GP). Models were adjusted for increasing population size, ACS subtype and demographics. Results Between 2003 and 2015, there were 124 632 eligible ED presentations with ACS and 536 148 with U-CP. In patients with ACS, the campaign period was associated with an increase in ED presentations (incidence rate ratio: 1.11; 95% CI 1.07 to 1.15), a decrease in presentations via a GP (adjusted OR (AOR): 0.77; 95% CI 0.70 to 0.86) and an increase in EMS use (AOR: 1.10; 95% CI 1.05 to 1.17). Similar, but smaller associations were seen in U-CP. Conclusions The Warning Signs Campaign was associated with improvements in treatment seeking in patients with ACS—including increased EMS use. The increase in ACS ED presentations corresponds with a decrease in out-of-hospital cardiac arrest over this time. Future education needs to focus on improving EMS use in ACS patient groups where use remains low. No data are available. Data are not available from the authors due to contractual arrangements.

大众媒体运动对急性冠状动脉综合征的介绍和救护车使用的影响

目标 2009 年至 2013 年期间，澳大利亚国家心脏基金会开展了大众媒体宣传活动，以提高澳大利亚人对急性冠状动脉综合征 (ACS) 症状和呼叫紧急医疗服务 (EMS) 需求的认识。本研究考察了该活动对澳大利亚维多利亚州急诊科 (ED) 演示和 EMS 使用的影响。方法 维多利亚州卫生和公共服务部提供了在公立医院就诊的维多利亚州成年患者的数据，他们的急诊科诊断为 ACS 或不明胸痛 (U-CP)。我们模拟了 ED 就诊发生率的变化，以及运动期与 (1) EMS 到达和 (2) 全科医生 (GP) 转诊 ED 之间的关联。模型针对增加的人口规模、ACS 亚型和人口统计数据进行了调整。结果 2003 年至 2015 年间，ACS 有 124 632 例符合条件的 ED 就诊，U-CP 有 536 148 例。在 ACS 患者中，运动期与 ED 就诊的增加有关（发生率比：1.11；95% CI 1.07 至 1.15），通过 GP 就诊的减少（调整后的 OR (AOR)：0.77；95% CI 0.70 到 0.86）和 EMS 使用的增加（AOR：1.10；95% CI 1.05 到 1.17）。在 U-CP 中发现了类似但较小的关联。结论 警告标志运动与 ACS 患者寻求治疗的改善有关，包括增加 EMS 的使用。ACS ED 就诊的增加与这段时间内院外心脏骤停的减少相对应。未来的教育需要重点关注在使用率仍然很低的 ACS 患者群体中改善 EMS 的使用。没有可用的数据。由于合同安排，无法从作者处获得数据。维多利亚州卫生与公众服务部可应要求提供数据。
