Swift defibrillation by lay responders using automated external defibrillators (AEDs) increases survival in out-of-hospital cardiac arrest (OHCA). This study evaluated newly designed yellow-red vs. commonly used green-white signage for AEDs and cabinets and assessed public attitudes to using AEDs during OHCA.
New yellow-red signage was designed to enable easy identification of AEDs and cabinets. A prospective, cross-sectional study of the Australian public was conducted using an electronic, anonymised questionnaire between November 2021 and June 2022. The validated net promoter score investigated public engagement with the signage. Likert scales and binary comparisons evaluated preference, comfort and likelihood of using AEDs for OHCA.
The yellow-red signage for AED and cabinet was preferred by 73.0% and 88%, respectively, over the green-white counterparts. Only 32% were uncomfortable with using AEDs, and only 19% indicated a low likelihood of using AEDs in OHCA.
The majority of the Australian public surveyed preferred yellow-red over green-white signage for AED and cabinet and indicated comfort and likelihood of using AEDs in OHCA. Steps are necessary to standardise yellow-red signage of AED and cabinet and enable widespread availability of AEDs for public access defibrillation.
非专业急救人员使用自动体外除颤器（AED）进行快速除颤可提高院外心脏骤停（OHCA）患者的生存率。本研究评估了新设计的黄红色与常用的绿白色AED及存放柜标识，并调查了公众在院外心脏骤停期间使用AED的态度。
设计新的黄红色标识以便于识别AED及存放柜。2021年11月至2022年6月期间，采用电子匿名问卷对澳大利亚公众进行了一项前瞻性横断面研究。通过经过验证的净推荐值来调查公众对该标识的接受程度。使用李克特量表和二元比较法评估公众对院外心脏骤停使用AED的偏好、舒适度及可能性。
与绿白色标识相比，分别有73.0%和88%的受访者更喜欢AED及存放柜的黄红色标识。只有32%的人对使用AED感到不适，只有19%的人表示在院外心脏骤停时使用AED的可能性较低。
参与调查的大多数澳大利亚公众更喜欢AED及存放柜的黄红色标识而非绿白色标识，并表示在院外心脏骤停时使用AED感到舒适且有使用的可能性。有必要采取措施规范AED及存放柜的黄红色标识，并使AED广泛可供公众用于心脏除颤。
