The 'chain of survival'-including early call for help, early cardiopulmonary resuscitation (CPR) and early defibrillation-represents the most beneficial approach for favourable patient outcome after out-of-hospital cardiac arrest (OHCA). Despite increasing numbers of publicly accessible automated external defibrillators (AED) and interventions to increase public awareness for basic life support (BLS), the number of their use in real-life emergency situations remains low.
In this prospective population-based cross-sectional study, a total of 501 registered inhabitants of Vienna (Austria) were randomly approached via telephone calls between 08/2014 and 09/2014 and invited to answer a standardized questionnaire in order to identify public knowledge and awareness of BLS and AED-use.
We found that more than 52 percent of participants would presume OHCA correctly and would properly initiate BLS attempts. Of alarming importance, only 33 percent reported that they would be willing to perform CPR and 50 percent would use an AED device. There was a significantly lower willingness to initiate BLS attempts (male: 40% vs. female: 25%; OR: 2.03 [95%CI: 1.39-2.98]; p<0.001) and to use an AED device (male: 58% vs. female: 44%; OR: 1.76 [95%CI: 1.26-2.53]; p = 0.002) in questioned female individuals compared to their male counterparts. Interestingly, we observed a strongly decreasing level of knowledge and willingness for BLS attempts (-14%; OR: 0.72 [95%CI: 0.57-0.92]; p = 0.027) and AED-use (-19%; OR: 0.68 [95%CI: 0.54-0.85]; p = 0.001) with increasing age.
We found an overall poor knowledge and awareness concerning BLS and the use of AEDs among the Viennese population. Both female and elderly participants reported the lowest willingness to perform BLS and use an AED in case of OHCA. Specially tailored programs to increase awareness and willingness among both the female and elderly community need to be considered for future educational interventions.
“生存链”——包括早期呼救、早期心肺复苏（CPR）和早期除颤——是院外心脏骤停（OHCA）后患者获得良好预后的最有益方法。尽管越来越多的公共场所可获得自动体外除颤器（AED），并且采取了提高公众对基本生命支持（BLS）认识的干预措施，但在现实紧急情况下使用 AED 的数量仍然很低。
在这项前瞻性基于人群的横断面研究中，2014 年 8 月至 9 月期间，通过电话随机联系了维也纳（奥地利）的 501 名注册居民，并邀请他们回答标准化问卷，以确定公众对 BLS 和 AED 使用的了解和认识。
我们发现，超过 52%的参与者能够正确判断 OHCA，并正确开始 BLS 尝试。令人担忧的是，只有 33%的人表示愿意进行 CPR，而 50%的人愿意使用 AED 设备。在开始 BLS 尝试（男性：40%比女性：25%；OR：2.03[95%CI：1.39-2.98]；p<0.001）和使用 AED 设备（男性：58%比女性：44%；OR：1.76[95%CI：1.26-2.53]；p=0.002）方面，女性的意愿明显低于男性。有趣的是，我们观察到，随着年龄的增长，对 BLS 尝试（-14%；OR：0.72[95%CI：0.57-0.92]；p=0.027）和 AED 使用（-19%；OR：0.68[95%CI：0.54-0.85]；p=0.001）的知识和意愿呈明显下降趋势。
我们发现维也纳居民对 BLS 和 AED 使用的整体了解和认识较差。女性和老年参与者报告在 OHCA 情况下进行 BLS 和使用 AED 的意愿最低。需要考虑针对女性和老年社区的专门提高认识和意愿的计划，以用于未来的教育干预措施。
