Early bystander cardiopulmonary resuscitation (CPR) is one of the most important predictors of out-of-hospital cardiac arrests (OHCA) survival. There is a dearth of literature on CPR engagement in countries such as Ghana, where cardiovascular events are increasingly prevalent. In this study, we sought to evaluate Ghanaians' knowledge of and attitudes towards bystander CPR, in the context of the country's nascent emergency medicine network.
Capitalizing on the growing ubiquity and use of social media across the country, we used a novel social media sampling strategy for this study. We created, pre-tested, and distributed an online survey, using the two most utilized social media platforms in Ghana: WhatsApp and Facebook. An airtime data incentive of 5 US dollars, worth between 5 and 10 GB of cellular data based on mobile phone carrier, was provided as incentive. Inclusion criteria were (1) ≥ 18 years of age, (2) living in Ghana. Survey participants were encouraged to distribute the survey within their own networks to expand its reach. We stratified participants' responses by healthcare affiliation, and further grouped healthcare workers into ambulance and non-ambulance personnel. We used chi-square (χ2)/Fisher's Exact tests to compare differences in responses between the groups. Based on the question "have you ever heard of CPR?", an alpha of 0.05 and a 95% confidence interval, we expected to have 80% power to detect a 15% difference in responses between lay and healthcare providers with an estimated sample size of 246 study participants.
The survey was launched on 8 July 2019 and closed approximately 51 h post-launch. With a 64% completion rate and 479 unique survey completions, the study was overpowered at 96% power, to detect differences in responses between the groups. There was geographic representation across all 10 historic regions of Ghana. Over half (57.8%, n = 277) of the respondents were non-medically affiliated, and 71.9% were women. Healthcare workers were more aware of CPR than lay respondents (96.5% vs 68.1%; p < 0.001). Eighty-five percent of respondents were aware that CPR involves chest compressions, and almost 70% indicated that "mouth to mouth" is a necessary component of CPR. Fewer than 10% were unwilling to administer CPR. Lack of skills (44.9%) and fear of causing harm (25.5%) were barriers noted by respondents for not administering CPR. Notably, a quarter of ambulance workers reported never having received CPR training. If they were to witness a collapse, 62.0% would call an ambulance, and 32.6% would hail a taxi.
The majority of participants are willing to perform CPR. Contextualized training that emphasizes hands-only CPR and builds participants' confidence may increase bystander willingness and engagement.
早期旁观者心肺复苏术(CPR)是院外心脏骤停(OHCA)存活的最重要预测因素之一。在加纳等心血管事件日益普遍的国家,关于CPR参与情况的文献匮乏。在本研究中,我们试图在该国新兴的急诊医学网络背景下,评估加纳人对旁观者CPR的知识和态度。
利用社交媒体在该国日益普及和广泛使用的情况,我们在本研究中采用了一种新颖的社交媒体抽样策略。我们使用加纳两个最常用的社交媒体平台:WhatsApp和Facebook,创建、预测试并分发了一项在线调查。提供了价值5美元的通话时间数据奖励,根据手机运营商的不同,相当于5至10GB的移动数据作为激励。纳入标准为:(1)年龄≥18岁;(2)居住在加纳。鼓励调查参与者在自己的社交网络内分发调查以扩大覆盖面。我们按医疗保健隶属关系对参与者的回答进行分层,并将医护人员进一步分为救护车和非救护车人员。我们使用卡方(χ2)/费舍尔精确检验来比较各组回答的差异。基于“你是否听说过CPR?”这个问题,设定α为0.05和95%置信区间,预计在估计样本量为246名研究参与者的情况下,有80%的把握检测出非专业人员和医护人员回答之间15%的差异。
该调查于2019年7月8日启动,启动后约51小时结束。完成率为64%,共有479份独特的调查完成,该研究的检验效能为96%,足以检测出各组回答之间的差异。加纳所有10个历史区域都有地理代表性。超过一半(57.8%,n = 277)的受访者与医疗行业无关,71.9%为女性。医护人员比非专业受访者更了解CPR(96.5%对68.1%;p < 0.001)。85%的受访者知道CPR包括胸部按压,近70%表示“口对口”是CPR的必要组成部分。不到10%的人不愿意实施CPR。受访者指出缺乏技能(44.9%)和害怕造成伤害(25.5%)是不实施CPR的障碍。值得注意的是,四分之一的救护车工作人员报告从未接受过CPR培训。如果他们目睹有人晕倒,62.0%的人会叫救护车,3
