There has been in increase in the use of systems for organizing lay responders for suspected out-of-hospital cardiac arrests (OHCAs) dispatch using smartphone-based technology. The purpose is to increase survival rates; however, such systems are dependent on people’s commitment to becoming a lay responder. Knowledge about the characteristics of such volunteers and their motivational factors is lacking. Therefore, we explored characteristics and quantified the underlying motivational factors for joining a smartphone-based cardiopulmonary resuscitation (CPR) lay responder system. In this descriptive cross-sectional study, 800 consecutively recruited lay responders in a smartphone-based mobile positioning first-responder system (SMS-lifesavers) were surveyed. Data on characteristics and motivational factors were collected, the latter through a modified version of the validated survey “Volunteer Motivation Inventory” (VMI). The statements in the VMI, ranked on a Likert scale (1–5), corresponded to(a) intrinsic (an inner belief of doing good for others) or (b) extrinsic (earning some kind of reward from the act) motivational factors. A total of 461 participants were included in the final analysis. Among respondents, 59% were women, 48% between 25 and 39 years of age, 37% worked within health care, and 66% had undergone post-secondary school. The most common way (44%) to learn about the lay responder system was from a CPR instructor. A majority (77%) had undergone CPR training at their workplace. In terms of motivation, where higher scores reflect greater importance to the participant, intrinsic factors scored highest, represented by the category values (mean 3.97) followed by extrinsic categories reciprocity (mean 3.88) and self-esteem (mean 3.22). This study indicates that motivation to join a first responder system mainly depends on intrinsic factors, i.e. an inner belief of doing good, but there are also extrinsic factors, such as earning some kind of reward from the act, to consider. Focusing information campaigns on intrinsic factors may be the most important factor for successful recruitment. When implementing a smartphone-based lay responder system, CPR instructors, as a main information source to potential lay responders, as well as the workplace, are crucial for successful recruitment.

加入非专业响应系统调度院外心脏骤停的特征和动机因素

使用基于智能手机的技术来组织非专业急救人员进行疑似院外心脏骤停 (OHCA) 调度的系统的使用有所增加。目的是提高存活率；然而，这样的系统依赖于人们成为非专业响应者的承诺。缺乏对此类志愿者的特征及其激励因素的了解。因此，我们探索了特征并量化了加入基于智能手机的心肺复苏 (CPR) 非专业人员响应系统的潜在动机因素。在这项描述性横断面研究中，对基于智能手机的移动定位急救系统（SMS-lifesavers）中连续招募的 800 名非专业急救人员进行了调查。收集了有关特征和动机因素的数据，后者通过经过验证的调查“志愿者动机清单”（VMI）的修改版本。VMI 中的陈述，按李克特量表 (1-5) 排名，对应于 (a) 内在（为他人做好事的内在信念）或 (b) 外在（从行为中获得某种奖励）动机因素. 最终分析共纳入 461 名参与者。在受访者中，59% 是女性，48% 年龄在 25 至 39 岁之间，37% 从事医疗保健工作，66% 接受过高等教育。了解非专业急救人员系统的最常见方式 (44%) 来自心肺复苏术教练。大多数人（77%）在他们的工作场所接受过心肺复苏术培训。在动机方面，分数越高表明对参与者的重要性越大，内在因素得分最高，由类别值表示（平均 3. 97）其次是外在类别互惠（平均 3.88）和自尊（平均 3.22）。这项研究表明，加入急救系统的动机主要取决于内在因素，即做好事的内在信念，但也有外在因素，例如从行为中获得某种奖励，需要考虑。将宣传活动的重点放在内在因素上可能是成功招聘的最重要因素。在实施基于智能手机的非专业急救人员系统时，CPR 讲师作为潜在非专业急救人员以及工作场所的主要信息来源，对于成功招聘至关重要。行善的内在信念，但也有外在因素，例如从行为中获得某种奖励，需要考虑。将宣传活动的重点放在内在因素上可能是成功招聘的最重要因素。在实施基于智能手机的非专业急救人员系统时，CPR 讲师作为潜在非专业急救人员以及工作场所的主要信息来源，对于成功招聘至关重要。行善的内在信念，但也有外在因素，例如从行为中获得某种奖励，需要考虑。将宣传活动的重点放在内在因素上可能是成功招聘的最重要因素。在实施基于智能手机的非专业急救人员系统时，CPR 讲师作为潜在非专业急救人员以及工作场所的主要信息来源，对于成功招聘至关重要。
