Immediate resuscitation is necessary in order to achieve conscious survival for persons who have lost airways or pulses. However, current literature suggests that even in medically-trained personnel, CPR skills are forgotten shortly after certification.
HYPOTHESIS/PROBLEM: The purpose of this study was to determine the CPR skill and knowledge decay in those who are paid to respond to emergency situations within the workplace.
Using an unconscious victim scenario, the sequence and accuracy of CPR events were observed and recorded in 244 participants paid to act as first responders in large industrial or service industry settings.
A significant negative correlation was observed between days since training and a pre-CPR safety check variable, periodic checks for breathing and positioning. Many of the knowledge-related assessment skills (e.g., scene safety, emergency medical system (EMS) activation) appeared to deteriorate with time, although they could be contaminated by the repetition of training in those who had recertified one or more times. Skill-based components such as landmarking for chest compressions and controlling the airway declined in a more predictable fashion.
The results of this study suggest that repetition may be more important than days since last trained for skill and knowledge retention, and methods of "refreshing" skills should be examined. While skills deteriorate rapidly, changing frequency of certification is not necessarily the best way to increase retention of skill and knowledge.
为了使失去气道或脉搏的人能够有意识地存活下来,必须立即进行复苏。然而,目前的文献表明,即使是在接受过医学培训的人员中,心肺复苏术技能也会在认证后不久就被遗忘。
假设/问题:本研究的目的是确定那些有偿响应工作场所紧急情况的人,其心肺复苏术技能和知识的衰减情况。
在 244 名有偿在大型工业或服务行业环境中担任第一响应者的参与者中,使用无意识受害者场景,观察和记录心肺复苏术事件的顺序和准确性。
在培训后天数与进行 CPR 前安全检查变量(定期检查呼吸和体位)之间观察到显著的负相关。许多与知识相关的评估技能(例如,现场安全、紧急医疗系统(EMS)激活)似乎随着时间的推移而恶化,尽管对于那些已经重新认证一次或多次的人来说,这些技能可能会因重复培训而受到污染。基于技能的组件,例如胸部按压的地标定位和气道控制,以更可预测的方式下降。
这项研究的结果表明,重复可能比上次训练后的天数更重要,以保持技能和知识的保留,并且应该检查“更新”技能的方法。虽然技能会迅速下降,但改变认证频率不一定是提高技能和知识保留的最佳方法。
