Lay Bystanders' Perspectives on What Facilitates Cardiopulmonary Resuscitation and Use of Automated External Defibrillators in Real Cardiac Arrests
Background
Many patients who suffer an outâofâhospital cardiac arrest will fail to receive bystander intervention (cardiopulmonary resuscitation [CPR] or defibrillation) despite widespread CPR training and the dissemination of automated external defibrillators (AEDs). We sought to investigate what factors encourage lay bystanders to initiate CPR and AED use in a cohort of bystanders previously trained in CPR techniques who were present at an outâofâhospital cardiac arrest.
Methods and Results
Oneâhundred and twentyâeight semistructured qualitative interviews with CPRâtrained lay bystanders to consecutive outâofâhospital cardiac arrest, where an AED was present were conducted (from January 2012 to April 2015, in Denmark). Purposive maximum variation sampling was used to establish the breadth of the bystander perspective. Twentyâsix of the 128 interviews were chosen for further inâdepth analyses, until data saturation. We used crossâsectional indexing (using software), and inductive inâdepth thematic analyses, to identify those factors that facilitated CPR and AED use. In addition to prior handsâon CPR training, the following were described as facilitators: prior knowledge that intervention is crucial in improving survival, cannot cause substantial harm, and that the AED will provide guidance through CPR; prior handsâon training in AED use; during CPR performance, teamwork (ie, support), using the AED voice prompt and a ventilation mask, as well as demonstrating leadership and feeling a moral obligation to act.
Conclusions
Several factors other than previous handsâon CPR training facilitate lay bystander instigation of CPR and AED use. The recognition and modification of these factors may increase lay bystander CPR rates and patient survival following an outâofâhospital cardiac arrest.
