Nas J, et al. - Researchers reported the influence of bystander cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) use on the outcomes of out-of-hospital cardiac arrests (OHCAs) in the Nijmegen area in a prospective resuscitation registry wherein non-traumatic OHCA cases from 2013–2016 and historical controls from 2008–2011, totaling to 349 overall subjects, were included and arrests witnessed by the emergency medical service (EMS) were excluded. In both cohorts, bystander CPR and AED use were found to be independently related to survival. A significant improvement, up to 40–50%, in survival to discharge was reported in patients admitted after OHCA vs other Dutch registries. These results seemed to be resulting from increased bystander CPR and the doubled use of AEDs.
