Don't stop your heart in front of your family: family as a bystander is associated with poor outcome of bystander-witnessed, bystander-CPR-performed out-of-hospital cardiac arrest
Critical Care volume 16, Article number: P272 (2012)
Early CPR with a considerable quality is essential for survival from out-of-hospital cardiac arrest (OHCA). This study was conducted to test our hypothesis that the relation of the bystander to the victim may affect the outcomes of OHCAs.
From a Japanese nationwide database for 431,968 OHCAs that occurred from January 2005 to December 2008, we extracted and then analyzed 45,248 bystander-witnessed, bystander-CPR-performed OHCAs without any involvement of physicians. Backgrounds, characteristics and outcomes were compared among the three groups of OHCAs categorized by the bystander's relation to victims. Multiple logistic regression analysis was applied to clarify if the relation may affect the 1-month survival with favourable neurological outcomes.
When the bystander was family, CPR was more frequently initiated following telephone-assisted instruction and the interval between collapse and bystander CPR was significantly prolonged. Univariate analysis followed by multiple logistic regression analysis revealed that family as a CPR performer significantly decreases the 1-month survival with favourable neurological outcomes. See Tables 1 and 2.
Despite educational efforts, most family members do not appear to be good CPR performers. The first responder system that enables a good CPR performer to reach the scene quickly may be needed for OHCAs witnessed by the family.
