Aims:To identify the factors associated with good-quality bystander cardiopulmonary resuscitation (BCPR). Multiple logistic regression analysis indicated that multiple rescuers (odds ratio=2.8, 95% CI: 1.5-5.6), bystander-initiated BCPR (2.7, 1.1-7.3), non-elderly bystanders (1.9, 1.1-3.2), occurrence in the central region (2.1, 1.3-3.3) and duration of BCPR (1.1, 1.0-1.1) were associated with good-quality BCPR. Moreover, good-quality BCPR was initiated earlier after recognition/witness of cardiac arrest compared with poor-quality BCPR (3 vs. 4 min, p=0.0052).
MethodsThe rate of neurologically favourable survival at one year was 2.7% and 0% in the good-quality and poor-quality groups, respectively (p=0.1357).
Conclusions:The presence of multiple rescuers and bystander-initiated CPR are predominantly associated with good-quality BCPR.
