Public perception of and willingness to perform bystander CPR in Japan

Immediate bystander cardiopulmonary resuscitation (CPR) is the most essential factor for life saving in out-of-hospital cardiac arrest patients. We investigated the characteristics associated with willingness to attempt CPR among the Japanese general population.

We randomly selected 2400 persons from all over Japan and conducted a questionnaire survey regarding their knowledge, experiences of and attitudes toward CPR. We performed descriptive statistics followed by multivariable logistic regression analyses.

A total of 1132 persons (47%) completed the questionnaire. Only 13% of the subjects were willing to attempt bystander CPR for their families and friends, and 7% were willing to attempt bystander CPR for strangers. Willingness to attempt CPR was independently associated with office workers or skilled workers [odds ratio (OR) 1.8; 95% confidence interval (CI): 1.1-2.7], having trained in CPR [OR: 3.1; 95% CI: 2.1-4.6], actual experience with CPR [OR: 3.8; 95% CI: 1.7-8.3], and having friends with heart diseases [OR: 1.8; 95% CI: 1.05-3.0]. Having trained in CPR was independently associated with younger age [OR: 1.6; 95% CI: 1.2-2.1], office workers or skilled workers [OR: 1.5; 95% CI: 1.1-2.0], having driver's license [OR: 1.7; 95% CI: 1.2-2.4] and awareness of AED placement in a public space [OR: 2.1; 95% CI: 1.4-3.1].

Experience of CPR training closely associated with willingness to attempt CPR, and awareness of AED in a public space are significant factors in CPR training. AED placement might call attention to CPR training and develops willingness to attempt CPR.
