CPR knowledge and attitudes among high school students aged 15-16 in Hong Kong

Background: Sudden cardiac arrest is a serious public health problem in Hong Kong, with up to 85% of victims not surviving to hospital admission. International research findings show that teaching cardiopulmonary resuscitation (CPR) to lay bystanders can significantly improve out-of-hospital survival rates. A particular target group for CPR training and education is high school students. Since the commonest site of sudden cardiac deaths in Hong Kong occur at home, school-age adolescents are likely to be the only available bystanders in many emergent situations. Design: Questionnaire survey. Methods: This study investigated CPR knowledge and attitudes of 383 students aged 15-16 years across 18 schools in Hong Kong to understand barriers and facilitators for CPR delivery. A questionnaire pilot tested and validated by a panel of health professionals was distributed to students, using a convenience sampling methodology. Results: Most students (87%) had not received CPR training, with common reasons for not attending being lack of time, lack of interest and not sure where to attend a course. Results of Mann Whitney U tests indicated that students who had received training scored significantly (p<0.05) higher on factual knowledge and also attitudes toward CPR training than those without training. There were no gender differences. Most students reported that they would attempt to perform CPR in a cardiac arrest situation, even if they had not received training, because they believed that CPR could increase the survival rate and it was morally the right thing to do. Conclusions: Teaching CPR to Hong Kong school students is an effective way to develop the next generation of emergency first responders.
