Public knowledge and attitudes towards cardiopulmonary resuscitation in Hong Kong: telephone survey

Objectives: To investigate the public's knowledge and attitudes about cardiopulmonary resuscitation in Hong Kong. Design: Cross-sectional telephone survey. Setting: Hong Kong. Participants: Hong Kong residents aged 15 to 64 years. Main outcome measures: The knowledge and attitudes towards cardiopulmonary resuscitation. Results: Among the 1013 respondents, only 214 (21%) reported that they had received cardiopulmonary resuscitation training. The majority (72%) of these trained respondents had had their latest training more than 2 years earlier. The main reasons for not being involved in cardiopulmonary resuscitation training included lack of time or interest, and "not necessary". People with full-time jobs and higher levels of education were more likely to have such training. Respondents stating they had received cardiopulmonary resuscitation training were more willing to try it if needed at home (odds ratio=3.3; 95% confidence interval, 2.4-4.6; P<0.001) and on strangers in the street (4.3; 3.1-6.1; P<0.001) in case of emergencies. Overall cardiopulmonary resuscitation knowledge of the respondents was low (median=1, out of 8). Among all the respondents, only four of them (0.4%) answered all the questions correctly. Conclusions: Knowledge of cardiopulmonary resuscitation was still poor among the public in Hong Kong and the percentage of population trained to perform it was also relatively low. Efforts are needed to promote educational activities and explore other approaches to skill reinforcement and refreshment. Besides, we suggest enacting laws to protect bystanders who offer cardiopulmonary resuscitation, and incorporation of relevant training course into secondary school and college curricula.
