Background:Similar to many Asian cities, there is no statutory provision for the determination of the duty borne by bystander first aiders when assisting victims in Hong Kong.Objectives:The aim of this study was to explore the views of a Good Samaritan Law by first-aid learners in Hong Kong.Methods:A cross-sectional survey was conducted among first-aid course participants from the two largest training providers in Hong Kong using a self-administered questionnaire.Results:In total, 1223 questionnaires were completed and returned. Only 12.1% (147/1211) of participants have ever heard of Good Samaritan Law. After a short description of Good Samaritan Law was provided, 71.4% (848/1188) agreed or strongly agreed on a Likert-type scale that a Good Samaritan Law is necessary; 95.2% (1148/1223) support the enactment of a Good Samaritan Law in Hong Kong.Conclusion:The majority of first-aid learners in Hong Kong supported the enactment of Good Samaritan Law. Overcoming the fear of litigation and improving bystander cardiopulmonary resuscitation rate is a priority for improving survival rates from sudden cardiac arrest in Hong Kong.
