Background: Bystander cardiopulmonary resuscitation can improve the survival rate of patients with out-of-hospital cardiac arrest. Teaching cardiopulmonary resuscitation in schools by teachers is one of the ways to increase the number of bystanders who can perform cardiopulmonary resuscitation. Nevertheless, there have been no studies on the readiness of teachers in Hong Kong to teach cardiopulmonary resuscitation in their schools. Objective: To assess whether secondary school teachers are prepared to teach their students cardiopulmonary resuscitation. Methods: This was a questionnaire survey. Teachers from 22 local secondary schools were recruited. The questionnaires were designed with questions covering their knowledge about cardiopulmonary resuscitation and attitudes towards teaching their students cardiopulmonary resuscitation. A knowledge score and attitude score were calculated. Result: 557 teachers completed the questionnaires. Most had never witnessed a cardiac arrest and over half of them had never been trained cardiopulmonary resuscitation or use of an automated defibrillator. About 25% of them answered all questions on knowledge wrong. Only 25% supported teaching cardiopulmonayr resuscitation in schools and 32% were willing to teach it. Legal liability was a major concern. Conclusion: Local teachers' readiness for teaching students cardiopulmonary resuscitation in secondary schools is likely poor. More efforts are required to raise their knowledge level on cardiopulmonary resuscitation and instill a positive attitude towards cardiopulmonary resuscitation education in schools.

Prehospital MEWS is useful in identifying non-trauma patients requiring LSI within 4 h of ED presentation. This may in turn enhance the triage accuracy in the ED in addition to clinical assessment.

Elderly suffering from cardiac arrest in residential care homes had a poor chance of survival. Except age, witnessed arrest, bystander defibrillation, and call to ED interval are modifiable predictors of survival. It is inappropriate to declare that resuscitating elderly in residential care homes is futile unless those factors have been fully addressed.

Ageing population is creating an imminent burden on the emergency service in Hong Kong. Previously unavailable epidemiological information about geriatric attendance to AEDs was described. This forms the basis for development of future studies concerning the medical services on this specific group of patients.
