title: Knowledge and preferences regarding cardiopulmonary resuscitation: A survey among older patients.
abstract: OBJECTIVE
  Survival rates following cardiopulmonary resuscitation (CPR) are low for older people, and are associated with a high risk of neurological damage. This study investigated the relationship between the preferences, knowledge of survival chances, and characteristics among older people regarding CPR.
  
  
  METHODS
  A cross-sectional, self-administrated survey was distributed by researchers to 600 patients aged at least 50 years. The 14-question survey tool was used to collect basic demographic data, knowledge about CPR, and preference for CPR. We performed binary logistic regression analysis to predict whether patients wanted to receive CPR or not.
  
  
  RESULTS
  The response rate was 48%. Most respondents (84%) predicted the estimated survival rate to be higher than the actual rate. Patients were significantly less likely to want to receive CPR if they correctly estimated the survival rate, had ever contemplated CPR, were older, or female. Discussing CPR with a doctor had no influence on patient preference for CPR.
  
  
  CONCLUSIONS
  Older patients choose to receive CPR based on incorrect knowledge.
  
  
  CONCLUSIONS
  Doctors should be aware of the impact of knowing the true chances of survival on patient preference for CPR. Knowledge and skills need to be updated to provide this information to patients.
