Overestimation of Survival Rates of Cardiopulmonary Resuscitation Is Associated with Higher Preferences to Be Resuscitated: Evidence from a National Survey of Older Adults in Switzerland.

Many older adults in Switzerland overestimate the survival rates of cardiopulmonary resuscitation (CPR).The study reveals that individuals with accurate knowledge of CPR survival rates are more likely to refuse resuscitation in case of cardiac arrest.Overestimation of CPR survival rates may lead to a mismatch between individuals' preferences for CPR and their actual end-of-life care decisions.Improving the general population's knowledge of CPR survival rates is crucial to ensure informed decision making and effective advance care planning.
