Cardiopulmonary resuscitation (CPR) is a medical intervention whose practice is highly regulated. In Switzerland, when dealing with elderly patients, physicians decide whether resuscitation would be medically indicated in the case of a cardiorespiratory arrest and discuss it with the patient. The quality of the information provided by the physician during the first encounter with the patient may influence the latter's preferences. However, many studies emphasize the difficulties that hospital physicians face when engaging in this conversation. In order to promote a care provision that is both adequate and respectful of elderly patients, more attention should be devoted to the obstacles that hinder communication on this subject and to the resources available to physicians.
