Life-sustaining treatments: what doctors do, what they want for themselves and what elderly persons want.

In view of the current social dilemmas regarding the use of life-sustaining treatments (LST) at the end of life, the purpose of the study was to reveal sources of interpersonal and intrapersonal conflict among the most involved parties, in a society where open doctor-patient communication about end-of-life treatment is rare. Two comparative analyses were conducted: (a) between physicians' practice and elderly persons' preferences regarding the use of different life-sustaining treatments in different illness conditions, and (b) between physicians' hypothetical practice for an elderly person in a metastatic cancer condition, elderly persons' preferences and physicians' preferences for themselves, should they be in the same illness condition. Data were collected in Israel from 339 physicians working in two medical centers, and from a random sample of 987 elderly persons. Attitudes and practice regarding artificial tube feeding, mechanical ventilation and cardiopulmonary resuscitation (CPR) in three different illness conditions were evaluated by close-ended questions. The findings indicate disagreements between the elderly and the physicians on a number of issues: in general, physicians report that they would use more LST than what the elderly report that they would want. Physicians differentiate among different illness conditions and different LST more than elderly persons do. Physicians are more likely to use artificial feeding than CPR, while elderly persons prefer the use of CPR more than artificial feeding. The comparison of physicians' hypothetical practice, the wishes of the elderly, and physicians' wishes for themselves regarding the use of LST in a metastatic cancer condition, shows that physicians would use LST differently from what the elderly want, and that they want less LST for themselves than they would order for elderly patients. The discrepancies found between the physicians' practice and the elderly persons preferences reflect differences in perceptions of artificial feeding and a lack of public knowledge regarding the effectiveness of CPR. They also reflect differences in attitudes regarding the prolongation of life in various illness conditions. The discrepancy between physicians' practice and their preferences for themselves underscores the personal and professional dilemmas related to these issues, which are faced daily by many physicians, and impede their compassionate behavior toward patients. Increasing the awareness of physicians of such discrepancies, and providing them with appropriate behavioral tools, including communication skills, is a timely need which should be addressed by the medical profession, medical services and medical schools.
