Dialysis patients' preferences regarding cardiopulmonary resuscitation and withdrawal of dialysis in Japan

The aim of this study is to show the preferences of Japanese dialysis patients for receiving cardiopulmonary resuscitation (CPR) in their current health status, if they were severely demented, or if they had terminal cancer and to determine their desires about continuing dialysis if they were severely demented or had terminal cancer. A questionnaire survey including the three scenarios was administered to 450 dialysis patients in 15 hospitals in Japan. Three hundred ninety-eight patients completed the questionnaires for a response rate of 88%. The majority of responding patients were men and were undergoing hemodialysis. Only 5% of the patients had discussed their preferences regarding CPR with their physicians, and 29%, with their family members. Forty-two percent of the patients answered that they would want to receive CPR if they experienced cardiopulmonary arrest in their current health status, and 12% answered in the affirmative if they were seriously demented or had terminal cancer. Eighteen percent of the patients would want to continue dialysis if they were demented, and 45%, if they had terminal cancer. Statistical analysis showed that more patients who were working tended to want to continue dialysis if they had terminal cancer than those who were not (53% versus 37%; P < 0.014). Patients' age and preferences did not statistically correlate. Preferences of Japanese dialysis patients for CPR and dialysis vary according to differences in health status, and only a minority would want to receive CPR for cardiopulmonary arrest even in their current health status.
