Factors influencing dialysis patients' completion of advance directives

Although chronic dialysis patients support the use of advance directives, they rarely complete them. We asked 80 chronic dialysis patients (60 receiving in-center hemodialysis and 20 receiving peritoneal dialysis) why they had not completed an advance directive, and gave them the opportunity to complete a dialysis-specific living will and to designate a health care proxy. Questionnaires containing the dialysis-specific living will, patient demographic information, and questions about advance directives were distributed during a routine hemodialysis session or peritoneal dialysis clinic visit by a nurse working in the unit. Forty-one hemodialysis patients and 14 peritoneal dialysis patients completed the questionnaires (69% response rate). The mean age was 53 +/- 15 years and the mean time on dialysis was 5 +/- 5 years. Fifty-eight percent of the patients were women, 57% were white, 67% were hospitalized in the past year, 23% were employed, 70% had children, and 21% lived alone (43% lived with a partner and 11% lived with parents). All patients thought advance directives were a good idea, but only 35% had completed one and only seven (14%) had discussed wishes for life-sustaining therapy with their nephrologist; 34 patients (67%) had discussed their wishes with their family, Most said they had not completed an advance directive because their family knew what they would want (12 of 32 patients [38%]). Thirty-nine patients who completed the questionnaire also completed the dialysis-specific living will (71%). Those who did not complete the dialysis-specific living will chose not to because they were not sure what they would want done (12 of 16 patients [75%]). The only demographic factor that influenced completion of the dialysis-specific living will was having children: more patients with children did not complete the will (12 of 37 patients [32%] with children v two of 16 patients [13%] without children; P = 0.02). The dialysis-specific living will asks about choices for life-sustaining treatment (cardiopulmonary resuscitation and dialysis) based on one's health state (current health; permanent coma; terminal illness; mild, moderate, or severe stroke; dementia), Using patient-specific advance directives that focus on health states rather than life-sustaining interventions leg, the dialysis-specific living will) and repeated discussion of advance directives and advance care planning initiated by dialysis unit staff may improve the completion of advance directives by chronic dialysis patients, The appropriate focus of such issues should include family involvement and health states rather than treatment interventions, (C) 1997 by the National Kidney Foundation, Inc.
