Death by withdrawal from dialysis: a 20-year clinical experience.
The reasons for withdrawal from dialysis are not well understood. The goals of this study were to determine the risk of dying by withdrawal from dialysis over time and to elucidate pertinent clinical correlates in 716 long-term dialysis patients. These patients were monitored from the initiation of dialysis through the time of death, transplant or transfer to another program during a 20-yr period from 1970 through 1989. The causes of death in the 340 deceased patients were analyzed. Clinical correlates and associated risk factors were evaluated in the patients who died from withdrawal from dialysis. Withdrawal from dialysis was defined as: "Death with manifestations of uremia because of withdrawal from dialysis. Underlying medical conditions should not have been active, leading to rapid deterioration with imminent death." Withdrawal from dialysis and cardiac events were the second leading cause of death, each accounting for 18.5% of the deaths. Patients stopping dialysis were older at the start of dialysis than were patients dying of other causes (P < 0.0006; Kruskal-Wallis test), with 65.1% of these patients 61 yr of age and older. Cancer, malnutrition, catabolism, and "dissatisfaction with life" were important associations with the decision to withdraw. More than 50% of patients withdrawing from dialysis had either diabetic nephropathy or atherosclerotic renal vascular disease. Withdrawal from dialysis was a common cause of death in these dialysis patients especially if they were over 61 and had systemic diseases such as diabetes mellitus and renal vascular disease. The reasons for a higher incidence of withdrawal in certain programs deserve further study.
