An empirical study of withdrawal of life supporting treatment. However, there are still some limitations to our study, as follows. These findings were also essentially consistent across various subgroup analyses according to selected confounders, as well as in the analyses that limited dementia diagnoses made by neurologists or psychologists. Experience with not offering dialysis to patients with a poor prognosis. Variation in the attitudes of dialysis unit medical directors toward decision to withhold and withdraw dialysis. Dialysis patients’ preferences regarding cardiopulmonary resuscitation and withdrawal of dialysis in Japan. Institutional Review Board of the National Cheng Kung University Hospital (A-ER-101-089). Kalirao P, Pederson S, Foley RN, Kolste A, Tupper D, Zaun D, Buot V, Murray AM. Alzheimer's Research & Therapy Continuous variables were compared by Student’s t test, and comparisons of difference between categorical variables were analyzed by the chi-square test or Fisher exact test. Sehgal AR, Grey SF, DeOreo PB, Whitehouse PJ. 2009;19(3):500–8. Patient refusal is taken into account when a physician refuses initiating haemodialysis, but it is tempered by a second opinion, or by the desire of the doctor to oppose this ‘reticence’. Flow chart of the establishment of end-stage renal disease (ESRD) and non-ESRD populations. To the best of our knowledge, this is the first study to quantify the role of ESRD in investigating the etiology and cumulative risk of dementia. Clinical practice guideline on shared decision-making in the appropriate initiation of and withdrawal from dialysis. Yang WC, Hwang SJ, Taiwan Society of N. Incidence, prevalence and mortality trends of dialysis end-stage renal disease in Taiwan from 1990 to 2001: the impact of national health insurance. Meanwhile, the effect of competing risk of mortality should be taken into consideration when performing epidemiologic analyses among populations with high risk of mortality. The Poisson assumption was used to estimate age- and sex-specific IRs, and the corresponding 95% confidence intervals (CIs) were estimated by the exact method. The findings of our study might facilitate better decision-making in healthcare policies and may spur the development of more effective screening and therapeutic strategies for reducing the burden of dementia in the ESRD population. The population of active nephrologists in the region can be characterized by their age, sex and number of years practicing haemodialysis. We further investigated the effect of ESRD on the cause-specific or subdistribution hazards for dementia within the subgroups stratified by various age, sex, and selected comorbidities (Fig. 3 and Additional file 1: Figure S2), and the analyses still revealed the consistent results. Wing AJ. McLean AM. Am J Kidney Dis. If such disruptive patient responses are not sufficiently abated by appropriate normal measures, then discontinuing haemodialysis may be proposed. Moreover, the follow-up period is more than one decade, which is more than enough to assess the association between morbidities and incident dementia. It's generally agreed upon that patients might consider stopping dialysis if: 2  The patient also has an acute illness that will cause a great deal of … Also, discomfort during haemodialysis and, for a minority of practitioners (three out of 17), refusal by the patient to continue dialysis, and deterioration in the patient's quality of life were the basis for these decisions to discontinue treatment. Consequently, such issues are not dealt with at the beginning of treatment. Until 1980 in Great Britain very few patients over the age of 60 commenced haemodialysis treatment [10]. Am J Kidney Dis. Renoprotective effect of renin-angiotensin-aldosterone system blockade in patients with predialysis advanced chronic kidney disease, hypertension, and anemia. Each of the nephrologists interviewed had at some time or another decided to discontinue haemodialysis of elderly patients; nine of them stated that they had discontinued haemodialysis on more than 10 occasions each. 2005;46(1):200–4. Cumulative incidence rates of dementia and all-cause mortality estimated by the cumulative incidence competing risk analysis between patients with and without end-stage renal disease (ESRD). Murray AM, Tupper DE, Knopman DS, Gilbertson DT, Pederson SL, Li S, Smith GE, Hochhalter AK, Collins AJ, Kane RL. O'Rourke MF, Safar ME. J Epidemiol. This freedom is respected by young nephrologists, but the most senior nephrologists express greater resistance to and resentment of such freedom of choice. Procedural and clinical practice guidelines and general principles for withdrawing dialysis are published in UK [17], USA [18] and Canada [10]. 2011;58(2):228–34. The results from the multivariable cause-specific competing risk analyses comparing the risk of dementia between ESRD and non-ESRD individuals revealed that ESRD was one of the etiological factors for developing dementia (cause-specific HR (csHR) : 2.06, 95% CI [1.95–2.17]) (Table 3). By contrast, continuing social interaction, even against the background of a disease with a highly uncertain or terminal prognosis, would mean that the patient could still continue to benefit from the treatment. In the case of elderly patients, either of sound mind or with cognitive disorders, how do nephrologists react to requests to discontinue or to refusals of haemodialysis? Patients are free to choose whether or not to come. You may feel that dialysis is no longer maintaining or improving your quality of life. In the US, 20% of renal dialysis candidates chose to forego haemodialysis. http://www.who.int/mental_health/neurology/dementia/dementia_thematicbrief_epidemiology.pdf, https://www.mohw.gov.tw/cp-137-522-2.html, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/, https://doi.org/10.1186/s13195-019-0486-z. 2007;50(2):270–8. Individually, the practitioners were requested not to provide information about their qualifications or status prior to the interview, or about the nature and duration of their professional experience with dialysis. This material was prepared by the Southern California Renal Disease Council, Inc. under contract #HHSM-500-2006- Kurella Tamura M, Covinsky KE, Chertow GM, Yaffe K, Landefeld CS, McCulloch CE. The nephrologists interviewed were of the opinion that physical and psychological deterioration (Table 6) were the principal criteria motivating their decision. The principal reasons for discontinuation were physical and mental deterioration and, to a lesser extent, somatic complications (five out of 17 practitioners) and the development of intercurrent illnesses (two out of 17). Individuals were defined as having dementia if the diagnosis was recorded once or more at inpatient care or twice or more at ambulatory care with a minimum interval of > 30 days within 1 year. This will rapidly lead to an increase in problems related to the acceptance or rejection of requests to carry out or discontinue haemodialysis treatment in the elderly. The NHI is a nationwide healthcare program, which was instituted in 1995 and covered 99.9% of the residents as of 2014 [23]. None of the nephrologists interviewed requested the patient's consent before each haemodialysis session. Dementia in patients undergoing long-term dialysis has not been clearly defined; however, four different entities have been described. Please check for further notifications by email. Part of The nephrologists interviewed stated that, from among the factors involved, severe dementia (15 out of 17 nephrologists), severe and irreversible neurological sequelae of stroke (14 out of 17) and, paradoxically, refusal by the patient (11 out of 17) would be foremost among the factors governing their decision to discontinue haemodialysis (Table 7). [ncbi.nlm.nih.gov] Others chapters discuss a philosophical and religious analysis of stopping treatment and the clinical and ethical aspects of stopping treatment in dialysis. As clinicians we also may be uncomfortable taking away medications, as we are trained to always “do” something. Withdrawal from dialysis for patients with end-stage renal disease (ESRD) results in death within a few days. Stopping chronic dialysis. It is, therefore, a decision with the most serious consequences. Other illnesses were then focused upon by Brocker as factors potentially rendering renal dialysis futile: cancer, AIDS, terminal heart failure, pulmonary pathologies, peripheral vascular disease and incurable neurological diseases, such as Alzheimer's. For the practitioners studied, cognitive disorders were the principal conditions leading to discontinuation of haemodialysis. The comorbidities listed in the Additional file 1: Table S2 were identified and considered to reduce potential confounding for risk estimation of dementia. Though it’s a natural part of the progression of the disease, there are several things you can do to try and halt its progress and help your loved one enjoy mealtimes and stay healthy for as long as possible. Irreversible neurological sequelae of stroke would influence 64% of nephrologists to take the same position. The management of uraemia in the elderly: treatment choices. Hospice is a very good option in many cases. Our study results clearly suggested that ESRD was indeed one of the etiological factors for overall or various subtypes of dementia because of its increased cause-specific relative hazards for dementia (csHRs 2.01–2.71) (Table 3). Dementia is prevalent in the end-stage renal disease (ESRD) population. Table 1 summarizes the differences in the demographic data between the ESRD and non-ESRD groups. PubMed  J Electromyogr Kinesiol. Finally, the practitioners were asked if they had obtained the patient's consent before each dialysis session. Birmelé B, François M, Pengloan J et al. Of that cohort, 80% would want to continue dialysis if they were demented and 45% if they had terminal cancer. Dialysis encephalopathy syndrome, the result of acute intoxication of aluminium caused by the use of an aluminium-containing dialysate, was a common occurrence prior to 1980. Medical factors governing discontinuation of haemodialysis, Non-medical factors governing discontinuation of haemodialysis, Factors liable to influence the discontinuation of haemodialysis in the elderly. The prescriptions for medications are also closely correlated with some specific illnesses; for example, the use of statin is associated with hypercholesterolemia. All nephrologists continue caring for patients with ESRD irrespective of the patients’ position with regard to dialysis. This study has shown that exercising the right to decide to refuse or discontinue haemodialysis is a practice accepted by the vast majority of nephrologists in one region of France. A second consultation with a colleague might favour the development of greater trust, and enable the wishes of the patient to be understood more fully. 2002;13:628a. A study was performed in Japan to elicit the preferences of patients on haemodialysis with regard to the continuation of the dialysis if they were severely demented or had terminal cancer [21]. 2016;15(8):857–68. The difference in IRs between the ESRD and non-ESRD groups was still remarkable even after stratification by sex and age, except for those under 18 years. Ann Stat. Your comment will be reviewed and published at the journal's discretion. The relative hazard estimated from cause-specific models may be better suited for studying the etiology of diseases, whereas that derived from subdistribution models has been used to predict an individual’s risk or allocating resources [32, 33]. ESRD was still associated with inverse relationships between cause-specific hazards and subdistribution hazards for either overall or any subtype of dementia (Additional file 1: Table S4). https://doi.org/10.1186/s13195-019-0486-z, DOI: https://doi.org/10.1186/s13195-019-0486-z. Tilki HE, Akpolat T, Coskun M, Stalberg E. Clinical and electrophysiologic findings in dialysis patients. In 1997, 25 000 patients in France were on dialysis, 90% of them on haemodialysis. The only exclusion criterion, attendance at a group interview, was applied retrospectively. Furthermore, the opposite direction of csHRs (> 1) and sdHRs (< 1) for the association between ESRD and risk of dementia noted in our study could happen if both the effect of cause-specific hazard ratios associated with all-cause mortality is strong enough and the baseline cause-specific hazard rate for all-cause mortality is of great magnitude [32], as shown in Table 3 and Additional file 1: Table S4.
