Proposal for the shared decision-making process regarding initiation and continuation of maintenance hemodialysis

The Gap in Attitudes Toward Withholding and Withdrawing Life-Sustaining Treatment Between Japanese Physicians and Citizens

BACKGROUND

According to some medical ethicists and professional guidelines, there is no ethical difference between withholding and withdrawing life-sustaining treatment. However, medical professionals do not always agree with this notion. Patients and their families may also not regard these decisions as equivalent. Perspectives on life-sustaining treatment potentially differ between cultures and countries. This study compares Japanese physicians' and citizens' attitudes toward hypothetical cases of withholding and withdrawing life-sustaining treatment.

METHODS

Ten vignette cases were developed. A web-based questionnaire was administered to 457 citizens and 284 physicians to determine whether they supported withholding or withdrawing treatment.

RESULTS

In a case where a patient had an advance directive refusing ventilation, 77% of the physicians and 68% of the citizens chose to withhold treatment. In a case where there was an advance directive but the patient's family requested treatment, 55% of the physicians and 45% of the citizens chose to withhold the ventilator. When a family requested withdrawal of the ventilator but patient wishes were unknown, 19% of the physicians and 48% of the citizens chose to withdraw the ventilator. However, when the patient had also indicated their wishes in writing, 49% of the physicians and 66% of the citizens chose to withdraw treatment. More physicians were prepared to withdraw dialysis (84%) and artificial nutrition (81%) at a patient's request than mechanical ventilation (49%).

CONCLUSIONS

A significant proportion of Japanese physicians and citizens were reluctant to withhold or withdraw life-sustaining treatment, even in cases where the patient had indicated their wishes in writing. They were more likely to withhold than withdraw treatment, and more likely to withdraw artificial nutrition than mechanical ventilation. Japanese physicians gave significant weight to family views about treatment but were less likely to agree to withdraw treatment than citizens, indicating a potential source of conflict in clinical settings.

Consensus-based proposal for forgoing dialysis therapy in Japan

The Japanese Society for Dialysis Therapy published a proposal in 2014 and revised it to Shared Decision Making for the Initiation and Continuation of Dialysis: A Proposal from the Japanese Society for Dialysis Therapy in 2020 to strictly adhere to guidelines of the Ministry of Health, Labour and Welfare, because forgoing life-sustaining treatment to respect the will of patients in end-of-life care is not stipulated by law in Japan. The revised proposal describes the process of providing information about renal replacement therapy, the natural course of end-stage kidney disease, and conservative kidney management (CKM), the conditions when providing CKM information to be considered by healthcare teams, the process of providing information about CKM if patients with decision-making capacity or families of patients without decision-making capacity wish to make the decision to forgo dialysis, the process of shared decision making for choosing CKM, and the importance of performing advance care planning (ACP) with patients and their families for making advance directives, etc. We need to promote ACP and to establish the content and practice of palliative care for patients after choosing CKM in collaboration with home-cased care doctors.

Changing landscape of dialysis withdrawal in patients with kidney failure: Implications for clinical practice

Dialysis withdrawal has become an accepted treatment option for patients with kidney failure and is one of the leading causes of death in patients receiving dialysis in high-income countries. Despite its increasing acceptance, dialysis withdrawal currently lacks a clear, consistent definition. The processes and outcomes of dialysis withdrawal have wide temporal and geographical variability, attributed to dialysis patient selection, influence from cultural, religious and spiritual beliefs, and availability of kidney replacement therapy and conservative kidney management. As a complex, evolving process, dialysis withdrawal poses an enormous challenge for clinicians and healthcare teams with various limitations precluding a peaceful and smooth transition between active dialysis and end-of-life care. In this review, we examine the current definitions of dialysis withdrawal, the temporal and geographical patterns of dialysis withdrawal, international barriers in the decision-making process (including dialysis withdrawal during the COVID-19 pandemic), and gaps in the current dialysis withdrawal recommendations for clinical consideration and future studies.

Perimortem changes in clinical parameters in patients undergoing maintenance hemodialysis

Background

End-of-life medical care for patients receiving maintenance hemodialysis (HD) therapy has become an increasingly important issue worldwide. Thus far, no clear indicators and/or biomarkers exist regarding the timing of HD therapy withdrawal.

Methods

To clarify the perimortem circumstances, we examined temporal changes in multiple clinical parameters during the last 10 serial HD sessions of 65 terminal patients with end-stage renal disease who had undergone maintenance HD and died in our hospital.

Results

The results showed that, while most of the laboratory data were unaltered, the physical parameters, such as systolic blood pressure and consciousness levels, gradually and significantly deteriorated toward the last HD session prior to death. The frequency of the use of vasopressors and O2 inhalation tended to increase. The accumulation of such severe conditions was observed at the last HD session. Of interest, the accumulation of severe conditions at the last HD session in patients with malignancies was significantly less than those with cardiovascular diseases or infectious diseases. The accumulation of severe conditions at the last HD session did not differ between patients who withdrew HD versus those who continued HD.

Conclusion

The results of the present study suggest that predicting the timing of maintenance HD therapy withdrawal is likely to be difficult and that the timing of maintenance HD therapy termination may differ among patient groups with distinct comorbid conditions.

Definition and Recommended Cultural Considerations for Advance Care Planning in Japan: A Systematic Review

Although Delphi studies in Western countries have provided a consensus for practices pertaining to advance care planning (ACP), their findings may not be applicable to Asian countries with distinct, family-oriented cultures. This systematic review aimed to synthesize the definitions of and evidence for ACP and analyze recommended practices in Japan. We conducted a systematic review using narrative synthesis in December 2018. Key words were searched from Ichushi-Web by NPO Japan Medical Abstracts Society, Citation Information by the National Institute of Informatics, and Japanese Institutional Repositories Online databases. In addition, in August 2019, we conducted hand searching using Google Scholar and Google. We included original Japanese articles that addressed factors regarding ACP (e.g. definitions, elements, roles and tasks, and timing of ACP). Data were synthesized using thematic analysis. The study protocol was registered prospectively (PROSPERO: CRD42020152391). Of the 3,512 studies screened, 27 were included: 22 quantitative and 5 qualitative. Five-position statements/guidelines were added by hand searching. Definitions and several distinct practice patterns of ACP and the importance of families' roles were identified. Unique recommendations addressed the importance of properly eliciting patients' preferences that are the best for both patients and families, engaging the public to raise awareness of ACP, and developing policies and guidelines for ACP. We identified the definition of and unique recommendations for ACP based on Japanese cultural values and norms. Further research is needed to evaluate the recommendations provided in this systematic review.

Palliative radiation treatment used for multiple purposes in a single irradiation field

In this case report, radiation therapy was performed for bilateral hydronephrosis developed during multiple bone metastases of breast cancer and ileus due to peritoneal dissemination. The patient's preirradiation creatinine level was 8.2 mg/dL, which decreased by the fourth day after starting irradiation therapy. Creatinine level ultimately decreased to 0.6 mg/dL. Pain due to lumbar spine metastasis alleviated and ileus was resolved, allowing the patient to live at home for approximately 5 weeks. The effect of radiotherapy for bilateral hydronephrosis and gastrointestinal obstruction was rapid and good. Palliative radiation treatment can be used for multiple purposes, and in the present patient, we were able to prolong the vital prognosis.

A descriptive analysis of end-of-life discussions for high-grade glioma patients

Background

End-of-life discussions (EOLDs) in patients with high-grade glioma (HGG) have not been well described. Therefore, this study examined the appropriateness of timing and the extent of patient involvement in EOLDs and their impact on HGG patients.

Methods

A cross-sectional survey was conducted among 105 bereaved families of HGG patients at a university hospital in Japan between July and August 2019. Fisher's exact test and the Wilcoxon rank-sum test were used to assess the association between patient participation in EOLDs and their outcomes.

Results

In total, 77 questionnaires were returned (response rate 73%), of which 20 respondents replied with refusal documents. Overall, 31/57 (54%) participated in EOLDs at least once in acute hospital settings, and a significant difference was observed between participating and nonparticipating groups in communicating the patient's wishes for EOL care to the family (48% vs 8%, P = .001). Moreover, >80% of respondents indicated that the initiation of EOLDs during the early diagnosis period with patients and families was appropriate. Most EOLDs were provided by neurosurgeons (96%), and other health care providers rarely participated. Additionally, patient goals and priorities were discussed in only 28% of the EOLDs. Patient participation in EOLDs was not associated with the quality of EOL care and a good death.

Conclusions

Although participation in EOLDs is relatively challenging for HGG patients, this study showed that participation in EOLDs may enable patients to express their wishes regarding EOL care. It is important to initiate EOLDs early on through an interdisciplinary team approach while respecting patient goals and priorities.

Nephrologists' Perspectives on Decision Making About Life-Sustaining Treatment and Palliative Care at End of Life: A Questionnaire Survey in Korea

Background: Nephrologists commonly engage in decision making regarding the withholding or withdrawal of dialysis and palliative care in patients at end of life (EoL). However, these issues remain an unsolved dilemma for nephrologists. Objective: To explore nephrologists' perceptions on the decision-making process about withholding or withdrawing dialysis and palliative care in Korea. Design: A nationwide 25-item questionnaire online survey via e-mail. Setting/Subjects: A total of 369 Korean nephrologists completed the survey. Results: The proportions of respondents who stated that withholding or withdrawing dialysis at EoL is ethically appropriate were 87.3% and 86.2%, respectively. A total of 72.4% respondents thought that withdrawal of dialysis in a maintenance dialysis patient is ethically appropriate. Responses regarding patient features that should be considered to withhold or withdraw dialysis were as follows: dialysis intolerance (84.3%), poor performance status (74.8%), patient's active request (47.2%), age (28.7%), very severe dementia (27.1%), and several comorbidities (16.5%). Among those nephrologists who responded to the question about the minimum age, at which dialysis should be withheld or withdrawn, most specified an age between 80 and 90 years (94.3%). Fifty-eight percent of respondents stated that terminally ill dialysis patients should be allowed to use palliative care facilities. In addition, a number of nephrologists thought that adequate palliative care facilities, specific treatment guidelines, enough time to manage patients, financial support, and adequate medical experts are necessary. Conclusions: Korean nephrologists thought that withholding or withdrawing dialysis at EoL is ethically appropriate, even in maintenance dialysis patients. Therefore, consensus guidelines for palliative care after withholding or withdrawal of dialysis are needed.

Physical Parameters, Use of Specific Medical Treatments, Nursing Levels, and Activities of Daily Living Are Potential Indicators for Forgoing Maintenance Hemodialysis

Maintenance hemodialysis (HD) therapy is essential for survival in patients with end-stage renal disease (ESRD); however, HD can also be life-threatening in the final stages of ESRD. Currently, no clear indicators and/or biomarkers exist regarding when HD should be forgone. In the present study, we examined temporal changes in multiple clinical parameters, including biochemical data, physical data, the use of specific medical treatments, nursing care levels, and the activities of daily living (ADL) in 47 ESRD patients who underwent maintenance HD and who died in our hospital. We also investigated the status of informed consents regarding the forgoing of HD in these patients. We found that while biochemical parameters were unaltered, physical parameters such as consciousness levels and blood pressure gradually deteriorated during hospitalization. The use of the following specific medical treatments significantly increased over time: vasopressor use, O₂ inhalation, and ventilator use. The need for nursing care increased and the ADL levels decreased toward the time of death. Medical doctors gave information regarding forgoing HD to patients and/or their family/relatives in 55% of cases, obtained agreement to forego HD in 45% of cases, and HD was actually foregone in 38% of cases. Most clinical parameters were not significantly different between the patients whose HD sessions were forgone versus those in whom HD was continued, indicating that HD was foregone in the very last stages of life. The results suggest that physical parameters, the use of specific medical treatments, the levels of nursing care, and ADL are potential indicators for forgoing HD in the final stages of ESRD.

Ethical Issues Around the Withdrawal of Dialysis Treatment in Japan

In Japan, terminating life-sustaining treatment (LST) in non-terminal patients is legally and ethically problematic given the lack of legal regulations regarding the termination of LST, including dialysis treatment. This article describes an ethically problematic case that happened at a hospital in Tokyo in March 2019, in which a patient died after a physician withdrew kidney dialysis upon the patient's request. Most national newspapers in Japan reported the case extensively and raised the question of ethical and legal permissibility of withdrawing dialysis treatment from non-terminal patients. In this article, we first examine the case within the current policy framework in Japan and then discuss how Japan can improve its end-of-life practice, focusing specifically on the patient's right to self-determination and treatment refusal. We recommend that policymakers consider legalizing the termination of LST and the patient's right to refuse treatment based on the principle of respect for autonomy.

Prediction model for cardiovascular events or all-cause mortality in incident dialysis patients

Some variables including age, comorbidity of diabetes, and so on at dialysis initiation are associated with patient prognosis. Cardiovascular (CV) events are a major cause of death, and adequate models that predict prognosis in dialysis patients are warranted. Therefore, we created models using some variables at dialysis initiation. We used a database of 1,520 consecutive dialysis patients (median age, 70 years; 492 women [32.4%]) from a multicenter prospective cohort study. We established the primary endpoint as a composite of the incidence of first CV events or all-cause death. A multivariable Cox proportional hazard regression model was used to construct a model. We considered a complex and a simple model. We used area under the receiver operating characteristic curve (AUROC) to assess and compare the predictive performances of the prediction models and evaluated the improvement in discrimination using the complex model versus the simple model using net reclassification improvement (NRI). We then assessed integrated discrimination improvement (IDI) to evaluate improvements in average sensitivity and specificity. Of 392 deaths, 152 were CV-related. Totally, 506 CV events occurred during the follow-up period (median 1,285 days). Finally, 692 patients reached the primary endpoint. Baseline data were set at dialysis initiation. AUROC for the primary endpoint was 0.737 (95% confidence interval [CI], 0.712–0.761) in the simple model and 0.765 (95% CI, 0.741–0.788) in the complex model. There were significant intergroup differences in NRI (0.44; 95% CI, 0.34–0.53; p < 0.001) and IDI (0.02; 95% CI, 0.02–0.03; p < 0.001). We prepared a Shiny R application for each model to automatically calculate the predicted occurrence probability (https://statacademy.shinyapps.io/App_inaguma_20190717/). The complex model made more accurate predictions than the simple model. However, the intergroup difference was not significant. Hence, the simple model was more useful than the complex model. The tool was useful in a real-world clinical setting because it required only routinely available variables. Moreover, we emphasized that the tool could predict the incidence of CV events or all-cause mortality for individual patients. In the future, we must confirm its external validity in other prospective cohorts.

Suboptimal initiation predicts short-term prognosis and vulnerability among very elderly patients who start haemodialysis

AIM

A recent, growing concern regarding haemodialysis in Japan is a sustained increase in the elderly population. Among very elderly people who start haemodialysis, the prognosis is considered to be poor; however, this has not been fully elucidated. This study aimed to discover the short-term prognosis and related factors in very elderly patients who commence haemodialysis.

METHODS

Between January 2008 and December 2013, 122 patients aged ≥85 years at haemodialysis initiation were documented in our hospital. Predictors of 90-day and 1-year mortality after haemodialysis initiation were assessed with Cox proportional hazards regression analysis. Selection of covariates for the multivariate model was based on forward stepwise selection using the probability of a likelihood ratio statistics.

RESULTS

The subjects' mean age was 87.4 ± 2.5 years, and 48% were female. The most common cause of death was infection (38% of patients) and the leading cause of infectious death was pneumonia. The 90-day and 1-year survival rates were 81% and 62%, respectively. Suboptimal initiation was a significant prognostic factor for 90-day [hazard ratio (HR) 3.98, 95% confidence interval (CI) 1.18-13.43] and 1-year [HR 3.19, 95% CI 1.51-6.76] mortality after adjusting for confounders in multivariate analysis.

CONCLUSION

Very elderly patients who started haemodialysis had a poor prognosis, and suboptimal initiation significantly predicted outcome. Shared decision-making with patients and their families is needed for initiating haemodialysis on the conditions that appropriate information on the expected prognosis is provided.

Longitudinal patterns of health-related quality of life and dialysis modality: a national cohort study

Background

Health-related quality of life (HrQoL) varies among dialysis patients. However, little is known about the association of dialysis modality with HrQoL over time. We describe longitudinal patterns of HrQoL among chronic dialysis patients by treatment modality.

Methods

National retrospective cohort study of adult patients who initiated in-center dialysis or a home modality (peritoneal or home hemodialysis) between 1/2013 and 6/2015. Patients remained on the same modality for the first 120 days of the first two years. HrQoL was assessed by the Kidney Disease and Quality of Life-36 (KDQOL) survey in the first 120 days of the first two years after dialysis initiation. Home modality patients were matched to in-center patients in a 1:5 fashion.

Results

In-center (n=4234) and home modality (n=880) patients had similar demographic and clinical characteristics. In-center dialysis patients had lower mean KDQOL scores across several domains compared to home modality patients. For patients who remained on the same modality, there was no change in HrQoL. However, there were trends towards clinically meaningful changes in several aspects of HrQoL for patients who switched modalities. Specifically, physical functioning decreased for patients who switched from home to in-center dialysis (p< 0.05).

Conclusions

Among a national cohort of chronic dialysis patients, there was a trend towards different patterns of HrQoL life that were only observed among patients who changed modality. Patients who switched from home to in-center modalities had significant lower physical functioning over time. Providers and patients should be mindful of HrQoL changes that may occur with dialysis modality change.

Factors Associated With Withdrawal From Maintenance Dialysis: A Case-Control Analysis

BACKGROUND

Little is known about differences in the clinical course between patients receiving maintenance dialysis who do and do not withdraw from dialysis therapy.

STUDY DESIGN

Case-control analysis.

SETTING & PARTICIPANTS

US patients with Medicare coverage who received maintenance hemodialysis for 1 year or longer in 2008 through 2011.

PREDICTORS

Comorbid conditions, hospitalizations, skilled nursing facility stays, and a morbidity score based on durable medical equipment claims.

OUTCOME

Withdrawal from dialysis therapy.

MEASUREMENTS

Rates of medical events, hospitalizations, skilled nursing facility stays, and a morbidity score.

RESULTS

The analysis included 18,367 (7.7%) patients who withdrew and 220,443 (92.3%) who did not. Patients who withdrew were older (mean age, 75.3±11.5 [SD] vs 66.2±14.1 years) and more likely to be women and of white race, and had higher comorbid condition burdens. The odds of withdrawal among women were 7% (95% CI, 4%-11%) higher than among men. Compared to age 65 to 74 years, age 85 years or older was associated with higher adjusted odds of withdrawal (adjusted OR, 1.61; 95% CI, 1.54-1.68), and age 18 to 44 years with lower adjusted odds (adjusted OR, 0.36; 95% CI, 0.32-0.40). Blacks, Asians, and Hispanics were less likely to withdraw than whites (adjusted ORs of 0.36 [95% CI, 0.35-0.38], 0.47 [95% CI, 0.42-0.53], and 0.46 [95% CI, 0.44-0.49], respectively). A higher durable medical equipment claims-based morbidity score was associated with withdrawal, even after adjustment for traditional comorbid conditions and hospitalization; compared to a score of 0 (lowest presumed morbidity), adjusted ORs of withdrawal were 3.48 (95% CI, 3.29-3.67) for a score of 3 to 4 and 12.10 (95% CI, 11.37-12.87) for a score ≥7. Rates of medical events and institutionalization tended to increase in the months preceding withdrawal, as did morbidity score.

LIMITATIONS

Results may not be generalizable beyond US Medicare patients; people who withdrew less than 1 year after dialysis therapy initiation were not studied.

CONCLUSIONS

Women, older patients, and those of white race were more likely to withdraw from dialysis therapy. The period before withdrawal was characterized by higher rates of medical events and higher levels of morbidity.

Treatment decisions for older adults with advanced chronic kidney disease

Dialysis initiation rates among older adults, aged 75 years or greater, are increasing at a faster rate than for younger age groups. Older adults with advanced CKD (eGFR < 30 ml/min/1.73 m2) typically lose renal function slowly, often suffer from significant comorbidity and thus may die from associated comorbidities before they require dialysis.A patient's pattern of renal function loss over time in relation to their underlying comorbidities can serve as a guide to the probability of a future dialysis requirement. Most who start dialysis, initiate treatment "early", at an estimated glomerulofiltration rate (eGFR) >10 ml/min/1.73 m2 and many initiate dialysis in hospital, often in association with an episode of acute renal failure. In the US older adults start dialysis at a mean e GFR of 12.6 ml/min/1.73 m2 and 20.6% die within six months of dialysis initiation. In both the acute in hospital and outpatient settings, many older adults appear to be initiating dialysis for non-specific, non-life threatening symptoms and clinical contexts. Observational data suggests that dialysis does not provide a survival benefit for older adults with poor mobility and high levels of comorbidity. To optimize the care of this population, early and repeat shared decision making conversations by health care providers, patients, and their families should consider the risks, burdens, and benefits of dialysis versus conservative management, as well as the patient specific symptoms and clinical situations that could justify dialysis initiation. The potential advantages and disadvantages of dialysis therapy should be considered in conjunction with each patient's unique goals and priorities.In conclusion, when considering the morbidity and quality of life impact associated with dialysis, many older adults may prefer to delay dialysis until there is a definitive indication or may opt for conservative management without dialysis. This approach can incorporate all CKD treatments other than dialysis, provide psychosocial and spiritual support and active symptom management and may also incorporate a palliative care approach with less medical monitoring of lab parameters and more focus on the use of drug therapies directed to relief of a patient's symptoms.

Factors affecting outcomes in patients reaching end-stage kidney disease worldwide: differences in access to renal replacement therapy, modality use, and haemodialysis practices

More than 2 million people worldwide are being treated for end-stage kidney disease (ESKD). This Series paper provides an overview of incidence, modality use (in-centre haemodialysis, home dialysis, or transplantation), and mortality for patients with ESKD based on national registry data. We also present data from an international cohort study to highlight differences in haemodialysis practices that affect survival and the experience of patients who rely on this therapy, which is both life-sustaining and profoundly disruptive to their quality of life. Data illustrate disparities in access to renal replacement therapy of any kind and in the use of transplantation or home dialysis, both of which are widely considered preferable to in-centre haemodialysis for many patients with ESKD in settings where infrastructure permits. For most patients with ESKD worldwide who are treated with in-centre haemodialysis, overall survival is poor, but longer in some Asian countries than elsewhere in the world, and longer in Europe than in the USA, although this gap has reduced. Commendable haemodialysis practice includes exceptionally high use of surgical vascular access in Japan and in some European countries, and the use of longer or more frequent dialysis sessions in some countries, allowing for more effective volume management. Mortality is especially high soon after ESKD onset, and improved preparation for ESKD is needed including alignment of decision making with the wishes of patients and families.
