A Patient-Centered Vision of Care for ESRD: Dialysis as a Bridging Treatment or as a Final Destination?

The ESRD population is heterogeneous, including patients without severe comorbidity for whom dialysis is a bridge to transplantation or a long-term maintenance treatment, as well as patients with a limited life expectancy as a result of advanced age or severe comorbidity for whom dialysis will be the final treatment destination. The complex medical and social context of this latter group fits poorly in the homogeneous, disease-centered, and process-driven approach of many clinical practice guidelines for dialysis. In this commentary, we argue that the standards of treatment allocated to each individual patient should be defined not merely by his or her disease state, but also by his or her preferences and prognosis. In this more patient-centered approach, three attainable treatment goals with a corresponding therapeutic approach could be defined: (1) dialysis as bridging or long-term maintenance treatment, (2) dialysis as final treatment destination, and (3) active medical management without dialysis. For patients with a better overall prognosis, this approach will emphasize complication prevention and long-term survival. For patients with a limited overall prognosis, strictly disease-centered interventions often impose a treatment burden that does not translate into a proportional improvement in quantity or quality of life. For these patients, a patient-centered approach will place more emphasis on palliative management strategies that are less disease specific.     

Sleep Quality and Depression in Peritoneal Dialysis Patients

Background. Sleep quality (SQ) is a significant problem in peritoneal dialysis (PD) patients, yet the underlying factors are not well known. In addition, depression and impaired quality of life (QOL) are main problems in PD patients. We measured the SQ and investigated the effect of depression, QOL, and some other factors on SQ in PD patients. Methods. Data were collected from 124 PD patients (59 male, 65 female) in our center. Demographic data and laboratory values were analyzed. All patients were asked to complete the Pittsburgh Sleep Quality Index (PSQI), Beck Depression Index (BDI), and SF-36. Results. Mean age of the patients was 52.6 ± 14.3 year. The prevalence of poor SQ was 43.5%, defined as global PSQI score >5. The prevalence of depression was 25.8%, defined as BDI scores >17. The poor sleepers had higher BDI scores, poor QOL, older age, and lower duration of PD compared to the good sleepers. There was not a difference in hemoglobin, albumin, C-reactive protein, Kt/V, urea, creatinine, lipid parameters, gender, marital status, cigarette smoking, mode of PD, and comorbidity between poor and good sleepers. The global PSQI score was correlated negatively with both PCS and MCS (r?=??0.414, r?=??0.392, respectively; p < 0.001) and correlated positively with BDI scores and age (r?=?0.422, p < 0.001 and r?=?0.213, p = 0.018, respectively). In multivariate analysis, only BDI scores were found to be factors that could predict the patients being poor sleepers. Conclusion. Poor SQ is a significant problem in PD patients, and we found an association with depression, QOL, and age. Regular assessment and management of SQ may be important especially with PD patients who are depressive and elderly to increase QOL.     

Symptom clusters in incident dialysis patients: associations with clinical variables and quality of life

Background. To date, the pathophysiology underlying symptomsin renal patients is still unclear. Symptom management researchsuggests that identification of related clusters of symptomscould provide insight into underlying determinants associatedwith multiple symptom experience. Theoretically, symptoms withina cluster could have a synergistic relationship. We aimed toidentify symptom clusters in incident dialysis patients, andinvestigated associations between symptom clusters, clinicalvariables, functional status as measured by the Karnofsky Indexand quality of life. Methods. 1553 haemodialysis (HD) and peritoneal dialysis (PD)patients completed the Kidney Disease Quality of Life ShortForm symptom/problem list at 3 months after the start of dialysis.Principal component analysis using varimax rotation was usedto identify symptom clusters. Results. Patients were bothered by an average of 2.8 (±2.4)symptoms of ‘moderate bother’ or more. Three clusterswere identified, explaining 49% of the total variance. All clustersshowed strong negative associations with the SF-36 quality oflife dimensions (–0.142 to –0.593) and with functionalstatus (–0.130 to –0.332) in HD and PD patients.In contrast, only the clinical variables serum albumin (–0.084to –0.232) and haemoglobin (–0.068 to –0.126)were associated with all clusters in HD patients, and Kt/V_urea(–0.089 to –0.125) in PD patients. Conclusions. Symptom clustering does not explain the lack ofmeaningful associations between symptoms and clinical variables.Strong associations of symptom clusters with quality of lifedimensions suggest that psychological factors could better explainsymptom burden. Patients’ perceptions of symptoms shouldbe routinely assessed as part of clinical care to improve self-managementstrategies.     

Malnutrition in the Elderly Patient on Dialysis

Approximately one-third of all dialysis patients have mild to moderate malnutrition, while 6–8% have severe malnutrition, which is associated with increased morbidity and mortality rates and numerous pre-existing factors directly correlated with, or existing prior to, replacement hemodialysis. However, moderate to severe malnutrition (present in 10–30% of dialysis patients) is a prevalent cause of death among the elderly. Many of these patients have a particularly unstable cardiovascular and metabolic status that, independent of any underlying uremia and/or dialysis, impacts negatively on both their quality of life and clinical status. Moreover, their condition is often further exacerbated by dialysis itself, with its acute (e.g., hypotension and sensorial alterations) and chronic complications, including an exacerbation of malnutrition and systemic vascular disease. Malnutrition can occur secondary not only to erroneous dietary choices or uremia, but it may also depend on the patient's level of tolerance to dialysis and on the dialysis modality. Despite the improvements made to dialysis techniques, the nutritional condition of elderly patients on dialysis for chronic renal failure remains a cause for concern. In this patient category, it is therefore mandatory to ensure the daily supervision of nutritional status and early control when the first signs of malnutrition appear.     

Maintenance Dialysis throughout the World in Years 1990 and 2010

Rapidly rising global rates of chronic diseases portend a consequent rise in ESRD. Despite this, kidney disease is not included in the list of noncommunicable diseases (NCDs) targeted by the United Nations for 25% reduction by year 2025. In an effort to accurately report the trajectory and pattern of global growth of maintenance dialysis, we present the change in prevalence and incidence from 1990 to 2010. Data were extracted from the Global Burden of Disease 2010 epidemiologic database. The results are on the basis of an analysis of data from worldwide national and regional renal disease registries and detailed systematic literature review for years 1980–2010. Incidence and prevalence estimates of provision of maintenance dialysis from this database were updated using a negative binomial Bayesian meta-regression tool for 187 countries. Results indicate substantial growth in utilization of maintenance dialysis in almost all world regions. Changes in population structure, changes in aging, and the worldwide increase in diabetes mellitus and hypertension explain a significant portion, but not all, of the increase because increased dialysis provision also accounts for a portion of the rise. These findings argue for the importance of inclusion of kidney disease among NCD targets for reducing premature death throughout the world.     

Decisions concerning potentially life-sustaining treatments in paediatric nephrology: a multicentre study in French-speaking countries.

BACKGROUND: Few studies have looked at how decisions are made to withhold or to withdraw potentially life-sustaining treatments (LST) in paediatric nephrology. The aim of this work was to evaluate such practices in all nephrology centres in French-speaking European countries, so that guidelines could be discussed and drawn up by professionals. METHODS: We used semi-directed interviews to question health care professionals prospectively. We also retrospectively analysed the medical files of all children (n = 50) for whom a decision to withhold or to withdraw LST had been made in the last 5 years. The doctors (n = 31) who had been involved in the decision-making process were interviewed. RESULTS: All 31 of the French-speaking paediatric nephrology centres in Europe were included in this study. Of these, 18 had made decisions in the previous 5 years about withholding or withdrawing LST. Resultant quality of life, based on long-term living conditions, was the principal criterion used to make the decisions. Relational aspects of life and the child's prognosis were also considered. The decision-making processes were not always collective, even though interactions between doctors and the rest of the medical team seemed to be key elements to them. The parents' involvement in the decision-making process differed between centres. CONCLUSIONS: The criteria used to decide whether to withhold or to withdraw LST are not standardized, and no specific guidelines exist.     

Decision making concerning life-sustaining treatment in paediatric nephrology: professionals' experiences and values.

BACKGROUND: In a previous article, we studied decisions to withhold or withdraw life-sustaining treatment (LST) taken between 1995 and 2001 in 31 French-speaking paediatric nephrology centres. Files were available for 18 of the 31 centres. A grid was used to analyse the criteria on which decisions were based, and the results were enriched by an analysis of interviews with the doctors at these centres (31 interviews with doctors from the 18 centres). The goal was to describe in detail and to specify the criteria on which decisions to withhold or withdraw LST were based, in cases extracted from the files. The second paper deals exclusively with the interviews with doctors and analyses their lifetime's experience and perception. METHODS: We carried out semi-directed interviews with nephrologists from all the paediatric nephrology centres in France and the French-speaking regions of Switzerland and Belgium. RESULTS: We interviewed 46 paediatric nephrologists. Most were aware that decisions relating to LST are necessary and based on the assessment of the child's quality of life. According to them, decisions are not based on scientific criteria, but on the capacity to accept handicap, the family's past experiences and the doctor's own projections. They report that their task is particularly difficult when their action may contribute to death (withdrawal of treatment or acceleration of the process). They feel that their duty is to help the families in the acceptance of the doctors' decision rather than to encourage their participation in the decision-making process (DMP). CONCLUSIONS: This article shows that paediatric nephrologists differ in their opinions, mostly due to their own ethical convictions. This observation highlights the need to establish common rules taking into account the views held by doctors. This is the only way to establish an ethical code shared by professionals.

Dialysis/Hemofiltration in Schizophrenia: A Journey by Night and Cloud

Hypotheses for the etiology of schizophrenia are discussed and related to possible treatments utilizing artificial kidney systems. For hemofiltration particularly, a theoretical framework is presented for treatment planning. Emphasis is placed on the necessity of using rigid diagnostic criteria for patient selection. Results are reported on two "strict" schizophrenic patients after a series of hemofiltration treatments. One patient showed no clinical improvement after seventeen treatments and died subsequently in a mountaineering accident. Though clinical improvement was noted in the second patient (22 treatments in four months), it is unjustifiable to attribute this solely to hemofiltration. Increased family and medical staff attention towards the patient is sufficient explanation for all changes noted in the patient's symptomatology. Chemical analyses so far have failed to detect any endorphins, normal or abnormal, in the hemofiltrates of either the two patients or two normal controls (sensitivity 30 pmol/L).

Health related quality of life (HRQOL) of kidney transplanted patients: variables that influence it

The incidence and prevalence of patients on renal replacement therapy (RRT) who receive a renal transplant are continuously increasing in Spain. At the moment, they are the main group of end-stage renal disease (ESRD) patients in our region (60% of total RRT patients). The aim of the present study was to assess the health related quality of life (HRQOL) of kidney transplanted patients of our region, and to identify socio-demographic and clinical variables that influence it. The intention was also to compare the HRQOL of these patients with that of chronic haemodialysis (HD) patients and of the general population. METHODS: Two hundred and ten kidney transplanted patients and 170 HD patients were evaluated using the Karnofsky performance scale (KPS), sickness impact profile (SIP), and SF-36 Health Survey (SF-36). Socio-demographic and clinical data, including a comorbidity index (CI), were also collected. To compare our patients with the general population we used SF-36 mean scores from an aleatory sample taken from our region. RESULTS: Transplant patients had lower mean scores on SIP dimensions and higher scores on SF-36 dimensions than chronic HD patients. In transplant patients, we found significant differences on SIP and SF-36 scores in gender, educational level, haematocrite and haemoglobin, CI, time since transplantation, and KPS. CONCLUSIONS: The HRQOL of transplant patients is clearly better than that of chronic HD patients and similar to that of the general population. Differences in the HRQOL within transplant patients did not appear to be as a result of patient's age, but rather it would appear to be a consequence of gender, analytic figures, CI, KPS score, time with transplant, and educational level.     

Health-Related Quality of Life and Dialysis Dependence in Critically Ill Patient Survivors of Acute Kidney Injury

Background: Acute kidney injury is a common disorder in critical ill patients and it is associated with high mortality. Few studies focus on long-term perspectives such as health-related quality of life (HRQOL) and dialysis dependence. Methods: Prospective cohort study at the intensive care unit (ICU) of a Brazilian tertiary hospital. All patients requiring dialysis over a 2-year enrollment period were included. The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) assessed the HRQOL along with patient status and dialysis dependence. Results: 408 patients (11%) required dialysis. ICU, hospital, and after-hospital cumulative fatality rates were 70%, 74%, and 80%, respectively. A total of 68 of 82 eligible patients were interviewed in an average of 256 days after hospital discharge, while 8 patients (11.8%) were in regular dialysis. There was no association between Acute Physiology and Chronic Health Evaluation II score, use of vasopressors, mechanical ventilation, creatinine, number of dialysis, and SF-36 scores. Better HRQOL was associated with previous conditions, as younger age and no chronic kidney disease; condition related to severity of acute illness, as have not had sepsis, short period at ICU, and hospital; and conditions after discharge, considered working currently. Conclusions: Previous chronic kidney disease was strongly associated with permanence in dialysis and lower further HRQOL. Younger survivors who have not had sepsis or long stays at hospitals, able to return to their jobs, had better HRQOL.
