Factors Associated With Discontinuation of Home Hemodialysis.

ABSTRACT: Home hemodialysis (HHD) is associated with improved clinical and quality-of-life outcomes compared to in-center hemodialysis, but remains an underused modality in the United States. Discontinuation from HHD therapy may be an important contributor to the low use of this modality. This study aimed to describe the rate and timing of HHD therapy discontinuation, or technique failure, and identify contributing factors.Retrospective cohort study.Using data from a large dialysis provider, we identified a nationally representative cohort of patients who initiated HHD therapy from 2007 to 2009 (N=2,840).Demographics, end-stage renal disease duration, kidney transplant listing status, comorbid conditions, level of urbanization or rurality based on residence zip code, socioeconomic status based on residence zip code, and dialysis facility factors.Discontinuation from HHD therapy, defined as 60 or more days with no HHD treatments.Competing-risk models were used to produce cumulative incidence plots and identify sociodemographic and clinical variables associated with HHD therapy discontinuation. Transplantation and death were treated as competing risks for HHD therapy discontinuation.The 1-year incidence of discontinuation was 24.9%, and the 1-year mortality estimate was 7.6%. Median end-stage renal disease duration prior to initiating HHD therapy was 2.1 years. Diabetes and smoking/alcohol/drug use were associated with increased risk for HHD discontinuation (HRs of 1.34 [95% CI, 1.07-1.68] and 1.34 [95% CI, 1.01-1.78], respectively). Listing for kidney transplantation and rural residence (rural-urban commuting area ? 7) were associated with decreased risk for HHD therapy discontinuation (HRs of 0.73 [95% CI, 0.61-0.87] and 0.78 [95% CI, 0.59-1.02], respectively).Limited to variables available within the DaVita dialysis and US Renal Data System data sets.A substantial proportion of patients discontinue HHD therapy within the first 12 months of use of the modality. Patients with diabetes, substance use, nonlisting for kidney transplantation, and urban residence are at greater risk for discontinuation. Targeting high-risk patients for increased support from clinical teams is a potential strategy for reducing HHD therapy discontinuation and increasing technique survival.

Project description:Background and objectivesThe last 15 years has seen growth in home hemodialysis (HD) utilization in Canada owing to reports of improved outcomes relative to patients on conventional in-center HD. What effect growth has had on home HD technique and patient survival during this period is not known.Design, settings, participants, & measurementsWe compared the risk of home HD technique failure, mortality, and the composite outcome among three incident cohorts of patients on home HD in Canada: 1996-2002, 2003-2007, and 2008-2012. A multivariable piece-wise exponential model was used to evaluate all outcomes using inverse probability of treatment and censoring weights.ResultsA total of 1869 incident patients on home HD were identified from the Canadian Organ Replacement Register. Relative to those treated between 2003 and 2007 (n=568), the risk of home HD technique failure was similar between patients treated between 1996 and 2002 (n=233; adjusted hazard ratio [AHR], 1.39; 95% confidence interval [95% CI], 0.78 to 2.46) but higher among incident patients on home HD treated between 2008 and 2012 (n=1068; AHR, 1.51; 95% CI, 1.06 to 2.15). Relative to patients treated between 2003 and 2007, adjusted mortality was similar among those treated between 2008 and 2012 (AHR, 0.83; 95% CI, 0.58 to 1.19) and those treated between 1996 and 2002 (AHR, 0.67; 95% CI, 0.38 to 1.21). The risk of the composite outcome of death and technique failure was similar across cohorts, as was the risk of receiving a kidney transplant. Increasing age, diabetes as a comorbidity, and smoking status were associated with an increased risk of death as well as the composite outcome. Medium-sized facilities had a lower risk of death, technique failure, and the composite outcome compared with larger facilities.ConclusionsA higher risk of technique failure was seen in the most contemporary era. Further characterization of the risk factors for, and causes of technique failure is needed to develop strategies to improve patient retention on home HD.

Project description:Hemodialysis is one of major stresses in patients' daily lives since there is no other path for life maintenance but to accept the machine and its' related rules.of this study was to explore factors associated with dependency on dialysis machine as reported by the patients.The sample of the study included 250 patients undergoing hemodialysis. For data collection a questionnaire specially designed for the needs of the research was used. More specifically, socio-demographic and clinical characteristics as well as several other self-reported variables were collected.Of the 250 participants, 53.2% was men while 65.2% was aged over 60 years. The study showed that 44% of the patients reported that their life depended very much on hemodialysis machine. Statistically significant association was observed between dependency on dialysis machine as reported by the patients and gender (p=0.030), education (p=0.022), job (p=0.001) and place of residence (p=0.001). Additionally, statistically significant association was observed between dependency on dialysis machine as reported by the patients and the degree of information about their problem (p=0.001) and whether patients reported adherence to treatment guidelines (p=0.001) or followed the proposed diet (p=0.001). Finally, statistically significant association was observed between dependency on dialysis machine as reported by the patients and relations with nursing staff (p=0.001), whether patients had noticed change in body image (p=0.001), whether they faced difficulties in social (p=0.001) and family environment (p=0.030), whether they hid their problem (p=0.006), whether they needed help in daily activities (p=0.001) and whether their lifestyle had changed (p=0.001).Socio-demographic and clinical characteristics as well as hemodialysis patients' beliefs are associated with machine dependency. This study contributed in outlining factors affecting dependency on dialysis machine, thus reinforcing multidisciplinary health care teams to develop interventions in order to address hemodialysis patients' needs.

Project description:ImportanceImmune suppression discontinuation is routinely attempted after allogeneic hematopoietic cell transplantation (HCT) and under current practices may lead to graft-vs-host disease (GVHD)-associated morbidity and death. However, the likelihood and predictive factors associated with successful immune suppression discontinuation after HCT are poorly understood.ObjectivesTo examine factors associated with successful immune suppression discontinuation and risk for immune suppression discontinuation failure under conventional HCT approaches and develop a practical tool to estimate successful immune suppression discontinuation likelihood at the clinical point of care.Design, setting, and participantsUsing long-term follow-up data from 2 national Blood and Marrow Transplant Clinical Trial Network studies (N = 827), a multistate model was developed to investigate the probability and variables associated with immune suppression discontinuation success. The study began in July 2015, and analyses were completed in August 2019.Main outcomes and measuresImmune suppression discontinuation and immune suppression discontinuation failure.ResultsOf the 827 patients included in the analysis, 456 were men (55.1%). Median age at transplant was 44 (range, <1-67) years. With median follow-up of 72 (range, 11-124) months, 20.0% of the patients were alive and not receiving immune suppression at 5 years. Older recipient age (adjusted odds ratio [aOR] of >50 vs <30 years, 0.27, 99% CI, 0.14-0.50; P < .001), mismatched unrelated donor (aOR, mismatched unrelated vs matched related, 0.37; 99% CI, 0.14-0.97; P = .008), peripheral blood graft (aOR of peripheral blood graft vs bone marrow, 0.46; 99% CI, 0.26-0.82; P < .001), and advanced stage disease (aOR of advanced vs early disease, 0.45; 99% CI, 0.23-0.86, P = 0.002), were significantly associated with decreased odds of immune suppression discontinuation. Failed attempts at immune suppression discontinuation (127 patients [37.1% of total immune suppression discontinuation events]) resulting in GVHD were significantly associated with use of peripheral blood stem cells (HR, 2.62; 99% CI, 1.30-5.29; P < .001), prior GVHD, and earlier immune suppression discontinuation attempts. Earlier immune suppression discontinuation was not associated with protection from cancer relapse after HCT (adjusted hazard ratio for discontinuation vs not, 1.95; 99% CI, 0.88-4.31; P = .03).Dynamic prediction models were developed to provide future immune suppression discontinuation probability according to individual patient characteristics.Conclusions and relevanceSuccessful immune suppression discontinuation is uncommon in the setting of peripheral blood stem cell grafts. The data suggest earlier attempts at ISD conferred no long-term benefit, given frequent ISD failure, limited subsequent success after initial failed ISD attempt, and no evidence of relapse reduction. Using a risk model-based clinical application, physicians may be able to identify individual patients' probability of successful immune suppression discontinuation.
