Chronic kidney disease-associated pruritus: a comparison of instruments and associations with patient-reported outcomes using an electronic patient-reported outcome survey in Europe.

Background: The associations between self-reported chronic kidney disease-associated pruritus (CKD-aP) and patient-reported outcomes (PROs) have been reported using various instruments to assess itch. Data collection via multiple CKD-aP instruments allows the evaluation of different domains and measurements of CKD-aP burden and may help tailor data capture for future research or clinical care.

Methods: An electronic PRO (ePRO) survey was distributed to European hemodialysis (HD) patients enrolled in the Dialysis Outcomes and Practice Patterns Study (DOPPS) in 2021-23.

Preparing for responsive management versus preparing for renal dialysis in multimorbid older people with advanced chronic kidney disease (Prepare for Kidney Care): Study protocol for a randomised controlled trial.

Background: Chronic kidney disease (CKD) prevalence is steadily increasing, in part due to increased multimorbidity in our aging global population. When progression to kidney failure cannot be avoided, people need unbiased information to inform decisions about whether to start dialysis, if or when indicated, or continue with holistic person-centred care without dialysis (conservative kidney management). Comparisons suggest that while there may be some survival benefit from dialysis over conservative kidney management, in people aged 80 years and over, or with multiple health problems or frailty, this may be at the expense of quality of life, hospitalisations, symptom burden and preferred place of death.

Explaining International Trends in Mortality on Hemodialysis Through Changes in Hemodialysis Practices in the Dialysis Outcomes and Practice Patterns Study (DOPPS).

Rationale & Objective: Case-mix adjusted hemodialysis mortality has decreased since 1998. Many factors that influence mortality may have contributed to this trend, and these associations may differ by continental region. We studied changes in hemodialysis facility practices over time and their potential role in mediating changes in patient survival.

A stepped wedge cluster randomized trial of graphical surveillance of kidney function data to reduce late presentation for kidney replacement therapy.

Late presentation for kidney replacement therapy (KRT) is an important cause of avoidable morbidity and mortality. Here, we evaluated the effect of a complex intervention of graphical estimated glomerular filtration rate (eGFR) surveillance across 15% of the United Kingdom population on the rate of late presentation using data routinely collected by the United Kingdom Renal Registry. A stepped wedge cluster randomized trial was established across 19 sites with eGFR graphs generated from all routine blood tests (community and hospital) across the population served by each site.

European hemodialysis patient satisfaction with phosphate binders is associated with serum phosphorus levels: the Dialysis Outcomes and Practice Patterns Study.

Background: Hemodialysis (HD) patients are commonly prescribed phosphate binders (PBs) to manage serum phosphorus levels, as hyperphosphatemia is strongly associated with poorer survival. Nonadherence with the PB prescription is associated with elevated serum phosphorus levels. We studied associations between patient satisfaction with their PB and serum phosphorus levels and mortality rates.

Self-reported Pruritus and Clinical, Dialysis-Related, and Patient-Reported Outcomes in Hemodialysis Patients.

Rationale & Objective: Chronic kidney disease (CKD)-associated pruritus, generalized itching related to CKD, affects many aspects of hemodialysis patients' lives. However, information regarding the relationship between pruritus and several key outcomes in hemodialysis patients remains limited.

Study Design: Prospective cohort.

Reasons for Underreporting of Uremic Pruritus in People With Chronic Kidney Disease: A Qualitative Study.

Context: Uremic pruritus, or itch, is common in people with chronic kidney disease (CKD) and has a negative impact on their lives and well-being. However, for reasons currently unknown, itch often remains unreported and therefore untreated.

Objectives: To explore reasons for underreporting of itch to provide pointers for improving itch reporting and management in people with CKD.

Pruritus and Patient Reported Outcomes in Non-Dialysis CKD.

Background And Objectives: Among patients on hemodialysis, pruritus has been associated with poorer mental and physical quality of life, sleep quality, depression, and mortality. We evaluated patients with nondialysis CKD to describe the prevalence of pruritus, identify associated factors, and investigate associations with patient-reported outcomes.

Design, Setting, Participants, & Measurements: Using cross-sectional data from patient questionnaires in the CKD Outcomes and Practice Patterns Study (CKDopps), we asked patients with CKD stages 3-5 (nondialysis) from the United States, Brazil, and France to identify how much they were bothered by pruritus.

Associations between Hemodialysis Facility Practices to Manage Fluid Volume and Intradialytic Hypotension and Patient Outcomes.

Background And Objectives: Fluid overload and intradialytic hypotension are associated with cardiovascular events and mortality in patients on hemodialysis. We investigated associations between hemodialysis facility practices related to fluid volume and intradialytic hypotension and patient outcomes.

Design, Setting, Participants, & Measurements: Data were analyzed from 10,250 patients in 273 facilities across 12 countries, from phase 4 of the Dialysis Outcomes and Practice Patterns Study (DOPPS; 2009-2012).

Decision-making for people with dementia and advanced kidney disease: a secondary qualitative analysis of interviews from the Conservative Kidney Management Assessment of Practice Patterns Study.

Objective: To explore dialysis decision-making for adults who lack capacity due to cognitive impairment, a common and under-recognised condition in those with advanced chronic kidney disease (CKD).

Design: Secondary analysis of qualitative data collected during the Conservative Kidney Management Assessment of Practice Patterns Study programme of research was performed. Sixty semistructured interviews were conducted with multiprofessional team members from UK renal centres.

Greater fluid overload and lower interdialytic weight gain are independently associated with mortality in a large international hemodialysis population.

Background: Fluid overload and interdialytic weight gain (IDWG) are discrete components of the dynamic fluid balance in haemodialysis patients. We aimed to disentangle their relationship, and the prognostic importance of two clinically distinct, bioimpedance spectroscopy (BIS)-derived measures, pre-dialysis and post-dialysis fluid overload (FOpre and FOpost) versus IDWG.

Methods: We conducted a retrospective cohort study on 38 614 incident patients with one or more BIS measurement within 90 days of haemodialysis initiation (1 October 2010 through 28 February 2015).

New ways of working; delivering better care for people with long-term conditions.

Background: The cost-effectiveness of the traditional outpatient model for specialist care provision is increasingly being questioned in view of the changing patient needs, workforce challenges and technological advances.

Setting: This report summarises two RCGP London events showcasing new ways of delivering care for long-term conditions.

Questions: What are the alternative approaches to the traditional outpatient model and do they have common themes? What are the challenges and opportunities of these new models of care?

Methods: Presentation of examples of new ways of long-term condition care delivery and round-table facilitative discussion and reflection on the challenges and solutions around service re-design and implementation, the commissioning and funding of new models of care, the facilitation of system-wide learning and the collection of data for evaluation.

Mortality risk in patients on hemodiafiltration versus hemodialysis: a 'real-world' comparison from the DOPPS.

Background: With its convective component, hemodiafiltration (HDF) provides better middle molecule clearance compared with hemodialysis (HD) and is postulated to improve survival. A previous analysis of Dialysis Outcomes and Practice Patterns Study (DOPPS) data in 1998-2001 found lower mortality rates for high replacement fluid volume HDF versus HD. Randomized controlled trials have not shown uniform survival advantage for HDF; in secondary (non-randomized) analyses, better outcomes were observed in patients receiving the highest convection volumes.

International Comparisons of Prevalence, Awareness, and Treatment of Pruritus in People on Hemodialysis.

Background And Objectives: Uremic pruritus in patients on hemodialysis is associated with depression, lower quality of life, and mortality. We studied the prevalence, awareness, and treatment of pruritus to assess how well this important condition is currently managed internationally.

Design, Setting, Participants, & Measurements: Data from 35,452 patients on hemodialysis in up to 17 countries from the Dialysis Outcomes and Practice Patterns Study were analyzed to describe pruritus prevalence from 1996 to 2015.

A programme to spread eGFR graph surveillance for the early identification, support and treatment of people with progressive chronic kidney disease (ASSIST-CKD): protocol for the stepped wedge implementation and evaluation of an intervention to reduce late presentation for renal replacement therapy.

Background: Patients who start renal replacement therapy (RRT) for End-Stage Kidney Disease (ESKD) without having had timely access to specialist renal services have poor outcomes. At one NHS Trust in England, a community-wide CKD management system has led to a decline in the incident rate of RRT and the lowest percentage of patients presenting within 90 days of starting RRT in the UK. We describe the protocol for a quality improvement project to scale up and evaluate this innovation.

Reliability and validity of the coping strategy inventory-short form applied to hemodialysis patients in 13 countries: Results from the Dialysis Outcomes and Practice Patterns Study (DOPPS).

Objectives: The Coping Strategies Inventory-Short Form (CSI-SF) measures four coping strategies based on 16 items: 4 items each indicating problem- vs. emotion-focused engagement or disengagement. Here we provide the first assessment of reliability and construct validity of the CSI-SF among hemodialysis patients across 13 countries.

Association between changes in quality of life and mortality in hemodialysis patients: results from the DOPPS.

Background: Cross-sectional health-related quality of life (HR-QOL) measures are associated with mortality in hemodialysis (HD) patients. The impact of changes in HR-QOL on outcomes remains unclear. We describe the association of prior changes in HR-QOL with subsequent mortality among HD patients.

GPs' views on managing advanced chronic kidney disease in primary care: a qualitative study.

Background: Chronic kidney disease (CKD) has become a significant part of the GP's workload since the introduction of the National Institute for Health and Care Excellence guidelines in 2008. Patients with advanced CKD (stages G4 and G5) often have comorbidities, varied disease progression, and are likely to be older. GPs may experience difficulties with management decisions for patients with advanced CKD, including when to refer to nephrology.

Is there a difference in progression of renal disease between South Asian and white European diabetic adults with moderately reduced kidney function?

Aims: We examined potential ethnicity-related differences in progression of chronic kidney disease (CKD) between South Asian and white European diabetic adults with CKD stage 3 over a 5-year period.

Methods: We analysed data collected from diabetic adults of white European and South Asian ethnicity who had attended diabetes and diabetes-renal outpatient clinics with baseline estimated glomerular filtration rate (eGFR) values ≥30 and <60 ml/min/1.73 m(2) over 5 years (2005-2010); 891 (76%) were white Europeans, 282 (24%) were South Asians.
