Conservative Management is customized CKD care, symptom management, and support to navigate care across the CKD trajectory through end of life. Conservative management is defined by shared decision-making and interdisciplinary teamwork in alliance with patients and care partners. Implementation of conservative management hinges on each practice's logistical considerations and resource availability.Conservative management is holistic and whole-person care for people with kidney failure. This care pathway is often a good choice for patients who prioritize independence, quality of life, and avoidance of burdens associated with life prolonging therapies such as dialysis. This Kidney Health Guidance document aims to provide evidence-based clinical guidance for best practices in conservative management care delivery. Conservative management comprises three components including customized CKD care, symptom management, and smooth navigation of care transitions. This Kidney Health Guidance describes the application of these three components across the illness trajectory, including the role of shared decision-making, care partner engagement, and interdisciplinary collaboration. Practical strategies are outlined for health care professionals to integrate conservative management care delivery into practice.

BACKGROUND:People on hemodialysis (HD) often report lower quality of life (QoL) compared to people not on HD. People with kidney disease have a high prevalence of health-related social needs (HRSN). The association of HRSN and QoL in people on HD remains understudied. Though some groups of patients treated with HD tend to have lower QoL, there exists minimal research investigating the mechanism by which this occurs. METHODS:We surveyed people receiving HD at five urban dialysis units using the Kidney Disease Quality of Life (KDQOL) and the Accountable Health Communities Health-Related Social Needs Screening Tool (AHC-HRSN) to assess their housing, food, transportation, utilities, and perceived safety. We calculated physical and mental component scores as well as sub scores measuring burden, symptoms, and effect of kidney disease. We analyzed scores using Python packages. We used the Shapiro-Wilk test to assess normality. For analysis we used the Wilcoxon Rank Sum test and univariate, multivariate, and LASSO regressions. RESULTS:A total of 324 patients participated in the study. HRSN was common with 56% of participants reporting at least one HRSN. Food insecurity (35%) and housing instability (24%) was most common. All QoL sub scores were significantly lower in patients who had at least one HRSN. In regression models, housing and transportation insecurity most frequently emerged as significant variables associated with lower QoL sub scores even after adjusting for patient demographics. Burden scores showed the largest effect sizes (housing instability β=-17.90, P<0.001, transportation problems β=-14.03, P=0.001). CONCLUSION/CONCLUSIONS:HRSN is significantly associated with lower QoL scores, with largest effect sizes seen with housing instability and transportation problems. Increased screening and intervention for HRSN may improve QoL among people on HD.

RATIONALE & OBJECTIVE/OBJECTIVE:Adults receiving maintenance hemodialysis (HD) frequently report pain, yet detailed descriptions of pain in this population are lacking. This study examines pain locations, characteristics, and associations with other symptoms in adults receiving HD. STUDY DESIGN/METHODS:Cross-sectional analysis. SETTING & PARTICIPANTS/METHODS:Adults with moderate to severe chronic pain receiving maintenance HD enrolled in the multicenter HOPE Consortium Trial from 2021 to 2023. EXPOSURES/METHODS:Sociodemographic, pain treatment, dialysis, medical comorbidity, and psychological and behavioral characteristics. Other patient-reported symptoms. OUTCOME/RESULTS:Pain interference and severity as assessed by the Brief Pain Inventory (BPI) Interference and Severity subscales (range 0-10). ANALYTICAL APPROACH/METHODS:Multivariable regression with LASSO to examine associations between participant characteristics and pain interference/severity, and Spearman's correlation to examine relationships between other symptoms and pain interference/severity at baseline. RESULTS:Among 643 participants, the median (IQR) BPI interference was 6.6 (5.1-7.9) and severity was 6.0 (4.5-7.5). 84% of participants reported pain >1 year and 75% had daily pain. 89% and 66% of participants endorsed musculoskeletal and neuropathic pain, respectively. Of 32 body regions, the median (IQR) number of painful regions was 8 (4-14). C ommon regions in females were lower back (72%), knees (64%), legs (60%), and upper back (59%). A similar pattern existed for males. In LASSO analyses, cardiovascular disease and depression were associated with significantly higher pain interference whereas White race (ref: Black race) and non-Hispanic ethnicity were associated with significantly lower pain interference. Similar findings were noted for pain severity. Pain catastrophizing and symptoms of fatigue, depression, and anxiety were moderately correlated with pain interference (r>0.4). LIMITATIONS/CONCLUSIONS:Neither relationship directionality nor causality can be inferred. CONCLUSIONS:Among adults treated with HD who have chronic pain, pain locations were numerous and diverse, with substantial musculoskeletal and neuropathic characteristics. Factors associated with pain interference were predominantly sociodemographic and psychological rather than those related to comorbid diseases and dialysis.

Community input enhances the impact of research. Yet, there are challenges when eliciting community perspectives in nephrology/transplant research: recruitment of patients across a wide spectrum of familiarity with kidney disease; a lack of trust from marginalized patients because of health care barriers, institutionalized structural racism, and historical harm; and retention of members facing high burden of care. To address these challenges, we drafted a mission and formed a community advisory board to provide input on nephrology/transplant research. We worked with kidney disease community organizations that prioritize diversity and equity to recruit members with chronic kidney disease, end-stage kidney disease, or a kidney transplant, as well as nephrology/transplant caregivers and kidney donors. We formed a diverse group of 9 members and received feedback on 5 research proposals over 4 quarterly meetings, bridging a communication gap between community perspectives and researchers. The collaborative environment stimulated feedback that improved our nephrology/transplant research to reflect the perspectives of those most affected by research findings. Eight members have remained active for more than 1 year. In this collaborative paper, we describe our process of forming a nephrology/transplant community advisory board, and participants highlight the benefits of sharing their lived experiences to improve and amplify the impact of nephrology/transplant research.

BACKGROUND:Falls are thought to be common in patients undergoing maintenance hemodialysis, but little is known about their frequency or outcomes. In this prospective study, we sought to increase our knowledge regarding the incidence, timing, circumstances, and outcomes of falls in this population. METHODS:Between January 2021 and April 2023, adults undergoing maintenance hemodialysis from 103 U.S. dialysis facilities were enrolled in the HOPE Consortium trial, which randomized participants with moderate or severe chronic pain to a pain coping skills cognitive behavioral therapy intervention or usual care. Occurrence of falls was a pre-specified trial outcome. The research team inquired about falls at each four-week follow-up visit during the 36-week study. Multivariable regression was used to explore associations of demographic and clinical characteristics, including patient-reported symptoms, with fall risk. RESULTS:Of 643 trial participants, 178 (28%) experienced 293 falls over a cumulative follow-up period of 429 participant-years for an overall rate of 0.68 falls per participant-year (95% CI: 0.61, 0.76). Accidents were the most frequent cause of falls (38%). It was rare for falls to be related to the hemodialysis treatment or to occur in the hemodialysis unit. Of the 293 falls, 36 (12%) were evaluated in the emergency department without subsequent hospitalization, 41 (14%) resulted in a hospital admission, and 19 (7%) led to a fracture. In multivariable analyses, neither demographic characteristics severity of pain symptoms or medication use such as opioids at enrollment was associated with the fall risk. CONCLUSIONS:Falls were common in this cohort of maintenance hemodialysis patients with chronic pain, occurring in 28% of individuals during a planned follow-up of 36 weeks. Falls rarely occurred in the dialysis unit, with the vast majority occurring at participants' homes and due to accidental causes. There was no significant association between patient-reported symptoms or medication use and the risk of subsequent falls. TRIAL REGISTRATION/BACKGROUND:NCT04571619.

CONTEXT/BACKGROUND:Chronic kidney disease (CKD) disproportionately impacts lower socioeconomic groups and is associated with many symptoms and complex decisions. Integration of Kidney Supportive Care (KSC) with CKD care can address these needs. To our knowledge, this approach has not been described in an underserved population. OBJECTIVES/OBJECTIVE:We describe our adaptation of an ambulatory integrated KSC and CKD clinic for implementation in a safety net hospital. We report our utilization metrics; characteristics of the population served; and visit activities. METHODS:We considered modifications from the perspectives of people with CKD, their providers, and the health system. Modifications were informed by meeting notes with key participants (hospital administrators [n = 5], funders [n = 1], and content experts [n = 2]), as well as literature on palliative care program building, safety net hospitals, and KSC. We extracted utilization data for the first 15 months of the clinic's operations, demographics, clinical characteristics, unmet health related social needs, and symptom burden, measured by the Integrated Palliative Outcome Scale-Renal (total Score, and sub-scores of physical, psychological, and practical impact of CKD) from the electronic health record. Results are reported using descriptive statistics. RESULTS:Adaptions were proactive and done by clinical and administrative leaders. Meetings identified challenges of the safety net setting including people presenting with advanced disease and having several social needs. Modifications to our base model were made in staffing, data collection, and work flow. Show rate was approximately 68%, with a majority of people identifying as Black or Hispanic, and uninsured or on Medicaid. Symptom burden was lower than previous reports, driven by a better psychological sub-score. CONCLUSIONS:We describe a feasible ambulatory care model of KSC in a safety net setting that can serve as a framework for the development of other noncancer palliative care ambulatory clinics. Future work will optimize our model.

BACKGROUND/UNASSIGNED:Chronic kidney disease (CKD) impacts more than 800 million people. It causes significant suffering and disproportionately impacts marginalized populations in the United States. Kidney palliative care has the potential to alleviate this distress, but has not been tested. This pilot study evaluates the feasibility of a randomized clinical trial (RCT) testing the efficacy of integrated kidney palliative and CKD care in an urban safety-net hospital. METHODS/UNASSIGNED:, and are receiving care at our safety net hospital. Participants will be randomized in permuted blocks of two or four to either the intervention group, who will receive monthly ambulatory care visits for six months with a palliative care provider trained in kidney palliative care, or to usual nephrology care. Primary outcomes are feasibility of recruitment, retention, fidelity to the study visit protocol, and the ability to collect outcome data. These outcomes include symptom burden, quality of life, and engagement in advance care planning. DISCUSSION/UNASSIGNED:This pilot RCT will provide essential data on the feasibility of testing integrated palliative care in CKD care in an underserved setting. These outcomes will inform a larger, fully powered trial that tests the efficacy of our kidney palliative care approach. CLINICAL TRIAL REGISTRATION/UNASSIGNED:NCT04998110.

RATIONALE & OBJECTIVE/OBJECTIVE:Despite substantial growth in the population of older adults with kidney disease, there remains a lack of evidence to guide clinical care for this group. The Kidney Disease and Aging Research Collaborative (KDARC) conducted a Delphi study to build consensus on research priorities for clinical geriatric nephrology. STUDY DESIGN/METHODS:Asynchronous modified Delphi study. SETTING & PARTICIPANTS/METHODS:Clinicians and researchers in the US and Canada with clinical experience and/or research expertise in geriatric nephrology. OUTCOME/RESULTS:Research priorities in geriatric nephrology. ANALYTICAL APPROACH/METHODS:In the first Delphi round, participants submitted free-text descriptions of research priorities considered important for improving the clinical care of older adults with kidney disease. Delphi moderators used inductive content analysis to group concepts into categories. In the second and third rounds, participants iteratively reviewed topics, selected their top 5 priorities, and offered comments used to revise categories. RESULTS:Among 121 who were invited, 57 participants (47%) completed the first Delphi round and 48 (84% of enrolled participants) completed all rounds. After 3 rounds, the 5 priorities with the highest proportion of agreement were: 1) Communication and Decision-Making about Treatment Options for Older Adults with Kidney Failure (69% agreement), 2) Quality of Life, Symptom Management, and Palliative Care (67%), 3) Frailty and Physical Function (54%), 4) Tailoring Therapies for Kidney Disease to Specific Needs of Older Adults (42%), and 5) Caregiver and Social Support (35%). Health equity and person-centricity were identified as cross-cutting features that informed all topics. LIMITATIONS/CONCLUSIONS:Relatively low response rate and limited participation by private practitioners and older clinicians and researchers. CONCLUSIONS:Experts in geriatric nephrology identified clinical research priorities with the greatest potential to improve care for older adults with kidney disease. These findings provide a roadmap for the geriatric nephrology community to harmonize and maximize the impact of research efforts.

BACKGROUND:Though older adults with chronic kidney disease (CKD) have a greater mortality risk than those without CKD, traditional risk factors poorly predict mortality in this population. Therefore, we tested our hypothesis that two common geriatric risk factors, frailty and cognitive impairment, and their co-occurrence, might improve mortality risk prediction in CKD. METHODS:Among participants aged ≥ 60 years from National Health and Nutrition Examination Survey (2011-2014), we quantified associations between frailty (physical frailty phenotype) and global/domain-specific cognitive function (immediate-recall [CERAD-WL], delayed-recall [CERAD-DL], verbal fluency [AF], executive function/processing speed [DSST], and global [standardized-average of 4 domain-specific tests]) using linear regression, and tested whether associations differed by CKD using a Wald test. We then tested whether frailty, global cognitive impairment (1.5SD below the mean), or their combination improved prediction of mortality (Cox models, c-statistics) compared to base models (likelihood-ratios) among those with and without CKD. RESULTS: < 0.001) but not cognitive impairment. CONCLUSIONS:Frailty is associated with worse cognitive function regardless of CKD status. While CKD and frailty improved mortality prediction, cognitive impairment did not. Risk prediction tools should incorporate frailty to improve mortality prediction among those with CKD.
