Implementation of Ambulatory Kidney Supportive Care in a Safety Net Hospital

Scherer, Jennifer S; Gore, Radhika J; Georgia, Annette; Cohen, Susan E; Caplin, Nina; Zhadanova, Olga; Chodosh, Joshua; Charytan, David; Brody, Abraham A
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.

A pilot randomized controlled study of integrated kidney palliative care and chronic kidney disease care implemented in a safety-net hospital: Protocol for a pilot study of feasibility of a randomized controlled trial

Scherer, Jennifer S; Wu, Wenbo; Lyu, Chen; Goldfeld, Keith S; Brody, Abraham A; Chodosh, Joshua; Charytan, David
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.

Siriwardana, Amanda; Buizen, Luke; Jun, Min; Kotwal, Sradha; Arnott, Clare; Jardine, Meg J; Levin, Adeera; Heerspink, Hiddo J L; Charytan, David M; Pollock, Carol; Perkovic, Vlado; Neuen, Brendon L
AIM/OBJECTIVE:SGLT2 inhibitors may be underused in older adults with type 2 diabetes due to concerns about safety and tolerability. This pooled analysis of the CANVAS Program and CREDENCE trial examined the efficacy and safety of canagliflozin according to age. METHODS:Pooled individual participant data from the CANVAS Program (n = 10 142) and CREDENCE trial (n = 4401) were analysed by baseline age (<65 years, 65 to <75 years, and ≥75 years). A range of adjudicated clinical outcomes were assessed, including major adverse cardiovascular events and CKD progression, as well as safety outcomes. Cox proportional hazards models and Fine and Gray competing risk analysis were used. RESULTS:Among the 14 543 participants, 7927 (54.5%) were <65 years, 5281 (36.3%) were 65 to <75 years and 1335 (9.2%) were ≥75 years. Older participants had higher rates of atherosclerotic cardiovascular disease and heart failure, longer diabetes duration and lower mean eGFR. Reductions in cardiovascular and kidney outcomes with canagliflozin were consistent across age categories (all p trend >0.10), although there was some evidence that effects on cardiovascular death and all-cause death were attenuated with older age (p trend = 0.02 and 0.03, respectively). Although the incidence of adverse events increased with age, effects of canagliflozin on safety outcomes including acute kidney injury, volume depletion, urinary tract infections and hypoglycaemia, were not modified by age (all p trend >0.10). CONCLUSIONS:In patients with varying degrees of kidney function, canagliflozin reduced cardiovascular and kidney outcomes, regardless of age, with no additional safety concerns identified in older patients.

Moderate Kidney Dysfunction Independently Increases Sudden Cardiac Arrest Risk: A Community-Based Study

Truyen, Thien Tan Tri Tai; Uy-Evanado, Audrey; Chugh, Harpriya; Reinier, Kyndaron; Charytan, David M; Salvucci, Angelo; Jui, Jonathan; Chugh, Sumeet S
BACKGROUND/UNASSIGNED:Moderate kidney dysfunction is independently associated with increased cardiovascular mortality. Sudden cardiac arrest (SCA) accounts for at least 25% of chronic kidney disease (CKD) mortality. METHODS/UNASSIGNED:(2021 CKD-EPI formula). A population-based SCA study in Southern California was used for validation. RESULTS/UNASSIGNED:eGFR drop below 90 increased SCA risk (OR: 1.24, 95% CI: 1.18-1.31). Similar findings were observed in the validation cohort (817 SCA and 3,249 controls), where moderate CKD was associated with SCA (OR: 1.51, 95% CI: 1.16-1.97). CONCLUSION/UNASSIGNED:Moderate CKD is associated with an increased risk of SCA in the general population. Further research into the potential integration of moderate renal dysfunction into SCA risk stratification are warranted.

GLP-1 receptor agonists in kidney transplant recipients with pre-existing diabetes: a retrospective cohort study

Orandi, Babak J; Chen, Yusi; Li, Yiting; Metoyer, Garyn T; Lentine, Krista L; Weintraub, Michael; Bae, Sunjae; Ali, Nicole M; Lonze, Bonnie E; Ren-Fielding, Christine J; Lofton, Holly; Gujral, Akash; Segev, Dorry L; McAdams-DeMarco, Mara
BACKGROUND:Given the cardiovascular, renal, and survival benefits of GLP-1 receptor agonists for diabetes, these agents could be effective among kidney transplant recipients. However, kidney transplant recipients are distinct from GLP-1 receptor agonist trial participants, with longer diabetes duration and severity, greater end-organ damage, increased cardiovascular risk, and multimorbidity. We examined GLP-1 receptor agonist real-world effectiveness and safety in kidney transplant recipients with diabetes. METHODS:This USA-based retrospective cohort study included kidney transplant recipients with type 2 diabetes at transplantation and Medicare as their primary insurance from a national registry linked with Medicare claims. Post-transplantation GLP-1 receptor agonist use was identified through Medicare claims. Death-censored graft loss was estimated using the Fine-Gray sub-distribution hazard model and extended Cox models were used for mortality and safety endpoints. Models incorporated inverse probability of treatment weights. To further test whether bias could affect the main results, a cohort was created in which each GLP-1 receptor agonist user was matched with a kidney transplant recipient who had not started a GLP-1 receptor agonist, was alive with a functioning graft, and had accrued the same amount of post-transplant survival time. FINDINGS/RESULTS:Between Jan 1, 2013 and Dec 31, 2020, we identified 44 536 first time kidney transplant recipients with Medicare as primary payer in the 6 months before and at transplantation. 24 192 patients were excluded as they did not have type 2 diabetes. 2328 patients were ineligible (1916 had missing values and 412 used GLP-1 receptor agonists before transplantation). The primary cohort thus consisted of 18 016 kidney transplant recipients with diabetes. Of these patients, 1969 (10·9%) had at least one GLP-1 receptor agonist prescription filled post-transplant. Compared with patients who had not received a GLP-1 receptor agonist, GLP-1 receptor agonist users were younger (median age at transplant 57 years [IQR 49-64] vs 60 years [51-66], p<0·0001) and more likely to be female (786 [39·9%] vs 5645 [35·2%], p<0·0001). Among GLP-1 receptor agonist users, 552 [28·0%] were non-Hispanic White, 703 [35·7%] were non-Hispanic Black, and 568 [28·8%] were Hispanic. The 5-year unadjusted cumulative incidence of death-censored graft loss from a cohort matched on survival time before GLP-1 receptor agonist initiation was 6·0% for GLP-1 receptor agonist users and 10·7% for non-users (Gray's test p=0·004). The 5-year unadjusted cumulative incidence for mortality from a cohort matched on survival time before GLP-1 receptor agonist initiation was 17·0% for GLP-1 receptor agonist users and 25·8% for non-users (log-rank p=0·0006). The 5-year unadjusted cumulative incidence for mortality was 13·5% for GLP-1 receptor agonist users and 19·9% for non-users (log-rank p<0·0001). GLP-1 receptor agonist use was associated with a 49% lower incidence of death-censored graft loss (adjusted subhazard ratio [aSHR] 0·51, 95% CI 0·36-0·71; p=0·0001) and 31% lower mortality (adjusted hazard ratio [aHR] 0·69, 95% CI 0·55-0·86; p=0·001). Inferences were robust when matched on survival time (death-censored graft loss aSHR 0·53, 95% CI 0·37-0·75; p=0·0005; mortality aHR 0·70, 95% CI 0·55-0·88; p=0·003). Safety endpoints were rare and not associated with GLP-1 receptor agonists, with the exception of diabetic retinopathy (aHR 1·49, 1·11-2·00; p=0·008). INTERPRETATION/CONCLUSIONS:GLP-1 receptor agonists were associated with better graft and patient survival. Clinical trials are needed to confirm these findings.

Biomarker Panels for Predicting Progression of Kidney Disease in Acute Kidney Injury Survivors

Menez, Steven; Kerr, Kathleen F; Cheng, Si; Hu, David; Thiessen-Philbrook, Heather; Moledina, Dennis G; Mansour, Sherry G; Go, Alan S; Ikizler, T Alp; Kaufman, James S; Kimmel, Paul L; Himmelfarb, Jonathan; Coca, Steven G; Parikh, Chirag R
BACKGROUND:Acute kidney injury (AKI) increases the risk for chronic kidney disease (CKD). We aimed to identify combinations of clinical variables and biomarkers that predict long-term kidney disease risk after AKI. METHODS:We analyzed data from a prospective cohort of 723 hospitalized patients with AKI in the Assessment, Serial Evaluation, and Subsequent Sequelae of AKI (ASSESS-AKI) Study. Using machine learning, we investigated 75 candidate predictors including biomarkers measured at three-month post-discharge follow-up to predict major adverse kidney events (MAKE) within three years, defined as a decline in eGFR ≥40%, development of end-stage kidney disease (ESKD), or death. RESULTS:The mean age of study participants was 64 ± 13 years, 68% were men, and 79% were of White race. Two hundred and four (28%) patients developed MAKE over 3 years of follow-up. Random forest and LASSO penalized regression models using all 75 predictors yielded area under the receiver-operating characteristic curve (AUC) values of 0.80 (95% CI: 0.69-0.91) and 0.79 (95% CI: 0.68-0.90) respectively. The most consistently selected predictors were albuminuria, soluble tumor necrosis factor receptor 1 (sTNFR1), and diuretic use. A parsimonious model using the top eight predictor variables showed similarly strong discrimination for MAKE (AUC = 0.78; 95% CI: 0.66-0.90). Clinical impact utility analyses demonstrated that the eight-predictor model would have 55% higher efficiency of post-AKI care (number needed to screen/follow-up for a MAKE event decreased from 3.55 to 1.97). For a kidney-specific outcome of eGFR decline or ESKD, a four-predictor model showed strong discrimination (AUC = 0.82; 95% CI: 0.68-0.96). CONCLUSION/CONCLUSIONS:Combining clinical data and biomarkers can accurately identify high-risk AKI patients, enabling personalized post-AKI care and improved outcomes.

Establishing Research Priorities in Geriatric Nephrology: A Delphi Study of Clinicians and Researchers

Butler, Catherine R; Nalatwad, Akanksha; Cheung, Katharine L; Hannan, Mary F; Hladek, Melissa D; Johnston, Emily A; Kimberly, Laura; Liu, Christine K; Nair, Devika; Ozdemir, Semra; Saeed, Fahad; Scherer, Jennifer S; Segev, Dorry L; Sheshadri, Anoop; Tennankore, Karthik K; Washington, Tiffany R; Wolfgram, Dawn; Ghildayal, Nidhi; Hall, Rasheeda; McAdams-DeMarco, Mara
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.

Dember, Laura M; Hsu, Jesse Y; Mehrotra, Rajnish; Cavanaugh, Kerri L; Kalim, Sahir; Charytan, David M; Fischer, Michael J; Jhamb, Manisha; Johansen, Kirsten L; Becker, William C; Pellegrino, Bethany; Eneanya, Nwamaka D; Schrauben, Sarah J; Pun, Patrick H; Unruh, Mark L; Morasco, Benjamin J; Mehta, Mansi; Miyawaki, Nobuyuki; Penfield, Jeffrey; Bernardo, Leah; Brintz, Carrie E; Cheatle, Martin D; Doorenbos, Ardith Z; Heapy, Alicia A; Keefe, Francis J; Krebs, Erin E; Kuzla, Natalie; Nigwekar, Sagar U; Schmidt, Rebecca J; Steel, Jennifer L; Wetmore, James B; White, David M; Kimmel, Paul L; Cukor, Daniel
IMPORTANCE/UNASSIGNED:Chronic pain is common among individuals with dialysis-dependent kidney failure. OBJECTIVE/UNASSIGNED:To evaluate the effectiveness of pain coping skills training (PCST), a cognitive behavioral intervention, on pain interference. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This multicenter randomized clinical trial of PCST vs usual care was conducted across 16 academic centers and 103 outpatient dialysis facilities in the US. Adults undergoing maintenance hemodialysis and experiencing chronic pain were randomly assigned to PCST or usual care in a 1:1 ratio. Participants were followed in the trial for 36 weeks. Enrollment began on January 4, 2021, and follow-up ended on December 21, 2023. INTERVENTIONS/UNASSIGNED:PCST consisting of 12 weekly coach-led sessions via video or telephone conferencing, followed by 12 weeks of daily interactive voice response sessions. Usual care had no trial-driven pain intervention. MAIN OUTCOMES/UNASSIGNED:The primary outcome was pain interference measured with the Brief Pain Inventory (BPI) Interference subscale (score range of 0-10, with higher scores indicating more pain interference). Secondary outcomes included pain intensity, pain catastrophizing, quality of life, depression, and anxiety. RESULTS/UNASSIGNED:A total of 643 participants (mean [SD] age, 60.3 [12.6] years; 288 [44.8%] female) were randomized, with 319 assigned to PCST and 324 assigned to usual care. At week 12 (primary end point), the PCST group had a larger reduction in the BPI Interference score than the usual care group (between-group difference, -0.49; 95% CI, -0.85 to -0.12; P = .009). The effect persisted at week 24 (between-group difference in BPI Interference score, -0.48; 95% CI, -0.86 to -0.11) but was diminished at week 36 (between-group difference in BPI Interference score, -0.34; 95% CI, -0.72 to 0.04). A decrease in BPI Interference score greater than 1 point (minimal clinically important difference) occurred in 143 of 281 participants (50.9%) in the PCST group vs 108 of 295 participants (36.6%) in the usual care group at 12 weeks (odds ratio, 1.79; 95% CI, 1.28-2.49) and 142 of 258 participants (55.0%) in the PCST group vs 113 of 264 participants (42.8%) in the usual care group at 24 weeks (odds ratio, 1.59; 95% CI, 1.13-2.24). Favorable changes with PCST were also apparent for secondary outcomes of pain intensity, quality of life, depression, and anxiety at weeks 12 and/or 24, as well as for pain catastrophizing at weeks 24 and 36. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this randomized clinical trial of patients undergoing maintenance hemodialysis, PCST had benefits on pain interference and other pain-associated outcomes. While the effect on the overall cohort was of modest magnitude, the intervention resulted in a clinically meaningful improvement in pain interference for a substantial proportion of participants.
