Patient navigator programs may improve outcomes among individuals with chronic kidney disease by reducing barriers to evidence-based care. The NAVKIDS 2 trial evaluated a patient navigation program among 162 children with chronic kidney disease from marginalized populations. The intervention was not associated with quantitative changes in self-reported health, but qualitative data indicated substantial benefit in alleviating caregiver strain and facilitating care coordination. Future studies should identify quantitative measures that capture the benefits experienced by patients in care coordination, empowerment, and self-management., (Copyright © 2024 International Society of Nephrology.

Aim: To explore the influence of patient-provider communication on patient self-management of chronic illness., Design: Systematic Mixed Studies Review., Data Sources: CINAHL, Google Scholar, EMBASE and PubMed were searched until March 2024., Methods: Employed a result-based convergent design and the Mixed Method Appraisal Tool to evaluate studies. Narrative analysis, quantitative studies and thematic analysis for qualitative studies and overall results., Results: Thirteen articles published between 2003 and 2023 were included. Chronic illnesses studied: diabetes, heart failure, hypertension, chronic obstructive pulmonary disease and asthma. Data synthesis yielded the overarching theme: adaptive interpersonal communication. An approach that adapts communication content to each patient's unique needs, employs verbal and nonverbal communication, builds a connection and establishes patient rapport., Conclusion: Available evidence suggests that patient-provider communication influences chronic illness self-management. A provider's ability to adjust and tailor their communication style is an important factor in helping patients to achieve optimal self-management. Future research should explore this phenomenon in other common chronic illnesses not included in this review. Additionally, research on the patient's role in this process could help improve patient-provider communication., Implications for the Profession And/or Patient Care: Findings from this review have significant implications for shared and participatory decision making, where patients and providers collaborate to develop plans of care for patients to achieve optimal self-management. Additionally, this review can contribute to the development of educational content and communication strategies for nurses and all healthcare professionals caring for patients with chronic illnesses., Impact: This is the first mixed studies systematic review to describe the influence patient-provider communication on patient self-management of chronic illness. These findings consolidate existing evidence, providing a pathway for practical application to clinical practice and the potential to significantly impact the delivery of patient-centred care and healthcare quality., Patient or Public Contribution: No patient or public contribution., (© 2024 The Author(s).

Background: Many patients with diabetic kidney disease (DKD) do not receive evidence-based, guideline-recommended treatment shown to reduce DKD progression and complications. Proactive electronic consultations (e-consults) are an emerging intervention strategy that could potentially allow nephrologists to provide timely and evidence-based guidance to primary care providers (PCPs) engaged in early DKD care., Methods: The objective of this study was to explore perspectives about potential barriers and facilitators associated with a proactive e-consult program to improve DKD care delivery. We conducted semi-structured qualitative interviews with PCPs across three different health systems. Interview transcripts were reviewed in a rapid qualitative analysis approach to iteratively identify, refine, and achieve consensus on a final list of themes and subthemes., Results: A total of 18 interviews were conducted. PCPs across all sites identified similar challenges to delivering guideline-recommended DKD care. PCPs were supportive of the proactive e-consult concept. Three major themes emerged surrounding (1) perceived potential benefits of proactive e-consults, including educational value and improved specialist access; (2) concerns about the proactive nature of e-consults, including the potential to increase PCP workload and the possibility that e-consults could be seen as documenting substandard care; and (3) leveraging of care teams to facilitate recommended DKD care, such as engaging clinic-based pharmacists to implement specialist recommendations from e-consults., Conclusion: In this pre-implementation qualitative study, PCPs noted potential benefits and identified concerns and implementation barriers for proactive e-consults for DKD care. Strategies that emerged for promoting successful implementation included involving clinic support staff to enact e-consult recommendations and framing e-consults as a system improvement effort to avoid judgmental associations., (© 2024.

Background: The prevalence of telehealth video use across the United States is uneven, with low uptake in safety-net health care delivery systems, which care for patient populations who face barriers to using digital technologies., Objective: This study aimed to increase video visit use in an urban safety-net delivery system. We piloted a telehealth ambassador program, in which volunteers offered technical support to patients with access to digital technologies to convert primary care visits already scheduled as telehealth audio-only visits to telehealth video visits., Methods: We used a descriptive approach to assess the feasibility, efficacy, and acceptability of the pilot telehealth ambassador program. Feasibility was quantified by the percentage of eligible patients who answered calls from telehealth ambassadors. Program efficacy was measured in two ways: (1) the percentage of patients with access to digital technology who interacted with the navigators and were successfully prepared for a telehealth video visit, and (2) the percentage of prepared patients who completed their scheduled video visits. Program acceptability was ascertained by a structured telephone survey., Results: Telehealth ambassadors attempted to contact 776 eligible patients; 43.6% (338/776) were reached by phone, among whom 44.4% (150/338) were provided digital support between March and May 2021. The mean call duration was 8.8 (range 0-35) minutes. Overall, 67.3% (101/150) of patients who received support successfully completed a telehealth video visit with their provider. Among the 188 patients who were contacted but declined video visit digital support, 61% (114/188) provided a reason for their decline; 42% (48/114) did not see added value beyond a telehealth audio-only visit, 20% (23/114) had insufficient internet access, and 27% (31/114) declined learning about a new technology. The acceptability of the telehealth ambassador program was generally favorable, although some patients preferred having in-real-time technology support on the day of their telehealth video visit., Conclusions: This high-touch program reached approximately one-half of eligible patients and helped two-thirds of interested patients with basic video visit capability successfully complete a video visit. Increasing the program's reach will require outreach solutions that do not rely solely on phone calls. Routinely highlighting the benefits of video visits, partnering with community-based organizations to overcome structural barriers to telehealth use, and offering in-real-time technology support will help increase the program's efficacy., (©Delphine S Tuot, Aarya Mukherjee, Amanda Churape, Triveni DeFries, George Su, Elaine C Khoong, Courtney Lyles.

Background: Intensive BP lowering in the Systolic Blood Pressure Intervention Trial (SPRINT) produced acute decreases in kidney function and higher risk for AKI. We evaluated the effect of intensive BP lowering on long-term changes in kidney function using trial and outpatient electronic health record (EHR) creatinine values., Methods: SPRINT data were linked with EHR data from 49 (of 102) study sites. The primary outcome was the total slope of decline in eGFR for the intervention phase and the post-trial slope of decline during the observation phase using trial and outpatient EHR values. Secondary outcomes included a ≥30% decline in eGFR to <60 ml/min per 1.73 m 2 and a ≥50% decline in eGFR or kidney failure among participants with baseline eGFR ≥60 and <60 ml/min per 1.73 m 2 , respectively., Results: EHR creatinine values were available for a median of 8.3 years for 3041 participants. The total slope of decline in eGFR during the intervention phase was -0.67 ml/min per 1.73 m 2 per year (95% confidence interval [CI], -0.79 to -0.56) in the standard treatment group and -0.96 ml/min per 1.73 m 2 per year (95% CI, -1.08 to -0.85) in the intensive treatment group ( P < 0.001). The slopes were not significantly different during the observation phase: -1.02 ml/min per 1.73 m 2 per year (95% CI, -1.24 to -0.81) in the standard group and -0.85 ml/min per 1.73 m 2 per year (95% CI, -1.07 to -0.64) in the intensive group. Among participants without CKD at baseline, intensive treatment was associated with higher risk of a ≥30% decline in eGFR during the intervention (hazard ratio, 3.27; 95% CI, 2.43 to 4.40), but not during the postintervention observation phase. In those with CKD at baseline, intensive treatment was associated with a higher hazard of eGFR decline only during the intervention phase (hazard ratio, 1.95; 95% CI, 1.03 to 3.70)., Conclusions: Intensive BP lowering was associated with a steeper total slope of decline in eGFR and higher risk for kidney events during the intervention phase of the trial, but not during the postintervention observation phase., (Copyright © 2023 by the American Society of Nephrology.)

Background and objective Hemodialysis patients often have lower serum low-density lipoprotein (LDL) and total cholesterol concentrations compared to the general population. It is unclear if this is due to a persistent decline in the values due to kidney disease or if the hemodialysis itself is contributing to the lower values. It is often assumed that malnutrition and anorexia are the main causes of the low lipid concentration in hemodialysis patients. In this study, we aimed to determine the association between hemodialysis initiation and serum lipid and albumin concentrations. Methodology The medical records of all patients initiating hemodialysis over an 11-year period at a single center were retrospectively reviewed. The data of 145 patients who had all the required lab values available were ultimately included in the study. Serum lipid levels at the initiation of hemodialysis were compared to values obtained mostly 6-18 months later. In order to determine if poor nutritional status is the reason for the decline in serum lipid levels, the serum albumin concentration at the initiation of hemodialysis was compared to that obtained during follow-up labs. Results We observed that serum cholesterol concentration declined from an average of 147 mg/dL to 137 mg/dL, while LDL decreased from an average of 78 mg/dL to 68 mg/dL, and serum albumin concentration increased from 3.4 g/dL to 3.8 g/dL after an average follow-up period of 10.8 months. Conclusions Based on our findings, the decline in serum LDL and total cholesterol concentrations with the initiation of hemodialysis may not be attributed to poor nutritional intake., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Sam et al.)

Rationale & Objective: The Kidney Failure Risk Equation (KFRE) predicts the 2-year risk of kidney failure for patients with chronic kidney disease (CKD). Translating KFRE-predicted risk or estimated glomerular filtration rate (eGFR) into time to kidney failure could inform decision making for patients approaching kidney failure., Study Design: Retrospective cohort., Setting & Participants: CKD Outcomes and Practice Patterns Study (CKDOPPS) cohort of patients with an eGFR<60mL/min/1.73m 2 from 34 US nephrology practices (2013-2021)., Exposure: 2-year KFRE risk or eGFR., Outcome: Kidney failure defined as initiation of dialysis or kidney transplantation., Analytical Approach: Accelerated failure time (Weibull) models used to estimate the median, 25th, and 75th percentile times to kidney failure starting from KFRE values of 20%, 40%, and 50%, and from eGFR values of 20, 15, and 10mL/min/1.73m 2 . We examined variability in time to kidney failure by age, sex, race, diabetes status, albuminuria, and blood pressure., Results: Overall, 1,641 participants were included (mean age 69±13 years; median eGFR of 28mL/min/1.73m 2 [IQR 20-37mL/min/1.73 m 2 ]). Over a median follow-up period of 19 months (IQR, 12-30 months), 268 participants developed kidney failure, and 180 died before reaching kidney failure. The median estimated time to kidney failure was widely variable across patient characteristics from an eGFR of 20mL/min/1.73m 2 and was shorter for younger age, male sex, Black (versus non-Black), diabetes (vs no diabetes), higher albuminuria, and higher blood pressure. Estimated times to kidney failure were comparably less variable across these characteristics for KFRE thresholds and eGFR of 15 or 10mL/min/1.73m 2 ., Limitations: Inability to account for competing risks when estimating time to kidney failure., Conclusions: Among those with eGFR<15mL/min/1.73m 2 or KFRE risk>40%), both KFRE risk and eGFR showed similar relationships with time to kidney failure. Our results demonstrate that estimating time to kidney failure in advanced CKD can inform clinical decisions and patient counseling on prognosis, regardless of whether estimates are based on eGFR or the KFRE., Plain-Language Summary: Clinicians often talk to patients with advanced chronic kidney disease about the level of kidney function expressed as the estimated glomerular filtration rate (eGFR) and about the risk of developing kidney failure, which can be estimated using the Kidney Failure Risk Equation (KFRE). In a cohort of patients with advanced chronic kidney disease, we examined how eGFR and KFRE risk predictions corresponded to the time patients had until reaching kidney failure. Among those with eGFR<15mL/min/1.73m 2 or KFRE risk > 40%), both KFRE risk and eGFR showed similar relationships with time to kidney failure. Estimating time to kidney failure in advanced CKD using either eGFR or KFRE can inform clinical decisions and patient counseling on prognosis., (Copyright © 2023 The Authors.

Objective: To evaluate the fulfillment and validity of the kidney health evaluation for people with diabetes (KED) Healthcare Effectiveness Data Information Set (HEDIS) measure., Patients and Methods: Optum Labs Data Warehouse (OLDW) was used to identify the nationally distributed US population aged 18 years and older, with diabetes, between January 1, 2017, and December 31, 2017. The OLDW includes deidentified medical, pharmacy, laboratory, and electronic health record (EHR) data. The KED fulfillment was defined in 2017 as both estimated glomerular filtration rate (eGFR) and urinary albumin-creatinine ratio testing within the measurement year. The KED validity was assessed using bivariate analyses of KED fulfillment with diabetes care measures in 2017 and chronic kidney disease (CKD) diagnosis and evidence-based kidney protective interventions in 2018., Results: Among eligible 5,635,619 Medicare fee-for-service beneficiaries, 736,875 Medicare advantage (MA) beneficiaries, and 660,987 commercial patients, KED fulfillment was 32.2%, 38.7%, and 37.7%, respectively. Albuminuria testing limited KED fulfillment with urinary albumin-creatinine ratio testing (<40%) and eGFR testing (>90%). The KED fulfillment was positively associated with receipt of diabetes care in 2017, CKD diagnosis in 2018, and evidence-based kidney protective interventions in 2018. The KED fulfillment trended lower for Black race, Medicare-Medicaid dual eligibility status, low neighborhood income, and low education status., Conclusion: Less than 40% of adults with diabetes received guideline-recommended testing for CKD in 2017. Routine KED was associated with diabetes care and evidence-based CKD interventions. Increasing guideline-recommended testing for CKD among people with diabetes should lead to timely and equitable CKD detection and treatment., Competing Interests: J.A.V. reports honoraria from Renalytix, PLC.

Importance: Albuminuria testing is crucial for guiding evidence-based treatments to mitigate chronic kidney disease (CKD) progression and cardiovascular morbidity, but it is widely underutilized among persons with or at risk for CKD., Objective: To estimate the extent of albuminuria underdetection from lack of testing and evaluate its association with CKD treatment in a large US cohort of patients with hypertension or diabetes., Design, Setting, and Participants: This cohort study examined adults with hypertension or diabetes, using data from the 2007 to 2018 National Health and Nutrition Examination Surveys (NHANES) and the Optum deidentified electronic health record (EHR) data set of diverse US health care organizations. Analyses were conducted from October 31, 2022, to May 19, 2023., Main Outcomes and Measures: Using NHANES as a nationally representative sample, a logistic regression model was developed to estimate albuminuria (urine albumin-creatinine ratio ≥30 mg/g). This model was then applied to active outpatients in the EHR from January 1, 2017, to December 31, 2018. The prevalence of albuminuria among those with and without albuminuria testing during this period was estimated. A multivariable logistic regression was used to examine associations between having albuminuria testing and CKD therapies within the subsequent year (prescription for angiotensin-converting enzyme inhibitor [ACEi] or angiotensin II receptor blocker [ARB], prescription for sodium-glucose cotransporter 2 inhibitor [SGLT2i], and blood pressure control to less than 130/80 mm Hg or less than 140/90 mm Hg on the latest outpatient measure)., Results: The total EHR study population included 192 108 patients (mean [SD] age, 60.3 [15.1] years; 185 589 [96.6%] with hypertension; 50 507 [26.2%] with diabetes; mean [SD] eGFR, 84 [21] mL/min/1.73 m2). There were 33 629 patients (17.5%) who had albuminuria testing; of whom 11 525 (34.3%) had albuminuria. Among 158 479 patients who were untested, the estimated albuminuria prevalence rate was 13.4% (n = 21 231). Thus, only 35.2% (11 525 of 32 756) of the projected population with albuminuria had been tested. Albuminuria testing was associated with higher adjusted odds of receiving ACEi or ARB treatment (OR, 2.39 [95% CI, 2.32-2.46]), SGLT2i treatment (OR, 8.22 [95% CI, 7.56-8.94]), and having blood pressure controlled to less than 140/90 mm Hg (OR, 1.20 [95% CI, 1.16-1.23])., Conclusions and Relevance: In this cohort study of patients with hypertension or diabetes, it was estimated that approximately two-thirds of patients with albuminuria were undetected due to lack of testing. These results suggest that improving detection of CKD with albuminuria testing represents a substantial opportunity to optimize care delivery for reducing CKD progression and cardiovascular complications.

Blood and urine tests are commonly performed by clinicians in both ambulatory and hospital settings that detect chronic and acute kidney disease. Thresholds for these tests have been established that signal the presence and severity of kidney injury or dysfunction. In the appropriate clinical context of a patient's history and physical examination, an abnormal test result should trigger specific actions for clinicians, including reviewing patient medication use, follow-up testing, prescribing lifestyle modifications, and specialist referral. Tests for kidney disease can also be used to determine the future risk for kidney failure as well as cardiovascular death., Competing Interests: Disclosures: All relevant financial relationships have been mitigated.

Background: Randomized trials are the gold standard for generating clinical practice evidence, but follow-up and outcome ascertainment are resource-intensive. Electronic health record (EHR) data from routine care can be a cost-effective means of follow-up, but concordance with trial-ascertained outcomes is less well-studied., Methods: We linked EHR and trial data for participants of the Systolic Blood Pressure Intervention Trial (SPRINT), a randomized trial comparing intensive and standard blood pressure targets. Among participants with available EHR data concurrent to trial-ascertained outcomes, we calculated sensitivity, specificity, positive predictive value, and negative predictive value for EHR-recorded cardiovascular disease (CVD) events, using the gold standard of SPRINT-adjudicated outcomes (myocardial infarction (MI)/acute coronary syndrome (ACS), heart failure, stroke, and composite CVD events). We additionally compared the incidence of non-CVD adverse events (hyponatremia, hypernatremia, hypokalemia, hyperkalemia, bradycardia, and hypotension) in trial versus EHR data., Results: 2468 SPRINT participants were included (mean age 68 (SD 9) years; 26% female). EHR data demonstrated ≥80% sensitivity and specificity, and ≥ 99% negative predictive value for MI/ACS, heart failure, stroke, and composite CVD events. Positive predictive value ranged from 26% (95% CI; 16%, 38%) for heart failure to 52% (95% CI; 37%, 67%) for MI/ACS. EHR data uniformly identified more non-CVD adverse events and higher incidence rates compared with trial ascertainment., Conclusions: These results support a role for EHR data collection in clinical trials, particularly for capturing laboratory-based adverse events. EHR data may be an efficient source for CVD outcome ascertainment, though there is clear benefit from adjudication to avoid false positives., Competing Interests: Declaration of Competing Interest CDC receives research support from Bayer Healthcare, Inc. outside the submitted work.

Early nephrology specialty care slows progression of chronic kidney disease (CKD) to end-stage renal disease (ESRD). However, identifying which patients are expected to progress to end-stage disease has been historically challenging to predict. With a limited supply of nephrologists, optimizing nephrology referral is essential for improving patient outcomes. The Kidney Failure Risk Equation (KFRE) provides an accurate metric to identify patients who are at high risk of progression to kidney failure. In this study, we utilize the KFRE to perform a retrospective analysis in a local health network to identify rates of nephrology referral for CKD patients stratified by risk of kidney failure progression. We found a nephrology referral gap in CKD patients at higher risk of progression and an underutilization of albuminuria testing in CKD, suggesting opportunities to improve outcomes by 1) proactively targeting high-risk patients using EHR-based informatics strategies and 2) increasing albuminuria testing as a screening tool., (©2022 AMIA - All rights reserved.)

Background: Electronic consultation (eConsult) programs are crucial components of modern healthcare that facilitate communication between primary care providers (PCPs) and specialists. eConsults between PCPs and specialists. They also provide a unique opportunity to use real-world patient scenarios for reflective learning as part of professional development. However, tools that guide and document learning from eConsults are limited. The purpose of this study was to develop and pilot two eConsult reflective learning tools (RLTs), one for PCPs and one for specialists, for those participating in eConsults., Methods: We performed a four-phase pragmatic mixed methods study recruiting PCPs and specialists from two public health systems located in two countries: eConsult BASE in Canada and San Francisco Health Network eConsult in the United States. In phase 1, subject matter experts developed preliminary RLTs for PCPs and specialists. During phase 2, a Delphi survey among 20 PCPs and 16 specialists led to consensus on items for each RLT. In phase 3, we conducted cognitive interviews with three PCPs and five specialists as they applied the RLTs on previously completed consults. In phase 4, we piloted the RLTs with eConsult users., Results: The RLTs were perceived to elicit critical reflection among participants regarding their knowledge and practice habits and could be used for quality improvement and continuing professional development., Conclusion: PCPs and specialists alike perceived that eConsult systems provided opportunities for self-directed learning wherein they were motivated to investigate topics further through the course of eConsult exchanges. We recommend the RLTs be subject to further evaluation through implementation studies at other sites., (© 2023. The Author(s).)

Objective: To assess the prevalence and correlates of prescription of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and/or glucagon-like peptide 1 receptor agonists (GLP1-RA) in individuals with type 2 diabetes mellitus (T2DM) with and without chronic kidney disease (CKD)., Research Design and Methods: This was a cross-sectional analyses of SGLT2i and GLP1-RA prescriptions from 1 January 2019 to 31 December 2020 in the Veterans Health Administration System. The likelihood of prescriptions was examined by the presence or absence of CKD and by predicted risks of atherosclerotic cardiovascular disease (ASCVD) and end-stage kidney disease (ESKD)., Results: Of 1,197,880 adults with T2DM, SGLT2i and GLP1-RA were prescribed to 11% and 8% of patients overall, and to 12% and 10% of those with concomitant CKD, respectively. In adjusted models, patients with severe albuminuria were less likely to be prescribed SGLT2i or GLP1-RA versus nonalbuminuric patients with CKD, with odds ratios (ORs) of 0.91 (95% CI 0.89, 0.93) and 0.97 (0.94, 1.00), respectively. Patients with a 10-year ASCVD risk >20% (vs. <5%), had lower odds of SGLT2i use (OR 0.66 [0.61, 0.71]) and GLP1-RA prescription (OR 0.55 [0.52, 0.59]). A 5-year ESKD risk >5%, compared with <1%, was associated with lower likelihood of SGLT2i prescription (OR 0.63 [0.59, 0.67]) but higher likelihood of GLP1-RA prescription (OR 1.53 [1.46, 1.61])., Conclusions: Among a large cohort of patients with T2DM, prescription of SGLT2i and GLP1-RA was low in those with CKD. We observed a "risk-treatment paradox," whereby patients with higher risk of adverse outcomes were less likely to receive these therapies., (© 2022 by the American Diabetes Association.)

Background: In chronic kidney disease (CKD), assessment of both estimated glomerular filtration rate (eGFR) and albuminuria are necessary for stratifying risk and determining the need for nephrology referral. The Kidney Disease: Improving Global Outcomes clinical practice guidelines for CKD recommend nephrology referral for eGFR < 30 ml/min/1.73m 2 or for urinary albumin/creatinine ratio ≥ 300 mg/g., Methods: Using a national claims database of US patients covered by commercial insurance or Medicare Advantage, we identified patients with CKD who were actively followed in primary care. We examined receipt of nephrology care within 1 year among these patients according to their stage of CKD, classified using eGFR and albuminuria categories. Multivariable logistic regression was used to examine odds of receiving nephrology care by CKD category, adjusting for age, sex, race/ethnicity, diabetes, heart failure, and coronary artery disease., Results: Among 291,155 patients with CKD, 55% who met guideline-recommended referral criteria had seen a nephrologist. Receipt of guideline-recommended nephrology care was higher among those with eGFR < 30 (64%; 11,330/17738) compared with UACR ≥300 mg/g (51%; 8789/17290). 59% did not have albuminuria testing. Those patients without albuminuria testing had substantially lower adjusted odds of recommended nephrology care (aOR 0.47 [0.43, 0.52] for eGFR < 30 ml/min/1.73m 2 ). Similar patterns were observed in analyses stratified by diabetes status., Conclusions: Only half of patients meeting laboratory criteria for nephrology referral were seen by a nephrologist. Underutilization of albuminuria testing may be a barrier to identifying primary care patients at elevated kidney failure risk who may warrant nephrology referral., (© 2022. The Author(s).)

For persons with proteinuria, angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs) are treatment mainstays for reducing kidney disease progression. Guidelines for managing hypertension and chronic kidney disease recommend titrating to the maximum ACEi/ARB dose tolerated. Using deidentified national electronic health record data from the Optum Labs Data Warehouse, we examined ACEi/ARB dosing among adults with proteinuria-defined as either a urine albumin to creatinine ratio of 30 mg/g or greater or a protein to creatinine ratio of 150 mg/g or greater-who were prescribed an ACEi/ARB medication between January 1, 2017, and December 31, 2018. Among 100,238 included patients (mean age, 65.1 years; 49,523 [49.4%] female), 29,883 (29.8%) were taking maximal ACEi/ARB doses. Among 74,287 patients without potential contraindications to dose escalation (systolic blood pressure <120 mm Hg, estimated glomerular filtration rate <15 mL/min per 1.73 m 2 , serum potassium level greater than 5.0 mEq/L, or acute kidney injury within the prior year), the frequency of maximal ACEi/ARB dosing was 32.3% (24,025 patients). In adjusted analyses, age less than 40 years, female sex, Hispanic ethnicity, lower urine albumin to creatinine ratio, lack of diabetes, heart failure, lower blood pressure, higher serum potassium level, and prior acute kidney injury were associated with lower odds of maximal ACEi/ARB dosing. Having a prior nephrologist visit was not associated with maximal dosing. Our results suggest that greater attention toward optimizing the dose of ACEi/ARB therapy may represent an opportunity to improve chronic kidney disease care and reduce excess morbidity and mortality associated with disease progression., (Copyright © 2022 Mayo Foundation for Medical Education and Research.

Background: Patient awareness of chronic kidney disease (CKD) is low in part due to suboptimal testing for CKD among those at risk and lack of discussions about kidney disease between patients and clinicians. To bridge these gaps, the National Kidney Foundation developed the Kidney Score Platform, which is a web-based series of tools that includes resources for health care professionals as well as an interactive, dynamic patient-facing component that includes a brief questionnaire about risk factors for kidney disease, individualized assessment of risk for developing CKD, and self-management tools to manage one's kidney disease., Objective: The aim of this study is to perform usability testing of the patient component of the Kidney Score platform among veterans with and at risk for kidney disease and among clinicians working as primary care providers in Veterans Affairs administration., Methods: Think-aloud exercises were conducted, during which participants (veterans and clinicians) engaged with the platform while verbalizing their thoughts and making their perceptions, reasonings, and decision points explicit. A usability facilitator observed participants' behaviors and probed selectively to clarify their comprehension of the tool's instructions, content, and overall functionality. Thematic analysis on the audio-recording transcripts was performed, focusing on positive attributes, negative comments, and areas that required facilitator involvement., Results: Veterans (N=18) were 78% (14/18) male with a mean age of 58.1 years. Two-thirds (12/18) were of non-White race/ethnicity, 28% (5/18) had laboratory evidence of CKD without a formal diagnosis, and 50% (9/18) carried a diagnosis of hypertension or diabetes. Clinicians (N=19) were 29% (5/17) male, 30% (5/17) of non-White race/ethnicity, and had a mean of 17 (range 4-32) years of experience. Veterans and clinicians easily navigated the online tool and appreciated the personalized results page as well as the inclusion of infographics to deliver key educational messages. Three major themes related to content and communication about risk for CKD emerged from the think-aloud exercises: (1) tension between lay and medical terminology when discussing kidney disease and diagnostic tests, (2) importance of linking general information to concrete self-management actions, and (3) usefulness of the tool as an adjunct to the office visit to prepare for patient-clinician communication. Importantly, these themes were consistent among interviews involving both veterans and clinicians., Conclusions: Veterans and clinicians both thought that the Kidney Score Platform would successfully promote communication and discussion about kidney disease in primary care settings. Tension between using medical terminology that is used regularly by clinicians versus lay terminology to promote CKD awareness was a key challenge, and knowledge of this can inform the development of future CKD educational materials., (©Delphine S Tuot, Susan T Crowley, Lois A Katz, Joseph Leung, Delly K Alcantara-Cadillo, Christopher Ruser, Elizabeth Talbot-Montgomery, Joseph A Vassalotti.

Objective: Electronic consultation (eConsult) content reflects important information about referring clinician needs across an organization, but is challenging to extract. The objective of this work was to develop machine learning models for classifying eConsult questions for question type and question content. Another objective of this work was to investigate the ability to solve this task with constrained expert time resources., Materials and Methods: Our data source is the San Francisco Health Network eConsult system, with over 700 000 deidentified questions from the years 2008-2017, from gastroenterology, urology, and neurology specialties. We develop classifiers based on Bidirectional Encoder Representations from Transformers, experimenting with multitask learning to learn when information can be shared across classifiers. We produce learning curves to understand when we may be able to reduce the amount of human labeling required., Results: Multitask learning shows benefits only in the neurology-urology pair where they shared substantial similarities in the distribution of question types. Continued pretraining of models in new domains is highly effective. In the neurology-urology pair, near-peak performance is achieved with only 10% of the urology training data given all of the neurology data., Discussion: Sharing information across classifier types shows little benefit, whereas sharing classifier components across specialties can help if they are similar in the balance of procedural versus cognitive patient care., Conclusion: We can accurately classify eConsult content with enough labeled data, but only in special cases do methods for reducing labeling effort apply. Future work should explore new learning paradigms to further reduce labeling effort., (© The Author(s) 2022.

Importance: Identification of patients with chronic kidney disease (CKD) with high risk of progression to kidney failure can help ensure they receive appropriate and effective nephrology care., Objective: To examine whether patients with CKD at various levels of kidney failure risk receive nephrology care within 1 year of established risk., Design, Setting, and Participants: This population-based, retrospective cohort study collected nationwide administrative health claims data from 156 733 adult patients who met the Kidney Disease: Improving Global Outcomes initiative CKD diagnostic criteria between January 1, 2012, and December 31, 2019, and had an available urine albumin to creatinine ratio within 90 days of a serum creatinine laboratory test. Patients with a history of dialysis or kidney transplant, a prior visit with a nephrologist in the past year, or palliative care billing codes or those who died or disenrolled within 1 year of the albumin to creatinine ratio measurement were excluded. Data analysis was performed from September 10, 2022, to February 14, 2022., Exposures: Kidney failure risk computed with the 5-year Kidney Failure Risk Equation., Main Outcomes and Measures: The main outcome was nephrology care rates across tiers of kidney failure risk, estimated as the proportion of individuals having a nephrologist visit within 1 year after index time., Results: The study population consisted of 156 733 patients with CKD (mean [SD] age, 74.6 [8.4] years; 91 906 [58.6%] female; 86 457 [55.2%] White). A total of 106 004 patients (67.6%) had a low (≤1%) 5-year risk of kidney failure. Nephrology visit rates increased with higher kidney failure risk. Among the 137 highest-risk patients, 79 (57.7%; 95% CI, 48.4%-64.7%) had a nephrology visit. Among 7730 patients with risk above a 10% threshold, 3208 (41.5%; 95% CI, 40.3%-42.4%) had a nephrology visit., Conclusions and Relevance: This study's findings suggest that nearly half of patients with CKD at high risk of progressing to kidney failure do not have a nephrologist visit within 1 year of established risk. These findings have implications in the design of risk-based guidelines for referral and in the practice of delivering nephrology care to patients with CKD.

Objective: During COVID-19, otolaryngology clinics rapidly implemented telehealth programs in accordance with social distancing guidelines and institutional policies. Our objectives are to evaluate the usefulness of telephone audio visits for underserved patients seeking otolaryngological care at an urban safety-net hospital and identify patient factors associated with telephone visit attendance., Methods: In a retrospective review of all adult telephone visits in 2020, we compared the demographics and visit characteristics of patients who attended telehealth versus in-person visits and patients who attended versus missed telehealth visits. Univariable and multivariable regressions were utilized to identify predictors of missing telehealth visits., Results: We identified 318 telehealth encounters completed by 254 patients (72.8% were of racial/ethnic minority; 76.3% had low-income, need-based insurances; 43.7% had limited English proficiency). The most common chief complaints were related to head and neck oncology ( n  = 85, 26.7%), otology/neurotology ( n  = 74, 23.3%), and general otolaryngology ( n  = 69, 21.7%). The following actions were executed during telephone visits: behavioral and/or medication patient education ( n  = 152, 47.8%); sharing testing/imaging/tumor board results ( n  = 125, 39.3%); referrals to another department ( n  = 103, 32.4%); rendering a new diagnosis ( n  = 98, 30.8%); changing medications ( n  = 60, 18.9%). Less than half of telephone visits (46.2%) resulted in in-person follow-up, most commonly for in-person exams. The distribution of race/ethnicity differed between attended in-person appointments versus telephone visits ( p  = .01), but race and ethnicity were not significant predictors of telephone visit attendance., Conclusion: Despite limited diagnostic capabilities, telephone audio visits can be an effective and accessible tool for providing continuity and advancing care in socially disadvantaged patients., Level of Evidence: IV., Competing Interests: Dr. Jeffrey D.

Rationale & Objective: Equations for estimated glomerular filtration rate (eGFR) that incorporate a term for race assign a higher value to Black individuals compared to non-Black individuals for the same sex, age, and serum creatinine concentration. This difference may contribute to racial disparities in kidney transplant access. We sought to (1) compare time from meeting a transplant eligibility threshold of eGFR ≤20 mL/min/1.73 m 2 to kidney failure with replacement therapy (KFRT) among Black, Hispanic, and White patients, and (2) assess the impact of incorporation of race into eGFR expressions on establishment of waitlist eligibility and time from eligibility to KFRT., Study Design: Retrospective cohort., Setting & Participants: Using the OptumLabs Data Warehouse, we assembled a cohort of 40,042 White, 8,519 Black, and 3,569 Hispanic patients having at least one eGFR value between 20 and 60 mL/min/1.73 m 2 within the preceding 2 years and an incident outpatient eGFR of ≤20 mL/min/1.73 m 2 between 2008-2018, using the CKD-EPI creatinine equation that includes a term for race coded as Black or non-Black. We then reassembled a Black patient cohort based on incident eGFR ≤20 mL/min/1.73 m 2 (n = 11,269) estimated using the same CKD-EPI equation but coding Black patients as non-Black., Exposure: Race/ethnicity., Outcome: Time to KFRT., Analytical Approach: Unadjusted and adjusted Fine-Gray models; linear regression to compute eGFR slopes., Results: By 3 years, the cumulative incidence of KFRT was 20.5% among White patients, 40.9% among Hispanic patients, 36% among Black patients whose GFR was estimated using a race term coded as Black, and 28.7% among Black patients whose GFR was estimated using a race term coded as non-Black. In fully adjusted analyses including 11,269 Black patients with an eGFR ≤20 mL/min/1.73 m 2 based on coding them as non-Black, KFRT risk remained greater among Black (HR, 1.28 [95% CI, 1.15-1.43]) and Hispanic (HR, 1.66 [95% CI, 1.18-2.31]) patients than among White patients. Based on slopes of eGFR decline, coding Black patients as non-Black would allow earlier waitlist activation by an estimated median of 0.5 [interquartile range, 0.27-1.23] years., Limitations: Inability to exclude individuals who would not be kidney transplant candidates if comprehensively evaluated., Conclusions: A uniform eGFR threshold provides less opportunity for being placed on the transplant waitlist among Black and Hispanic patients. For many Black patients, estimation of GFR as if their race category were non-Black would allow substantially earlier waitlisting but would not eliminate their shorter time to KFRT and reduced opportunity for preemptive transplantation compared with White patients., (Copyright © 2021 National Kidney Foundation, Inc.

Background: Studies report higher diagnostic accuracy using the collective intelligence (CI) of multiple clinicians compared with individual clinicians. However, the diagnostic process is iterative, and unexplored is the value of CI in improving clinical recommendations leading to a final diagnosis., Methods: To compare the appropriateness of diagnostic recommendations advised by individual physicians versus the CI of physicians, we entered actual consultation requests sent by primary care physicians to specialists onto a web-based CI platform capable of collecting diagnostic recommendations (next steps for care) from multiple physicians. We solicited responses to 35 cases (12 endocrinology, 13 gynecology, 10 neurology) from ≥3 physicians of any specialty through the CI platform, which aggregated responses into a CI output. The primary outcome was the appropriateness of individual physician recommendations versus the CI output recommendations, using recommendations agreed upon by 2 specialists in the same specialty as a gold standard. The secondary outcome was the recommendations' potential for harm., Results: A total of 177 physicians responded. Cases had a median of 7 respondents (interquartile range: 5-10). Diagnostic recommendations in the CI output achieved higher levels of appropriateness (69%) than recommendations from individual physicians (45%; χ 2 = 5.95, P = 0.015). Of the CI recommendations, 54% were potentially harmful, as compared with 41% of individuals' recommendations (χ 2 = 2.49, P = 0.11)., Limitations: Cases were from a single institution. CI was solicited using a single algorithm/platform., Conclusions: When seeking specialist guidance, diagnostic recommendations from the CI of multiple physicians are more appropriate than recommendations from most individual physicians, measured against specialist recommendations. Although CI provides useful recommendations, some have potential for harm. Future research should explore how to use CI to improve diagnosis while limiting harm from inappropriate tests/therapies.

Background: The COVID-19 pandemic prompted safety-net health care systems to rapidly implement telemedicine services with little prior experience, causing disparities in access to virtual visits. While much attention has been given to patient barriers, less is known regarding system-level factors influencing telephone versus video-visit adoption. As telemedicine remains a preferred service for patients and providers, and reimbursement parity will not continue for audio visits, health systems must evaluate how to support higher-quality video visit access., Objective: This study aimed to assess health system-level factors and their impact on telephone and video visit adoption to inform sustainability of telemedicine for ambulatory safety-net sites., Methods: We conducted a cross-sectional survey among ambulatory care clinicians at a hospital-linked ambulatory clinic network serving a diverse, publicly insured patient population between May 28 and July 14, 2020. We conducted bivariate analyses assessing health care system-level factors associated with (1) high telephone adoption (4 or more visits on average per session); and (2) video visit adoption (at least 1 video visit on average per session)., Results: We collected 311 responses from 643 eligible clinicians, yielding a response rate of 48.4%. Clinician respondents (N=311) included 34.7% (n=108) primary or urgent care, 35.1% (n=109) medical, and 7.4% (n=23) surgical specialties. Our sample included 178 (57.2%) high telephone adopters and 81 (26.05%) video adopters. Among high telephone adopters, 72.2% utilized personal devices for telemedicine (vs 59.0% of low telephone adopters, P=.04). Video nonadopters requested more training in technical aspects than adopters (49.6% vs 27.2%, P<.001). Primary or urgent care had the highest proportion of high telephone adoption (84.3%, compared to 50.4% of medical and 37.5% of surgical specialties, P<.001). Medical specialties had the highest proportion of video adoption (39.1%, compared to 14.8% of primary care and 12.5% of surgical specialties, P<.001)., Conclusions: Personal device access and department specialty were major factors associated with high telephone and video visit adoption among safety-net clinicians. Desire for training was associated with lower video visit use. Secure device access, clinician technical trainings, and department-wide assessments are priorities for safety-net systems implementing telemedicine., (©Anjana E Sharma, Elaine C Khoong, Maribel Sierra, Natalie A Rivadeneira, Malini A Nijagal, George Su, Courtney R Lyles, Triveni DeFries, Delphine S Tuot, Urmimala Sarkar.

Rationale & Objective: Black kidney transplant recipients have higher prevalences of cardiovascular disease (CVD) risk factors and less intensive risk factor control than White kidney transplant recipients. Our objective was to evaluate racial disparities in receipt of statins and aspirin for secondary CVD prevention among kidney transplant recipients in the Folic Acid for Vascular Outcome Reduction in Transplantation (FAVORIT) trial., Study Design: Cohort study., Setting & Participants: FAVORIT participants of White, Black, and Other races from the United States and Canada with a history of CVD at study entry or who experienced a nonfatal CVD event during follow-up., Predictor: Race., Outcome: Receipt of statins and aspirin for secondary CVD prevention., Analytical Approach: We used parametric (Weibull), proportional-hazards, interval-censored survival models to evaluate the independent association of race with receipt of statins and aspirin for secondary CVD prevention., Results: Of the 4,110 kidney transplant recipients enrolled in FAVORIT trial, 978 met the inclusion criteria (78% White, 17% Black, and 6% Other race). Compared with the White race, Black and Other races were associated with lower hazards of receiving statins (Black race: adjusted HR, 0.76 [95% CI, 0.60-0.97]; Other race: adjusted HR, 0.87 [95% CI, 0.60-1.27]) and aspirin (Black race: adjusted HR, 0.85 [95% CI, 0.67-1.08]; Other race: adjusted HR, 0.63 [95% CI, 0.43-0.94])., Limitations: Lack of granular information on potential indications or contraindications for aspirin or statin use for secondary CVD prevention., Conclusions: Post hoc findings from the FAVORIT trial demonstrated that Black race was associated with a lower likelihood of receiving statins and Other race was associated with a lower likelihood of receiving aspirin for secondary CVD prevention. This represents a potential target to improve CVD care in non-White kidney transplant recipients., (© 2022 The Authors.)

Religion and related institutions have resources to help individuals cope with chronic conditions, such as chronic kidney disease (CKD). The purpose of this investigation is to examine the association between religious service attendance and mortality for adults with CKD. Data were drawn from NHANES III linked to the 2015 public use Mortality File to analyze a sample of adults ( n = 3558) who had CKD as defined by a single value of estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m 2 using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and/or albumin-to-creatinine ratio ≥17 mg/g for males or ≥25 for females. All-cause mortality was the primary outcome and religious service attendance was the primary independent variable. Cox proportional hazards models were estimated to determine the association between religious service attendance and mortality. The mortality risks for participants who attended a service at least once per week were 21% lower than their peers with CKD who did not attend a religious service at all (HR 0.79; CI 0.64-0.98). The association between religious service attendance and mortality in adults with CKD suggest that prospective studies are needed to examine the influence of faith-related behaviors on clinical outcomes in patients with CKD.

Background: Neighborhood social cohesion (NSC) is the network of relationships as well as the shared values and norms of residents in a neighborhood. Higher NSC has been associated with improved cardiovascular health, largely among Whites but not African Americans. In a bi-racial cohort, we aimed to study the association between NSC and chronic disease awareness and engagement in healthy self-management behaviors, two potential mechanisms by which NSC could impact cardiovascular health outcomes., Methods: Using the Healthy Aging in Neighborhoods of Diversity Across the Lifespan Study (HANDLS), we cross-sectionally examined the association between NSC and awareness of three chronic conditions (diabetes, chronic kidney disease (CKD), and hypertension) and engagement in healthy self-management behaviors including physical activity, healthy eating, and cigarette avoidance., Results: Study participants (n = 2082) had a mean age of 56.5 years; 38.7% were White and 61.4% African American. Of the participants, 26% had diabetes, 70% had hypertension and 20.2% had CKD. Mean NSC was 3.3 (SD = 0.80) on a scale of 1 (lowest score) to 5 (highest score). There was no significant association between NSC and any chronic disease awareness, overall or by race. However, each higher point in mean NSC score was associated with less cigarette use and healthier eating scores, among Whites (adjusted odds ratio [aOR], 95% confidence interval [CI]: =0.76, 0.61-0.94; beta coefficient [βc]:, 95% CI: 1.75; 0.55-2.97, respectively) but not African Americans (aOR = 0.95, 0.79-1.13; βc: 0.46, - 0.48-1.39, respectively; P interaction  = 0.08 and 0.06). Among both Whites and African Americans, higher NSC scores were associated with increases in self-reported physical activity (βc: 0.12; 0.08-0.16; P interaction  = 0.40)., Conclusions: Community engagement and neighborhood social cohesion may be important targets for promotion of healthy behaviors and cardiovascular disease prevention. More research is needed to understand the different associations of NSC and healthy behaviors by race., (© 2021. The Author(s).)

Importance: Significant racial and ethnic disparities in chronic kidney disease (CKD) progression and outcomes are well documented, as is low use of guideline-recommended CKD care., Objective: To examine guideline-recommended CKD care delivery by race and ethnicity in a large, diverse population., Design, Setting, and Participants: In this serial cross-sectional study, adult patients with CKD that did not require dialysis, defined as a persistent estimated glomerular filtration rate less than 60 mL/min/1.73 m2 or a urine albumin-creatinine ratio of 30 mg/g or higher for at least 90 days, were identified in 2-year cross-sections from January 1, 2012, to December 31, 2019. Data from the OptumLabs Data Warehouse, a national data set of administrative and electronic health record data for commercially insured and Medicare Advantage patients, were used., Exposures: The independent variables were race and ethnicity, as reported in linked electronic health records., Main Outcomes and Measures: On the basis of guideline-recommended CKD care, the study examined care delivery process measures (angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker prescription for albuminuria, statin prescription, albuminuria testing, nephrology care for CKD stage 4 or higher, and avoidance of chronic nonsteroidal anti-inflammatory drug prescription) and care delivery outcome measures (blood pressure and diabetes control)., Results: A total of 452 238 patients met the inclusion criteria (mean [SD] age, 74.0 [10.2] years; 262 089 [58.0%] female; a total of 7573 [1.7%] Asian, 49 970 [11.0%] Black, 15 540 [3.4%] Hispanic, and 379 155 [83.8%] White). Performance on process measures was higher among Asian, Black, and Hispanic patients compared with White patients for angiotensin-converting enzyme inhibitor and angiotensin II receptor blocker use (79.8% for Asian patients, 76.7% for Black patients, and 79.9% for Hispanic patients compared with 72.3% for White patients in 2018-2019), statin use (72.6% for Asian patients, 69.1% for Black patients, and 74.1% for Hispanic patients compared with 61.5% for White patients), nephrology care (64.8% for Asian patients, 72.9% for Black patients, and 69.4% for Hispanic patients compared with 58.3% for White patients), and albuminuria testing (53.9% for Asian patients, 41.0% for Black patients, and 52.6% for Hispanic patients compared with 30.7% for White patients). Achievement of blood pressure control to less than 140/90 mm Hg was similar or lower among Asian (71.8%), Black (63.3%), and Hispanic (69.8%) patients compared with White patients (72.9%). Achievement of diabetes control with hemoglobin A1c less than 7.0% was 50.1% in Asian patients, 49.3% in Black patients, and 46.0% in Hispanic patients compared with 50.3% for White patients., Conclusions and Relevance: Higher performance on CKD care process measures among Asian, Black, and Hispanic patients suggests that differences in medication prescription and diagnostic testing are unlikely to fully explain known disparities in CKD progression and kidney failure. Improving care delivery processes alone may be inadequate for reducing these disparities.

It is unclear whether previously developed frameworks for effective consultation apply to requests initiated by alphanumeric text page. We assessed a random sample of 210 text paged consult requests for communication of previously described 'essential elements' for effective consultation: reason for consult, level of urgency and requester contact information. Overall page quality was evaluated on a 5-point Likert scale. Over 90% of text paged consult requests included contact information and reason for consult; 14% indicated level of urgency. In ordinal logistic regression, reason for consult was most strongly associated with quality (OR 22.4; 95% CI 8.1 to 61.7), followed by callback number (OR 6.2; 95% CI 0.8 to 49.5), caller's name (OR 5.0; 95% CI 1.9 to 13.1) and level of urgency (OR 3.3; 95% CI 1.6 to 6.7). Results suggest that text paged consult requests often include most informational elements, and that urgency, often missing, may not be as 'essential' for text pages as it was once thought to be., Competing Interests: Competing interests: Dr Khanna helped develop CareWeb, which has been licensed by Voalte.

Rationale & Objective: Patient awareness of disease is the first step toward effective management and disease control. Awareness of chronic kidney disease (CKD) has consistently been shown to be low, but studies estimating patient awareness of CKD have used different methods. We sought to determine whether the estimated prevalence of CKD awareness differed by the wording used to ascertain awareness or by setting characteristics., Study Design: Systematic review and meta-analysis., Setting & Study Populations: Adults with CKD not receiving dialysis., Selection Criteria for Studies: We included studies that estimated CKD awareness, determined CKD status by laboratory criteria, and provided the exact question wording used to ascertain awareness., Data Extraction: 2 reviewers independently extracted data for each study; discordance was resolved by a third independent reviewer., Analytical Approach: Mixed-effects models were used to calculate pooled CKD awareness estimates and 95% CIs., Results: 32 studies were included. Publication year ranged from 2004 to 2017, with study populations ranging from 107 to 28,923 individuals. CKD awareness in individual studies ranged from 0.9% to 94.0%. Pooled CKD awareness was 19.2% (95% CI, 10.0%-33.6%) overall and was 26.5% (95% CI, 11.9%-48.9%) among individuals with an estimated glomerular filtration rate < 60 mL/min/1.73 m 2 . "Kidney problem" was the most sensitive question for CKD awareness (58.7%; 95% CI, 32.4%-80.8%); "weak or failing kidneys" was the least sensitive (12.3%; 95% CI, 4.5%-29.4%). CKD awareness was highest among patients from nephrology practices (86.2%; 95% CI, 74.9%-93.0%) and lowest in the general population (7.3%; 95% CI, 5.0%-10.5%)., Limitations: Significant heterogeneity across studies overall and among examined subgroups of wording and study setting., Conclusions: Differently worded questions may lead to widely different estimates of CKD awareness. Consistent terminology is likely needed to most effectively surveil and leverage CKD awareness to improve management and disease control., (© 2021 The Authors.)

Since 2003, US hypertension guidelines have recommended ACE (angiotensin-converting enzyme) inhibitors or ARBs (angiotensin receptor blockers) as first-line antihypertensive therapy in the presence of albuminuria (urine albumin/creatinine ratio ≥300 mg/g). To examine national trends in guideline-concordant ACE inhibitor/ARB utilization, we studied adults participating in the National Health and Nutrition Examination Surveys 2001 to 2018 with hypertension (defined by self-report of high blood pressure, systolic blood pressure ≥140 mm Hg or diastolic ≥90 mm Hg, or use of antihypertensive medications). Among 20 538 included adults, the prevalence of albuminuria ≥300 mg/g was 2.8% in 2001 to 2006, 2.8% in 2007 to 2012, and 3.2% in 2013 to 2018. Among those with albuminuria ≥300 mg/g, no consistent trends were observed for the proportion receiving ACE inhibitor/ARB treatment from 2001 to 2018 among persons with diabetes, without diabetes, or overall. In 2013 to 2018, ACE inhibitor/ARB usage in the setting of albuminuria ≥300 mg/g was 55.3% (95% CI, 46.8%-63.6%) among adults with diabetes and 33.4% (95% CI, 23.1%-45.5%) among those without diabetes. Based on US population counts, these estimates represent 1.6 million adults with albuminuria ≥300 mg/g currently not receiving ACE inhibitor/ARB therapy, nearly half of whom do not have diabetes. ACE inhibitor/ARB underutilization represents a significant gap in preventive care delivery for adults with hypertension and albuminuria that has not substantially changed over time.

Background: Patient awareness of CKD and primary care provider (PCP) recognition of CKD are lower than for other chronic conditions. Understanding how patients may become aware of CKD is critical to their participation in healthy behaviors to slow CKD progression. We examined factors associated with the concordance of CKD awareness among patients and providers and hypothesized that concordance of CKD awareness would be influenced by social and demographic factors that impact communication, such as limited English proficiency (LEP) and health literacy., Methods: Between July 2011 to July 2014, patients with CKD from three primary care clinics in a public healthcare delivery system were surveyed with questions regarding their health, including awareness of their CKD status. Chart review was performed to identify PCP recognition of CKD, defined as CKD listed anywhere in the problem list within nine months before patient enrollment into the study. We used logistic regression to determine the association between provider recognition and patient awareness of kidney disease among those patients with CKD, adjusting for patient demographics, co-morbidities, and provider training., Results: The study population (n = 152) had a mean age of 57.4 (SD 13), was 48.7% male and was racially/ethnically and linguistically diverse: 89.5% self-identified as Black, Hispanic, or Asian and 32.2% had LEP. Most patients had hypertension (89.5%) and diabetes (77.6%); mean eGFR was 66.1 ml/min/1.73m 2 (SD 32.8). Positive concordance of CKD awareness was 42% (n = 64). Odds of positive concordance with their providers were much higher among patients with LEP compared to English speaking patients (adjusted odds ratio = 11.07, 95%CI 1.60-76.39)., Conclusions: Concordance of CKD awareness among PCPs and their patients with CKD in one public delivery system was higher among patients with LEP. While speculative, this may be due to greater caution in provider communication about CKD with LEP patients.

Importance: There are concerns with translating results from the Systolic Blood Pressure Intervention Trial (SPRINT) into clinical practice because the standardized protocol used to measure blood pressure (BP) may not be consistently applied in routine clinical practice., Objectives: To evaluate the concordance between BPs obtained in routine clinical practice and those obtained using the SPRINT protocol and whether concordance varied by target trial BP., Design, Setting, and Participants: This observational prognostic study linking outpatient vital sign information from electronic health records (EHRs) with data from 49 of the 102 SPRINT sites was conducted from November 8, 2010, to August 20, 2015, among 3074 adults 50 years or older with hypertension without diabetes or a history of stroke. Statistical analysis was performed from May 21, 2019, to March 20, 2020., Main Outcomes and Measures: Blood pressures measured in routine clinical practice and SPRINT., Results: Participant-level EHR data was obtained for 3074 participants (2482 men [80.7%]; mean [SD] age, 68.5 [9.1] years) with 3 or more outpatient and trial BP measurements. In the period from the 6-month study visit to the end of the study intervention, the mean systolic BP (SBP) in the intensive treatment group from outpatient BP recorded in the EHR was 7.3 mm Hg higher (95% CI, 7.0-7.6 mm Hg) than BP measured at trial visits; the mean difference between BP recorded in the outpatient EHR and trial SBP was smaller for participants in the standard treatment group (4.6 mm Hg [95% CI, 4.4-4.9 mm Hg]). Bland-Altman analyses demonstrated low agreement between outpatient BP recorded in the EHR and trial BP, with wide agreement intervals ranging from approximately -30 mm Hg to 45 mm Hg in both treatment groups. In addition, the difference between BP recorded in the EHR and trial BP varied widely by site., Conclusions and Relevance: Outpatient BPs measured in routine clinical practice were generally higher than BP measurements taken in SPRINT, with greater mean SBP differences apparent in the intensive treatment group. There was a consistent high degree of heterogeneity between the BPs recorded in the EHR and trial BPs, with significant variability over time, between and within the participants, and across clinic sites. These results highlight the importance of proper BP measurement technique and an inability to apply 1 common correction factor (ie, approximately 10 mm Hg) to approximate research-quality BP estimates when BP is not measured appropriately in routine clinical practice., Trial Registration: SPRINT ClinicalTrials.gov Identifier: NCT01206062.

Rationale & Objective: The Kidney Failure Risk Equation (KFRE) is a simple widely validated prediction model using age, sex, estimated glomerular filtration rate, and urinary albumin-creatinine ratio to predict the risk for end-stage kidney disease. Data are limited for its applicability to kidney transplant recipients., Study Design: Validation study of the KFRE as a post hoc analysis of the Folic Acid for Vascular Outcomes Reduction in Transplantation (FAVORIT) Trial., Setting & Participants: Adult kidney transplant recipients with functioning kidney allografts at least 6 months posttransplantation from 30 centers in the United States, Canada, and Brazil. Participants with estimated glomerular filtration rates < 60 mL/min/1.73 m 2 at study entry were included., Predictor: 2- and 5-year kidney failure risk predicted by the KFRE using variables at study entry., Outcome: Graft loss, defined by initiation of dialysis., Analytical Approach: Discrimination of the KFRE was assessed using C statistics; calibration was assessed by plotting predicted risk against observed cumulative incidence of graft loss., Results: 2,889 participants were included. Within 2 years, 98 participants developed graft loss, 107 participants died with a functioning graft, and 129 participants were lost to follow-up, and by 5 years, 252 had developed graft loss, 265 died with a functioning graft, and 1,543 were lost to follow-up. The KFRE demonstrated accurate calibration and discrimination (C statistic, 0.85 [95% CI, 0.81-0.88] at 2 years and 0.81 [95% CI, 0.78-0.84] at 5 years); performance was similar regardless of donor type (living vs deceased) and graft vintage, with the noted exception of poorer calibration for graft vintage less than 2 years., Limitations: Unavailable cause of graft loss., Conclusions: The KFRE accurately predicted the risk for graft loss among adult kidney transplant recipients with graft vintage longer than 2 years and may be a useful prognostic tool for nephrologists caring for kidney transplant recipients., (© 2020 The Authors.)

Background: Patient awareness, clinician detection, and management of chronic kidney disease remain suboptimal, despite clinical practice guidelines and diverse education programs., Objective: This protocol describes a study to develop and investigate the impact of the National Kidney Foundation Kidney Score Platform on chronic kidney disease awareness, communication, and management, by leveraging the Behavior Change Wheel, an implementation science framework that helps identify behavioral intervention targets and functions that address barriers to behavior change., Methods: We interviewed 20 patients with chronic kidney disease and 11 clinicians to identify patient and clinician behaviors suitable for intervention and barriers to behavior change (eg, limited awareness of chronic kidney disease clinical practice guidelines within primary care settings, limited data analytics to highlight chronic kidney disease care gaps, asymptomatic nature of chronic kidney disease in conjunction with patient reliance on primary care clinicians to determine risk and order kidney testing). Leveraging the Behavior Change Wheel, the Kidney Score Platform was developed with a patient-facing online Risk Calculator and a clinician-facing Clinical Practice Toolkit. The Risk Calculator utilizes risk predictive analytics to provide interactive health information tailored to an individual's chronic kidney disease risk and health status. The Clinical Practice Toolkit assists clinicians in discussing chronic kidney disease with individuals at risk for and with kidney disease and in managing their patient population with chronic kidney disease. The Kidney Score Platform will be tested in 2 Veterans Affairs primary health care settings using a pre-post study design. Outcomes will include changes in patient self-efficacy for chronic kidney disease management (primary outcome), quality of communication with clinicians about chronic kidney disease, and practitioners' knowledge of chronic kidney disease guidelines. Process outcomes will identify usability and adoption of different elements of the Kidney Score Platform using qualitative and quantitative methods., Results: As of September 2020, usability studies are underway with veterans and clinicians to refine the patient-facing components of the Kidney Score Platform before study initiation. Results and subsequent changes to the Kidney Score Platform will be published at a later date. The study is expected to be completed by December 2021., Conclusions: Results of this study will be used to inform integration of the Kidney Score Platform within primary care settings so that it can serve as a central component of the National Kidney Foundation public awareness campaign to educate, engage, and empower individuals at risk for and living with chronic kidney disease., International Registered Report Identifier (irrid): PRR1-10.2196/22024., (©Delphine S Tuot, Susan T Crowley, Lois A Katz, Joseph Leung, Delly K Alcantara-Cadillo, Christopher Ruser, Elizabeth Talbot-Montgomery, Joseph A Vassalotti.

Rationale & Objective: Persons with chronic kidney disease (CKD) are often unaware of their disease status. Efforts to improve CKD awareness may be most effective if focused on persons at highest risk for progression to kidney failure., Study Design: Serial cross-sectional surveys., Setting & Participants: Nonpregnant adults (aged≥20 years) with CKD glomerular filtration rate categories 3-4 (G3-G4) who participated in the National Health and Nutrition Examination Survey from 1999 to 2016 (n = 3,713)., Predictor: 5-year kidney failure risk, estimated using the Kidney Failure Risk Equation. Predicted risk was categorized as minimal (<2%), low (2%-<5%), intermediate (5%-<15%), or high (≥15%)., Outcome: CKD awareness, defined by answering "yes" to the question "Have you ever been told by a doctor or other health professional that you had weak or failing kidneys?", Analytical Approach: Prevalence of CKD awareness was estimated within each risk group using complex sample survey methods. Associations between Kidney Failure Risk Equation risk and CKD awareness were assessed using multivariable logistic regression. CKD awareness was compared with awareness of hypertension and diabetes during the same period., Results: In 2011 to 2016, unadjusted CKD awareness was 9.6%, 22.6%, 44.7%, and 49.0% in the minimal-, low-, intermediate-, and high-risk groups, respectively. In adjusted analyses, these proportions did not change over time. Awareness of CKD, including among the highest risk group, remains consistently below that of hypertension and diabetes and awareness of these conditions increased over time., Limitations: Imperfect sensitivity of the "weak or failing kidneys" question for ascertaining CKD awareness., Conclusions: Among adults with CKD G3-G4 who have 5-year estimated risks for kidney failure of 5%-<15% and≥15%, approximately half were unaware of their kidney disease, a gap that has persisted nearly 2 decades., (Copyright © 2020 National Kidney Foundation, Inc.

Background: Expanding healthcare innovations from the local to national level is a complex pursuit requiring careful assessment of all relevant factors. In this study (a component of a larger eConsult programme of research), we aimed to identify the key factors involved in the spread and scale-up of a successful regional eConsult model across Canada., Methods: We conducted a constant comparative thematic analysis of stakeholder discussions captured during a full-day National eConsult Forum meeting held in Ottawa, Canada, on 11 December 2017. Sixty-four participants attended, representing provincial and territorial governments, national organisations, healthcare providers, researchers and patients. Proceedings were recorded, transcribed and underwent qualitative analysis using the Framework for Applied Policy Research., Results: This study identified four main themes that were critical to support the intentional efforts to spread and scale-up eConsult across Canada, namely (1) identifying population care needs and access problems, (2) engaging stakeholders who were willing to roll up their sleeves and take action, (3) building on current strategies and policies, and (4) measuring and communicating outcomes., Conclusions: Efforts to promote innovation in healthcare are more likely to succeed if they are based on an understanding of the forces that drive the spread and scale-up of innovation. Further research is needed to develop and strengthen the conceptual and applied foundations of the spread and scale-up of healthcare innovations, especially in the context of emergent learning health systems across Canada and beyond.

Objectives: Electronic consultation, or e-consult, systems improve specialty care access by conveying specialist expertise to primary care clinicians (PCCs) without requiring specialist visits. Our study evaluates organizational factors for e-consult implementation across 5 publicly financed, county-based health systems in California. Each system serves 40,000 to 180,000 culturally and linguistically diverse patients across 4 to 19 primary care locations., Study Design: We interviewed leaders whose systems received grant funding between 2015 and 2017 to plan and implement e-consult. Interviews discussed platform selection, electronic health record (EHR) compatibility, PCC and specialist opinions, and project governance. We also collected implementing systems' platform operations metrics., Methods: Mixed methods, including semistructured interviews and quantitative platform metrics. Interviews were analyzed in alignment with the Consolidated Framework for Implementation Research inner setting domain., Results: Three of the 5 systems successfully implemented e-consults. System 1 sustained implementation across 27 specialties, system 2 achieved fragmented implementation, and system 3 reported early-stage implementation. Existing PCC-specialist relationships emerged as the strongest facilitator. E-consult-EHR technology integration was also important, although an add-on platform enabled e-consult expansion in system 2. Although all systems faced challenges, such as project management resourcing, systems 4 and 5 abandoned implementation amid compound climate and readiness barriers., Conclusions: Successful e-consult implementations in public delivery systems leveraged (1) prior primary care and specialty care clinician relationships and (2) integrated EHR and e-consult platforms. This contrasts with common expectations that new technology will overcome care delivery gaps. Findings add to existing e-consult implementation literature that emphasizes reimbursement and leadership champions.
