Use of the kidney failure risk equation to inform clinical care of patients with chronic kidney disease: a mixed-methods systematic review.

ABSTRACT:

Rationale and objective

The Kidney Failure Risk Equation (KFRE) predicts the risk of end-stage kidney disease in patients with chronic kidney disease (CKD). This study aimed to evaluate the impact of the utility of KFRE in clinical practice.

Study design

Systematic review.

Setting and study populations

Adult patients with CKD but not receiving renal replacement therapy enrolled in studies where KFRE was used in clinical care pathways.

Selection criteria for studies

All studies published from April 2011 to October 2021 identified from Medline, Cumulative Index to Nursing and Allied Health Literature, Embase and reference and citation searches of included studies.

Data extraction

Relevant data were extracted, and two reviewers independently assessed study quality using appropriate appraisal tools.

Analytical approach

Findings reported as a narrative synthesis due to heterogeneity of the included studies.

Results

Of 1635 studies identified, 440 duplicates were removed. The remaining 1195 titles and abstracts were screened. All five studies for full-text review were included in the analysis. Three uses of KFRE were assessed: (1) primary to specialty care interface; (2) general nephrology to multidisciplinary care transition; and (3) treatment planning. Evidence of impact on number of patient referrals into nephrology care was conflicting. However, wait times improved in one study. Although KFRE identified high-risk patients for increased multidisciplinary support, there was concern patients stepped down, no longer meeting eligibility criteria, may lack access to services.

Conclusions

This is the first systematic review of studies that have assessed the actual impact of KFRE in clinical practice with five studies of varying quality reported to date. Trials are in progress assessing the impact on clinical outcomes of using KFRE in clinical practice, and KFRE is being incorporated into guidelines for CKD management. Further studies are needed to assess the impact of KFRE on clinical care.

Project description:Background and objectivesPatients with CKD exhibit heterogeneity in their rates of progression to kidney failure. The kidney failure risk equation (KFRE) has been shown to accurately estimate progression to kidney failure in adults with CKD. Our objective was to determine health care utilization patterns of patients on the basis of their risk of progression.Design, setting, participants, & measurementsWe conducted a retrospective cohort study of adults with CKD and eGFR of 15-59 ml/min per 1.73 m2 enrolled in multidisciplinary CKD clinics in the province of Saskatchewan, Canada. Data were collected from January 1, 2004 to December 31, 2012 and followed for 5 years (December 31, 2017). We stratified patients by eGFR and risk of progression and compared the number and cost of hospital admissions, physician visits, and prescription drugs.ResultsIn total, 1003 adults were included in the study. Within the eGFR of 15-29 ml/min per 1.73 m2 group, the costs of hospital admissions, physician visits, and drug dispensations over the 5-year study period comparing high-risk patients with low-risk patients were (Canadian dollars) $89,265 versus $48,374 (P=0.008), $23,423 versus $11,231 (P<0.001), and $21,853 versus $16,757 (P=0.01), respectively. Within the eGFR of 30-59 ml/min per 1.73 m2 group, the costs of hospital admissions, physician visits, and prescription drugs were $55,944 versus $36,740 (P=0.10), $13,414 versus $10,370 (P=0.08), and $20,394 versus $14,902 (P=0.02) in high-risk patients in comparison with low-risk patients, respectively, for progression to kidney failure.ConclusionsIn patients with CKD and eGFR of 15-59 ml/min per 1.73 m2 followed in multidisciplinary clinics, the costs of hospital admissions, physician visits, and drugs were higher for patients at higher risk of progression to kidney failure by the KFRE compared with patients in the low-risk category. The high-risk group of patients with CKD and eGFR of 15-29 ml/min per 1.73 m2 had stronger association with hospitalizations costs, physician visits, and drug utilizations.

Project description:BackgroundOlder people with kidney failure often choose conservative kidney care. The experiences and quality of life (QOL) of caregivers who support them are incompletely characterized.ObjectiveTo determine the burden, QOL, and understand experiences of caregivers supporting patients managed conservatively.DesignSystematic review of quantitative and qualitative studies.Sources of informationPubMed, Embase, PsycINFO, CINAHL, and MEDLINE electronic databases were systematically searched for quantitative and qualitative studies published between January 2000 and July 2020.SubjectsCaregivers of adults with kidney failure (estimated glomerular filtration rate < 15 mL/min/1.73 m2) managed conservatively.MethodsData were extracted by 2 independent reviewers using a prespecified extraction tool. Study quality was assessed using the Critical Appraisal Skills Program (CASP) tool.MeasurementsDescriptive reports of demographics, measurement scales, and outcomes. Thematic synthesis of qualitative data.ResultsSix studies met inclusion criteria, including 3 quantitative and 3 descriptive qualitative studies. Caregivers of patients receiving conservative kidney management (CKM) experienced significant caregiver burden and similar impacts to their QOL as those caring for patients receiving dialysis. Thematic synthesis revealed 5 themes: Understanding the concept of CKM, Need for involvement in the decision for CKM, Identifying available supports, Uncertainty about the future and negotiating deteriorations and dying, and Burden of care impacting on QOL.LimitationsLow numbers of included studies, data collection and recruitment biases in qualitative studies and small caregiver numbers in quantitative studies, limit transferability of findings. Heterogeneity in study design and outcome measures precluded meta-analysis.ConclusionsCaregivers of patients with conservatively managed kidney failure suffer significant burden and experience QOL comparable with those caring for patients on dialysis. Limited understanding and involvement in conservative management decision making, and a fear of deterioration and dying, result in anxiety in caregivers. Further research into the experiences of caregivers will help support both caregivers and the patients who choose conservative management.RegistrationPROSPERO registration number CRD42021209811.

Project description:The Kidney Failure Risk Equation (KFRE) predicts the need for dialysis or transplantation using age, sex, estimated glomerular filtration rate (eGFR), and urine albumin to creatinine ratio (ACR). The eGFR and ACR have known biological and analytical variability. We examined the effect of biological and analytical variability of eGFR and ACR on the 2-year KFRE predicted kidney failure probabilities using single measure and the average of repeat measures of simulated eGFR and ACR. Previously reported values for coefficient of variation (CV) for ACR and eGFR were used to calculate day to day variability. Variation was also examined with outpatient laboratory data from patients with an eGFR between 15 and 50 mL/min/1.72 m2. A web application was developed to calculate and model day to day variation in risk. The biological and analytical variability related to ACR and eGFR lead to variation in the predicted probability of kidney failure. A male patient age 50, ACR 30 mg/mmol and eGFR 25, had a day to day variation in risk of 7% (KFRE point estimate: 17%, variability range 14% to 21%). The addition of inter laboratory variation due to different instrumentation increased the variability to 9% (KFRE point estimate 17%, variability range 13% to 22%). Averaging of repeated measures of eGFR and ACR significantly decreased the variability (KFRE point estimate 17%, variability range 15% to 19%). These findings were consistent when using outpatient laboratory data which showed that most patients had a KFRE 2-year risk variability of ≤ 5% (79% of patients). Approximately 13% of patients had variability from 5-10% and 8% had variability > 10%. The mean age (SD) of this cohort was 64 (15) years, 36% were females, the mean (SD) eGFR was 32 (10) ml/min/1.73m2 and median (IQR) ACR was 22.7 (110). Biological and analytical variation intrinsic to the eGFR and ACR may lead to a substantial degree of variability that decreases with repeat measures. Use of a web application may help physicians and patients understand individual patient's risk variability and communicate risk (https://mccudden.shinyapps.io/kfre_app/). The web application allows the user to alter age, gender, eGFR, ACR, CV (for both eGFR and ACR) as well as units of measurements for ACR (g/mol versus mg/g).

Project description:Background The COVID-19 pandemic forced Veterans Health Administration facilities to rapidly adopt and deploy telehealth alternatives to provide continuity of care to veterans while minimizing physical contact. The impact of moving to virtual visits on patients with congestive heart failure (HF) is unknown. The goal of this study was to understand how patients with HF and their providers experienced the shift to telehealth for managing a chronic condition, and to inform best practices for continued telehealth use. Methods and Results We identified Veterans Health Administration Medical Centers with high telehealth use before COVID-19 and sites that were forced to adopt telehealth in response to COVID-19, and interviewed cardiology providers and veterans with HF about their experiences using telehealth. Interviews were recorded, transcribed, and analyzed using team-based rapid content analysis. We identified 3 trajectory patterns for cardiology telehealth use before and during COVID-19. They were the low-use class (low to low), high-use class (relatively high to higher), and increased-use class (low to high). The high-use and increased-use classes fit the criteria for sites that had high telehealth use before COVID-19 and sites that rapidly adopted telehealth in response to COVID-19. There were 12 sites in the high-use class and 4 sites in the increased-use class. To match with the number of sites in the increased-use class, we selected the top 4 sites by looking at the months before COVID-19. We identified 3 themes related to telehealth use among patients with HF and cardiology providers: (1) technology was the primary barrier for both patients and providers; (2) infrastructural support was the primary facilitator for providers; and (3) both patients and providers had largely neutral opinions on how telehealth compares to in-person care but described situations in which telehealth is not appropriate. Conclusions Only 12 sites fit the criteria of high telehealth use in cardiology before COVID-19, and 4 fit the criteria of low use that increased in response to COVID-19. Patients and providers at both site types were largely satisfied using telehealth to manage HF. Understanding best practices for managing ambulatory care-sensitive conditions through virtual visits can help the Veterans Health Administration prepare for long-term impacts of COVID-19 on in-person visits, as well as improve access to care for veterans who live remotely or who have difficulty traveling to in-person appointments.

Project description:Rationale & objectiveThe 4-variable kidney failure risk equation (KFRE) allows for the prediction of chronic kidney disease (CKD) progression using age, sex, estimated glomerular filtration rate, and urine albumin/creatinine ratio. Electronic health records enable KFRE auto-calculation, and registries allow population-level application. We assessed whether 2-year KFRE score categories are associated with CKD care metrics.Study designCross-sectional cohort.Setting & participantsThis study included individuals with CKD in March 2020 who were receiving care within the Partners HealthCare system in Massachusetts.OutcomesThe presence of sufficient data to calculate the KFRE and, among those with a KFRE score, performance on CKD clinical care metrics, including (1) prescription of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker; (2) blood pressure at goal (<140/90 mm Hg) based on clinic measurements; (3) composite metric of hepatitis B virus immunity; (4) composite metric of referral, evaluation, or waitlist status for kidney transplantation; (5) advance directive documentation; (6) yearly influenza vaccination; and (7) pneumonia vaccination.Analytical approachMultivariable logistic regression analysis was used to analyze the association of KFRE score category with CKD care metrics.ResultsOf 61,546 patients, 18,272 (30%) had auto-calculated 2-year KFRE scores; the remaining patients lacked KFRE scores because of absent albuminuria assessment. Individuals with a KFRE score were more likely to have a primary care provider or nephrologist. Among patients with 2-year KFRE scores, high-risk patients had increased odds of completing advance directives (OR, 1.52; 95% CI, 1.07-2.17), while low-risk patients had decreased odds of influenza vaccination (OR, 0.85; 95% CI, 0.75-0.97). Patients with moderate- and high-risk KFRE scores had lower odds of having blood pressure at goal (OR, 0.77; 95% CI, 0.61-0.96 and OR, 0.63; 95% CI, 0.44-0.88, respectively).LimitationsAlbuminuria data may have been assessed outside of the Partners system.ConclusionsA higher-risk KFRE score is associated with the delivery of some but not all CKD care measures. An opportunity exists to improve albuminuria measurement.
