Health Care Resource Utilization and Related Costs of Patients With CKD From the United States: A Report From the DISCOVER CKD Retrospective Cohort.

ABSTRACT:

Introduction

It is well established that chronic kidney disease (CKD) results in a significant burden on patients' health and health care providers. However, detailed estimates of the health care resource utilization (HCRU) of CKD are limited, particularly those which consider severity, comorbidities, and payer type. This study aimed to bridge this evidence gap by reporting contemporary HCRU and costs in patients with CKD across the US health care providers.

Methods

Cost and HCRU estimates of CKD and reduced kidney function without CKD (estimated glomerular filtration rate [eGFR]: 60-75 and urine albumin-to-creatinine ratio [UACR]: <30) were derived for US patients included in the DISCOVER CKD cohort study, using linked inpatient and outpatient data from the limited claims-EMR data set (LCED) and TriNetX database. Patients with a history of transplant or undergoing dialysis were not included. HCRU and costs were stratified by CKD severity using UACR and eGFR.

Results

Overall health care costs ranged from $26,889 (A1) to $42,139 (A3), and from $28,627 (G2) to $42,902 (G5) per patient per year (PPPY), demonstrating a considerable early disease burden which continued to increase with declining kidney function. The PPPY costs of later stage CKD were particularly notable for patients with concomitant heart failure ($50,191 [A3]) and those covered by commercial payers ($55,735 [A3]).

Conclusions

Health care costs and resource use associated with CKD and reduced kidney function pose a substantial burden across health care systems and payers, increasing in line with CKD progression. Early CKD screening, particularly of UACR, paired with proactive disease management may provide both an improvement to patient outcomes and a significant HCRU and cost saving to health care providers.

Project description:IntroductionReal-world data reporting healthcare resource utilisation and costs associated with end-of-life care for patients with chronic kidney disease (CKD) are limited. We examined length of hospitalisation and costs associated with end-of-life inpatient encounters using retrospective data from DISCOVER CKD.MethodsData on inpatient encounters for patients with CKD aged ≥ 18 years between January 2016 and March 2020 were extracted from the US Premier Hospital Database. Encounters ending in death were identified and grouped by reason for the encounter, using the International Classification of Diseases, Tenth Revision, and by their insurance coverage. Encounters were evaluated overall and stratified according to cardiovascular (CV), kidney failure and infection-related reasons, and by their coverage by commercial, Medicaid, Medicare or other insurers. Length of hospitalisation and total costs were calculated for encounters.ResultsAmong 237,734 encounters ending in death, the mean [standard deviation (SD)] age was 74.2 (12.4) years, and 45.3% of patients were female. In total, 25,118, 4210 and 76,307 encounters were classified as relating to CV reasons, kidney failure and infection, respectively. Among all encounters, the mean (SD) length of hospitalisation ranged from 9.1 (11.2) (Medicare) to 12.8 (18.4) (Medicaid) days. Across insurers, encounters related to kidney failure were associated with the longest hospitalisations compared with CV and infection [mean range (days): 10.7-15.9 vs. 7.5-10.5 and 8.7-12.7, respectively]. The median [interquartile range (IQR)] total cost of any inpatient encounter was $17,057 ($8040-35,873). Kidney failure-related encounters had higher costs compared with CV and infection [median (IQR), $18,469 ($8673-38,315) vs. $17,503 ($7766-39,693) and $16,403 ($7762-34,910), respectively]. Medicaid-covered encounters had the highest costs of all insurers [median (IQR), $16,189 ($7725-33,443)].ConclusionsAmong patients with CKD, end-of-life encounters were most frequently related to infection. Encounters relating to kidney failure incurred the highest costs.Trial registrationClinicalTrials.gov identifier: NCT04034992.

Project description:IntroductionThis analysis examined the baseline characteristics and clinical outcomes of patients with chronic kidney disease (CKD) and rapid or non-rapid estimated glomerular filtration rate (eGFR) decline, using retrospective data from DISCOVER CKD (ClinicalTrials.gov, NCT04034992).MethodsData (2008-2020) were extracted from UK Clinical Practice Research Datalink, US TriNetX, US Limited Claims and Electronic Health Record Dataset, and Japan Medical Data Vision. Patients with CKD (two consecutive eGFR measures < 75 mL/min/1.73 m2 recorded 90-730 days apart) were included. Rapid eGFR decline was defined as an annual decline of > 4 mL/min/1.73 m2 at 2 years post-index; non-rapid eGFR decline was defined as an annual decline of ≤ 4 mL/min/1.73 m2. Clinical outcomes assessed included all-cause mortality, kidney outcomes (composite risk of kidney failure [progression to CKD stage 5] or > 50% eGFR decline, and kidney failure alone), cardiovascular events-including major adverse cardiovascular events (MACE; non-fatal myocardial infarction/stroke and cardiovascular death)-and all-cause hospitalization.ResultsAcross databases, rapid eGFR decline occurred in 13.7% of 804,237 eligible patients. Mean annual eGFR decline ranged between - 6.21 and - 6.86 mL/min/1.73 m2 in patients with rapid eGFR decline versus between - 0.11 and - 0.77 mL/min/1.73 m2 in patients with non-rapid eGFR decline. Rapid eGFR decline was associated with increased comorbidity burden and medication prescriptions. Across databases, the composite risk of kidney failure or > 50% decline in eGFR was significantly greater in patients with rapid versus non-rapid eGFR decline (P < 0.01); all-cause mortality, kidney failure alone, MACE, and all-cause hospitalization each significantly increased in two databases (P < 0.01-0.05).ConclusionUnderstanding patient factors associated with rapid eGFR decline in patients with CKD may help identify individuals who would benefit from proactive management to minimize the risk of adverse outcomes.Trial registrationClinicalTrials.gov identifier, NCT04034992.

Project description:Rationale & objectiveAmong patients with IgA nephropathy (IgAN), proteinuria and decline in kidney function may be associated with increased economic burden. This study aimed to provide current information on the epidemiology and economic burden of IgAN in the United States.Study designRetrospective cohort study.Setting & study populationOverall, 9,984 patients in the Optum's Market Clarity database identified by the presence of at least 2 natural language processing-derived IgAN signs and disease and symptoms terms; 813 with linked claims data included in a health care resource utilization/cost subcohort.PredictorHigh-risk proteinuria (≥1 g/d), chronic kidney disease (CKD) stage.OutcomesStandardized prevalence, health care resource utilization, costs.Analytical approachDescriptive statistics for categorical and continuous variables. Direct standardization for prevalence estimation. Generalized linear models for health care resource utilization/costs, reported as per-patient-per-month (PPPM) costs in 2020 US dollars.ResultsThe estimated standardized US prevalence of IgAN (2016-2020) was 329.0 per 1,000,000 persons. High-risk proteinuria (≥1 vs <1 g/d) was associated with a higher mean PPPM number of outpatient visits (3.49 vs 1.74; P = 0.01) and pharmacy claims (3.79 vs 2.41; P = 0.01), contributing to higher mean total costs PPPM ($3,732 vs $1,457; P = 0.01). Furthermore, higher CKD stage was also associated with higher health care resource utilization (number of outpatient visits PPPM, number of pharmacy claims PPPM, proportion of patients with inpatient visits and emergency department visits; P < 0.001) and mean total cost PPPM (from $2,111 CKD stage 1 to $10,703 CKD stage 5/kidney failure; P < 0.001).LimitationsGeneralizability outside of the catchment group for the database, missing data/errors inherent in retrospective database studies, relatively small sample size, use of Optum Market Clarity standardized pricing algorithms, exclusion of out-of-pocket costs.ConclusionsHealth care resource utilization and costs were higher for IgAN patients with high-risk proteinuria and worsening kidney function. Treatments that reduce proteinuria and slow CKD disease progression may reduce the economic burden associated with IgAN.Plain-language summaryImmunoglobulin A nephropathy (IgAN) is a rare kidney disease. Over time, the kidneys may leak protein into the urine (proteinuria). IgAN can lead to kidney failure. Because IgAN is rare, it is hard to know how many people have it. This study used electronic health records to estimate the number of patients with IgAN in the United States, describe the characteristics of patients, and understand their treatments and the costs. The number of patients with IgAN increased between 2016 and 2020. The researchers think this is because doctors learned more about IgAN. Patients with severe disease used more health care resources and had higher costs. The authors believe treatments that slow kidney damage may reduce the cost of treating IgAN.

Project description:Rationale & objectiveThe impact of chronic kidney disease (CKD) on inpatient health care use is unknown. This study aimed to describe the prevalence of pediatric CKD among children hospitalized in the United States and examine the association of CKD with hospital outcomes.Study designCross-sectional national survey of pediatric discharges.Setting & participantsHospital discharges of children (aged>28 days to 19 years) with a chronic medical diagnosis included in the Healthcare Cost and Utilization Project Kids' Inpatient Database for 2006, 2009, 2012, and 2016.PredictorPresence of primary or coexisting CKD as identified by diagnosis codes.OutcomesLength of stay (LOS), cost, and mortality.Analytical approachMultivariable analysis using Poisson, gamma, and logistic regressions were performed for LOS, cost, and mortality, respectively.ResultsA chronic medical condition was present in 6,524,745 estimated discharges during the study period and CKD was present among 3.9% of discharges (96.1% without CKD). Those with CKD had a longer LOS (median of 2.8 [IQR, 1.4-6.0] days compared with 1.8 [IQR, 1.0-4.4] days for those without a CKD diagnosis; P<0.001). Median cost was higher in the CKD group compared with the group without CKD, at $8,755 (IQR, $4,563-18,345) and $5,016 (IQR, $2,860-10,109) per hospitalization, respectively (P<0.001). Presence of CKD was associated with a longer LOS (29.9% [95% CI, 27.2%-32.6%] longer than those without CKD), higher cost (61.3% [95% CI, 57.4%-65.4%] greater than those without CKD), and higher risk for mortality (OR, 1.51 [95% CI, 1.40-1.63]).LimitationsLack of access to and adjustment for confounders including patient readmission and laboratory data.ConclusionsPediatric CKD was associated with longer LOS, higher costs, and higher risk for mortality compared with hospitalizations with other chronic illnesses. Further studies are needed to better understand the health care needs and delivery of care to hospitalized children with CKD.
