Global, regional, and national prevalence of kidney failure with replacement therapy and associated aetiologies, 1990–2023: a systematic analysis for the Global Burden of Disease Study 2023
Bibliographic record
Abstract
BACKGROUND: Kidney failure with replacement therapy (KFRT) such as dialysis or transplantation represents a severe stage of chronic kidney disease (CKD) and poses a major global health burden. Although many CKD cases are diagnosed in the earlier stages, the greatest risk occurs when CKD progresses to KFRT. Despite its considerable financial and imposing impact on public health, there is a notable gap in international policies addressing CKD and KFRT. To bridge this gap and help policy makers and health systems effectively tackle the public health challenge of KFRT, a better understanding of the disease burden is essential. Thus, this analysis aims to provide a detailed overview of the global prevalence of KFRT and its associated aetiologies with estimates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) from 1990 to 2023. METHODS: This study defined KFRT as individuals on maintenance dialysis for 90 days or more or those who have undergone a kidney transplant, aligning with the Kidney Disease: Improving Global Outcomes (KDIGO) 2024 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease. Renal registries served as the primary data sources. Prevalence and underlying aetiology estimates (type 1 diabetes, type 2 diabetes, hypertension, glomerulonephritis, and other causes) were generated with DisMod-MR 2.1, an epidemiological Bayesian mixed-effects meta-regression modelling tool. Both all-age and age-standardised estimates were reported and accompanied with 95% uncertainty intervals (UIs). FINDINGS: In 2023, the number of global cases of KFRT was 4·59 million (95% UI 4·17-5·08) for both sexes and all ages, with an age-standardised prevalence of 50·7 (46·1-56·0) per 100 000 population. Over the past three decades, there has been a steady increase in KFRT prevalence globally. The highest prevalence was found in the GBD high-income regions, while the lowest was observed in sub-Saharan Africa. KFRT prevalence was generally higher in countries classified within the World Bank's high-income and upper-middle-income groups, while lower prevalence was more common in countries within the World Bank's low-income and lower-middle-income groups. Additionally, a pronounced sex disparity was identified, where male dialysis and transplant prevalence estimates were consistently higher than those for females in most countries. Type 2 diabetes and hypertension were among the leading associated aetiologies of KFRT globally. From 1990 to 2023, the all-age and age-standardised prevalence estimates across the ascribed aetiologies increased for KFRT, with the largest increases associated with type 2 diabetes and hypertension. INTERPRETATION: KFRT affects approximately 5 million people globally, with high treatment and mortality costs. Our study unveiled considerable geographical variation in KFRT prevalence, which should be seen as indicators of health-care system opportunities. As the prevalence of the leading aetiologies of KFRT-type 2 diabetes and hypertension-continues to rise, there is a crucial need to prioritise the development and implementation of cost-effective strategies aimed at preventing CKD and its progression to KFRT, particularly in low-resource settings. These preventive efforts must happen in tandem with efforts to expand capacity for dialysis and transplant services. FUNDING: Gates Foundation.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
