Global structures, practices, and tools for provision of hemodialysis.

BACKGROUND

Hemodialysis (HD) is the most commonly utilized modality for kidney replacement therapy worldwide. This study assesses the organizational structures, availability, accessibility, affordability and quality of HD care worldwide.

METHODS

This cross-sectional study relied on desk research data as well as survey data from stakeholders (clinicians, policymakers and patient advocates) from countries affiliated with the International Society of Nephrology from July to September 2022.

RESULTS

Overall, 167 countries or jurisdictions participated in the survey. In-center HD was available in 98% of countries with a median global prevalence of 322.7 [interquartile range (IQR) 76.3-648.8] per million population (pmp), ranging from 12.2 (IQR 3.9-103.0) pmp in Africa to 1575 (IQR 282.2-2106.8) pmp in North and East Asia. Overall, home HD was available in 30% of countries, mostly in countries of Western Europe (82%). In 74% of countries, more than half of people with kidney failure were able to access HD. HD centers increased with increasing country income levels from 0.31 pmp in low-income countries to 9.31 pmp in high-income countries. Overall, the annual cost of in-center HD was US$19 380.3 (IQR 11 817.6-38 005.4), and was highest in North America and the Caribbean (US$39 825.9) and lowest in South Asia (US$4310.2). In 19% of countries, HD services could not be accessed by children.

CONCLUSIONS

This study shows significant variations that have remained consistent over the years in availability, access and affordability of HD across countries with severe limitations in lower-resourced countries.
