Kidney care in low- and middle-income countries.

Abstract

Optimal kidney care requires a trained nephrology workforce, essential healthcare services, and medications. This study aimed to identify the access to these resources on a global scale using data from the multinational survey conducted by the International Society of Nephrology (ISN) (Global Kidney Health Atlas (GKHA) project), with emphasis on developing nations. For data analysis, the 125 participating countries were sorted into the 4 World Bank income groups: low income (LIC), lower-middle income (LMIC), upper-middle income (UMIC), and high income (HIC). A severe shortage of nephrologists was observed in LIC and LMIC with < 5 nephrologists per million population. Many LIC were unable to access estimated glomerular filtration rate (eGFR) and albuminuria (proteinuria) tests in primary-care levels. Acute and chronic hemodialysis was available in most countries, although acute and chronic peritoneal dialysis access was severely limited in LIC (24% and 35%, respectively). Most countries had kidney transplantation access, except for LIC (12%). HIC and UMIC funded their renal replacement therapy (RRT) and renal medications primarily through public means, whereas LMIC and LIC required private and out-of-pocket contributions. In conclusion, this study found a huge gap in the availability and access to trained nephrology workforce, tools for diagnosis and management of CKD, RRT, and funding of RRT and essential medications in LIC and LMIC.
