Inclusivity in global research.

<div><p>Vulnerable populations, such as the elderly, children, displaced people, and refugees, often encounter challenges in accessing healthcare. In this study, we used data from the third iteration of the International Society of Nephrology Global Kidney Health Atlas (ISN-GKHA) to describe kidney care access and delivery to vulnerable populations across countries and regions. Using data from an international survey of clinicians, policymakers, and patient advocates, we assessed the funding and coverage of vulnerable populations on all aspects of kidney replacement therapies (KRT). Overall, 167 countries or jurisdictions participated in the survey, representing 97.4% of the world’s population. Children had less access than adults to KRT: hemodialysis (HD) in 74% of countries, peritoneal dialysis (PD) in 53% of countries, and kidney transplantation (KT) in 80% of countries. Available nephrologist workforce for pediatric kidney care was much lower than for adults (0.69 per million population [pmp] vs 10.08 pmp). Refugees or displaced people with kidney failure did not have access to HD, PD, or KT in 21%, 33%, and 37% of the participating countries, respectively. Low-income countries (LICs) were less likely to provide KRT access to refugees compared to high-income countries (HICs): HD: 13% vs 22%; PD: 19% vs 61%; KT: 30% vs 44%. Testing for kidney disease was routinely offered to elderly people in only 61% of countries: LICs (45%), lower-middle-income countries (56%), upper-middle-income countries (54%), and HICs (75%). Equitable access to kidney care for vulnerable people, particularly for children and displaced people, remains an area of unmet need. Strategies are needed to address this issue.</p></div>
