Chronic kidney disease (CKD) is an escalating global health problem that disproportionately affects rural populations, especially in low- and middle-income countries (LMICs). The review emphasizes that limited access to specialist care, diagnostic services, and renal replacement therapies contributes to worse outcomes for people living in remote areas. Importantly, CKD is projected to become the fifth leading cause of death by 2040, underscoring the urgency of developing alternatives to traditional facility-based care to meet Sustainable Development Goal 3 (SDG 3) targets for health and well-being.
Multiple interrelated barriers restrict access to quality nephrology care in rural regions. Geographic distance to specialist centres and long travel times increase direct and indirect costs for patients and families. There is a noted shortage of nephrology specialists in rural and resource-limited health systems, and local healthcare infrastructure—laboratory, imaging, and dialysis capacity—may be insufficient. These system-level constraints, compounded by socioeconomic factors, create substantial inequities in diagnosis, monitoring, and treatment of CKD.
The COVID-19 pandemic accelerated the use of telemedicine broadly and provided practical lessons relevant to nephrology. The review reports that telenephrology was successfully deployed for aspects of kidney care during the pandemic, demonstrating feasibility for remote consultations, follow-up, and some monitoring tasks. Despite this success, uptake among underserved populations has been uneven. Barriers to adoption include limited digital connectivity, lack of devices or digital literacy among patients, and health system readiness to integrate remote care workflows.
Empirical reports from remote and resource-constrained settings indicate several favorable outcomes associated with telenephrology use. Across studied populations, telenephrology was associated with shorter waiting times for specialist input, lower overall costs to patients and health systems, reduced need for health-related travel, and higher overall patient satisfaction. The review also notes reports of lower mortality rates in some implementations, suggesting potential clinical benefit when telenephrology is appropriately integrated into care pathways. These findings are presented as evidence that the challenges to delivering remote nephrology care in underserved areas can be overcome in real-world programs.
The review highlights key enablers needed to scale telenephrology in rural settings. Governmental support and policy frameworks are identified as fundamental to legitimizing and financing telehealth services. Investment in digital infrastructure—reliable broadband, connectivity, and compatible hardware—is required to reach remote communities. Addressing the digital divide is critical; this includes ensuring access to devices, affordable internet, and digital literacy training for patients and local providers. Community engagement is emphasized as necessary to build trust, tailor services to local needs, and ensure cultural and contextual appropriateness. The authors stress that these elements, taken together, determine whether telenephrology can sustainably reduce kidney health inequities.
Telenephrology is framed in the review as a technological strategy to address kidney health inequities and to advance global health goals. For telenephrology to contribute meaningfully to reductions in CKD morbidity and mortality, coordinated action is required across policy makers, health systems, and communities. Policy measures must support workforce distribution, financing mechanisms, regulatory clarity for telehealth practice, and data governance. The review calls for targeted investments and strategies that align telenephrology deployment with national health priorities and the broader agenda of SDG 3.
Overall, the review positions telenephrology as a feasible and promising approach to improve access to nephrology care for rural patients. Reported program-level benefits include faster access to care, cost reductions, decreased travel burden, improved patient satisfaction, and in some reports, lower mortality. However, the review emphasizes that evidence of success depends on contextual enablers: government support, digital infrastructure, bridging the digital divide, and active community engagement. The article is a review and synthesizes available evidence; specific program details, effect sizes, and study-level methodology are not presented in depth in the abstract. For granular data and implementation case studies, readers are referred to the full text and referenced literature.
References cited in the review include international guidance on telehealth implementation and studies on telenephrology, global CKD burden estimates, and reports on access to dialysis and acute kidney injury in low-resource settings. The review therefore situates telenephrology within an evidence base spanning policy toolkits, observational reports, and prior syntheses of telemedicine in nephrology.
