The current nomenclature for cardiorenal syndrome is problematic owing to its chronological approach and the systemic nature of some of the subtypes. We suggest adoption of a new concept, chronic cardiovascular–kidney disorder, that better reflects the contributions of common risk factors and shared pathophysiological mechanisms.

First Nations peoples in Australia face systemic inequities in access to kidney transplantation. The National Indigenous Kidney Transplant Taskforce was established to address these. It has provided support to clinicians to implement and evaluate innovative practices and developed strategies to address biases in the structures and models of care that create barriers to wait-listing.

Digital transformation offers unprecedented opportunities for advancing healthcare, but also raises complex ethical and legal challenges. Emerging drivers of health disparity termed ‘digital determinants of health’ call for purposeful, equity-focused strategies to ensure that technological innovation benefits all without exacerbating disparities.

Among global destabilizing events, natural disasters often receive widespread attention whereas protracted conflicts and economic crises fade into the background. Low- and middle-income countries bear the brunt of this indifference, resulting in severely weakened health systems. People who require dialysis are particularly vulnerable, necessitating urgent collaboration to ensure equitable and sustainable care during such crises.

A lack of federal access to health-care resources for undocumented immigrants in the USA has led to variability in access to health care — including dialysis — across states. Transforming dialysis care for these individuals is justified both on humanitarian and economic grounds, but requires a roadmap for advocacy and stakeholder engagement.

Individuals who are members of multiple marginalized populations experience multiple axes of oppression and discrimination. Such intersectional discrimination can have interactive, negative effects on all aspects of life, including health. To achieve health equity, intersectional-discrimination-induced kidney harms must be examined, measured and mitigated.

Chronic kidney disease (CKD) is highly prevalent in women in perimenopause and menopause. Both CKD and menopause affect several important pathologies, such as cardiovascular disease (CVD) and bone mineral disease. More research is needed to better understand the relationships between menopause, CKD, CVD and bone disease.

The importance of incorporating factors related to sex and gender in all aspects of research is increasingly recognized. Kidney disease pathophysiology, presentation, response to therapy and outcomes differ by sex and gender, but these factors are often not considered in basic and clinical studies. It is time for nephrology to catch up.

Specific policies embedded in organ and tissue donation and transplantation systems discriminate against sexual orientation- and gender identity-diverse populations, restricting or excluding the use of donated organs and tissues. Revision of these policies is needed to promote equity and increase the supply of high-quality organs and tissues for those who need them.

The advancement of women to leadership positions in nephrology lags behind that of men by several metrics. Proactive, intentional approaches, including mentorship and sponsorship, family-friendly policies, career development in hard and soft skills, combatting bias and use of transparent institutional metrics of women’s advancement, are required to address this disparity.

Understanding of the barriers to adequate health care experienced by sexual and gender minority (SGM) people cannot be achieved in the absence of robust and appropriate data. The inclusion of SGM populations in health research and the collection of sexual orientation and gender identity data in research and routine clinical practice is therefore essential to understanding the unique needs of these populations and addressing inequities in health outcomes.

Blockchains enable secure data storage, the verification of data origin and accurate registration of changes in information over time. The widespread adoption of blockchain in nephrology could affect clinical practice and research by enhancing the quality of electronic health records and datasets.

Optimal referral of patients who are at risk of kidney failure to nephrologists could improve their long-term outcomes. Various strategies, including the inclusion of kidney failure risk equations in electronic medical records and the active dissemination of clinical practice guidelines, could help to reduce the gap between optimal referral and what currently happens in clinical practice.

Access to essential medical care can be compromised by social disruptions (such as riots and labour strikes), armed conflict and natural disasters, including extreme weather events. A successful response to such events requires forward planning, preparation and rehearsal with involvement of health-care systems, professionals, patients and their support networks. Following execution of the response, after-action evaluation is required to improve future responses.

People with kidney disease are particularly vulnerable to the impacts of natural disasters and extreme weather events. As climate change is increasing the frequency and severity of these events, a robust response is needed to improve disaster preparedness and increase the resilience of these patients.

Thousands of environmental chemicals are used globally. However, despite clear evidence of their adverse effects on the kidney, substantial knowledge gaps remain. Further studies are needed to better understand the effects of chemical mixtures, windows of physiological susceptibility, vulnerable populations, and the intersection of chemical exposure with health risks associated with climate change and heat stress.

Climate change is increasing global temperatures and causing more frequent and severe extreme heat events. The resulting additional disease burden is inequitably distributed. Strategies that reduce inequities in heat exposure and vulnerability to heat-related illness, as well as health protections at multiple levels (from individual to regional), are urgently needed to contain the looming crisis.

Adequate nutrition is essential for kidney health; however, attempts to improve nutrition and food security have been hindered in recent years by man-made and natural disasters. Approaches to eradicate famine, improve nutritional status and reduce food insecurity are needed to reduce inequities and maintain kidney health in the face of adverse circumstances.

The COVID-19 pandemic exposed flaws in the ability of the nephrology community to efficiently inform clinical decision making. To improve preparedness for the next pandemic, the nephrology community must work more closely together to ensure that research efforts are aligned and put in place a strategy for the effective dissemination of high-quality evidence in real-time.
