    The incidence of acute kidney injury (AKI) among acutely ill patients is reportedly very high and has vexing consequences on patient outcomes and health care systems. The risks and impact of AKI differ between developed and developing countries. Among developing countries, AKI occurs in young individuals with no or limited comorbidities, and is usually due to environmental causes, including infectious diseases. Although several risk factors have been identified for AKI in different settings, there is limited information on how risk assessment can be used at population and patient levels to improve care in patients with AKI, particularly in developing countries where significant health disparities may exist. The Acute Disease Quality Initiative consensus conference work group addressed the issue of identifying risk factors for AKI and provided recommendations for developing individualized risk stratification strategies to improve care. We proposed a 5-dimension, evidence-based categorization of AKI risk that allows clinicians and investigators to study, define, and implement individualized risk assessment tools for the region or country where they practice. These dimensions include environmental, socioeconomic and cultural factors, processes of care, exposures, and the inherent risks of AKI. We provide examples of these risks and describe approaches for risk assessments in the developing world. We anticipate that these recommendations will be useful for health care providers to plan and execute interventions to limit the impact of AKI on society and each individual patient. Using a modified Delphi process, this group reached consensus regarding several aspects of AKI risk stratification.

    BACKGROUND: Acute kidney injury (AKI) is associated with significant short-term morbidity and mortality. However, its long-term outcomes, particularly in resource-limited settings, remain poorly understood. This study aimed to evaluate 2-year major adverse kidney events (MAKE) in patients with severe AKI.

    METHODS: We analyzed data from the India and Southeast Asia Renal Replacement Therapy (InSEA-RRT) registry, a multicenter cohort study conducted between April 2019 and December 2023 across 24 hospitals in Southeast Asia and India. Critically ill patients with AKI stage 3, as defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria, were enrolled. The primary outcome was 2-year MAKE, defined as a composite of persistent kidney dysfunction, long-term dialysis, and all-cause mortality at 2 years post-enrollment.

    RESULTS: A total of 2,315 patients were enrolled, of whom 1,033 (47%) died during hospitalization. Among surviving patients, the incidence of 2-year MAKE was 46.6 per 100 person-years (95% CI 42.7-50.6). Notably, mortality (32%) was the dominant component of MAKE. The incidence of new chronic kidney disease (CKD) and CKD progression at 2 years post-AKI was 58.6 and 35.4 per 100 person-year (95% CI 51.0-67.0 and 26.0-47.0), respectively. Multivariable-adjusted models identified older age, male sex, preexisting CKD, malignancy, cardiac-associated AKI, and non-recovery of kidney function after AKI as independent risk factors for 2-year MAKE.

    CONCLUSIONS: Patients with severe AKI face a high incidence of 2-year MAKE and poor long-term clinical outcomes. Early recognition and close follow-up of these patients are crucial. Further research is needed to identify effective strategies to improve long-term outcomes in this high-risk population.
