Acute kidney injury (AKI) is common across the world. AKI that is acquired in the community (community acquired AKI, CA-AKI) has different risk factors, epidemiological profile, presentation and impact as compared to hospital acquired AKI (HA-AKI). Hence, similar approaches to tackle CA-AKI and HA-AKI might not work. This review highlights the important differences between the two entities that have a bearing on the overall approach to the conditions and how CA-AKI has been overshadowed by HA-AKI in research, diagnosis and treatment recommendations and clinical practice guidelines.
The overall burden of AKI is disproportionately more in low and low-middle income countries. The Global Snapshot study of International Society of Nephrology’s (ISN) AKI 0by25 program has shown that CA-AKI is the dominant form in these settings. Its profile and outcomes vary with geographical and socio-economic characteristics of the regions where it develops. The current clinical practice guidelines for AKI align more with HA-AKI than CA-AKI, and fail to capture the complete spectrum of CA-AKI as well as its impact. The ISN AKI 0by25 studies have uncovered the circumstantial compulsions in defining and assessing AKI in these settings and shown feasibility of community-based interventions.
Efforts are needed to better understand CA-AKI in low-resource settings and develop context specific guidance and interventions. A multidisciplinary, collaborative approach with representation from community would be required.
