Community acquired acute kidney injury (AKI) may have a different long-term prognosis than hospital acquired AKI. Objectives: To compare long-term survival of patients with AKI with that of patients without AKI and with that of patients on chronic hemodialysis (HD). Methods: Patients with and without AKI diagnosed at admission were included, survival analysis using Kaplan-Meir with multivariate Cox proportional methods were used. A comparator group of patients on HD was also included in the analysis. The study covered the period between December 2011 and 31 December 2015. Results: A total of 47 patients with AKI, 93 without AKI and 138 in HD were included. There was no statistical difference in case fatality rates between patients with and without AKI at 3 (p=0.148) and 35 months (p=0.068). There was difference in case fatality rate between patients with AKI and HD (p=0.0002), but this difference disappeared after adjusting for age, serum albumin and lack of cancer (p=0.177). Variables that affected mortality in the multivariate analysis were advanced age (p=0.001), severe hypoalbuminemia (p=0.001) and concomitant cancer (p=0.03). Conclusions: Community acquired AKI has no effect on long-term survival of patients, which depends on age, malnutrition and concomitant cancer.
