N2 - Aim: While patients with chronic kidney disease have reduced health‐related quality of life (HRQOL), long‐term HRQOL of survivors of severe acute kidney injury (AKI) remains unclear. Methods: We analysed HRQOL from the Prolonged Outcomes Study of the Randomized Evaluation of Normal versus Augmented Level Replacement Therapy (POST‐RENAL) study and compared findings with those from a general Australian adult population enrolled in the Australian Diabetes, Obesity and Lifestyle (AusDiab) study. We used a multivariate analysis adjusted for baseline characteristics along with sensitivity analysis using age and sex‐matched case controls. Results: In the POST‐RENAL study, 282 participants had HRQOL data collected using the SF‐12 questionnaire. This was compared with 6330 participants from the AusDiab study. Unadjusted analyses showed that POST‐RENAL participants had lower physical component scores (PCS, mean score 40.0 vs 49.8, P < 0.0001) and lower mental component scores (MCS, mean score 49.8 vs 53.9, P < 0.0001) than the AusDiab group. After age and sex matching, the difference in PCS and MCS remained statistically significant (P < 0.0001). Advanced age, reduced renal function and albuminuria (all P ≤ 0.01) were all strongly associated with lower PCS values but not MCS values. After matching subsets of the cohorts on the basis of age, sex and renal function, PCS and MCS were lower in the POST‐RENAL group (P < 0.0001). Conclusion: Survivors of severe AKI in the POST‐RENAL study had lower physical and mental components of HRQOL compared with general population, even after adjustment for their reduced renal function. Increasing age and reduced renal function were associated with poorer physical QOL.
