Survivors of acute kidney injury (AKI) are at increased risk of major adverse kidney events and international guidelines recommend individuals be evaluated 3 months following AKI. We describe practice patterns and predictors of post-AKI care in an Australian tertiary hospital. A retrospective analysis was undertaken of adults with AKI (defined by KDIGO criteria) admitted to a single centre between 2012 and 2016. The primary outcome was outpatient nephrology review at 3 months. Secondary outcomes included inpatient nephrology review, and outpatient serum creatinine and urinary protein measurements. Data were analysed using multivariable logistic and competing risk regression. Only 117 of 2111 patients with AKI (6%) were reviewed by a nephrologist at 3 months. Reviewed patients were more likely to have a higher discharge serum creatinine (OR 1.20 per 10 μmol/L increase, 95% CI 1.16-1.25) or a history of peripheral vascular disease (OR 1.77, 95% CI 1.00-3.14). They were less likely to be older (OR 0.66 per decade, 95% CI 0.57-0.76), or to have a history of liver (OR 0.47, 95% CI 0.26-0.87) or ischaemic heart disease (OR 0.50, 95% CI 0.27-0.94). AKI stage did not predict follow up. The median time from discharge to outpatient serum creatinine testing was 12 days (IQR 4-47) and proteinuria was measured in 538 patients (25%). A minority of admitted AKI patients receive recommended post-AKI care. Studies in other Australian institutions are required to confirm or refute these concerning findings.
