초록	Background: Acute kidney injury (AKI) is defined and staged according to serum creatinine levels. The prognosis is associated with the degree of creatinine increment. However, the long-term prognosis of rapidly reversed AKI irrespective of severity has not been well evaluated in hospital and intensive care unit setting (ICU). Material and Methods: We analyzed two cohorts of hospital-acquired AKI in teaching hospital. The definition and severity AKI was classified according to the AKI Network (AKIN) staging criteria. First cohort was prospective enrolled hospital acquired AKIs from from September 2007 to August 2008 and followed up their long-term outcomes until 2011. In second cohort, we enrolled critically ill patients AKI in ICU from 2008 for 1 year and follow up until 2011. The duration of AKI was categorized as AKI for 1 to 2 (rapidly reversed AKI), 3 to 6 (medium duration AKI), at least 7 days (long-duaration AKI) and persistent AKI, depending on renal recovery to baseline at the time of discharge. Results: The data showed that persistent AKI and AKIN stage 3 were both associated with high mortality rates in both cohorts. The long term outcome of rapid reveral AKI was similar to that of long duration of AKI (Fig. 1). The data showed that persistent AKI and AKIN stage 3 were both associated with high mortality rates, but, there were no differences between the long-term outcomes of each duration group Conclusions: The severity and reversibility of AKI influence the hospitalized patients’ mortality rates. Rapidly reversed AKI has the same effects over the long-term outcome compared to the long late reversal group in hospital setting and in ICU setting.
