Acute Kidney Injury
Conditions
Brief summary
The aim of our study is to analyze the accurate diagnosis and prognosis of acute kidney injury (AKI) based on its severity and to define long-term clinical and socioeconomic outcomes. Investigators defined the AKI group among adults aged 20 years or older who visited enrolled center and underwent at least two blood tests, including serum creatinine, within an interval of 7 days or less and a control group was matched 1:1 to the AKI group based on age, sex, year of visit, and baseline kidney function, forming the study population. Investigators then collected and analyzed various clinical, laboratory, and hospitalization records including demographic data, anthropometric data, laboratory data, and medical history.
