China Collaborative Study on Epidemiology of Acute Kidney Injury

China Collaborative Study on Epidemiology of Acute Kidney Injury

Acute kidney injury (AKI) is a common clinical syndrome, especially patients in the hospital. AKI has become a huge medical burden in China. Little information is available about this disease burden in our country. The investigators aimed to evaluate the burden of AKI and to analyze the related risk factors.

The investigators launch a nationwide of all patients, who were admitted to hospital from 2011-2016. Patients were diagnosed on the basis of changes in serum creatinine by the laboratory information system. The investigators assessed rates of AKI according to the criteria of 2012 Kidney Disease Improving Global Outcomes (KDIGO).

Inclusion Criteria:

• The patients diagnosed on the basis of changes in serum creatinine according to the criteria of 2012 Kidney Disease Improving Global Outcomes(KDIGO)

Exclusion Criteria:

• Serum creatinine record less than two times during hospitalization
• Patients being diagnosed with End-stage kidney disease (chronic kidney disease stage 5)
• Nephrectomy
• Kidney transplantation
• Peak serum creatinine of less than 53µ mol/L
• Serum creatinine decrease after amputation
