Background
Chronic kidney disease (CKD) is a significant public health burden worldwide. Previous studies demonstrate that diabetes exceeded glomerulonephritis and became the leading cause of CKD in China, but the transition of other causes was still unclear.
Methods
We utilized a national in-patients database covering 878 class 3 hospitals (which provide primary, secondary and tertiary care to nationwide patients) and involving 64.7 million adult patients from 2010 to 2015. The specific causes of CKD were extracted from International Classification of Diseases-10 codes of discharge diagnoses.
Results
Altogether 4.5% of hospitalized patients (1.8 million) were identified as having CKD, with an increased percentage from 2010 (3.7%) to 2015 (4.7%). Increasing trends of diabetic kidney disease and hypertensive kidney damage were observed from 2010 to 2015, especially for northern urban areas. The percentage of obstructive nephropathy also increased gradually and constituted an important cause of CKD for southern rural residents.
Conclusion
The spectrum of etiologies of CKD is changing in China, and varies over time and geographic regions.
