Diabetes-related kidney, eye, and foot disease in Taiwan: An analysis of nationwide data from 2005 to 2014

[[abstract]]BACKGROUND/PURPOSE: Patients with diabetes have a higher risk of developing chronic complications and cause a huge burden to the public health care system as well as on patients and their families. We studied these diabetic complications about kidney, eye and peripheral vascular diseases to understand their prevalence and distributions in a national survey. METHODS: We analyzed diabetic complications using National-Health-Insurance claims filed from 2005 to 2014. We used this database to evaluate their developments of kidney, eye, and peripheral vascular diseases according to the International-Classification-of-Diseases, Ninth Revision using clinical modification diagnosis codes. RESULTS: The prevalence of diabetic kidney disease (DKD) significantly increased from 10.49% to 17.92% from 2005 to 2014. The prevalence rate of diabetic foot significantly decreased from 1.34% to 1.05% from 2005 to 2014, and the rate of severe infection also significantly decreased from 50.69% to 45.85%. The amputation rate significantly decreased from 24.91% to 17.47% among all patients with diabetic foot. CONCLUSION: In this study, the trends in DKD and dialysis prevalence were similar to those of the 2012 report. The rate of increase in dialysis prevalence is lower in this study than in the 2012 report. The prevalence of diabetic foot, severe infection, and amputation in this report exhibited significantly decreasing trends. This improvement may be attributable to care from multidisciplinary teams. We should dedicate more resources to our prevention program of DKD and retinopathy to further improve outcomes in the future
