Trends of treated hepatitis B, hepatitis C, and tuberculosis infection in long-term hemodialysis patients in Taiwan: A nationwide survey in 2010–2018

Abstract

Background/Purpose: Hepatitis B virus (HBV), hepatitis C virus (HCV), and tuberculosis (TB) infections affect patient morbidity and mortality and challenge infection control procedures within dialysis facilities. Thus, updated information on the yearly infection trends in the dialysis population is pivotal to preventing and improving the management of these infectious diseases. Methods: This study used reimbursement data from the Taiwan National Health Insurance Research Database. Long-term hemodialysis (HD) patients were defined as those receiving regular HD for more than 3 months. Treated HBV, HCV, and TB cases were defined according to the diagnosis codes, together with specified prescriptions. Liver malignancy and liver-related mortality were determined by the disease diagnosis. Results: The long-term HD population in Taiwan grew from 57,539 in 2010 to 74,203 in 2018. The mean number of treated HBV, HCV, and TB cases in the HD population was 254 (3.9 per thousand HD patients), 136 (2.0 per thousand), and 165 (2.6 per thousand), respectively. An increasing trend of treated viral hepatitis and a mildly decreasing trend in treated TB were observed. Liver outcome showed an increasing trend in liver malignancy prevalence and a stationary trend of liver-related mortality. Treated HBV and TB, liver malignancy, and liver-associated mortality were higher in men than women (all p < 0.001). The burden of liver complications was higher in southern Taiwan. Conclusion: The increasing yearly trend of treated HBV and HCV and a stable trend of treated TB provide evidence for further infection control management and risk population identification of the HD population.
