Zusammenfassung: | Background
Regular clinic follow‐up is a prerequisite for optimal antiviral therapy and surveillance of hepatocellular carcinoma in patients with chronic hepatitis B (CHB). However, adherence to regular follow‐up stays low in practice. This study investigated whether regular follow‐up is associated with decreased liver cancer mortality in CHB patients.
Methods
A nationwide population‐based historical cohort study was conducted using customized data from the National Health Insurance Service of Korea. The number of hospital visits every 3‐month interval was counted for 2 years from the date of CHB diagnosis. Patients were classified into three follow‐up groups: regular (four to eight visits), irregular (one to three visits), and no follow‐up. The risk of liver cancer mortality was compared among the groups using Cox proportional hazard regression analysis.
Results
Of the 414 074 CHB patients, 22.9% had regular follow‐up. In multivariable analysis, regular follow‐up was independently associated with decreased risk of liver cancer mortality compared to no follow‐up (hazard ratio [HR], 0.56; 95% confidence interval [CI], 0.50‐0.63, P |
