Successful hepatitis B and C screening in the health check-up in the German primary care setting

A goal of the World Health Organization's global hepatitis strategy is the elimination of chronic hepatitis C virus (HCV) infection by 2030. As part of its strategy, the Federal Joint Committee (Germany) decided to include hepatitis B and C screening in a preventive medical examination, which is performed at the primary care level in Germany. We investigated the results 1 year after implementation of screening between October 2021 and September 2022.

HBsAg/HBV DNA and anti-HCV/HCV RNA screenings were identified by billing categories in 286,192 individuals of 11 ambulatory healthcare centers.

Compared to 30,106 HBsAg and 31,266 anti-HCV laboratory requisitions in the year 2018, the number of tests increased to 286,192 during the screening period. Compared to routine care, additional anti-HCV positive tests age dependently increased the tally by 98% (177 plus 170 positive cases in males) and 123% (96 plus 118 positive cases in females) in those aged 35-44 years up to 518% (17 plus 88 positive cases in males) and 514% (29 plus 149 positive cases in females) in those aged 75-84 years. Similar results were observed for HBsAg. Prevalences of HBsAg, anti-HCV and HCV RNA were 0.54%, 0.79% and 0.13%, respectively.

A structured hepatitis screening program at the primary care level has been successfully established and leads to age- and-sex-dependent large additional effects compared to routine care.

Strategies to eliminate chronic hepatitis B and C virus infection are country specific and vary between clinical scenarios. Our analysis proves the efficacy of a screening program by primary care physicians compared to routine care in a low-prevalence country. This program should be accompanied by additional efforts in risk populations like people who inject drugs who are under-represented in the current screening approach.
