Home-based color card screening for biliary atresia: the first steps for implementation of a nationwide newborn screening in Germany

Biliary atresia is a rare neonatal disease and the most common indication for pediatric liver transplantation. Kasai portoenterostomy is the initial treatment, aiming to prevent liver transplantation. Beyond age at Kasai, few prognostic factors are known. Multiple countries have established screening methods to reduce the age at Kasai and recent analysis shows significant better outcomes for screening cohorts. In 2016, we established a decentralized stool color card screening in Lower Saxony and we present our first 2 years of experiences. In cooperation with a major German health insurance company and the Medical Association of Lower Saxony, we established the screening project, printed 120,000 color cards, and distributed them to all maternity hospitals. Program advertises were printed in newspapers and medical journals. After the first year, the project was evaluated. Thirty maternity hospitals and local practitioners were contacted via telephone, Internet, intranet, and pediatric journals. One out of seventy-six maternity hospitals (1.3%) refused to participate in the screening. 30 hospitals (40%) were contacted and 93.5% of the interviewed staff reported that stool color cards were handed out regularly and discussed with the parents. Only 20% of local practitioners assessed neonatal cholestasis to be a relevant problem during daily practice, and 55% regarded a stool color card screening to be useful. In the second year, we extended the screening project to outpatient maternity clinics. Based on the responses of local practitioners, we regard the voluntary screening as insufficient and we have contacted the Federal Joint Committee for the initiation of a nationwide obligatory stool color card screening.
