Biliary atresia is a life-threatening disease that affects newborn babies; it requires early surgical treatment. Researchers from Taiwan performed a retrospective cohort study to evaluate the effectiveness of stool color card screening for early diagnosis. They found that the median age at first admission for patients with suspected biliary atresia decreased from 47 to 43 days and the median age for surgery decreased from 51 to 48 days after the implementation of stool color card screening. The researchers conclude that this screening seemed to increase patients' and physicians' awareness of biliary atresia.
