ClinConnect Summary

The Biliary Atresia Research Network Northeast is a clinical trial that is looking at the health records of children with biliary atresia, a serious condition that affects the liver and bile ducts. The goal of the study is to gather information about how children with this condition are managed and what factors lead to better health outcomes. By understanding these factors, researchers hope to improve care for future patients and make better use of healthcare resources.

To participate, children must be 12 years old or younger and have received care related to biliary atresia at one of the hospitals involved in the study between January 1, 2012, and December 31, 2021. This includes those diagnosed with biliary atresia based on specific medical codes. If you know a child who fits this description, they might be eligible to help researchers learn more about this condition. Participants won't need to do anything special, as the study is based on reviewing existing medical records to gather valuable information.
