What this trial studies

This observational study involves a multi-center retrospective chart review aimed at compiling a comprehensive data repository of the management and outcomes of children diagnosed with biliary atresia across various pediatric hospitals in the Northeast. By gathering clinical data from hospitals, including those with low patient volumes, the study seeks to identify specific factors that contribute to improved patient outcomes. The data will be de-identified and stored in a HIPAA-compliant repository, allowing researchers to analyze differences in management and outcomes for this rare condition. The study covers cases from January 1, 2012, to December 31, 2021, focusing on children aged 12 years and younger.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 12 years and younger who have had a healthcare encounter related to biliary atresia at a participating institution during the specified study period.

Not a fit: Patients aged 13 years or older during the study period will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies and outcomes for children with biliary atresia.

How similar studies have performed: While studies on biliary atresia exist, this approach of pooling data from multiple low-volume hospitals is relatively novel and aims to fill a significant knowledge gap.

  * Q44.2 Atresia of bile ducts
  * Q44.3 Congenital stenosis and stricture of bile ducts

* No diagnosis of biliary atresia
* History of biliary atresia without any episodes of care related to biliary atresia during the study period (e.g. a teenager with history of BA who underwent Kasai procedure as an infant and has no current issues related to their BA and is receiving care for an unrelated reason)
