Tracking Change From Baseline in Total Bilirubin (NCT04280705)
Change From Baseline in Total Bilirubin (NCT04280705) - FEvIR EvidenceVariable
Summary
This evidence variable (NCT04280705) tracks the change in total bilirubin levels over time, using Day 1 as the baseline measurement for inpatient participants. It aims to standardize clinical trial data into FHIR format, enhancing healthcare interoperability.
Details
This document provides the definition details for the evidence variable titled 'Change From Baseline in Total Bilirubin (NCT04280705)' on the Fast Evidence Interoperability Resources (FEvIR) Platform. This variable describes how total bilirubin levels were measured in a specific clinical trial, using Day 1 as the baseline. Specifically, blood samples were collected during hospitalization on Days 1, 3, 5, 8, and 11, and post-discharge on Day 15 and 29. The data definition is structured as an FHIR EvidenceVariable resource, enabling the handling of longitudinal biomarker measurements in a standardized format. This ensures interoperability when comparing and analyzing temporal changes in biomarkers (total bilirubin) collected across different systems or studies. The platform utilizes FHIR and EBMonFHIR IG, contributing to the standardization and exchange of structured medical data.
