Implementation of a platform dedicated to the biomedical analysis terminologies management

Area of Science:

• Medical Informatics
• Clinical Laboratory Science

Background:

• Assistance Publique - Hôpitaux de Paris (AP-HP) is implementing a unified laboratory management system (LMS) across 12 hospital groups.
• Acquisition of a biological analysis dictionary, interfaced with the international LOINC nomenclature, was the initial phase.
• The dictionary was developed collaboratively with experts from all biological disciplines.

Purpose of the Study:

• To describe the implementation of a platform for publishing and maintaining the AP-HP laboratory data dictionary (AnaBio).
• To address data complexity and volume challenges in laboratory terminology management.
• To enhance previous spreadsheet-based tools by developing a dedicated terminology management platform.

Main Methods:

• Implementation involved three key steps: modeling, data migration, and integration/verification.
• A core model was developed to ensure interoperability regarding data exchange standards and dictionary evolution.
• The platform was designed to manage the AP-HP laboratory data dictionary.

Main Results:

• The AnaBio platform implementation was completed within one year.
• Structuring data representation led to significant data quality improvements, affecting over 10% of the data.
• The platform is now operational in 21 AP-HP hospitals, serving 165 laboratories.

Conclusions:

• The implemented platform successfully addresses the need for robust laboratory data dictionary management.
• The project enhanced data quality and interoperability within the AP-HP laboratory network.
• AnaBio provides a scalable solution for maintaining and publishing laboratory data standards.
