This study introduces CaseBase, a Clinical Data Warehouse (CDW), to analyze real-world clinical data for improved patient safety. It enables detection of Adverse Drug Events (ADEs) by linking symptoms and medications.
Area of Science:
- Health Informatics
- Clinical Data Management
- Pharmacovigilance
Background:
- Chinese hospitals have vast clinical data from evolving information systems.
- Secondary data use, like Real World Evidence (RWE) studies, can enhance medical quality and safety.
Purpose of the Study:
- To describe CaseBase, a Clinical Data Warehouse (CDW).
- To introduce an Adverse Drug Event (ADE) signal detection platform built on CaseBase.
- To analyze and visualize drug-symptom relationships in clinical data.
Main Methods:
- CaseBase extracts structured symptoms and temporal data from clinical documents.
- It integrates medication data from the Computerized Provider Order Entry (CPOE) system.
- An ADE detection platform analyzes and visualizes drug-symptom relations.
Main Results:
- A prototype platform was evaluated in a large hospital.
- Initial results demonstrate the platform's capability in analyzing clinical data for ADE signals.
Conclusions:
- CaseBase facilitates secondary use of clinical data for research.
- The ADE detection platform shows potential for improving drug safety monitoring.
