Practical implementation of a bridge between legacy EHR system and a clinical research environment

Area of Science:

• Health Informatics
• Clinical Research Informatics
• Data Interoperability

Background:

• Traditional legacy Electronic Health Record (EHR) systems often lack the advanced functionality required for seamless clinical research.
• Integrating Clinical Information Systems (CIS) with Clinical Research Environments (CRE) presents a viable solution to overcome these limitations.

Purpose of the Study:

• To describe the implementation of a CIS-CRE bridge at the University Hospitals of Geneva.
• To demonstrate how this integration enhances functionality for clinical research.

Main Methods:

• Mapping extracted data from the CIS to the i2b2 Clinical Data Warehouse.
• Implementing a system to facilitate interoperability between CIS and CRE.

Main Results:

• Successful establishment of a functional bridge between the Clinical Information System and the Clinical Research Environment.
• Demonstrated ability to map CIS data effectively into the i2b2 Clinical Data Warehouse.

Conclusions:

• The implemented CIS-CRE bridge provides essential functionality not easily achieved with legacy EHR systems.
• This approach successfully enables interoperability for the Clinical Research Environment, facilitating research endeavors.
