Metadata exchange between clinical study software systems is feasible using the ODM standard. This enables system-independent data transfer with minimal effort, facilitating collaboration across research centers.
Area of Science:
- Clinical research informatics
- Data standards in clinical trials
Background:
- Clinical study software systems often operate independently.
- Interoperability challenges hinder seamless data sharing and collaboration.
- Standardized metadata exchange is crucial for efficient clinical research.
Purpose of the Study:
- To assess the feasibility of transferring entire clinical studies between independent software solutions.
- To determine if software-independent metadata transfer is possible without programming.
- To evaluate the use of routinely used clinical research software for data exchange.
Main Methods:
- Utilized the ODM (CDISC) standard for study metadata transfer.
- Employed MACRO (InferMed) and XTrial (XClinical) study software.
- Used XML-Spy and ODM-Checker for validation and modification of ODM export files.
Main Results:
- Successfully demonstrated the technical feasibility of system-independent metadata exchange.
- Achieved interchange of study metadata between two systems with minimal expenditure.
- Required minor corrections and a vendor extension for a syntactically correct ODM file.
- XTrial correctly displayed the study and all data fields after modifications, though CRF appearance differed.
Conclusions:
- The ODM standard is suitable as an exchange format for clinical studies between different software.
- Enables new collaborative possibilities, such as joint creation of electronic protocols and CRFs.
- While ODM represents study data completely, it lacks information on CRF data field representation.

Clinical Trials: Overview
Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.

Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
