Goals

In the management process of clinical trials different physicians (e.g. pathologist, radiotherapist) and medical facilities are involved. These experts handle a large amount of data which is not uniformly defined and documented. To overcome the problem of inconsistencies in the understanding of medical terms and interpretation of data it is necessary to build up a semantically founded data dictionary.

In the first step we have implemented a data dictionary, which is substantially based on an entity relationship model with concepts, relations and descriptions. In the second step we develop a data dictionary with different context-dependent descriptions of concepts and context-dependent relations.

Through the usage of a common Data Dictionary for all physicians and medical facilities involved we want to achieve the following goals:

• Reusability of terms and their meanings e.g. in the definition of new trials
• Harmonization of the study-centre databases within the Lymphoma Alliance
• Quality assurance in carrying out clinical trials
• Uniform reference of terms for all trial-specific applications e.g. entry masks
• Uniform reference of terms for the definition of Standard Operating Procedures (SOPs) within the Lymphoma Alliance
• Harmonization of trial protocols and case report forms
