3

Problems of multicenter Studies

• Randomisation

• Response to major clinical Events

• Data Aquisition

• Input errors

• Supervision of follow-up Examinations


4

The WISEmed-Approach

• Avoid multiple Data Entry

• Use of WWW-Browsers as Client Interfaces

• Multilingual Client Interface

• Flexibility through Multi-Tier architecture

• Questionnaires subdivided into Moduls

11

Problems to be solved

• Study design not tool supported

• High number of dependencies between properties creation of questionnaires expensive


12

Perspectives

• Improved Data Quality

• Visualisation of certain Values´ History

• Continous Monitoring of Clinical Events

• Study Coordination less time consuming

• Patients could be incorporated more intensively

Procedure of -supported Studies

1. Medical Study Design •Study Design•Approval by Ethic Commission

3. Deployment of the Study

2. Technical Study Design •Layout of on-line Questionnaires•Creation of Modules•Programming of Systems Responses to Input Erors, Clinical Events etc.•according to Guide for good clinical Practice

4. Evaluation of Results •Technically possible at any time•Response to Clinical Events according

to Study Protocol

•Medical: as usual•Technical: support, generate Warnings
