Content• Introduction / Background• Description - flow of ADR reports• Advantages I• Demonstration• Important features of the system • Advantages II• Future possibilities• If interest
– Technical description of the system
• Questions
Background I
• WHO report format 1981 –– NC have to comply
– Lack of computer support at many NC
– WHO paper forms accepted
• ICH – E2B format introduced – Harmonization
– Greater complexity
– UMC Vigibase 2002
Background II
• NC choices– System based on international standard-E2b-
or not
– Buy commercial software • Expensive• Not directly applicable
– Develop inhouse• Complicated• Time consuming
Background III
• SwissMedic – HIS -> HIS 2000– Vigibase Online
• Version 1.0 (2003-07-01)– No local database – Uppsala-based xml-database
• Versión 2.0 (2003-11-01)– Built on E2b-standard
– Text based to improve performance
Vigibase Online
• Fully implemented in Switzerland• Used for a year by Ghana as pilot
country• Morocco latest live user • Pilot phase with Swiss company

Important features
• Built on E2b standard• Built-in error handling/validation
– adapted dependent on category of user/assessor
• Download to local PC possible• Built-in support for several languages• Tools for statistics and analysis• Complete audit trail on all fields• Performance dependent on speed of
internet connection
Advantages II (technical aspect)
• One server installation• No client installation• Unlimited numbers of users• Sharing of costs
– development
– maintenance
How to get started
• Test site (not for reporting)• Get user’s guide from the UMC• Request national data base to be
established by the UMC. Provide identity of users
• Users receive username & password• Free use of system for 6 months• Annual fee of USD1600 thereafter
The Future
• Same system for several authorities• Facilitate communication• A direct link with other system
– SIGNAL document
– VigiSearch
• Useful (with adaptation) for other types of organizations; – Pharmaceutical companies
• Simple linking to other reporting tools
