Collection of data in clinical studies via Internet.

This paper describes a system enabling data collection in multicenter clinical trials via WWW and Internet. The form-based data entry is based on HTML documents with JavaScript linked to a relational database (mSQL) via a cgi program (w3-msql). The design has been applied to a multi-national study in acute abdominal pain, for which eight clinical forms have been developed. The system is now in test use and experiences with this approach are presented.
