[Clinical investigations: innovative management of data. Electronic Data Capture: IOStudy Office]

In the future clinical trials will increasingly be conducted using "electronic data capture EDC" in place of documentation on paper. The utilization of computer systems and special software programs will make quality optimization possible while speeding up the documentation and data processing. In the publication the software system IOStudy Office and its modules are presented. The facilitation of the data capturing process (physician), data monitoring (monitor), and project managment are discussed in detail.
