QuesGen

QuesGen is a web-based data management system uniquely developed for academic and commercial research studies and clinical trials. The data capture required for each study is custom built to address each study's specific needs. The system can typically be configured in about a week, depending on project requirements. The QuesGen application is reliable, secure and flexible.

Overview

QuesGen offers a patient recruiting module that is unique to each study. First, an informational website is created for the study. From that site, secure custom screening surveys can be sent to interested participants. Thorough screening using inclusion and exclusion queries, skip logic and necessary calculations are written into each survey based on study protocols. This has proven to be a valuable tool to research teams by saving significant man hours in traditional recruiting phone tag. A number of UCSF studies are using this service. See sophie.studysites.net or vigor.studysites.net for examples. QuesGen's demonstration site can be viewed: http://demo.studydata.net

In addition, QuesGen provides expert information on any aspects of data management, we would be happy to do so. We have extensive background in relational database creation and administration as well as years of working with research teams in all aspects of study design.
