To improve IT-support for biobank users by the Department of Medical Informatics (MI) a questionnaire was designed addressing topics regarding the provided software and the IT-support. Different stakeholders of supported projects were identified and the interviews were performed with five users. The developed questionnaire consisted of five sections and 50 questions. The results of the interviews showed an overall satisfaction with the software and the support. Differences were identified between "long-term" and "short-term" users. Most improvements should be made in the usability of the software. Furthermore, the interviewees showed a great interest in a user-group to discuss and compare the functionalities and workflows of the different research groups. The results of the interviews will be used to make a prioritized list of improvements for the software. After validating the questionnaire users of the other IT-Systems provided by the MI will be interviewed.
