Table 4 Summary

• Today hospitals depend on an effective and efficient IT environment to manage the complex requirements in every day work. It is known that IT adds an important value proposition to the hospitals.

• Usability evaluations are necessary to estimate the quality of interactive IT-systems in clinical environment, while a lack of usability is one of the main reasons for problems with IT implementations.

• System adaption depends on the users' attitude, which is influenced by the status of usability. Therefore it is important to evaluate not just from the experts' point of view, but also to pay attention to the direct users of clinical-IT.

• The survey offers the largest national usability data base of Hospital-IT in Germany so far. It allows the comparison of various clinical-IT systems and demonstrates evaluation from different user perspectives.

• The findings of the study show that software ergonomic of clinical-IT is in the range of standard software, while specialised systems are more likely to receive better results than general systems. The effectiveness results show that all systems support the working processes, but also points out the differences between the diverse systems.

• The study reveals several starting points for further studies

• The available results of Usabil-IT provide an insight into the current state of usability of clinical IT. They can be used for developing and evaluation processes in the future.
