Usabilitytest of five medication management systems

In Denmark the five regions have implemented different electronic health record (EHR) solu-tions developed by different vendors consequently resulting in different working procedures in each region. The systems have been tested according to functionalities, but have not been usability tested to the same depth and using the same methods to allow comparison. Ten physicians were therefore recruited to perform a usability test in a cross-over design, both testing their own system and an unknown system. This study focuses on the methodology to conduct a usability test in the five different systems focusing on the medication module.
