This paper describes the development of a questionnaire for evaluating usability during EHR system procurement (DPUQ). Established usability questionnaires can be used to gather user feedback after using the systems. However, during procurement, experimenting with real system use is practical only with a limited number of system candidates. There is a need for less resource-demanding usability evaluation in the early stages of procurement in cases with several vendors. DPUQ has been designed for usability evaluation by end-users during special scenario-based vendor demonstrations. The questionnaire includes three sets of questions to be used during and after the vendor demonstration. DPUQ delivers specific usability scores and can be used to compare system candidates in procurement complementing other evaluation methods.
