This paper is based on an interview study with 19 resident, specialist and senior physicians. The study was initiated by a Swedish Hospital management to investigate physicians' attitude towards their EPR (Electronic Patient Records) and give recommendations for improvement in organization, development, deployment and training. The management had experienced that the physicians were unwilling to take part in the EPR deployment process and simultaneously complained about the low usability and potential safety risks of the systems. The study shows that the EPR must be considered a shared responsibility within the whole organization and not just a property of the IT department. The physicians must consider, and really experience, EPR as efficient support in their daily work rather than something they are forced to use. This includes considering work with the EPR as an important part of their work with patients.

The authors have recently experienced difficulties in the transfer of design knowledge from designer to developer.The CHILI application in particular is the successor of an another teleradiology application where the initial design and specification phase did not guide the implementors enough, resulting in a system which was different from the expected one. [2] The focus of this paper is to informally discuss the design process and the key design decisions made for the CHILI application. DESIGN PROBLEMS Image SizeIt is well known in the image processing community that there is too little space vertically on the screen. This is caused by the fact that most screens have a higher resolution horizontally which usually makes the resizing of images limited by vertical space. The images in radiology are normally 512 x 512 pixels, so the optimal area for images has the shape of a square, which means that one can resize images more naturally simply by a scaling factor. The user's general wish is to have the image area as large as possible. ConstraintThe obvious restricting factor is that we may not simply enlarge the images as much as the screen size allows, because we still need a system which is possible to use in an efficient way. E.g. we still need to be able to view patient data efficiently, search and navigate the patient database, etc. Usability IssuesAs the case is for most computer applications, the end-user community is heterogeneous. This is not only caused by different levels of computer experience, but also by the fact that there will be different categories of users targeted by the system. These categories range from general practitioners to expert radiologists to technical staff. ConstraintThe mixed user community is of more concern than might first be thought at; designers are limited in the work process by having to make a system that novice users are able to use. It is difficult to support efficiency of work for expert users at the same time. A Teleradiology System Design Case ABSTRACTThis paper describes the teleradiology application CHILI from the graphical user interface point of view. We present the most important design decisions taken during the construction of the system and discuss different methods and techniques that affected the design process.Some non-standard design principles are presented, and the reasons behind them. Several of the basic GUI constructions used in the CHILI application are somewhat similar to those seen in Sun's HotJava Views™ [3]; the application lacks the traditional connection to the desktop metaphor and has instead a work task oriented approach.
