The aim of this study is to explore the origin of expectations among healthprofessionals and how they influence the implementation of health informatics systems. By reviewing literature we examine whether it is possible to affect these expectations prior to imple-mentation of health informatics systems. Data were analyzed using a grounded theory approach based on a social constructivist perspective. The approach originated from an idea that missing clarification of healthprofessionals expectations is a problem when health informatics systems are being implemented. If mixed, wrong or unrealistic expectations exist it can lead to rejection of the systems. Results: We found that prior to implementation, working with expectation from different perspec-tives: individual, leadership, organizing and organization can be of crucially significance and maybe even cause user acceptance or boycott of the system. • Focus on users expectations and user involvement should be present from the design phase thru to the completion of the project. • By examining the user’s expectations the management should try to match the expectations to the visions and by communication helping the clinicians to form realistic expectations. • One of the main reasons of resistance to change in health informatics has shown to be caused by a disparity between what the clinicians expected and what subsequent was experienced in the clinic. • Management should focus on leadership as it involves both leaders and em-ployees in determining common goals and thereby preparing of a clear vision which can be understood of the clinicians. • Evaluation of culture can predict changes are received by the clinicians. Culture appeared to be decisive factor for implementations processes and should there-fore be watched closely to judge the need and possibilities for adjustments. • Confidence between management and clinicians is a crucially factor to promote the processes in the organization. • Timeframes and realistic goals should be promoted to maintain a atmosphere of optimism • Expectations to health informatics depend on where people are placed in the organization and whether they have previous experience with information tech-nology or not. Final our investigation and discovery has inspired us to expanding the FITT-model by involving the socio-technical perspective in the form of the SCOT-model’s approach on how to creating accept of new technology together with technology as ecology.
