Health information systems can improve the quality of services in healthcare. Evaluation of health information systems in hospitals is a very complex process, and it is more effective when different aspects are considered. The present work aims to develop an evaluation framework of an integrated HIS in order to improve the quality of healthcare services provided in Cyprus. Qualitative and quantitative methods were used, that measured three aspects of the system: Technology, human factor and organization. Preliminary results showed that while participants seem to agree with the potential benefits of the integrated HIS, safety of data within the HIS is seen as a problem. Qualitatively, the study pointed to 3 factors that might improve the current integrated HIS: Increasing interdisciplinary cooperation, training of staff, and upgrading the infrastructure. Further studies will provide a comprehensive picture for Cyprus, so that appropriate measures can be proposed and put in action.
