Abstract
The purpose of this research study is to contribute to the development of an instrument for the evaluation of Greek Hospital Information Systems. Information technology has rapidly penetrated into the healthcare sector with integrated information systems, and it has been proved that it can lead to better decision support, organizational support and even influence the patient outcome. This is why the evaluation of HISs is a very critical issue. After an extended and systematic review of the existing literature on the basis of published studies, user satisfaction was chosen as the measurement of IS success. Furthermore, a research was conducted in order to detect the factors that affect the IS user satisfaction. This study was based on the DeLone and McLean’s (2003) model of IS success and, also, on widely validated user satisfaction models. System quality, information quality, service quality and user background were selected in order to measure user satisfaction. Moreover, fourteen factors were chosen with corresponding items that according to the literature measure the above four factors. A hypothetical research model was designed and based on this the questionnaire that was used in the research was generated. The questionnaire was distributed at 4 Greek hospitals; the General Hospital of Heraklion Crete “Venizeleio-Pananeio”, the General University Hospital of Alexandroupoli, the General Hospital of Thessaloniki “Papageorgiou” and, finally, the General Hospital of Thessaloniki “Georgios Papanikolaou”, that agreed to participate to the survey. 100 completed questionnaires were collected. The statistical analysis included factor and reliability analysis in order to estimate the adequacy of the measurement model and, after that Structural Equation Modeling was performed to test the structural models fit. The conclusion is that user background, information quality and service quality directly and positively affect user satisfaction confirming the initial three hypotheses (H1, H3, and H4). The diversity concerned H2 which have shown that system quality influence user satisfaction only indirectly through information quality and not directly as it was initially stated.
