Assessment and Comparison of Hospital Information Systems in Isfahan based on the DeLone and McLean Model Adjusted

Hospital Information Systems (HISs) have positive effects on patient's treatment process and organizational function. Therefore, it is necessary to evaluate the quality of services provided by such systems. The aim of this study was to assess and compare HISs in Isfahan hospitals based on the DeLone and McLean Model adjusted. This was an applied, analytical-descriptive study performed in public and private hospitals of Isfahan in 2010. Research population consisted of system users and designers and authorities of hospital information technology, directors and managers of official and clinical departments equipped by such systems. While users were selected by random sampling (n = 300), census method was used for the other two groups (n = 212). Data was collected using a questionnaire designed by the researcher based on three criteria (system quality, information quality and user satisfaction). It was adjusted to DeLone and McLean model. Content validity of the questionnaire was verified by faculty members as well as computer science specialists. The reliability of the questionnaire was estimated by Cronbach's alpha coefficient and data was analyzed by SPPS. According to our findings, mean scores of system quality, information quality and satisfaction were significantly different between various kinds of HISs, as well as between different hospitals (P < 0.05). Total mean scores of system quality, information quality and satisfaction for all HISs were 58.6, 60.8 and 61.2, respectively. According to the results of this research, the criteria of HISs have been implemented in a rather optimum condition. Thus in order to reach desirable conditions, it is necessary to pay particular attention to factors improving system quality, information quality, type of specialty in a hospital, and user's expectations and specialty when designing HISs.
