An assessment and comparison of information quality of hospital information systems in medical-teaching hospitals of the city of Isfahan based on delone and McLean's modified model
Background: Taking the positive effects of the hospital information systems on patients' treatment process and organization's function into account, it is necessary to evaluate information quality provided by such systems. Hence, the aim of this study was to assess and compare information quality of hospital information systems in medical- teaching hospitals of Isfahan based on the DeLone and McLean's modified Model. Methodology: This research was applied and analytical-descriptive in nature and was performed in medical-teaching hospitals of Isfahan in 2010. Research population consisted of hospital information system's users, system developers and IT authorities selected by random sampling method. Data collection instrument was self-designed questionnaire. Questionnaires' reliability was estimated by using Cronbach's Alpha coefficient that was found to be 94.08 and 96.8 for system users' questionnaire and system developers and IT authorities' questionnaire, respectively. Results: According to the findings of the study, the difference between the mean scores gained for information quality of all kinds of HISs and different hospitals were statistically significant, i.e. they were not the same (p<0.05). Generally, Kowsar system (new version) and Rahavard Rayaneh system gained the highest and lowest mean score, respectively. The total mean scores obtained for observing the standards stipulated for information quality was 60.2 for all hospital information systems and 60.8 for different hospitals, respectively. Conclusion: According to the results of the research, it can be inferred that based on the applied model, the levelof observing the criteria of hospital information system was rather optimum. Thus, in order to reach a completely optimum condition, it is necessary to pay particular attention to the factors improving information quality, type of activity, type of specialty and property type
