Analysis of the quality of hospital information systems in Isfahan teaching hospitals based on the DeLone and McLean model

Abstract

BACKGROUND: Quality is one of the most important criteria for the success of an information system, which refers to its desirable features of the processing system itself. The aim of this study was the analysis of system quality of hospital information systems (HIS) in teaching hospitals of Isfahan based on the DeLone and McLean model. MATERIALS AND METHODS: This research was an applied and analytical-descriptive study. It was performed in teaching hospitals of Isfahan in 2010. The research population consisted of the HIS's users, system designers and hospital information technology (IT) authorities who were selected by random sampling method from users' group (n = 228), and system designers and IT authorities (n = 52) using census method. The data collection tool was two researcher-designed questionnaires. Questionnaires' reliability was estimated by using Cronbach's alpha was calculated. It was 97.1 for the system designers and IT authorities' questionnaire and 92.3 for system users' questionnaire. RESULTS: Findings showed that the mean of system quality score in a variety of HIS and among different hospitals was significantly different and not the same (P value >/= 0.05). In general, Kosar (new version) system and Rahavard Rayaneh system have dedicated the highest and the lowest mean scores to themselves. The system quality criterion overall mean was 59.6 for different HIS and 57.5 among different hospitals respectively. CONCLUSION: According to the results of the research, it can be stated that based on the applied model, the investigated systems were relatively desirable in terms of quality. Thus, in order to achieve a good optimal condition, it is necessary to pay particular attention to the improving factors of system quality, type of activity, type of specialty and hospital ownership type.
