Abstract
INTRODUCTION AND OBJECTIVES: The implantation of hospital information systems (HISs) has grown dramatically in recent years. Understanding the success rate of HIS is key in health organizations. In this study, a validated questionnaire for HISs evaluation based on the Information System Success Model (ISSM) has been provided. In addition, the HIS success rate was determined. MATERIALS AND METHODS: The current study was conducted at one of the largest teaching hospitals in eastern Iran. The 44-items questionnaire was developed for data gathering. The questionnaire covered ISSM dimensions, which include analysis of quality system, quality of information, quality service, system use, usefulness, satisfaction, and net benefits. Content validity, constructs validity, and reliability of the ISSM questionnaire was measured. HIS success rate has been determined and categorized based on users' perspective as follows: appropriate (75%≤HIS success rate), moderate (50%≤HIS success rate<75%), low coverage (25%≤HIS success rate<50%), and poor (coverage rate<25%). RESULTS: In total, 253 users participated in the study. The ISSM questionnaire was validated by an expert panel with CVI: 85.12% and CVR: 88.22%. The overall Cronbach's alpha value of the instrument was determined as 92.2%. Nine factors with eigenvalues greater than 1.00 were identified, jointly accounting for 66.91% of the total variance. The value of KMO was.866 showed that the sample size was adequate for factor analysis. The highly significant Bartlett's test (p<0.000) indicated that variables were correlated and the factor analysis was appropriate. Our results demonstrated that the total mean of HIS success was "moderate" base on the users' point of view. CONCLUSIONS: The findings of the current study, provide valuable scientific evidence for key affecting factors on hospital EHR in Iran as a developing country.
