Acceptance of Hospital Information System among Medical Records Users Based on Technology Acceptance Model

Technology Acceptance Model is used to describe human behavior in relation to the information systems. Concentrating on the model, the present research tries to recognize and examine the factors affecting the hospital information system in the teaching hospitals of Tehran University of Medical Sciences. This paper was a cross- sectional and correlation study conducted in 1390 AH (March 19, 2011 to March 20, 2012). The research population covered 185 respondents including the medical records personnel of the teaching hospitals of Tehran University of Medical Sciences. The data were gathered using a questionnaire (developed by the author comparing the similar studies), which validity was confirmed by a committee of experts and the reliability was calculated (before the study began) using a Cronbach α (α=0.93) in a 50 people sample. The descriptive statistics and non-parametrical analysis of the Spearman rank correlation was applied to the data analysis using an SPSS18. The findings suggested a positive correlation individually between Behavioral Intention and the factors of perceived usefulness (Pvalue<0.01, r=0.521), perceived ease of use (Pvalue<0.01, r=0.469), self efficacy (Pvalue<0.01, r=0.548), end user support (Pvalue<0.01, r=0.399), social norms (Pvalue<0.01, r=0.383), Trust (Pvalue<0.01, r=0.501), job relations (Pvalue<0.01, r=0.587), and training (Pvalue<0.05, r=0.263), but no correlation was seen between Behavioral Intention and the factors of anxiety (Pvalue<0.01, r=0.150), voluntariness (Pvalue<0.01, r=0.147), and facilitating conditions (Pvalue<0.01, r=0.046). Based on the results obtained from this study, it could be concluded that pay more attention to the factors affected on users’ acceptance may caused to more usage of new technologies in medical records departments. In addition, the results of such studies could be useful in terms of designing new systems to make better coverage on users needs.
