摘要：Health information systems have the potential of improving the quality of healthcare and treatment procedures and supporting the physicians in their clinical diagnoses.Nowadays,evaluating the usability is widely accepted as a crucial factor in the acceptance and success of the interactive healthcare systems.The present study aimed to evaluate the usability of Ulite Software based on the ISO 9241 model.Method: This analytical-empirical study was performed in 2014.The target population consisted of 50 Utile Software users.The data were collected througha valid and reliable questionnaire containing questions from 10 valid and reliable questionnaires on the related field.The content validity of the questionnaire was evaluated and confirmed by the scholars and experts in Picture Archiving and Communication Systems (PACS) and the reliability was estimated through statistical procedures using Chronbach’s alpha Test (α=0.958 ).Data were analyzed in SPSS 20 using descriptive statistics and Smart-PLS version 3,using Structural Equation Method and Partial Least Square Approach.Results:The obtained results of the simultaneous analysis of all constructs regarding ISO 9241 model indicated a positive effect of “effectiveness” (P-value= 0.05) and “satisfaction” (P-value= 0.00) on the usability of web-based PACS,while the effect of “efficiency” (P-value= 0.68) was not confirmed.Conclusion: Usability evaluation of Ulite software in the demo version was performed based on the ISO 9241 model.Based on the results,it seems that this software has the necessary effectiveness and user satisfaction has been somewhat successful,but since the evaluation in the demo version aimed to purchasethe system and eliminate initial problems,we should focus on the deficiencies that decrease the efficiency of the system.
