Introduction: Laboratory information system (LIS) is one of the key components ofhealthcare information system (HIS). It can help the healthcare providers to delivery faster,easier, and more efficient healthcare services. Acceptance and success of LISs depend on theappropriate designs of user interface of these systems. Therefore, this study was conductedaiming to focus on the end-user usability evaluation of LIS.Methods: This is a descriptive cross-sectional study. It was conducted on the LIS embeddedinto a HIS used in Faghihi Hospital affiliated to Shiraz University of Medical Science, Iran.The target population was all of 80 pathologists and laboratory technicians of this hospitalwho worked with LIS. We used the questionnaire of Usefulness, Satisfaction, and Ease of Use(USE) to evaluate the LIS. The descriptive data were analyzed using SPSS22; the reliability andvalidity of the measures and model were determined using Smart-PLS version 3 with PartialLeast Squares.Results: The result of all the constructs with regard to USEQ model demonstrated apositive effect of “Usefulness” (t-value=2.08), “Satisfaction” (t-value=1.89) and “Ease of use”(t-value=5.05) on the usability of the LIS.Conclusion: The USEQ model proposed was a valid and reliable instrument and couldbe used by researchers. The LIS was usable, and end-users could interact with this systemwithout any effort. Therefore, healthcare professionals can perform their tasks better with thissystem and make appropriate diagnostic and therapeutic decisions for their patients.
