Laboratory Information Systems (LISs) can exchange data and increase users' performance with accurate information and a low error rate. A good usability system should have a positive impact on quality of care and increases patient safety. This study aims to measure the level of the usability of the LIS system in Benghazi public hospitals. The LISs will be tested using QUIS and SUS usability tests. A survey was distributed among LISs users in public hospitals in Benghazi. Poor usability was observed; the SUS score was 65.2 which were significantly lower than the benchmark (P < 0.05). Years of experience using the LIS had influenced SUS scores; users who had less than one year experience evaluated the SUS with a score 55; while the respondents with four or more years of experience evaluated the SUS with a score of 70.2. Moreover, the screen section had a good rating as the respondents were satisfied with it. However, the system speed was slow. Based on the results of this study, the usability of LISs needs improvement, and IT developers should focus on the system speed.
