Factors affecting the usability of laboratory information system used in Libyan hospitals by using technology acceptance model (TAM

Information system research can help the industry improve its service management and coordination via a successful information technology implementation. Many hospitals have implemented various healthcare information technologies, such as laboratory information system, in order to deal with paperless and filmless operation requirements. A laboratory information system is necessary to manage the flow of information between health care providers, patients, and laboratories and it should be designed to optimize not only laboratory operations but also personalized clinical care. The objective of this study is to analyze and integrate several factors impacting the acceptance and usability of the laboratory information system used at Libyan Hospitals. In the light of the technology acceptance model, and extending it to seven external variables including computer anxiety, self-efficacy, user interface design, training, age, educational level and system experience. For this purpose, quantitative research was chosen for examining the research model, and the data were obtained from technicians, chemists, and physicians using the laboratory information system. The sample size is (N=250); therefore, the data were analyzed using structural equation modeling to analyze the relationship between explanatory factors and actual use of the laboratory information system. SmartPLS software was utilized to analyze the data and test the hypotheses. The results indicate that the actual use of the laboratory information system significantly and positively affected by behavioral intention, education level, interface design, perceived usefulness, perceived ease of use, training, system experience. The implications of the outcomes are discussed, and suggestions for future research are made.
