The COVID-19 pandemic has had an immense impact on healthcare systems worldwide particularly in terms of infection control measures. Hospital Sungai Buloh has implemented a novel walk-away queuing system for outpatient clinics, namely the iQMS. This system enables infection control via facilitating social distancing whilst waiting for their appointments and affords waiting location flexibility. However, the factors affecting outpatients’ intention to use the iQMS is yet unknown, and this is the subject of this study. The Technology Acceptance Model (TAM), Perceived System Usability and sociodemographic factors were used to study this relationship. This study used a cross-sectional quantitative design utilizing a self-administered questionnaire to obtain data. The questionnaire comprised of sociodemographic factors, Perceived Usefulness, Perceived Ease of Use, Intention to use the iQMS and Perceived System Usability. Two hundred and fifty-four respondents completed the questionnaire, corresponding to a response rate of 87.8%. The questionnaire showed satisfactory construct validity, discriminant validity and reliability. Perceived Usefulness and Perceived Ease of Use had a significant impact on the Intention to use the iQMS, while Perceived System Usability showed a moderate positive relationship with the Perceived Ease of Use. Sociodemographic factors did not influence the Intention to use the iQMS. In conclusion, the Intention to use the iQMS is associated with the Perceived Ease of Use and Perceived Usefulness of the system.
