Abstract: This study aimed to investigate the factors influencing physicians use of the PharmaCloud system in Taiwan through Technology Continuance Theory (TCT) and to construct a TCT-based structured questionnaire to demonstrate the attitude and behavior of physicians in the Taiwanese medical system. It focused on investigating “confirmation”, “perceived usefulness”, “perceived ease of use”, “attitude”, “satisfaction”, and “continuance intention” towards the preload-based comparison and manual search in PharmaCloud by attending physicians during their outpatient clinics. Path analysis was used to analyze the cause and effect relationship between variables. This study collected 528 valid questionnaires and the results of path analysis found that factors affecting physicians’ continued use of preload-based comparison in PharmaCloud included “perceived usefulness”, “satisfaction”, and “attitude” (all p < 0.001); however, factors that influenced physicians’ continued use of manual search in PharmaCloud were only “satisfaction” and “attitude” (all p < 0.001). Additionally, the effects of “perceived usefulness” and “perceived ease of use” on “satisfaction” could only be seen in preload-based comparison in PharmaCloud. In conclusion, when physicians’ actual use of PharmaCloud met their expectations, physicians had higher levels of confirmation and better perceived usefulness, which naturally increased their satisfaction and attitude towards PharmaCloud and positively prompted them to continue using it.
