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.enMediCloud system; PharmaCloud; electronic medical records; health information exchange; health information systems; technology acceptance model; technology continuance theory[SDGs]SDG3health insurance; health monitoring; health services; perception; public health; technological development; adult; article; controlled study; electronic medical record; expectation; human; medical information system; national health insurance; outpatient department; path analysis; satisfaction; structured questionnaire; Taiwan; theoretical study; health personnel attitude; physician; public health; questionnaire; Taiwan; Taiwan; Attitude of Health Personnel; Health Information Exchange; Humans; National Health Programs; Physicians; Surveys and Questionnaires; Taiwanjournal article10.3390/ijerph18168415344441672-s2.0-85112129275https://scholars.lib.ntu.edu.tw/handle/123456789/582748
