延伸科技接受理論模型探討醫師對於健保雲端藥歷的行為意圖

Physicians’ behavioral intentions toward the NHI PharmaCloud: An extension of the technology acceptance model

健保雲端藥歷在健康照護上是為極重要的角色，可提供病人用藥相關資訊來支援健康照護應用，包含：診斷與治療。儘管健保雲端藥歷具有很大的潛在優勢，但很少有研究探討影響醫師意圖使用雲端藥歷的前因。因此，本研究提出一個整合性科技接受模型來解釋醫師意圖使用健保雲端藥歷。本研究採用問卷調查法以醫師為研究對象，問卷發放予南部某區域醫院有使用雲端藥歷經驗的醫師，共回收有效問卷60 份，再以結構方程模式之最小平方法來驗證假說。研究結果發現：知覺有用性、知覺易用性以及制度信任顯著影響醫師對雲端藥歷的使用意圖；再者知覺易用性顯著影響知覺有用性。從實務的觀點，瞭解影響醫師使用健保雲端藥歷的影響因素，可幫助中央健康保險署與醫院管理者發展擬定適合管理策略以降低使用者抗拒以及避免對健康政策之影響，並增益學術界瞭解醫師使用健保雲端藥歷之重要參考依循。

Taiwan’s National Health Insurance (NHI) PharmaCloud has played a crucial role in healthcare by providing patients’ drug-related information in order to support diagnosis and treatment. Despite its great potential, however, few studies address the antecedent factors of physicians’ intentions to use PharmaCloud. In this study, we propose an integrated technology acceptance model to explain physicians’ intention to use PharmaCloud. We conducted a field survey in a regional hospital in Southern Taiwan to collect data from physicians who had experience using PharmaCloud, using a valid sample of 60 physicians for data analysis. To test the proposed research model, we employed structural equation modelling using the Partial Least Squares method. The study’s findings show that perceived usefulness, perceived ease of use, and institutional trust have significant effects on physicians’ intentions to use PharmaCloud. Moreover, perceived ease of use appears to significantly affect perceived usefulness. From a practical standpoint, understanding why physicians use PharmaCloud can help the NHI and hospital administrators to devise appropriate management strategies in order to minimize user resistance and thus avoid the effects of such resistance on healthcare policy. Furthermore, the results of this study indicate that our research model effectively predicts the intention of physicians to use PharmaCloud and provides valuable implications for academics.
