本研究主要目的為以Bhattacherjee和Premkumar(2004)的研究結果為基礎，並以信任關係加以擴充以探討那些因素會影響藥物辨識系統持續使用之意願，以及這些因素間隨著使用經驗的累積，各因素影響效果的改變。主要研究對象為國內南部某大學的進修部學生，資料搜集主要採問卷調查法並分兩次針對受測對象施測，統計方法採結構化方程模式，並以LISREL作為主要統計分析工具。透過本研究的探討，將可深入瞭解使用者對於藥物辨識系統之信任、認知有用性、期望差異、態度、滿意度以及持續使用意願等相關變數之影響關係。此外，本研究亦可驗證Bhattacherjee和Premkumar(2004)的研究發現外，並可比較不同系統特性之研究結果差異。而透過信任關係的探討也可進一步擴展此研究模式並將其應用於醫療領域，並有助於瞭解信任關係對於認知有用以及系統持續使用意願之影響，以強化對於影響系統使用者持續使用意願的瞭解，並釐清各變數對於持續使用意願的影響。而本研究所獲得的成果亦可作為後續研究者進行醫療資訊相關系統研究的參考，同時更可作為改善系統設計與使用的重要依據。 The purpose of this study is to explore the critical factors affecting the continuance of drug identification system based on an extended IS continuance model which is mainly coming from previous results of Bhattacherjee and Premkumar(2004) and the concept of trust. The survey methodology will be deployed with the subjects being the undergraduate students of the night program of a southern school in Taiwan. A two-stage data collection procedure will be conducted and the collected data will be analyzed using the structural equation model technique with LISREL software. The expected contributions of this paper can be summarized as follows. Firstly, this study can conduct an in-depth examination to investigate the potential factors (including trust, perceived usefulness, expectation disconfirmation, attitude, satisfaction, and continuous intention) affecting the continuance of drug identification system and the time effects on those investigated factors. The results of our study can provide several insights through the comparisons with previous findings of Bhattacherjee and Premkumar(2004). Secondly, the concept of trust, which is considered as an important factor for physician-patient relationship, used in this extended model can help us to extend this concept with the concerns of medical information and the relationships between trust and previous mentioned factors will be further explored. Finally, the results of this study will provide an important basis on investigating the critical factors influencing the use of medical related system and it can also be used as useful suggestions for system improvement.
