以資訊系統成功模式探討醫師使用行動醫療之重要因素

Most accredited regional hospitals in Taiwan have built up comprehensive Hospital Information System (HIS). Recently, based on the original infrastructure of information and communication system and government support, some hospitals actively developed Mobile Health information system (mHealth). By using mHealth, clinicians can get real-time patient's information at any place of hospital to enhance administrative efficiency and improve healthcare quality. Our study subjects were physicians who have used the mHealth at a northern teaching hospital of Taiwan. We used ＂The DeLone and McLean Model of Information Systems Success＂ as the study framework and the questionnaire was developed accordingly. Questionnaires were distributed to 308 physicians, 126 out of 129 returned were valid, and the response rate was 40.91 %. The results showed that Task urgency of system quality (β=0.225 **, t=2.594), Format of information quality (β=0.336 * *, t=2.591), and Empathy of service quality (β=0.336 **, t=3.294) had significantly positive effect on physicians' satisfaction with mHealth. Moreover, the user satisfaction had positive effect on usage intention (β=0.635 ***, t=10.329) and personal benefit (β=0.294 ***, t=3.735). Ultimately, the usage intention had positive effect on personal benefit (β=0.633 ***, t=8.232) of mHealth. Hospitals have invested lots of money and manpower to set up the mHealth for improving administrative efficiency and quality of care. The function quality, information quality, and service quality of mHealth should satisfy physicians' need, and then achieving the goal of personal benefit. Therefore, hospitals should strive for meeting physicians'' satisfaction while developing mHealth to install the system successfully.
