Background: Electronic health record (EHR) has become a main-stream information technology (IT) development worldwide for the purpose of enhancing healthcare quality. Due to the fact that health records are mainly created and used by physicians, it appears that the advantages of EHR could not be fully taken without their support and participation. The main purposes of this study were to understand the various EHR systems current used by physicians, the latter's cognition and willingness of using portable EHR, and to explore the relevant influential factors of physicians' acceptance to portable EHR. Methods: This study adopted a quantitative cross-sectional approach, and our subjects were physicians from nine medical centers, which participated in Taiwan DOH's ”Building of an Information Exchange Environment for Cross-Hospital Digital Medical Record” project. A Technology Acceptance Model (TAM) was the basic scheme of our research design. A set of structured questionnaire and 5-points Likert Scale were used as our research tool. After a reliability and content validity test, certain numbers of copies of the questionnaire were sent to each of the nine medical centers. After all, 426 copies of the questionnaire were returned and found valid, and the effective response rate was 25.6%. Results: The factors affecting physicians' acceptance to portable EHR were: technical cognition (including perceived usefulness, perceived easiness of use, and familiarity with portable EHR process) (p＜0.001), computer self-efficacy (p=0.038), and some external environmental factors (including adding remarks, electronic signature, time stamp, authorization limits, and access control) (p=0.013). The explanation power of model R^2 was 49.1% (adjusted R^2=0.491). Conclusions: Perceived usefulness, perceived easiness of use, and familiarity with EHR process were found to be the three major factors influencing physicians to accept the portable EHR. Since most of those physicians having bothered to answer the questionnaire were not satisfied with the overall traditional paper medical record environment and also not willing to familiarize themselves with portable EHR process, it appears to be a good timing for the hospital to promote and develop HER system. If the government could offer some incentives like funds or subsidization to encourage hospitals to provide services and educational trainings, it would be very helpful to the research and promotion of HER.
