Abstract
Doctors' acceptance study can provide significant feedbacks to all stakeholders
regarding the issues in the EMR implementations. The feedbacks are essential
to improve quality and efficiency, to prevent medical errors, and to enhance
consumers' confidence in the Malaysian healthcare system. Therefore, the main
objective of this research is to develop doctors' acceptance model of EMR in
Technical, Social, and Behavioral Perspectives. This model adapted
Technology Acceptance Model (TAM) as a basic theory. The study involved
survey method. The site studies are chosen from two pioneer hospitals that use
the EMR, Selayang and Putrajaya hospitals. These two case studies can
provide a reasonable amount of variance and generalization. Self-administered
questionnaires were used in the survey. Findings from survey resulted in the
development of the Multiple Perspective Technology Acceptance Model (MPTAM)
for EMR. MP-TAM consists of three perspectives: technical, social and
behavioral. Technical Perspective that is composed of three factors: System
Capabilities, Information Quality and User Interface were shown to have
positive significant relationship with Perceived Usefulness (PU) and Perceive
Ease of Use (PEOU), the two factors in Social Perspectives. PU and PEOU
were also shown to have the positive significant relationships with User
Satisfaction, the factor that was included in the Behavioral Perspective. This
study has contributed new knowledge to Health Informatics (HI). The MP-TAM
can provide evidences related to the acceptance of EMR by doctors. In addition,
MP-TAM also can justify the strengths and weaknesses of the observed IT
application in terms of System Capabilities (Cap), Information Quality (IQ), and
User Interface (UI) of the system. Therefore, EMR developer can enhance the
weaknesses of the EMR system. The most important contribution of this
research is towards the extended TAM model composed of technical, social,
and behavioral perspectives. Therefore, these findings enhanced the theoretical
knowledge especially related to the TAM model that was applied in Health
Informatics Domain. This study also extended the classical TAM model, which
originally consisted of PU and PEOU from Social Perspective, by introducing
the Cap, Ul, and IQ from Technical Perspective and US from Behavioral
Perspective. For the future, the study can be repeated with other group of users
in the same setting to identify the overall user acceptance of EMR. The model
can be tested in the non-mandatory health organization such as in private
hospitals by broadening the behavioral perspective to include Intention to Use,
Attitude, and Usage factors. MP-TAM can also be used to study user
acceptance in other IT applications, so that the model can be generalized in IT
domain.
