Applying Electronic Medical Records in health care: Physicians’ perspective

M. Abdekhoda, M. Ahmadi,  A. Dehnad, A. Noruzi, M. Gohari

Summary

Background: In order to fulfill comprehensive interoperability and recognize the electronic medical records (EMRs’) benefits, physicians’ attitudes toward using and applying EMR must be recognized.

Objectives: The purpose of this study was to present an integrated model of applying EMRs by physicians.

Methods: This was a cross sectional study in which a sample of 330 physicians working in hospitals affiliated to the Tehran University of medical sciences (TUMS) was selected. Physicians’ attitudes toward using and accepting EMR in health care have been analyzed by an integrated model of two classical theories i.e. technology acceptance model (TAM) and diffusion of innovation (DOI). The model was tested using an empirical survey. The final model was tested by structural equation modeling (SEM) and represented by Analysis of Moment Structures (AMOS).

Results: The results suggest that the hybrid model explains about 43 percent of the variance of using and accepting of EMRs (R2=0.43). The findings also evidenced that Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Relative Advantage, Compatibility, Complicatedness and Trainability have direct and significant effect on physicians’ attitudes toward using and accepting EMRs. But concerning observeability, significant path coefficient was not reported.

Conclusions: The integrated model supplies purposeful intuition for elucidates and anticipates of physicians’ behaviors in EMRs adoption. The study identified six relevant factors that affect using and applying EMRs that should be subsequently the major concern of health organizations and health policy makers.

The effects of organizational contextual factors on physicians’ attitude toward adoption of Electronic Medical Records

Mohammadhiwa Abdekhoda, Maryam Ahmadi, Mahmodreza Gohari, Alireza Noruzi

Abstract

Introduction: Physicians’ adoption seems to be a significant issue when comprehensive implementation of Electronic Medical Records (EMR) is considered. This study was conducted to determine the organizational contextual factors affecting physicians’ adoption of EMR.

Methods: This was a descriptive-analytical study in which a sample of 330 physicians working in hospitals affiliated to Tehran University of Medical Sciences was selected. Physicians’ attitudes toward EMRs’ adoption have been assessed by a conceptual path model of Technology Acceptance model (TAM) and organizational context variables. Collected data were analyzed by SPSS16 using regression analysis. The final model was tested by structural equation modeling (SEM) and represented by SPSS–AMOS, structural equation modeling software.

Results: The results suggest that modified proposed conceptual path model explains about 56% of the variance of EMRs’ adoption. The findings also evidenced that perceived usefulness (PU), perceived ease of use (PEOU), management support; physicians’ involvement, physicians’ autonomy, and the doctor–patient relationship have direct and significant effect on physicians’ attitudes toward EMRs’ adoption. However, training showed to have no significant effect on PU and PEOU.

Conclusion: The present study acknowledged that considerable part of physicians’ attitude toward EMRs’ adoption is controlled by organizational contextual factors. These factors should be subsequently the major concern of health organizations and health policy makers.
