Electronic health record acceptance by physicians: testing an integrated theoretical model.

Area of Science:

• Health Informatics
• Medical Technology Adoption
• Physician Behavior

Background:

• Electronic Health Records (EHR) implementation faces challenges due to limited physician acceptance.
• Understanding physician perspectives is vital for successful EHR adoption strategies.

Purpose of the Study:

• To identify key determinants influencing physician acceptance of EHR systems.
• To analyze factors affecting the intention to use EHR among Quebec general practitioners and specialists.

Main Methods:

• An electronic questionnaire was distributed to physicians in Quebec.
• Four theoretical models (TAM, Extended TAM, Psychosocial, Integrated) were tested using path analysis and regression.
• Sociodemographic characteristics' modifying effects were assessed via multi-group analysis.

Main Results:

• 157 questionnaires were returned; models explained 44-55% of variance in EHR intention.
• The Integrated model identified perceived ease of use, professional/social norms, and demonstrability as strongest predictors.
• Age, gender, experience, and specialty influenced the relationship between determinants and intention.

Conclusions:

• An integrated model effectively identifies factors motivating physician EHR adoption.
• Physicians are more likely to accept EHRs perceived as easy to use, socially supported, and demonstrating tangible benefits.
• EHR implementation strategies should consider physician demographics and experience.
