Studying the impact of interoperable electronic health records on workflow in ambulatory care

• Interoperable EHRs can eliminate, add, or change steps in work processes.
• Implementing EHRs will not necessarily make offices “paperless.”
• Some forms of EHR interoperability may lead to inefficiencies.
• Users are aware of the benefits of, and have positive attitudes towards, EHRs.
• Design choices can have significant impacts on efficiency/quality benefits.

Many of the proposed benefits of health information systems, particularly those regarding efficiency, are assumed to be caused by changes in clinical provider and staff workflow. Assessing the extent to which electronic health records (EHRs) are having the expected effects and identifying barriers to anticipated improvements requires a detailed understanding of how such systems affect day-to-day work activities. This study utilized interviews and observations to develop prototypical workflow models of day-to-day activities in ambulatory practices, allowing activity changes due to the implementation of EHRs with varying levels of interoperability to be identified. Primary and specialty care practices from a multi-county region were sampled. Results showed that EHRs did not consistently improve efficiency, but variously reduced, added, or simply changed work tasks. The impact depended on the work process, level of interoperability, and type of provider involved, as well as aspects of the user interface design. Additionally, implementing EHR systems did not eliminate the use of paper from work processes. Implications for successful implementation and design of EHR systems are provided.Relevance to industryEffectively designing and implementing health IT systems in clinical settings requires an understanding of how the IT system will impact, and be integrated with, existing work activities, and how these impacts may depend on the level of interoperability achieved by the IT system.
