As the healthcare industry transitions from paper to electronic medical records (EMRs), medical informatics researchers face the task of ensuring that the electronic presentation of the information remains usable and effective while capitalizing on the ability of EMRs to tailor information to different users.

As the healthcare industry transitions from paper to electronic medical records (EMRs), medical informatics researchers face the task of ensuring that the electronic presentation of the information remains usable and effective while capitalizing on the ability of EMRs to tailor information to different users. In our research, we focus on utilizing formal cognitive science methodology to guide the conversion of paper-based narrative discharge summaries to a more dynamic, structured electronic version. In this paper, we present the results of a cognitive analytic study (1) that determines a ‘core’ component in medical narratives and (2) that compares the use of structured and narrative texts by physicians with varying expertise. Specifically, we studied six psychiatrists at three levels of expertise— experts, intermediates, and novices. The subjects were given two clinical case scenarios with discharge summaries and asked to verbalize their thoughts as they read through the summaries. The interview transcripts were analyzed for recalls and inferences generated in the verbalization. Based on experts’ verbalizations, the discharge summaries were organized into a more structured form and used in the interview of other subjects. Novice-level subjects had more recall with the structured than with the narrative format. More errors were also made in recall with the narrative than with the structured text. We discuss how these results are valuable in designing an EMR interface to reduce errors and to support users of different expertise. Show less

Electronic medical record (EMR) systems have important potential advantages over traditional paper-based systems, but they require that physicians assume responsibility for data entry. However, little is known about the quality of physician data entry in electronic systems. This study describes a system for comparing the speed, accuracy, and completeness of examination data entry using electronic and paper methods. Data will be shown to demonstrate that this may be a simple, reproducible, and… Show more

However, little is known about the quality of physician data entry in electronic systems. This study describes a system for comparing the speed, accuracy, and completeness of examination data entry using electronic and paper methods. Data will be shown to demonstrate that this may be a simple, reproducible, and useful technique. Show less
