Studying the human-computer-terminology interface.
Objective: To explore the use of an observational, cognitive-based approach for differentiating between successful, suboptimal, and failed entry of coded data by clinicians in actual practice, and to detect whether causes for unsuccessful attempts to capture true intended meaning were due to termino...

Response time averaged 0.74 sec, and total event time averaged 40.4 sec. Of an additional 209 tasks related to drug dose and frequency terms, 94 percent were successful, 0.5 percent were suboptimal, and 6 percent failed, for an overall success rate of 82 percent.Conclusions: Data entry by clinicians using the outpatient system and the MED was generally successful and efficient. The cognitive-based observational approach permitted detection of false-positive (suboptimal) and false-negative (failed due to user interface) data entry. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
