Abstract
Heuristic evaluation is a type of study that is useful for uncovering usability issues in a human-computer interface such as the electronic medical record (EMR). Findings can be very useful in overcoming usability problems to better realize the benefits of the EMR. Correction of the usability violations will improve the efficiency and effectiveness of EMRs. The authors discuss their use of heuristic evaluation to assess usability issues found in their nursing electronic documentation system.
