NIST has launched a Wiki to support collaboration among all stakeholders in developing tools for measuring and evaluating the usability of Health IT systems.

The NIST Health IT (HIT) Usability initiative is focused on providing technical guidance in developing standards for assessing and improving the usability of electronic health records (EHRs) and related technology. This work is being conducted in collaboration with the Office of the National Coordinator for Health Information Technology (ONC) and the Agency for Healthcare Research and Quality (AHRQ). The initiative will examine the human factors critical to designing usable EHRs, and will incorporate the findings into recommended usability engineering practices for the HIT industry. The ultimate objective of this initiative is to create a detailed specification of an objective, repeatable procedure for measuring and evaluating the usability of HIT systems.
