NIST releases technical guidance for evaluating EHRs.
Press Release Summary:
Mar 22, 2012 - NIST has outlined formal procedures for evaluating usability of Electronic Health Records systems. Proposed usability protocol encourages user-centered approach to development of EHR systems. It provides methods to measure and address critical errors in user performance before those systems are deployed in medical setting. Three-step process consists of an analysis of how application functions, expert review, and validation testing of user interface to make sure it works as intended.

NIST Releases Technical Guidance for Evaluating Electronic Health Records
Press release date: Mar 20, 2012
The proposed usability protocol encourages a user-centered approach to the development of EHR systems. It provides methods to measure and address critical errors in user performance before those systems are deployed in a medical setting.
"This guidance can be a useful tool for EHR developers to demonstrate that their systems don't lead to use errors or user errors," said NIST researcher Matt Quinn. "It will provide a way for developers and evaluators to objectively assess how easy their EHR systems are to learn and operate, while maximizing efficiency."
The protocol is a three-step process consisting of an analysis of how the application functions, expert review, and validation testing of the user interface to make sure it works as intended.
The protocol includes general steps and guidance for evaluating an EHR user interface from a clinical perspective-does it contain, collect and display the information it needs to-and human factors perspectives-can the user understand it and easily find needed information. The interface is then tested by representative user groups performing realistic tasks.
"We hope this encourages system developers to apply human factors best practices and incorporate user-centered design processes," said Quinn. "These practices and processes have proven records in industries such as aviation, military systems, transportation, nuclear power, and others where safety is a concern."
The EHR Usability Evaluation Protocol (EUP), Technical Evaluation, Testing and Validation of the Usability of Electronic Health Records (NIST Interagency Report 7804), is available at www.nist.gov/healthcare/usability/index.cfm. A draft version of the document was released for public comment in September 2011. The current version incorporates feedback received.
