Usability is "the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use" [ISO9241]. Usability represents an important yet often overlooked factor impacting the adoption and meaningful use of electronic health record (EHR) systems. Without usable systems, doctors, medical technicians, nurses, administrative staff, consumers, and other users cannot gain the potential benefits of features and functions of EHR systems.

The Health Information Technology for Economic and Clinical Health (HITECH) Act provides financial incentives and other support to drive the adoption and meaningful use of EHRs. A recent report funded by the Agency for Healthcare Research and Quality (AHRQ), however, identified key shortcomings among certified EHR vendors in the processes, practices and use of standards and best practices with regard to usability and human factors. Efficient and effective use of EHRs is essential as these systems increasingly become a central tool for patient care.
