Usability testing is often performed on health information systems in hospital settings. Task-completion time is a frequently used measure of efficiency and a marker of successful systems. This paper presents a systematic review of the literature to determine if usability testing during the implementation of health information systems in hospitals is associated with reductions in the time necessary to complete tasks. Multiple databases were searched for combinations of search term variants. Search results were reviewed by two independent reviewers. Three studies met inclusion criteria. Although the studies report reductions in task-completion time on systems that have been modified after usability testing, rigorous original research that supports this theory is sparse.
