The success of health information technology implementations is often tied to the impact the technical system will have on the work of the clinicians using them. Considering the role of nurses in healthcare, it is shocking that there is a lack of evaluations of nursing information systems in the literature. Here we report on how a human factors approach can be used to address barriers and facilitators to use of the nursing information system (NIS). Human factors engineering (HFE) approaches provide the theoretical and methodological underpinning to address these socio-technical issues. ⋯ This study examined the use of an NIS to standardize care and documentation in nursing. It used scenario-based usability testing, applying the "think-aloud" protocol technique to assess the use of the NIS in documenting patient care. This method of usability evaluation exposed an understanding of how nurses use the NIS and their perspective on the system. We hypothesize that this method will offer key insights into how the usability of the NIS not only impacts use but also informs redesign opportunities. In addition, this is one of the few rigorous studies of NIS and provides direction and recommendations for informaticians, developers and nurse decision makers.
