Abstract:A previous pre-post pilot intervention study using the NASA-TLX, System Usability Scale, and time-motion measures found that after Urgent/Convenient Care clinics (UCC) made the switch from a hybrid paper and electronic health record (H-HER) to a meaningful use EHR system (MU-EHR), physician staff perceived an increase in workload, while nursing staff expressed less perceived changes in workload. Decreased usability ratings that accompanied the introduction of the MU-EHR system suggest that increased workload could be explained by its increased difficulty of use compared to its predecessor, the hybrid system. The National Institute of Standards and Technology (NIST) has issued a document for the Technical Evaluation, Testing, and Validation of the Usability of Electronic Health Records, which includes a comprehensive checklist for Expert Review of EHR, which we condensed and adapted to fit Nielsens 10 Usability Heuristics. We will use this checklist to conduct two tasks: (1) a Heuristic evaluation (HE) of an EHR interface, as it is used to conduct certain tasks by physicians and by nurses; (2) A structured observation of typical UCC clinical tasks as performed by an expert physician and expert nurse user of the vendordesigned EHR system, in order to create a cognitive task analysis of each task. The HE allows us to explore usability issues more directly, while the structured observation helps us quantify the amount of work completed. We hope that together, these two evaluation activities will help us interpret physicians and nurses previous self-reports of usability and workload.
