127 A formative usability evaluation of a community pharmacist-facing health information exchange (HIE) interface

Abstract

OBJECTIVES/GOALS: To evaluate the usability of a HIE interface design among community pharmacists and technicians to identify opportunities for design improvements METHODS/STUDY POPULATION: Pharmacists and pharmacy technicians employed at Indiana community pharmacies participated in formative usability testing, via a Rapid Usability Evaluation (RUE), with an interactive, PDF prototype of the HIE interface. Participants were video-recorded to capture first impressions on the usability of the HIE prototype via the think aloud technique. Each participant had up to 1 hour to complete 4 clinical scenarios. Afterwards, participants completed the System Usability Scale (SUS; scale 0–100, with 100 being the best) to rate their satisfaction with the HIE prototype. RESULTS/ANTICIPATED RESULTS: Across 3 community pharmacies, 16 individuals participated in usability testing: 8 pharmacists and 8 technicians. The average SUS score for the HIE interface across participants from all sites was 70. Pharmacists on average scored the interface higher than technicians, 74 vs. 65, respectively. Initial findings from one pharmacy revealed that both pharmacists and technicians expressed a desire for improved efficiency (i.e. fewer clicks ) to access HIE data, alternative placement of HIE links within existing systems, and improved navigation to exit HIE links. DISCUSSION/SIGNIFICANCE: Initial results reveal opportunities to improve the HIE interface usability. Findings will inform design improvements to the interface and the creation of a toolkit to support the sustainable and scalable participation in HIE by community pharmacies.
