Enhancing Usability of Health Information Technology: Comparative Evaluation of Workflow Support Tools
BACKGROUND
The Breast and Gynecologic System of Excellence (BGSOE) program has developed a workflow support tool using health information technology to assist clinicians, coordinators and stakeholders in identifying, tracking and supporting Veterans with breast and gynecological cancers. This tool was designed and implemented through a novel process that involved clarifying program aims, defining workflows in process delivery diagrams, and identifying data, analytic products, and user needs. To determine the optimal tool for the program, a comparative usability evaluation was conducted, comparing the new workflow support tool with a previous tool that shared identical aims but utilized a different approach.
METHODS
Usability evaluation employed the System Usability Scale (SUS) and measured acceptance using modified items from a validated instrument used in a national survey of electronic health records. Task efficiency was evaluated based on time taken and the number of clicks required to complete tasks.
RESULTS
Eight healthcare professionals with experience in the BGSOE program or similar programs in the VA participated in the usability evaluation. This group comprised physicians (38%), clinical pharmacist (25%), health care coordinators (25%), and registered nurse (12%). The workflow support tool achieved an impressive SUS score of 89.06, with acceptance scores of 93% (positive statements) and 6% (negative statements), outperforming the standard tool, which scored score of 57.5 on the SUS and had acceptance scores of 53% (positive statements) and 50% (negative statements). In the comparative ranking, 100% of the users preferred the workflow support tool, citing its userfriendliness, intuitiveness, and ease of use. On average, users completed all tasks using the workflow support tool in 8 minutes with 31 clicks, while the standard tool required 18 minutes and 124 clicks.
CONCLUSIONS
The adoption of a workflow support tool in the design of health information technology interventions leads to improved usability, efficiency, and adoption. Based on the positive results from the usability evaluation, the BGSOE program has chosen to adopt the workflow support tool as its preferred health information technology solution.
