The Self-management TO Prevent (STOP) Stroke Tool is a clinical decision support tool that prompts providers on clinical practice guidelines for secondary stroke prevention while simultaneously providing access to patient education materials and instruction for patient self-management. We designed the initial prototype as a Reminder Dialogs (RD) template in CPRS. Testing of the template-based tool revealed usability barriers related to RD template applications.
For this project, we sought to identify redesign strategies to modify the template-based tool to produce a web-based prototype, and to complete usability testing of the web-based prototype among providers in a simulated clinic visit.
A pre-experimental design was applied using descriptive and qualitative methods. Members of SQUINT - the Stroke Quality Improvement Network (N=12) viewed a video of the proposed design for the web-based prototype. Implementation barriers/facilitators were elicited using an electronic evaluation form. A Think-Aloud protocol was employed to test the usability of the web-based prototype. A convenience sample of stroke-care providers (N=10) from two VAMC facilities completed the Think-Aloud protocol. Participants' responses were grouped and tabulated into content categories to identify perceived barriers/facilitators for implementation in clinical practice and for provider-to-patient communication. Audio-tapes from the Think-Aloud protocol were transcribed and investigator field notes were incorporated. A directed approach for content analysis was used to code participants' dialogue into word and word phrases that were indicative of either barriers or facilitators to accessibility, usability or usefulness.
SQUINT members identified the systematic format, comprehensive information, and automated features of the web-based design as facilitators to implementing the STOP Stroke Tool in practice. Barriers revolved around time to complete the tool, lack of interoperability with CPRS, and access to a printer during the encounter. Facilitation of provider-to-patient communication was identified as one key design features of the web-based interface. Barriers were possible distractions while using a computer and interacting with a patient. Usability testing indicated that access to comprehensive information was the primary accessibility facilitator. Usability facilitators were the tool's automated features and systematic process. The need for training, time to complete the tool, and computer centric care were identified as usability barriers. Usefulness facilitators of patient accountability, reminder for best practice, goal focused care, and communication/counseling indicate that the STOP Stroke Tool supports the paradigm of patient-centered care. Participants identified unclear target end-user and limited options for care other than stroke risk factor management as key usefulness barriers.
This project contributes new knowledge on use of health information technology to implement and monitor quality care within the VHA. Continued research will be directed toward testing provider/patient collaborative management of stroke risk factors while using the STOP Stroke Tool as compared to usual care practices.
