Overview

Usability study demonstrates reduced application errors and completion times with a digital tool for HIV pre-exposure prophylaxis coverage, highlighting the value of administrative aids.

Key Points

To develop and evaluate the Pre-Exposure Prophylaxis Access Navigator, a digital tool designed to help individuals independently complete public drug program financial assistance applications.
Conducted a two-phase usability study guided by the Toronto Translational Framework using standardized applicant profile scenarios.
Evaluated native drug program applications in Baseline Testing (n=10) and iteratively assessed Alpha, Beta, and Gamma digital prototypes (n=15).
Assessed quantitative critical-error rates, completion duration, and System Usability Scale ratings alongside qualitative think-aloud and interview data.
Baseline native application testing resulted in a 100% critical-error rate and longer overall completion times.
The final Gamma prototype iteration achieved a 0% critical-error rate and reduced total completion time by 19.8%.
Usability scores improved substantially across iterations, with participants reporting higher confidence, clarity, and ease of navigation.
