Previous research has identified gender and racial disparities in the burden of diagnostic errors. In this study, researchers conducted a series of human-centered design workshops with a diverse set of stakeholders who generated a set of design challenges, principles, and solutions for addressing diagnostic disparities, improving healthcare quality, and promoting equity and inclusion of marginalized patients. Participants also identified two prototypes for the solutions – a visit preparation guide to teach patients how to advocate for themselves and a tool for identifying patients who may be at increased risk for experiencing a diagnostic error.
