Training medical providers to serve diverse deaf patients: Age-based intervention effects in a randomized trial.

BACKGROUND

Deaf American Sign Language users are severely underserved in the U.S. healthcare system. To address longstanding inaccessibility and mistrust, our Deaf community-led team produced a film to train providers to better serve Deaf patients - Vital Signs.

OBJECTIVE

We conducted a two-arm randomized controlled trial to evaluate preliminary efficacy of Vital Signs among healthcare providers and health professions students.

METHODS

Participants were randomly assigned to review Vital Signs or intervention as usual - standard written guidance about working with Deaf patients. Intervention completers were invited to participate in a simulation with a Deaf standardized patient. Three Deaf team members were trained to review simulation recordings and complete validated patient self-report measures of provider behavior: Healthcare Provider Cultural Competency; Ask, Understand, and Remember Assessment; and Wake Forest Physician Trust Scale.

RESULTS

Of 208 enrolled participants, 52 completed all study components and were included in final analyses. A clear pattern of results emerged - participant age influenced learning and behavior change in response to different training strategies. Participants aged 33+ who viewed Vital Signs scored higher on content knowledge compared to same-aged peers who reviewed training as usual, but worse across measures of cultural competency, communication skill, and trust-building. An opposite pattern emerged for participants younger than 33 years - those who watched Vital Signs exhibited greater cultural competence, communication skill, and trust-building abilities than same-aged peers who reviewed standard written guidance.

CONCLUSION

Future steps include an implementation trial of various Vital Signs training configurations, evaluating strategies for training health professions students versus experienced providers.
