Interventions aimed at improving healthcare and health education equity for adult d/Deaf patients: a systematic review

BACKGROUND: d/Deaf people suffer from inequitable access to healthcare and health information. This results in worse health literacy and poorer mental and physical health compared to hearing populations. Various interventions aimed at improving health equity for d/Deaf people have been documented but not systematically analyzed. The purpose of this systematic review is to obtain a global overview of what we know about interventions aimed at improving health equity for d/Deaf people. METHODS: Medline Ovid SP, Embase, CINAHL EBSCO, PsycINFO Ovid SP, Central—Cochrane Library Wiley and Web of Science were searched for relevant studies on access to healthcare and health-related interventions for d/Deaf people following the PRISMA-equity guidelines. We focused on interventions aimed at achieving equitable care and equitable access to health information for d/Deaf people. RESULTS: Forty-six studies were identified and analyzed. Seven categories of interventions facing healthcare or health education inequities emerged: use of Sign Language (1), translation, validation and identification of clinical tools and scales (2), healthcare provider training program (3), development of adapted healthcare facilities (4), online interventions (5), education programs (6) and videos (7). Despite some methodological limitations or lack of data, these interventions seem relevant to improve equity of care and health education for d/Deaf people. CONCLUSION: Interventions that promote healthcare equity, health education amongst d/Deaf patients and healthcare provider awareness of communication barriers and cultural sensitivity show promise in achieving more equitable care for d/Deaf patients. Meaningful engagement of d/Deaf individuals in the conceptualization, implementation and evaluation of health-related interventions is imperative.
