A study of standardised medical sign language in Thailand links a mobile app workshop with short-term gains in participants’ self-reported health literacy. The research also proposes five policy measures intended to improve healthcare access for people with hearing loss.
The framework combines a vocabulary of medical signs with MU-silentcare, a mobile application, and evidence gathered across seven regions. Its authors describe the barriers as consequences of health-system design, rather than hearing status. The study examines how communication tools, service standards and resource decisions could make rights to equitable care more practical.
The open-access research was published in the International Journal for Equity in Health on 02 November 2026. The source describes the shared paper as peer-reviewed and accepted, while noting that this early version may receive edits before the final Version of Record replaces it.

Standardised medical sign priorities came from participants
Researchers used a sequential explanatory mixed-methods design with three phases. First, semi-structured interviews and focus groups involved 138 purposively sampled stakeholders, including people with lived experience. That phase identified twelve issues across health literacy barriers, healthcare access and service-quality gaps, and systemic policy deficiencies.
In the second phase, 421 people with hearing loss completed a validated needs-assessment questionnaire. The instrument had a Cronbach’s alpha of 0.92 and an Item-Objective Congruence Index of 0.8. Researchers analyzed responses with the modified Priority Needs Index. Participants ranked healthcare access at -0.50 and digital innovation at -0.45 among their highest-priority needs. Urgent-care response times received the highest importance rating, 4.67 out of 5.
Those results center needs reported by people with hearing loss rather than assumptions about what they require. They also give the policy proposals a stated evidentiary path: qualitative accounts identified problems, and the questionnaire measured priorities across a larger clustered sample.
Workshop measured reported changes, not long-term outcomes
The third phase used a 14-day MU-silentcare workshop as a working demonstration of technology integrated into care. Researchers measured outcomes with pre-post paired-samples t-tests involving 453 participants, then validated proposed policies through focus groups with 88 stakeholders.
The study reports statistically significant improvement across all five self-reported health-literacy dimensions. The overall result was t(452) = -30.42, p
These measures capture participants’ reported capability immediately after the workshop. They do not establish lasting gains, clinical outcomes or effects during routine care. The distinction matters because the intervention was a short demonstration, and the source does not report long-term follow-up.
The research sits within broader reporting on healthcare innovation and access gaps and digital infrastructure for care and research. Its focus is the specific evidence and policy proposals described in this study.
Five proposals connect evidence with policy
Convergent findings from the three phases informed five distributive policy proposals: standards for visual health-communication media, mandatory deaf-friendly service points, removal of mobile-device restrictions, cross-sector coordination, and equitable resource allocation. According to the researchers, ministerial regulation under existing law could implement the proposals within one policy cycle without new primary legislation.
The authors frame the measures as a way to direct tools, services and resources toward the points where patients communicate symptoms, understand diagnoses and seek urgent care. Their recommendations therefore address the organization of clinical encounters as well as the sign vocabulary and app.
The policy question is whether the proposed measures move from regulation into routine practice across Thailand’s regions. The study offers short-term, self-reported workshop results and a set of evidence-traceable proposals; implementation and longer-term outcomes remain to be established. Related reporting on healthcare access across policy boundaries examines a different setting, while this research centers communication access for people with hearing loss in Thailand.
