Providing language access in healthcare

Language access enables patients to explain symptoms, understand care and participate in decisions through a shared language or qualified interpreting and translation. Healthcare organisations need services, trained people, reliable processes and technology that reach patients throughout their care, including when language needs are urgent or unanticipated.

People and care affected

Language barriers affect migrants, people with hearing impairments, ethnic minorities, people unable to read, medical tourists and tourists who become ill. ¹ Local needs vary: rural hospitals may serve migrant agricultural workers, while urban safety-net systems and international centres serve immigrants with differing legal status, refugees, new arrivals, tourists and international patients. ² Figures reported in 2016 included nearly 863,000 UK residents not proficient in English and 50,000 deaf residents, and 25.3 million US residents with limited English proficiency and 30 million deaf or hearing-impaired residents. ³

Barriers interfere with booking appointments, explaining symptoms and history, understanding diagnoses, reading documents and giving informed consent. ³ They increase risks of medical errors, emergency visits and unnecessary laboratory tests, reduce adherence to medication instructions and increase dissatisfaction. ³ Diagnostic delays, misunderstood advice and poorer outcomes also affect patients with language barriers. ² Professional language services help patients obtain appropriate care and help clinicians meet ethical and legal responsibilities. ¹

Inadequate access reduces adherence and can increase mortality. ⁴ In one US hospital case, a breast-cancer patient achieved cancer-free status but received no follow-up and returned two years later with untreatable metastatic disease; she had never understood that treatment was planned for five years. ⁵ Poor communication also reduces the likelihood that dissatisfied patients will return or recommend a facility and contributes to clinicians' moral distress and burnout. ⁶ A Portuguese-language hospital-survey response described liking a doctor who believed he spoke Portuguese, while only sometimes understanding him. ⁵ Language barriers are associated with patient harm, longer stays, readmissions, compromised wellbeing and higher costs. ⁷

An observational US paediatric intensive-care study found mortality among Latino children 3.7 times that of White and African American children after adjustment for illness severity. ⁴ A multilevel intervention combined clinician cultural-sensitivity training, more bilingual staff, expanded trained-interpreter availability in emergency and intensive care, multilingual consent and education materials, and outreach to Latino communities. ^{4, 5} Over the following three years, Latino children's mortality fell to comparable levels; the hospital addressed multiple factors rather than outsourcing language services as a single solution. ⁵

In another case, an American Sign Language user became distressed during an eye injection without an interpreter. ⁸ For a repeat procedure, the clinician planned sedation, but an interpreter recommended explaining risks and benefits; the patient then consented and cooperated without sedation, saving anaesthesia, staffing, operating-room and hospital-stay costs. ⁸

Accessible native-language information supports adherence, trust, patient participation and healthcare efficiency; reliance on family members, fragmented communication or generic online tools can introduce errors and delays. ^{9, 10} Illustrative risks include inability to communicate a child's symptoms, history and allergies in an emergency; exclusion from a trial whose consent, instructions and follow-up assessments are available only in the local language; and harmful public-crisis guidance translated without human oversight. ^{9, 10}

Provision and barriers to commissioning

In 2012, UK NHS interpreting and translation spending was £23.3 million, including £3 million on translation. ¹¹ Annual hospital spending reported in 2016 ranged from £60,000 to £1 million. ¹¹ Swedish national-health-service investment was reported as €45 million, then about £31 million. ¹¹ Yet reports summarised in 2016 found professional interpreters used in only 30% of California hospitals and six qualified interpreters across 1,008 surveyed British consultations. ¹¹ A British report found 40% of hospitals employed no translators and 8% translated no documents; translations covered only five to twenty-five of roughly 100 spoken languages, with similar US findings and frequent failures to translate key documents such as consent forms. ¹¹ Need was increasing globally while services remained underused and faced budget cuts. ¹¹

Four reported barriers help explain underuse: ^{12, 13, 14, 15}

1. Finance and awareness. Upfront fees deter budget-constrained hospitals, alongside limited clinician awareness. Alternatives have included restricting documents or languages, translating only on request, using oral communication to avoid administrative or literacy issues, and recommendations to use bilingual staff or free website-translation software.
2. Ad hoc interpreting. Figures reported in 2016 put reliance on family members and bilingual staff at 70% of UK consultations needing translation and 80% in Australia. Practitioners viewed it as easy, free, time-saving and sometimes more trusted in small or religious communities. Lip-reading, gestures and notes were also assumed convenient, despite differences in literacy, lip-reading ability and gestures' cultural meanings.
3. Equipment. Rooms may lack telephone or video devices; even where available, some doctors considered telephone interpreting awkward and complex.
4. Professional attitudes. Most doctors interviewed for a BBC report believed patients should arrange and pay for interpreters, migrants should learn English, and public funds should prioritise staff, supplies and medicines. These views reflected misunderstanding of professional language services' importance.

^{12, 13, 14, 15}

Language needs also go unreported when patients fear disclosure or institutions ask inadequate questions, leaving investment based on incomplete data and encouraging unsafe shortcuts. ¹⁶

Risks of untrained substitutes

Qualified interpreters are independent, impartial, medically knowledgeable and bound by confidentiality; untrained substitutes may misuse information in insurance, legal proceedings or wills. ¹⁷ Ad hoc interpreters may alter, add or omit information for personal or cultural reasons, particularly around HIV, infertility, child or sexual abuse, domestic violence or abortion; family members may be distressed or uncomfortable translating sensitive subjects, especially to children. ¹⁷ Terminology errors can be serious or fatal: an interpreter may fail to explain rectal bleeding and treatment, confuse “humoral” with “humeral”, mix words across languages or miss specialty-specific meanings. ¹⁷ A 2025 account linked use of family, friends and unvetted online tools in UK clinical settings with preventable deaths and described inconsistent NHS language-service management. ²

Rights, consent and liability

WHO's 1946 constitution recognised the highest attainable standard of health as a fundamental right without distinction by race, religion, political belief or economic or social condition. ¹⁸ The right includes equitable health information, participation in health decisions and freedom from nonconsensual treatment, experiments and forced sterilisation. ¹⁹ In 2024, only 38% of states were reported to constitutionally guarantee healthcare services and 14% public health; many limited noncitizen obligations to variably defined essential or emergency care, leaving interpretation to institutions or practitioners. ²⁰

Professional conduct requires sensitivity to cultural, social, ethnic and disability differences. ¹⁷ Withholding translated consent or discharge documents from patients with limited English proficiency was described in 2016 as violating equal treatment, care access and consent protections in the Convention on Human Rights and Biomedicine. ¹⁷ Missing translated preventive information can also put patients at risk. ¹⁷

In 2024, the US had no formally codified right to health, but federal language-access rights were implemented and enforced unevenly across states. ²⁰ Florida's patient bill of rights provided an interpreter if one was readily available at the facility, and Florida was then the only state requiring hospitals to ask citizenship status. ²⁰ Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act were cited in 2025 as protecting meaningful language access, with inconsistent implementation; replacement of Executive Order 13166 by 14224 raised concerns about language equity, health outcomes and institutional liability. ^{2, 17}

UK legal accounts differ. ^{17, 2} In 2016, language access was described as lacking broad legislation, while practitioners could be negligent for failing to obtain consent despite knowing an interpreter or translator was needed. ¹⁷ Practitioners were also responsible for ensuring understanding of interpreted or translated information. ¹⁷ Reported cases included sterilisation without a low-English-proficiency patient's consent, a translated consent form given to a patient unable to read it even in her native language, and delayed diagnosis of a child's Kawasaki disease when the family had not received professional interpreting, resulting in damages. ¹⁷ The Equality Act 2010 prohibited discrimination including disability discrimination, and deaf patients had successfully sued facilities for failing to provide professional sign-language services. ¹⁷ The 2025 account interpreted that Act as guaranteeing interpreters to non-English speakers using public services. ²

EU healthcare directives protected access across borders and against nationality discrimination but left language rules to member states in 2024. ²⁰ National redress was available on both sides of the Atlantic, with practical protections depending on local policies. ²⁰

Language and health equity

Language has been proposed both as a social determinant of health and as an independent determinant, with limited majority-language proficiency an unchosen disadvantage requiring institutional and individual action. ²¹ A December 2019 applied-linguistics brief called language a significant but underexplored determinant in underserved language communities and identified a role for applied linguists in reducing disparities. ²¹ Regardless of classification, language barriers compromise consent and autonomy, reduce satisfaction and increase distress, so health equity requires addressing them from the start of care. ²¹

Fear and avoidance related to crises, inequities, immigration enforcement or political conditions can delay care, reduce quality and preventive opportunities and increase costs; COVID-19 screening declines were followed by more advanced disease and preventable complications. ² One cancer patient's health declined under emotional distress after immigration authorities detained her husband, her caregiver and informal interpreter; advice to reduce stress lacked meaning without language and support structures. ²²

Language Justice Framework

Language concordance means patient and provider share a language; patients receive more information and questions, helping earlier accurate diagnosis, while US clinicians report less malpractice fear and greater satisfaction. ²³ Qualified interpreters and translators are the next strategy when concordance is unavailable. ²³ A culture of language justice needs infrastructure, sustained leadership commitment, consistent communication and education, policy and enforcement. ⁷

The proposed Language Justice Framework supports building or improving a programme, grounded in health equity and language access as human rights and the principle of doing no harm. ^{24, 5, 25, 26} Its four pillars are: ²⁷

1. Language services: oral interpreting in person, by video and telephone; qualified and unit-based interpreter staff; translated business-critical communications, vital documents, patient rights, health-app messages and wayfinding; alternative media; and qualified bilingual clinical and nonclinical staff.
2. People: a language-services standards council; professional certification and recognition; career advancement rewarding specialisation, education and contributions; language professionals collaborating with physicians in research and publication; internal and external stakeholder engagement; staff onboarding; and structured in-service training.
3. Processes: assessment of language minorities, frequency and contact points; service policies and procedures; annual goals aligned with health-system goals; internal and external communication of services; data-driven decisions and continuous improvement; easy interpreter and translation requests and dispatch; and bilingual-speaker competency evaluation.
4. Technology: integrated telephone, video and telehealth supporting staff and vendor partners; multilingual education libraries and translation management; electronic records documenting patient and caregiver preferences, oral and written care languages, communication needs and assistive devices; request and dispatch systems; multilingual websites, apps and appointment management; and institutional interpreter communication devices.

²⁷

Institutions should maintain qualified interpreters, nationally certified where applicable, for major minority languages, supplemented by vendors and high-quality backup contracts for urgent or unexpected needs. ²⁴ Assigning interpreters to emergency, intensive-care, surgical and birth units can mitigate time pressures; video devices and internal call centres can support on-demand access. ²⁴ Needs assessment should identify vital documents such as history forms, consent, after-visit summaries, instructions, questionnaires and service leaflets; audio, video, social media and apps can serve those unable to read, speaking languages without written forms or preferring other formats. ²⁴

Interpreters should be valued as team members and cultural consultants, with progression through certification, advanced degrees and contributions to improvement, education and communities. ^{28, 26} Intercultural education ideally starts in medical school; providers, faculty and language professionals can share governance, research and learning, with interpreter scientists advancing practice and literature. ²⁶

Assessment should establish how many languages need service, where and how often people contact the organisation, and right-size all four pillars from reception to operating theatre. ²⁹ Clear signage and instructions should tell patients and visitors that assistance is free. ²⁹ Bilingual clinicians require objective competency verification, and staffing may roughly mirror community language groups; recruiting locally can build trust. ²⁹

Electronic records should capture patient and caregiver language preferences and interpreter needs. ³⁰ Electronic-record integration should make requests and dispatch intuitive, track use and common information, verify compliance and support research and resource advocacy. ³⁰ Metrics can identify successful initiatives and opportunities for improvement. ³⁰ The framework is aspirational and does not promise a perfect system. ³¹

Institutional measures and investment

Recommended measures set out in 2016 were: ³²

• Provide more hospital workshops on ethics and use of language services.
• Translate important documents accurately, including consent, discharge forms and psychometric tests, appointing an interpreter when a patient cannot read or understand them.
• Make translations culturally sensitive, accessible and plain-language.
• Supplement text with pictures and short written or signed dialogues, or combine voice-over, subtitles, signing and pictures in prevention campaigns.
• Simplify interpreter booking, especially in emergencies, using bilingual staff or family only as a last resort when the language is otherwise unavailable.
• Invest in technology and equipped rooms, including operating rooms.
• Consider on-site interpreters for commonly encountered languages.

Qualified translators help produce linguistically accurate, culturally appropriate and patient-friendly information. ³³ Language services improve satisfaction and adherence to medicines and appointments, reduce unnecessary tests and misdiagnosis and can avoid language-related litigation costs. ³² Poor communication increases readmissions, malpractice risk and adverse outcomes, making effective access a financial as well as ethical concern in value-based care. ^{22, 34}

Technology governance and collaborative design

Language access should be treated as healthcare infrastructure, with systems designed together by language practitioners, patients and care teams. ^{35, 36} Programmes should be built locally in institutions and communities. ³⁶ Participatory action research offers a method by centring those most affected in technology design and implementation. ¹⁶ Oversight should ensure compliance, privacy and cultural relevance, with real-world joint testing by patients, interpreters, clinicians and technologists and healthcare-specific, multilingual safety training for models. ¹⁶

Layered access should combine vetted interpreter lines, multipurpose video units supporting several vendors and languages, in-person interpreters for sensitive conversations, and collaboratively developed AI-assisted translation workflows. ²² Every touchpoint should be linguistically appropriate, including apps, chat and asynchronous communication alongside interpreters and documents. ²² Human interpreters also act as cultural brokers and ethical guides, and obligations to patients persist through technological or regulatory change. ^{22, 37}
