Alcohol Use Disorder

Alcohol use disorder (AUD) is a chronic health condition characterized by impaired control over alcohol use, continued consumption despite harm, and clinically significant effects on health, functioning, and social wellbeing. Its burden spans prevention, screening, diagnosis, treatment, recovery support, and harm reduction. Effective responses require coordinated public-health, primary-care, specialist, community, and social-service systems.

The field is shifting from episodic treatment toward continuous, person-centered care. Earlier screening in primary care, trauma-informed practice, medications for alcohol dependence, psychosocial therapies, peer recovery support, and attention to housing, mental health, and other social determinants are increasingly treated as complementary elements. Digital access and telehealth can extend support, while stigma reduction remains essential to improving timely engagement and retention.

Artificial intelligence can support AUD services through risk identification, clinical decision support, personalized outreach, appointment and adherence support, and analysis of patient-reported outcomes. Its use must remain clinically governed, transparent, privacy-preserving, and validated across demographic and language groups. Models should supplement-not replace-professional assessment, informed consent, safeguarding, and equitable access to human care.

North America continues to require stronger integration of primary care, behavioral health, emergency services, and recovery support, with emphasis on reducing stigma and treatment gaps. Latin America benefits from community-based models and culturally appropriate prevention while addressing uneven specialist access. Europe combines established public-health infrastructure with national variation in screening and treatment pathways. The Middle East and Africa require locally adapted services, workforce development, and confidential care models. Asia-Pacific spans highly diverse systems, making rural access, culturally responsive outreach, and integration with general health services central priorities.

ASEAN cooperation can support shared prevention approaches, workforce training, and cross-border learning. BRICS members can exchange evidence on affordable treatment, community delivery, and health-system integration. The European Union can strengthen comparability of indicators and coordinated prevention. G7 collaboration can advance research, digital governance, and evidence-based policy. GCC systems can expand culturally appropriate screening and confidential treatment pathways. NATO members can reinforce alcohol-health services for military personnel, veterans, and their families while protecting clinical independence and privacy.

Australia can build on primary-care and community approaches while improving rural continuity. Brazil and Mexico can expand integrated, community-based services and reduce regional access gaps. Canada, the United States, and the United Kingdom can strengthen coordinated care, prevention, and recovery supports across fragmented systems. China and India can broaden screening, specialist capacity, and culturally appropriate community services. France, Germany, Italy, and Spain can improve consistency between primary, specialist, and social care. Japan and South Korea can address stigma, aging populations, and workplace-linked support. Russia requires resilient, confidential, evidence-informed services with attention to continuity and social reintegration.

Industry and health-system leaders should embed validated screening and brief intervention in routine care; expand access to evidence-based psychosocial and pharmacological treatment; connect services with mental-health, primary-care, housing, and social supports; and design recovery pathways around patient goals. They should measure engagement, retention, safety, functioning, and equity rather than relying solely on service volume. Digital and AI tools should undergo bias, security, explainability, and clinical-safety review, with clear escalation to qualified professionals and meaningful patient consent.

This executive summary uses a structured qualitative synthesis of established clinical and public-health concepts relevant to AUD, including prevention, screening, diagnosis, treatment, recovery, harm reduction, service delivery, digital health, and equity. Findings are organized across required regions, multinational groups, and countries to identify common system priorities and contextual differences. No market estimates, market shares, forecasts, or company-specific claims are used. Interpretation should be complemented by current national guidelines, epidemiological surveillance, and local stakeholder consultation.

AUD requires sustained action across the full continuum of care rather than isolated interventions. The strongest direction is toward earlier identification, integrated treatment, recovery-oriented support, responsible digital innovation, and policies that address stigma and social determinants. Leaders who align clinical quality, public-health prevention, data protection, and equity can make services more accessible, responsive, and effective across diverse populations.
