ATIH

What ATIH does

ATIH (Agence technique de l'information sur l'hospitalisation) is a French state public establishment (établissement public d'Etat) operating under the Ministry of Health as the country's designated national technical agency for hospital and medico-social information. Founded in 2000 and headquartered in Lyon with a Paris office, ATIH operates under statutory mandate to collect, code, analyze, and disseminate standardized medical and administrative data from all French healthcare establishments across four sectors: medicine/surgery/obstetrics (MCO), follow-up and rehabilitation care (SMR), psychiatry (PSY), and home hospitalization (HAD). The agency also covers medico-social establishments (EHPAD nursing homes, disabled-persons facilities, home care services).

Its core technology platform is the PMSI (Programme de médicalisation des systèmes d'information), a hospital information system comprising standardized data collection formats, proprietary grouping algorithms that classify patient records into medico-economic categories (GHM, GHJ, GHPC), and the annual Etudes Nationales de Coûts (ENC) that produce cost scales by homogeneous patient group. These classifications form the operational basis of the T2A (tarification à l'activité) activity-based reimbursement system used to finance French healthcare establishments. Supporting infrastructure includes DRUIDES data-transmission software, the e-PMSI electronic transmission platform, and a unified three-tier data access layer — Data ATIH — comprising Data Essentiel (open interactive visualizations), Data Avancé (authenticated thematic applications), and Data Expert (restricted raw national database access). Additional offerings cover nomenclature management (CCAM, CIM-10, CIM-11), E-SATIS patient satisfaction surveys, performance dashboards for medico-social establishments, and the Dictionnaire des variables.

ATIH is fully funded by the French government through annual appropriations and provides all services free of charge to its customers, which are exclusively public-sector entities: public and private healthcare establishments (mandated to report), Regional Health Agencies (ARS), Assurance Maladie (for T2A reimbursement), Haute autorité de santé (HAS), CNSA, the Ministry of Health, DREES, and oversight bodies (CNIL, IGAS). The agency is led by Director General Nathalie Fourcade. Distribution is entirely domestic (France only) and operates through digital self-serve channels — open data portals, authenticated documentation platforms, downloadable software, and a support service — with no commercial sales motion, no external investors, no funding rounds, and no M&A activity.

Scale indicators10 records

Recent moves6 records

Expansion highlights5 records

Emerging players

• Health Data Hub: France's national health data platform enabling secondary use of health data for research and AI. Overlaps directly with ATIH on PMSI data access and analytics enablement, positioning it as both a partner and a potential substitute for parts of ATIH's mandate.

Regional players

• DREES (Direction de la recherche, des études, de l'évaluation et des statistiques): French Ministry of Health's statistical directorate producing health and social protection statistics; a core ATIH partner that publishes derived analyses from PMSI data — overlapping on health data publication and policy evaluation in the same national market.
• Santé Publique France: The French national public health agency responsible for disease surveillance, health monitoring, and population health analytics — comparable to ATIH on population-level health data analysis but focused on epidemiology rather than hospital financing.

Direct peers

• NHS England (formerly NHS Digital): The statutory health IT and data agency for England, operating national hospital data collection, clinical coding standards (similar to PMSI), and reimbursement-adjacent datasets. Closest international analogue to ATIH in mandate, scope, and public-sector ownership.
• Australian Institute of Health and Welfare (AIHW): Australia's national agency for health and welfare statistics, producing hospital activity data, expenditure reports, and performance indicators — directly comparable to ATIH's data dissemination mandate across MCO/SMR/PSY/HAD.
• Canadian Institute for Health Information (CIHI): An independent, not-for-profit organization that collects and analyzes Canadian health data, including hospital activity classification systems (CMG+) and financial reporting analogous to ATIH's GHM and ENC frameworks.

Others

• Statistics Netherlands (CBS): The Dutch national statistics office producing health sector statistics and hospital activity datasets; less directly comparable to ATIH but shares the public-sector, national-mandate data infrastructure role in the European health statistics ecosystem.

Broad incumbents

• IQVIA: A global commercial health data analytics leader covering hospital activity, claims, and pharmaceutical data — overlaps with ATIH in large-scale standardized health datasets and analytics, but operates as a commercial, international incumbent versus ATIH's national mandate.
• Agency for Healthcare Research and Quality (AHRQ): The US federal agency for healthcare quality, safety, and data analytics; broader scope than ATIH but overlaps in national hospital data production, quality indicators, and evidence-based care research used for policy decisions.
• Premier Inc. A US healthcare data and performance improvement company operating clinical, financial, and supply chain analytics across thousands of hospitals; comparable to ATIH in operating hospital performance and benchmarking datasets, but as a commercial entity.
