GIST

What GIST does

GIST (Groupement Interprofessionnel de Santé au Travail) is a French inter-company occupational health service (Service de Prévention et de Santé au Travail Interentreprises, or SPSTI) operating as a non-profit association under the law of July 1, 1901. Founded in 1953 and headquartered at 28 Rue des Chantiers in Saint-Nazaire, GIST delivers legally mandated occupational health services to employers across the Loire-Atlantique territory, covering Saint-Nazaire, Pont-Château, Blain, La Baule, and the Guérande peninsula through four medical centers. The organization holds a government-issued accreditation (Agrément 2025-2030) and operates under a multi-year contractual framework (CPOM 2025-2029) with the DRIEETS.

GIST's service portfolio is organized around an "Offre Socle" (Core Offer) comprising three pillars: (1) individual health monitoring (suivi individuel de l'état de santé), including medical visits and fitness assessments; (2) professional risk prevention (prévention des risques professionnels), including workplace assessments and DUERP support; and (3) prevention of professional disinsertion (cellule PDP). The organization supplements this core with 20+ training workshops and awareness sessions per year, a dedicated e-learning module library, and a specific offering for self-employed workers. The technology backbone consists of specialized SPSTI software (Health at Work and Pulse) for medical file management, the digital occupational health medical file (DMST), and a member portal (adherent.gist44.fr) with HTTPS encryption, role-based access controls, and RGPD-compliant data handling. GIST is AFNOR SPEC2217 Level 1 certified and GDPR compliant.

The business model is a regulated, subscription-based membership structure: employers pay an annual cotisation scaled to workforce size, covering the full core service offering. GIST serves 7,567 member companies and monitors 76,688 workers (some sources cite 80,000-85,000) across all sectors, supported by a multidisciplinary team of approximately 95 collaborators — including 15 occupational physicians, 14 nurses, 19 risk prevention specialists (IPRP), and 25 medical assistants, plus ergonomists, psychologists, and hygienists. GIST is governed by a Board of Directors representing member companies and operates within the Présanse Pays de la Loire network of inter-company occupational health services. The organization has no external shareholders, no venture capital exposure, and no M&A activity; it is a member-owned, regulated utility-like entity.
