Centre Hospitalier Privé Sainte-Marie - Vivalto Santé

What Centre Hospitalier Privé Sainte-Marie - Vivalto Santé does

Centre Hospitalier Privé Sainte-Marie (CHP Sainte-Marie) is a private surgical and oncology hospital located in Osny, Val-d'Oise, in the Île-de-France region of France, founded in 1930 and operating as a wholly-owned subsidiary of Groupe Vivalto Santé under a single-shareholder SAS structure (registered capital €4,275,000). The facility is sited on an 8-hectare health campus and delivers care across three core pillars: surgery (general, urological, gynecological, and specialized hand surgery via its Urgences Mains unit), oncology (chemotherapy administration and a dedicated senology/breast cancer unit), and 24/7 emergency services handling approximately 10,000 annual visits. Supporting clinical services include the Institut de la Douleur – VivalGo (pain management), the SOS Calcul emergency pathway for urinary calculi, the RRAAC enhanced-recovery-after-surgery protocol, and pediatric and ambulatory care pathways.

The hospital's technology layer is primarily digital-patient-facing rather than AI-driven: an online pre-admission system, online payment portal via portail.vivalto-sante.com, and a forthcoming tele-expertise service that allows general practitioners to request specialist opinions remotely. There are no public APIs, no proprietary AI models, and no disclosed developer-facing integrations; the digital stack is shared at the Vivalto Santé group level.

CHP Sainte-Marie operates as a conventioned French private healthcare facility under the national social security regime, generating revenue from surgical, oncological, and emergency services with patient contributions covering the ticket modérateur, forfait journalier, hotel supplements, and occasional practitioner dépassements d'honoraires, supplemented by mutuelle coverage. Direct-to-patient go-to-market is executed through emergency presentations, online-bookable specialist consultations, GP referrals, and the emerging tele-expertise channel; the establishment is ranked 14th nationally for adult testicular surgery, 22nd for hand emergencies, and 38th for cataract surgery in the 2025 Le Point rankings, and reports a 98/100 Gender Equality Index.
