The operation submitted concerns two projects: Under the leadership of the ARS Grand-Est, the main health facilities of Aube and Sézannais decided to pool their means to create a pharmacy for common indoor use. This territorial UIP concerns the following establishments: Centre Hospitalier de Troyes, Groupement Hospitalier Aube-Marne (GHAM), Public Mental Health Institution (EPSM), Centre Hospitalier de Bar-sur-Seine (BSS), Centre Hospitalier de Bar-sur-Aube (BSA), GCS Platform d’Aval Territory Champagne Sud, GCS Tep Scan and GCS Clinique de Champagne. The Troyes CH and GHAM laboratories are now grouped into a public-media GCS. With a view to COFRAC accreditation, the objective pursued by the creation of this group was to operate a unique multi-site medical biology laboratory. Other HCS establishments treat biology to private laboratories.
