What zas - ziekenhuis aan de stroom does

Ziekenhuis aan de Stroom (ZAS) is a non-profit hospital network headquartered in Antwerp, Belgium, formed in July 2024 through the merger of Ziekenhuis Netwerk Antwerpen (ZNA) and GZA Ziekenhuizen. ZAS operates 14 campuses plus polyclinics across the Antwerp metropolitan area, supported by 3,300 licensed beds, approximately 9,000 staff, and 1,000 doctors. The network is the largest hospital in Belgium and one of the five largest in Europe by scale, and it provides the full spectrum of clinical services — emergency care across five emergency departments plus two first aid centers (handling 209,427 emergency patients in 2024), oncology (including the largest breast cancer clinic in Belgium at ZAS Augustinus and the largest cancer treatment centre in Flanders), cardiac care (Cardiolounge), pediatrics (ZAS Paola Children's Hospital), psychiatry (ZAS PZ Stuivenberg, ZAS UKJA), organ donation coordination, and specialised services such as the Stresskliniek and maritime medicine at ZAS Kaai 142. The underlying digital infrastructure consists of a unified Electronic Patient Dossier (EPD) rolled out across all campuses since 2022 and the Mijn ZAS patient portal for appointment booking, records access, and provider communication.

ZAS generates revenue through regulated Belgian healthcare reimbursement — primarily via RIZIV/INAMI payments, patient co-payments (remgeld), hospitalisation insurance, and mutualities — supplemented by procurement and supplier-side flows processed through the Peppol e-invoicing network. Its go-to-market is direct-to-consumer and referral-based: patients access services through 14 campuses, 3 polyclinics, the online portal, GP and specialist referrals, or 24/7 emergency departments. The customer base is the general Antwerp regional population across multiple segments (general, pediatric, oncology, emergency, mental health, organ donation). Notable operational investments include the EUR 87M ZAS Palfijn new build (maternity, geriatrics, oncology day hospital), EUR 860,000 in solar infrastructure across four campuses, and strategic partnerships with Universitair Ziekenhuis Antwerpen (UZA), Iridium Kankernetwerk, RevArte, and federal/Flemish health authorities for data sharing and clinical coordination.
