Hyperbaar Geneeskundig Centrum

What Hyperbaar Geneeskundig Centrum does

Hyperbaar Geneeskundig Centrum (HGC) is a Dutch specialist clinic operating since June 2013 from a single facility in Rijswijk, Netherlands. It delivers hyperbaric oxygen therapy (HBOT) — patients breathe 100% oxygen at 1.5–3 times atmospheric pressure inside a multiplace chamber — to treat three core medical indications covered by Dutch basic health insurance: late radiation tissue damage following cancer radiotherapy, chronic (diabetic) non-healing wounds, and chronic osteomyelitis. HGC operates the largest multiplace hyperbaric chamber in the Netherlands, capable of treating 20 patients simultaneously plus 4 ICU patients in parallel (supplied by IHC Hytech), and complements HBOT with an integrated wound polyclinic staffed by surgeons, vascular surgeons, wound care nurses, a plaster technician, and edema therapists. The center treats 80–100 patients per day with a team of approximately 40 employees.

The business model is reimbursement-driven under the Dutch basic health insurance system, with revenues flowing through agreements with eleven named health insurers (Zilveren Kruis/Achmea, CZ, VGZ, Menzis, DSW, ASR, FBTO, Interpolis, Salland, Anderzorg, Nationale-Nederlanden) for the three insured indications. Long COVID treatment is provided off-label on a self-pay basis. All patient acquisition is referral-driven: patients enter exclusively via medical specialists or GPs, and HGC has formalized cooperation agreements with a broad network of Dutch regional hospitals and academic centers (Erasmus MC, LUMC, Amsterdam UMC, HagaZiekenhuis, Reinier de Graaf, Groene Hart, among others). The center is legally organized as Stichting Hyperbaar Geneeskundig Centrum, a Dutch foundation led by Medical Director drs. René Bol Raap and surgeon Dr. P.C. Casper Smit, with a Supervisory Board.

HGC is operationally distinct from the eight other Dutch HBOT centers due to its chamber scale, integrated wound polyclinic, and research program. It maintains peer-reviewed publications, ZKN Keurmerk and KIWA certification, WTZA healthcare institution classification (instellingsnummer 10989), BIG-registered physicians, and active research collaborations with TU Delft (oxygen gas recovery and 3D-printed woundcare footwear) and Erasmus MC (long COVID register study). Patient satisfaction scores have remained consistently high (8.9/10 in 2024, NPS 77 in 2015).

Revenue model

1. Hyperbare zuurstoftherapie (HBOT) — Insured Medical Treatment: Hyperbare zuurstoftherapie is classified as a medical treatment covered by Dutch basic health insurance (basiszorgverzekering) for recognized indications such as late radiation tissue damage, chronic non-healing wounds, and chronic osteomyelitis. Treatment requires a referral from a medical specialist or GP. Patients do not pay out-of-pocket for covered indications. Revenue flows through reimbursement agreements with Dutch health insurers including Zilveren Kruis/Achmea, CZ, VGZ, Menzis, DSW, ASR, FBTO, Interpolis, Salland, Anderzorg, and Nationale-Nederlanden. Long COVID is currently not an approved indication and thus not covered.
