Castel launches pilot multidisciplinary healthcare clinic in Sydney, Australia
Castel has launched a 50-day pilot of a new healthcare infrastructure model in Cammeray, Sydney, in partnership with Kieser Australia and initially operating under The Osteoarthritis (OA) Hub brand.
The model allows independent clinicians to operate their practices within shared healthcare hubs while The OA Hub provides the infrastructure around them, including consulting rooms, reception, administration, billing, clinical systems, AI software, consumables and practice growth support. Clinicians retain ownership of their practices and full clinical autonomy.
The pilot will initially support rheumatology services and will test the model ahead of a potential broader rollout.
