UCC
The government helpfully suggests that we should use the initialism UCC for this special clinic (the Urgent Care Clinic) that deals with illnesses, medical conditions and accidents that are not life-threatening and do not require an ambulance to take the patient directly to hospital, but that are serious enough to require immediate attention so that taking time to visit the GP is not an option. They provide care that comes between the hospital and the general practice. They are walk-in centres which do not require an appointment or a referral. You can either visit the centre or talk to the staff on the phone. This is the intermediate health service promised by the Labor Government to take the load off hospitals.
