Ahead of what is expected to be a busy weekend, there is a focus on 'freeing up hospital emergency departments' to 'treat those in most need'.
Dr Elizabeth Gill, chief medical officer for the Sussex Clinical Commissioning Groups said: “It’s important to remember that if you need medical help the NHS is here for you.”
Patients needing a face-to-face appointment with a health professional are being asked to call NHS 111 first, who will help direct people to the most appropriate service for treatment.
NHS 111 by phone or online at nhs.uk, available 24/7 and offers advice and guidance for patients experiencing non-emergency, urgent healthcare needs.
