Most patients attending urgent treatment centres, walk-in centres and minor injury units are assessed, treated and discharged during their visit, with information shared with their GP where appropriate to ensure continuity of care, according to NHS Sussex.
People do not need to be registered with a GP or have a fixed address to use these services, it added.
Fordham added: “Making the right choice really can make all the difference during a busy winter period.
“I would encourage people to familiarise themselves with the urgent care services near them, so they feel confident about using the right service at the right time.”
Across East Sussex and West Sussex, urgent care services are available in communities including Brighton and Hove, Lewes, Crawley, Crowborough, Uckfield, Horsham, Bognor Regis and East Grinstead, with many services open seven days a week.
