Swansea’s Morriston Hospital is leading the fight against an increasing worry worldwide: resistance to antibiotics.
Antibiotics can be a vital part of treatment. But often they continue to be given to patients when there is no longer a clinical need.
That can cause antibiotic resistance and leave people at risk of unpleasant infections like C. difficile (sometimes known as C. diff), which causes diarrhoea.
A five-year research programme designed by Oxford University, started in 2015.
Its aim is to reduce serious infections caused by antibiotic resistance in the future, by safely reducing antibiotic use in hospitals now.
Morriston is one of two Welsh hospitals to be selected for the final phase of the programme. A three-month pilot started this month.
