UHS researchers are leading a large study to reduce children’s overuse of reliever inhalers linked to severe asthma attacks.
Children with asthma who use a high number of blue reliever inhalers are several times more likely to have severe asthma attacks, which can be life-threatening.
The Prescription Alerts for Reliever Inhalers in Children (PARC) is offering these children an enhanced check-up, led by a specialist nurse.
The research is assessing if this extra check-up reduces the number of asthma or wheeze attacks these children have. It is the first time this issue has been formally studied.
The PARC study is led by Dr Anna Selby, a Paediatric Registrar at UHS and NIHR Academic Clinical Lecturer at the University of Southampton.
She said: “This study is the first of its kind to test whether a simple, proactive check-up can prevent severe asthma attacks in children and young people. Our hope is that by identifying children at higher risk sooner, and giving families extra support and education, we can reduce emergency admissions and transform how asthma care is delivered across the UK.”
