For management of acute asthma or wheeze please see the Asthma - acute (including wheeze) page.
For adults please see the Asthma (adults) page
The diagnosis of asthma should be made after taking a structured clinical history. Asthma may be suspected in children with variable wheezing, noisy breathing, cough, breathlessness or chest tightness. Information should be sought about triggers for symptoms and family history of asthma or allergic rhinitis. In children with a history consistent with asthma supportive objective testing should be sought to confirm this diagnosis.
Children under 5 years
For children under 5 with suspected asthma (interval symptoms and another atopic disorder or severe acute episodes requiring admission/oral steroids), treat with an 8-12 week trial of twice daily low dose inhaled corticosteroids and review the child at least annually. If they still have symptoms when they reach 5 years, attempt objective testing.
Children 5-16 years
Objective tests should be ordered and interpreted as below
See pages 3-6 of the UHBW Asthma: diagnosis and management of Chronic Asthma guidelines for details (flow pathway on page 6).This includes a differential diagnosis guide for children with persistent or recurrent wheeze.
Access to objective testing
Children with asthma can usually be diagnosed without spirometry. There is no direct access to secondary care skin prick testing, spirometry or a FeNO service for children in BNSSG and requests to paediatrics for these tests will be returned. Access to spirometry should be available over the course of 25/26 in general practice. There is some access to FeNO in general practice
Referral for a paediatric opinion or further testing should only be considered if there is poor response to treatment or diagnostic uncertainty (see Who to Refer section below).
The majority of children and young people with asthma can be managed in primary care.
See BNSSG Asthma Prescribing Guidelines 2025 – Children & Young People.
MHRA Guidance on use of SABA : Healthcare professionals should be aware of the change in guidance that no longer recommends prescribing SABA without an inhaled corticosteroid.
Local Asthma action plans have been developed in BNSSG. These should be download and given to parents to support acute management:
Children under 5 years
Refer for specialist assessment if the child's asthma does not respond to low dose ICS trial or if after a positive response is uncontrolled on a paediatric moderate dose of ICS as maintenance therapy and a trial of an LTRA has been unsuccessful or not tolerated, stop the LTRA and refer the child to a specialist in asthma care for further investigation and management after checking inhaler technique / adherence / environmental triggers.
Refer for specialist assessment any preschool child with an admission to hospital, or 2 or more admissions to an emergency department, with wheeze in a 12-month period
Children 5-16 years
If there is still doubt about the diagnosis, after a structured clinical history and objective testing refer to a paediatric specialist for a second opinion.
Refer children if their asthma is not controlled on paediatric moderate-dose MART or paediatric moderate-dose ICS/LABA maintenance treatment (with or without an LTRA depending on previous response).
For children with indications for referral, referral can be made via eRS. If age 16 years or over then refer to adult services.
Children with hospital admission for asthma or 2 ED presentations in 12 months should be followed in secondary care asthma clinic.
See page 13 of the UHBW Asthma: diagnosis and management of Chronic Asthma guidelines for details of children who may benefit from referral to the severe asthma clinic in tertiary paediatric respiratory care.
