Symptoms, Treatment Step and
Admission Rates in 12,203 UK Asthmatics

Presented at the
World Asthma Conference,
December 1998 at Barcelona

Neville R G, McCowan C, Hoskins G, Thomas G E


What is this project about?

Asthma is a major health problem in the UK. The majority of UK asthmatics are managed in Primary Care by General Practitioners (GPs) and Practice Nurses. Since the introduction of Guidelines using treatment Step there has been a need to review how many patients are at each guideline step, the presence of symptoms, asthma attack and hospital admission rates.

This should enable GPs to target those patients most in need of clinical review to reassess treament.

What did we do?

The Asthma Research Unit, University of Dundee, has worked with GPs throughout the UK to review how and where asthma is managed.  The symptoms, treatment step, asthma attack and admission rates of 12,203 asthmatics of all ages was studied.   Results were analysed by age band to build up a picture of which patients might benefit from in depth clinical review.

Abstract

The UK National Asthma Management Study reviewed symptoms, treatment and health service use in 12,203 asthmatics of all ages managed in primary care. Hospital admission rates per year were age <5 10.4%, age 5-15 2.1%, age 16-30 2.2%, age 31-44 1.96%, age 45-64 2.9% and age >65 4.1%. The attack rate was relatively constant across age bands (18%-35%) indicating substantial age specific variation in admission rate per attack ie. 30.95% of attacks in under 5’s resulted in admission in constrast to in all other age groups.

On routine clinical assessment current asthma symptoms indicating a need to review management were present in under 5’s 34.1%, age 5-15 29.4%, 16-33 41.4%, 31-44 47.5%, 45-64 49.8% and aged >65 56.9%.

Despite the widespread distribution of asthma guidelines in the UK there is still widespread evidence of undertreatment resulting in poor symptom control and an unacceptably high admission rate, particularly in the under 5’s

What does it mean?

A substantial proportion of UK asthmatics report current symptoms (Cough, Wheeze or breathlessness).

Asthma attacks are common in all age groups but a greater proportion of young children are amitted to hospital with asthma attacks than adults.

Despite the widespread distribution of Guidelines a substantial proportion of UK asthmatics deserve a detailed clinical review and consideration of alteration to therapy.
