Asthma – Diagnosis

INTRODUCTION

The effective treatment of asthma depends on correct diagnosis. The joint guideline from the British Thoracic Society (BTS), NICE and the Scottish Intercollegiate Guidelines Network (SIGN), emphasises the importance of objective tests to support a diagnosis in people with suspected asthma, or to confirm the diagnosis in people who are not responding to therapy.¹ 

General practice nurses (GPNs) who have the relevant training and competencies are often involved in diagnosing people who present with respiratory symptoms and a clear understanding of how the diagnosis is made is therefore essential. In people who already have a diagnosis of asthma, it is worth reviewing the diagnosis if they are poorly controlled despite asthma treatment – so in essence anyone involved in the care of people with asthma should be aware of how the diagnosis is reached.
