Asthma – Diagnosis


INTRODUCTION

The effective treatment of asthma depends on the correct diagnosis being made in the first place. In 2019 the British Thoracic Society (BTS) and the Scottish Intercollegiate Guidelines Network (SIGN) published their latest guidance on asthma, which included their recommendations on how to take a structured approach to diagnosis.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.
