Description of intervention(s) / exposure
This study is a Double Blind Randomised Controlled Trial ( RCT) where practices are randomly allocated to:
- Group 1 ( intervention with spirometry) For 12 months practices will receive full spirometry intervention and an interpretation of results will be notified to the treating GP
-Group 2 (intervention without spirometry) For 12 months practices will receive spirometry before and after the trial, but no results will be reported to the GP

Group 3 (Control) For 12 months practices will provide usual medical care only, which may include peak flow monitoring, but not spirometry

Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will be concealed by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computerised sequence generation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
three armed design - chosen because of a desire to investigate Forced Expiratory Volume in one second (FEV1) as a secondary outcome but concern about possible Hawthorne effects from participants attending a testing centre and having spirometry performed. The intervention will be concealed from GP's up to the time of recruitment and will be kept masked from patients and research staff performing oucome assessments.
