Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. It is estimated that over three million people in the UK have the disease, with just under a third actually having a diagnosis (National Institute for Health and Care Excellence [NICE], 2010a). It is defined as irreversible air flow obstruction, which is insidious and progressive with little day-to-day variability, predominantly caused by cigarette smoking, but with the recognition of ther contributory factors such as exposure to occupational irritants (NICE, 2010a).

Reducing the burden of COPD relies on early and accurate diagnosis before individuals are on the trajectory of functional decline (Department of Health [DH], 2011). This paper outlines the key steps that general practice nurses (GPNs) should take to make a good diagnosis and so make lifelong improvements for patients living with COPD.
