Underdiagnosis of COPD

Nacul et al. J Pub Health 2010

The ratio of diagnosed to expected prevalence varied from 0.20 to 0.95, mean of 0.52. Underdiagnosis was more pronounced in urban areas, and was particularly severe in London

Raising Awareness & Encouraging Testing Know it. Check it. Treat it.

Using a combination of centrally coordinated and locally-led activities the campaign aims to:

• Generate HCP endorsement for the campaign to support doctors, nurses, carers and community pharmacists when talking to people about COPD

• Raise awareness of COPD terminology and its symptoms among the target audience

• Help people link their symptoms (and those of people they care for) to the disease in order to drive patient presentations

• Demonstrate the positive health benefits that can be gained if people seek help and offer a clear route for getting help

• Illustrate the benefits of optimal COPD care for those already diagnosed but who are still breathless
