In 2004 the first National Institute for Health and Clinical Excellence (NICE) guidelines for chronic obstructive pulmonary disease (COPD) were published. They have recently been revised taking into account further evidence and publications. This article details the updated changes relevant to current practice alongside previous relevant recommendations. NICE guidance informs best practice but it does not negate our individual circumstances and responsibility and as practitioners we have a duty of care to be aware of the latest guidance.
