COPD 004.1 Rationale

There is a gradual deterioration in lung function in patients with COPD. This deterioration accelerates with the passage of time. There are important interventions which can improve quality of life in patients with severe COPD. It is therefore important to monitor respiratory function in order to identify patients who might benefit from pulmonary rehabilitation or continuous oxygen therapy.

NICE clinical guideline 101 recommends that FEV1 and inhaler technique should be assessed at least annually for people with mild/moderate/severe COPD (and in fact at least twice a year for people with very severe COPD). The purpose of regular monitoring is to identify patients with increasing severity of disease who may benefit from referral for more intensive treatments/diagnostic review.

Further information
NICE clinical guideline 101 (2010). Chronic obstructive pulmonary disease. See table six.

Contractors should identify those patients who could benefit from long term oxygen therapy and pulmonary rehabilitation.

These measures require specialist referral because of the need to measure arterial oxygen saturation to assess suitability for oxygen therapy, and the advisability of specialist review of patients prior to starting pulmonary rehabilitation.

The long term administration of oxygen (more than 15 hours per day) to patients with chronic respiratory failure has been shown to increase survival and improve exercise capacity.

Referral for consideration for long term oxygen therapy and/or pulmonary rehabilitation should be made to those with appropriate training and expertise. This may include a respiratory physician, a general physician or a GP with a special interest (GPwSI) in respiratory disease. The specific clinical criteria for referral for long term oxygen therapy and pulmonary rehabilitation are set out in NICE clinical guideline CG101.
