COPD 001.1 Rational

A diagnosis of COPD is considered in any patient who has symptoms of persistent cough, sputum production, or dyspnoea and/or a history of exposure to risk factors for the disease. The diagnosis is confirmed by post bronchodilator spirometry.

See COPD002.1

Where patients have a long-standing diagnosis of COPD and the clinical picture is clear, it would not be essential to confirm the diagnosis by spirometry in order to enter the patient onto the register. However, where there is doubt about the diagnosis practices may wish to carry out post bronchodilator spirometry for confirmation.

NICE clinical guideline 101 recommended a change to the diagnostic threshold for COPD in 2010 (see table 2).

Table 2: Gradation of severity of airflow obstruction

NICE clinical guideline 12 (2004)
ATS/ERS(43) 2004
GOLD 2008(44)
NICE clinical guideline 101 (2010)
Post-bronchodilator FEV1/FVC
FEV1 % predicted
Severity of airflow obstruction
< 0.7
Stage 1 Mild
Stage 1 Mild*
< 0.7
Stage 2 Moderate
Stage 2 Moderate
< 0.7
Stage 3 Severe
Stage 3 Severe
< 0.7
< 30%
Very Severe
Stage 4 Very severe**
Stage 4 Very severe**

*Symptoms should be present to diagnose COPD in people with mild airflow obstruction (see recommendation

**Or FEV1 (Forced expiratory volume in one second) < 50% with respiratory failure.

COPD 001.2 Reporting and verification

See indicator wording for requirement criteria.

Where patients have co-existing COPD and asthma they will be included on both disease registers. Approximately 15 per cent of patients with COPD will also have asthma.
