DEFINITION CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Preventable Treatable

PERSISTENT

Chronic

Response not Reversible

This definition does not use the terms chronic bronchitis and emphysema and excludes asthma (reversible airflow limitation).

DEFINITION CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Chronic bronchitis, defined as the presence

of cough and sputum production for at least

3 months in each of 2 consecutive years, is

not necessarily associated with airflow

limitation.Emphysema, defined as destruction of the alveoli.

DIAGNOSIS OF COPD

+ SPIROMETRY (Air flow limitation)Simple test to measure the amount of air a

person can breathe out, and the amount of time taken to do so. FVC (Forced Vital Capacity): maximum volume of air

that can be exhaled during a forced maneuver. FEV1 (Forced Expired Volume in one second):

volume expired in the first second of maximal expiration after a maximal inspiration. This is a measure of how quickly the lungs can be emptied.

FEV1/FVC: FEV1 expressed as a proportion of the FVC, gives a clinically useful index of airflow limitation.

DIAGNOSIS OF COPD

WHY DO SPIROMETRY FOR COPD?

Spirometry is needed to make a clinical diagnosis of COPD.

A normal value for spirometry effectively excludes the diagnosis of clinically relevant COPD.

Together with the presence of symptoms, spirometry helps gauge COPD severity and can be a guide to specific treatment steps.

ASSESMENT OF COPD

• Degree of airflow limitation (using spirometry) • Risk of exacerbations• Comorbidities

COMBINED COPD ASSESMENT

• Symptoms (impact on patient’s health status)

• Degree of airflow limitation • Risk of exacerbations• Comorbidities

COMBINED COPD ASSESMENT

When assessing risk, choose the highest risk according to GOLD

grade or exacerbation history. (One or more hospitalizations

for COPD exacerbations should be considered high risk.

Patient Group A – Low Risk, Less Symptoms

Typically GOLD 1 or GOLD 2 (Mild or Moderate airflow limitation) and/or 0-1 exacerbation per year and mMRC grade 0-1 or CAT score < 10

Patient Group B – Low Risk, More Symptoms

Typically GOLD 1 or GOLD 2 (Mild or Moderate airflow limitation) and/or 0-1 exacerbation per year and mMRC grade ≥ 2 or CAT score ≥ 10

Patient Group C – High Risk, Less Symptoms Typically GOLD 3 or GOLD 4 (Severe or Very

Severe airflow limitation) and/or ≥ 2 exacerbations per year and mMRC grade 0-1 or CAT score < 10

Patient Group D – High Risk, More

Symptoms Typically GOLD 3 or GOLD 4 (Severe or Very

Severe airflow limitation) and/or ≥ 2 exacerbations per year and mMRC grade ≥ 2 or CAT score ≥ 10

Example: Imagine a patient with a CAT score of 18, FEV1 of 55% of predicted, and a history of 3 exacerbations within the last 12 months.
