Global Strategy for Diagnosis Management and Prevention of COPD

Definition of COPD

COPD a common preventable and treatable disease is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases

Exacerbations and comorbidities contribute to the overall severity in individual patients

Heterogeneity of COPD

- Genetic Phenotypes - Although smoking is the major risk factor for the development of COPD the development of airflow obstruction in smokers is highly variable Severe 1 antitrypsin deficiency is a proven genetic risk factor for COPD - Familial aggregation of airflow obstruction within families of COPD patients has also been demonstrated - A recent association study comprising 8300 patients and 7 separate cohorts found that a minor allele SNP of MMP12 (rs2276109) associated with decreased MMP-12 expression has a positive effect on lung function in children with asthma and in adult smokers - Recent genome-wide association studies have identified several COPD loci including a region near the hedgehog interacting protein (HHIP) gene on chromosome 4 and a cluster of genes on chromosome 15 that likely contain COPD susceptibility determinants

Heterogeneity of COPD

- Allergy Phenotypes

- In the National Health and Nutrition Survey III

(NHANES III) individuals with an allergic phenotype were more likely to wheeze and have chronic cough and phlegm and increased risk of exacerbations - In the COPD and Domestic Endotoxin (CODE) cohort sensitized subjects reported more wheeze cough-induced nocturnal awakenings and exacerbations and acute health visits - Active allergic symptoms may worsen the course of COPD - Allergen avoidance or pharmacologic treatment of allergic disease is warranted in specific subjects with COPD

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Assessment of Airflow Limitation Spirometry

Spirometry should be performed after the administration of an adequate dose of a short- acting inhaled bronchodilator to minimize variability

A post-bronchodilator FEV1FVC lt 070 confirms the presence of airflow limitation

Where possible values should be compared to age-related normal values to avoid overdiagnosis of COPD in the elderly

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Definition of COPD

COPD a common preventable and treatable disease is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases

Exacerbations and comorbidities contribute to the overall severity in individual patients

Heterogeneity of COPD

- Genetic Phenotypes - Although smoking is the major risk factor for the development of COPD the development of airflow obstruction in smokers is highly variable Severe 1 antitrypsin deficiency is a proven genetic risk factor for COPD - Familial aggregation of airflow obstruction within families of COPD patients has also been demonstrated - A recent association study comprising 8300 patients and 7 separate cohorts found that a minor allele SNP of MMP12 (rs2276109) associated with decreased MMP-12 expression has a positive effect on lung function in children with asthma and in adult smokers - Recent genome-wide association studies have identified several COPD loci including a region near the hedgehog interacting protein (HHIP) gene on chromosome 4 and a cluster of genes on chromosome 15 that likely contain COPD susceptibility determinants

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

Definition of COPD

COPD a common preventable and treatable disease is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases

Exacerbations and comorbidities contribute to the overall severity in individual patients

Heterogeneity of COPD

- Genetic Phenotypes - Although smoking is the major risk factor for the development of COPD the development of airflow obstruction in smokers is highly variable Severe 1 antitrypsin deficiency is a proven genetic risk factor for COPD - Familial aggregation of airflow obstruction within families of COPD patients has also been demonstrated - A recent association study comprising 8300 patients and 7 separate cohorts found that a minor allele SNP of MMP12 (rs2276109) associated with decreased MMP-12 expression has a positive effect on lung function in children with asthma and in adult smokers - Recent genome-wide association studies have identified several COPD loci including a region near the hedgehog interacting protein (HHIP) gene on chromosome 4 and a cluster of genes on chromosome 15 that likely contain COPD susceptibility determinants

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Heterogeneity of COPD

- Genetic Phenotypes - Although smoking is the major risk factor for the development of COPD the development of airflow obstruction in smokers is highly variable Severe 1 antitrypsin deficiency is a proven genetic risk factor for COPD - Familial aggregation of airflow obstruction within families of COPD patients has also been demonstrated - A recent association study comprising 8300 patients and 7 separate cohorts found that a minor allele SNP of MMP12 (rs2276109) associated with decreased MMP-12 expression has a positive effect on lung function in children with asthma and in adult smokers - Recent genome-wide association studies have identified several COPD loci including a region near the hedgehog interacting protein (HHIP) gene on chromosome 4 and a cluster of genes on chromosome 15 that likely contain COPD susceptibility determinants

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Heterogeneity of COPD

FEV1 (forced expiratory volume in 1 sec) is the

hallmark of COPD because it is affected by inflammation and remodeling of the small airways as well as by emphysematous destruction of the terminal airspaces however defining a disease as COPD so heterogeneous exclusively based on the patientrsquos FEV1 may not always be adequate

Heterogeneity of COPD

bull COPD is a diverse disease with many clinical radiological and genomic features that may designate several different phenotypes that may have prognostic as well as therapeutic implications

bull Chest CT uses lung structure to characterize the COPD population into emphysema or airway-predominant phenotypes that may provide keen insight into disease progression and response to therapy

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Heterogeneity of COPD

FEV1 (forced expiratory volume in 1 sec) is the

hallmark of COPD because it is affected by inflammation and remodeling of the small airways as well as by emphysematous destruction of the terminal airspaces however defining a disease as COPD so heterogeneous exclusively based on the patientrsquos FEV1 may not always be adequate

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Assess Risk of Exacerbations

To assess risk of exacerbations use history of exacerbations and spirometry

Two or more exacerbations within the last year or an FEV1 lt 50 of predicted value are indicators of high risk

One or more hospitalizations for COPD exacerbation should be considered high risk

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Diagnosis and Assessment Key Points

A clinical diagnosis of COPD should be considered in any patient who has dyspnea chronic cough or sputum production and a history of exposure to risk factors for the disease

Spirometry is required to make the diagnosis the presence of a post-bronchodilator FEV1FVC lt 070 confirms the presence of persistent airflow limitation and thus of COPD

copy 2014 Global Initiative for Chronic Obstructive Lung Disease

Global Strategy for Diagnosis Management and Prevention of COPD

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Assess COPD Comorbidities

COPD patients are at increased risk for

bull Cardiovascular diseases bull Osteoporosis skeletal muscle dysfunction bull Respiratory infections bull Anxiety and Depression bull Diabetes metabolic syndrome bull Lung cancer bull Bronchiectasis

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Diagnosis and Assessment Key Points

The goals of COPD assessment are to determine the severity of the disease including (1) the severity of airflow limitation (2) the impact on the patientrsquos health status and (3) the risk of future exacerbations in order to guide therapy

The risk of future exacerbations estimated by the severity of airflow limitation and the history of previous exacerbations

Comorbidities occur frequently in COPD patients and should be actively looked for and treated appropriately if present

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival

Patients with symptoms disproportionate to the severity of obstruction (subgroup B) may be at higher risk of death

Evidence to support this classification system

bull Patients with a high risk of exacerbations tend to be in GOLD categories 3 and 4 (Severe or Very Severe airflow limitation) and can be identified quite reliably from the their own past history bull Higher exacerbation rates are associated with faster loss of FEV1 and greater worsening of health status bull Hospitalization for a COPD exacerbation is associated with poor prognosis bull CAT score ≧ 10 are associated with significantly

impaired health status

Additional Investigations

Imaging Chest X-ray Seldom diagnostic but valuable to exclude alternative diagnoses and establish presence of significant comorbidities Computed tomography (CT) of the chest Might help in DD when concomitant diseases exist

Lung Volumes and Diffusing Capacity Help to characterize severity but not essential to patient management

Oximetry and Arterial Blood Gases Pulse oximetry can be used to evaluate a patientrsquos oxygen saturation and need for supplemental oxygen therapy

Alpha-1 Antitrypsin Deficiency Screening Perform when COPD develops in patients of Caucasian descent under 45 years or with a strong family history of COPD

copy 2013 Global Initiative for Chronic Obstructive Lung Disease

Exercise Testing Objectively measured exercise impairment assessed by a reduction in self-paced walking distance (such as the 6 min walking test) or during incremental exercise testing in a laboratory is a powerful indicator of health status impairment and predictor of prognosis

Composite Scores Several variables (FEV1 exercise tolerance assessed by walking distance or peak oxygen consumption weight loss and reduction in the arterial oxygen tension) identify patients at increased risk for mortality The BODE (BMI Obstruction Dyspnea and Exercise) index is a better predictor of subsequent survival
