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

Global Strategy for Diagnosis Management and Prevention of 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
bull Exacerbations increase the decline in lung function deterioration in health status and risk of death the assessment of exacerbation risk can also be seen as an assessment of the risk of poor outcomes in general

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

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

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

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

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

Global Strategy for Diagnosis Management and Prevention of COPD
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

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

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

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

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

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

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

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

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

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

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
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

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

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

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

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

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

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

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

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
Global Strategy for Diagnosis Management and Prevention of COPD
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
These comorbid conditions may influence mortality and
hospitalizations and should be looked for routinely and
treated appropriately copy 2014 Global Initiative for Chronic Obstructive Lung Disease

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
Global Strategy for Diagnosis Management and Prevention of COPD
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
These comorbid conditions may influence mortality and
hospitalizations and should be looked for routinely and

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

Oxygen titrate to improve the patientrsquos hypoxemia with a
target saturation of 88-92
Bronchodilators Short-acting inhaled beta2-agonists with or
without short-acting anticholinergics are preferred
Systemic Corticosteroids Shorten recovery time improve
lung function (FEV1) and arterial hypoxemia (PaO2) and
reduce the risk of early relapse treatment failure and length
of hospital stay A dose of 40 mg prednisone per day for 5
days is recommended

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
