• Identication and reduction of exposure to risk factorsare important steps in the prevention and treatmentof COPD. All individuals who smoke should beencouraged to quit.

• The level of FEV$ is an inadequate descriptor of the

impact of the disease on patients and for this reasonindividualized assessment of symptoms and futurerisk of exacerbation should also be incorporated intothe management strategy for stable COPD.

• Pharmacologic therapy is used to reduce symptoms,reduce frequency and severity of exacerbations,and improve health status and exercise tolerance.

Existing medications for COPD have not beenconclusively shown to modify the long-term decline inlung function that is the hallmark of this disease.

• For both beta"-agonists and anticholinergics, long-

acting formulations are preferred over short-actingformulations. Based on efcacy and side effects,inhaled bronchodilators are preferred over oralbronchodilators.

• Long-term treatment with inhaled corticosteroidsadded to long-acting bronchodilators isrecommended for patients at high risk ofexacerbations.

• Long-term monotherapy with oral or inhaledcorticosteroids is not recommended in COPD.

• The phosphodiesterase-4 inhibitor roumilast may beuseful to reduce exacerbations for patients with FEV

< 50% predicted, chronic bronchitis, and frequentexacerbations.

• Inuenza vaccines can reduce the risk of seriousillness (such as hospitalization due to lowerrespiratory tract infections) and death in COPDpatients.

• Currently, the use of antibiotics is not indicatedin COPD, other than for treating infectiousexacerbations of COPD and other bacterialinfections.

•  All COPD patients with breathlessness when walking

at their own pace on level ground appear to benetfrom rehabilitation and maintenance of physicalactivity, improving their exercise tolerance and qualityof life, and reducing symptoms of dyspnea andfatigue.

Once COPD has been diagnosed, effective management

should be based on an individualized assessment of disease

in order to reduce both current symptoms and future risks

(%1234 (56). These goals should be reached with minimal

side effects from treatment, a particular challenge in COPD

patients because they commonly have comorbidities that

also need to be carefully identied and treated.

It is crucial for patients with COPD to understand the nature

of their disease, the risk factors for its progression, andtheir role and that of their health care workers in achieving

optimal management and health outcomes. The type of

health care workers seen, and the frequency of visits, will

depend on the health care system. Ongoing monitoring

should ensure that the goals of treatment are being met and

should include continuous evaluation of exposure to risk

factors and monitoring of disease progression, the effect of

treatment and possible adverse effects, exacerbation history,

and comorbidities. In addition, patients should receive

general advice on healthy living, including diet and the fact

that physical exercise is safe and encouraged for people with

COPD.

Identication and reduction of exposure to risk factors are

important in the treatment and prevention of COPD. Since

cigarette smoking is the most commonly encountered and

easily identiable risk factor, smoking cessation should be

encouraged for all individuals who smoke. Reduction of total

personal exposure to occupational dusts, fumes, and gases

and to indoor and outdoor air pollutants may be more difcult

but should be attempted.

Smoking cessation is the key intervention for all COPD

patients who continue to smoke (&GHI4DE4 #). Health careproviders are important to the delivery of smoking cessationmessages and interventions and should encourage allpatients who smoke to quit, even when patients visit a healthcare provider for reasons unrelated to COPD or breathingproblems.

,EEJK1BH>D13 &LK>?JA4?

 Although studies as yet have not been done to demonstratewhether interventions to reduce occupational exposuresalso reduce the burden of COPD, it seems common senseto advise patients to avoid continued exposures to potential

aggravants, if possible (&GHI4DE4 <).

Reducing the risk from indoor and outdoor air pollution isfeasible and requires a combination of public policy, localand national resources, cultural changes, and protectivesteps taken by individual patients. Reduction of exposureto smoke from biomass fuel, particularly among womenand children, is a crucial goal to reduce the prevalence ofCOPD worldwide. Efcient ventilation, non-polluting cookingstoves, use of ues, and similar interventions are feasibleand should be recommended37,30 (&GHI4DE4 :).

In previous versions of the GOLD report, COPD treatmentrecommendations were based on spirometry only. This is inkeeping with the fact that most of the clinical trial evidenceabout treatment efcacy in COPD is oriented around baseline

FEV$. However, FEV$ alone is a poor descriptor of diseasestatus and for this reason the treatment strategy for stableCOPD should also consider an individual patient’s symptomsand future risk of exacerbations. This individualizedassessment is summarized in %1234 (5M.

The guidance for clinical practice presented below isbased on evidence from clinical trials, as detailed in thediscussion of Evidence Levels at the beginning of thisdocument. However, it is important to recognize that allclinical trials recruit restricted groups of patients; this limits

their generalizability. In COPD the key inclusion criteria are:baseline FEV

$, acute bronchodilator reversibility, smoking

history, symptoms and a prior history of exacerbations. A fewgeneral considerations related to these inclusion criteria arediscussed below.

+0123452 )%6 78 The evidence for pharmacological treatment

of COPD is mostly based on the severity of airow limitation(FEV

$% predicted), and GOLD spirometry classication

has often been used as an entry criterion for clinical trials.There is almost no evidence on efcacy of COPD treatmentsin patients with FEV

$  70% predicted (GOLD 1), and no

evidence at all concerning anti-inammatory treatment

in patients with FEV$  0% predicted. Many studies ofcombination medications (inhaled corticosteroids pluslong-acting beta

"-agonists) have been limited to GOLD 3-4

(Severe-Very Severe airow limitation) patients. As no trialshave been carried out purely in GOLD 2 patients, evidenceof the efcacy of combination treatment in this group hasto be drawn from studies that included such patients as asubset of participants. Large studies such as TORCH$%& andUPLIFT214 each contained over 2,000 GOLD 2 patients, albeiin the lower stratum of GOLD 2 (FEV

$ < 0% predicted). In

general, it is important to draw a distinction between absenceof evidence that a treatment works and presence of evidencethat a treatment does not work.

 "9:;2 +<=59>=?430;=< @2A2<14B434;C8  Many COPD trialshave used low reversibility of airow limitation as an entrycriterion. Acute reversibility is not a reliable measurement31 

and, in general, acute reversibility in response tobronchodilator is a poor predictor of a treatment’s benet forFEV

$ after one year 32. Thus, this common clinical trial entry

criterion has limited impact on the reliability of therapeuticrecommendations.

%F092<B0;4=5 .<2A25;4=58  Studies in which exacerbations

entry criterion have also shown reductions in exacerbations,

even in patients with less severe airow limitation15,214. The

patient’s own history of exacerbations appears to be the

GOLD panel assumed that it is safe to extrapolate evidence

of efcacy from clinical trials to appropriate patients in routine

practice, regardless of the trial’s entry criteria concerning

previous exacerbation history.

*:BG$<=:E "503C1418 Results of clinical trials potentially

apply to every member of the intention-to-treat population,

whether they lie in the center of the distribution of severity or

at the extremes. Sub-group analysis, whether pre-specied

or not, must be used with caution. For example, if a treatment

has no effect in the intention-to-treat population, but appears

to have an effect that is conned to one sub-group, there is a

strong likelihood that one of the other groups would be worse

on the treatment. In contrast, subgroup analysis is useful

if it shows that a treatment effect is consistent in size and

direction across the range of patients recruited to the study.

In summary, sub-group analysis does not provide robust

evidence that a treatment works in a specic subgroup, butit can provide condence that the results from the intention-

to-treat population apply to patients who met the study entry

criteria. Subgroup analysis can also generate hypotheses to

be tested in subsequent trials.

Physical activity is recommended for all patients with COPD.

There is very little COPD-specic evidence to support

recommendations for physical activity other than studies of

pulmonary rehabilitation (the physical exercise component

is believed to provide the most benet). However, given the

overall population benets of physical exercise and its role inprimary and secondary prevention of cardiovascular disease,

it seems intuitively correct to recommend daily physical

activity.

 Although more information is needed on criteria for

patient selection for pulmonary rehabilitation programs, all

COPD patients appear to benet from rehabilitation and

maintenance of physical activity, improving their exercise

tolerance and experiencing decreased dyspnea and

fatigue33 (&GHI4DE4 #). Several studies have documented

an effect of pulmonary rehabilitation in patients with

breathlessness, usually mMRC 1, and following acute

exacerbations. Data suggest that these benets can be

sustained even after a single pulmonary rehabilitation

program341,34,35. Benet does wane after a rehabilitation

program ends, but if exercise training is maintained at home

the patient’s health status remains above pre-rehabilitation

Pharmacologic therapy in COPD is used to reduce

symptoms, reduce the frequency and severity of

exacerbations, and improve health status and exercise

tolerance. Existing medications for COPD have not been

conclusively shown to modify the long-term decline in lungfunction that is the hallmark of this disease12,15,175,17.

The classes of medications commonly used in treating

COPD are shown in %1234 S5S and a detailed description

of the effects of these medications is given in Chapter 3.

The choice within each class depends on the availability of

medication and the patient’s response. A proposed model for

initial pharmacological management of COPD according to

the individualized assessment of symptoms and exacerbation

risk is shown in %1234 (5(.

$<=:E " E0;425;1 have few symptoms and a low risk of

exacerbations. Specic evidence for the effectiveness ofpharmacologic treatments is not available for patients with

FEV$  0% predicted (GOLD 1). However, for all Group

 A patients, a short-acting bronchodilator used as needed

is recommended as rst choice based on its effect on lung

function and breathlessness&'&. An alternative choice

is a combination of short-acting bronchodilators or the

introduction of a long-acting bronchodilator. The evidence

for this step-up is weak; few studies of the combination

exist11,3, and most trials of therapy with long-acting

bronchodilators have been performed in patients with more

severe airow limitation212,37.

$<=:E + E0;425;1 have more signicant symptoms but still

a low risk of exacerbations. Long-acting bronchodilators are

superior to short-acting bronchodilators (taken as needed,

or prn) and are therefore recommended212,37. There

is no evidence to recommend one class of long-acting

bronchodilators over another for initial treatment. In the

individual patient, the choice should depend on the patient’s

perception of symptom relief. For patients with severe

breathlessness, the alternative choice is a combination of

long-acting bronchodilators237,23. Other possible treatments

include short-acting bronchodilators and theophylline, the

latter of which can be used if inhaled bronchodilators are

unavailable or unaffordable.

$<=:E - E0;425;1 have few symptoms but a high risk

of exacerbations. As rst choice a xed combination of

inhaled corticosteroid/long-acting beta"-agonist or a long-

acting anticholinergic is recommended15,212,214,240,244,251,3 .Unfortunately, there is only one study directly comparingthese treatments, which makes differentiation difcult3.

 As an alternative choice a combination of two long-actingbronchodilators or the combination of inhaled corticosteroid/

long-acting anticholinergic can be used. Both long-actinganticholinergic and long-acting beta

"-agonist reduce the

risk of exacerbations212,37, and although good long-termstudies are lacking, this principle of combination treatmentseems sound (although in many countries expensive).The recommendation for a combination of inhaledcorticosteroid/long-acting anticholinergic is not evidence-based, but this lack of evidence seems to be the result oflack of interest from the pharmaceutical industry ratherthan doubts about the rationale. A phosphodiesterase-4inhibitor used in combination with at least one long-actingbronchodilator could be considered if the patient has chronicbronchitis24,2. Other possible treatments include short-acting bronchodilators and theophylline if long-acting inhaledbronchodilators are unavailable or unaffordable.

$<=:E / E0;425;1 have many symptoms and a high riskof exacerbations. The rst choice of therapy is inhaledcorticosteroid plus long-acting beta

"-agonist or long-acting

anticholinergic, although there are conicting ndings

concerning this treatment"&(; support for it mainly comesfrom short-term studies257,53,53 (&GHI4DE4 :). As secondchoice a combination of all three classes of drugs (inhaledcorticosteroids/long-acting beta

"-agonist/long-acting

anticholinergic) is recommended"&'. It is also possible to adda phosphodiesterase-4 inhibitor to the treatment chosen asrst choice, provided the patient has chronic bronchitis"''.

 A phosphodiesterase-4 inhibitor is effective when addedto a long-acting bronchodilator 24, whereas evidence of itsbenet when added to inhaled corticosteroid comes fromless valid secondary analyses. Other possible treatmentsinclude short-acting bronchodilators, and theophyllineor carbocysteine"%' can be used if long-acting inhaled

bronchodilators are unavailable or unaffordable.

• There is no evidence to recommend a short-term

therapeutic trial with oral corticosteroids in patients with

COPD to identify those who will respond to inhaled

corticosteroids or other medications.• Long-term treatment with inhaled corticosteroids

is recommended for patients with severe and very

severe COPD and frequent exacerbations that are not

adequately controlled by long-acting bronchodilators

(&GHI4DE4 #).

• Long-term monotherapy with oral corticosteroids is not

recommended in COPD (&GHI4DE4 #).

• Long-term monotherapy with inhaled corticosteroids is

not recommended in COPD because it is less effective

than the combination of inhaled corticosteroids with long-

acting beta"-agonists (&GHI4DE4 #).

• Long-term treatment containing inhaled corticosteroids

should not be prescribed outside their indications, due tothe risk of pneumonia and the possibility of an increased

risk of fractures following long-term exposure540.

• The phosphodiesterase-4 inhibitor, roumilast, may also

be used to reduce exacerbations for patients with chronic

bronchitis, severe and very severe COPD, and frequent

exacerbations that are not adequately controlled by long-

acting bronchodilators (&GHI4DE4 :).

Routine follow-up is essential in COPD. Lung function

can be expected to worsen over time, even with the bestavailable care. Symptoms and objective measures of airowlimitation should be monitored to determine when to modifytherapy and to identify any complications that may develop.

 As at the initial assessment, follow-up visits should include adiscussion of symptoms, particularly any new or worseningsymptoms, and a physical examination. Comprehensiveself-management or routine monitoring does not appearto show long term benets in terms of quality of life or selfefcacy over usual care alone in COPD patients in generalpractice&''.

*n order to adjust therapy appropriately as the diseaseprogresses, each follow-up visit should include a discussionof the current therapeutic regimen. Dosages of variousmedications, adherence to the regimen, inhaler technique,effectiveness of the current regime at controlling symptoms,and side effects of treatment should be monitored.Treatment modications should be recommendedas appropriate with a focus on avoiding unnecessarypolypharmacy.

 At the individual patient level, measurements such as FEV$ 

and questionnaires such as the CAT are useful but are notcompletely reliable, because the size of a clinically importantresponse is smaller than between-assessment variability. Forthis reason, the following questions might be useful whendeciding whether a patient has had a symptomatic responseto treatment:

• Have you noticed a difference since starting this

treatment

• If you are better:

  Are you less breathless

  Can you do more

  Can you sleep better

  Describe what difference it has made to you.• Is that change worthwhile to you

Evaluate the frequency, severity, and likely causes ofany exacerbations!%$. Increased sputum volume, acutelyworsening dyspnea, and the presence of purulent sputumshould be noted. Specic inquiry into unscheduled visitsto providers, telephone calls for assistance, and use ofurgent or emergency care facilities is important. Severityof exacerbations can be estimated by the increased needfor bronchodilator medication or corticosteroids and by theneed for antibiotic treatment. Hospitalizations should be

documented, including the facility, duration of stay, and anyuse of critical care or mechanical ventilatory support.

Postoperative pulmonary complications are as importantand common as postoperative cardiac complications

and, consequently, are a key component of the increased

risk posed by surgery in COPD patients!%". The principal

potential factors contributing to the risk include smoking,

poor general health status, age, obesity, and COPD severity.

 A comprehensive denition of postoperative pulmonary

complications should include only major pulmonary

respiratory complications, namely lung infections, atelectasis

and/or increased airow limitation, which all potentially result

in acute respiratory failure and aggravation of underlying

COPD21,33-35.

Increased risk of postoperative pulmonary complicationsin COPD patients may vary with the severity of COPD,

although the surgical site is the most important predictor; risk

increases as the incision approaches the diaphragm34. Most

reports conclude that epidural or spinal anesthesia have a

lower risk than general anesthesia, although the results are

not totally uniform.

For lung resection, the individual patient’s risk factors should

be identied by careful history, physical examination, chest

radiography, and pulmonary function tests. Although the

value of pulmonary function tests remains contentious, there

is consensus that all COPD candidates for lung resection

should undergo a complete battery of tests, includingspirometry with bronchodilator response, static lung volumes,

diffusing capacity, and arterial blood gases at rest3,37.

COPD patients at high risk for surgical complications due

to poor lung function should undergo further lung function

assessment, for example, tests of regional distribution of

perfusion and exercise capacity3,37.

The risk of postoperative complications from lung resection

appears to be increased in patients with decreased predicted

postoperative pulmonary function (FEV$ or DL

CO < 30-40%

predicted) or exercise capacity (peak VO" < 10 ml/kg/min or

35% predicted). The nal decision to pursue surgery should

be made after discussion with the surgeon, pulmonary

specialist, primary clinician, and the patient. To prevent

postoperative pulmonary complications, stable COPD

patients clinically symptomatic and/or with limited exercise

capacity should be treated intensively before surgery, with

all the measures already well established for stable COPD

patients who are not about to have surgery. Surgery should

be postponed if an exacerbation is present.

features of COPD, such as systemic inammation, are

shared with other diseases and as such this mechanism

represents a link between COPD and some of its

increased by the sequelae of COPD; e.g., reduced physical

activity. Whether or not COPD and comorbid diseases

are related, management of the COPD patient must

include identication and treatment of its comorbidities.

Importantly, comorbidities with symptoms also associated

with COPD may be overlooked; e.g., heart failure and

lung cancer (breathlessness) or depression (fatigue

and reduced physical activity). Frequent and treatable

comorbidities should be prioritized.

example, in a patient with both COPD and heart failure an

exacerbation of COPD may be accompanied by worsening

Treatment of bronchiectasis in patients with COPD:

Treatment should be along conventional lines for

bronchiectasis with the addition of usual COPD strategies

where indicated. Whether prevention of exacerbations

requires more long-term use of oral or inhaled antibiotics

rather than bronchodilator or inhaled corticosteroid therapy

remains unknown.

Treatment of COPD in patients with bronchiectasis:  $%&'

should be treated as usual, although some patients may

need more aggressive and prolonged antibiotic therapy.

COPD is a common preventable and treatable disease, characterized by persistent airow limitation that is usu3

ally progressive and associated with enhanced chronic inammatory responses in the airways and the lungs to

noxious particles or gases. Exacerbations and comorbidities contribute to the overall severity in individual pa3

tients. GOLD 2014O)

 Asthma-COPD overlap syndrome (ACOS) is characterized by persistent airow limitation with several features

usually associated with asthma and several features usually associated with COPD. ACOS is therefore identied

by the features that it shares with both asthma and COPD.

vided there are no features that clearly make the diagnosis untenable. Clinicians are able to provide an estimate of their

level of certainty and factor it into their decision to treat. Doing so consciously may assist in the selection of treatment

and, where there is signicant doubt, it may direct therapy towards the safest option - namely, treatment for the condition

that should not be missed and left untreated.

Spirometry is essential for the assessment of patients with suspected chronic disease of the airways. It must be per 3

formed at either the initial or a subsequent visit, if possible before and after a trial of treatment. Early conrmation or

exclusion of the diagnosis may avoid needless trials of therapy, or delays in initiating other investigations. Spirometry

conrms chronic airow limitation but is of more limited value in distinguishing between asthma with xed airow obstruc3

tion, COPD and ACOS (Table 3).

Measurement of peak expiratory ow (PEF), although not an alternative to spirometry, if performed repeatedly on the

same meter over a period of 12 weeks may help to conrm the diagnosis of asthma by demonstrating excessive vari3

ability, but a normal PEF does not rule out either asthma or COPD. A high level of variability in lung function may also be

found in ACOS.

assessment must be reviewed and, if necessary, revised. As shown in Table 3, spirometry at a single visit is not always

conrmatory of a diagnosis, and results must be considered in the context of the clinical presentation, and whether

treatment has been commenced. Inhaled corticosteroids and long-acting bronchodilators inuence results, particularly

if a long withhold period is not used prior to performing spirometry. Further tests might therefore be necessary either to

conrm the diagnosis or to assess the response to initial and subsequent treatment.

Faced with a differential diagnosis equally balanced between asthma and COPD (i.e. ACOS) the default position should

be to start treatment accordingly for asthma (Table 4). This recognizes the pivotal role of ICS in preventing morbidity and

• If the syndromic assessment suggests asthma or ACOS, or there is signicant uncertainty about the diagnosis of

COPD, it is prudent to start treatment as for asthma until further investigation has been performed to conrm or

refute this initial position.

o Treatments will include an ICS (in a low or moderate dose, depending on level of symptoms).

o A long-acting beta2-agonist (LABA) should also be continued (if already prescribed), or added. However, it

is important that patients should not be treated with a LABA without an ICS (often called LABA monotherapy)

Referral for expert advice and further diagnostic evaluation is necessary in the following contexts:

• Patients with persistent symptoms and/or exacerbations despite treatment.

• Diagnostic uncertainty, especially if an alternative diagnosis (e.g. bronchiectasis, post-tuberculous scarring, bronchiol3

itis, pulmonary brosis, pulmonary hypertension, cardiovascular diseases and other causes of respiratory symptoms)

needs to be excluded.

• Patients with suspected asthma or COPD in whom atypical or additional symptoms or signs (e.g. haemoptysis, sig3

nicant weight loss, night sweats, fever, signs of bronchiectasis or other structural lung disease) suggest an additional

pulmonary diagnosis. This should prompt early referral, without necessarily waiting for a trial of treatment for asthma

or COPD.

• When chronic airways disease is suspected but syndromic features of both asthma and COPD are few.

• Patients with comorbidities that may interfere with the assessment and management of their airways disease.

• Referral may also be appropriate for issues arising during on-going management of asthma, COPD or ACOS, as out3

lined in the GINA and GOLD strategy reports.

Table 5 summarizes specialized investigations that may be used to distinguish asthma and COPD.
