Epidemiology
• About 3 million people have chronic obstructive pulmonary disease (COPD) in the UK
• Nearly 900,000 people in England and Wales are diagnosed as having COPD and an estimated 2 million people have COPD which remains undiagnosed
• Symptoms usually develop insidiously making it difficult to determine the true prevalence of the disease
• Most patients are not diagnosed until they are in their fifties
Background
• COPD is predominantly caused by smoking and is characterised by airflow obstruction that:
- is not fully reversible- does not change markedly over several months- is usually progressive in the long term
• Exacerbations often occur, where there is a rapid and sustained worsening of symptoms beyond normal day-to-day variations requiring a change in treatment
ScopeThe scope for the guideline update was to examine:
a) Diagnosis and severity classification:
•spirometry and post-bronchodilator values
•multidimensional severity assessment indices (for example, the BODE index)
b) Management of stable COPD and prevention of disease progression
•long-acting bronchodilators: beta2 agonists and anticholinergics (tiotropium, formoterol fumarate, salmeterol) as monotherapy and in combination, both with and without inhaled corticosteroids
•mucolytic therapy (carbocisteine and mecysteine hydrochloride)
BODE = body mass index, airflow obstruction, dyspnoea and exercise tolerance
Definition of COPD
• Airflow obstruction is defined as reduced FEV1/FVC ratio (< 0.7)
• It is no longer necessary to have an FEV1 < 80% predicted for definition of airflow obstruction
• If FEV1 is ≥ 80% predicted, a diagnosis of COPD should only be made in the presence of respiratory symptoms, for example breathlessness or cough
• COPD produces symptoms, disability and impaired quality of life which may respond to pharmacological and other therapies that have limited or no impact on the airflow obstruction.
FEV1 = forced expiratory volume in 1 secondFVC = forced vital capacity
Natural History
•The Fletcher-Peto Diagram, illustrating the effects of smoking on rate of decline in FEV1
Diagnose COPD
Consider a diagnosis of COPD for people who are:• over 35, and• smokers or ex-smokers, and• have any of these symptoms:
- exertional breathlessness- chronic cough- regular sputum production,- frequent winter ‘bronchitis’ - Wheeze
• And no clinical features of asthma
[2004]
Diagnose COPD: Spirometry• Perform spirometry if COPD seems likely [2004]
• The presence of airflow obstruction should be confirmed by performing post-bronchodilator spirometry [new 2010]
• Consider alternative diagnoses or investigations in: - older people without typical symptoms of COPD where the FEV1/FVC ratio is < 0.7- younger people with symptoms of COPD where
the FEV1/FVC ratio is ≥ 0.7 [new 2010]
• All health professionals involved in the care of people with COPD should have access to spirometry and be competent in the interpretation of the results [2004]
Differentiating COPD from asthma
Clinical features COPD Asthma
Smoker or ex-smoker Nearly all Possibly
Symptoms under age 35 Rare Often
Chronic productive cough Common Uncommon
Breathlessness Persistent and progressive
Variable
Night time waking with breathlessness and or wheeze
Uncommon Common
Significant diurnal or day to day variability of symptoms
uncommon Common
[2004]
Differentiating COPD from asthma: 2
• If diagnostic uncertainty remains, the following findings should be used to help identify asthma:
- FEV1 and FEV1/FVC ratio return to normal with drug therapy
- a very large (>400ml) FEV1 response to bronchodilators or to 30mg prednisolone daily for 2 weeks
- serial peak flow measuremenst showing significant (20% or greater) diurnal or day-to-day variability
- remaining diagnostic uncertainty may be resolved by referral for more detailed investigations
[2004]
Diagnose COPD: assessment of severity
• Assess severity of airflow obstruction using reduction in FEV1

Managing stable COPD
Assess symptoms/problemsManage those that are present as below
Patients with COPD should have access to the wide range of skills available from a multidisciplinary team
Managing stable COPD: Stop smoking
• Encouraging patients with COPD to stop smoking is one of the most important components of their management
• All COPD patients still smoking, regardless of age, should be encouraged to stop, and offered help to do so, at every opportunity
• Record a smoking history, including pack years smoked
• Offer nicotine replacement therapy, varenicline or bupropion (unless contraindicated) combined with a support programme to optimise quit rates [2010]
[2004]
Managing stable COPD: Promote effective inhaled
therapyIn people with stable COPD who remain breathless or have exacerbations despite using short-acting bronchodilators as required, offer the following as maintenance therapy:
•if FEV1 ≥ 50% predicted: either LABA or LAMA
•if FEV1 < 50% predicted: either LABA+ICS in a combination inhaler, or LAMA
Offer LAMA in addition to LABA+ICS to people with COPD who remain breathless or have exacerbations despite taking LABA+ICS,irrespective of their FEV1
ICS = inhaled corticosteroidLABA = long-acting beta2 agonist
LAMA = long-acting muscarinic agonist[new 2010]
Managing stable COPD: inhaled therapies

Managing stable COPD: Oral corticosteroids
• Maintenance use of oral corticosteroid therapy in COPD is not recommended
• Some patients with advanced COPD may require maintenance oral corticosteroids when these cannot be withdrawn following an exacerbation
• The does of oral corticosteroids should be kept as low as possible
• Any patient treated with long term corticosteroid therapy should be monitored for the development of osteoporosis and given appropriate prophylaxis. Patients over the age of 65 should be started on prophylactic treatment without the need for monitoring
Managing stable COPD: Oxygen
• Clinicians should be aware that inappropriate oxygen therapy inpeople with COPD may cause respiratory depression
• Use appropriate oxygen therapy:
• Long-term oxygen therapy• Ambulatory• Short burst
Managing stable COPD: Cor pulmonale
• A diagnosis of cor pulmonale should be considered if patients have:
- Peripheral odema, raised venous pressure, systolic parasternal heave, a loud pulmonary second heart sound.
• Assess need for oxygen
•Use diuretics
[2004]
Managing stable COPD: provide pulmonary
rehabilitation
Pulmonary rehabilitation
An individually tailored multidisciplinary programme of care to optimise patients’ physical and social performance and autonomy
Tailor multi-component, multidisciplinary interventions to individual patient’s needs
Hold at times that suit patients, and in buildings with good access
Offer to all patients who consider themselves functionally disabled by COPD
Make available to all appropriate people, including those recently hospitalised for an acute exacerbation
[new 2010]
Multidisciplinary working
• COPD care should be delivered by a multidisciplinary team that includes respiratory nurse specialists
• Consider referral to specialist departments (not just respiratory physicians)
[2004]
Specialist department Who might benefit?Physiotherapy Advice about excessive sputum
Dietetic advice People with BMI that is high, low or changing over time
Occupational therapy People needing help with daily living activities
Social services People disabled by COPD
Multidisciplinary palliative care teams
People with end-stage COPD (and their families and carers)
Follow-up of patients with COPD
• Follow-up of patients should include:
-Highlighting the diagnosis in the case record
-Recording the values of spirometric tests
-Offering stop smoking advice
-Recording the opportunistic measurement of spirometric parameters
• Patients should be reviewed at least once per year
• For most patients with stable severe disease regular hospital review is not necessary[2004]
Managing exacerbations• Minimise impact of exacerbations by:
- giving self-management advice on responding promptly to symptoms of exacerbation
- starting appropriate treatment with oral steroids and/or antibiotics
- use of non-invasive ventilation when indicated
- use of hospital-at-home or assisted-discharge schemes
• The frequency of exacerbations should be reduced by appropriate use of inhaled corticosteroids and bronchodilators, and vaccinations
[2004]
Use non-invasive ventilation (NIV)
• Use NIV as the treatment of choice for persistent hypercapnic ventilatory failure during exacerbations not responding to medical therapy
• NIV should be delivered by staff trained in its application, experienced in its use and aware of its limitations
• When starting NIV, make a clear plan covering what to do in the event of deterioration and agree ceilings of therapy
[2004]
Palliative care
• Palliative care depends on good understanding of patients’:- Perception of their quality of life- Satisfaction with current functioning- Expectations
• Opioids, benzodiazepines, tricyclic antidepressants, major tranquilisers and oxygen can be used for the palliation of breathlessness in patients with end stage COPD unresponsive to other medical therapy
• Providers of care should adopt an effective and equitable standardised approach to palliative care such as that provided by the Liverpool care pathway or equivalent
[2004]
Costs per 100,000 population
Costs are based on recommendations which have the most significant resource impact: 1.2.2.5 - 1.2.2.9
Costs per annum£
Current cost of prescribing 524,291
Future cost of prescribing 624,812
Incremental cost of prescribing 100,521
Estimated 5% reductions in hospital admissions 30,302
Estimated cost of implementation 70,219
Discussion
• How can we improve identification and diagnosis of people over 35 who have a risk factor?
• How does our use of spirometry compare with the recommendations?
• How will our prescribing practice need to change?
• What pulmonary rehabilitation services are available?
• How do we minimise the risk of exacerbations for our patients?
