COPD: The statistics
- 14.5% or one in seven Australians 40 years or over have airflow limitation of their lungs. 1
- This figure increases to 29.2% in Australians 75 years or over. 1
- 7.5% of Australians 40 or over have COPD that has progressed sufficiently to where symptoms may already be present and affecting daily life. Half of these people will not know they have it.1
- COPD is the second leading cause of avoidable hospital admissions.2
- Despite falling death rates, COPD is still a leading cause of death and disease burden after heart disease, stroke and cancer.3
- Currently, there is no cure for COPD, there are things people can do to breathe easier, keep out of hospital and improve their quality of life.4
- COPD is preventable and treatable.4
What is COPD?
- Chronic Obstructive Pulmonary Disease (COPD) is a long-term disease of the lungs which causes shortness of breath. While COPD currently has no cure, there are things that people can do to breathe easier, keep out of hospital and improve their quality of life.4
- COPD is an umbrella term that includes emphysema, chronic bronchitis and chronic asthma which isn’t fully reversible.
- COPD is usually characterised by:
- Shortness of breath
- A repetitive cough with phlegm / mucus most days
- History of cigarette smoking or exposure to other environmental pollutants (smokes and fumes) or industrial dust
How does a person with COPD feel?
Symptoms for an individual with COPD tend to creep up gradually. Breathlessness may lead those with the condition to cut back on physical activities. This gradual decline continues until simple daily activities like showering, dressing or making a cup of tea, become almost impossible. Depression and anxiety often affect those with COPD.
What Causes COPD?
- In the western world, cigarette smoking is the single largest cause of COPD.4 However, despite being the highest risk group for COPD, regular smokers are less likely than the rest of the population to consider themselves at risk of developing COPD.5
- Some 20% of COPD occurs in never smokers6.
- Other known risk factors are passive smoking, especially during infancy when the lungs are still developing, exposure to environmental agents, including indoor and outdoor air pollutants and occupational dusts and chemicals.4
- Women may be at greater risk than men of COPD from exposures at work and are more susceptible to COPD due to smaller lungs and airways and more sensitive airways.7
- Chronic asthma may evolve into COPD in later life, especially in those who have smoked and when appropriate medications have not been taken properly.4
Prevalence of COPD
- Lung Foundation Australia estimates that approximately over 1.45 million Australians have some form of COPD.8 This represents approximately one in seven Australians over 40.1
- Of those with COPD currently, Lung Foundation Australia estimates that over 750,000 Australians1,8 have COPD that has progressed to a stage at which symptoms, such as breathlessness may already be present and affecting their daily lives. Half of these people do not have a doctor’s diagnosis of COPD and are therefore not taking the important steps to slow down the progression of the disease.1
- Nearly 700,000 Australians1,8 have a mild form of COPD where symptoms may not yet be present. Many of these will go on to develop more severe COPD.
- People who unknowingly have COPD may mistake their symptoms as signs of ageing, lack of fitness or asthma – a simple lung function test called spirometry from a GP can diagnose COPD.
The Burden of COPD
- In Australia, despite falling death rates, COPD is still a leading cause of death and disease burden after heart disease, stroke and cancer3.
- COPD is a significant cause of death in Australia.
- COPD is the second leading cause of avoidable hospital admissions in Australia.2
- In 2008, the total economic impact of COPD was estimated to be $98.2 billion of which $8.8 billion was attributed to financial costs and $89.4 billion to the loss of wellbeing.10
- Of the financial costs ($8.8 billion), a large proportion is due to the loss of productivity due to COPD, ie lower employment, absenteeism and the workplace impact of premature death of Australians with COPD.10
- The direct cost to the Australian health care system is estimated to be $900 million with hospital use contributing the largest share of health spending ($473 million).10
- In addition to the above costs on the public and private sector purse, there are the costs that are harder to quantify – those of lost wellbeing as a result of COPD. These are estimated to be some $90 billion.10
- In terms of overall costs, COPD is more costly per case than cardiovascular disease, osteoporosis or arthritis.10
COPD diagnosis and treatment
- COPD is preventable and treatable4.
- While there is no cure for COPD, there is strong medical evidence to show that early diagnosis, combined with disease management programs at the early stages of the disease could reduce the burden of COPD, improving quality of life, slowing disease progression, reducing mortality and keeping people out of hospital.4
- Lower costs and burden of disease can result if diagnosis is achieved early and optimally assessed, especially as treatment can reduce exacerbations. 13-18
The key aims of COPD treatment are to reduce symptoms, improve quality of life, increase the capacity for exercise and ultimately, keep people well and out of hospital. There are a number of steps people with COPD can take to breathe easier and improve their quality of life.
- Stop smoking – helps improve symptoms and slow down the rate the disease progresses.4,14
- Inhaled medicines – reduce symptoms, improve quality of life, reduce activity limitation and prevent exacerbations associated with hospital admissions. Check inhaler device regularly. 4
- Pulmonary rehabilitation –reduces breathlessness, fatigue, anxiety and depression, improves exercise capacity, emotional function and health-related quality of life and enhances patients’ sense of control over their condition. Pulmonary rehabilitation reduces hospitalisation and has been shown to be cost-effective.4
- Regular immunisations against influenza and pneumonia.4
- Support groups/services – as COPD worsens and patients feel less able to carry on their normal activities, patients become increasingly isolated. Support groups/services can help meet the emotional and social needs of people with the condition, helping them realise that they are not alone.
- Oxygen therapy – helps those people with advanced lung disease who are unable to absorb sufficient oxygen to supply their vital organs.4
- People older than 35 with a history of cigarette smoking should speak with their GP if they do any of the following:
- Cough several times most days
- Bring up phlegm or mucus most days
- Are short of breath compared with others their age
