Canadian Thoracic Society releases new guidelines for treatment of COPD
Toronto, ON September 21, 2007 – The Canadian Thoracic Society (CTS) today released new guidelines for the treatment of chronic obstructive pulmonary disease (COPD). The “Canadian Thoracic Society recommendations for management of chronic obstructive pulmonary disease – 2007” are based upon the latest evidence and provide physicians with the most up-to-date information for treating this debilitating disease.
COPD is a progressive lung disease which includes chronic bronchitis and emphysema. More than 714,000 Canadians have been diagnosed with COPD and there are estimated to be thousands more who have not yet been diagnosed [ref]. In 2007 alone, approximately 9,000 Canadians will die from COPD [ref] and the incidence of the disease is steadily increasing. It is predicted that by 2020 COPD will be the third leading cause of death worldwide [ref].
“Recently, the number and size of randomized clinical trials in the area of COPD have increased dramatically,” says Dr. Paul Hernandez, a member of the CTS COPD Guidelines Development Committee and Associate professor of Medicine at Dalhousie University. “Major studies like TORCH and OPTIMAL have provided us with a wealth of new evidence on which to base these treatment recommendations and reinforce that COPD is a treatable, preventable and under-diagnosed disease.”
Changes to the guidelines
Two of the most significant areas addressed by the 2007 guidelines are the prevention and management of exacerbations and new algorithms to ensure patients are receiving adequate therapy appropriate to their disease severity.
Exacerbations or worsening of symptoms can be triggered by simple occurrences such as a common cold, change in weather, or allergies. They can often result in visits to the local Emergency Department, hospitalization and, in severe cases, can lead to death.
“It’s vital that physicians recognize the importance of exacerbations in the life of a patient with COPD, “says Hernandez. “COPD is not just a nuisance disease that people live with, but a serious disease that people die from. We should consider exacerbations in COPD patients as important as myocardial infarction in people with ischemic heart disease. We need to not only prevent the first exacerbation, but work more proactively to prevent all subsequent flare ups of the disease.”
New treatment algorithms outline optimal pharmacological and non-pharmacological management for COPD according to disease severity. With appropriate treatment, patients with COPD should expect to experience less shortness of breath, better exercise tolerance, fewer hospitalizations and improved quality of life.
Other key areas addressed in the 2007 guidelines include:
New information regarding the epidemiology of COPD based on the Burden of COPD in Canada survey.
Rates of COPD prevalence have been underestimated and are continuing to increase, particularly among women. COPD is now the fourth leading cause of death in Canada.
The link between COPD and co-morbidities.
There is now evidence to associate COPD with co-morbid diseases, including CVD, cancer, osteoporosis, glaucoma, cataracts, depression and malnutrition.
Classification of disease severity.
The revised guidelines address the measurement of airflow through spirometry to be more aligned with international guidelines, while still recognizing the importance of symptoms as measures of functional disability.
Regional disparity in access to pulmonary rehabilitation programs, patient education and coverage for medications.
Implications of 2007 guidelines for clinical practice
The 2007 guidelines emphasize the importance of spirometry as not just a diagnostic tool for COPD, but to determine which patients will benefit most from specific pharmacological interventions.
“The important take-away message for physicians from the revised guidelines is that this is a treatable disease, and with the right treatment options available, patients can do better,” says Dr. Denis O’Donnell, a Chair of the CTS COPD Guidelines Development Committee and Professor of Medicine and Physiology, Queen’s University. “Through early diagnosis and correct assessment of disease severity through spirometry testing, along with early and aggressive treatment with both lifestyle changes and medications, COPD can be managed and patients can maintain an improved quality of life.”
