• #1 Chronic Obstructive Pulmonary Disease (COPD): Practice Essentials, Background, Pathophysiology

  https://emedicine.medscape.com/article/297664-overview

  Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.23 million deaths in 2019. Tobacco smoking accounts for over 70% of COPD cases in high-income countries. In low- and middle-income countries, tobacco smoking accounts for only 30-40% of COPD cases, and household air pollution is a major risk factor. […] The formal diagnosis of COPD is made with spirometry; when the ratio of forced expiratory volume in 1 second over forced vital capacity (FEV1/FVC) is less than 70% of that predicted for a matched control, it is diagnostic for a significant obstructive defect. […] Criteria for assessing the severity of airflow obstruction (based on the percent predicted postbronchodilator FEV1) are as follows: Stage I (mild): FEV1 80% or greater of predicted; Stage II (moderate): FEV1 50-79% of predicted; Stage III (severe): FEV1 30-49% of predicted; Stage IV (very severe): FEV1 less than 30% of predicted or FEV1 less than 50% and chronic respiratory failure.

  https://www.cdc.gov/cdi/indicator-definitions/chronic-obstructive-pulmonary-disease.html

  Chronic obstructive pulmonary disease (COPD) is 1 of the top 10 causes of death in the United States. […] Nearly 16 million U.S. adults have COPD, and many more do not know they have it. […] COPD prevents airflow to the lungs, causing breathing problems. […] There is no cure for COPD, but it can be managed and treated. […] Public health professionals and others can help build awareness of COPD and support prevention, early diagnosis, treatment, and management strategies. […] In 2021, more than 15 million Americans (6.4%) reported that they have been diagnosed with COPD. […] Although there is no cure for COPD, it can be treated and managed to slow declining lung function, improve exercise tolerance, and prevent and treat exacerbations. […] The indicator is based on being diagnosed by a physician and respondent recall of the diagnosis and may underestimate the true prevalence.

  https://www.mayoclinic.org/diseases-conditions/copd/diagnosis-treatment/drc-20353685

  Often COPD can be hard to diagnose because symptoms can be the same as those of other lung conditions. Many people who have COPD may not be diagnosed until the disease is advanced. […] To diagnose your condition, your healthcare professional reviews your symptoms and asks about your family and medical history and any exposure you’ve had to lung irritants especially cigarette smoke. Your healthcare professional does a physical exam that includes listening to your lungs. You also may have some of these tests to diagnose your condition: pulmonary function tests, lab tests and imaging. […] Pulmonary function tests are done to find out how well your lungs are working. These tests may include: […] Spirometry. In this test, you breathe out quickly and forcefully through a tube connected to a machine. The machine measures how much air the lungs can hold and how quickly air moves in and out of the lungs. Spirometry diagnoses COPD and tells how much airflow is limited.

• #4 Diagnosis and early detection of COPD using spirometry

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4255165/

  The standard respiratory function test for case detection of chronic obstructive pulmonary disease (COPD) is spirometry. The criterion for diagnosis defined in guidelines is based on the FEV1/FVC ratio forced expiratory ratio (FER) and its severity is based on forced expiratory volume in one second (FEV1) from measurements obtained during maximal forced expiratory manoeuvres. […] However, COPD remains substantially under diagnosed in primary care and a major reason for this is underuse of spirometry. Early diagnosis is worthwhile, as it allows risk factors for COPD such as smoking to be addressed promptly and treatment optimised. […] As discussed previously, spirometry is accepted as the diagnostic test to assess airflow obstruction and classify severity of disease, based on specific cut points for FER (FEV1/FVC 0.7 after bronchodilator) and FEV1 (mild 80% predicted, moderate 50-80%, severe 30-49% predicted, very severe 30% predicted).

• #5 Chronic Obstructive Pulmonary Disease: Diagnosis and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2017/0401/p433.html

  The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing. […] COPD may be suspected based on findings from the history and physical examination, but must be confirmed by spirometry to detect airflow obstruction. […] Although COPD may be suspected based on findings from the history and physical examination, the diagnosis must be confirmed by spirometry to detect airflow obstruction and its severity. Spirometry is diagnostic for COPD when the postbronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio is less than 0.7. […] The ACP, GOLD, and NICE guidelines emphasize clinical suspicion of COPD based on history and physical examination findings, with confirmation by spirometry. […] Spirometry should be obtained to diagnose airflow obstruction in patients with respiratory symptoms. (Grade: strong.) Spirometry should not be used to screen for airflow obstruction in patients without respiratory symptoms. (Grade: strong.)

  Think of diagnosis of COPD in patients who are (1,2): 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 have no clinical features of asthma. […] When thinking about a diagnosis of COPD, ask the person if they have: weight loss, reduced exercise tolerance, waking at night with breathlessness, ankle swelling, fatigue, occupational hazards, chest pain, haemoptysis; these last 2 symptoms are uncommon in COPD and raise the possibility of alternative diagnoses. […] If COPD seems likely then perform post-bronchodilator spirometry to confirm the diagnosis (2): presence of a post bronchodilatory FEV1/FVC 0.7 confirms persistence of airflow obstruction and thus a diagnosis of COPD in patients with appropriate history and symptoms. […] Identifying airflow obstruction in COPD patients is critical in making the diagnosis: airflow obstruction is defined as (1): FEV1 80% predicted and FEV1/FVC 0.7. […] NICE suggests that post-bronchodilator spirometry should be measured to confirm the diagnosis of COPD (2).

• #7 COPD: clinical features and diagnosis – The Pharmaceutical Journal

  https://pharmaceutical-journal.com/article/ld/copd-clinical-features-and-diagnosis

  Chronic obstructive pulmonary disease (COPD) is a term used to describe a group of airways diseases that are not fully reversible. […] Diagnosis should take these symptoms into account, in addition to exposure to risk factors such as cigarette smoke. The severity of COPD can be assessed using spirometry. […] A diagnosis of COPD should be considered in patients over the age of 35 years who have a risk factor such as smoking and who display one or more of the symptoms described above. […] Airflow obstruction can be measured accurately using spirometry, and this should be performed at the time of diagnosis, with specific reference to the following measures: FEV1: volume of air that the patient is able to expel in the first second (expressed in litres and as a percentage of the predicted value).

  COPD is most often caused by long-term exposure to irritating smoke, fumes, dust or chemicals. The most common cause is cigarette smoke. […] Although COPD is a condition that can get worse over time, COPD is treatable. With proper management, most people with COPD can control symptoms and improve their quality of life. Proper management also can lower the risk of other conditions linked to COPD, such as heart disease and lung cancer. […] Talk with your doctor or other healthcare professional if your symptoms don’t get better with treatment or if symptoms get worse. Also talk with your healthcare professional if you notice symptoms of an infection, such as fever or a change in the mucus you cough up. […] The main cause of COPD in developed countries is tobacco smoking. In the developing world, COPD often occurs in people exposed to fumes from burning fuel for cooking and heating in homes that don’t have good airflow. Long-term exposure to chemical fumes, vapors and dusts in the workplace is another cause of COPD.

  See a GP if you have persistent symptoms of chronic obstructive pulmonary disease (COPD). […] To help them diagnose COPD, a GP may: ask you about your symptoms, examine your chest and listen to your breathing using a stethoscope, ask whether you smoke or used to smoke, calculate your body mass index (BMI) using your weight and height, ask if you have a family history of lung problems. […] They may also do, or arrange for you to have, a breathing test called spirometry, plus other related tests of the lungs and airways. […] A spirometry test can help show how well your lungs are working. […] The readings are compared with normal results for your age, which can show if your airways are obstructed. […] A chest X-ray can be used to look for problems in the lungs that can cause similar symptoms to COPD. […] A blood test can show other conditions that can cause similar symptoms to COPD, such as a low iron level (anaemia) and a high concentration of red blood cells in your blood (erythrocytosis). […] Sometimes more tests may be needed to confirm the diagnosis or determine the severity of your COPD.

• #11 Chronic Obstructive Pulmonary Diseases (COPD) | Overview

  https://www.nationaljewish.org/conditions/chronic-obstructive-pulmonary-disease/overview

  The most important and common diagnostic test for COPD is a breathing test. The name of that breathing test is spirometry, but it’s pretty simple. It requires you to take a deep breath in and blow it out as hard and fast as you can. With that test, we find out that the air passages are narrow and that’s sort of the classic definition of COPD along with symptoms. In addition, there’s some other tests that people sometimes have. They may go in and have a CAT scan of their chest because they have some other respiratory complaint and one finds emphysema on their chest x-ray. Breathing tests and x-rays are the most common ways we diagnose COPD. […] The first step in a COPD diagnosis is a thorough evaluation by an experienced doctor. A specialist who often sees people with COPD is a pulmonologist.

• #12 Diagnosis of Chronic Obstructive Pulmonary Disease | AAFP

  https://www.aafp.org/pubs/afp/issues/2008/0701/p87.html

  Chronic obstructive pulmonary disease affects more than 26 million adults in the United States. […] The diagnosis of chronic obstructive pulmonary disease is based on clinical suspicion and spirometry confirmation. […] A forced expiratory volume in one second/forced vital capacity ratio that is less than 70 percent, and that is incompletely reversible with the administration of an inhaled bronchodilator, suggests chronic obstructive pulmonary disease. […] Joint guidelines from the American Thoracic Society and the European Respiratory Society recommend a single quantitative test for alpha1-antitrypsin deficiency in patients diagnosed with chronic obstructive pulmonary disease who remain symptomatic despite bronchodilator therapy. […] The diagnosis of COPD is based on signs and symptoms and is confirmed by spirometry.

• #13 Diagnosis of Chronic Obstructive Pulmonary Disease | AAFP

• #16 Chronic obstructive pulmonary disease – Wikipedia

  https://en.wikipedia.org/wiki/Chronic_obstructive_pulmonary_disease

  Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. GOLD defines COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis, bronchiolitis) or alveoli (emphysema) that cause persistent, often progressive, airflow obstruction. […] The diagnosis is based on poor airflow as measured by spirometry. […] Spirometry measures the amount of airflow obstruction present and is generally carried out after the use of a bronchodilator, a medication to open up the airways. […] A FEV1/FVC ratio less than 70% in someone with symptoms of COPD defines a person as having the disease.

  The best predictor of frequent exacerbations (two or more per year) is a history of previously treated exacerbations. […] In addition, the risk of exacerbations is significantly higher in patients with airflow limitation 50% (severe or very severe COPD). […] The GOLD guideline uses a combined „ABE” approach to assess patients according to their level of symptoms and previous history of exacerbations. […] Detailed pulmonary function tests performed in specialist pulmonary function laboratories can measure flow volume loops and inspiratory capacity. […] Computed tomography (CT) scans show anatomic changes, and their use in COPD is increasing.

  COPD has an insidious onset and usually presents in older people. A history of productive cough, wheezing, and shortness of breath, particularly with exercise, is typical. […] Spirometry is required to make the diagnosis of COPD and is also used for monitoring disease progress. It is the most reproducible and objective measure of airflow limitation. Spirometry should be performed after administering an adequate dose of at least one short-acting inhaled bronchodilator to minimize variability. […] Chest x-ray (CXR) is rarely diagnostic but should be performed to exclude other diagnoses and to assess for the presence of significant comorbidities.

  To establish a diagnosis of COPD, clinical history should be used in conjunction with spirometry. Physicians should obtain a detailed clinical history that assesses patterns of symptom development, exacerbations, and multiple morbidities. […] A diagnosis of COPD should be confirmed using spirometry. In 1 study of 382 patients in 12 US family medicine practices, a clinical diagnosis of COPD or asthma made without spirometry was incorrect in up to 30% of cases. […] Airflow limitation that is not fully reversible, defined as a postbronchodilator ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) 0.70, indicates COPD.

  Recognising chronic obstructive pulmonary disease in primary care requires active case finding in symptomatic patients. Spirometry is essential for diagnosis. […] A diagnosis of COPD is made in a patient with typical symptoms (dyspnoea, cough, sputum) in whom spirometry demonstrates expiratory airflow obstruction that cannot be fully reversed by a bronchodilator. […] Screening of asymptomatic patients is not recommended; rather, early diagnosis in primary care relies on active case finding in symptomatic patients. […] A diagnosis of COPD requires spirometry demonstrating a reduced forced expiratory ratio (FER; forced expiratory volume in 1 second [FEV1] : forced vital capacity [FVC]). International guidelines define COPD as a postbronchodilator FER of less than 0.7. […] Spirometry is not only essential to the diagnosis of COPD, but provides a grading of COPD severity.

• #25 Diagnosis and early detection of COPD using spirometry

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4255165/

  The place of symptoms in the diagnostic criteria for COPD has been debated and there is some inconsistency between GOLD and NICE guidelines, with NICE advising not diagnosing COPD in the absence of symptoms in patients with mild airflow obstruction. […] Early diagnosis is a contentious issue, but it optimises the opportunities to prevent worsening of disease and prevention of comorbidities. […] Spirometry is a safe, practical and reproducible maximum breathing test that can be used in primary care to objectively determine the ventilatory capacity of the lungs. […] The standard respiratory function test for case detection of COPD is spirometry, with the criterion for diagnosis defined in guidelines being based on FER and the severity being based on FEV1. However, using this approach is poor at detecting early disease in the small airways.

  A chest X-ray may show some lung changes from COPD. An X-ray also can rule out other lung problems or heart failure. […] A CT scan combines X-ray images taken from different angles to create images of structures inside the body. A CT scan gives much greater detail of changes in your lungs than a chest X-ray does. A CT scan of your lungs can show emphysema and chronic bronchitis. A CT scan also can help tell if you might benefit from surgery for COPD. CT scans can be used to check for lung cancer. […] Pulmonary function and imaging tests also can be used to check your condition over time and see how treatments are working. […] Blood tests aren’t used to diagnose COPD, but they may be used to find the cause of your symptoms or rule out other conditions.

  COPD requires a diagnosis by a healthcare professional and ongoing assessments and monitoring throughout your lifetime. […] To diagnose COPD, which includes chronic bronchitis and emphysema, your healthcare provider will review your symptoms, ask for your complete health history, conduct a physical exam and look at test results. […] To diagnose COPD, your healthcare provider will use a pulmonary function test called spirometry. […] The most common lung function test is called spirometry. A spirometry test can diagnose COPD. A spirometer can measure the amount and speed of the air you blow out. This helps your healthcare provider see how well your lungs are working. […] People diagnosed with COPD, regardless of age or ethnicity, should be tested for AAT deficiency. Your healthcare provider may order a screening blood test to check the level of alpha-1 antitrypsin in your body.

  Chronic obstructive pulmonary disease affects more than 26 million adults in the United States. […] The diagnosis of chronic obstructive pulmonary disease is based on clinical suspicion and spirometry confirmation. […] A forced expiratory volume in one second/forced vital capacity ratio that is less than 70 percent, and that is incompletely reversible with the administration of an inhaled bronchodilator, suggests chronic obstructive pulmonary disease. […] Joint guidelines from the American Thoracic Society and the European Respiratory Society recommend a single quantitative test for alpha1-antitrypsin deficiency in patients diagnosed with chronic obstructive pulmonary disease who remain symptomatic despite bronchodilator therapy. […] The diagnosis of COPD is based on signs and symptoms and is confirmed by spirometry.

  After establishment of COPD diagnosis, further assessment is required to guide treatment. The goals of initial assessment of COPD are to determine the severity of airflow obstruction, impact of disease on patients health status, and risk of future events. […] Spirometry is one of the useful tools for pulmonary function test for COPD. It is readily available, non-invasive, reproducible and objective. During early stages of COPD when respiratory symptoms may be absent, spirometry can help identify COPD. […] Assessment of lung function by spirometry, particularly the post-bronchodilator FEV1, plays an important role in determining COPD severity and guiding treatment. A decline in FEV1 over time is indicative of disease progression. […] Other clinical assessments may be required in specific patients to characterize severity and guide management, make a differential diagnosis, identify comorbidities or underlying other abnormalities.

  Confirm all presumptive, symptom-based diagnoses of COPD one time with spirometry postbronchodilator ratio of FEV1/FVC 0.7. […] Diagnosis is based on a combination of medical history and physical examination and is confirmed through documentation of airflow limitation using spirometry. Confirmation with spirometry is important because COPD is over-diagnosed (59%) when patients are assessed by medical history alone. […] Although provincial access may be challenging, it is important to send all patients suspected of having COPD for one-time confirmation of the diagnosis by spirometry. […] Neither chest x-ray nor CT is required for diagnosing COPD. CT may be helpful to screen for lung cancer in appropriate patients. […] Once the diagnosis is confirmed by spirometry, determine the level of COPD severity with a tool such as the modified Medical Research Council (mMRC) Dyspnea Scale or the COPD Assessment Test (CAT).

  Chronic Obstructive Pulmonary Disease (COPD) is typically suspected in patients with symptoms like dyspnea, chronic cough, or sputum production. Accurate diagnosis is crucial for effective management, with spirometry being essential for confirmation. […] COPD diagnosis is suspected in a patient with symptoms of dyspnea, chronic cough, or sputum production. Key clinical indicators that increase the probability of a COPD diagnosis are progressive persistent dyspnea, worsening with exercise, recurrent wheezing, chronic cough, recurrent lower respiratory infections and a history of risk factors. However, spirometry is required to establish COPD diagnosis. […] COPD needs to be accurately diagnosed for optimal management. Therefore, differential diagnoses, such as asthma, congestive heart failure, bronchiectasis, tuberculosis, obliterative bronchiolitis, and diffuse panbronchiolitis, should be considered to make a clear distinction from COPD.

  The place of symptoms in the diagnostic criteria for COPD has been debated and there is some inconsistency between GOLD and NICE guidelines, with NICE advising not diagnosing COPD in the absence of symptoms in patients with mild airflow obstruction. […] Early diagnosis is a contentious issue, but it optimises the opportunities to prevent worsening of disease and prevention of comorbidities. […] Spirometry is a safe, practical and reproducible maximum breathing test that can be used in primary care to objectively determine the ventilatory capacity of the lungs. […] The standard respiratory function test for case detection of COPD is spirometry, with the criterion for diagnosis defined in guidelines being based on FER and the severity being based on FEV1. However, using this approach is poor at detecting early disease in the small airways.

  The severity of airflow obstruction correlates weakly with symptom severity and impairment in health status. Therefore, changes in FEV1 are unable to capture the impact of COPD on patients health in its entirety. Short patient-centered questionnaires are the most efficient and accurate tools to assess severity of symptoms, limitation in activities of daily living and health-related quality of life (HRQoL). […] The implementation of quick and easy-to-use questionnaires in routine clinical practice can enable physicians fully comprehend the HRQoL of their patients, improve transparency, and prescription of appropriate treatment and effective COPD monitoring. […] In case of a substantial gap between perceived symptoms and severity of airflow obstruction, a better understanding of the lung physiology is required, which may require additional assessments. Thus, in patients with persistent symptoms after initial treatment, additional clinical assessment, including measurement of lung volumes, diffusion capacity, exercise testing and/or lung imaging may be considered.
