COPD

What to know

  • 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.

Definition details

Population
All adults.
Numerator
Adults who report having ever been told by a doctor, nurse, or other health professional they had chronic obstructive pulmonary disease (COPD), emphysema, or chronic bronchitis.
Denominator
All adults.
Measure
Prevalence (crude and age-adjusted).
Time Period of Case Definition
Lifetime.
Summary
In 2021, more than 15 million Americans (6.4%) reported that they have been diagnosed with COPD.¹ Major risk factors include tobacco smoking, occupational and environmental exposures, respiratory infections, and genetics.2 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.2
Notes
The indicator is based on being diagnosed by a physician and respondent recall of the diagnosis and may underestimate the true prevalence.

Population
All adults.
Numerator
Adults who report current smoking and having ever been told by a doctor, nurse, or other health professional they had chronic obstructive pulmonary disease (COPD), emphysema, or chronic bronchitis.
Denominator
Adults who report ever having physician-diagnosed COPD, emphysema, or chronic bronchitis.
Measure
Prevalence (crude and age-adjusted).
Time Period of Case Definition
Lifetime (COPD); current smoking.
Summary
In 2021, more than 15 million Americans (6.4%) reported that they have been diagnosed with COPD.¹ Among those diagnosed with COPD, 34.5% reported they were current smokers. ¹ Elimination of tobacco use or exposure may be the most effective way to reduce COPD because almost 80% of COPD deaths are attributable to smoking.2 Smoking cessation is key to the prevention and management of COPD.3
Notes
Because COPD is a chronic disease, years might pass before changes in behavior or clinical practice affect population prevalence.

Summary
In 2020, there were 247,314 (82.92 per 1,000 Medicare enrollees aged ≥ 65 years) hospitalizations with COPD as any diagnosis.1 In addition, COPD coexists with other conditions, including cardiovascular disease, diabetes, and other respiratory diseases such as pneumonia, that have high hospitalization rates.2 Risk factors for COPD-related hospitalization include patients with COPD who have a past history of similar events, severe airflow limitation, poor health status, increased age, presence of emphysema, leukocytosis,3 poor health-related quality of life and lack of regular physical activity.4 Disease-management programs, in addition to pharmacologic or surgical interventions, have been shown to reduce hospitalization among patients with severe COPD at risk for acute exacerbations of COPD.5
Notes
Multiple admissions for an individual patient can falsely elevate the number of persons with COPD. Medicare claims records cannot identify incident (new) hospitalizations for COPD.

Summary
In 2020, there were 165,248 (5.44 per 1,000 Medicare enrollees aged ≥ 65 years) hospitalizations with COPD as the first-listed diagnosis.1 Risk factors for hospitalization include patients with COPD who have a past history of similar events, severe of airflow limitation, poor health status, increased age, presence of emphysema, leukocytosis,2 poor health-related quality of life and lack of regular physical activity.3 Disease-management programs, in addition to pharmacologic and surgical interventions, have been shown to reduce hospitalization among patients with severe COPD at risk for acute exacerbations of COPD.4
Notes
Multiple admissions for an individual patient can falsely elevate the number of persons with COPD. Medicare claims records cannot identify incident (new) hospitalizations for COPD. Patients with COPD are often hospitalized with pneumonia and/or cardiovascular diseases, which may be the first-listed diagnosis.

Summary
Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the sixth leading cause of death in the United States in 2021.1 COPD is a progressive disease in which the body becomes less able to take in enough oxygen as airflow is obstructed;2 the obstruction of airflow is associated with increased mortality.3 Early diagnosis and effective management and treatment can help to reduce the risk of premature mortality.4,5
Notes
Because COPD is a chronic disease, years might pass before changes in behavior or clinical practice affect population mortality. Other comorbid conditions such as cardiovascular disease may displace COPD as the underlying cause of death that is reported on the death certificate.6,7

Summary
Chronic obstructive pulmonary disease (COPD) accounts for the majority of deaths from chronic lower respiratory diseases, the sixth leading cause of death in the United States in 2021.1 Because COPD often coexists with other diseases that may significantly influence patient outcomes,2 it is important to assess mortality from COPD as a contributing, as well as underlying, cause of death. COPD is a progressive disease in which the body becomes less able to take in enough oxygen as airflow is obstructed;3 the obstruction of airflow is associated with increased mortality.4 Early diagnosis and effective management and treatment of COPD and its comorbidities can help to reduce the risk of premature mortality.2,5,6
