Spirometry testing in patients with COPD or those at high-risk for COPD (ages 50-74 years)
Individuals who had at least one spirometry (numerator), among Individuals aged 50-74 years diagnosed with COPD or defined at high-risk for COPD (denominator)
Rational:
COPD (Chronic Obstructive Pulmonary Disease) is a common respiratory disease characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities. According to WHO data, in 2015 COPD was the fourth leading cause of death worldwide [1]. Despite being the gold standard for the diagnosis and assessment of COPD, spirometry testing is underused. Earlier diagnosis using spirometry testing supports a treatment plan that may slow the progression of symptoms and decrease the number of exacerbations [2].
Numerator:
Individuals in the denominator who had at least one spirometry ever since 01/01/2011
Denominator
Individuals aged 50-74 years diagnosed with COPD or defined at high-risk for COPD ever since 01/01/2012
Notes:
Individuals diagnosed with COPD are defined by a new diagnosis of COPD, chronic bronchitis, pulmonary emphysema or chronic bronchiectasis or by purchasing COPD specific medications. Individuals at high risk for COPD are defined as persons with a history of tobacco smoking that were either diagnosed with asthma or purchased medications for chronic respiratory diseases.
