Screening for Chronic Obstructive Pulmonary Disease Using Spirometry: Summary of the Evidence for the U.S. Preventive Services Task Force

摘要

To support the USPSTF recommendation in this issue, Lin and colleagues reviewed the evidence on screening for COPD by using spirometry. Spirometry has not been shown to independently improve smoking cessation rates, and hundreds of patients would need to undergo spirometry to defer 1 COPD exacerbation. Potential harms from screening include false-positive results and adverse effects from subsequent unnecessary therapy.
