In almost any context, a “D” grade sounds bad. In their reassessment of screening for chronic obstructive pulmonary disease (COPD), the US Preventive Services Task Force (USPSTF) reaffirmed their recommendations from nearly a decade ago. That is, the USPSTF recommends against screening for COPD among asymptomatic adults because evidence of net benefit on outcomes is lacking.1 This lack of benefit from screening is discouraging to those who see screening as the best way to prevent the deleterious effects of COPD.
