Updated GOLD guidance includes new guidance on vaccination, diffusing capacity of the lungs for carbon monoxide (DLCO) testing, and lung cancer screening

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has released the 2022 version of its comprehensive report on the diagnosis, management, and prevention of COPD. Updated information includes:

  • Use of DLCO testing for diagnosis in the field

  • A systematic review showing that, compared with placebo, pharmacological treatment for COPD can reduce the rate of decline in FEV1 by 5.0 mL/year

  • Updated vaccination recommendations from the US Centers for Disease Control and Prevention (CDC): coronavirus disease 2019 (COVID-19) vaccine for all people with COPD, and varicella-zoster (shingles) vaccine for those aged ≥50 years

  • A recommendation for annual low-dose CT scanning for lung cancer in patients with COPD due to smoking (in line with US Preventive Services Task Force recommendations).
