When to use
- Grading the severity of airflow limitation in a patient with spirometrically confirmed COPD.
Formula
With FEV1/FVC <0.70: GOLD 1 FEV1 >=80% predicted, GOLD 2 50-79%, GOLD 3 30-49%, GOLD 4 <30%.
Pearls and pitfalls
- The spirometric grade is only one axis; the full GOLD assessment also incorporates symptoms (mMRC/CAT) and exacerbation history (groups A-E).
- Airflow obstruction must first be confirmed by a post-bronchodilator FEV1/FVC <0.70.
