Methodology · worked example, guidelines & full notes
Clinical takeaway

The spirometric grade (1–4) and the symptom/exacerbation group (A/B/E) are separate axes — pharmacotherapy is driven mainly by the ABE group, not by the FEV1 grade alone. (original synthesis · not guideline verbatim)

When to use

First confirm post-bronchodilator FEV1/FVC < 0.70, then enter FEV1 % predicted; the tool returns the GOLD grade. Combine the grade with the symptom/exacerbation ABE assessment to guide therapy.

How it works

Prerequisite: post-bronchodilator FEV1/FVC < 0.70. GOLD 1 ≥ 80% · GOLD 2 50–79% · GOLD 3 30–49% · GOLD 4 < 30% predicted.

Key points

  • The spirometric grade (1–4) and the symptom/exacerbation group (A/B/E) are separate axes — pharmacotherapy is driven mainly by the ABE group, not by the FEV1 grade alone. (original synthesis · not guideline verbatim)
  • The grade is valid only after a fixed post-bronchodilator FEV1/FVC < 0.70 confirms persistent airflow limitation; pre-bronchodilator values overdiagnose.
  • FEV1 correlates only modestly with symptoms and exacerbation risk, so it should not be the sole basis for treatment intensity.
