Model of Symptom/Risk Evaluation of COPD¹

When assessing risk, choose the highest risk according to GOLD grade or exacerbation history. One or more hospitalizations for COPD exacerbations should be considered high risk.
Patient Category	Characteristic	Spirometric Classification	Exacerbations Per year	CAT Score	mMRC Score
A	Low risk, less symptoms	GOLD 1–2	≤ 1	< 10	0–1
B	Low risk, more symptoms	GOLD 1–2	≤ 1	≥ 10	≥ 2
C	High risk, less symptoms	GOLD 3–4	≥ 2	< 10	0–1
D	High risk, more symptoms	GOLD 3–4	≥ 2	≥ 10	≥ 2

CAT = COPD Assessment Test; COPD = chronic obstructive pulmonary disease; GOLD = Global Initiative for Chronic Obstructive Lung Disease; mMRC = Modified Medical Research Council Dyspnea Scale
