- The 2011 COPD Update [1] defines four risk categories for COPD patients (A to D) depending upon: i) symptoms (modified dyspnea score from th Medical Research Council, mMRC) or CAT questionnaire; ii) spirometric classification: GOLD I: FEV1 ≥ 80% pred; GOLD II: 50% ≤ FEV1 < 80% pred; GOLD III: 30% ≤ FEV1 < 50% pred; and, GOLD IV: FEV1 < 30% and/or PaO2 < 60 mmHg breathing FIO2 0.21); and, iii) frequency of exacerbations per year. Recent reports have assessed the predictive value of this classification [16, 17]
