mMRC dyspnoea scale ranges from 0–4: Score 0–1 indicates breathlessness on exercise only, or on brisk walking Score 2 indicates person walks slowly or stops for breath (due to breathlessness) Score 3 indicates person stops for breath in less than 100 m walking Score 4 indicates person is breathless even while dressing Distance walked in 6 minutes, contributes 0–3 in the BODE index score. Patient is asked to walk for 6 minutes and his/her score is calculated as below: Score 0 indicates ≥350 m walking Score 1 indicates 250–349 m walking Score 2 indicates 150–249 m walking Score 3 indicates ≤149 m walking The spirometry (FEV1% pred.) contributes 0–3 in the BODE index score: Score 0 ≥65 FEV1% pred. (FEV1 is 65% or more of the predicted amount) Score 1 ≥50-64 FEV1% pred. (FEV1 is 50–64% of the predicted amount) Score 2 ≥36-49 FEV1% pred. (FEV1 is 36–49% of the predicted amount) Score 3 ≤35 FEV1% pred. (FEV1 is 35% or less of the predicted amount) Body mass index (relates height with weight), contributes 0–1 in the BODE index score Score 0 indicates BMI >21 Score 1 indicates BMI ≤21

Extracted from the doctors’ training module, developed as part of intervention.

6MWD = six-minute walk distance. BODE = Body mass index, airway Obstruction, Dyspnoea, Exercise capacity. BMI = body mass index. mMRC = modified Medical Research Council.
