Abstract: There is evidence showing a tendency to upgrade COPD severity previously staged with spirometric-based GOLD (GOLD
1234) when using the new GOLD combined disease assessment (GOLD ABCD).

The aim of our study was to compare the GOLD
1234 classification in a population of stable COPD patients with the GOLD ABCD classification to determine whether
stable COPD was upgraded when using this new classification. After an observational study of a stable COPD cohort
(n=112), 61 patients (54.5%) had an increase in their COPD severity when moving from the old GOLD 1234 classification
to the current GOLD ABCD assessment (p<0.01). 42 patients (37.5%) had no change in severity of COPD. 9 patients COPD
were assessed to be better on using GOLD ABCD. This study highlights previously missed high-risk patients when
reviewing stable COPD. Continued incorporation of GOLD ABCD will translate into better evidence-based management.
