Why the study?
The association between the time of initial diagnosis and the severity of chronic obstructive pulmonary disease was investigated.
Is delayed initial diagnosis associated with greater disease severity in patients with COPD?
Is delayed initial diagnosis associated with greater disease severity in patients with COPD?
Delayed initial diagnosis of COPD is associated with worse lung function and greater disease severity.

May support earlier COPD diagnosis to limit severity; hypothesis-generating and requires prospective confirmation before practice change.
OBJECTIVE: To investigate the association of the time of initial diagnosis with the severity of chronic obstructive pulmonary disease (COPD). METHODS: A total of 803 patients who were diagnosed to have COPD for the first time in our hospital between May 2015 to February 2018 were enrolled in this study.The diagnoses of COPD and asthma COPD overlap (ACO) were made according GOLD guidelines and european consensus definition.Lung function of the patients was graded according to the GOLD guidelines. RESULTS: >0.05).A significant correlation was found between the disease course and the lung function of the patients.Multiple linear regression analysis showed that an older age and a longer disease course were associated with poorer lung functions and a greater disease severity. CONCLUSIONS: The delay of the initial diagnosis is significantly related to the severity of COPD.
