[Spotting the GLObalRIsk of severe outcomes in undiagnosed COPD patients (GLORI-COPD)]

Chronic obstructive pulmonary disease (COPD) is a severe chronic disease and its prevalence is increasing. Nevertheless, mortality linked to moderate and mild COPD without comorbidities is low. The aim of the study is to create and validate a questionnaire in primary care to spot patients with undiagnosed COPD who are at high risk of severe complications considering the severity of their COPD and their comorbidities.

The development of the questionnaire has three steps. The first is the selection of the items which can be included in the questionnaire with a two-round Delphi method. The second step is a cross-sectional study to assess the link between spirometry and the selected items in the first step. The last step is the validation of the questionnaire in a prospective study in primary care.

Identifying undiagnosed COPD patients with a high global risk of complications in primary care will help to establish which patients have to be diagnosed as a priority. This is particularly useful in general practice as the patient is considered globally and not just on the basis of respiratory criteria. It should allow better selection of patients who need specialised follow up.
