Brief Summary:
The objective of this study is to evaluate the diagnostic accuracy of the GLORI-COPD score in ambulatory care, to enable the screening of COPD patients at risk of complications, requiring early management

Condition or disease
Pulmonary Disease, Chronic Obstructive

Detailed Description:
Chronic obstructive pulmonary disease (COPD) is a chronic disease with a high prevalence in France, but which remains under-diagnosed due to the trivialization of symptoms and difficulty in accessing diagnostic investigations. It is associated with other co-morbidities, with an impact on the occurrence of complications and quality of life. Early management of the most severe patients would allow better control of these risks of complications. Our objective is to better identify patients with COPD at risk of complications in general practice, taking into account the totality of the patient, to improve their management.

Official Title: Screening of COPD Patients at Risk of Complications in General Practice:

suspected COPD
Patients aged >35yo and > 10Pack.Year

Primary Outcome Measures :
  1. diagnostic accuracy of the score [ Time Frame: 12 months ]

    The diagnostic accuracy of the score will be evaluated to determine the risk of pulmonary complication in patients with COPD.

    Sensitivity, specificity, positive predictive value and negative predictive value

Secondary Outcome Measures :
  1. COPD diagnosis [ Time Frame: Baseline ]
    FEV1/FVC < 0.7

  2. complications [ Time Frame: 6 and 12 months ]
    -Composite criterion: Occurrence of a low respiratory infection (bronchitis, COPD exacerbation, lung infection or pneumonitis) in an outpatient or inpatient setting or following a death (1st event)

  3. death [ Time Frame: 12 months ]
  4. Modified Medical Research Council Dyspnea scale score (mMRC) [ Time Frame: baseline, 6 and 12 months ]
    evaluating dyspnea from 0 to 4: 0, no breathlessness except on strenuous exercise; 1, shortness of breath when hurrying on the level or walking up a slight hill; 2, walks slower than people of same age on the level because of breathlessness or has to stop to catch breath when walking at their own pace on the level; 3, stops for breath after walking ∼100 m or after few minutes on the level; and 4, too breathless to leave the house, or breathless when dressing or undressing

  5. COPD Assessment test (CAT) [ Time Frame: baseline, 6 and 12 months ]
    scores from 0-40. Higher scores denote a more severe impact of COPD on a patient's life

  6. ADO index (Age, Dyspnea, Obstruction) [ Time Frame: baseline, 6 and 12 months ]
    evaluates mortality risk in copd patients from 0 to 14 (higher scores are linked woh higher mortality risk)

  7. GOLD stage [ Time Frame: baseline ]
    COPD severity from A (less severe) to D (very severe)
