debilitating disease with increasing mortality worldwide. The BODE index evaluates disease severity and the St George's Respiratory Questionnaire (SGRQ) measures health status. Objective: To identify the relationship between BODE index and the SGRQ and to test the predictive value of both tools against survival. Methods: Open cohort study of 1398 COPD patients (85% male) followed for up to 10 years. Measurements and main results: At the time of the inclusion, clinical data, forced spirometry and 6 min walking distance were determined and BODE index and SGRQ were calculated. Vital status and cause of death were documented at the end of follow-up. Results: The cohort's mean of FEV 1 % predicted was 46 AE 18%, BODE index was 3.6 AE 2.5, and SGRQ% total score was 49 AE 20. The SGRQ scores increased progressively as severity of COPD increased by BODE quartiles. The correlation between SGRQ and BODE index was good (r Z 0.58, p \u003c 0.0001). Both tests correlated with COPD survival (BODE Z À0.4 vs. SGRQ Z À0.20, p \u003c 0.0001). The area under the curve (AUC) for the BODE index was 0.77 vs. 0.66 for the SGRQ % total score (p \u003c 0.001).","publication_date":"2011,,","publication_name":"Respiratory

class="ds-related-work--abstract ds2-5-body-sm">Chronic obstructive pulmonary disease (COPD) is a highly prevalent disease. Currently, severity Global initiative for chronic Obstructive Lung Disease (GOLD) criteria are used to diagnose the severity of COPD, but a new grading system, the body mass index, bronchial obstruction, dyspnea, exercise (BODE) index, was recently proposed to provide useful prognostic information. The objective of this study is to evaluate the association between health-related quality of life (HRQOL) and COPD severity assessed by two criteria: the GOLD classification and the BODE index. Sixty-four patients with COPD were examined with lung function tests and specific and generic HRQOL questionnaires (St. George’s Respiratory Questionnaire [SGRQ], Nottingham Health Profile [NHP]). Participants were divided into four severity groups using the GOLD guidelines and the BODE index quartiles. The association between NHP and SGRQ subscales, and the BODE index was significant ( P &lt; 0.01). However, the GOLD class...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button"
