Abstract
AIM:to determinate the correlation between scores obtained in the quality of life (QL) questionnaires with functional and clinical parameters.
METHODS:Prospective study. 56 moderate-severe COPD patients with exacerbating phenotype admitted from 1/02/11 to 30/10/11. Studied items: symptoms, MRC scale, spirometry, BMI, 6MWT, CAT and St.George. Descriptive analysis.
RESULTS: In Table 1 general characteristics are shown. Functional parametres do not correlate with CAT, and have a poor inverse correlation wiht St.George. BODE, 6 MWT and dyspnoea have a good correlation with both questionnaires. Graphic 1: correlation between BODE and SG, Graphic 2: correlation between CAT and SG, Graphic 3: correlation between scores obtained in CAT and SG about dyspnoea in basal situation.
CONCLUSIONS: CAT is a simple test with a good correlation with SG. CAT does not correlate with spirometric parameters but does with BODE and 6MWT. SG correlates slightly better than CAT with BODE.
