Methods EQ-5D SF-12 and SGRQ were obtained from COPD patients with GOLD stage III and IV hospitalized for an acute exacerbation both at admission and discharge. To assess the instruments properties utility values were calculated for EQ-5D and SF-12 and a total score was derived from the SGRQ. Results Mean utilities ranged from SF-12 stage IV to EQ-5D stage III at admission and from SF-12 stage IV to EQ-5D stage III at discharge. Completeness was best for EQ-5D and SGRQ while no utility value for the SF-12 could be calculated for more than 30 . For SGRQ subscales the minimal score occurred in up to 11 at admission while full health was observed for the EQ-5D at discharge in 13 . Sensitivity to change was generally good whereas discrimination between COPD stages was low for the EQ-5D. Conclusions Acute exacerbations seriously impair health status and quality of life. The EQ-5D is generally suitable to measure HrQoL in exacerbations of severe COPD although the high proportion of patients reporting full health at discharge poses a problem. The main issue with the SF-12 is the high proportion of missing values in a self-assessed setting. Properties of the SGRQ were satisfactory. However since no utility values can be derived from this diseasespecific instrument it is not suitable for cost-utility analyses in health-economic evaluations. Background Chronic .
