In chronic obstructive pulmonary disease (COPD<\/jats:styled-content>) patients, the CAT<\/jats:styled-content> improves with pulmonary rehabilitation (PR<\/jats:styled-content>), and changes correlate with improvements in longer\u2010established health status instruments such as the C<\/jats:styled-content>hronic R<\/jats:styled-content>espiratory Q<\/jats:styled-content>uestionnaire (CRQ<\/jats:styled-content>). Increasing numbers of non\u2010COPD<\/jats:styled-content> patients are referred for PR<\/jats:styled-content>, but it is not known whether the CAT<\/jats:styled-content> is responsive to PR<\/jats:styled-content> in these populations.<\/jats:p><\/jats:sec>Methods<\/jats:title>The CAT<\/jats:styled-content> score was prospectively measured in 365 consecutive patients (255 COPD<\/jats:styled-content>, 110 non\u2010COPD<\/jats:styled-content>) before and after an 8\u2010week PR<\/jats:styled-content> programme. Pre to post change in CAT<\/jats:styled-content> was calculated for COPD<\/jats:styled-content> and non\u2010COPD<\/jats:styled-content> patients, and correlated with change in the CRQ<\/jats:styled-content>.<\/jats:p><\/jats:sec>Results<\/jats:title>For both non\u2010COPD<\/jats:styled-content> and COPD<\/jats:styled-content> patients, there was a similar and significant improvement in the mean (95% confidence interval) CAT<\/jats:styled-content> score following PR<\/jats:styled-content> (non\u2010COPD<\/jats:styled-content>: \u22122.1 (\u22121.0, \u22123.2) vs COPD<\/jats:styled-content>: \u22123.0 (\u22122.2, \u22123.8); P<\/jats:styled-content><\/jats:italic>\u2009=\u20090.19).
