Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>PURPOSE:</title> <p>The COPD Assessment Tool (CAT) has previously been shown to be a sensitive outcome measure for pulmonary rehabilitation (PR) in a stable population, but its utility in a postexacerbation PR population is unknown. The aim of this study was to investigate any differences in response to the CAT between stable and postexacerbation patients undertaking PR.</p> </sec> <sec> <title>METHODS:</title> <p>Patients attending a 7-week outpatient PR program completed a CAT questionnaire pre- and postrehabilitation. Patients referred for elective outpatient PR were compared with those who had been referred to PR following a hospital admission for an exacerbation.</p> </sec> <sec> <title>RESULTS:</title> <p>Two hundred consecutive patients completed the CAT questionnaire: 125 stable patients (74 male, mean age 71.1 ± 8.9 years, forced expiratory volume in 1 second [FEV<sub>1</sub>] 1.39 L ± 0.6, and body mass index [BMI] 28.5 ± 6.7 kg/m<sup>2</sup>) and 75 postexacerbation patients (23 male, mean age 70.6 ± 8.6 years, FEV<sub>1</sub> 1.16 L ± 0.5, and BMI 25.8 ± 7.3 kg/m<sup>2</sup>). A statistically significant difference between the stable and postexacerbation patient groups pre-PR CAT score (<italic>P</italic> = .05) was observed. There was no significant difference in post-PR CAT scores or change in CAT scores between the stable and postexacerbation groups. There was a significant difference in pre- and post-PR walking test results between the groups. The improvement in the Endurance Shuttle Walking Test (ESWT) in the stable group was greater (<italic>P</italic> < .05).</p> </sec> <sec> <title>CONCLUSIONS:</title> <p>Postexacerbation PR patients had a worse CAT score prior to PR when compared with a stable PR population, but both groups made improvements in CAT following completion of PR.</p> </sec> </abstract>
