Chronic obstructive pulmonary disease assessment test for the measurement of deterioration and recovery of health status of patients undergoing lung surgery.
Abstract
Patients with early lung cancer often undergo surgery. However, surgery usually results in a decline in health-related quality of life (HRQL). Several questionnaires have previously been used to assess HRQL but some are impractical for clinical use. The chronic obstructive pulmonary disease assessment test (CAT) is simple and has been widely used in respiratory diseases but not for lung cancer. We therefore conducted this study to clarify the role of the CAT in postoperative deterioration and recovery of HRQL.
