BODE index and quality of life in advanced chronic obstructive pulmonary disease before and after lung transplantation

Background The BODE index ( B ody mass index, O bstruction, D yspnea, E xercise), predicts the risk of death in patients with chronic obstructive pulmonary disease (COPD), and is used to identify candidates for lung transplantation. We hypothesized that a higher BODE index would be associated with worse health-related quality of life (HRQL) in advanced COPD, and with larger improvements in HRQL after transplantation. Methods In this cohort study ( n = 112), we administered the St. George's Respiratory Questionnaire (SGRQ), 36-Item Short Form (SF-36), Visual Analog Scale, Standard Gamble and EuroQol Group 5-Dimension (EQ-5D) index to otherwise healthy COPD patients with a FEV1
