Abstract
The present study was undertaken to assess the relationship between health-related quality of life (HRQOL) and bronchiolitis obliterans syndrome (BOS), as both represent important parameters of outcome after lung transplantation. HRQOL was measured both cross-sectionally and longitudinally by standardized patient self-administered questionnaires, including the Nottingham Health Profile, the State-trait Anxiety Inventory, the Zung Self-Rating Depression Scale, and the Index of Well-Being. Data were collected at 4 and 7 mo, and every 6 mo afterwards for as long as 49 mo post-transplantation. The number of patients who completed the questionnaires varied from 72 at 4 mo, to 27 at 49 mo after transplantation. Cross-sectionally, the patients with BOS reported persistently statistically significantly more restrictions on the dimensions energy and physical mobility of the Nottingham Health Profile compared with patients without BOS. Other domains, i.e., pain, sleep, social interaction, and emotional reactions, were not affected. Additionally, patients with BOS reported statistically significantly more depressive symptoms and anxiety 1 and 2 yr after transplantation. Results from the longitudinal analysis support these findings, although no change in depressive symptoms could be found after onset of BOS. This study suggests that all lung transplant recipients improve in HRQOL. The development of BOS, however, is associated with a significantly reduced HRQOL.
