Mean age at start on LTOT was 74.0 (SD: 9.4), and 60.1% were females. Most of the patients (85.3%) started LTOT in connection with discharge after hospitalisation for an exacerbation. During the study, this proportion of patients increased from 76.5% to 91.7%.The median survival was 1.5 years – better for females than males (1.69 versus 1.26 years; p<0.001) and better for patients who started LTOT from the outpatient clinic compared to patients who started LTOT after a hospitalisation (hazard ratio (95% CI): 0.85 (0.80-0.90). During the study period, the survival for all patients didn’t change (p=0.4), but the difference in survival between women and men increased significantly. The hazard ratios (95% CI) for men compared to women starting in 2001 was 1.16 (1.03-1.30) in 2001 versus 1.41 (1.22-1.63) in 2010; increasing 1.022 (1.007-1.037) per year, adjusted for start of LTOT after hospitalisation.Conclusions: The difference in survival between women and men increased significantly from 2001 to 2010.
