Abstract [en]

Background: Long-term oxygen therapy (LTOT) improves the survival time in chronic obstructivepulmonary disease (COPD) complicated by severe hypoxemia. Despite warnings about potentialdangers, a considerable number of patients continue to smoke whilst on LTOT. The incidence ofburn injuries related to LTOT is not known. The aim of this study was to estimate the rate of burninjury that required contact with health care during LTOT.Methods: a prospective, population-based, consecutive cohort study of people starting LTOT fromany cause between 1 January 1992 and 31 December 2009 in the Swedish national Register ofRespiratory Failure (Swedevox).Results: Between 1992 and 2009, 12,497 patients (53% women) started LTOT and were includedin the study. The mean (SD) age was 72 ± 9 years. The main reasons for starting LTOT were COPD(75%) and pulmonary fibrosis (15%). Only 269 (2%) were active smokers at starting LTOT. Themedian follow-up time to event was 1.5 (P25 to P75, 0.55 to 3.1) years. In total, 17 patients had adiagnosed burn injury during LTOT in 27890 person-years of follow-up. The rate of burn injuryduring LTOT was 61(95% CI, 36-98) per 100.000 person-years. Of the 17 burn injuries, five wereinhalation injuries and 12 skin injuries (3 third degree burns and one second degree; six (50%) werefacial burns). Two deaths were related to burn injury during LTOT. There was no significantdifference in the rate of burn injury between ever-smokers and never-smokers neither between menand women.Conclusion: the rate of burn injuries in patients with LTOT seems to be low in Sweden. This couldbe attributable to Swedish strict requirements on smoking cessation before LTOT initiation
