Objective:
The study aimed to describe the main characteristics of people treated with long-term oxygen therapy (LTOT) and the trends between 2006 and 2011 for prevalence and incidence.
Methods:
Data were provided from a sample comprising 1/97 of the permanent beneficiaries of the French health insurance. The sample contains anonymous socio-demographic characteristics and data on health care reimbursements. The analyses were carried out among adults aged 20 years and above who had received benefits on account of LTOT.
Results:
In 2011, 2.6% of adults were treated with LTOT, corresponding to around 135,000 people. The crude incidence rate was 0.9‰. The prescription of LTOT included LTOT alone (70%), LTOT associated with assisted ventilation (23%) and LTOT associated with continuous positive airway pressure (7%). About 45% of the patients were supported financially in the long-term illness program of the French Social Security because of severe chronic respiratory failure. Between 2006 and 2011, the age-adjusted prevalence rates increased by 2.9% per year in men and by 6.7% per year in women. The age-adjusted incidence rates remained stable in men (+1.6% per year, P=0.45) but increased in women (+4.7% per year, P=0.04). The median survival was 27 months.
Conclusion:
This analysis of the data demonstrates an increasing burden associated with LTOT in France from 2006 to 2011.
