Multicenter Study Comparative StudyEnhanced persistence with tiotropium compared with other respiratory drugs in COPD.
Tiotropium is a once-daily inhaled anticholinergic maintenance treatment with demonstrated effectiveness in chronic obstructive pulmonary disease (COPD). ⋯ Persistence with tiotropium was higher compared to other inhaled respiratory drugs in COPD in clinical practice.

Multicenter StudySurvival and future need of long-term oxygen therapy for chronic obstructive pulmonary disease--gender differences.
We aimed to study trends in gender-related differences in incidence, and prevalence for long-term oxygen therapy due to chronic obstructive pulmonary disease. Another aim was to study survival after onset of oxygen therapy. Prospectively followed were 5689 Swedish patients, who were prescribed oxygen therapy because of chronic obstructive pulmonary disease from 1987 to 2000. ⋯ In conclusion, the incidence and prevalence for long-term oxygen therapy increases more rapidly among women than in men. This is probably due to the increased frequency of smoking in women compared with men and a higher susceptibility to develop severe hypoxaemia in women. The survival is better in women with long-term oxygen therapy than in men.
