- Abstract:
- This study aimed to estimate time-trends in the lifetime risk of hospitalisation with exacerbation of chronic obstructive pulmonary disease (COPD) in Denmark.During the period from 1994 to 2008 a register-based cohort study was conducted covering each subject in the entire population of Denmark (5.43 million in 2008).Based on previously validated diagnosis codes, all COPD hospitalisations were identified. Individual look-back periods of 8 years were used to determine first-time hospitalisations. From year 2002 to 2008 all first-time COPD hospitalised subjects aged 30 years and above were identified. The calculation of lifetime risk was based on age- and sex-specific first-time COPD hospitalisation rates and rates of COPD hospitalisation-free survival, assuming them to be calendar time stationary.The study included 23.9 million person-years of risk time and identified 48 959 first-time COPD hospitalisations. For 30-year-olds in Denmark, the lifetime risk of COPD hospitalisation was 12.0% (95% CI 11.9-12.2) for females and 10.9% (95% CI 10.8-11.1) for males. Trends were generally equal in both sexes. During the period from year 2002 to 2008, the rate of first-time COPD hospitalisations decreased, while the survival of never COPD hospitalised subjects increased. In consequence the lifetime risk of COPD hospitalisation remained constant.
