Chronic obstructive pulmonary disease in Brazil: mortality and hospitalization trends and rates, 1996–2008
OBJECTIVE: To evaluate the mortality and hospitalisation trends in Brazil caused by COPD during the period 1996–2008.
DESIGN: We used the health official statistics system to obtain data about mortality (1996–2008) and morbidity (1998–2008) due to COPD and all respiratory diseases (tuberculosis: codes A15–16; lung cancer: code C34, and all diseases coded from J40 to 47 in the 10th Revision of the International Classification of Diseases) as the underlying cause, in persons aged 45–74 years. We used the Joinpoint Regression Program log-linear model using Poisson regression that creates a Monte Carlo permutation test to identify points where trend lines change significantly in magnitude/direction to verify peaks and trends.
RESULTS: The annual per cent change in age-adjusted death rates due to COPD declined by 2.7% in men (95%CI −3.6 to −1.8) and −2.0% (95%CI −2.9 to −1.0) in women; and due to all respiratory causes it declined by −1.7% (95%CI 2.4 to −1.0) in men and −1.1% (95%CI −1.8 to −0.3) in women. Although hospitalisation rates for COPD are declining, the hospital admission fatality rate increased in both sexes.
CONCLUSION: COPD is still a leading cause of mortality in Brazil despite the observed decline in the mortality/hospitalisation rates for both sexes.
