Time trends in pulmonary embolism mortality in France, 2000-2010

Abstract

BackgroundPulmonary Embolism (PE) is a potentially fatal complication of venous thrombosis. Recent and comprehensive estimates of PE incidence and mortality are scarce. Moreover, while contemporary mortality trends of PE would enable the evaluation of prevention and quality of care, such data are lacking. The aim of this study was to provide nationwide estimations of PE mortality and time trends in France between 2000 and 2010. MethodsMortality data were obtained from the French Epidemiology Center on medical causes of death. Mortality rates were calculated with PE as an underlying or one of multiple causes of death. The annual percentage changes were assessed using a Poisson regression model. Age-standardized PE mortality rates were also assessed. ResultsIn 2010, the overall age-adjusted PE mortality rate was 21.0 per 100000. This rate was 30% higher in men than in women and decreased by 3% per year between 2000 and 2010. Over this period, PE mortality declined in men and women over 55years but only slightly decreased in patients younger than 55. Cancer, obesity, osteopathies and complications of surgery were often coded as the underlying causes of death when PE was an associated cause of death recorded on certificate. DiscussionThis study is the first to provide a contemporary and exhaustive nationwide estimation of PE mortality and time trends in France. The observed decrease in PE mortality between 2000 and 2010 is encouraging, but further efforts in prevention are needed to ensure that this reduction is widespread in all age groups.
