An update on pulmonary embolism-related mortality in Italy (2003-2015)

Abstract

Data regarding pulmonary embolism (PE)-related mortality in Italy are scarce. We assessed PE-related mortality and its time trend in Italy by using the World Health Organization (WHO) Mortality Database. The vital registration data of Italy from the WHO Mortality Database were analyzed for the period between 2003 and 2015, and compared with time trends in Southern Europe. Death was defined as PE-related when classified with specific codes for PE or limb vein thrombosis listed as the primary cause of death. This coding was based on the International Classification of Diseases, tenth revision. Overall, 28 647 PE-related deaths (10 178 men and 18 469 women) were recorded between 2003 and 2015. The observed age-standardized annual PE-related mortality rates were 2.5 per 100 000 men and 2.8 per 100 000 women. Moreover, PE-related mortality increased with age with a seemingly exponential distribution. Joinpoint regression analysis demonstrated a statistically significant linear decrease in age-standardized PE-related mortality of -0.21 (95% confidence interval -0.27; -0.15) and -0.22 (95% confidence interval -0.28; -0.16) deaths per 100 000 population for men and women, respectively. The Italian age-adjusted mortality rates appeared lower compared to overall Southern Europe, despite a similar decreasing trend over time.
