Fracture-related mortality in southern Sweden: A multiple cause of death analysis, 1998-2014.

PURPOSE: To assess fracture-related mortality among adults (aged ≥20years) in southern Sweden using multiple causes of death approach. METHODS: All death certificates (n=201 488) in adults recorded in the region of Skåne from 1998 to 2014 were examined. We identified fracture-related deaths and computed mortality rates by sex, age group, and fracture site. Temporal trends were evaluated using joinpoint regression and associated causes were identified by age- and sex-adjusted observed/expected ratios. RESULTS: Fractures were mentioned on 6 226 (3.1%) death certificates, with majority of these occurred among women (60%) and those aged≥80years (77%). While hip was the most common site overall (61% of all fracture-related deaths), skull was the most common site in people <60years (60% of all fracture-related deaths). Proportion of death certificates mentioning fracture was stable in women but increased by 0.4% (95% CI: 0.1 to 0.6) in men between 1998-2002 and 2010-2014. The mean age at death was higher in death certificates mentioning fracture than those without and this gap widened over time. The mean age-standardized fracture-related mortality rate was 18.8 (14.0) per 100 000 person-year in men (women) and declined by 1.5% (1.3%) per year during 1998-2014. Injuries (84.6%) and cardiovascular disorders (64.6%) were the most common comorbidities on death certificates mentioning fracture. CONCLUSIONS: Fracture is a contributing cause of death in more than 3% of all deaths in southern Sweden with hip in lead among older and skull fracture among younger people. There was a slight increase in proportion of deaths associated with fracture in men but not women during the study period.
