Changes in fall-related mortality in older adults in Quebec, 1981-2009

Abstract

Introduction: Our purpose was to evaluate changes in fall-related mortality in adults aged 65 years and over in Quebec and to propose a case definition based on all the causes entered on Return of Death forms. Methods: The analysis covers deaths between 1981 and 2009 recorded in the Quebec vital statistics data. Results: While the number of fall-related deaths increased between 1981 and 2009, the adjusted falls-related mortality rate remained relatively stable. Since the early 2000s, this stability has masked opposing trends. The mortality rate associated with certified falls (W00-W19) has increased while the rate for presumed falls (exposure to an unspecified factor causing a fracture) has decreased. Conclusion: For fall surveillance, analyses using indicators from the vital statistics data should include both certified falls and presumed falls. In addition, a possible shift in the coding of fall-related deaths toward secondary causes should be taken into account.
