Excess mortality of 1year in elderly hip fracture patients compared with the general population in Beijing, China.

Abstract

This study aims to assess the incidence and excess mortality of hip fracture patients aged 60years or older from a municipal population database of Beijing. We retrieved the Beijing municipal health insurance database of 2013 to identify beneficiaries who were at least 60years older as total population of this age group and obtained the number of mortalities in a year. Among those people, subjects who have suffered hip fractures during the year were selected and a determination of the number of deaths in this period. Annual incidence of hip fracture, mortality, and excess mortalities was calculated and stratified by gender and age. During 2013, the annual incidence of elderly hip fracture in Beijing was 0.27% and 1-year mortality was 23.44%. Excess mortality odds ratios of males and females in three age groups were as follows: males, 2.23 (60-69years old, 95% CI, 1.43-3.49), 2.99 (70-79years old, 95% CI, 2.57-3.50), and 1.90 (≥80years old, 95% CI, 1.64-2.22 ) and females, 3.12 (60-69years old, 95% CI, 2.04-4.79), 1.93 (70-79years old, 95% CI, 1.64-2.27), and 1.36 (≥80years old, 95% CI, 1.21-1.55). Pulmonary complications were the leading cause of death, which accounts for 52.27% of all. Compared with the control population, hip fractures caused approximately twofold excess mortality rate during 1year 2014 for elderly citizens in Beijing. Future studies are needed to explore the actual mechanism to design the most effective strategies for optimizing recovery from hip fracture.
