Life Expectancy of Older People Living in Aged Care Facilities after a Hip Fracture
Abstract Little is known about life expectancy in nursing home residents with hip fracture. We assessed life expectancy of 240 residents of residential aged care facilities who were aged more than 70 years old and experienced recent hip fracture treated with surgery. 149 deaths occurred over a mean follow-up of 1.2 years. Being female (coefficient (β) = 0.86, 95% confidence interval (CI): 0.39, 1.34; p = 0.0004) was associated with longer life expectancy. Increased age was associated with shorter life expectancy (β=-0.06, 95% CI: -0.10 to -0.02, p = 0.0043). Relative to severe cognitive impairment, normal or mild-cognitive impairment (β = 1.18, 95% CI: 0.05 to 2.31, p = 0.0414) and moderate cognitive impairment (β = 0.56, 95% CI: 0.07 to 1.04, p = 0.0237) were associated with longer life expectancy. Mortality rate within three months after hip fracture was 118 cases per 100 person-years while the mortality rate for the whole study period was 51.3 deaths per 100 person-years. For females with hip fracture, life expectancy was 8.2 years at 70 years of age; 4.8 years at 80 years of age; and 2.8 years at 90 years of age. For males with hip fracture, life expectancy was 3.8 years, 2.2 years and 1.3 years at 70, 80 and 90 years of age, respectively.
