Abstract
To the authors’ knowledge, no study has been conducted on life expectancy for aged care facility residents with hip fracture. We assessed life expectancy of 240 residents of aged care facilities in Australia who experienced recent hip fracture treated with surgery. 149 deaths occurred over a mean follow-up of 1.2 years. Being female and having better cognition were associated with longer life expectancy. Increased age was associated with shorter life expectancy. The cumulative mortality rate within three months after hip fracture was 25.0% while the cumulative mortality rate for the whole study period was 62.1%. Life expectancy was 8.2 years, 4.8 years and 2.8 years for 70, 80 and 90-years old female patients. Life expectancy was 3.8 years, 2.2 years and 1.3 years for 70, 80 and 90 years old male patients, respectively. In conclusion, age, gender and cognition level were associated with life expectancy of hip fracture patients living in aged care facilities and their life expectancy was much shorter than that of the general Australian population.
Highlights
Life expectancy is defined as the average number of years a group of people is expected to live at a certain age, comparing hip fracture patients’ life expectancy with that of the general population could show a straightforward impact of hip fracture on the population and the disease burden
The life expectancy of a 70 year old female hip fracture patient living in an aged care facility could be 11 (19.3–8.2 = 11.1) years shorter than that of the Australian general population, and it could be 13 years (16.9–3.8 = 13.1) shorter for a 70 year old man
Our data suggested that age, gender and cognition were associated with life expectancy of hip fracture patients
Summary
Study design and participants.We performed secondary analyses using the data from the SouthernAdelaide Co-ordinated Regional Hip and Debility Rehabilitation Programme to Improve Quality of Life trial (SACRED). The trial was conducted between June 2012 and December 2014; for mortality data, the last follow up was 18 December 2015. Participants unable to provide informed consent or obtain consent from a suitable proxy, had pathological and peri-prosthetic fractures, had a terminal illness and were receiving palliative care, had a hip fracture treated non-surgically or were unable to follow a one-step command due to cognitive impairment at recruitment were excluded from the s tudy[13]. The outcome variable was survival time after hip fracture, calculated as date of death (all cause) or date of last follow up minus date of hip fracture. For patients surviving past 18 December 2015, the censored follow up time was calculated as 18 December 2015 minus the date of hip fracture. For patients who were lost to follow up or withdrew, survival time was calculated as date of last contact minus date of hip fracture
