Mortality and cause of death in hip fracture patients aged 65 or older: a population-based study.
Hip fracture is the most serious consequence of falling in older people with osteoporosis; 87% to 96% of hip fracture patients are 65 years of age or older. Hip fractures are associated with increased mortality rates; the magnitude of the increased mortality and the length of its duration, however, are unclear. One study stated that survival declines soon after hip fracture but thereafter parallels the expected survival of the general population. A recent systematic epidemiologic review however, showed that patients are at increased risk for premature death for many years after hip fracture.
Excess mortality after hip fracture may be linked to complications following the fracture, such as pulmonary embolism, infections, and heart failure. Factors associated with the risk of falling and sustaining osteoporotic fractures may also be responsible for the excess mortality. Excess mortality after fracture may be due to the individual characteristics of the person sustaining the hip fracture; e.g., low-bone density is associated with increased non-trauma mortality, even without fractures.
The purpose of the present study was to evaluate mortality and cause of death in patients after hip fracture surgery and to compare their mortality and cause of death to those in the general population.
The present study showed that during the follow-up up to 9 years, the age- and sex-standardized all-cause mortality of hip fracture patients was 3-fold higher than that of the general population. A similar trend was observed for each cause-of-death category > From Panula et al.; BMC Musculoskeletal Disorders (2011) 12:105. All rights resered to Biomed Central Ltd.
