Objective : To investigate the one-year mortality rate after osteoporotic hip fracture and to identify factors associated with
that mortality rate.
Material and Method: A retrospective review of 275 osteoporotic patients who sustained a low-trauma hip fracture and
were admitted in Chiang Mai University Hospital during January 1, 2006 to December 31, 2007 was accomplished. Eligibility
criteria were defined as age over 50 years, fracture caused by a simple fall and not a pathological fracture caused by cancer
or infection. Results of this one-year mortality rate study were compared to studies of hip fracture patient mortality in 1997
and the period 1998-2003.
Results : The average one-year mortality rate in 2006-2007 was 21.1%. Factors correlated with higher mortality were
non-operative treatment, delayed surgical treatment, and absence of medical treatment for osteoporosis. The 2006-2007
mortality rate was slightly higher than for the 1997 and 1998-2003 periods.
Conclusion : The one-year mortality rate after osteoporotic hip fracture of 21.1% was approximately 9.3 times the mortality
rate for the same age group in the general population, indicating that treatment of osteoporosis as a means of helping
prevent hip fracture is very important for the individual, the family, and society as a whole.
