title: Risk factors for mortality after surgery of osteoporotic hip fracture in patients over 65 years of age.
abstract: OBJECTIVE
  To evaluate, from a clinical perspective, and with easily identifiable variables, those factors that influence the survival of patients admitted to a care unit designed for the comprehensive treatment of patients with hip fracture after being surgically treated.
  
  
  METHODS
  A prospective study was conducted on a cohort of patients (n=202) aged 65 years or older with a low impact hip fracture, who were surgically intervened in a tertiary hospital. An analysis was performed to determine mortality at 90 days, and at one and 2years after surgery using demographic, clinical, analytical, and functional variables.
  
  
  RESULTS
  The independent risk factors of mortality in the 3periods analysed were age (P=.047, P=.016, and P=.000 at 90 days, 1, and 2 years, respectively) and a low Barthel index (P=.014, P=.005, and P=.004 to 90 days, 1, and 2 years, respectively). Male sex (P=.004) and a high risk for anaesthesia (P=.011) were only independent risk factors of mortality at 2years after surgery.
  
  
  CONCLUSIONS
  Age and dependency were the major determining factors of mortality at 30 days, 1, and 2 years after surgery for hip fracture. Both are easily measurable to identify patients susceptible to poor outcomes, and could benefit from a more thorough care plan.
