Self-Assessment - Composite Self Hip Fracture Risk Assessment

Background

  • The FRAX®1 tool has been developed by World Health Organization to evaluate fracture risk of patients. It is based on individual patient models that integrate the risks associated with clinical risk factors as well as bone mineral density (BMD) at the femoral neck.
  • SARC-F2 is a tool developed by Malmstrom TK and Morley JE, using simple questions to evaluate risk of sarcopenia.
  • Sarcopenia leads to limited mobility, consequently increasing the risk of fall and fracture, so there are close relationships between sarcopenia and fracture. According to the research from our centre, comparing solely using FRAX® to predict fracture, using SARC-F in addition to FRAX® to predict hip fracture can increase the prediction sensitivity (true positive), which in turn enhances the efficacy of strategy for fracture prevention in elderly.
