Assumptions

  • 33% of over 60yrs of age fall each year.
  • Falls reduced 40% by intervention (30-50% reduction reported in literature).
  • Assessments of falls are carried out routinely using standard TUG.
  • Cost per fall is average cost per fall for the organisation.
  • Figures for cost of falls and related injuries are those reported in the literature for the US.
  • Falls per patient per year is the average number of falls afflicting those patients who fall.
  • 20% of falls result in serious injury.
  • Cost of falls per organisation is calculated as number of falls multiplied by cost of falls.
  • Kinesis figures for QTUG and optimal TUG performance are based on statistically optimised models.
  • Literature figures for TUG performance: Thrane et al; Tromso study.


Lexicon

  • QTUG refers to Quantitative Timed Up and Go.
  • TUG refers to standard (stopwatch-timed) Timed Up and Go test.
