> 15,000 will fall each year, >6000 twice or more Most will not call for help >70/week will attend A&E or the MIU A similar number will call the ambulance service 350 hip fractures/year ~1000 other fragility fractures Average PCT & council costs on falls are £50m per annum Ageing demography means this will increase 50% by 2020 For a typical 300K PCT :
