Over 60% of falls experienced by older people result from multiple aetiological factors. Preventing falls in individual patients requires the identification and treatment of these interacting factors. Multifactorial interventions have been successful in some, but not all, fall prevention trials. Preventing falls in populations requires selection of the population most likely to benefit, and selection of the particular interventions shown to have been effective in this group. The implementation of preventive measures has been low despite strong evidence that fall and fractures can be reduced. Misconceptions about the potential for prevention in old age, the time to effect improvement, resource issues and the nature of the interventions contribute to the low uptake. An improved system of delivery of proven preventive measures is needed.
