Falls by older people constitute approximately 5 percent of all emergency responses. Up to 25 percent of older people are not transported to hospital following paramedic attendance. Ambulance dispatch response to older adults is most common on Fridays, and least common on Sundays. Within the Australian population there is no difference in seasonal attendance in this cohort. While the pattern of ambulance use have been studied extensively, the associated costs which are influenced by a variety of factors are still being explored. This program of research aims to better understand what is driving costs within the ambulance service, explore pathways to optimise resource use and evaluate models of care to streamline health care provided to older adults.
