Local trends in emergency department attendances by older patients in an ageing national population

Nursing-led aged care services were set up at our Emergency Department (ED) in 2004-05 to assist in the appropriate discharge of older patients. This study examined local trends in ED attendances by older patients. A retrospective study was conducted at an inner-city adult ED in a region with a 2.2% annual growth rate. Patient demographics, Australasian Triage Scale (ATS) category and admission/discharge status were collected from January 2002 to December 2006. Total ED attendances increased 7.7% from 66687 in 2002 to 71801 in 2006. Older patients' attendances, however, decreased 3.1% from 12356 to 11971. This decrease in ED attendances by older patients was unexpected. This may represent local population trends and/or be related to ED services designed to manage older patients and nursing home residents in the community. The planning of health services for older people therefore needs to take into consideration the influences on local trends in changing population demographics
