Demand for Emergency Service Trends IN Years 2010-14 (DESTINY10.14): A population based study of Emergency Department utilisation and length of stay in New South Wales

Synopsis

Managing access and demand remains one of the fundamental challenges of modern emergency medicine (1). Understanding it at a population level allows better choices in the allocation of finite health resources, and provides a basis for which emergency department best practice models of care can be developed and improved across the state.

Previous studies have demonstrated an increased demand for emergency department care across Australia over the past decade (2). A major factor driving this trend is thought to be the ageing population across Australia (3). A preliminary study of data from 2001-2011 performed by the principal author, Michael Dinh using the Emergency Department Data Collection Registry (see below) showed not only an increase in overall ED presentation rates but a disproportionate increase in presentations for those aged 80 years and over. A similar study undertaken in metropolitan Melbourne from 1999-2009 showed age specific presentation rates highest in the elderly (4,5) However the type of presenting problem and re-presentation rates were not studied in that study.
The last in-depth analysis of ED demand in NSW was commissioned in 2006 and was a hypothesis driven analysis of supply and demand factors based on activity in 2004-06 (6). It concluded that the increase in demand seen in 2005-6 was multi-factorial with the main drivers being “primary care presentations” and an increase in chronic illness. Therefore there is a critical need further understand the drivers of ED demand at a population level.
