The numbers of frail older persons using emergency departments are already considerable and will continue to increase over time. There are a number of issues related to the assessment and care of older patients that are significantly different to other patient groups. The traditional emergency department (ED) model focusing on rapid triage, treatment and throughput does not meet the needs of many older patients, who have complex presentations, and require comprehensive assessment and referral. In response to this, there are already a number of appropriate and innovative approaches to the care of the older patient demonstrated in the literature. Nurses have a crucial role in contributing to these approaches and in raising the profile of quality care of the older person. Some specific areas that ED nurses can focus on include a more comprehensive approach to assessment and discharge planning, improved communication with the patient and their personal carers, attention to basic nursing care, and making the physical environment safer and less stressful for the older patient. While developing collaborations with their aged care nursing colleagues is important, emergency nurses need to view care of the older person as a central part of their own core business.
