Elder abuse and neglect: definitions, epidemiology, and approaches to emergency department screening.

Elder abuse and neglect is estimated to affect approximately 700,000 to 1.2 million elderly people a year with an estimated annual cost of tens of billions of dollars. Despite the large population at risk, its significant morbidity and mortality, and substantial cost to society, elder abuse continues to be underrecognized and underreported. This article aims to increase the awareness of elder abuse by reviewing the demographics, epidemiology, and risk factors of elder abuse, followed by a discussion of screening tools and ways to increase awareness and reporting.
