title: Raising the index of suspicion for elder abuse: cognitive impairment, falls, and injury patterns in the emergency department.
abstract: Cognitive impairment limits older adults' abilities to advocate for themselves, thus heightening their risk for abuse. Some older adults with cognitive impairments who seek emergency department (ED) services may present with injuries suspicious of abuse. A portion of these injuries may be erroneously attributed to accidents such as falls. A retrospective analysis of 2 years of ED data using International Classification of Diseases, Ninth Revision (ICD-9) codes was conducted focusing on characteristics of injuries sustained by persons with co-occurring cognitive impairment and fall status. Cognitive impairment was not significantly related to falls (P = .533). Findings suggest that persons with cognitive impairment have unique injury patterns based on fall status, which has implications for elder abuse screening. Injuries for persons with no fall history included injury to the upper limb (P = .004), contusions (P = .012), and open wounds (P = .000). An increased recognition of common injuries in older adults can aid in elder abuse assessment by providing a reference point for uncommon injuries.
