OBJECTIVE
To estimate the proportion of visits to United States emergency departments (EDs) receiving a diagnosis of elder abuse using two nationally representative datasets.
DESIGN
Retrospective cross-sectional analysis.
SETTING
U.S. ED visits recorded in either the 2012 Nationwide Emergency Department Sample (NEDS), or the 2011 National Hospital Ambulatory Medical Care Survey (NHAMCS).
PARTICIPANTS
All ED visits by patients aged 60 years and older.
MEASUREMENTS
The primary outcome was elder abuse as defined by ICD-9-CM diagnosis codes. The proportion of visits with elder abuse was estimated using survey weights. Odds ratios (OR) were calculated to identify patient demographics and common ED diagnoses associated with elder abuse.
RESULTS
In 2012, NEDS contained 6,723,667 ED visits by older adults, representing an estimated 29,056,673 ED visits. Elder abuse was diagnosed in an estimated 3,846 visits, corresponding to a weighted diagnosis period prevalence of elder abuse in U.S. EDs of 0.013% (95% Confidence Interval (CI) 0.012– 0.015%). Neglect and physical abuse were the most common types diagnosed, accounting for 32.9% and 32.2% of cases, respectively. Multivariable analysis showed increased weighted odds of elder abuse diagnosis in females (OR 1.95, 95% CI 1.68–2.26), and patients with contusion (OR 2.91, 95% CI 2.36–3.57), urinary tract infection (OR 2.21, 95% CI 1.84–2.65), or septicemia (OR 1.92, 95% CI 1.44–2.55). In the 2011 NHAMCS dataset, zero cases of elder abuse were recorded among the 5,965 older adult ED visits.
CONCLUSION
Among US ED visits by older adults, the proportion of visits receiving a diagnosis of elder abuse is at least two orders of magnitude lower than the estimated prevalence in the population. Efforts to improve the identification of elder abuse in EDs may be warranted.
