Traumatic Injuries Due to Interpersonal and Domestic Violence in the United States.

BACKGROUND

Domestic and intimate partner violence (DV) are under-reported causes of injury. We describe the health care utilization of DV patients, hypothesizing they are at increased risk of mortality.

METHODS

We queried the 2014 Nationwide Emergency Department Sample for adult patients (18 y and older) with a primary diagnosis of trauma. DV was abstracted using International Statistical Classification of Diseases, ninth Revision codes for partner or spouse intimate violence, abuse, or neglect. The primary outcome was mortality; secondary outcomes included admission rates and charges.

RESULTS

Among 14 million trauma patients, 654,356 (5.0%) had a diagnosis of DV. Compared with other trauma patients, DV patients were younger (34.6 versus 46.8 y, P < 0.001), more often male (69.5% versus 50.1%, P < 0.001), and more likely to be uninsured (31.5% versus 15.6%, P < 0.001). 9154 (1.4%) were injured because of intimate partner violence, of which 90.2% were female. Drug and alcohol abuse (22.2%), anxiety (1.8%), and depression (1.3%) were high among all DV trauma patients. DV emergency department charges were higher ($4462 versus $2,871, P < 0.001). In adjusted analyses, DV trauma patients had 2.1 higher odds of mortality (aOR: 2.31, P < 0.001). DV trauma patients were also associated with a $1516 increase in emergency department charges compared with non-DV trauma patients (95% CI: $1489-$1,542, P < 0.001).

CONCLUSIONS

Injuries related to all types of DV are emerging as a public health crisis among both genders. To mitigate under-reporting, it is important to identify at-risk patients and provide them with appropriate resources.
