Introduction
Domestic violence (DV) is a public health issue which crosses families, communities, and populations.1–4 Some risk factors and social determinants of health that have an impact on the prevalence of violence are: hopelessness, unemployment (although it affects all social classes), access to firearms, lack of housing, lack of role models, mental illness, and substance abuse.1 2 DV includes violence against partners, children, parents, or the elderly, whereas intimate partner violence (IPV) involves violence that occurs in a close relationship and is not specific to only those associations with sexual intimacy. The Centers for Disease Control and Prevention (CDC) defines DV or IPV as ‘physical violence, sexual violence, stalking, or psychological harm by a current or former partner or spouse’.5 6 On average, 50 women in the USA are killed with a firearm by intimate partners each month. Abused women are five times more likely to be killed if the person abusing the woman owns a firearm.1 7 8 The American College of Obstetrics and Gynecologists issued a statement noting that women disproportionately experience IPV, and abusers with access to a firearm within those relationships are a key risk factor for intimate partner homicide.1 2 9
According to the CDC, one in four women and one in seven men in the USA have experienced violence (sexual, physical) and/or stalking from an intimate partner in their lifetime; and the risks to victims are potentially severe. CDC data link IPV with an increased risk of injury and death.1 7 10 11 Although both men and women are harmed by IPV, women more frequently experience severe consequences of IPV and suffer life-threatening injuries.12 13 The disproportionate impact of IPV on women is apparent in homicide data which demonstrate that 42% of female murder victims are killed by an intimate partner, as compared with 5% of men who sustain fatal injuries with an intimate partner as the perpetrator.12 14 15 Almost half of women murdered by an intimate partner have a documented emergency department (ED) visit within 2 years prior to their death.12 15 These patients often present with traumatic injuries, which provide surgeons, emergency physicians and nurses an opportunity to break the cycle of violence.12
In the USA, about 20 people per minute are physically abused by an intimate partner, which equates to 10 million people abused annually from intimate partners.16 17 Twenty-two percent of women and 14% of men are harmed by at least one act of severe physical violence by an intimate partner at some point in their lifetime. These data translate to an incidence of nearly 2.8 million women and more than 2.3 million men severely injured annually.1 7 17 This toll of abuse is significantly more common than other diseases, such as breast cancer and heart disease.18 Almost 23 million women and 1.7 million men have been the victim of completed or attempted rape at some point in their life.
There appear to be disparities regarding the impact of DV/IPV in certain ethnic populations, and among the lesbian, gay, bisexual, transgender, queer community.7 18 A recent survey indicates that higher rates for Native American women persist, but disproportionately high rates are now also observed in multiracial (56.6%) and non-Hispanic black (45.1%) women.7 19 Women with disabilities are more vulnerable to rape and sexual coercion, along with several forms of IPV.1 10
IPV is under-reported and often goes unrecognized by family members, friends, and healthcare providers. This may be due to a propensity of patients who experience IPV not to disclose the violence unless prompted by family, friends or healthcare professionals. Available data demonstrate that only about one in four women patients will offer spontaneous testimony of an IPV incident.12 20
No one is immune from IPV; not even surgeons or other physicians. Although the true prevalence of IPV among US surgeons is unknown, it is important to note that anyone can be a victim regardless of income, education, race, ethnicity, age, or professional role.16 Collectively, the authors of this article have eight physician colleagues who were killed by IPV.
Community violence exposure in the form of a child being subjected to either DV or IPV involving a parent deserves mention because it has direct bearing on the physical, mental, and emotional development of children. Increased stress levels among parents are often a significant predictor of physical abuse and neglect of children, in addition to neighborhood poverty.1 10 If the parent is unable to access professional support after DV or IPV, the exposed child will also not receive assistance or treatment. This may contribute to lifelong mental health and physical health problems for the child such as chronic disease, anxiety, substance abuse, depression and physical violence.1 19 21 The Family Justice Center (FJC) concept provides services to address root causes of these issues to mitigate preventable lasting effects.
Researchers estimate that upwards of 18.8 million children in the USA witness DV across their lifetime.22 23 Meta-analytic studies consistently find that children exposed to DV are at a higher risk for emotional, social, and behavioral difficulties both in the short term and long term.22 24–26 Moreover, children exposed to DV experience additional stresses associated with the trauma of repeated separations, child custody battles, and isolation from extended family supports. Children exposed to DV are also at a significantly higher risk for abuse and neglect.27 ,28 While the research on exposure to DV continues to emerge, existing evidence suggests these children are at risk for propensity to perpetuate the cycle of DV.27 29–31 The higher the exposure to childhood trauma, the higher the rates of impaired social, emotional and cognitive functions, health/behavioral risk factors, acute and chronic diseases, disability, early death and risk for intergenerational transmission of adverse childhood experiences.27 32 33 Given the prevalence of children exposed to DV in the USA and the negative consequences on their future, an effective system-level intervention is needed to provide children the opportunity to develop positive childhood events and positive coping mechanisms that allow for resiliency and ability to thrive in difficult environments.27
