Child Abuse in Emergency Medicine
- Author: Lawrence R Ricci, MD; Chief Editor: Richard G Bachur, MD more...
Background
The general principles of emergency medical intervention with the physically abused child can be viewed as a series of diagnostic and therapeutic steps. These include suspecting abuse, establishing the diagnosis, treating injuries, addressing safety issues, reporting to appropriate child protective agencies and law enforcement, documenting findings, and recommending follow-up treatment.
Other components of the medical provider's role include expert testimony, when required, and referral, when available, to a child abuse medical specialist for definitive medical forensic assessment.
In executing these tasks, the most important treatment priority is ensuring the health and safety of the child.
Pathophysiology
The 4 overlapping categories of child abuse are as follows: physical abuse, sexual abuse, psychological abuse, and neglect. Each has unique characteristics and requires individual approaches to diagnosis and management.
Physical abuse is characterized by physical injury (eg, bruises, fractures, tissue disruption) resulting from hitting, punching, beating, kicking, biting, burning, shaking, or otherwise harming a child. The injury may have resulted from physical punishment. The intent of the abuser (to inflict injury or not) is not relevant to the medical diagnosis. Physical abuse of a child can be viewed as a spectrum of inflicted injuries. At one end of the spectrum lie inflicted minor bruises and lacerations, at the other end are severe multisystem trauma and death.
Sexual abuse is described in Pediatrics, Child Sexual Abuse.
Epidemiology
Frequency
United States
More than 3 million reports are made to child protective authorities in the United States each year. Every year, nearly 1.4 million children (approximately 3% of the population < 18 y) are victimized in some manner. The rate of child maltreatment in the United States is 12.3 per 1000 children. One in 50 infants are victims of nonfatal child abuse or neglect yearly. Each year, 160,000 children experience serious or life-threatening injuries. Approximately 1500 children die each year from abusive injuries or neglect. Children aged 0-3 years are most likely to experience abuse; 79% of children killed are younger than 4. Many of these seriously injured and murdered children have presented to the ED for initial care.[1]
Mortality/Morbidity
- Apart from the obvious physical sequelae of abuse (eg, death, traumatic brain injury, disfigurement), long-term mental health consequences of physical abuse include violence, criminal behavior, substance abuse, self-injurious and suicidal behavior, depression, anxiety, and other mental health problems.
- A small but significant number of abused children, although by no means a majority, later abuse their own children.
Race
Physical child abuse affects children of all ethnic groups and socioeconomic status. However, anything that increases stress on a family such as poverty or unemployment increases the risk of abuse. At the same time, it is important for clinicians to not make the mistake so well documented in the literature of failing to suspect injuries in infants whose caretakers appear to have a higher socioeconomic status.
Sex
Although female victims are more commonly reported in instances of child sexual abuse, no gender preponderance exists in child physical abuse. However, several studies have demonstrated a statistically significant though small increase in frequency of abusive head injuries in male infants as opposed to female infants.
Age
Physical abuse can occur at any age.
- Infants are more vulnerable to fatal head trauma, whereas toddlers are more vulnerable to fatal abdominal trauma.
- The incidence of physical abuse generally decreases during early school years but then increases slightly during adolescent years.
