Chapter 51 Sexual Assault
The U.S. Department of Justice defines rape as “[f]orced sexual intercourse including both psychological coercion as well as physical force. Forced sexual intercourse means penetration by the offender(s). This definition includes attempted rapes, male as well as female victims, and both heterosexual and homosexual rape. Attempted rape includes verbal threats of rape.”1 While each state has its own definition of rape, all states include in their definition the element of force and lack of consent. Although the terms “rape” and “sexual assault” are frequently used interchangeably, the Rape, Abuse, and Incest National Network (RAINN)2 refines this definition, classifying sexual assault as unwanted sexual contact that stops short of rape or attempted rape. Most state statutes currently define rape as “nonconsensual oral, anal, or vaginal penetration of the victim by body parts or objects using force, threats of bodily harm, or by taking advantage of a victim who is incapacitated or otherwise incapable of giving consent.”3
Although the total number of sexual assaults has dropped nearly 60% in the United States in the past decade2, the incidence is still staggering. It is estimated that one in six American women will have been the victim of an attempted or completed rape some time in her life and that someone is sexually assaulted in America every 2 minutes.2 In 2010, there were 188,380 incidents of rape or sexual assault.4 A 2006 study noted that 22% of women report having been forced to do “something sexual” in their lifetimes.5 According to the 2000 National Violence Against Women Survey,6 a very conservative estimate of the number of female rape victims treated by emergency department (ED) personnel in the 12 months preceding the survey was almost 129,000.
General Approach
Given these statistics, it is nearly inevitable that an emergency nurse will be responsible for the care of a sexual assault survivor at some time during his or her career. The emergency nurse is a key member of the treatment team and is instrumental in coordinating the multiple activities necessary to ensure that the simultaneous goals of compassionate emergency care and forensic evidence collection are met.7 The Emergency Nurses Association (ENA) advocates that these at-risk victims “receive appropriate and sensitive care that addresses their medical, emotional, and legal needs.”7 It is important to recognize that sexual assault is a crime of violence, not of sexual gratification8 and, as such, can cause concomitant physical injuries as well as long-lasting detrimental effects on the survivor’s psychological well-being and future interpersonal relationships. Because the ED is the first point of contact for many of these survivors, emergency nurses play a key role in their care, not only as that of health care provider but as that of evidence collector as well.9 As such, it is imperative that the emergency nurse approach the patient as well as the examination from an integrated, holistic psychological-social-legal perspective.
The Sexual Assault Nurse Examiner
Because of the intensely personal needs and legal implications inherent in the care of the sexual assault survivor, many EDs have adopted the Sexual Assault Nurse Examiner (SANE) model of care. SANE programs grew out of a need recognized by health professionals who care for sexual assault victims. These professionals recognized that the services provided in the ED to sexual assault victims were not at the same standard of care as for other populations of emergency department patients.10 The first SANE programs were established in Memphis, Tennessee, in 1976 and they have grown in number from 3 in the 1970s to more than 600 as of June 6, 2010.11 In addition, 17 schools offer forensic nurse degree programs at this time.
The benefit of SANE services was evidenced in a retrospective analysis of sexual assault victims presenting to a pediatric ED in a study by Bechtel, Ryan, and Gallagher.12 They found that patients whose care was directed by a SANE as compared to those whose care was not were more likely to have a full genitourinary examination documented. They were also more likely to have had appropriate testing for sexually transmitted infections, to have received pregnancy prophylaxis treatment, and to have been referred to a rape crisis center.12 Research has shown that additional benefits of a SANE program include the following:
• More victims make a police report and follow through with prosecution.
• Survivors experience a shortened treatment time in the ED.
• The emergency nurse and physician have more time to care for other patients.
• Survivors report that they feel a higher level of satisfaction and a decreased level of feeling victimized during the ED examination.
• A better chain of evidence is maintained and conviction rates are as good, if not better, than with non-SANE care.10
Triage
In addition to any physical pain from injuries incurred during the assault, patients presenting for treatment following sexual assault are in extreme emotional pain. Using a five-tier triage system that the ENA and American College of Emergency Physicians (ACEP) jointly recommend,13 these patients should be assigned a triage category of 2 on a scale of 1 to 5 (with 1 meaning resuscitation). These patients warrant a level 2 categorization because of the time-sensitive nature of their required treatment as well as the severity of their psychological pain.14 Following identification of the chief complaint, these patients should bypass the remainder of the triage process and be taken to a private treatment room if at all possible. This provides them with the maximum amount of privacy and assists in the preservation of forensic materials. In EDs with access to SANE services, the SANE should be notified at this time.
Primary Assessment
Aside from patients who present with obvious immediate threats to life, assessment should proceed in the usual manner, with an initial assessment of airway, breathing, and circulation. Sexual assault patients may sustain a wide array of physical injuries, dependent on the number of attackers, whether foreign objects were employed, and the overall violence of the incident. The Centers for Disease Control and Prevention (CDC)15 found that among sexual violence victims aged 18 years and older, 31.5% of women and 16.1% of men reported a physical injury as a result of a rape. While life-threatening injuries should be attended to immediately, care of other non–life-threatening injuries should wait until evidence collection has been completed, to maintain the integrity of any evidence collected.10
History
Following the initial assessment for life threats, a more detailed history and physical examination pertinent to the assault itself should take place. The history should include “an accurate and detailed description of the incident, which will guide forensic evidence collection.”16 In addition to a standard patient history, an obstetric and gynecologic (OB/GYN) history as well as additional elements specific to the assault should be attained. Elements to obtain are outlined next.8
Obstetric and Gynecologic History
Assault History
• Date, time, and place of the assault
• Events surrounding or leading up to the assault
• Description of the assailant and number of assailants
• Information regarding all acts perpetrated by the attacker
• Injuries associated with the assault
• Post-assault activities by victim (e.g., bathing, wound care, douching, eating, drinking, and clothing changes)
Physical Assessment
Basic Principles of Sexual Assault Evidence Collection
Because of the intensely personal and highly traumatic nature of sexual assault, many survivors delay seeking treatment. While patients may present at any time following an assault, in general a sexual assault evidence collection kit should be completed only when the attack has occurred within the previous 96 hours. If the assault took place more than 96 hours prior to the patient presenting for treatment, an evidence collection kit is generally not used, as the presence of any trace evidence is unlikely at that point. This time limit may change in the future, as it is dependent on the current sensitivity of forensic testing. Deoxyribonucleic acid (DNA) from suspects has been found in epithelial cells in the vaginal vault of patients for as long as 3 weeks post-assault and on the clothing for years.18
Some basic principles include the following:18
• Whenever possible, unbutton or unzip any clothing for removal.
• If the patient is able, have her or him undress while standing on a sheet so that trace evidence will fall on the sheet. The sheet is then preserved.
• If clothes must be cut, do not slice through stains, holes, tears, or buttonholes.
• Air-dry all physical evidence of the crime collected from the victim. Heat degrades biological samples. Fold clothing without shaking. Take care not to cross-contaminate the surfaces. Place individual items in paper collection containers that are sealed and labeled as described below.
• When moisture is needed to collect biological samples, slightly moisten (versus saturate) the tip of a cotton swab with sterile water. Moisture dilutes biological samples thereby reducing the chance of detecting scant amounts of DNA. Separate items as they are collected so that there is no transfer of trace evidence between objects. Dry the samples and place them in a separate, labeled envelope obtained from the sexual assault kit.
• For the vaginal examination, lubricate the speculum with tap water only, as other lubricants may affect test results and decrease sperm motility. A vaginal speculum is never used in prepubertal children without general anesthesia.
• Collect biological samples before any activity or procedure (catheter insertion, voiding, eating, smoking, drinking) that could result in the destruction of evidence. Dry the sample and place it in a separate, labeled envelope obtained from the evidence collection kit.
• Never place moist evidence in plastic or glass containers. Heat and moisture promote growth of mold and other organisms that destroy evidence. Collect and store specimens using paper or glass only, never plastic. Plastic does not breathe, and mold will grow.19
• After drying, place each cotton-tipped applicator (bulb end first) into a separate, labeled envelope obtained from the evidence collection kit. Ensure that all envelopes are sealed properly.19
• Properly seal all envelopes; do not lick or your DNA will be on the envelope.
• If the specimen was once living (e.g., blood or other body fluids), refrigerate it after collection.19
• Do not touch objects that may contain fingerprints (i.e., knife, gun, bullet, cartridge case). Package the evidence to preserve the prints.19
• Sterile collection is not essential but it is important to change gloves between sites to avoid cross-contamination.19
