Background

Labeled vulva, showing external and internal views.
Pelvic anatomy including organs of the female reproductive system.
  • Male victim in 10% of cases
  • Toluidine blue: detects vulvar tears
  • Wood's lamp: detects semen stains

Risks

  • Pregnancy
    • Without contraception 1-5%
    • If mid-cycle (days 14-16) risk is higher
  • STD (5-10%)
  • HIV
    • Theoretically higher risk of transmission in sexual assault than consensual due to physiological factors
    • Consensual receptive vaginal intercourse 0.1-0.2%
    • Consensual receptive anal intercourse 0.5-3%

Clinical Features

  • History of sexual exposure without consent
  • May or may not have symptoms/signs of injury

Differential Diagnosis

Genitourinary Trauma

Psychosocial and Related

Evaluation

General

  • Check for life threats, emergent medical needs, and injuries first
  • If patient consents to forensic exam after medical evaluation
    • Ask patient not to change, shower, eat, drink, or wash hands
    • Do not give wet wipe and ask patient not to wipe when giving urine sample. Collect dirty catch urine
    • Defer GU examination if patient consents to SANE (sexual assault nurse examiner) exam

Labs

  • Pregnancy test
  • Rapid HIV
  • Hepatitis panel
    • Hepatitis B surface antigen
    • Hepatitis C viral load
  • RPR
  • Urine GC/chlamydia, if not collected by SANE
  • If considering HIV PEP, need baseline labs
    • CBC
    • Chemistry
    • LFTs

Management

Empiric Antibiotics for STDs[1]

HIV nonoccupational exposure algorithm
  • Ceftriaxone 500mg IM in a single dose (1000mg if weight >= 150 kg) AND
  • Doxycycline 100mg orally twice a day for 1 week AND
    • For pregnant patients, Azithromycin 1g orally in a single dose instead of doxycycline AND
  • Metronidazole 500 mg PO BID for 1 week AND
  • HIV post-exposure prophylaxis
    • Post-exposure prophylaxis (PEP) recommended as soon as possible if <= 72 hours since exposure AND
      • Assailant HIV positive
      • Assailant HIV status unknown, but patient's mucous membranes or non-intact skin exposed to blood, semen, vaginal secretions, or bloody body fluids

Pediatric Antibiotics for STDs

  • If patient is pre-pubertal, only treat with antibiotics if they test positive rather than empirically.
  • Pubertal patients should be given empiric antibiotics.
  • For patients who weigh > 45 kg, same as adult medications above
  • For patients who weigh <= 45 kg
    • Gonorrhea: Ceftriaxone 50 mg/kg IM (maximum dose 250 mg) in a single dose
    • Chlamydia: Doxycycline 2.2 mg/kg (maximum dose 100 mg) orally twice a day for 1 week
      • Doxycycline may be used in age < 8 for treatment durations <= 21 days[2][3]
      • If patient is pregnant or liquid doxycycline is not available for patients who cannot swallow pills, can give Azithromycin 60 mg/kg (maximum dose 1000 mg) orally in a single dose
    • Trichomonas: Metronidazole 15 mg/kg (maximum dose 670 mg or 2000 mg/day) orally three times a day for 1 week

Vaccines[4]

  • Tetanus vaccine
  • Hepatitis B post-exposure prophylaxis
    • Even if patient is vaccinated, give HBV vaccine booster shot, preferably within 24 hours of exposure
  • HPV vaccine for female patients age 9-26 and male patients 9-21 if patient has not already completed series of 3 vaccines


Remember to attend to patient's emotional needs as well, consider social work consult and/or offering support resources such as [Rape, Abuse & Incest National Network] 800-656-HOPE

Disposition

  • Typically outpatient
