  11. Management
    1. Emergency department empiric treatment
      1. Initiating empiric treatment for suspected STD prior to results (often delayed days) is appropriate
      2. Despite risk of overtreatment, treat for suspected Chlamydia and Gonorrhea (prevents spread, complications)
        1. Gonorrhea management
          1. Ceftriaxone 500 mg IM/IV for 1 dose (1 gram IM/IV if weight > 150 kg, dose increased in 2020) OR
          2. Gentamicin 240 mg IM and Azithromycin 2 g orally for one dose OR
          3. Cefixime 800 mg orally once is an alternative but NOT recommended due to Antibiotic Resistance
        2. Chlamydia management if not excluded (not indicated for Gonorrhea treatment without Chlamydia as of 2020)
          1. Doxycycline 100 mg twice daily for 7 days (preferred as of 2020) OR
          2. Azithromycin 1 g orally for 1 dose

      3. Avoid sexual contact until antibiotic course is completed
    2. Rescreening
      1. Routinely Rescreen positive STD cases in 3 months to identify new STD infections
      2. Rescreen pregnant women in 4 weeks after completing treatment, and again in 3 months, and in third trimester
      3. Only other indicated early rescrening at 7 to 14 days (screening for cure) is for pharyngeal Gonorrhea
      4. Peterman (2006) Ann Intern Med 145:654-72 [PubMed]
    3. Clinic Visits
      1. Symptomatic patients should have in-person clinical examinations
      2. Consider Telemedicine for Sexually Transmitted Infection screening in asymptomatic patients
        1. At-home Chlamydia trachomatis and NeisseriaGonorrhea tests are available (not FDA approved)
        2. Medical provider or nurse instructed sample self-collection can be instructed on Telemedicine
        3. At home Test Sensitivity may be lower, but allows for screening more patients with fewer barriers

  12. Management: Expedited Partner Treatment
    1. Empiric STI treatment for an asymptomatic sexual partner of a patient being seen for STI
      1. Patient positive for Chlamydia or Gonorrhea in last 60 days (or last sexual partner if >60 days)
      2. Symptomatic sexual partners should be medically evaluated
    2. Precaution: Legality of Expedited Partner Treatment varies by State in the United States
      1. http://www.cdc.gov/std/ept/legal/
      2. As of 2022, permitted in 46 states
    3. Patients may anonymously notify their partner
      1. https://tellyourpartner.org/
    4. Ideally sexual partners are seen for their own medical evaluations
      1. However, delaying their treatment until evaluation risks re-exposing treated patients
    5. CDC asks physicians to consider treating sexual partners of STD patients without a visit
      1. Employ in cases where sexual partner is unlikely to present for medical care
      2. Prescription for sexual partner's STD treatment is given to the patient being treated
      3. Some states may allow prescription labeled for "EPT" or "partner"
      4. Do not double up on prescription quantity for one patient (write 2 separate prescriptions)
    6. Example protocol for partner (prescriptions given to patient to bring to partner)
      1. Provider should ask about partner's medication allergies, other medications and pregnancy
      2. Written instructions should be given to the patient to convey to their sexual partner
      3. Patient and their partner should abstain from sex until both have completed antibiotic course
    7. Regimen
      1. Cefixime 800 mg (if partner will be seen, Ceftriaxone 500 mg IM/IV is preferred) AND
      2. Azithromycin 1 gram orally (or preferred option is Doxycycline 100 mg twice daily for 7 days)

Sexually Transmitted Diseases (C0036916)

Definition (MEDLINEPLUS)

Sexually transmitted diseases (STDs) are infections that you can get from having sex with someone who has the infection. The causes of STDs are bacteria, parasites and viruses. There are more than 20 types of STDs, including

Most STDs affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an STD, it can cause serious health problems for the baby.

If you have an STD caused by bacteria or parasites, your health care provider can treat it with antibiotics or other medicines. If you have an STD caused by a virus, there is no cure. Sometimes medicines can keep the disease under control. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading STDs.
