Sexual history and physical examination
A complete sexual history and risk assessment should be performed at a complete initial or annual visit and as indicated. Routinely updating the sexual history and risk assessment is important to normalize these questions within the frame of the person’s overall health, and it may be valuable in reducing stigma. This routine approach may be important particularly for younger patients and others whose risk for STDs may change frequently and dramatically.
Creating a safe space that permits privacy and assurance of confidentiality may help build trust and set the stage for disclosure. The American College of Obstetricians and Gynecologists recommends that all young people have time alone without parents for confidential counseling and discussion.15 All states allow minors to consent for STD services themselves, although 11 states limit this to those beyond a certain age.16
The CDC recommends using the 5 P’s—partners, practices, protection, past history of STDs, and prevention of pregnancy—as a guide for discussion.14 ObGyns are more likely than other providers to perform this screening routinely. While a pelvic examination should be available for STD evaluation as needed, it is not required for routine screening.
Prevention
ObGyns should employ several recommendations for STD prevention. These include providing or referring patients for vaccination against hepatitis B and human papillomavirus and providing brief STD/HIV prevention counseling along with contraceptive counseling. ObGyns should be familiar with HIV pre-exposure prophylaxis (PrEP) and nonoccupational postexposure prophylaxis (nPEP) and provide risk assessment, education, and referral or link to HIV care. Providing these services would improve access to care and further remove barriers to care. ObGyns also could consider providing condoms in their offices.14
Screening
STD screening of women at risk is critical since more than 80% of infected women are asymptomatic.8 Because young people are disproportionately experiencing STDs, annual screening for chlamydia and gonorrhea is recommended for women younger than 25 years. For women older than 25, those at increased risk can be screened.
Risk factors for chlamydia infection include having new or multiple sex partners, sex partners with concurrent partners, or sex partners who have an STD. For gonorrhea, risk factors include living in a high-morbidity area, having a previous or coexisting STD, new or multiple sex partners, inconsistent condom use in people who are not in a mutually monogamous relationship, and exchanging sex for money or drugs. Screening for syphilis in nonpregnant women is recommended for those who have had any sexual activity with a person recently diagnosed with syphilis or those who personally display signs or symptoms of infection.17
STD screening is especially important for pregnant women, and treatment of infections may improve pregnancy outcomes. The CDC recommends screening at the first prenatal care visit for chlamydia and gonorrhea in pregnant women younger than 25 years of age and in older pregnant women at increased risk; women younger than 25 years or at continued high risk should be rescreened in their third trimester. The CDC recommends screening all women for syphilis at their first prenatal care visit and rescreening those at high risk in the third trimester and at delivery (TABLE).18
