Summary

Targeted human immunodeficiency virus (HIV) screening in pregnant women missed over 40% of cases. Routine HIV testing for all expectant mothers significantly improves detection rates, enhancing maternal and infant health outcomes.

Area of Science:

  • Public Health
  • Infectious Diseases
  • Obstetrics and Gynecology

Background:

  • Current guidelines in developed nations advocate for human immunodeficiency virus (HIV) testing in pregnant women based on identified risk factors.
  • This risk-factor-based approach may not effectively capture the full scope of HIV seroprevalence within pregnant populations.

Purpose of the Study:

  • To evaluate the effectiveness of risk-factor-directed HIV screening versus universal screening in pregnant women.
  • To determine the impact of routine HIV testing on detection rates among expectant mothers in an inner-city setting.

Main Methods:

  • A prospective study was conducted involving 2724 pregnant women in Baltimore, USA.
  • The study compared the projected detection rate of HIV-seropositive women under risk-factor-based screening versus universal screening.

  • All participants were offered counseling and HIV testing.

    • Main Results:

    • Applying risk-factor-based screening guidelines would have identified only 57% of HIV-seropositive pregnant women.
    • Offering universal counseling and HIV testing increased the detection rate to 87%.
    • A significant proportion of HIV infections in pregnant women were missed by targeted screening methods.

    Conclusions:

    • Screening pregnant women for HIV based solely on admitted risk factors is insufficient for effective case detection.
    • Routine HIV screening for all pregnant women is recommended to improve identification of infected individuals.
    • Universal HIV testing in pregnancy is crucial for timely intervention and prevention of mother-to-child transmission.
