Overview of perinatal HIV Perinatal Exposure-Any child born to an HIV
infected woman
Steps to prevention of perinatal HIV
• Infected-Any child born to an HIV infected woman and
Preventative factors determined to be HIV positive
• Uninfected Any child born to an HIV infected woman and
determined to be HIV negative
• Indeterminate- Any child born to an HIV infected woman
with insufficient test history to determine his/her HIV
status.

transmission from 2000 to 2008 Earlier encounters with HIV positive pregnant
Among HIV+ women delivering an infected infant: women decreases the likelihood of perinatally
• Hispanic and White women were disproportionately infected children
affected (2005-2008) • Early diagnosis of HIV
• Women predominantly received no prenatal care and • Ensure ARV therapy intake
received incomplete ARV therapy (2008) • Counseling on breastfeeding practices
Perinatally HIV infected and exposed children are
distributed throughout Texas (2005-2008)

Goal 1: Objective and Product Goal 2: Objectives
Goal 1: To improve access to necessary components Goal 2: Improve SOC through enhanced
for perinatal HIV prevention communication, knowledge, and cultural
• Objective: Identify labor and delivery hospitals with access competency among statewide stakeholders to
to ARV therapy for mother and child
• Rational:
prevent perinatal HIV transmission
– 11% of women received no ARV at L&D (2005-2007) • Objective 1: Developed guidelines for care
– 1% of infants received no ARV at birth (2005-2007)
• Objective 2: Develop prenatal HIV testing
• Product: Developed a survey instrument for pharmacy staff recommendations to harmonize with national
– 76 hospitals surveyed
testing guidelines
– 15-20% do not stock IV AZT or oral AZT

Timing of tests for pregnant women and infant specimen
• 1st test at first health care visit Test at labor and delivery if no documentation of test
• 2nd test at 32-36 weeks gestation in 3rd trimester
• At labor and delivery (if no documentation of 2nd test) • Make results available within 6 hours of collection
• Infant testing (if mother’s HIV status is unknown) Test infant if no documentation of maternal test in 3rd
Results available within 6 hours of collection trimester or not tested prior to delivery
• Test infant w/in 2 hours after birth and results made
available w/in 6 hours of collection
