The estimated societal economic impact of Preterm Birth is at least $26.2 billion annually.

Lessons Learned: Unsuccessful Interventions
• Grand rounds/Resident lectures• Jodi sings a preterm labor song• Processes excluding patients• Failing to prioritize preterm birth
as an obstetric RISK event• Trying to communicate priorities
without data
Lessons Learned: Successful Interventions • Counseling at delivery of index pregnancy• Experiential counseling of patients by
residents• Focused identification of patients• Streamlined processes• Assigning 17OHp Resource RN • EMPOWERED Patients are ready for 17Ohp• Audit and feedback of providers• Partnership with local DPH & CHC’s

ZIKA
Zika Virus• Flavivirus transmitted by an infected Aedes mosquito. • Clinical manifestations: low-grade fever with
maculopapular rash, arthralgia, non-purulent conjunctivitis.
• Incubation: between 2-14 days, illness is usually mild.• Associated with Guillain-Barré syndrome, fetal loss, and
congenital microcephaly.

Diagnosis of Zika Virus infection
• Maternal: – Serum reverse-transcription polymerase chain reaction
(RT-PCR) testing or antibody (IgM, IgG) serology 7 days after symptom onset.
• Intrauterine infection (positive or inconclusive Zika laboratory test results) – diagnostic amniocentesis– serial ultrasonography
• Newborn – Cord Blood Serum screening/Placental pathology
ACOG. (2016). Practice Advisory: Updated Interim Guidance for Care of Obstetric Patients And Women Of Reproductive Age During a Zika Virus Outbreak.
Association Between Zika Virus Infection and Microcephaly: The Data
Schuler-Faccini L, R. E., Feitosa IM et al. (2016). Possible Association Between Zika Virus Infection and Microcephaly — Brazil, 2015. MMWR Morb Mortal Wkly Rep, 65, 59–62. doi: http://dx.doi.org/10.15585/mmwr.mm6503e2
• Retrospective review of 37 cases of confirmed congenital microcephaly after birth.
• Exposure to Zika virus: presence of maternal rash, residence in or travel during pregnancy to areas of Zika exposure
• All were negative for syphilis, toxoplasmosis, rubella, cytomegalovirus, and herpes simplex virus infections.
• Weaknesses: – Media coverage lead to increased
surveillance and measurement of HC, thus increased number of cases reported.
– Zika virus was not serologically confirmed on infants or mothers, and thus presence of a rash can lead to recall bias.
Current Recommendations for Zika virus evaluation in Pregnancy• SMFM:
– If fetal HC is >2 SD below the mean, careful intracranial US for anatomy.
– Diagnosis of microcephaly is > 3SD below mean– If the intracranial anatomy is normal, recommend follow
up ultrasound in 3-4 weeks• ACOG:
– Avoiding travel to areas of Zika exposure during pregnancy.– If travel cannot be avoided, use EPA-approved bug spray with
DEET, covering exposed skin, staying in air-conditioned or screened-in areas, and treating clothing with permethrin
– If partner has traveled to ZEA use condoms remainder pregnancySMFM. (2016). SMFM Statement: Ultrasound Screening for Fetal Microcephaly Following Zika Virus Exposure.

Prenatal Zika Screening at BMC: Protocol • Universal Screening:
– at Intake/F/up Ob visit – ATU Fetal survey
• Have you or your partner been outside the US during your pregnancy? • YES -ZIKA ENDEMIC AREA• Entered into EPIC: Potential Zika Exposure
• Did you have mosquito bites, illness with fever, or red eyes? – YES or returned W/IN 12 weeks
• Offer serum screening and recommend • Serial US for fetal growth
35
Prenatal Zika Screening at BMC: Current stats• 65 women screened positive since 2/7/16• 30 women accepted serum screening• 30 pending serum screens• 2 near term patients with fetal growth delay
without criteria for microcephaly• 1 delivery (last week) of IUGR baby to screen
positive Mother– False negative Head Circumference in utero– Postnatal diagnosis of Microcephaly
36
BMC Protocol:High Risk + Zika Screen Mothers• Any Mother positive blood test• Any Mother blood test without result and ANY
clinical finding• Any screen positive Mother with ultrasound
findings of: – IUGR– CNS structural abnormality– Microcephaly diagnosis
37
Ideal Workflow for High risk + Zika Screen: Per MFM Yarrington/Pedi ID Barnett team
• Spreadsheet of all screen high risk Mothers and EDD’s to Pedi ID team
• Mother/Baby identified at admission to L&D and Pedi team notified
• Cord blood collected/held and placenta sent to path
• Pedi team notified of High risk screen positive baby at nursery arrival
