About this study

Official title: Randomized Controlled Trial for a Sleep Study and Targeted CPAP Therapy for Obstructive Sleep Apnea to Reduce the Incidence Adverse Pregnancy Related Outcomes

Prospective, randomized controlled trial. Pregnant women in early pregnancy will be randomized to either the Sleep Study + CPAP (Continuous Positive Airway Pressure Therapy) group or to a Standard Prenatal Care group. Subjects in the Sleep Study + CPAP group will complete a sleep study (WatchPAT-200, Itamar Medical, Inc.) and have CPAP initiated if the Apnea Hypopnea Index (AHI) ≥5 as indicated, in early and late pregnancy, whereas the other group will receive standard prenatal care. All subjects will complete a sleep study again between 8 to 12 weeks postpartum.

Read the detailed description

Objective/Hypothesis: The purpose of this study is to determine if parturients identified as high risk for obstructive sleep apnea (OSA; defined as an apnea hypopnea index [AHI] ≥5 events/hour) who are randomized to receive an unattended sleep study during early and late pregnancy (early = between 6 and 16 weeks; late = between 27 and 33 weeks) plus initiation of CPAP therapy if the AHI ≥5 events/hour and standard prenatal care have a decreased incidence of adverse pregnancy outcomes (defined as a composite variable which includes gestational hypertension, preeclampsia, eclampsia, gestational diabetes, preterm birth, low birth weight, or stillbirth) at the time of delivery when compared to a group who receives standard prenatal care only (no sleep study and CPAP initiation). At 8 to 12 months postpartum subjects in both groups will complete a sleep study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Adverse Pregnancy Outcomes

    Number of participants with adverse pregnancy outcomes (composite outcome includes: gestational hypertension, preeclampsia, eclampsia, gestational diabetes, preterm delivery, low birth weight, or stillbirth)

    Measured: time of delivery

Secondary outcomes (4)
  1. Incidence of Obstructive Sleep Apnea (OSA) in Early Pregnancy - Treatment Group Only (6-16 Weeks)

    Measured: early pregnancy (6-16 weeks)

  2. Incidence of OSA in Late Pregnancy- Treatment Group Only (27-33 Weeks)

    Incidence and severity of OSA in late pregnancy- treatment group only (27-33 weeks). Data were not collected for Control group at this time point

    Measured: 27-33 weeks

  3. Incidence of OSA at 8 to 12 Weeks Postpartum in Treatment and Control Group

    Incidence and severity of OSA at 8 to 12 weeks postpartum in treatment and control group.

    Measured: 8-12 weeks postpartum

  4. Hospital Costs at Time of Delivery

    Hospital costs at time of delivery in treatment and control group.

    Measured: Hospital costs at time of delivery
