About this study

Official title: Community-based Fetal Ultrasound and Care Navigation: An Approach to Engaging Pregnant Women With Substance Use Disorder in Prenatal Care and Substance Use Treatment

This exploratory study brings together an interprofessional team, novel tools, and innovative, community-driven care delivery approaches to improve health equity among mother-infant dyads impacted by substance use disorder and high risk for poor health outcomes. This study will test a community-informed and community-based intervention using a fetal ultrasound protocol, motivational interviewing techniques, strength-based education, and healthcare coordination strategies to reduce health disparities faced by women and their children.

Read the detailed description

Engaging women earlier in pregnancy through innovative, yet sustainable methods, will improve consistency in prenatal care and substance use treatment which will translate into substantially improved maternal and infant outcomes. The overarching premise is that successful engagement of women in accessible care during pregnancy will lead to earlier and more sustained prenatal care and treatment and lower risk for poor outcomes. This study is a multi-pronged approach to offer: (1) community-informed and community-located protocols to engage individuals into prenatal care as early as possible; (2) a novel fetal ultrasound protocol to enhance maternal-fetal connection and stimulate motivation for self-management and prenatal care; and, (3) navigation and care coordination, to connect individuals to personalized services and treatment. The NEXUS intervention is based on the idea that visualizing the fetus and seeing behavioral patterns in-utero will increase a person's sense of attachment to the fetus and in turn increase motivation for self-care and avoidance of risky behaviors. The NEXUS protocol includes a standardized fetal neurobehavioral assessment, measures of fetal growth, and, importantly, a component of 'attachment promotion' as it is a natural extension to share with the pregnant person the behavioral and social strengths of their unborn child. As the woman observes the fetus on the monitor (a second external monitor is set up for easy viewing by the mother), she may also feel fetal movement simultaneously in the womb (after 23 weeks gestation), creating a visual and sensory link between the mother and fetus. A trained nurse or ultrasonographer shares observations of fetal behavior with the mother and others if present. The family is given pictures and videos of the infant to take home with them. The NEXUS protocol will be repeated approximately 4 weeks after the first session, with educational content focused on the development of the fetus, changes in physical function, behaviors, and growth.

This is a small community-based randomized control trial in which 60 pregnant women with substance use disorder (or treatment for substance use disorder) will be offered two prenatal study visits, between the 2nd and 3rd trimesters, with two follow-up visits in the first 4 months after infant delivery. Participants will be recruited from communities with high health disparities and randomly assigned to either: (1) the Comparator Group which receives a standard non-diagnostic ultrasound with minimal interaction and no accompanying education or, (2) NEXUS Intervention Group which receives the NEXUS fetal ultrasound protocol that includes motivational interviewing and content specific to emotional and cognitive connection with the fetus. The prenatal ultrasound visits and the follow-up visits will be offered within the community in which the participant lives. All participants will receive standardized education, care coordination, and weekly contact with care navigators.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NEXUS interventionBehavioural

    During the fetal ultrasound protocol, the NEXUS intervention is added for the component of 'attachment promotion' as it is a natural extension to share with the pregnant person the behavioral and social strengths of their unborn child. As the participant observes the fetus on the monitor (a second external monitor is set up for easy viewing by the mother), she may also feel fetal movement simultaneously in the womb (after 23 weeks gestation), creating a visual and sensory link between the mother and fetus. A trained nurse or ultrasonographer shares observations of fetal behavior with the mother and others if present. The nurse is also trained in motivational interviewing techniques to use the strengths of the mother and those attributed to her fetus to explore readiness to change and other motivational factors that may be barriers to health promotion.

  • Standardized Non-Medical fetal ultrasoundBehavioural

    A standardized protocol using non-diagnostic fetal ultrasound that includes basic maternal-fetal health assessment by a trained nurse, fetal neurobehavioral assessment, measures of fetal growth, and pictures \& videos given to parents.

What is being measured

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

  1. Study Retention

    Percentage of each group returning for a second study visit

    Measured: 10-26 weeks

  2. Parent Subjective Connection to Fetus/Infant

    Participants reported scores of maternal-fetal attachment at the Baseline visit and at last postpartum session; Maternal-fetal attachment scale; Parent-Infant Attachment Questionnaire at 12 weeks post-delivery; (0-5 score, higher is better)

    Measured: Baseline through 12 Weeks post-delivery

  3. Prenatal care utilization

    The number of prenatal care visits per week of gestation at delivery.

    Measured: Immediately following infant birth

  4. Substance use treatment utilization

    The number of substance use and mental health treatment visits per week of gestation at delivery.

    Measured: Immediately following infant birth

Secondary outcomes (4)
  1. Access to Care

    PRAMS access to care survey

    Measured: 26 weeks

  2. Perceived Stress

    Perceived Stress Scale

    Measured: 26 weeks

  3. Substance use in pregnancy

    Participants' reported substance use at weekly check-ins during and after pregnancy: total number of days using substances in pregnancy (tobacco, alcohol, illicit drugs, marijuana).

    Measured: Immediately following infant birth

  4. Obstetric complications

    The total number of Obstetrics Complications identified by participant reports and medical record occurring from pregnancy through 12 weeks postpartum.

    Measured: 12 weeks postpartum
