Digitally Enhanced Peer Doula Model for Perinatal Patients With Substance Use Disorder (EMBRACE)
A Digitally Enhanced Model of Peer Doula Support for Substance Use Disorder and Peripartum Care
The goal of this pilot study is to learn if a digitally enhanced peer doula program for people with perinatal substance use disorders (PSUD) is feasible and acceptable to patients and staff at two clinics.
Participants will include staff members, such as healthcare providers, recovery support doulas, and administrators, who work at one of the two clinics. It will also include PSUD patients receiving care through the digitally enhanced peer doula program.
Participants will be asked to complete short surveys and take part in a one-time interview with research staff.
This study will also explore engagement in perinatal substance use disorder treatment and prenatal and postpartum visits.

Detaillierte Beschreibung
Over the past two decades, rates of substance use during pregnancy have increased fourfold. Overdose is a leading cause of mortality among patients with perinatal substance use disorders (PSUD). Interventions to address SUD during pregnancy and postpartum are critical to reduce mortality and the impact of SUD-related harms for parents and their infants.
Engagement in SUD and perinatal care can improve outcomes for PSUD and their infants, including reducing the risks of preterm delivery and low birthweight. Rates of adequate prenatal care receipt are low for PSUDs, with one recent study estimating that only an estimated 50% of PSUDs in the United States (US) receive adequate prenatal care. These healthcare disparities also extend to the postpartum period, where PSUDs have a 53% decrease in the odds of attending at least one postpartum obstetric visit, compared to patients without an SUD. PSUDs are also less likely to receive SUD treatment during the year postpartum due to lapses in health insurance. Stigma from health professionals and lack of trust in healthcare providers can prevent PSUD from seeking perinatal health services and SUD treatment. PSUD also report numerous barriers to effectively communicating with healthcare providers and want more evidence-based information about delivery, postpartum health, breastfeeding, and the impact of medication for opioid use disorder (MOUD) from their healthcare team. Lack of access to healthcare can have devastating consequences, including a return to substance use and increased risk of fatal overdose. Interventions improving engagement with prenatal and postpartum care and SUD treatment are urgently needed.
A growing body of research suggests that doula care may improve engagement in healthcare for patients with behavioral health conditions. A doula is a trained professional who provides comprehensive physical, emotional, and informational support to patients before, during, and/or after childbirth. Doula care has been widely studied, with reviews suggesting that doula support can decrease rates of preterm birth, Cesarean birth, and low birth weight babies.
Doula care promises to directly improve outcomes and care experiences for PSUD. A growing body of literature has studied how doula support may improve outcomes for patients with behavioral health conditions including postpartum depression and SUD. The Illinois Department of Health/Division of Substance Use Prevention and Recovery pilot specifically use peer doulas, who have dual certifications as certified peer support specialists and doulas. Peer doulas with experience in both SUD and perinatal care could be especially beneficial for PSUD and provide guidance in navigating both SUD and perinatal healthcare systems.
Only one known study has enrolled PSUD to examine their experiences with doula care during pregnancy and postpartum. Twenty-three patients with OUD who had engaged with the Philadelphia doula care model were enrolled in a mixed-methods study examining perceptions of engaging with a doula. Participants overwhelmingly reported positive experiences with the doula program, finding the program acceptable and helpful. They appreciated the ability to engage with the doulas through phone, text, video, or in-person in the community. Participants noted that the doulas helped manage their stress and anxiety, while providing critical assistance navigating the healthcare system. Importantly, participants and staff both agreed that doula involvement reduced perceptions of stigma from healthcare providers.

Patient Participants Cohort 1
Patient Participants who have not yet been exposed to the peer doula model of care or have been exposed for less than 30 days
|
In the digitally enhanced peer doula model of care, patients with perinatal substance use disorder are partnered with a recovery support peer doula who is able to provide synchronous or asynchronous support.
This support can include in-person and text-based and/or telehealth support, in addition to assistance scheduling and arranging transport to appointments for both SUD and peripartum care, and assisting with access to food, transportation and housing.
Additionally, these patients are offered a free smartphone and data plan for pregnancy and one-year postpartum.

Feasibility of Intervention Measure (FIM)
Zeitfenster: At enrollment
|
Site staff participants will complete the FIM, a 4-item survey, that examines the feasibility of implementing the digitally enhanced peer doula model in routine obstetric settings. Using a five-point Likert scale, the FIM has 4 items examining whether an innovation is implementable, possible, doable, and easy to use. Items are scored using a Likert scale that ranges from 1 (Completely Disagree) to 5 (Completely Agree). Scales are created by averaging responses, with total score values ranging from 1 to 5. Higher scores indicate greater feasibility. Two versions of the FIM will be completed by Site staff participants. The first will collect data on the acceptability of providing smartphones to patients. The second version of the FIM will assess the acceptability of the peer doula component of the model. |

Acceptability of Intervention Measures (AIM)
Zeitfenster: At enrollment (Site staff, Cohort 2), and 30 days post-enrollment (Cohort 1)
|
Site staff and patient participants will complete the AIM, a 4-item survey, that assesses the acceptability of the digitally enhanced peer doula model in routine obstetric settings. The survey asks participants to rate the acceptability of the model from completely disagree to completely agree. Using a five-point Likert scale, the AIM has 4 items examining whether an innovation meets participant approval, is appealing, is welcomed, and is liked. Items are scored using a Likert scale that ranges from 1 (Completely Disagree) to 5 (Completely Agree). Scales are created by averaging responses, with total score values ranging from 1 to 5. Higher scores indicate greater acceptability. Two versions of the AIM will be completed by patient participants. The first will collect data on the acceptability of providing smartphones to patients. The second version of the AIM will assess the acceptability of the peer doula component of the model. Site staff will only complete the second version. . |
