This is a single site, single-blinded parallel randomized control trial that investigates a multi-level intervention to improve postpartum blood pressure in women with hypertensive disorder pregnancy. The investigators will recruit women diagnosed with a hypertensive disorder of pregnancy, identified between 3rd trimester and 2 weeks post-delivery. The investigators will randomize participants to receive usual care home blood pressure monitoring for 6 weeks versus an intervention of usual care + blood pressure and weight monitoring + a doula trained in heart health. This trial will be conducted in partnership with a local community-based organization, Healthy Start Inc.
The purpose of this study is to improve blood pressure in women who have a hypertensive disorder of pregnancy. A hypertensive disorder of pregnancy is one in which a woman's blood pressure is elevated during pregnancy. For the purpose of this project, a hypertensive disorder of pregnancy includes gestational hypertension, preeclampsia and eclampsia. By improving blood pressure in pregnant women, the investigators aim to lower the number of women with chronic hypertension, cardiovascular disease, and mortality. The study will enroll 454 women who are 18 years or older, are about to or have recently given birth, and have been diagnosed with a hypertensive disorder of pregnancy. Women will be randomly chosen to take part in usual care or an intervention group.
This study is designed to evaluate support for new moms by providing a postpartum doula in partnership with Healthy Start Inc. Healthy Start is a local community-based organization that supports women, children, fathers, families and communities through community-based programming, advocacy, research, and training. The support provided to new moms will include weekly doula sessions (in-person or virtual), education and support, and blood pressure and weight monitoring. Women will be enrolled during their third trimester up until they are a few weeks postpartum and will complete the study around 12 months postpartum. If assigned to the intervention group, women will attend weekly check-ins with their doula for 8-12 weeks and receive continuous blood pressure and weight monitoring throughout the duration of the study. Both groups will be enrolled into a 6-week home-based blood pressure monitoring program with text messaging support (enrollment in the 6-week program is the standard of care at Magee Women's Hospital following a hypertensive disorder of pregnancy). Both the usual care and intervention groups will attend a follow-up visit at 12 months postpartum.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Usual Care Group | Active Comparator | The usual care group will receive remote blood pressure monitoring for approximately 6 weeks via the clinical home blood pressure monitoring program at Magee Women's Hospital of UPMC and be discharged after delivery as usual. This monitoring is standardly offered to women post-delivery with hypertensive disorders of pregnancy. Participants will text in their blood pressures to the medical record systems and be monitored by clinical staff. |
|
| Postpartum Doula Intervention Group | Experimental | The intervention group will receive study devices (blood pressure cuff, scales, etc.) and instructions on 10-12 months of remote blood pressure, and weight monitoring. An electronic referral will be sent to the Healthy Start program to initiate postpartum Doula support for 8-12 weeks, and a Doula moderated social support group for 6 months. The postpartum Doula will deliver a heart health focused intervention aimed at reducing blood pressure by approximately 12 weeks postpartum. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Heart Health Doula Intervention Program | Behavioral | The intervention group will be given a smart blood pressure cuff and a smart scale to monitor weight. The intervention group will receive support provided a postpartum doula until 8-12 weeks postpartum. The doula will provide individualized support during this time, and after 8-12 weeks, women will transition to a doula-moderated support group for the remainder of the study. The intervention group will continue to receive blood pressure and weight monitoring for the remainder of the study. |
| Measure | Description | Time Frame |
|---|---|---|
| Assess MAP at 12 months postpartum | To test the effectiveness of the postpartum Doula intervention the investigators will evaluate blood pressure and mean arterial pressure (MAP) at 12 months postpartum. | Baseline to approximately 12 months postpartum |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in racial disparities and blood pressure & MAP at 12 months | To determine if an enhanced care strategy reduces racial disparities in blood pressure, the investigators will evaluate blood pressure and mean arterial pressure (MAP) recovery by 12 months postpartum by race and by intervention group. Systolic and diastolic blood pressures will be assessed separately. There is evidence that blood pressure should normalize at 6-12 months postpartum and by assessing black vs white differences, the investigators will determine if the intervention can reduce known disparities in blood pressure and MAP. |

Deidentified data (including data dictionaries) will be shared at the direction of the primary investigator. Data will include blood pressure, weight, demographics, physical activity, and pregnancy related information. Additional documents (such as the study protocol) will be made available. The dataset for our project will be prepared according to requirements for and stored on the Clinicaltrials.gov data repository. Per the NIH guidelines, the dataset will be submitted to the program officer within a year after the outcomes are published and no later than 3 years after the end of clinical activities.

The investigators will conduct a prospective single site, single-blinded, parallel randomized control trial in which women diagnosed with HDP will be randomized into either the control or intervention group. The investigators will randomize 454 women into usual care, or an 8-12-week heart health intervention program provided by a postpartum Doula. Randomization will be stratified by race to achieve over enrollment of Black and African American participants.

| Usual Care | Behavioral | Usual care includes enrollment into a clinical 6-week home-based blood pressure monitoring program with text messaging support which includes receiving a home blood pressure cuff. Women in the intervention group will be offered the same support as the usual care group, and in addition will receive the intervention and supplies. |
|
| Baseline to approximately 12 months postpartum |
| Assess Racial Disparities in Healthcare Delivery | Access to optimal clinical care is essential for all women to successfully recover from a hypertensive disorder of pregnancy (HDP) within one year postpartum. The investigators will assess racial differences in healthcare service delivery that contribute to inequities in HDP-related care by reviewing the charts of women who enroll in the study and comparing whether care was received, and the type of care aligned with the guidelines/standards by indicating whether the care met, did not meet, or exceeded the standards at critical time points. | Up to 12 months postpartum |
