NCT06842875

Brief Summary

This is a hybrid type 1 non-inferiority implementation effectiveness trial among postpartum patients with hypertension (N=1536) that will test the hypothesis that RI-SPHERES (a technologically enabled collaborative care model) is non-inferior to a standard self-measured blood pressure program in terms of persistent hypertension at six weeks postpartum and preventive care receipt within one year of delivery.

Study Arms (2)

RI-SPHERES

EXPERIMENTAL

A technology enabled collaborative care model. Participants will receive a LTE-enabled blood pressure (BP) cuff that syncs to a smartphone application (app) to send automated reminders and provide adaptive messaging tailored to distinct BP values and symptoms. The first six weeks of the program will focus on BP control, and the remaining time will help transition people to receive recommended preventive care. As part of the collaborative care model, the nurse practitioner will lead weekly meetings with a multidisciplinary clinical team about all enrolled people.

Behavioral: RI-SPHERES

Standard self-measured blood pressure program

ACTIVE COMPARATOR

Our hospital has a remote hypertension monitoring program that recommends daily blood pressure ascertainment for 6 weeks, at which time they are discharged and provided printed resources to encourage preventive care in the next few months. In this program, patients manually enter their self-measured BPs into the electronic medical record for the clinical team to manually review and respond.

Behavioral: Standard self-measured blood pressure program

Interventions

RI-SPHERESBEHAVIORAL

Participants assigned to the RI-SPHERES group will be introduced virtually or in-person to the care manager (CM), who demonstrate how to communicate directly with patients through the app for medical or non-medical needs. Each participant will learn how to obtain SMBP, sync the LTE-enabled BP cuff to the RI-SPHERES app, and respond to adaptive messaging pertaining to BP measurements, which include the ability to receive on-demand education on postpartum topics (e.g., HDP, breastfeeding, mood disorders) per participant preference. During the study period, the CM will respond to needs elicited from the SDoH screening by facilitating referrals to community resources. After six weeks, the focus of RI-SPHERES will transition to preventive care in addition to SMBP. The CM will engage monthly with each study participant to ensure they have a primary care provider and to facilitate preventive care visits or specialist appointments, if needed.

RI-SPHERES

Participants assigned to the routine care group meet virtually or in-person with a member of WIH's existing SMBP program and enroll in WIH's EPIC MyChart Portal to allow the SMBP program to receive patient-entered BP measurements and respond to messages. Participants will be provided with BP cuffs and taught how to obtain SMBP and report their BP through MyChart. At six weeks postpartum, WIH SMBP staff send a MyChart message to recommend BP ascertainment once per month and to describe the importance of attending a clinical visit with a primary care provider within a year of birth.

IPD Sharing
Will share

Data will be collected from human subjects and will be shared according to NIH guidelines. The investigators are committed to the sharing of final data, being mindful that the rights and privacy of people who participate in research must be protected at all times. The investigators will make a complete study dataset available for sharing. The investigators will have a description of study dataset, including code books, meta-data related to the dataset, and documented programming code used for creating the final study population, for creating variables, and for conducting all outcomes analyses. The investigators will remain HIPAA compliant, and therefore any datasets resulting from participants will be free of any identifiers that would permit linkages to individual research participants and variables that could lead to deductive disclosure of individual subjects.

Access Criteria
The investigators will make the data and associated documentation available to users under a data-sharing agreement that provides for commitment to: a) using the data only for research purposes and not to identify any individual participant; b) securing the data using appropriate computer technology; and c) destroying or returning the data after analyses are completed. Timelines for distribution of data will vary depending on any required restrictions as mentioned above. Data may be distributed by a number of electronic methods, including web-based databases, datasets, and spreadsheets, or via electronic media such as compact discs.
