Hypertension (HTN)REACH BPNCT07127731
REmote Physical ACtivity Intervention for High Blood Pressure Postpartum
A study testing Patient Portal Messaging and FitBit EHR Linkage in people with Hypertension (HTN) and Hypertension ,Pregnancy, run by Northwestern University.
Trial summary
The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. Read more about this study

About this study
Official title: REACH BP: REmote Physical ACtivity Intervention for High Blood Pressure Postpartum
The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. The investigators will test if the intervention improves step counts and blood pressure after pregnancy. The investigators will also test if the intervention is feasible and enjoyed by postpartum women.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Patient Portal MessagingBehavioural
Participants will receive weekly messages via their patient portal including feedback on their step counts and step count goals based on data from their FitBits
FitBit EHR LinkageBehavioural
Participants will receive FitBits and link this step count data with the Electronic Health Record (EHR)
| Study group | Role | What they receive |
|---|---|---|
| Experimental Group | Experimental | Not described Receives: Behavioral: Patient Portal Messaging; Behavioral: FitBit EHR Linkage |
| Control Group | Active comparator | Not described Receives: Behavioral: FitBit EHR Linkage |
What is being measured
The primary outcome is the main question the study is designed to answer.
Feasibility of Recruitment
Number of participants enrolled in the intervention
Measured: From enrollment to the end of the 24 week intervention
Feasibility of Participant Retention
Percent of enrolled participants who continue to participate in the intervention
Measured: At study weeks 12 and 24
Feasibility of FitBit+EHR linkage
Percent of intervention days FitBit data are linked to the Electronic Health Record
Measured: From enrollment to the end of the 24 week intervention
Feasibility of Intervention Messaging
Percent of weekly messages that are read by participants
Measured: From enrollment to the end of the 24 week intervention
Acceptability of the Intervention
Participants will fill out a survey to assess the extent to which they were satisfied with individual intervention components including FitBit usage, portal messaging, blood pressure and weight assessments, surveys, intervention length and intervention delivery. Each component will be rated on a 5-point Likert Scale in which 1 represents very dissatisfied (lowest score) and 5 represents very satisfied (highest score).
Measured: Study week 24
