BP PAL - Hypertension Chat Bot Pilot

Study Overview
=================
Brief Summary
-----------------
A 2-arm randomized pilot trial aimed at evaluating the effectiveness of a 6-month remote monitoring program for the management of hypertension (HTN). 300 eligible patients will be randomized in a 1:1 ratio into two recruitment arms: A) Control (usual care), or B) Remote monitoring via automated messaging program. The target population are patients at the Penn Family Medicine University City and Westtown primary care practices with baseline poor blood pressure control as indicated by two blood pressures greater than 140/90 within the past twelve month including the most recent measurement and on at least one anti-hypertensive agent.

Detailed Description
-----------------
STUDY DESIGN: Pragmatic, non-blinded, randomized controlled trial. Randomization and enrollment: Randomization will be at the patient level (stratified/balanced randomization by PCP) Enrollment will take place over short time period based off of lists of eligible patients pulled from the EMR Lists of eligible patients sent to PCPs with opportunity to opt patients out. Patients will be contacted via text followed by phone call to introduce them to the program. We expect recruitment to take approximately 1 month to reach a target sample size of 300. The program itself will be 6 months from the date of randomization. Total study duration should be approximately 7 months. Data analyses will take an additional 3 months. The control group will receive usual care as determined by PCP (control arm will not receive BP cuffs).The Intervention Group will receive the BP cuff and weekly SMS messages asking for the BP reading. The methods section below will outline the details for both groups.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>Patients assigned to intervention arm will a text message notifying them of enrollment, be mailed a BP cuff and receive a recruitment phone call if nonresponsive to text. If the patient does not opt out, the research coordinator will mail a blood pressure cuff and proper measurement instructions and start their remote monitoring program in the Way to Health platform. Intervention arm participants will also receive usual care. Usual care for hypertension is as needed determined by the clinical expertise of the primary care provider and can include regular follow-up visits (in person or virtual), home blood pressure readings, titration of medications during visits or via telephone, referral to specialty care (e.g., Nephrology or Cardiology), blood tests or imaging studies. | Behavioral: HTN Chat bot<br>* Remote monitoring via automated messaging program<br>|
| No Intervention: Control<br>Patients in the usual care arm will not be contacted by study staff at the start of the pilot, they will not receive a blood pressure cuff, and they will not receive any text messaging or any component of the program. They will eventually be contacted by study staff to schedule the 6 month BP check. Usual care for hypertension is as needed determined by the clinical expertise of the primary care provider and can include regular follow-up visits (in person or virtual), home blood pressure readings, titration of medications during visits or via telephone, referral to specialty care (e.g., Nephrology or Cardiology), blood tests or imaging studies. | |
