BP PAL - Hypertension Chat Bot Pilot

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.
