Default BP Medication Intensification

January 30, 2017 updated by: Florian Rader, MD, MSc, Cedars-Sinai Medical Center

Automatic Medication Increase Protocol in the Treatment of Elevated Blood Pressure

High blood pressure leads to heart attacks and strokes which can be prevented by blood pressure-lowering medication. However, the current office-based prescription of one pill and one dose at a time is ineffective. the investigators want to pilot-test a more effective patient-centered treatment approach, where patients will receive a prescription with gradual but automatic weekly increases of dose and number of pills. Patients will measure their blood pressure with an iPhone compatible cuff, which transmits readings to the doctor or pharmacist, who will stop escalation when the desired blood pressure level is reached. The investigators hypothesize that the intervention will decrease the time to control blood pressure and increase the overall rate of blood pressure control. Therefore, this new treatment model could prevent heart attacks and strokes, and reduce healthcare costs.

Detailed Description

This is a pilot 2A trial of an innovative behavioral economics theory-based antidote for physician inertia in the medical treatment of hypertension (HTN). In the current reactive physician-centered model, blood pressure (BP) is measured and medical decisions are made in the physician office; when deciding whether or not to prescribe new medication for a high office BP reading, the physician's default behavior is inaction. The investigators propose default medication intensification as a new patient-centered/pharmacist-assisted proactive treatment model to eliminate physician inertia. For enrolled patients with office BP>155/95, the physician will prescribe a one-month protocol that automatically escalates drug dose and drug number each week. The pharmacist will fill the prescription in a blister pack to simplify adherence. The patient will measure daily home BP with an iPhone cuff that transmits the data electronically to the pharmacist, who will halt the protocol if goal home BP<135/85 is achieved ahead of schedule. the investigators will pilot test the feasibility and safety of self-monitoring plus the new automatic intensification protocol packaged in blisters. Default medication intensification could revolutionize HTN treatment and reduce healthcare costs.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: default intensification arm (all)
all subjects will receive blister packs with weekly increasing blood pressure medications. There is no control arm for this study
Other: default intensification
The investigators will determine which blood pressure medications to use. No specific drug will be tested but rather the automatic intensification of medications is the intervention. Examples of drugs used in this study are calcium channel blockers (e.g., amlodipine 2.5 mg to 10 mg) or ACE-inhibitors (e.g., lisinopril 5 mg to 40 mg) or diuretics (HCTZ 25 mg).
Other Names:
  • weekly increasing blood pressure medications.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Symptomatic hypotension
Time Frame: from enrollment to 12 weeks
Primary safety outcome is symptomatic hypotension during study participation (12 weeks). Safety monitoring will be achieved with patient-directed iPhone-based BP measuring and transmitting to study staff.
from enrollment to 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
hypertension control rate
Time Frame: at 12 weeks
The investigators will assess blood pressure throughout the study period (12 weeks) with iPhone based technology. Hypertension control is defined as home blood pressure <135/85 mmHg
at 12 weeks
