The proposed project underscores the following: 1) The prevalence of uncontrolled/undiagnosed hypertension (HTN) in underrepresented groups presenting to the ED is alarmingly high, and 2) ED engagement and early risk assessment/stratification is a cost-effective, feasible innovation to help close health disparity gaps in HTN. This proposal involves a two-arm randomized controlled trial of up to 770 patients from the Emergency Department at University of Illinois Hospital with elevated blood pressure (BP). The primary objective is to determine the effectiveness of an emergency department-initiated Educational and Empowerment (E2) intervention with a Post Acute Care Hypertension Consultation (PACHT-c) intervention (arm 2) on the primary outcome of mean systolic blood pressure (SBP) differences between the two trial arms at 6-months post intervention. Secondary objectives include evaluating the effectiveness of this ED education and empowerment intervention on mean SBP and diastolic blood pressure (DBP) differences at 3-months, and mean DBP differences at 6-months.
The study is a single-site randomized controlled trial (RCT) focused on a high-risk ED population with evidence of moderately elevated BP (≥140/90 mmHg) at discharge. ED patients will be recruited and randomized into two arms: 1) usual care (preprinted discharge instructions and 48-72 hour referral to a federally qualified health center (FQHC) or assigned provider as appropriate); 2) ED-initiated E2 intervention program followed by 48-72 hour referral to a FQHC (or assigned health center). Based on the ED population demographics (70% ethnic minorities), the majority of participants will be underrepresented minorities (NHB and Hispanic) and low-income individuals. The investigators propose the following specific aims and hypotheses:
Aim 1: Evaluate the effectiveness of an ED-based E2 + PACHT-c intervention (arm 2) on the primary outcome of mean SBP difference at 6-months post-intervention compared to usual care (arm 1).
H1: The mean SBP difference (from baseline) will be significantly greater in the E2+ PACHT-c group (arm 2) compared to the usual care group (arm 1) at 6- months post-randomization, i.e., SBP change in arm 2 > arm 1 at 6-months post-randomization.
Aim 2: Evaluate the effectiveness of an ED-based E2 intervention with PACHT-c on the secondary outcome of mean SBP and DBP differences at 3-months, and mean DBP differences at 6 months post-intervention compared to usual care.
H2: The mean SBP and DBP differences from baseline to 3- months post-intervention and mean DBP at 6-months post intervention will be significantly greater in the ED-based E2 intervention compared to the usual care group, i.e., SBP and DBP change in arm 2 > arm 1 at 3 -months post-intervention and DBP change in arm 2 > arm 1 at 6 -months post-intervention.

The TOUCHED data sets will be submitted to the NHLBI Data repository, and will include the following:
In the preparation and delivery of the Data to the NHLBI Data Repository, all personal identifiers will be eliminated. A summary of all proposed modifications and deletions to be made to a data set will be submitted to and approved by the NHLBI Data Repository representative prior to their implementation.
The TOUCHED data set will be submitted to the NHLBI Program Officer, no later than 3 years after the end of the clinical activity (final patient follow-up, etc.) or 2 years after the main paper of the trial has been published, whichever comes first.

Research Assistants are blinded to study arm assignment of participant when assessing outcomes measures.
| Visual Echocardiogram Image Clips | Other | Visual clips of age/gender-matched echocardiograms will be used to educate and motivate patients to change their behavior and improve their BP. We have found that real time visualization of cardiac ultrasound images with active discussion of findings is a significant patient motivator and empowerment tool, and was a significant factor in the success of our previous pilot study. |
|
| Mobile Health and Remote BP monitoring | Other | All participants randomized to the intervention group will receive an FDA-approved HBPM kit that includes the Nokia wireless (self-inflating) BPM+ monitor and Health Mate mobile app. The app automatically launches when the patient slips on the cuff and turns on the monitor to measure his/her BP. Synced data are automatically uploaded from the mobile app to the iCardia server of our study. |
|
| Post-Acute Care HTN Transition consultation (PACHT-c) | Other | All participants randomized to the E2 intervention will have a focused consultation with either a clinical pharmacist or an APN. During this consultation, the pharmacist/APN repeats the BP measurement; reviews the screening assessments; and reviews general principles of BP control including nutrition, exercise, and smoking cessation. BP will be managed according to the current published guidelines available at the time of funding regarding initiation of first-line antihypertensive medications. Patients with BP ≥160/100 mmHg may be started on antihypertensive medications by the provider during the consultation if appropriate. |
