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.
Aim 3: Examine if the E2 intervention reduces racial disparities. Specifically, if the intervention is as effective in racial minorities as non-minorities. This will be an exploratory analysis and will primarily focus on changes in cardiovascular risk score/profile. Also included will be an assessment of intervention mediators: primary care engagement, medication adherence, and HTN knowledge in these same patients at 3 and 6-months post randomization-intervention.

No Intervention: Usual Care
Participants randomized to usual care will receive preprinted discharge instructions on HTN and a 48-72-hour referral to our FQHC (or other community health center if pre-assigned though Illinois Medicaid) to schedule their follow-up appointment (current standard of care)
Active Comparator: Educational and Empowerment Intervention
Other: HTN Educational Video
The video will educate participants in arm 2 about high BP, how it is diagnosed, and the importance of treating it to prevent secondary complications.
Other: Visual Echocardiogram Image Clips
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.
Other: Mobile Health and Remote BP monitoring
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.
Other: Post-Acute Care HTN Transition consultation (PACHT-c)
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.
- Mean systolic blood pressure (SBP) difference at 6 months post-intervention compared to usual care. [ Time Frame: Baseline, 6 months after baseline ]Blood pressure will be collected at two time points (baseline and 6 months). ED-pharmacists and trained research assistants will perform BP measurements using standardized procedures.
- Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) differences at 3 months post-intervention compared to usual care. [ Time Frame: Baseline, 3 months after baseline ]Blood pressure will be collected at two time points (baseline and 3 months). ED-pharmacists and trained research assistants will perform BP measurements using standardized procedures.
- Diastolic blood pressure (DBP) difference at 6 months post-intervention compared to usual care. [ Time Frame: Baseline, 6 months after baseline ]Blood pressure will be collected at two time points (baseline and 6 months). ED-pharmacists and trained research assistants will perform BP measurements using standardized procedures.
- Change in cardiovascular risk score/profile. [ Time Frame: Baseline, 3 months and 6 months after baseline ]
As measured by the Atherosclerotic Cardiovascular Disease (ASCVD) Risk Estimator Plus at baseline, 3 months, and then at 6 months.
Atherosclerotic Cardiovascular Disease Risk Estimator Plus provides a patient's 10-year risk and a lifetime of developing atherosclerotic cardiovascular disease. The 10-year calculated ASCVD risk a quantitative estimation of absolute risk based upon data from representative population samples. The lifetime calculated ASCVD risk represents a quantitative estimation of absolute risk for a 50 year old man or woman with the same risk profile.
The estimator provides risk as a percentage, ranging from 0-100%. A higher percentage is considered a worse outcome.
- Change in medication adherence. [ Time Frame: Baseline, 3 months and 6 months after baseline ]
As measured by the Morisky Medication Adherence Scale at baseline, 3 months, and then at 6 months.
The 4-item Morisky Medication Adherence Scale (MMAS-4) is a validated instrument to assess self-reported patient adherence related to antihypertensive medication. The modified Morisky scale provides a total score with a range of 0 to 4, with higher scores indicating lower adherence to medication. The scores of the modified Morisky scale can be classified as low compliers (3-4), medium compliers (1-2) and high compliers (0) based on its criterion validity with BP control. A higher score on the scale is a worse outcome.
- Primary care engagement. [ Time Frame: 1 month after baseline ]Measured by compliance with outpatient follow-up appointment at 1 month after baseline.
- Change in hypertension knowledge. [ Time Frame: Baseline and 6 months after baseline ]
As measured by a validated HTN knowledge survey at baseline and then at 6 months.
The hypertension knowledge survey is a 10-item, validated tool developed to assess hypertension knowledge in low literacy patient populations. The scale assesses respondents' knowledge in defining hypertension, lifestyle, and behaviors that may affect BP levels, and the long-term consequences of HTN. The survey has been validated in an urban population that included a high proportion of black and Latino patients. Scores are categorized into tertiles that indicate low (≤7), medium (8), or high (9-10) levels of HTN knowledge. The tool comes from: Shane S, Muntner P, Kawasaki L, Hyre A, DeSalvo K. Hypertension Knowledge Among Patients from an Urban Clinic. Ethnicity & Disease. 2008; 18: 42-47.
