• Recruitment Status: RECRUITING

• Total Enrollment: 30 participants

Brief Summary

The purpose of this study is to test the proof-of-concept for adding a novel mHealth application, USeeBP, to the established UChicago Medicine Ambulatory Medicine Remote-Patient Monitoring (UCM-RPM) Hypertension Management Program in a population of African American adults with poorly controlled hypertension.

Detailed Description

This is a single-arm, proof of concept study, which we will use to assess for initial evidence of efficacy and technical feasibility of adding the USeeBP mHealth app as an adjunct to the UCM-RPM program.

This study integrates the USeeBP app into the existing UCM-RPM clinical pathway. Regular UCM-RPM program activities include monitoring home blood pressure (BP) measurement flowsheets, performing patient telephone and EPIC MyChart message outreach, and making medication adjustments. USeeBP is a secure, chat-based smartphone application. The app connects to a patient's electronic BP cuff (eCuff) via Bluetooth and sends BP data to the UCM-RPM program (rather than using the companion app to the eCuff that is used in the UCM-RPM program). The USeeBP app also allows the patient to set BP check and medication reminders, as well as provides patient education and opportunities to participate in healthy behavior challenges.

The primary study goal is to measure the effect of the USeeBP mobile app on home BP. Serial home blood pressure measurements will be collected at multiple time points. We hypothesize that there will be a decrease in BP across the study period.

Group Type: EXPERIMENTAL

USeeBP

Intervention Type: OTHER

USeeBP is a low risk mobile medical app that proposes to do no more than:

• Help patients (i.e., users) self-manage their disease or conditions without providing specific treatment or treatment suggestions;
• Provide patients with simple tools to organize and track their health information;
• Provide easy access to information related to patients' health conditions or treatments;
• Help patients document, show, or communicate potential medical conditions to health care providers;
