Descriptive Information
Brief Title  ICMJE Retail Outlet Health Kiosk Hypertension Trial
Official Title  ICMJE Retail Outlet Health Kiosk Hypertension Trial
Brief Summary The investigators propose to conduct pilot studies to support an application to conduct a fully powered randomized trial of a text messaging intervention to increase the rate of blood pressure control, defined as <140/90 mmHg, among hypertensive individuals using health kiosk blood pressure devices. These pilot studies will include testing of the intervention, recruitment, enrollment, and data collection procedures, and of the web-based interactions between the data coordinating center and higi Sh llc (Chicago, IL), which is the company that installs and maintains the health care kiosks and associated software infrastructure. Completion of these pilot studies will provide preliminary data to support an application for a full scale randomized controlled study. Potential for adaption is high because of alignment of retail outlets, kiosk providers, and consumers for health, wellness, and self-care.
Detailed Description Cardiovascular disease (CVD) remains the leading cause of death in the U.S. as well as the leading cause of health care cost. Hypertension is the leading remediable risk factor for CVD in the U.S. and globally, with prevalence of 29% in U.S. adults. Recent data from NHANES indicate that blood pressure (BP) is not controlled, defined as <140/90 mmHg, in 48% of individuals in the U.S. with hypertension. Strategies to improve hypertension control have focused on the physician-patient interaction at the office visit, system factors in the health care provider system, and extension beyond the traditionally defined health care system. All have had some success but are limited by not reaching individuals outside the clinical encounter or by challenges of scale, scope, and standardization of blood pressure measurement outside the clinical setting. Retail outlet BP devices have the potential to address these limitations by providing free BP measurements to individuals outside the clinical setting and at all times the retail outlet is open. These automated devices are standardized and linked to software with the ability to collect data and provide information to individuals using these devices, thereby providing a platform for an intervention strategy. Higi is a privately owned company that provides health kiosks in retail outlets. Higi presently has 10,800 kiosks in the U.S. with 4,125 in Rite Aid pharmacies. More than 44 million BP measurements per year are obtained at higi kiosks. In the one-year period 7/1/15 to 6/30/16, approximately 727,000 individuals using higi kiosks recorded >3 systolic BP measurements >140/90 mmHg. The investigators propose to target this group using interactive text messaging to activate individuals to take actions to improve BP control. The primary endpoint will be BP control defined as <140/90 mmHg at 12 months post randomization.

Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Condition  ICMJE Hypertension
Intervention  ICMJE Behavioral: Text messages

Study Arms  ICMJE
  • Experimental: Intervention
    Subjects randomized to intervention will receive text messages to promote seeking care and improving compliance with blood pressure treatment.
    Intervention: Behavioral: Text messages
  • No Intervention: Control
    Subjects randomized to the control arm will receive the messages regarding their kiosk blood pressure levels currently provided by higi to kiosk users. These messages are provided at the kiosk at the time of the blood pressure measurement (no text messages).
