University of Michigan Advanced Heart Failure Tele-Monitoring and Flexible Diuretic Project

Not Applicable

Terminated

• Conditions: Heart Failure
• Interventions: Device: Telemonitoring; Other: Flexible Diuretic Regimen

• Registration Number: NCT02344342
• Lead Sponsor: University of Michigan

Brief Summary

The proposed project is a 2x2 factorial designed study aimed at assessing the impact of 1) a home tele-monitoring system and 2) a flexible diuretic regimen among high risk heart failure patients in the University of Michigan Health System (UMHS).

Detailed Description

The proposed project is a 2x2 factorial designed study aimed at assessing the impact of 1) a home tele-monitoring system and 2) a flexible diuretic regimen among high risk heart failure patients in the University of Michigan Health System (UMHS). The first intervention consists of the use of a home monitoring tool utilizing a tablet interface. The device facilitates collection of heart failure patient self-care information, including weight, blood pressure, heart rate and heart failure symptoms. This information is collected and stored on a secured server provided by the vendor, and can be viewed by the physician and nursing team. The second intervention is a flexible diuretic regimen strategy. This intervention will be applied in an independent randomized fashion. The flexible regimen will be prescribed by the patient's physician. The two interventions will be applied to heart failure patients treated at the University of Michigan. A total of 400 patients will be enrolled into the study.

Arm && Interventions

Group	Intervention	Description
Health Buddy Web Management system	Telemonitoring	Patients randomized to the telemonitoring intervention will be assigned to use the Bosch Health Buddy Web management system.
Flexible Diuretic Regimen	Telemonitoring	Patients randomized into the Flexible Diuretic Regimen intervention will have a diuretic regimen specified by specific weight ranges.
Flexible Diuretic Regimen	Flexible Diuretic Regimen	Patients randomized into the Flexible Diuretic Regimen intervention will have a diuretic regimen specified by specific weight ranges.
Health Buddy Web Management system	Flexible Diuretic Regimen	Patients randomized to the telemonitoring intervention will be assigned to use the Bosch Health Buddy Web management system.

Primary Outcome Measures

Name	Time	Method
Number of Days Hospitalized or Dead in the 180 Day Follow up Period	180 days (6 months)	This is the total combined number of days that all participants in each arm were hospitalized or dead between day 1 and day 180. It is a method to combine the endpoints of death and hospitalization used in heart failure trials. Days hospitalized for all participants are added to days dead for all participants, per arm.

Secondary Outcome Measures

Name	Time	Method
Self Care for Heart Failure Index Score	180 day follow up	The self care for heart failure index score ranges from 22 to 88 where 22 is the lowest score meaning cares for oneself least well and 88 means one is most confident or able to care for oneself properly.
Minnesota Living With Heart Failure Questionnaire	180 day follow up	It provides a total score (range 0-105, where 0 is best quality of life up to 105 as worst Health Related Quality of Life),
Days to Hospitalization or Death (if it Occurs Within 180 Days)	180 days	Time to Hospitalization (if participant was hospitalized and did not die) or death whichever came first. In fact all participants who died in the follow up period were hospitalized first, so actual data reported below also represents time to hospitalization for all participants.
