Feasibility Study of an Integrated Diagnostic System to Manage Heart Failure (INDICATE HF)

This study has been completed.
Information provided by (Responsible Party):
Medtronic Cardiac Rhythm and Heart Failure Identifier:
First received: January 8, 2010
Last updated: April 13, 2012
Last verified: April 2012
The purpose of this clinical trial is to evaluate the potential benefits of a new heart failure diagnostic system for heart failure patients with implanted cardiac resynchronization therapy devices. This system consists of patient tools, a new heart failure risk score and a new clinician website. This study will evaluate this new system as a whole and establish the feasibility of implementing it into clinical practice.

Condition Intervention

Other: Integrated diagnositic system
Other: Routine in office visits

Study Type: Interventional

Primary Outcome Measures:
  • Change in subject self-care utilizing the Self-Care of Heart Failure Index [ Time Frame: Baseline, 3 months, 6 months, 9 months ]
  • Proportion of time clinician and subject complied to protocol requirements for the new heart failure diagnostic system (patient tools and HF clinician website) [ Time Frame: Baseline to 9 months ]
  • Number of clinical actions and types of health care utilizations in which actions are initiated [ Time Frame: Baseline to 9 months ]
  • Subject outcomes including emergency room (ER) visits, hospitalization and death [ Time Frame: Baseline to 9 months ]
  • Functional class using measurements including 6-minute hall walk and New York Heart Association class [ Time Frame: Hall walk (Baseline to 9 months), NYHA (Baseline, 3 months, 6 months, 9 months) ]
  • Quality of life and depression scores utilizing measures including the Minnesota Living with Heart Failure Questionnaire and Patient Health Questionnaire [ Time Frame: Baseline, 3 months, 6 months, 9 months ]

Enrollment: 136
Study Start Date: March 2010
Study Completion Date: February 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Control Arm Other: Routine in office visits
Heart failure will be managed with scheduled in-office visits every three months.
Experimental: Integrated Diagnostics Arm Other: Integrated diagnositic system
Heart failure will be managed using the integrated diagnostic system which consists of patient tools and a new Heart Failure Clinician's website which displays a new Heart Failure Risk score. This Heart Failure Clinician's website will be reviewed every 2 weeks in addition to scheduled in-office visits every three months.
