Plain English summary of protocol

Background and study aims
More heart failure patients now receive device-based treatment in the form of implantable cardioverter defibrillators (ICDs) and cardiac resynchronisation defibrillators (CRT-D), but despite this, admissions and healthcare costs relating to heart failure continue to rise. Recent device technology that transmits data from an implanted cardiac pacing device to a monitoring station in the home can predict left ventricular heart failure deterioration. The aim of this study was to evaluate the relative costs and the acceptability of conventional and remote care pathways designed to monitor implanted device technology for chronic disease in the home.

Who can participate?
Heart failure patients over 16 years old with implanted ICD/CRT-D devices.

What does the study involve?
The remote monitoring group (consisting of patients with implanted Medtronic devices with the Optivolâ„¢ intrathoracic impedance feature) were compared with control patients implanted with devices that did not have access to remote monitoring and who followed the usual standard pathway of care. The remote monitoring group were further randomly allocated into two groups, either remotely downloading daily for three months and then weekly for three months, or downloading weekly for the six-month period. The downloads were reviewed on the day of download by the study nurse, who reported to the consultant responsible and made medication or programming changes where required.

What are the possible benefits and risks of participating?
There are no disadvantages or risks as the care will be the same whether the volunteer chooses to participate or not. It is hoped that the results may help us develop better ways of preventing hospital admissions for heart pump failure and heart rhythm abnormalities in the future.

Where is the study run from?
Southampton General Hospital (UK).

When is the study starting and how long is it expected to run for?
The study ran from February 2009 to August 2009.

Health condition(s) or problem(s) studiedTopic: Cardiovascular; Subtopic: Cardiovascular (all Subtopics); Disease: Cardiovascular
Intervention6 month study of two groups.

Group 1:
Observation so diary entry and Quality of life questionnaires only.

Group 2 (interventional):
Study group download from device using Carelink. Divided into A and B:
Group A: daily downloads for three months and then weekly for remainding three months
Group B: weekly download for the whole duration - six months

Based on the information obtained from the downloads will determine if treatment needed to be changed - i.e., medication or programme changes to device.

Follow up length: 0 months
Study entry: Other
Intervention typeOther
Primary outcome measureQuality of Life is measured uisng the Living with Heart failure Minnesota Life Score and 36-item short form health survey (SF-36) at baseline, 1, 3 and 6 months
Secondary outcome measuresNo secondary outcome measures
