CHF Management Using Telemedicine

Improving CHF Outcomes Through Interactive Voice Recognition (IVR) Data Acquisition and Targeted Nurse Follow-Up

The overall objective of this study is to improve clinical outcomes and quality of life for congestive heart failure (CHF) patients by integrating a readily available, low cost technology - the telephone - into coordinated CHF care.

Strong patient-provider communication and vigilant home-based monitoring can be critical elements of successful chronic disease management. Among CHF patients, automated clinical data acquisition via the telephone can improve insight into inappropriate use of medications and onset of fluid overload or edema - indicating deteriorating heart function (notably worsening ejection fraction). Routine, timely monitoring of this data can direct a nurse case manager to the subset of CHF patients likely to benefit from a clinic visit, evaluation, diagnosis, and counseling. This should result in: significantly increased medication compliance, significantly lower emergency department (ED) visits and hospital admissions (both those related to CHF and other conditions related to diminished physical capacity of patients with CHF), and improved physical function. This study is intended to answer three questions. First, do potentially avoidable acute events (measured by ED visits and hospital admissions) decrease when CHF management is accompanied by systematic telephone-based monitoring as compared with usual care? Second, does medication compliance improve when CHF management is accompanied by systematic telephone-based monitoring as compared with usual care? Third, does perceived health status (physical and emotional function) improve when CHF management is accompanied by systematic telephone-based monitoring as compared with usual care?
