As the population ages and medicine advances, there has been a significant shift to the management of chronic diseases. Most chronic diseases are managed using evidence based consensus guidelines but clinician and patient compliance with these guidelines is sub-optimal. In addition, due to the nature of chronic diseases, patients need to make long-term lifestyle changes in order to effectively control their disease in order to minimize complications, disability and cost. It is these two factors, consistent implementation of evidence-based guidelines and supporting patients in a way that encourages self-management and lifestyle change, that disease management attempts to impact. There are areas of design, implementation, testing and final-result-reporting to the patient and clinician that require collaboration among information technology (IT) and software design engineers and clinicians to achieve several goals:

1. Ensure patient safety.
2. Protect the security and integrity of clinical data.
3. Provide patient specific education to promote self-management.
4. Provide actionable data to clinicians in order to improve clinical care and minimize the risk of adverse events.
5. Provide both patient and clinician satisfaction with the system of care.

In order to achieve these goals, testing and development of home technology under a controlled clinical trial is critical.

This study will consist of: Specific Aim 1, Perform a pilot study to evaluate the initial performance of the wireless scale and symptom monitoring system on a select number of presumed normal volunteers (five). The purpose of this will be to determine design and process changes prior to the use of the device in subjects with chronic heart failure (HF). The investigators will have each normal volunteer (all part of the key research team) perform scenarios to test the performance of the system. Specific Aim 2 will incorporate changes into the prototype system adapting both the technology as well as the clinical workflows surrounding its use based on the information collected in Specific Aim 1. Specific Aim 3 will evaluate the revised system enrolling 40 volunteer subjects that have provided written voluntary consent with the documented primary diagnosis of HF (systolic or diastolic) to participate in the intervention over a 4-month period with the primary outcome measure being reduction in HF related ER visit or hospitalization.

The objective of this study is to pilot test and refine a new home-based telemedicine health monitoring system that provides wireless, low cost measurement of body weight as well as self-reported responses, including symptoms and medication compliance for the purpose of managing chronic heart failure (HF) within the home. This pilot will test the functionality of the research infrastructure first on 5 healthy volunteers and then on 40 patients with heart failure over 4 months, testing the receipt of accurate input from the wireless scale and then assessing the effectiveness of the scale intervention in reducing ER visits and hospitalizations.
