Home Monitoring for Heart Failure Management

from JACC (Journal of the American College of Cardiology):

A new state-of-the-art paper: Home Monitoring for Heart Failure Management

Abstract:
With a prevalence of 5.8 million in the United States alone, heart failure (HF) is a common syndrome associated with substantial morbidity, mortality, and healthcare expenditures. Close to 1 million HF hospitalizations occur annually in the United States, with the majority of these resulting from worsening congestion in patients previously diagnosed with HF. An estimated $37.2 billion is spent each year on HF in the United States. These statistics emphasize the need to develop and implement more effective strategies to assess, monitor, and treat HF. It has also become increasingly apparent that interventions geared toward identifying and monitoring subclinical congestion would be of value in the home management of chronic HF. Earlier identification and treatment of congestion together with improved care coordination, management of comorbid conditions, and enhanced patient self-management may help to prevent hospitalizations in patients with chronic HF. Such home monitoring extends from the promotion of self-care and home visitations to telemedicine and remote monitoring of external or implantable devices. This paper discusses the challenges in monitoring patients with HF, reviews clinical trials testing different monitoring strategies in HF, and highlights ongoing investigations into the optimal approaches to home monitoring for HF.

Fall Monitoring Device Could Help Keep Seniors Safer

from ScienceDaily: 

It's a scenario played out all too frequently: Adult children, worried about the safety of their aging parents, foist devices on them to monitor their safety. And their parents, resentful of having their privacy invaded and losing their independence, resist fiercely.

Now a team of researchers at the University of South Carolina has developed and is testing a simple, innovative program that might just end such standoffs -- and create a safer environment for seniors.

Lead USC researcher Juan Caicedo has taken standard sensors that monitor bridge safety and developed an algorithm that can detect and possibly prevent falls by sensing vibrations associated with an individual's movement. The matchbox-sized sensors, which are placed on a floor or a baseboard of a room, can detect any movement or vibration and then transmit them to a nearby computer.

"The beauty of the program is that it does not use cameras or microphones, so it is a lot less intrusive," Caicedo, a professor of civil engineering, said. "Someone can't listen to what you are saying or see inside your home. Although sensors are not new, the innovation is in how the different signals are processed."

"In this case, the program detects the vibrations, (a possible fall), the exact spot of the vibrations and then estimates the force of impact of the object hitting the floor," Caicedo said. "It can identify the impact of a small ball bouncing or the weight of an adult."
