No one likes being in the hospital. Given a choice, virtually everyone would prefer to be treated at home. This is especially true for older adults. At the same time, preventable hospital readmissions cost the Medicare program billions of dollars every year. Now new, easy-to-use technology is helping home health services to daily monitor the health of their patients, with the patients themselves daily collecting essential data. This same technology also contributes to patient and caregiver "peace of mind."
