Remote patient monitoring devices that track patient data and send it to doctors can help patients better manage their conditions. Half of US hospitals now use telemedicine. One remote patient monitoring program saw a 75% reduction in hospital readmissions. The cost of healthcare in the US is expected to rise significantly by 2020 and 2030, but increased use of remote patient monitoring may save $200 billion over 25 years by improving care, enhancing patient satisfaction, and reducing costs.
