Telemedicine uses communications technology to deliver healthcare remotely. There are two main markets: clinical telemedicine between hospitals and clinics, and home telemonitoring. Clinical telemedicine provides expertise to remote areas and has significant costs savings. Home telemonitoring uses simple systems to monitor patients at home to maintain health, independence, and reduce costs. Studies show telehomecare results in improved quality of life, reduced hospital admissions and ER visits, good patient and nurse acceptance, significant cost savings, and better care through more frequent and accurate measurements and communication.
