As the practice is growing there have been studies completed to show the impact of telemedicine on patient outcomes and health care costs. For example in North Carolina, telemedicine is helping aging adults remain in their homes by decreasing hospitalization rates related to heart failure, COPD and diabetes. Patients with these diagnoses were monitored by telehealth technologies at home in between skilled nursing visits. Both response and intervention times increased dramatically.
Have you considered reviewing this --> The Role of Telehealth in an Evolving Health Care Environment: Workshop Summary discusses the current evidence base for telehealth, including available data and gaps in data; discuss how technological developments, including mobile telehealth, electronic intensive care units, remote monitoring, social networking, and wearable devices, in conjunction with the push for electronic health records, is changing the delivery of health care in rural and urban environments. It is important to note however that it is from 2012
Addtionally, while you did not ask about this, I think it is also important to consider the national landscape of telehealth policies that exist right now (including reimbursement) since that will also have an impact on how they are implemented.

I am happy to discuss further.

The concept could potentially apply to elder care, especially for those individuals living in place (versus those in an assisted living facility)...if they have a computer with an internet connection and video capability. Sherpaa is a remote telehealth provider servicing corporate customers and now, individual consumers. They are not targeting elder consumers specifically.

MedaCheck and many other organizations are providing reminder applications for Cell Phone and tablet use. These applications "remind" individuals when it is time to take their medications or perform tasks such as blood pressure or blood glucose monitoring. There are many potential benefits to these types of programs when you consider enhancing their basic functions to include secondary alerting (call a caregiver or family member if the individual fails to respond) or telehealth technology (using webcam to have a conversation with the individual who fails to take their medications.
Additionally, adherence data can be gathered from the back end of these programs that may help health plans and Continuing care communities identify opportunities to improve the staffing level and services being offered for residents.
