Research

Most of what is written about telemedicine is advocacy or sales. This section is the other thing: what the evidence says, where it comes from, and where it is thin.

Does it save money?

The honest answer is that it depends what you count. Telemedicine cost-effectiveness walks through the major studies, the differences between payer savings, system savings, and patient savings, and why the same program can look like a bargain from one seat and a cost from another. It is the guide to read before anyone quotes a savings number in a meeting.

Who gets left out?

Telehealth usability covers accessibility and the digital divide: broadband, devices, language, disability, age, and the design decisions that decide whether a platform works for the people who need it most. Virtual care that only works for people who already had good access is not an expansion of care. It is a redistribution.

What the rest of the world does

Telemedicine around the world is a country-by-country look at how national systems have built, regulated, and paid for virtual care. The United States is unusual in how much of its telehealth policy is set state by state. Seeing how other systems handle licensure and payment is useful context for anyone who assumes the American arrangement is inevitable.

Where all of this came from

The history of telemedicine runs from the earliest remote consultations through the 1990s, when this domain was the online home of Telemedicine Today magazine, to the pandemic and the current AI moment. It is here partly because the history is interesting and partly because most current debates about telehealth were had, in nearly the same words, thirty years ago.

How these guides handle evidence

Statistics are attributed to a named source and rounded. If a number cannot be traced to an organization or a study, it is not on the page. Where the literature disagrees, the guide says so rather than picking the study that supports the nicer story. Where evidence is missing, the guide says that too.

The research guides are updated when major studies or systematic reviews change the picture, not on a schedule. Each page shows its last updated date. If you know of a study that should change one of these pages, send it.
