The once-in-a-century pandemic has changed the world in many ways. In the U.S., which suffered the most damage, people were forced to use non-contact medical care, especially in the medical field, and as a result, various medical devices and services using digital technology became a MUST HAVE and spread rapidly. Now that the corona disaster is over, we are not going back to the pre-corona state, but rather, a hybrid of virtual and physical medicine is being developed. For example, telemedicine accounts for more than 50% of family physicians’ practice, and U.S. health insurance authorities actively promote day surgery. In addition, the concepts of Virtual Hospital and Medical Home are being introduced to provide hospital inpatient care at home and will be reimbursed by the U.S. health insurance authorities in the fall of 2021. In this way, digital medical transformation using digital technology is advancing rapidly, necessitated by the Corona disaster, and the fourth industrial revolution is taking place in both name and reality. In this article, I would like to introduce the current status of digital technology in the U.S. medical industry.
