In the recent few decades, medicine and health care in the whole world have been revolutionized and improved, as they are based on the increasingly intensive use of information and communication technologies, whose rapid development brings a number of innovative solutions and the transformation in the way of providing all services, as well as those in health care. One of the most significant innovations in the new digitalized health care is telemedicine – »remote health care« performed by exchanging data through information and communication technologies, and enabling greater quality and equal access to health care for everyone, especially considering the population of distant, isolated and areas which are difficult to reach. In this paper, I wanted to highlight the concept, the meaning and the basic characteristics of the telemedicine activities as one of the public sector innovations in the treatment and health care, by defining the term, the importance and the types of telemedicine, the conditions and the manner of performing the telemedicine services in certain medical specialties. Further more, I wanted to define the most important telemedicine achievements, with particular emphasis on telemedicine of the health care system of the Republic of Croatia, which is the basis of this paper. As the public sector conducts innovative activities with the aim of raising the value of public goods, meeting the social needs and improving the life quality for citizens, I wanted to demonstrate that the implementation of telemedicine in the health care system of the Republic of Croatia is a successfully implemented innovation.
