Teleconsultation involves the use of technology so that the medical professionals and patients can interact with each other bringing health to where ever it is needed. Although it has been demonstrated to be feasible and effective its sustainability remains an important question. This paper presents the results of a literature review on teleconsultation, based on the Portuguese context. Although Portugal has some successful projects, a national or international conjoint effort would be more fruitful. Technologically it gets lets costly to provide teleconsultation, as pervasive computing grows. The gap of benefits between teleconsultation and regular consultation will diminish as patients grow fonder into technology.The economic value of this type of consultation remains a difficult subject, so a small budget economic analysis, based on a break-even method, is suggested. This analysis conducted on Finland shows that teleconsultation can be cost-effective.
