Abstract
Tele-ICU has an off-site command center in which a critical care team (intensivists and critical care nurses) is connected with patients in distance intensive care units (ICUs) through a real-time audio, visual and electronic means and health information is exchanged. The aim of this paper is to review literature to explore the available studies related to efficacy and cost effectiveness of Tele-ICU applications and to study the possible barriers to broader adoption. While studies draw conclusions on cost based on the mortality and Length of Stay (LOS), actual cost was not reported. Another problem in the studies was the lack of consistent measurement, reporting and adjustment for patient severity. From the data available, Tele-ICU seems to be a promising path, especially in the United States where there is a limited number of board-certified intensivists.
