Remote monitoring of patients in intensive care units (ICUs) is not associated with an overall improvement in survival, a new study has found.
Experts suggest that intensive care physicians look after ICU patients onsite because of an associated lower rate of illness and death.
"However, there is a shortage of intensivists, which has led to the use of telemedicine technology to allow intensivists to remotely and simultaneously care for patients in several ICUs (ICU telemedicine [tele-ICU]), thus extending their reach," the authors said.
"Remote monitoring may be a partial solution for the intensivist shortage, but it is expensive, its use is increasing, and there are few data in the peer-reviewed literature evaluating its effect on morbidity and mortality," they added.
Eric J. Thomas, of the University of Texas Health Science Center at Houston, and colleagues assessed the effect of a tele-ICU intervention on mortality, complications, and length of stay (LOS) in 6 ICUs of 5 hospitals in a large U.S. health care system by measuring these outcomes before and after implementation of the tele-ICU.
The study included 2,034 patients in the preintervention period (January 2003 to August 2005) and 2,108 patients in the postintervention period (July 2004 to July 2006).
