Emergency rooms in rural areas don't see many very sick or badly injured children each year. When they do, bringing in a pediatric critical care specialist by videoconference to help with treatment could prevent errors, a new study suggests. Researchers found rural ER doctors made errors in administering medication - such as giving the wrong dose or the wrong drug altogether - just 3 percent of the time when they used so-called telemedicine to connect with a specialist. That compared to an 11 percent error rate when local doctors talked with a specialist by phone and a 13 percent error rate when they didn't consult with a specialist at all.
