Researchers at Northeastern University have developed a virtual nurse and exercise coach that are surprisingly likable and effective—even if they're not quite as affable as the medical hologram on Star Trek. In fact, patients who interacted with a virtual nurse named Elizabeth said they preferred the computer simulation to an actual doctor or nurse because they didn't feel rushed or talked down to.
A recent clinical trial of the technology found that Elizabeth also appears to have a beneficial effect on care. A month after discharge, people who interacted with the virtual nurse were more likely to know their diagnosis and to make a follow-up appointment with their primary-care doctor. The results of the study are currently under review for publication.
