A computerized kiosk under development at Massachusetts General Hospital (MGH) can take a patient’s medical history, weight, pulse, blood pressure, and other vital signs, and even perform simple blood tests for glucose and cholesterol. Physicians hope that the device, slated to begin field testing in the United Kingdom in June, will one day bring relief to the overburdened healthcare system, and allow doctors to intervene earlier in chronic disease.
Doctors’ appointments in the United States often feel like more of an inconvenience than a help, both for patients, who can spend hours in waiting rooms, and doctors, who spend hours filling in charts and organizing patient information. Ronald Dixon, director of the Virtual Practice Project, imagines that his kiosk–a small, Windows-based desktop computer with just a few peripherals–could one day revolutionize doctors’ visits just as ATMs transformed banking. By removing the tellers from the interactions that could be easily automated, banks saved face-to-face contact for more complex transactions. Dixon, who’s also a primary-care physician at MGH, believes that the same could be done for doctors.
The kiosk consists of a tabletop computer and a number of peripherals–a blood-pressure cuff, a scale, a pulse oximeter to measure blood oxygen levels, and a peak-flow meter to determine whether someone’s airways are constricted–as well as a blood-testing device commonly used in emergency rooms that can measure cholesterol and glucose levels. (The current version requires a trained assistant to do the finger stick for blood collection, although future versions will be automated.)
