Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another , and how this new connectivity is being exploited to deliver medicine to the patient — no matter where he or she may be .

Online doctors offering advice based on standardized symptoms are the most obvious example . Increasingly , however , remote diagnosis (telemedicine) will be based on real physiological data from the actual patient . A group from the University of Kentucky has shown that by using an off-the-shelf （现成的） PDA (personal data assistance) such as a Palm Pilot plus a mobile phone , it is perfectly feasible to transmit a patient's vital signs over the telephone . With this kind of equipment in a first-aid kit （急救包 ） , the cry asking whether there was a doctor in the house could well be a thing of the past .

Other medical technology groups are working on applying telemedicine to rural care . And at least one team wants to use telemedicine as a tool for disaster response — especially after earthquakes . Overall , the trend is towards providing global access to medical data and expertise .

But there is one problem . Bandwidth is the limiting factor for transmitting complex medical images around the world — CT scans being one of the biggest bandwidth consumers . Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes , wars or famines . But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence .

Doctors have met to discuss computer-based tools for medical diagnosis , training and telemedicine . With the falling price of broadband communications , the new technologies should usher in （迎来） an era when telemedicine and the sharing of medical information , expert opinion and diagnosis are common .
