Want a glance of the future of health care?
Take a look at the way the various networks of people about 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
normal symptoms(症状) are the
most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on real
physiological data(生理数据) from the actual patient. A group from the University of Kentucky
has shown that by using personal data assistance plus a mobile phone, it is
perfectly practical to send a patient’s important signs over the telephone.
With this kind of equipment, 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(countryside) care. And at least one team
wants to use telemedicine as a tool for disaster need-especially after
earthquakes. On the whole, the trend is towards providing global access to
medical data and experts’ opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for
sending complex(复杂的) medical
pictures around the world - CT photos being one of the biggest bandwidth users.
Communication satellites may be able to deal with the short-term needs during
disasters such as earthquakes or wars. But medicine is looking towards both the
second-generation Internet and third-generation mobile phones for the future of
remote medical service.
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 start a new time when
telemedicine and the sharing of medical information, experts’ opinions and
diagnosis are common.
