DOCTORS are to implant computerised sensors into patients to enable
them to monitor chronic conditions minute-by-minute from miles away.

The sensors detect tiny changes in metabolism and transmit data, via a
mobile phone, to the patient's doctor.

Scientists at Imperial College London who invented the device believe
it will enable some patients to lead a normal life while being kept
under constant watch.

It has the potential to be developed into a complete body sensor that
could be implanted into normally healthy people to pick up early signs
of disease.

The sensor, which includes a Pentium microprocessor just 2mm square,
will initially be implanted in diabetics. Trials will begin by
Christmas at St Mary's hospital, London. The implant will be
programmed to send an emergency text message via a mobile phone,
alerting medical staff to changes in blood-sugar levels.

If the problem is serious, the patient will be given immediate medical
advice. Once patients become familiar with the system, they could
monitor their condition themselves.

The only restriction is that the computer's low power output means
that it needs a receiver -- generally a mobile phone -- to be within a
metre of the patient to pick up the sensor's wireless signal from its
miniaturised antenna.

Chris Toumazou, director of the Institute of Biomedical Engineering at
Imperial, is hoping eventually to link the sensor to an insulin pump
that can be operated remotely by a doctor. The sensor could also be
used to protect people with heart and respiratory diseases. The
researchers are exploring ways to detect chemical changes in a
patient's blood.

"The computer in your body can take away anxiety and allow medics to
take control of your care from miles away," said Toumazou.

More than 17.5m people in Britain have one or more chronic diseases of
varying severity -- a figure that is set to soar as the elderly
population grows over the coming decades. If many of these patients
could be turned into experts monitoring their own conditions with
minimal intervention by doctors or nurses, it could free up
significant NHS resources.

The aim is also to develop the system so that the sensor can provide
prompts to patients to take medication.

Pathology departments are under particular pressure because of the
increase in the number of chronically ill patients who need regular
blood tests.

Oracle, the technology company that is backing the project, has
designed the software to be compatible with the NHS's new £6.5 billion
computer system.

This will allow the data to be stored on a patient's record and
accessed by healthcare staff nationwide.

Jeremy Nettle, the European healthcare director of Oracle, said:
"These devices are going to give patients who have to make regular
visits to GPs and nurses much greater control and independence."

He added: "Our aim is eventually to get the cost of each sensor down
to £1 so that the technology is available to everybody."

The Imperial team has developed four other prototypes that rest on a
patient's skin. They include sensors to detect heart disease, high
blood pressure and hypothermia and motion sensors, used to monitor
housebound old people.

Scientists in America implanted microchips containing medical records
under the skin of human guinea pigs last year. The records could then
be read by a doctor using a scanner.

Another American company has placed a microchip on a pill bottle,
which plays back spoken prescription advice through a speaker.

[...]

Before crime can be prevented the monitor must know what the subject
is doing or is about to do....  Moreover, since the incoming data will
eventually be fed into a computer, it will be necessary to confine the
information transmitted to the computer to such non-verbal, non-visual
data as location, EEG patterns, ECG patterns and other physiological
data.

Footnote: Obviously, no system monitoring thousands of parolees would
be practical if there had to be a human monitor for every monitored
subject on a 24-hour-a-day, seven-day-a-week basis.  Therefore,
computers would be absolutely necessary.
