Doctors to store info under your skin.

Doctors could soon be storing essential medical information under the skin of their patients, The American Medical Associations says.

Devices the size of grain of rice that are implanted with a needle could give emergency room doctors quick access to the records of chronically ill patients.

The Association adopted a policy stating that the devices can improve the "Safety and Efficiency of patient care" by helping to identify patients and enabling secure access to clinical information. These radio frequency identification tags are already used by Wal-Mart and other businesses to speed up their shipping systems by sending out small signals that can be scanned more easily than bar codes.

Implanting them in people can improve the continuity and coordination of care with resulting reductions in adverse drug events and other medical errors.
