Doctors have been slow to adopt new technology because medicine is very complex and there is a lack of industry standards. Computerized systems are very expensive and it's hard for some medical centers to come up with the excessive capital. The proponents of IT need to provide to the medical community the information that computerized order entry can be more efficient. Another importance of IT in medicine involves tracking errors. There needs to be a system similar to OSHA and NTSB so patterns of errors can be tracked.
Computerized systems can be invaluable to the medical community, but it needs to be user-focused.
A system that is not user-friendly will not gain the acceptance of the medical community. Medical centers that have lagged behind in technology may find that they have no choice, but to accept new IT innovations. Many other industries have learned to use technology as a tool to set up systems and prevent errors. Health care isn't yet in the same boat.
