The thing most people don't realize is going digital does NOT necessarily save money or time for the local staff, but it does force conformity that lessens the chance of a misunderstanding or a lack of information when sharing a health record. It can also make tracking who has had access to your information more or less automatic.
If set up correctly:
The big advantage will be to large medical facilities where mutiple staff can access the same medical record from different locations doing different functions at the same time... The main advantage to small practices will be the ability to bill insurance companies faster, as procedures performed will already be in in the record in a standard form... Insurance companies will see less fraud...
Of cource, this is a big "if"...
The key will be defining the "mobile" medical record format... It really doesn't matter what form the data in local databases takes, as long as the local databases can import and export the yet to be defined "standard", as opposed to the mutiple, often conflicting standards already out... Until a single standard is selected and followed, most advantages just won't exist.
