The really useful low hanging fruit of EHR is an electronic portal for radiology results, blood results, discharge summaries and letters. If you have a way to link family doctor/pharmacy prescriptions with hospitals, thats great too.
My ideal health IT system assuming perfect AI and everything else would be:
- Automatic recording of everything discussed and done between nurses/doctors with no input from the doctor and producing a record which reads in a sensible way
- Automatic prompting for things the doctor/nurse was likely missed or should discuss during a consult (but only to a sensible level of detail)
- Automatic checking for common ommissions, or things that are being done that perhaps shouldn't be, so a patient who has a microcytic anaemia triggers a check to ask a doctor "do you want to order iron studies on this patient?"
