Is there any good, consistent data that show emr's improve patient disease outcomes?

Registries, not EMRs: Emrs include any patient records that are computerized - some track disease management and others don't. Registries (usually electronic today, but can still be done on paper) help a doctor keep track of all of their patients with a specific health conditions (diabetes, for example) and see which patients are due for what care, whose test results are at goal, and who may need a reminder to come in.

Probably not: Va has long track and population that stays in the system. Better would be by prevention- like vaccination and flu shots and may count. Better may be by early detection in the screening programs, breast, aneyrysm etc. Better might be : timed, dated legible, scannable, findable, etc. Lot of time spent and distraction by the computer from the patient is a negative. .

None whatsoever: Current studies and data analysis show that EMRs do not improve disease outcomes. There seems to be no positive effect of these computer systems on health. They are good for data mining which might help in the future but the data mining currently is by regulators and insurance companies trying to save money.
