Was this conclusively measured? I imagine there are fewer errors or better decisions made due to quick and easy availability of health history.
I trust auditable, easily legible notes over chicken scratch handwriting faxed from office to office in previous years. With EHR, I can also catch healthcare providers writing notes about stuff that did not happen in the visit to cover their ass, although I imagine many doctors do this because a lot of the minutiae is a waste of time that just serves to help in case of lawsuits or billing disputes. But in any case, I would rather have access to that info than not in case in need to dispute it.
