Medicare Lacks Health IT
The study linked Medicare claims data to the nationally representative physician survey conducted by HSC.
Researchers found that 57 percent of Medicare outpatient visits were to physicians in practices that used IT for no more than one of the following five clinical functions: obtaining treatment guidelines, exchanging clinical data with other physicians, accessing patient notes, generating preventive treatment reminders for the physicians use and writing prescriptions.
