Advanced Electronic Population Health and Personal Health Record Tools to Improve Once Lifetime Hepatitis C Screening

All patients had to have an active personal health record account at the time of being randomized. Patients had to have been seen by their primary care provider in the last 6 months to be eligible and therefore had a "missed opportunity" for Hepatitis C screening. Control group received "usual care" which in our system included alert (health maintenance reminder) to the primary care provider at the time of the visit and passive alert in their personal health record (i.e. an alert if they log into their personal health record and look for reminders for preventative care that it due/overdue). Intervention group received same care as control group plus automatic ordering of the hepatitis C screening test and active electronic letter their personal health record that they were due for hepatitis C screening, what hepatitis C is, what the testing and if positive, treatment could involve, and instruction to go to one of the laboratories in the healthcare system to have their blood drawn if they were interested in the testing.
