Once developed, the intervention will then be used in combination with a physician panel notification and tested against physician panel notification only in a randomized controlled trial to see which approach is better in increasing the rate of hepatitis B and C screening. The team will also work with the 2 healthcare system to ensure that the interventions will be practical and easily adopted once the study is over. The findings of this project will greatly expand understanding about how to use technology- based interventions to improve quality of healthcare in diverse patient populations.
