HIV/HBV/HCV Triple Screening in Primary Care

Summary

Design:

This will be a within-subjects repeated-measures design, testing an electronic medical record pop-up alert linked to order panels for screening blood tests for human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Study participants will be primary care providers. For each participating provider, their encounter will be randomized to either control (no alert; no changes to EMR interface) or an alert with triple-testing order panel intervention arm (alert linked to order panel with screening tests for all three bloodborne viruses (BBVs) selected by default; the alert will be triggered when a provider attempts to order a screening test for at least one BBV). The alert linked to triple testing orders will only be triggered if the provider orders a virus BBV screening test based on their normal practice and standard of care for their patient. Providers will see which orders are selected prior to signing (finalizing) them; therefore, this study will be unblinded. To mitigate the effect of unblinding, randomization will occur at the encounter level which will lead to providers experiencing both the control and intervention conditions randomly throughout the duration of the study.

Outcomes/endpoints:

The investigators will compare incidences of HIV, HBV, and HCV diagnoses between the two encounter conditions, estimate number of cases missed by not triple-testing, estimate laboratory costs per condition, and measure patient encounters per condition.

electronic medical record alert linked to orders

An electronic medical record alert linked to triple testing orders will be built specifically for this study. An order for a screening blood test for any of the three bloodborne viruses (BBVs; i.e. HIV, hepatitis B virus (HBV), or hepatitis C virus (HCV)) will trigger an electronic medical record alert linked to orders for screening blood tests for all three BBVs to be selected by default. If participants accept the alert, the individual BBV order that triggered the alert will be replaced with the pre-selected screening orders for all three BBVs. If the participants dismiss the alert, the individual BBV screening test order that triggered the alert will be accepted without the addition of screening test orders for the other two BBVs. This alert with linked orders will only be available to participating providers throughout the duration of the study, and will only activate for encounters randomized to "intervention" encounters.
