Despite guidelines calling for universal testing of hepatitis C virus (HCV) among baby boomers, testing rates remain low, with various demographic factors influencing who is screened, as well as who is treated.

Researchers drew data from the Henry Ford Health System records to create a retrospective cohort of individuals born between 1945 and 1965 who were seen at 21 internal medicine clinics between July 2014 and June 2015. The study excluded those who had already been tested for hep C and those who were otherwise established as having the virus.

Compared with individuals falling outside the respective demographic groups, the following demographics were more likely to be screened for hep C by the following factors: African Americans (34 percent more likely), males (18 percent), those with electronic medical records (24 percent), those receiving care at a residency teaching clinic (20 percent) and those with a higher number of office visits (42 percent). Those with other medical conditions, known as comorbidities, were 13 percent less likely to be tested.

Those with Medicaid coverage were 79 percent less likely to be treated for hep C than those with other forms of medical coverage. There was also a trend toward a decrease in the likelihood of treatment among those with lower income. Those with electronic medical records were 2.73 times more likely to be treated than those without.
