Hepatitis C Antibody Screening Among Baby Boomers by a Community-Based Health Insurance Company

Infection with the hepatitis C virus (HCV) is the most commonly reported bloodborne infection in the United States. Individuals born between 1945-1965, the baby boomers, account for approximately 75% of all chronic HCV infections in the United States. The purpose of this study was to determine if a 6-week intervention, including outreach, education, and incentive, by a community-based health insurance company could improve uptake of HCV antibody screening among the 1945-1965 birth cohort. Individuals were eligible to participate in this campaign if they were born on or after January 1, 1945 and on or before December 31, 1965, had health insurance with Sendero Health Plans during the intervention period, and had no evidence of having received an HCV antibody test prior to the campaign start date. The 6-week campaign period was from November 14, 2018 through December 31, 2018. A gift card incentive was provided if HCV screening was completed on or before December 31, 2018. A total of 5287 individuals were eligible to participate in the campaign. Members who were baby boomers were 3.36 times more likely to receive HCV antibody screening during the intervention period in 2018 than during a similar period in 2017 (prevalence ratio = 3.36; P < 0.0001; 95% confidence interval: 2.71, 4.16). Health officials have established the identification, treatment, and elimination of HCV as a national policy objective. Using an outreach, education, and incentive approach, Sendero Health Plans improved uptake of HCV antibody screening among the high-risk baby boomer population.
