Hepatitis C virus screening trends: A 2016 update of the National Health Interview Survey

50% of liver cancer is caused by hepatitis C virus (HCV). Baby boomers are at increased risk and are recommended for one-time HCV screening. However, <13% of baby boomers were screened in 2015.

We are updating a previous study using 2013-2015 NHIS data to examine HCV screening prevalence by birth cohort, with 2016 data. We used logistic regression to evaluate whether HCV screening prevalence changed over time, stratified by birth cohort.

The sample consisted of 132,742 participants from 2013-2016. Screening increased in baby boomers from 11.9 to 14.1%. Odds of HCV screening for baby boomers was significantly associated with age, gender, race/ethnicity, and other variables and increased significantly with each subsequent year (aOR = 1.21, aOR = 1.33, aOR = 1.42, consecutively). While HCV screening is increasing over time, there is still room for improvement and future interventions should focus on increasing HCV screening among groups demonstrating significantly lower screening prevalence.
