293. Hepatitis C is now a Millennial Disease in Response to the Opioid Crisis: A Demographic Shift in Hepatitis C Infection

Abstract

BackgroundPrevious research has shown millennials represent the fastest growing generation for those infected with the hepatitis C virus (HCV). Millennials are also a key driver in the opioid crisis, particularly in states of the Appalachian region including Kentucky. Despite research demonstrating a change in prevalence from baby boomers (born 1945–1965) to millennials (born 1980–1995), large representative studies providing evidence of the magnitude of this demographic shift are lacking in the United States. Our objective was to assess trends of HCV infection since 2016 in a large healthcare system located in an area of high prevalence of opioid use and HCV infection.MethodsAll individuals were screened for HCV infection in 2016, 2017, and 2018 within Norton Healthcare per standard risk-based criteria (e.g., injection drug users, baby boomers, etc.) as recommended by CDC, except for pregnant women who were universally screened since 2016. We tested for demographic shifts over time using longitudinal and time series analyses techniquesResultsA total of 86,243 individuals were screened for HCV infection from 2016 to 2018. Of those, 2,615 (3.0%) individuals screened positive for chronic HCV. The average age of those infected significantly decreased by an average of 3.7 years annually (from 47.3 years in 2016 to 39.9 years in 2018, P < 0.001). We forecast a plateau near the age of 28 years will be observed in just over 7 years. In addition, the proportion of millennials increased over time (33.6% in 2016, 42.4% in 2017 and 51.4% in 2018, P < 0.001), while baby boomers significantly decreased over time (44.0% in 2016, 38.8% in 2017, and 29.3% in 2018, P < 0.001). Lastly, over time, those with chronic HCV were more likely to be male (increasing from 49.6% to 54.4%, P = 0.008) and Hispanic (increasing from 1.6% to 17.7%, P < 0.001)ConclusionOur results suggest that HCV infection has become a predominately millennial disease, skipping a generation. These results correlate with trends seen with the opioid epidemic, which is driven by millennials. We conclude that the opioid crisis has led to a drastic demographic shift, and currently the typical HCV-infected individual is a younger male. Without interventions, this trend will continue for over seven years, plateauing near the demarcation of millennials and generation ZDisclosures All authors: No reported disclosures.
