High priority for hepatitis C screening in safety net hospitals: Results from a prospective cohort of 4582 hospitalized baby boomers. Issue 5 (29th August 2015) - Turner, Barbara J.
Abstract Low‐income populations are disproportionately affected by hepatitis C virus (HCV) infection. Thus, implementing baby boomer screening (born 1945‐1965) for HCV may be a high priority for safety net hospitals. We report the prevalence and predictors of HCV infection and advanced fibrosis or cirrhosis based on the Fibrosis‐4 score plus imaging for a baby boomer cohort admitted to a safety net hospital over a 21‐month interval with >9 months of follow‐up. Anti‐HCV antibody testing was performed for 4582, or 90%, of all never‐screened patients, of whom 312 (6.7%) tested positive. Adjusted odds ratios of testing anti‐HCV‐positive were 2.66 for men versus women (P < 0.001), 1.25 for uninsured versus insured (P = 0.06), 0.70 for Hispanics versus non‐Hispanic whites (P = 0.005), and 0.93 per year of age (P < 0.001). Among 287 patients tested for HCV RNA (91% of all anti‐HCV‐positive cases), 175 (61%) were viremic (3.8% overall prevalence in cohort), which was 5% less likely per year of age (P < 0.03). Noninvasive staging of 148 (84.6%) chronic HCV patients identified advanced fibrosis or cirrhosis in 50 (33.8%), with higher adjusted odds ratios of 3.21 for Hispanics versus non‐Hispanic whites/Asians (P = 0.02) and 1.18 per year of age (P = 0.001). Other factors associated with significantly higher adjusted odds ratios of advanced fibrosis or cirrhosis were alcohol abuse/dependence, obesity, and being uninsured. Conclusion: In this low‐income, hospitalized cohort, 4% of 4582 screened baby boomers were diagnosed with chronic HCV, nearly twice the rate in the community; one‐third had noninvasive testing that indicated advanced fibrosis or cirrhosis, which was significantly more likely for Hispanics, those of older age, those with obesity, those with alcohol abuse/dependence, and those who lacked insurance.
