Continuum of Care for Hepatitis C Virus Among Patients Diagnosed in the Emergency Department Setting.

BACKGROUND.: Urban emergency departments (EDs) seem to be able to detect new hepatitis C virus (HCV) infections at a high rate, but it is unknown the extent to which individuals screened in the ED can progress to treatment and cure. We evaluate the HCV Continuum of Care for patients identified with HCV in 2 urban EDs, and consider the results in the context of outcomes from ambulatory screening venues where 2%-10% of chronically infected patients are treated. METHODS.: This is a multicenter, retrospective cohort study of 2 ED HCV screening programs. Patients who screened HCV antibody reactive between 1 May and 31 October 2014 were followed for up to 18 months. The main outcome was the absolute number and proportion of eligible patients who completed each stage of the HCV Continuum of Care. RESULTS.: A total of 3704 ED patients were estimated to have undiagnosed HCV infection, and screening identified 532 (14.4%) HCV antibody-reactive patients. Of the 532 HCV antibody-reactive patients, 435 completed viral load testing (82%), of whom 301 (69%) were chronically infected. Of the 301 chronically infected patients, 158 had follow-up arranged (52%), of whom 97 attended their appointment (61%). Of these 97, 24 began treatment (25%), and 19 of these 24 achieved sustained virological response (79%). CONCLUSIONS.: Urban EDs serve patients with poor access to preventive care services who have a high prevalence of HCV infection. Because ED patients identified with HCV infection can progress to treatment and cure with rates comparable to ambulatory care settings, implementation of ED HCV screening should be expanded.

Characterizing Failure to Establish Hepatitis C Care of Baby Boomers Diagnosed in the Emergency Department.

BACKGROUND: Emergency departments (EDs) are high-yield sites for hepatitis C virus (HCV) screening, but data regarding linkage to care (LTC) determinants are limited. METHODS: Between September 2013 and June 2014, 4371 baby boomers unaware of their HCV status presented to the University of Alabama at Birmingham ED and underwent opt-out screening. A linkage coordinator facilitated referrals for positive cases. Demographic data, International Classification of Diseases, Ninth Revision codes, and clinic visits were collected, and patients were (retrospectively) followed up until February 2015. Linkage to care was defined as an HCV clinic visit within the hospital system. RESULTS: Overall, 332 baby boomers had reactive HCV antibody and detectable plasma ribonucleic acid. The mean age was 57.3 years (standard deviation = 4.8); 70% were male and 61% were African Americans. Substance abuse (37%) and psychiatric diagnoses (30%) were prevalent; 9% were identified with cirrhosis. During a median follow-up of 433 days (interquartile range, 354-500), 117 (35%) linked to care and 48% needed inpatient care. In multivariable analysis, the odds of LTC failure were significantly higher for white males (adjusted odds ratio [aOR], 2.57; 95% confidence interval [CI], 1.03-6.38) and uninsured individuals (aOR, 5.16; 95% CI, 1.43-18.63) and lower for patients with cirrhosis (aOR, 0.36; 95% CI, 0.14-0.92) and access to primary care (aOR, 0.20; 95% CI, 0.10-0.41). CONCLUSIONS: In this cohort of baby boomers with newly diagnosed HCV in the ED, only 1 in 3 were linked to HCV care. Although awareness of HCV diagnosis remains important, intensive strategies to improve LTC and access to curative therapy for diagnosed individuals are needed.
