V. Q and A
I. Hepatitis C:
Background /Rationale
What it is?
• Contagious infectious disease caused
by an RNA virus
How is it acquired/transmitted?
•
•
•
•
Most commonly by direct contact with blood from an infected person
Pre ~1990s: Primarily via blood transfusions or organ transplantation
Currently: Primarily via sharing needles/equipment (intravenous drug users)
Other routes (less common): Sexual contacts, Maternal-fetal, Sharing
personal items (e.g. razor blades), Tattooing

Hepatitis C (what happens?)
Acute Hepatitis C Virus infection:
• Short-term illness < 6 months of exposure
• Acute leads to chronic infection for most
people
Time….
Chronic Hepatitis C virus infection:
• Long-term illness which can last a lifetime
• Potential for serious liver problems,
including cirrhosis (scarring of the liver)
liver cancer and death

http://www.hepatitisc.uw.edu/go/evaluation-staging-monitoring/natural-history/core-concept/all
20 – 30 years
HCV – Disease burden
Worldwide
• 130–150 million chronic HCV
• ~350,000 HCV related deaths/year
United States
• 3.5 million with chronic HCV
• ~15,000+ HCV related deaths/year
• Significant reduction (screening blood supply)
• Emerging epidemic (IDUs)
• Epidemiology not fully characterized
• ~50% remain unaware of their infection

HCV: Disease Burden in US
The number of deaths due
to hepatitis C is at an alltime high in the US and
exceeds those attributable
to 60 other infectious
diseases including HIV and
tuberculosis
Ly KN, et al. Rising Mortality Associated With Hepatitis C Virus in the United States, 2003-2013. Clinical Infectious Diseases.
2016;62(10):1287-1288.
What’s possible regarding control and treatment?
• The good news
• Antiviral medicines can CURE approximately 90% of persons with hepatitis C
reducing risk of death from liver cancer and cirrhosis
• The challenge
• Typically indolent (clinically silent)
• Optimal systems for screening, linkage to care and treatment remain under
development
• Resource constraints
Who should be screened for Hepatitis C Virus?
2012 CDC Screening Recommendations AUGMENTED
prior targeted screening recommendations
• IVDU
• Recipients of clotting factors*, solid organ
transplant
• Hemodialysis patients
• HIV
• Persons with signs/symptoms of liver disease**
• Children born to HCV positive mothers
*before 1987; before 1992’; **e.g. elevated AST
Addition of ‘birth cohort’:
• Adults born between 1945-1965
(75% of those infected with HCV fall in this cohort)
Why EMERGENCY DEPARTMENTS?
• Front Door Health System
• Open 24/7
• Critical component of the
public health infra-structure
• > 140 million visits/year
• ~50% US population use ED
at least one visit /year
• EDs have track record
experience /success public
health interventions*
• Challenged by increasing
demands

Rationale for ED HIV/HCV Screening
Populations Known to Be Disparate
Users of U.S. ED Services:
Uninsured, Medicaid Recipients,
Non-Whites,
Persons Living Below U.S. Poverty Level
Known to Be Disproportionately Affected
with HIV / HCV Infection

Often Lack Access to Primary CareBased Preventative Screening

Similarities Between HIV and HCV
• Silent, indolent
• Under-recognized by providers
• Stigmatized: Association with stigmatizing behavior
• High morbidity and mortality if left unrecognized
• Screening, diagnosis, LTC has a significant impact
ED Screening for HIV: Lessons learned
and evolving paradigm with HCV
HIV*
• Large numbers of patients can be effectively screened
• Processes established for streamlining screening, LTC and treatment
• Systems for reimbursement and sustainability have been achieved
HCV*
• Ongoing research required to better understand epidemiology
• Diagnostic algorithms are distinct/ evolving and can be complex
• Pilot programs and implementation science required
• Policy changes and longitudinal sustained partnerships required
*Tie-in with clinical mission

Background
•
One-time baby boomer birth cohort screening is added in the 2012
CDC revised HCV screening recommendations. In 2013, USPSTF
recommends HCV screening for adults at high risk (including birth
cohort screening) at Grade B.
•
EDs are considered a key venue for HCV testing because of their
history of success in HIV screening given the populations they serve.
•
High Seroprevalence of HCV infections (chronic or ever) in ED
patients.
•
Risk-based targeted plus birth cohort screening would miss 50%.
(Merchant, 2013)
Objectives
• To determine the overall burden of undocumented HCV
infection in an urban ED
• To evaluate CDC recommendations for one-time HCV
testing in “baby boomers” in an urban ED
Methods
Setting:
• An urban adult ED with 66,000 annual census; high HCV
seroprevalence
Study Period:
• 8 weeks (24h/d), 06/2013–08/2013
Design:
• Cross-sectional identity-unlinked seroprevalence study methodology
• Sociodemo/HCV information from the administrative and EMR
database
• Waste blood samples were tested for HIV and HCV infection (HCV
EIA)
• “Undocumented HCV infection” was operationally defined as
presence of anti-HCV Ab in the absence of evidence of HCV
infection in EMR.

Conclusions
• High seroprevalence of HCV infection in our ED, indicating
that urban EDs could be a valuable venue for HCV testing.
• Birth cohort testing would augment identification of
undocumented HCV infections two fold.
• However, 25% would still remain undiagnosed, suggesting
the need to consider modification of the CDC
recommendations in ED settings.

Pragmatic Targeted Screening Missed the Mark
Identifying non-baby boomer targets
(IDUs) is challenging
• 85% of persons tested were baby boomers
or older at UAB
• UAB tests for IDU risk accounted for <5% of
all test orders
• Incidental (non-risk based) tests of persons
born after 1965 revealed 10% HCV-Ab
prevalence at UAB
Stigma barriers
• Provider - not asking IDU questions
• Patient – recall bias, privacy
Universal HCV Testing Eligibility
• Born after 1944*
• Age >13 - 18 years*
• Medically stable for HCV
questionnaire
• Self-reports no prior HCV diagnosis
• No prior test result in the EHR
