Expanded Hepatitis C Virus Screening Recommendations Promote Opportunities for Care and Cure 
Chronic hepatitis C virus (HCV) infection is a major health problem in the United States. An estimated 2.7 million to 3.9 million Americans are living with HCV, and transmission continues to occur (1). Hepatitis C is the leading cause of liver transplants in the United States, and without treatment, 15% to 40% of persons living with the virus will develop cirrhosis or cancer. Hepatitis C–related mortality has been steadily increasing, with a 50% rate increase from 1999 to 2007. An estimated 45% to 85% of persons with chronic HCV are unaware that they are infected and thus do not receive needed care and treatment (1). The Centers for Disease Control and Prevention (CDC) estimates that, in the absence of interventions, approximately 1 million HCV-infected persons will die of HCV-related disease. When accompanied by appropriate care and treatment, HCV testing can reduce risk by 70% for hepatocellular carcinoma and by 50% for all-cause mortality (1).

The U.S. Preventive Services Task Force (USPSTF) recommendations on HCV screening (4) represent a critical step toward achieving the prevention goals outlined in the HHS action plan. The USPSTF now recommends HCV screening in persons at increased risk and 1-time screening in adults born between 1945 and 1965. These recommendations, which are consistent with those issued by the CDC in 2012 (5), reflect the strength of evidence on the benefits of HCV testing linked to care, treatments, and improved health outcomes. The independently derived yet similar recommendations for HCV testing from the USPSTF and CDC send a clear signal to health care professionals, policymakers, and the public that screening for HCV is effective. We can now focus our efforts on ensuring capacity for the delivery of clinical preventive services that can reduce missed opportunities for HCV diagnosis and linkage to care and treatment. 
Risk-based approaches (6) have been most effective in settings providing services for persons with ongoing risk behaviors or health issues indicative of those risks (for example, HIV-infected persons and those receiving dialysis or substance abuse treatment); however, these approaches have been less effective in identifying HCV infection in the general population, particularly in persons infected in the distant past. Among persons living with hepatitis C, approximately 76% were born between 1945 and 1965; persons in this birth cohort (“baby boomers”) accounted for more than 70% of all HCV-associated deaths in 2007 (5). This cohort may have received blood transfusions before the introduction of screening in 1992 or have a history of other risk factors. However, many in this cohort do not or cannot identify any risk factors for their infection. As such, a risk-based approach may miss a substantial proportion of HCV-infected individuals who may remain asymptomatic and unaware of their infection for years.
The expanded screening recommendations are especially important in light of highly effective treatment for HCV. Currently available antiviral agents can elicit a sustained virologic response (virologic clearance or cure) in up to 79% of patients when administered with pegylated interferon and ribavirin, and the benefits of HCV treatment are expected to increase. On the basis of clinical trial data for 2 agents submitted in new drug applications to the U.S. Food and Drug Administration, future treatment regimens will comprise 1 or more antiviral agents (given either with pegylated interferon and ribavirin or as all-oral combinations) and are expected to yield similar or improved rates of viral clearance. These new regimens require shorter durations of treatment (12 to 24 weeks rather than current 24- to 48-week regimens) and are associated with fewer serious adverse events (7).
The promise of improved health outcomes will be realized with successful implementation of both risk-based and birth cohort–based strategies for HCV testing and linkage to care and treatment. Given the USPSTF's grade B designation for HCV testing in baby boomers and others at risk for infection, the 2010 Patient Protection and Affordable Care Act (Affordable Care Act) will facilitate implementation because it requires nongrandfathered, private health plans to cover clinical preventive services given an A or B grade by the USPSTF without cost sharing and provides incentives for Medicaid programs to cover these services. The law will also prohibit insurance companies from declining to sell or renew policies because of such preexisting conditions as viral hepatitis, thus increasing patient access to care and treatment called for in the HHS action plan. The American Recovery and Reinvestment Act and the Affordable Care Act will improve health infrastructure by fostering the development of new health information technology and health information exchanges. Implementation of standards for electronic medical records can expedite the reporting of HCV-related laboratory and clinical information to public health surveillance systems and close current gaps in screening. As demonstrated by surveillance data, 50% of newly reported HCV cases lack a positive RNA test result (8); electronic medical records can facilitate implementation of recommended HCV testing policies. They also provide an opportunity to monitor the quality of prevention, care, and treatment of viral hepatitis at the public health level.

The comprehensive screening strategies recommended by the USPSTF and CDC create new opportunities for reaching the shared goals of reducing HCV transmission and identifying persons living with HCV and facilitate the receipt of care and treatment. Passage of the Affordable Care Act has created an environment conducive to implementation of risk-based and birth cohort–based strategies. Taken together, the law and newly expanded HCV screening recommendations will help generate the momentum needed to identify millions of Americans previously unaware of their infection status, thus preventing liver disease and deaths attributable to chronic HCV infection.

CDC is augmenting previous recommendations for HCV testing (CDC. Recommendations for prevention and control of hepatitis C virus (HCV) infection and HCV-related chronic disease. MMWR 1998;47[No. RR-19]) to recommend one-time testing without prior ascertainment of HCV risk for persons born during 1945-1965, a population with a disproportionately high prevalence of HCV infection and related disease. Persons identified as having HCV infection should receive a brief screening for alcohol use and intervention as clinically indicated, followed by referral to appropriate care for HCV infection and related conditions. These recommendations do not replace previous guidelines for HCV testing that are based on known risk factors and clinical indications. Rather, they define an additional target population for testing: persons born during 1945-1965. CDC developed these recommendations with the assistance of a work group representing diverse expertise and perspectives. The recommendations are informed by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework, an approach that provides guidance and tools to define the research questions, conduct the systematic review, assess the overall quality of the evidence, and determine strength of the recommendations. This report is intended to serve as a resource for health-care professionals, public health officials, and organizations involved in the development, implementation, and evaluation of prevention and clinical services. These recommendations will be reviewed every 5 years and updated to include advances in the published evidence.
