Hepatitis C Virus Testing and Linkage to Care in North Carolina and South Carolina Jails, 2012-2014

OBJECTIVE

We evaluated a hepatitis C virus (HCV) testing and linkage-to-care post-release program among detainees of small- to medium-sized jails in North Carolina and South Carolina as part of the Hepatitis Testing and Linkage to Care initiative.

METHODS

An HCV testing and linkage-to-care program was implemented in selected jails in North Carolina and South Carolina from December 2012 to March 2014. Health-care workers not affiliated with the jails conducted HCV antibody (anti-HCV) and HCV ribonucleic acid (RNA) testing and linkage-to-care activities. The North Carolina jail provided universal opt-out testing for HCV; South Carolina jails initially targeted high-risk individuals before expanding to routine testing.

RESULTS

Of 669 detainees tested for HCV in North Carolina, 88 (13.2%) tested anti-HCV positive, of whom 81 (92.0%) received an HCV RNA test, 66 (81.5%) of whom tested HCV RNA positive (i.e., currently infected). Of the 66 detainees with current HCV infection, 18 were referred to HCV medical care post-release and 10 attended their first appointment. Of 224 detainees tested for HCV in South Carolina, 18 (8.0%) tested anti-HCV positive, of whom 13 received an HCV RNA test. Nine of 13 detainees tested HCV RNA positive, seven detainees were referred to post-release medical care, and two detainees attended their first appointment. Overall, 106 of 893 (11.9%) detainees were anti-HCV positive.

CONCLUSION

This study demonstrated that HCV testing, identification of infection, and linkage to care are feasible among jail populations. The rate of anti-HCV positivity was lower than that found in national studies of incarcerated populations, suggesting that HCV infection prevalence in jails may vary across U.S. states or regions.

Testing and Linking Foreign-Born People with Chronic Hepatitis B Virus Infection to Care at Nine U.S. Programs, 2012-2014

OBJECTIVE

Hepatitis B virus (HBV) infection continues to be a public health threat in the United States. As many as 2.2 million people are infected, approximately 70% of whom are foreign-born, and fewer than one-third are aware of their infection. We launched an HBV testing and linkage-to-care initiative among foreign-born people.

METHODS

As part of the Hepatitis Testing and Linkage to Care (HepTLC) initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites, nine U.S. programs in seven states conducted HBV screening from October 2012 to September 2014. The nine programs partnered with health-care centers and community-based organizations to recruit foreign-born people recommended for HBV testing. We assessed patient characteristics, region of origin, risk factors, hepatitis B surface antigen (HBsAg) status, and referral to medical care.

RESULTS

Of 23,144 participants tested for HBV, 1,317 (5.7%) were HBsAg positive. Of these, the median age was 47 years, 1,205 (91%) had at least one risk factor for HBV infection, 1,117 (85%) received posttest counseling, 1,098 (83%) were referred to care, and 606 (46%) attended a first medical appointment. The proportion of HBsAg-positive participants by region of origin included Africa (10%, 206/2,129), Western Pacific (6%, 616/9,673), Eastern Mediterranean (5%, 174/3,337), Southeast Asia (5%, 191/3,891), South America (2%, 6/252), Eastern Europe (2%, 6/262), and North America (1%, 17/1,936).

CONCLUSION

Community-based HBV testing initiatives can identify substantial numbers of people with chronic HBV infection, inform them of their infection status, and provide posttest counseling and linkage to care. However, strategies are needed to improve linkage to HBV-directed medical care for foreign-born individuals living with chronic HBV infection.

Early Identification and Linkage to Care for People with Chronic HBV and HCV Infection: The HepTLC Initiative

OBJECTIVE

In 2012, CDC's Division of Viral Hepatitis launched a public health initiative to increase hepatitis B virus (HBV) and hepatitis C virus (HCV) infection testing for those at risk and to improve linkage to medical care for those infected. We describe testing outcomes of previously unidentified people at risk for HBV and HCV infection and the lessons learned while linking patients to care.

METHODS

CDC's Hepatitis Testing and Linkage to Care (HepTLC) initiative provided 34 financial awards to U.S. organizations that serve people at risk for viral hepatitis, 25 of which focused on HCV and nine of which focused on HBV. Grantees offered testing and test result notification to people at risk for HBV and/or HCV infection, as well as counseling, referral, and verification or notification of linkage to care for people with positive test results. We entered demographic data, self-reported risk factors, country of origin (for HBV), and testing outcomes into a confidential database.

RESULTS

The 34 grantees tested 87,860 people at more than 260 sites in 17 states. Of the 23,144 people tested for HBV, 1,317 (6%) were positive. Of the 64,716 people tested for HCV, 57,570 (89%) received an HCV antibody (anti-HCV) test, of whom 7,580 (13%) tested anti-HCV positive. Of the 4,765 people who received an HCV RNA test, 3,449 (72%) tested positive. Of the 4,766 people who tested positive for either HBV or HCV infection, 2,116 (44%) were linked to care.

CONCLUSION

Interventions targeting people at risk for HBV and HCV infection reached a substantial number of people for whom testing is recommended and identified a large proportion of those who had previously unrecognized infection. Patient navigation was critical for follow-up and linkage to care.

Early identification and linkage to care of persons with chronic hepatitis B virus infection--three U.S. sites, 2012-2014

In the United States, an estimated 0.8-1.4 million persons are living with chronic hepatitis B virus (HBV) infection. Among these persons, as many as 70% were born in countries of Asia, Africa, or other regions where HBV is moderately or highly endemic (hepatitis B surface antigen [HBsAg] prevalence ≥2%). HBV-associated cirrhosis and liver cancer are major health problems for these populations. Most persons with HBV were infected at birth or during early childhood and are asymptomatic until advanced liver disease develops. To address these concerns, CDC recommends HBsAg testing for all persons born in these areas and linkage to medical care and preventive services for those who are infected. In 2012, CDC awarded funds to nine sites to implement this recommendation. This report describes programs at three sites (New York, New York; Minneapolis-St. Paul, Minnesota; and San Diego, California) that conducted HBV testing, in clinical or community settings, and referred for medical evaluation and care those persons whose HBsAg test results were positive. During October 2012-March 2014, the three sites tested 4,727 persons for HBV infection; 310 (6.6%) were HBsAg-positive. Among the HBsAg-positive persons, 94% were informed of their results, 90% were counseled, 86% were referred for care, and 66% attended their scheduled first medical visit. These projects demonstrate that community-based programs can identify infected persons among populations with a high prevalence of HBV infection and refer HBsAg-positive persons for care. Individualized efforts to assist patients with accessing and receiving health-care services ("patient navigation services") can increase the number of persons who follow up on referrals and receive recommended care.
