Vaccination, screening, and linkage to care can reduce the burden of chronic hepatitis B virus (HBV) infection. However, recommendations vary among organizations, and their implementation has been suboptimal. The American College of Physicians' High Value Care Task Force and the Centers for Disease Control and Prevention developed this article to present best practice statements for hepatitis B vaccination, screening, and linkage to care.
A narrative literature review of clinical guidelines, systematic reviews, randomized trials, and intervention studies on hepatitis B vaccination, screening, and linkage to care published between January 2005 and June 2017 was conducted.
Clinicians should vaccinate against hepatitis B virus (HBV) in all unvaccinated adults (including pregnant women) at risk for infection due to sexual, percutaneous, or mucosal exposure; health care and public safety workers at risk for blood exposure; adults with chronic liver disease, end-stage renal disease (including hemodialysis patients), or HIV infection; travelers to HBV-endemic regions; and adults seeking protection from HBV infection.
Clinicians should screen (hepatitis B surface antigen, antibody to hepatitis B core antigen, and antibody to hepatitis B surface antigen) for HBV in high-risk persons, including persons born in countries with 2% or higher HBV prevalence, men who have sex with men, persons who inject drugs, HIV-positive persons, household and sexual contacts of HBV-infected persons, persons requiring immunosuppressive therapy, persons with end-stage renal disease (including hemodialysis patients), blood and tissue donors, persons infected with hepatitis C virus, persons with elevated alanine aminotransferase levels (≥19 IU/L for women and ≥30 IU/L for men), incarcerated persons, pregnant women, and infants born to HBV-infected mothers.
Clinicians should provide or refer all patients identified with HBV (HBsAg-positive) for posttest counseling and hepatitis B–directed care.
Summary of the American College of Physicians and Centers for Disease Control and Prevention best practice advice on hepatitis B vaccination, screening, and linkage to care for adults with chronic HBV infection.
anti-HBc = antibody to hepatitis B core antigen; anti-HBs = antibody to hepatitis B surface antigen; HBsAg = hepatitis B surface antigen; HBV = hepatitis B virus.

High prescription drug costs hinder adequate treatment of hepatitis B in the United States
We read with great interest the excellent Clinical Guideline published by Abara, et al in Annals of Internal Medicine in which the authors highlighted the sub-optimal rates of hepatitis B virus (HBV) screening and treatment in the United States.1 The authors note that many barriers prevent patients with HBV infection from receiving treatment but state that “linkage to care ensures that patients with chronic HBV infection receive treatment when they become eligible…” Although linkage to care is a crucial component of HBV treatment, our experience has been that linkage to care is not sufficient to ensure treatment. High prescription drug costs are a significant system-level barrier that must be considered when caring for patients with HBV infection in the United States.
The National Average Drug Acquisition Cost (NADAC) for a 30-day prescription of the three first-line drugs recommended for the treatment of chronic HBV is as follows: entecavir 0.5 mg tablet (Baraclude) ($115), tenofovir disoproxil fumarate (TDF) 300 mg tablet (Viread) ($1,028), and tenofovir alafenamide (TAF) 25 mg tablet (Vemlidy) ($965). In the case of TDF and TAF, prices likely reflect limited generic competition, a problem not unique to the HBV drug market.2
Since a typical treatment course generally exceeds 1 year (often lifelong), the cost of TAF or TDF can be cost-prohibitive. Although the price of TDF is likely to drop with additional generic entry,3 (as occurred with entecavir) the presence of at least 6 generic manufacturers is often required before the price drops to 25% of the original branded price.4 Until then, our experience has been that regardless of insurance status, HBV treatment is often unaffordable for patients without access to discount programs. Unfortunately, Patient Assistance Programs (PAPs) are not easily navigated, particularly for non-native English speakers, who make up a significant portion of those infected with hepatitis B in the United States. Thus, successful navigation of PAPs frequently requires dedicated support staff to help patients obtain patient assistance.5
In summary, while we agree that linkage to care is a crucial component of hepatitis B care, cost of treatment must be considered as a key systems barrier for patients with HBV in the United States. Navigating this barrier successfully requires a well-funded clinic and dedicated staff willing and able to work closely with patients to ensure that treatment is not unnecessarily delayed, and can be continued without lapses in therapy.
