Fewer than 1 in 3 people infected with hepatitis C virus (HCV) begin receiving treatment within a year of their diagnosis, according to a new report by the Centers for Disease Control and Prevention (CDC).
Although HCV infection can be cured in more than 95% of patients with safe, oral medication, many barriers prevent people from receiving the care they need, experts say. These include insurance restrictions and the need for specialist visits.
"If we are going to make an impact against hepatitis C, we need to connect more people to treatments and reduce disparities of access to diagnosis and treatment," said Carolyn Wester, MD, MPH, director of the CDC's Division of Viral Hepatitis, during an August 9 press call. "People shouldn't have to jump over hurdles to access lifesaving treatments."
The CDC report was published in Vital Signs on August 9.
An estimated 2.2 million Americans are living with HCV infection. The most recent data indicate that new infections increased more than threefold from 2011 to 2019. HCV transmission usually occurs through contact with the blood of an infected person. Today, most people become infected with the virus by sharing needles, syringes, and other equipment used to inject drugs, according to the CDC.
The researchers used a nationwide administrative claims database to identify more than 47,600 adults diagnosed with HCV infection from January 30, 2019, through October 31, 2020. Most patients (79%) were Medicaid recipients, 7% were Medicare patients, and 14% had private insurance. CDC researchers found that just 23% of Medicaid recipients, 28% of Medicare patients, and 35% of patients with private insurance began receiving direct-acting antiviral agents (DAAs) within 360 days of receiving a positive HCV test result. Of those who did receive treatment, most (from 75% to 84%) began receiving treatment within 180 days of their diagnosis.
Among people on Medicaid plans, patients who lived in states with treatment restrictions were 23% less likely to receive timely treatment (adjusted odds ratio, 0.77; 95% CI, 0.74 – 0.81) compared to those living in states with no restrictions. Medicaid patients who were Black or of another race other than White were also less likely than White patients to be treated for HCV within the same year as their diagnosis. The lowest rates of treatment were among adults younger than 40 years, regardless of insurance type. This age group had the highest rates of new infections.
Actual treatment percentages may be even smaller than the number captured in this study, because the study included patients with continuous insurance coverage, Wester said, "so in many ways, [these] are the individuals who are set up to have the best access to care and treatment."
Wester mentioned several steps that could improve access to DAAs for patients with HCV infection:
Provide treatment outside of specialist offices, such as primary care and community clinics, substance use treatment centers, and syringe services programs.
Increase the number of primary care providers offering hepatitis C treatment.
Provide treatment in as few visits as possible.
Eliminate restrictions by insurance providers on treatment.
A "Health Injustice"
While DAA treatments are effective, they are also expensive. Generic medications cost around $24,000 for a 12-week course, and some brand-name drugs are estimated to cost more than three times that amount. Many insurance companies, therefore, have treatment restrictions in place, including the following:
There must be evidence of liver fibrosis for a patient to be treated.
The doctor prescribing treatment must be a liver specialist or an infectious disease specialist.
The patient must meet sobriety requirements.
Treatment requires preauthorization approval from insurance carriers.
These criteria prevent patients from getting the care that they need, said Jonathan Mermin, MD, MPH, director of the CDC's National Center for HIV, Viral Hepatitis, STD, and TB Prevention, during the press call. "Restricting access to hepatitis C treatment turns an infectious disease into a health injustice," he added.
Oluwaseun Falade-Nwulia, MBBS, MPH, an infectious disease specialist and assistant professor of medicine at the Johns Hopkins University School of Medicine, Baltimore, emphasized the importance of removing barriers to HCV treatment and expanding HCV care out of specialist offices. She noted that treatment for HCV infection should begin immediately after a patient's diagnosis. Previously, guidelines recommended waiting 6 months from the time a patient was diagnosed with HCV to begin treatment to see whether the patient's body could clear the infection on its own. Now, guidelines recommend that after a diagnosis of acute HCV, "HCV treatment should be initiated without awaiting spontaneous resolution." But some insurance companies still ask for evidence that a patient has been infected for at least 6 months before approving therapy, Falade-Nwulia noted.
"We have a system that has so many structural barriers for patients who we know already have so many social determinants of health working against them to access any healthcare," she said. "I think it's doubly devastating that patients that can actually get to a provider and get a prescription may still not have access to [the medication] because of structural barriers, such as restrictions based on a need to prove chronicity."
