Hepatitis C Care: Check Your Biases at the Door

Medscape Infectious Diseases

International Conference on Viral Hepatitis (ICVH) 2014

Helen-Maria Lekas, PhD, Gloria J. Searson, MSW, Alyson L. Harty, RN, BSN, William Thompson

June 23, 2014

Editor's Note: During the International Conference on Viral Hepatitis, held in New York, some of the participants in a panel discussion titled "Patient Perspectives on What Providers Need to Know About Stigma and Other Barriers to Hepatitis Care"[1] convened afterwards for a discussion. During the conversation, they discussed the stigma surrounding hepatitis C and some of the barriers to diagnosis and treatment for patients.

Living With Hepatitis C

Helen-Maria Lekas, PhD: My name is Helen-Maria Lekas. I am from Columbia University, and I am in New York at the International Conference on Viral Hepatitis. I'm here with a panel of experts, including Gloria Searson, Alyson Harty, and William Thompson. I would like to start by asking you about stigma. As patients and experts living with hepatitis C virus (HCV) infection, what do you want your providers to know about the stigma associated with the disease?

Gloria J. Searson, MSW: Stigma is horrible. I don't want to be looked at or judged, and I don't want you to bring your biases into the room with us. I just want you to treat me as a human being and take care of the problem.

Alyson Harty, RN, BSN: I agree, from both the provider and patient perspective. When I was 17 and I found out I had HCV, I didn't want to tell any of my friends. You don't want your friends knowing that you have a virus because it's often associated with other viruses that have a broad stigma against them, and there is no need. You got it -- however you got it, you got it -- let's solve the problem.

Dr. Lekas: What can providers do to ameliorate the stigma associated with HCV?

William Thompson: One thing that I find very important is the support group that I go to. We get a lot of information from the doctor and we also get a lot of information from other patients. To me, stigma is like "sticks and stones can break my bones." It doesn't really affect me. I don't think anybody can say anything to me that would make me feel bad about my condition, especially when you have conditions yourself. It's all up to the individual in how you feel about it.

Persisting Barriers to Diagnosis and Treatment

Dr. Lekas: I'm very glad to hear that you don't internalize other people's stigmatizing attitudes. If we leave stigma aside, what are some of the other barriers that patients are encountering in getting care for HCV?

Ms. Searson: Patients don't have the same care teams available to them for HCV that they did for other diseases. One of the good things about HIV was that they had funding and manpower to help deal with teaching the patient things that the doctor may not have been able to get through to the patient, or convince the patient of the urgency of something. They even had someone there to provide the education and support so that they can buy into the fact that they had the disease. There are some systemic barriers that we have to fix in healthcare in general. It is disproportionately dispensed in different areas, in different ways, and we have to make sure that people can access the same things wherever they are geographically. That's one of the largest barriers. The treatments are good, but we can't just take them without understanding them. So, who is going to provide that education is the key.

Dr. Lekas: Do you think that patients with HCV know about the new treatments coming down the pipeline?

Ms. Harty: It varies. You have your highly educated patients who know that they have HCV and who have been following the disease and the press releases, and then you have patients who were told back in the late 1990s and early 2000s that they have this problem but nothing can be done about it. There is a wide variety, and we need re-education for those patients who were turned away from care. For example, they may have been told that because they were black or obese that the treatment wouldn't work for them. We need to relink these patients back to care, as well as screen the 80% of patients who we know haven't been tested.

Ms. Searson: The campaigning and awareness are out there for those who access social media or the Internet or who watch television, but there is a whole group of people who do not access information the way it is being disseminated. If you are not in the healthcare system or working with a substance abuse group, a senior population, or a veterans' group, you still may be out of the loop for hepatitis. We need the healthcare team around patients who get HCV to understand them as a whole -- where they are and what may or may not be necessary for this particular patient to get through treatment. The pills and the medications only address one barrier, and that's the biological barrier. They don't address the personal issues or the systemic barriers, and they certainly don't address the infrastructure and lack of healthcare providers able to deal with this disease.

Improving on the HIV Model for Hepatitis C

Dr. Lekas: Would you propose a team-based approach for hepatitis C, like that for HIV, with a provider, a medical physician, and a nurse?

Ms. Harty: We need a lot more funding for that. Personally, working in a private office, I know that we don't have the funds to hire a psychiatrist. I am the social worker, psychiatrist, and nurse -- all of the above. It takes a lot of manpower to put people through this therapy, and the providers also need more support from the states and the private insurers who don't pay for psychological therapy unless the patient has Medicaid and can access a therapist. It is very hard for privately insured people to get the psychological therapy that they need.

Dr. Lekas: Do you think the HIV model is a good one?

Ms. Harty: Definitely.

Ms. Searson: Yes, especially because this is a complicated thing to explain, and you want to have people you can trust, like we have with case managers in HIV. But here is one thing I would like to see be different from the HIV model: We did not bring the case managers along in the science, so they were not able to offer the support to patients around understanding the disease and the importance of medication, because they were left out of the education. If you create a team, then all of them have to have the necessary information. In HIV, that is where we made some missteps; we kept the science separated from the prevention and services, and there was no interaction. The patient was better known by the people who knew the least about the disease itself and the benefits of treatment. Without that knowledge, how could those who have the confidence of the patient convince the patient of the importance of being treated? That is why we have people who are still not detectable, as well as the continuing struggles of being on multiple regimens, because the patients didn't get buy-in from the people that they trust.

Mr. Thompson: At the facility that I go to, Mount Sinai, the doctors work as a team. They all discuss the patient and reach a conclusion about where they are going with the patient and what their expected results are. They are very informative. I didn't know that I had stage 4 cirrhosis or that it could be stabilized. To me, stage 4 meant I was going to continue to decline. I didn't know that the liver repairs itself, and that with the elimination of the HCV infection the liver can regroup and reverse, to a point -- it's not going to be a completely healthy liver again. But I learned all of this from the doctors and the team where I get care. How well the doctors work together depends on the facility that you go to.

Dr. Lekas: With the massive restructuring of our healthcare system, this is a good note to end on. How HCV treatment will be integrated into this restructuring is an important issue. Thank you all.

A Home Run for Hepatitis C Treatment

Digestive Disease Week (DDW) 2014

HCV Antivirals: You Can't Tell the Players Without a Program

The rosters change almost daily, and new leaders emerge as the statistics accumulate rapidly. No, I am not referring to Major League Baseball; I am talking about antiviral agents used to treat hepatitis C virus (HCV) infection.

The past year has already seen the approval of new direct-acting agents and a change in recommendations.[1] And now, data from recent clinical trials have generated further excitement and promise -- that in the year of the 25th anniversary of its discovery, HCV can be cured.

At Digestive Disease Week (DDW) 2014, investigators updated attendees on the pace of progress in the discovery and validation of novel antivirals. The bottom line is that clinicians will soon have the option of using all-oral, interferon-free regimens that are highly effective against all HCV genotypes in all patients -- with "special population" designations no longer needed. There are clearly logistical details that will prove to be unique to each treatment regimen, and perhaps genotype-specific; however, these will be resolved with broader experience.

A Future Without Hepatitis C

But first, let's look at the not-so-distant past. An analysis presented at DDW indicates that overall treatment rates for patients with chronic HCV have been "dismally poor" and that treatment completion of both dual- and triple-therapy regimens -- pegylated interferon (pegIFN) and ribavirin (RBV) with or without a protease inhibitor, telaprevir or boceprevir -- is suboptimal in the real-world clinical setting.[2]

This comes at a high cost. Hasan and colleagues[3] reported that the cost of curing HCV genotype 1 with the triple-drug regimen was $125,000-$154,000. This estimate includes the associated costs of utilization of provider services, prescriptions, over-the-counter drug use, laboratory tests, and hospitalizations. These data indicate the need for simpler, safer, less expensive, and more effective options.

In the past month, a series of articles was published in the New England Journal of Medicine describing several new and different regimens. These strategies, based on an improved understanding of the HCV life cycle, have consistently produced rates of sustained viral response (SVR) of more than 90% after brief (8-24 weeks) periods of administration.

Accompanying editorials attest to the impact of these advances in treatment efficacy and safety, while highlighting the challenges presented by these "breakthrough medications." Chung and Baumert[4] state that "it may now be possible to imagine the global eradication of HCV infection"; however, they cite the need for early diagnosis and cost reduction, especially in low-income countries.

Jayasekera and colleagues[5] and Hoofnagle and colleagues[6] project that the use of these new agents will reduce the intensity of follow-up monitoring; the rate of hospitalizations for adverse effects; dependence on specialist care; and resource demands associated with disease progression, including those for liver transplantation and management of end-stage liver disease and liver cancer. However, with drug costs that may exceed $90,000 per course, it remains to be seen how these remarkable advances will extend to the estimated 150 million people with HCV infection living outside the targeted high-income markets for these agents.

Barriers to Care

Access to these medications is limited by case recognition. Recent recommendations for birth-cohort screening for HCV infection among US adults are predicated upon the belief that only a fraction of Americans with the infection has been diagnosed.

On the basis of data generated from a community-wide HCV screening project and a registry of known HCV patients, Kim and colleagues[7] calculated the proportion of more than 21,000 community residents with undiagnosed HCV infection. The overall prevalence was 2.2%; the age- and sex-specific HCV prevalence was highest (3.3%) in men aged 35-39 years and 45-49 years and lowest (1.0%) in women aged 30-34 years. Most had not been diagnosed.

These data support community-wide programs to institute birth-cohort-based screening as well as appropriate risk-based screening in individuals outside the birth cohort.

Antiviral Agents Soon to be Available

Although the results of multiple recent clinical trials have been reported, we will be unable to discuss all of the agents, studies, combinations, and screening and administration issues. I will therefore highlight a few strategies that have emerged.

Sofosbuvir-Based Regimens

Sofosbuvir (SOF) is a HCV NS5B nucleotide polymerase inhibitor. Several studies have demonstrated high SVR rates in patients with genotypes 1-6 infection treated with SOF combined with RBV with or without pegIFN for 12 or 24 weeks. High efficacy rates were demonstrated across many patient subtypes, including those considered difficult to treat (eg, HIV/HCV coinfection, treatment-experienced patients, and those with cirrhosis).

Many presentations at DDW 2014 described the efficacy and safety of SOF -- often used in combination with ledipasvir (LDV) -- without pegIFN. Subtle differences in response rates and ideal duration of therapy according to genotype were also reported, and these will ultimately be codified in guidelines.

Jacobson and colleagues[8] reported that the fixed-dose (single tablet) combination of SOF 400 mg/LDV 90 mg administered once daily for 12 weeks was highly effective and well tolerated in treatment-naive patients infected with HCV genotype 1, including those with cirrhosis. The addition of RBV did not enhance the SVR rate.

Kowdley and colleagues[9] reported that 8-week treatment with the fixed-dose combination regimen of SOF/LDV, with or without RBV, produced SVRs similar to those achieved with a 12-week regimen in noncirrhotic, previously untreated patients infected with HCV genotype 1.

Phase 3 studies[10] of SOF-based regimens have demonstrated high efficacy of this combination across genotypes, even in patients with multiple traditional negative predictors of diminished efficacy. SVR rates were somewhat lower in patients who had negative predictors; therefore, strategies focusing on addressing these hardest-to-cure populations may be required.

Patients who are considered more difficult to treat owing to advanced liver disease, genotype 3 infection, or previous treatment failure were studied by Gane and colleagues.[11] They reported that regimens involving SOF/LDV with or without RBV were efficacious in patients with more advanced liver disease and in those with previous treatment failure. In patients infected with the difficult-to-treat HCV genotype 3, the addition of RBV to SOF/LDV enhanced the SVR rate. The regimen was generally safe and well tolerated, with no additional safety issues in patients with decompensated liver disease.

Kwo and colleagues[12] reported that the SOF/LDV fixed-dose combination tablet can effectively be used to treat a population of treatment-experienced patients with HCV genotype 1 infection. The addition of RBV to the treatment, or extending the treatment from 12 weeks to 24 weeks, did not significantly increase the final SVR12 rates. Adverse events and laboratory abnormalities were more common in recipients of SOF/LDV with RBV and consistent with the safety profile of RBV.

Two additional studies documented successful retreatment.[13,14] In particular, the study reported by Nyberg and colleagues[14] included patients infected with HCV genotype 2 and genotype 3 in whom treatment had previously failed. Overall SVR rates were 100% for genotype 2-infected patients and 96% for genotype 3-infected patients after retreatment with SOF regimens for a longer duration.

Safety profile. In all of these clinical trials of SOF-containing regimens, adverse events and laboratory abnormalities were more common with pegIFN- or RBV-containing regimens, and SOF did not contribute to the frequency or severity of these expected events. Gordon and colleagues[15] also observed low rates of treatment discontinuation and no duration-related side effects.

Sofosbuvir was approved by the US Food and Drug Administration (FDA) in December 2013 for clinical use in the United States. Ledipasvir is not FDA-approved. On the basis of projections from Markov modeling and compared with current treatment regimens, sofosbuvir-based regimens should yield good future health outcomes and less liver disease complications and deaths across all genotypes, levels of treatment experience, severity stage, and coinfection status.[16]

ABT-Based Regimen

AbbVie's (North Chicago, Illinois) investigational HCV regimen consists of the following fixed-dose combination:

  • ABT-450 (an HCV NS3/4A protease inhibitor), 150 mg dosed with ritonavir 100 mg daily (ABT-450/r);

  • ABT-267 (a nonnucleoside NS5A inhibitor), 25 mg daily (ombitasvir); and

  • ABT-333 (a NS5B RNA polymerase inhibitor), 250 mg twice daily (dasabuvir).

This 3-drug (3D) regimen is administered with or without weight-based RBV. The multitargeted antiviral combination with 3 different mechanisms of action interrupts the HCV replication process, with the goal of optimizing SVR rates across different patient populations.

At DDW 2014, several investigators presented the results of clinical trials of this regimen. Kowdley and colleagues[17] conducted a double-blind, placebo-controlled study in noncirrhotic, treatment-naive patients with chronic HCV genotype 1 infection. Patients were randomly assigned to receive the coformulated 3D regimen or matching placebo for 12 weeks.

The intention-to-treat SVR12 rate for active drug recipients was 96%; on-treatment failure and post-treatment relapse occurred in 0.2% and 1.5% of patients, respectively. The most common treatment-emergent adverse events were fatigue and headache (approximately 30% each); discontinuation as a result of these events occurred in 0.6% of patients in each arm.

The interferon-free, 12-week 3D regimen was also effective in noncirrhotic, treatment-experienced, genotype 1-infected patients, a group typically associated with the lowest response rates.[18] The 3D plus RBV regimen led to an SVR12 of 96%.

Andreone and colleagues[19] also reported that a 12-week regimen of ABT 450/r/ABT-267 and ABT-333 with or without RBV achieved high rates of SVR12 (97% with 3D plus RBV, and 100% with 3D alone) in treatment-experienced patients. The regimen was generally well tolerated, as evidenced by the low rate of treatment discontinuation and serious adverse events.

In a phase 3 study of an all-oral, interferon-free regimen exclusively in HCV genotype 1-infected patients with compensated cirrhosis, treatment with 3D and RBV resulted in high rates (92%-96%) of SVR12 in both the 12- and 24-week treatment arms.[20]

This highly effective, well-tolerated, 3D HCV regimen is under FDA review.

Other Regimens

Another all-oral, ribavirin-free, interferon-free combination of 3 direct-acting agents -- daclatasvir (an NS5A inhibitor), asunaprevir (an NS3 inhibitor), and BMS-791325 (a nonnucleoside NS5B inhibitor) -- was shown to induce SVR12 in 92% of treatment-naive patients with chronic HCV genotype 1 infection.

Hassanein and colleagues[21] report that 12 weeks of the all-oral treatment combination achieved SVR12 in all noncirrhotic patients with genotype 4 infection, with no virologic failures. These results extend the potent antiviral activity of this regimen to patients with HCV genotype 4 infection, while maintaining the positive tolerability and safety profile documented previously in patients infected with genotype 1. The investigators state that the rapid attainment of SVR suggests that perhaps an even shorter duration of therapy or elimination of 1 of the agents in the combination may be as efficacious.

This regimen is not FDA approved.

Enhancing the Outcome

It was reported that statin use is associated with SVR in patients with HCV treated with pegIFN and RBV, independent of host metabolic factors.

Sanchez and colleagues[22] used the Veterans' Affairs Clinical Case Registry to conduct a retrospective cohort study of veterans infected with HCV genotypes 1, 2, and 3 who received treatment between 2002 and 2008. They found that continuous statin use was associated with increased SVR that persisted after adjustment for age, race, sex, body mass index, genotype, diabetes, hypertension, fibrosis, and high-density lipoprotein and low-density lipoprotein cholesterol levels. Although the mechanism responsible for this observation was not defined, it is known that statins have antiproliferative, antiangiogenic, and anti-inflammatory effects on hepatic cells.

Further studies are warranted to explore whether statin use will significantly reduce progression of liver fibrosis in patients with advanced chronic HCV infection treated with the new antiviral regimens.

A Final Note

Coffee drinking has been associated with a reduced risk for progression to cirrhosis and hepatocellular carcinoma. The mechanism is unclear, but caffeine has been proposed to have antifibrotic and antineoplastic effects.

Among HCV-infected veterans, overall coffee intake (but not decaffeinated coffee intake) was inversely associated with advanced fibrosis.[23] Coffee intake was higher in those with mild fibrosis compared with advanced fibrosis, although none of the comparisons were significant because of the sample sizes. In multivariate analysis adjusting for age, diabetes, alcohol use, obesity, and soda consumption, the inverse association between the number of daily cups of coffee and advanced fibrosis persisted.

So, have a cup of coffee -- it will help us to stay alert as we wade though the continually emerging and voluminous, yet exciting, data on the cure of HCV infection. We eagerly await the next inning.

Abstract

Hepatitis C infection is an important problem in inner city neighborhoods, which suffer from multiple health disparities. Important factors in this population include alcoholism and substance abuse, mental illness, and homelessness, which may be combined with mistrust, poor health literacy, limited access to health care, and outright discrimination. Systemic barriers to effective care include a lack of capacity to provide comprehensive care, insufficient insurance coverage, poor coordination among caregivers and between caregivers and hospitals, as well as third party payers. These barriers affect real world treatment effectiveness as opposed to treatment efficacy, the latter reflecting the world of clinical trials. The components of effectiveness include efficacious medications, appropriate diagnosis and evaluation, recommendation for therapy, access to therapy, acceptance of the diagnosis and its implications by the patient and adherence to the recommended therapy. Very little attention has been given to assisting the patient to accept the diagnosis and adhere to therapy, i.e., care coordination. For this reason, care coordination is an area in which greater availability could lead to greater acceptance/adherence and greater treatment effectiveness.

Hep

from Jules: Reinfection is a big barrier to care for several reasons not discussed in the study. Recent studies report high reinfection rates for both IDUs and sexual transmission/MSM, treaters use this as a reason all too often to not treat but it is a real concern, no one wants to spend resources & then a patient continues with risky behavior & gets reinfected not once but several times after several courses of pretreatment. So education to patients & case managers about reinfection is crucial. Screening & care is an opportunity to provide education about reinfection & a continuum of followup may be helpful to help assure these vulnerable populations are not reinfected. As well, in the past very often IDUs are not welcome in clinicians offices & are considered not treatable, so they did not get treated, this has to be addressed, there is a stigma & bias by the healthcare system & clinicians that IDUs should not be treated & often they are not welcome in the clinicians office. The IDU plays a role, they can be difficult to deal with, contentious, hard to communicate with, there are concerns about their adherence, alcohol & drug use. But these barriers can & should be addressed, resources are needed, and this applies as well to incarcerated, homeless & mentally ill, who each have a set of not dissimilar barriers. Healthcare facilities that are capable of treating these patient populations must be available & linkage to care must be provided.

from Jules: these barriers reviewed in this article are well known and common. You can see the focus groups for the study were conducted in NY & SF where HCV care & treatment access as well as screening is probably better than most other cities throughout the USA, underscoring the need to (1) establish easily accessible HCV screening sites, (2) intensified public awareness, advertising campaigns are needed to inform the public of HCV, why they should be screened, where they can be screened (DOH/public Hotlines in every city are needed), (3) easy linkage to care is needed for all infected groups, (4) good patient education, easy to understand, about the HCV disease, how it affects a person, how to understand why they should be treated, what treatment consists of, (5) improved communications between clinicians to patients is strongly needed, (6) case managers at screening sites to help with patient eduction, support & linkage to care & followup, (6) its important to communicate the new treatments vs old treatment & the ease of these treatments: IFN-free, 12-24 weeks, little or no side effects, patients need to be educated about the BENEFITS & OUTCOMES of a cure. Every city should have a publicly supported hotline, run by the DOH, or a community group/coalition that has the resources, capacity, skills, knowledge to provide the needed services which include 24/7 hotline, nurses on-call, linkage with screening sites, care centers, support services. Clearly Mayors' offices, State offices, public officials need to be brought on board to assist in this effort. Also helpful to bring in are local groups in large cities well known in the marginalized HCV affected communities to help form a coalition to support the services described above.

Abstract

Background

Illicit drug users have a high prevalence of HCV and represent the majority of newly infected persons in the U.S. Despite the availability of effective HCV treatment, few drug users have been evaluated or treated for HCV. Racial and ethnic minorities have a higher incidence and prevalence of HCV and higher HCV-related mortality. Factors contributing to poor engagement in care are incompletely understood.

Methods

Fourteen mixed-gender focus groups of either African American or Latino/a drug users (N = 95) discussed barriers to HCV testing and treatment. Themes were identified through content analysis of focus group discussions.

Results

Many drug users were tested for HCV in settings where they were receiving care. Outside of these settings, most were unaware of voluntary test sites. After testing HCV positive, drug users reported not receiving clear messages regarding the meaning of a positive HCV test, the impact of HCV infection, or appropriate next steps including HCV clinical evaluations. Many drug users perceived treatment as unimportant because they lacked symptoms, healthcare providers minimized the severity of the diagnosis, or providers did not recommend treatment. Mistrust of the motivations of healthcare providers was cited as a barrier to pursuing treatment. Social networks or social interactions were a source of HCV-related information and were influential in shaping drug users perceptions of treatment and its utility.

Conclusion

Drug users perceived a paucity of settings for self-initiated HCV testing and poor provider-patient communication at test sites and during medical encounters. Notably, drug users reported having an unclear understanding about the meaning of a positive HCV test, the health implications of HCV infection, the importance of clinical evaluations and monitoring, and of treatment options for HCV. Efforts to improve the delivery of clinical messages about HCV infection for drug users at test settings and clinical encounters are needed.

Background

\Hepatitis C virus (HCV) is a blood-borne infection most efficiently spread via direct parenteral exposure through non-sterile injection practices [1-4]. The World Health Organization estimates a global prevalence of HCV of 2%, or 123 million people [5] most of whom are chronically infected. HCV is the most common chronic blood borne infection in the United States and worldwide, and accounts for roughly one quarter of all cases of cirrhosis and hepatocelluar carcinoma [6,7]. HCV is hyperendemic among people who inject drugs, representing the largest group of infected persons both worldwide, and in each country where HCV prevalence and risk factor data are available [8-10]. The estimated global prevalence of HCV among IDUs ranges from 9.8% to upwards of 97%, with most estimates falling between 50-90% in regions with long-standing endemic injection drug use [1,4]. The incidence of HCV among IDUs ranges regionally from 10 to 40 per 100 person-years at risk [1,11]. HCV is also transmitted sexually among men who have sex with men, often in association with non-injection illicit drug use [12,13].

HCV causes chronic infection with persistent viremia in the majority of those infected (~85%) [14]. As a result, chronically infected persons constitute a significant reservoir of HCV creating an environmental transmission dynamic that increases the probability that a non-sterile injection episode will be with a chronically HCV-infected person [1,11]. Important sequelae of chronic HCV are liver fibrosis leading to cirrhosis; liver failure; and hepatocellular carcinoma [15]. Studies suggest that over the course of two decades, 20-30% of chronically HCV infected persons will develop cirrhosis, with an estimated 10,000-20,000 early deaths [14]. In the United States, the disease burden is predicted to increase up to 3-fold over the course of the next 10-20 years [15]. The efficacy of HCV treatment has improved in recent years with the introduction of direct-acting antivirals (e.g., telaprevir and boceprevir) and the prospect of interferon-free regimens [16,17]. For many, fear of adverse effects of HCV treatment is a barrier to treatment initiation and may contribute to treatment non-adherence and treatment discontinuation [18-21]. While HCV treatment has the potential to cure the virus in 40-80% of patients, current treatment is arduous, lengthy, expensive and remains inaccessible for many drug users [15]. The majority of drug users remain out of HCV care, and few are engaged in treatment [18,21-24]. Many HCV positive drug users have not been evaluated for HCV treatment; are less likely to see an HCV specialist or to get an HCV RNA polymerase chain reaction (PCR) test to document chronic active infection; and are less likely to be receiving antiviral treatment for HCV compared to non-injection drug users [18,21,25]. Active drug use has been shown to not have a direct, negative effect on treatment efficacy [8,9,26-28]. It is estimated that less than half of drug users with chronic HCV have been offered treatment ever [17].

Racial/ethnic minorities are less likely to receive anti-retroviral therapy for HIV [29,30]. Some prior qualitative studies have highlighted drug users' misconceptions and lack of understanding about HCV, racial and ethnic minorities have a higher incidence and prevalence of HCV and higher HCV-related mortality [18,31-35]. Drug users often have limited access to health care and may experience or perceive stigmatization that poses a barrier to care [23,35]. Additionally, some drug users report that drug use-related stigma is a barrier to HCV testing. Rates of HCV are higher in racial/ethnic minority drug users [36]. Further data to inform the delivery of clinical messages about HCV infection for drug users at test settings and clinical encounters are needed. This study sought to explore racial/ethnic minority drug users' attitudes, perceptions, and experiences regarding HCV and HIV testing, referrals and treatment, through focus groups with drug users in San Francisco and New York City. This paper presents data regarding HCV testing and care.

Methods

Study participants

Fourteen focus groups with a total of 95 participants were conducted in New York City (6 focus groups) and San Francisco (8 focus groups) in three recruitment settings: HIV primary care clinics, methadone maintenance treatment (MMT) programs and syringe exchange programs (SEP). During the course of the study, the HIV clinics both conducted HCV testing and the site in NYC provided on-site HCV treatment; the MMT programs offered anti-HCV testing, but neither viral load testing nor HCV treatment; and the SEPs did routinely offer HCV testing but offered no on-site HCV care. Eligibility criteria required that participants be 18 years of age or older; self-identify as African-American or Latino/a; and be receiving services at one of the recruitment sites. Participants were excluded from the study if they had severe cognitive impairment, suicidal ideation, or active psychosis. The study included persons who have used illicit drugs in the past 12 months by either injection or non-injection routes; non-injection illicit drug users were included because of data demonstrating rates of HIV in non-injectors comparable to injectors in many cities [3] and because of concerns of HCV transmission via drug using paraphernalia and networks [1]. The terms 'drug users' and 'injection drug users' (IDUs) are used throughout the text where appropriate. This manuscript reports on findings with respect to HCV testing and treatment. This study was approved by the Institutional Review Boards of Beth Israel Medical Center and the University of California, San Francisco.

Participants were recruited through staff referrals at each of the recruitment sites regardless of HCV status or prior testing experience. Participants were told that the goals of the focus group were to explore participants' experiences with HIV and HCV testing and care. The number of participants in each group ranged from 3 to 12. All focus groups were of homogenous race/ethnicity, consisting of either Latino/a or African American participants. The rationale for race/ethnicity specific focus groups was to identify possible race/ethnicity specific issues with regard to HIV and HCV testing and care. All focus groups were conducted in English. Participants provided informed consent and were reimbursed $25 for their participation in the study.

Focus groups were conducted by PhD-level qualitative researchers, bi-lingual in English and Spanish; each group lasted roughly 90 minutes. The focus groups used a semi-structured qualitative interview guide designed to explore, in-depth, the following specific thematic areas related to HIV and HCV including: self-perceived risk; general knowledge of the viruses; prior experiences and current feeling about seeking testing; prior pre- and post-test experiences; and prior experiences accessing or remaining engaged in treatment. Further, the interview guide also included open ended queries about individual's drug use histories, knowledge of their own HIV/HCV status, and perceptions about race/ethnicity in relation to testing and care (the focus group guide is available from the corresponding author). Participants recruited for these focus groups were not tested serologically: those recruited from HIV clinics were known to be HIV infected; for others HIV status was by self-report; and for all, HCV status was self-reported. 39% reported HIV infection (21% of the total reported HCV/HIV co-infection), 36% reported HCV mono-infection, and the rest reported unknown status. All focus groups were audio taped and transcribed verbatim.

Qualitative data analysis

Transcripts were coded and analyzed using Atlas.ti V.5 software. At least two researchers individually reviewed and independently coded all transcripts and discussed ambiguities. Grounded theory [37] analytic techniques were used to seek patterns in the data and to develop emergent hypotheses about them. Analysis began by coding verbatim references containing any of the following codes: HCV/HIV testing, access to HCV/HIV care, HCV/HIV treatment, racial/ethnic minority status, co-infection and drug user status. Two emerging codes were added during the analysis: "medical mistrust" and "stigma".

Results

Fourteen focus groups were conducted, 6 in NYC and 8 in San Francisco. The 6 in NYC included one with Latino/a participants and one with African American participants at each of the three recruitment settings (MMT, SEP, and HIV clinic) with a total of 51 participants. The 8 in San Francisco included 2 with African American and 1 with Latino in MMT; 2 Latino and 1 African American at HIV primary care; and 1 African American and 1 Latino at SEP, with a total of 44 participants. The total sample of 95 participants was 41% female (n=39); average age was 45 years (minimum 32, maximum 58). The analysis discusses results related to access to HCV testing, post-test counseling and medical care, experience with HCV treatment and perceptions of HCV treatment. No differences between testing experiences emerged by gender or between focus groups in NYC and San Francisco hence, results are reported in aggregate.

HCV testing

In focus groups, nearly all participants reported having been tested for HCV. Participants generally described an HCV testing experience that consisted of testing at the structured settings in which they were receiving care, with tests commonly having been initiated by health care providers with knowledge of participants' risk factors for HCV. The primary settings in which participants were tested for HCV were MMTs and SEPs. Common to those who were or had been in MMT was a perception that routine HCV testing was a mandatory component of the intake exam and annual physicals for all MMT patients: "You're on methadone, it's a requirement anyway, to get tested for [HCV]" (African American male); no one reported objecting to being tested for HCV in this way. This perceived routinization of HCV testing was also reported by participants who underwent testing at health care sites where tests were usually initiated by health care providers and where the reason for the appointment was to receive care for other illnesses: "I did [HCV] testing when getting [treatment for] pneumonia" (Latino). Such testing often took place without participants being aware that they were tested for HCV: "I found out afterwards [that I was tested for HCV]. [The doctor] tested it on his own". (Latino).

While testing for HCV was common among focus group participants, most reported being unaware of voluntary testing sites. Most participants were eager to have access to voluntary HCV testing. Focus group participants did not report seeking self-initiated HCV testing outside of MMT, SEP, jail and HIV primary care settings: "Most people just don't know where to do it [HCV test], unless you go to the exchange and they happen to be doing it there" (African American male); "You have to find a way to get it [HCV test]; It ain't like-come and get a hep C test. It's like a best-kept secret" (African American male).

Underscoring the reality that HCV is a widely asymptomatic disease, only one participant reported seeking medical attention because they experienced symptoms associated with an HCV infection: "I had yellow jaundice. Like my urine was orange, real dark orange [...] At least the doctor told me [I was HCV positive]" (African American female).

These patterns of HCV testing experiences contrasted with participant reports regarding HIV testing, which were characterized by frequent and self-initiated testing with access to ubiquitous testing sites: "HIV testing is much more accessible to me, more accessible than hepatitis C" (African American female). Participants had a high degree of awareness of available HIV testing sites: "The fact that they're so accessible, I feel like if any day I feel like getting up and going to get [an HIV] test, I can get it the very same day" (Latina). Many participants reported self-initiated HIV testing every three to six months.

Experiences with HCV post-test counseling and referrals

Despite their individual histories of drug use, many participants were surprised when they were first diagnosed with HCV: "My doctor took blood, and he tested it and he told me I had hepatitis C, and that was my first time knowing about it [...] I was an injector". (African American male)

Many participants found to be HCV positive reported receiving their results but coming away from post-test counseling without a clear understanding of the significance of the diagnosis or what next steps to take: "I found out I was hep C positive. [The doctor] told me the basics but they never really told me what the next step was". (Latino) Participants reported confusion and uncertainty given their new situation: They had been given a diagnosis of HCV, but did not come away with a clear understanding of the health implications or what to do next:

You're hep C positive, but now what? they should have a place to send them or I should have somebody some place at my facility to at least counsel them. Nobody has even spoken to them. (African American male)

They won't refer you to nobody, see they just told me and just left me hanging. Just left me there. (African American female)

They didn't give me nothing to go on. I had nothing to take home with me and sit down and study and go over myself... they don't have nothing for the poor person that has contracted hep C. Nobody where I got tested at gave me any literature. (African American female)

Accompanying the feelings of uncertainty regarding an HCV diagnosis, many participants described feeling fatalistic with a generalized nihilism about managing their infection: "I don't know what to do. Except just walk around dying from it" (African American male).

Participants specifically described a lack of explanation and clarity regarding the treatment options for HCV and they were eager for more information and a better understanding of HCV treatment: "When I first found out I had hepatitis C, they didn't suggest any kind of treatment. It was only two or three years later that they made me an appointment for the hospital to go" (Latina). As part of this uncertainty about treatment, many people came away with an implicit message that there was not much else that could or needed to be done to treat HCV or to prevent liver damage. As one participant explained: "Everybody says there's really nothing too much to do when you got that [HCV]. They just say, yeah, I got it, as far as hep C, and they [health care providers] just let you know" (African American male). Participants also reported disengaging from care once they found out they weren't eligible for treatment or that treatment wasn't necessary for them at that point in time.

So he told me that if you want, take a biopsy if you want it, that was my option. So I didn't do it. He said, but your liver seems like it's okay. The numbers are in a good-good place [...] So I dropped it at that. (Latino) Some participants, despite having been told they were HCV positive, did not believe they were infected because their providers did not offer them treatment: "I don't believe them [the doctors] for the simple fact they didn't give me, they didn't give me no medicine for it [HCV]"; "I'm sure he will if I have hep C, he will tell me take this and this medication. He will order it. So I do not believe I have hep C" (African American male).

Experiences with HCV treatment evaluations

Among participants who reported receiving HCV treatment evaluations, many said that they were told by health care providers that due to the healthy state of their liver and the results of various tests to assess their infection, treatment was not recommended at that time. Some understood that treatment was not offered because there was no evidence of liver damage. Many participants reported not initiating HCV treatment because their providers either did not discuss or recommend it: "My doctor told the same thing that everything was fine, not to worry about it [HCV] [...] that the numbers were low and that I didn't need no medication or anything" (Latina); "[My doctor told me] I didn't need a treatment because it wasn't bad [...] My liver wasn't inflamed, and I was doing okay [...] there was no need for medication until years down the line" (African American male).

While some people came away from HCV evaluations understanding that treatment was indicated if there was substantial liver damage and may not be otherwise necessary, many participants did not have a thorough understanding and felt as if they were left in limbo with a positive diagnosis without clear options. Participants who were evaluated but not offered treatment commonly reported being counseled about reducing drug and alcohol use and avoiding excess acetaminophen, "[the doctor] told me that [...] just don't drink any alcohol and don't abuse them, stuff that's going to irritate the liver". (Latino) There were few participants who reported being encouraged to have regular medical follow-up to monitor their HCV infection but without recommendation for treatment.

I went according to my doctor. He said that my viral load was okay, so I tookÑI took it like that, okay, so then I'm fine. Every month, you go see that doctor [...] on a monthly basis and stayÑstay with blood work. (Latino) Few participants in the focus groups had initiated HCV treatment; however, of those who reported initiating treatment, they all discontinued treatment due to adverse drug reactions.

I decided to treat it [HCV] [...] I only did it for like four months because I ended up getting some side effects [...] The medication was doing things that I dislike [...] I told [my doctor] that I am not taking it anymore. (Latino) For the participants who reported being offered treatment, many reported that the low odds of eradicating the virus deterred them from initiating treatment. Additionally, one participant reported that their provider did not recommend treatment saying the patient was infected with an HCV genotype that was poorly responsive to treatment.

Perceptions of HCV treatment

Knowledge and perceptions about HCV treatment often came from peers, and the messages communicated were often discouraging of treatment. While a few patients had previously initiated HCV treatment, most had no direct treatment experience. Participants reported that these communications with peers raised anxiety about the potential adverse side effects of the medication: "I didn't even know what the process was [...] I found out through someone who had hep C, and her experience through it" (Latino).

Participants with HCV were uniformly eager to learn more about HCV treatment and how to stay healthy. Among participants who reported discussing treatment with a health care provider, or who were offered treatment, the majority felt dissuaded from pursuing it. While some participants reported an interest in treatment, the consideration of "everything that goes with it", including not wanting to endure the serious side effects of treatment, was the primary reason that participants chose not to initiate treatment. Among HCV-positive individuals in particular, there was a common perception that HCV treatment was worse than the disease due to the difficulty in coping with the length of treatment and medication side effects: "[There are] bad reactions that a lot of people have with medication. Some people get suicidal, depression [...] They'd get lonely, you know, depressed, big, big stay of depression" (Latino).

Many participants while willing and even eager to consider HCV treatment, many articulated that these fears of lengthy treatment and severe adverse effects- discouraged them from pursuing treatment. Additionally, participants reported believing that treatment might be harmful to their liver, might cause HCV infection or other harmful physical adverse effects, and be inefficacious: "Interferon I've heard is the treatment for it but I've heard that the treatment is worse than the disease and it's not effective". (Latino) Such concerns lead many infected but asymptomatic participants to not seek treatment; as one participant explained it: "if it ain't broke, don't fix it" (African American male). This attitude was common; participants reported believing that it was more advantageous to their health to not seek treatment rather than pursue treatment and risk making their health worse: "my liver function is still good, so I'm not going [to] take something that's going [to] make me worse" (Latino). In contrast, across focus groups, participants' overall knowledge about HIV and treatment options was extensive, regardless of their HIV status. Participants understood opportunistic infections; various tests indicating HIV/AIDS status; treatment outcomes; and the necessity of treatment to control the infection "If you're told you got HIV [...] it's not like before, like it's more manageable, you can live longer [...] there's so many drugs that can help with it". (Latina) In addition to their individual concerns about HCV, participants also regarded HCV as a virus infecting and affecting drug users rather than non-drug users. They concluded that the paucity of HCV services and the lack of effective treatment options were the result of stigma and marginalization of IDUs. In addition, participants described their belief that socioeconomic factors and insurance availability influenced their doctors' decision making regarding the provision of HCV treatment.

If you have private insurance [...] They'll give you all the treatment and health that you want...but because they know that Medicaid is not going to pay them their money on time- they're going to get paid [...] they're not ready and willing to offer this treatment [to those with Medicaid]. (Latino)
I think a lot has to do with - people who - the powers that be don't use drugs like we use drugs. It [HCV] don't affect them. (African American male) One participant explained that she felt mistreated by her doctor: "They kick you to the side". (African American female)

Mistrust of health care providers' motivations manifested in other ways. Some participants reported believing that their providers were diagnosing, and even misdiagnosing HCV to receive insurance payments for their visits.

Implications of drug use

One of the barriers participants reported complicating engagement in HCV care was active drug use. Participants reported that when they were using actively they were less likely to get tested for HCV, "Personally, I wouldn't put down no syringe [...] to go get tested [for HCV]" (Latino); "It took me so long [to get tested] because I was getting high". (Latino) One participant explained that her commencing HCV care occurred "fast as my addiction would let me go". (African American female) Active drug use not only emerged as a barrier to participants' willingness to engage in HCV testing, but also as a barrier to clinical follow-up after receiving a HCV diagnosis. Participants reported that the consuming nature of drug use precluded any motivation to seek care. One participant attributed his active heroin use to his inability to schedule an appointment for an HCV evaluation from a referral he received after being tested for HCV:

Yes, [the doctor] told me ... numerous times. I just didn't do it. Either I forgot about it or was just too lazy to get up off my ass and go do it. I got a thing about keeping appointments [...] it's the dope's fault. (African American male)

Discussion

It is estimated that about 60-90% of drug users are infected with HCV [14,38,39]. Focus groups with drug users in MMT, SEP and HIV Primary Care reveal that prior to a diagnosis of HCV, most participants had a poor understanding of HCV and its significance. After being diagnosed, many participants reported not receiving a clear message regarding what the infection meant; their HCV status; and next steps, including follow-up evaluations and the availability, role and efficacy of treatment options. Participants also reported some mistrust of health care providers, recognizing that active drug use is a barrier and commonly reported not receiving referral for HCV clinical evaluation after receiving a positive test result.

Many drug users come into contact with drug treatment programs and/or drug related services such as needle exchange. These programs serve as important points of access for health services. In focus groups discussions, participants explained that programs for drug use served as primary settings in which they received HCV testing. SEPs and MMTs along with other clinical settings were structured settings in which participants reported receiving HCV testing. Our findings underscore the importance and utility of providing HCV testing in drug treatment programs or programs aimed at serving drug users. In our sample the majority of drug users had reported receiving at least one HCV test in the past; this has not been the case in all previous studies [35,39]. This may relate to participants' having been recruited in clinical or harm reduction settings.

In contrast to ready access to voluntary HIV testing, participants in our study reported limited access to voluntary HCV testing. Participants in numerous studies reported feeling most comfortable accessing HCV testing and HCV-related services at sites where providers had an understanding of addiction and were accustomed to and respectful of drug users [15,40]. In our study, participant comments also suggested that in the health care systems they accessed, there were few settings available for voluntary HCV setting (e.g., mobile HIV testing but no HCV testing vans). In this way, and in the learned experience of our focus group participants, offering both targeted and voluntary testing at sites where drug users are already receiving services, in settings widely populated by drug users, could serve as effective points of entry for drug users to initiate and maintain care for their HCV infections.

Overall, participants reported a gap between testing and receiving referrals to medical evaluations following a positive HCV test result. Many publications document low rates of referral after testing positive [27,34,35] but it is usually assumed that this gap is due to patient non-adherence; our data demonstrates drug users perceive not having had received referrals. Participants reported feeling abandoned by clinicians, a finding that is consistent with other studies of HCV testing among drug users [15,41]. It is important to note that the same barriers that participants identified may also contribute to provider reluctance to initiative HCV treatment for drug users, however, several studies have highlighted that with appropriate attention to these issues, active drug users can be successfully treated for HCV [9].

Most participants in our study were unclear about how HCV infection should be evaluated and monitored, and about treatment. Some participants also perceived HCV treatment as something available to the wealthy and not to marginalized groups or those on Medicaid. Others were suspicious that HCV was diagnosed and treatment offered more for profit than to improve the health and well-being of patients. It is difficult to know whether these perceptions were based on a lack of understanding of HCV infection and treatment (a knowledge deficit) versus based primarily on emotional factors such as medical mistrust. The former would be amendable to educational efforts while the latter would require being addressed by other intervention strategies.

The fact that focus group participants reported relying heavily on peers for HCV treatment knowledge suggests that support from peers may be a valuable way to engage drug users in HCV care. This finding is consistent with qualitative studies that have been published on this topic [15,40]. This peer-gained knowledge of HCV and its treatment is maintained through peer relationships.

These forums serve a critical role in disseminating information about HCV to those either untreated, out of care or who have not received adequate information from their providers [8].

The findings presented in this paper should be interpreted with some caution as reported experiences may not be generalizable to all drug users in all settings. It is possible that the focus group framing or even the nature of discussing these issues in a group setting may have led to reporting bias. There may also be other factors that did not emerge in the discussions. Due to the design of the study, for those participants recruited at sites other than HIV clinics, HIV status was my self-report and for all participants HCV status was self-reported. Further, we could not confirm self-reports of prior testing and it is therefore important to note that what patients reported were their perceptions and memories. Also, it is impossible to discern the extent to which HCV treatment was medically necessary for the HCV-positive focus group participants. The data collected through focus groups are qualitative and further quantitative survey data about the proportion of DUs having positive, neutral, or negative experiences would be valuable. Further, these focus groups were conducted during 2008-2009 and issues of awareness and access may have changed; however, the availability of improved therapies only increases the need to have clear understandings of potential barriers. Finally, due to funding limitations, 1) focus groups were not conducted with white drug users, which would have been useful for comparison; and 2) only English-speaking drug users were eligible for this study, and therefore our findings may not reflect those of non-English speaking drug users.

HCV remains a critical public health challenge among drug users, and the numbers of deaths due to HCV have surpassed those due to HIV/AIDS [42]. A recent meta-analysis has demonstrated that a sustained virologic response after treatment is associated with a reduced incidence of hepatocellular carcinoma underscoring the importance of engaging HCV infected patients in treatment [43]. HCV is a major cause of preventable morbidity and mortality among IDUs; scaled-up efforts to prevent HCV are imperative. Efforts to increase or establish HCV surveillance as well as the development of comprehensive and effective strategies to reduce transmission among IDUs are urgently needed. Public health approaches to HCV may benefit from expanding access to and awareness of voluntary HCV testing sites and treatment services. Standardized post-test counseling messages and active referral are critical in efforts to promote stronger linkages between HCV testing and care. Concrete, active referral linkages may also be needed [44]. Additionally, as with the Seek, Test, and Treat strategy being employed to reduce population HIV rates, programs targeted at increasing rates of HCV treatment among drug users might be an important strategy to reduce the number of HCV-positive persons, thus reducing both overall risk to individual drug users and reducing HCV prevalence at the population level.

from Jules: authors told me this study was conducted during the time period for pegylated interferon+ribavirin use. So for me a question is will these same barriers persist and to what degree if they do after new improved therapies about to be approved are available. In addition there are other barriers not addressed in this poster so how much will these barriers create difficulty in accessing care & treatment. Of course the barriers to initial diagnosis are the first concern, how will we diagnose the 75% we think are undiagnosed in the USA, estimated to be as many as 5 million undiagnosed. Second, how will we develop an adequate care infrastructure capable of accommodating so many patients, and will this care system be effective with adequately qualified care providers. I have doubts that primary care & untrained providers with no experience in hepatitis C can be trained to treat the disease. Third, how will we accommodate the hardest to treat patient populations: marginalized patient populations, IDUs, this will not be easy as this will take commitment to build a healthcare infrastructure with the ability to provide the specialized resource-intensive these patient populations will need. And within the IDU community there are gradations of difficult-to-treat patients, in particular there are patients that most providers do not want to treat, these are the most marginalized IV drug users who the healthcare system does not want to treat, they can be dirty, homeless, using IV drugs & alcohol, have psychiatric disorders, poor communication skills, unable to navigate healthcare system, mistrusting of the healthcare system, uneducated, but want to be cured, so we need to create a system that can & will treat these patients, it is doable. We can create a successful healthcare facilities system for them, we have to be creative.

More than 90% of patients with HCV infection at an academic primary care practice got referred to a hepatitis specialist [1]. But for most patients more than a year passed between HCV diagnosis and referral, and only 18% of patients with a documented specialist visit started anti-HCV therapy.

Prompt diagnosis, referral, and possibly treatment of HCV infection are essential to preventing complications. Rapid referral and treatment might be considered even more urgent since licensing of direct-acting antiretrovirals that could induce sustained virologic response in more people. To assess HCV referral and treatment rates in their academic primary care practice, investigators at Baystate Medical Center/Tufts University in Massachusetts conducted this retrospective cross-sectional study. The researchers aimed both to describe referral and treatment patterns and to identify traits that favored or delayed referral and treatment.

The study focused on people making one or more office visits in the past 2 years who were diagnosed with HCV and not already in care with an infectious diseases or HCV specialist. Among 235 people eligible for the study, 215 (91.5%) got referred to a hepatitis specialist and 20 did not. But among those 215 referred patients, only 146 (68%) had a documented visit with an HCV specialist. Among the146 people with a documented specialist visit, 26 (17.8%) got treated for HCV infection and 120 did not. Among treated people, median time from referral to starting therapy was 226 days (interquartile range 157 to 376).

Among the 120 people not treated after a documented HCV specialist visit, reasons for lack of treatment included loss to follow-up, patient preference, psychiatric factors, substance abuse, and undetectable HCV load. Among the 20 patients with an HCV diagnosis not referred to an HCV specialist, (overlapping) reasons for lack of referral were active substance abuse (9 people), patient preference (7), psychiatric disorders (6), and other reasons (4).

Compared with the 146 referred people who had a documented HCV specialist visit, the 69 who did not were less likely to be married (5.8% versus 28.7%, P < 0.01) and marginally less likely to have any comorbidity (17.4% versus 29.7%, P = 0.07) or to be HIV-positive (4.4% versus 11.9%, P = 0.13). In this analysis, gender, race, age, injection drug use, psychiatric conditions, and severity of HCV infection did not distinguish between patients who did and did not have an HCV specialist visit.

Median time from HCV diagnosis to specialist referral was 411 days (interquartile range 33 to 1390). Time-to-event analysis identified three factors that favored a shorter median time to referral: being married (71 versus 184 days, P< 0.001), being HIV-positive (66 versus 156 days, P = 0.045), and having any comorbidity (83 versus 179 days, P = 0.009).

The researchers suggested the high referral rate reflects a practice setup in which primary care and specialty services share electronic medical records and ancillary staff. The correlation between being married and prompter referral may mean marital status is a proxy for social support that could enhance adherence. The link between HIV coinfection or comorbid conditions and faster referral may reflect more frequent clinic visits by these patients and thus increased provider awareness.

The investigators called for prospective studies to confirm their findings. They suggested that new, simpler, less toxic HCV regimens may prompt faster patient referral and treatment initiation.

Program Abstract

Background: Hepatitis C virus (HCV) infection is a common blood-borne disease in the United States; approximately 3.2 million people are infected chronically. Prompt evaluation for possible treatment is important to avoid complications of HCV infection.

Methods: This was a retrospective cross-sectional study at an academic primary care practice. The objectives were to describe referral and treatment patterns of HCV infection and identify patient characteristics associated with delay in HCV care. HCV-infected patients were identified based on ICD-9 billing codes.

Exclusion criteria included missing electronic medical records and patients followed by a HCV specialist prior to their initial presentation to our practice. Patient characteristics associated with delay in HCV care were determined using time-to-event methods. Differences were evaluated using Kaplan-Meier plots and log-rank tests.

Results: Two hundred and thirty five patients were included, of which 215 were referred to a HCV specialist. Mean age was 50 years. Sixty four percent were male and fifty six percent were white. Median duration from HCV diagnosis to referral to HCV specialist was 411 days. Median duration from referral to HCV specialist visit was 71 days. Thirty two percent of 215 patients who were referred did not have a documented specialist visit. Only twenty six patients (11%) were started on HCV treatment and the median duration from referral to initiation of treatment was 226 days. Primary care providers or HCV specialists' reasons for no referral and no HCV treatment, respectively, included patient preference, substance abuse, psychiatric disorders, lost to follow-up and others. Patient characteristics associated with an earlier assessment of Hepatitis C included marital status, HIV co-infection and history of any medical co-morbidity.

Conclusion: Most HCV- infected patients were referred to a HCV specialist. However, HCV treatment was infrequent with a prolonged duration from time of diagnosis to treatment. Patient, physician and system factors need to be addressed to improve care.

Background: Hepatitis C virus (HCV)-related liver disease has emerged as a leading cause of morbidity and mortality in HIV patients (pts). HCV therapy (HCV-RX) may reduce progression of liver fibrosis and liver related death in these pts.

Methods: Northwestern University Viral Hepatitis Registry (NU-VHR) and HIV Outpatient Study (N-HOPS) are prospective observational cohorts of ambulatory HIV pts recruited from our outpatient HIV Center.  We queried both databases for pts with chronic HCV infection (≥ 1 detectable HCV RNA) in order to define the epidemiology of HCV infection in our center and determine barriers to HCV-RX. 

Results: We identified 102 pts with chronic HCV, 90% had genotype 1. The median age was 52 years. 44 pts (43%) received HCV-RX, 18 (41%) achieved sustained virologic response.  Demographic and clinical characteristics are described in Table 1. Barriers to HCV-RX of untreated pts are listed in Table 2.

Conclusion: In this urban HIV-HCV co-infection cohort, only 43% of HIV-HCV infected pts have received HCV-RX, and 82% have ongoing infection. The major barriers to HCV-RX were poor adherence with hepatology evaluation and low uptake of therapy for patients that are eligible for treatment. Infectious Disease centered HCV-TX might provide better opportunities for treatment.
