Exploring and understanding HCV patient journeys- HEPCARE Europe project

Abstract

Background

Hepatitis C Virus (HCV) is a leading cause for chronic liver diseases worldwide. The European Union and World Health Organization aspire to eliminate HCV by 2030. However, among at-risk populations, including, homeless people, prisoners and People Who Inject Drugs, access to diagnosis and treatment is challenging. Hepcare Europe is an integrated model of care developed to address this by assessing potential reasons for these restrictions and determining measures needed to improve HCV diagnosis, treatment and access to care within different communities.

Objectives

HepCare Europe is an EU-supported project involving collaboration between five institutions in: Ireland, United Kingdom, Spain and Romania. We aim to explore the journey of care experienced by those living with HCV with a focus on previous care disruptions (loss to follow up) and the new HepCare Europe Programme.

Methods

Research teams conducted semi-structured interviews with patients who accessed services through HepCare Europe thus, patients were recruited by purposeful sampling. Patients interviewed had received, or were in the final weeks of receiving, treatment. The interviews were audio recorded, transcribed and translated into English, and sent to the Dublin team for inductive thematic analysis. Researchers from the HepCare Europe research team coded the data separately, then together.

Results

Common themes are introduced to present similarities, following individual site themes to highlight the importance of tailored interventions for each country. Key themes are: 1) Hepatitis C patients lost to follow up 2) HepCare improved access to treatment and 3) the need for improved HCV education. Individual themes also emerged for each site. These are: Ireland: New opportunities associated with achieving Sustained Virologic Responses (SVR). Romania: HCV is comparatively less crucial in light of Human Immunodeficiency Viruses (HIV) coinfections. UK: Patients desire support to overcome social barriers and Spain: Improved awareness of HCV, treatment and alcohol use.

Conclusion

This study identified how the tailored HepCare interventions enabled improved HCV testing and linkage to care outcomes for these patients. Tailored interventions that targeted the needs of patients, increased the acceptability and success of treatment by patients. HepCare demonstrated the need for flexibility in treatment delivery, and provided additional supports to keep patients engaged and educated on new treatment therapies.

Background

Hepatitis C Virus (HCV) is a major cause of liver disease worldwide [1]. It is estimated that 71 million people are chronically infected with the HCV virus [2] with approximately 5.6 million within the European Union (EU). The long-term consequence of HCV infection is severe, as chronic infections are associated with liver cirrhosis and hepatocellular carcinoma [3]. The World Health Organisation’s (WHO) global health strategy on viral hepatitis is determined to eliminate viral hepatitis as a global health threat by 2030 [4].

People who inject drugs (PWID) and people with a history of injecting drug use are highly equated with HCV infection in Europe and are a cohort associated with new infections of the virus, with estimates indicating that 1.2 million PWID in Europe have been HCV infected [5]. Additionally, members of the prison population and homeless people require additional care in the EU. It is estimated that approximately half of all prison members have a history of illicit drug use [6], while studies have shown that the highest absolute rate of disease in homeless individuals is for hepatitis C [7, 8]. To achieve HCV elimination, it is essential to acknowledge the most vulnerable populations, including prisoners, homeless persons and PWIDs for both research and clinical care. Reaching these populations requires new strategies, including simplifying the cascade of care and involving partnerships with HCV specialists and community healthcare providers [9, 10].

A recent study notes that HepCare Europe, an integrated model of care, improved access to treatment by targeting vulnerable populations and linking them to care. The study reports that, a major outcome of this model of care was that a total of 2608 participants were recruited across 218 sites in four European cities. HCV antibody test results were obtained for 2568 (98.5%); 1074 (41.8%) were antibody-positive, 687 (60.5%) tested positive for HCV-RNA, 650(60.5%) were linked to care, and 319 (43.5%) began treatment. 196 (61.4%) of treatment initiates achieved a Sustained Viral Response (SVR) at dataset closure,108 (33.9%) were still on treatment, eight (2.7%) defaulted from treatment, and seven (2.6%) had virologic failure or died [11].

While a plethora of both quantitative and qualitative literature exists on pre-Direct Acting Antiviral (DAA) HCV treatment, there is sparse literature for this new era of HCV treatment. Recent developments in treatment offer cure rates > 90%. However, the potential of these treatments will only be realised if HCV identification among PWID with linkage to treatment is optimised and therefore requires research investigating new interventions [9]. DAA’s are less invasive, present less risks to one’s health, and are less costly and more effective than previous interferon treatment. Despite this, the fear of interferon treatments remains amongst patients due to a lack of awareness of new therapies [12,13,14], presenting an additional hurdle to the list of well-documents barriers to engaging vulnerable populations in HCV care [12, 15]. In light of new advancements in medication but also in screening and assessment, new initiatives accommodating complex lifestyles have become possible including increased nurse and peer support [12, 13, 16,17,18,19]. However, many of these studies come from the UK and currently there are no studies that engage multiple cohorts across Europe.

HepCare Europe is an EU funded project with sites in four countries: Ireland, UK, Romania and Spain. The project aims to develop, implement and evaluate interventions to improve HCV diagnosis, evaluation and treatment among vulnerable populations. The structure of the HepCare intervention allowed for each site to tailor the testing and treatment plan to the needs of their populations, providing peer support and community and prison-based treatment where appropriate [20]. HepCare focuses on screening and identifying new and previously known HCV positive cases and linking them to care. In this study we aim to identify the reasons why this patient population are lost to follow up when seeking access to services and how to keep them engaged in care through interviews with patients who have completed treatment.

Methods

Ethics

Ethical approval was granted by the Institutional Review Boards in each of the following sites: Mater Misericordiae University Hospital (Dublin, Ireland); North-West Haydock Research Ethics Committee (London, UK); Hospital Universiario de Valme (Seville, Spain); and Victor Babes Clinical Hospital for Infectious and Tropical Diseases (Bucharest, Romania). Surveillance and supervision for the study were provided through the governance framework of the HepCare Europe Project. All methods were carried out in accordance with relevant guidelines and regulations.

Study design

This study adopted a qualitative approach to gain a thorough understanding of reasons for loss to follow-up in receiving HCV treatment. Utilizing semi-structured interviews meant the researchers could obtain a first-hand apprehension of the circumstances that hinder a patient’s access to treatment. Inductive thematic analysis was used following the development of major and minor themes during the data analysis stage. Researchers held semi-structured interviews with patients in person and ten interviews were selected for each site to ensure equal representation across the four countries. Due to voluntary participation, participants were not reimbursed.

Key areas for exploration were agreed and disseminated to each site. This allowed for sites to tailor questions to location, population and differences in intervention procedures and administration. The topics included HCV journey, barriers to treatment, addiction issues, effects of treatment, the treatment programme and peer experience.

Settings and recruitment

The study was conducted across four European countries; Ireland (Dublin, Cork), UK (London), Spain (Seville), and Romania (Bucharest). The inclusion criteria included the capacity to provide informed consent, being positive for HCV infection and having initiated treatment under the Hepcare initiative. Purposeful sampling was used to identify 10 patients from each country (n = 40) that were representative of the greater site cohort’s characteristics (see Table 1 ‘Recruitment’). Despite attempts to achieve the desired representation, it was not possible to obtain participants that matched all desired requirements because 1) patients had left the service (prison, etc), 2) patients declining invitation to interview, 3) patients were unable to be contacted or patients had not yet completed treatment (Lost to follow up). Informed consent was obtained from all participants involved in this study prior to the data collection stages.

Table 1 Recruitment

Data collection

Ten semi-structured interviews were collected in Bucharest, Romania, 10 interviews in Seville, Spain, 10 interviews in the UK and 10 interviews from Mountjoy Prison in Dublin, Ireland during the 2nd and 3rd year of the HepCare Europe Project. Conducting 10 interviews in each country meant that equal representation was secured across all four sites, which allowed for a fairer analysis of the data generated from the interviews. Interviews were audio recorded and transcribed by the researchers. They were translated at each site into English and sent to Dublin for analysis. Interviews were tailored to discuss the specific interventions used in each site. In Ireland, the intervention took place in a prison setting, therefore participants were interviewed about the acceptability of receiving HCV treatment in the prison setting. In London, participants were identified through homeless outreach services and community interventions. In Romania, patients were recruited through prisons, homeless shelters, addiction services and a hospital outpatient clinic. In Spain, people who inject drugs (PWIDs) were recruited from homeless and addiction services.

Data analysis

Two rounds of inductive thematic analysis were conducted the first round was conducted by the fourth author and the second round was conducted by the second and third author. A small set of pre-defined codes were used in conjunction with emerging codes. Researchers coded the interviews separately and then together, grouping codes into categories and classifying them into the identified themes. See Table 2 for ‘Example of Analysis Process’. As the interventions at each site were similar but not identical, interviews were analysed together by site. After identifying the themes from each site, the site results were then compared and the overarching themes were identified, along with some themes that were unique to the sites. Through this process, two main themes and one minor theme were identified. The major themes: 1) Hepatitis C patients had been lost to follow up 2) HepCare improved access to treatment, and the minor theme: 3) The need for widespread improved HCV education (public, patients, prisoners, and health care providers). See Table 3 for ‘Theme Progression’. Additional themes identified from individual sites are as follows: Ireland: Achieving Sustained Virologic Responses (SVR) associated with new opportunities, Romania: HCV comparatively less important in light of Human Immunodeficiency Viruses (HIV) coinfections, UK: Patients want support to address social barriers, and Spain: Increased awareness of HCV, HCV treatment and alcohol use.

Results

The first part of this section addresses common themes between all four countries enabling a clear insight into shared obstacles around Hepatitis C treatment and linkage to care. Following on from this, site-specific themes are then discussed to underpin the importance of implementing tailored interventions to meet community demands within all four countries.

Common themes

Hepatitis C patients lost to follow up

While reasons for patients lost to follow up was not homogenous between the sites, there were similar threads as to why patients were not linked to care. In this section participants share their perceptions, by firstly indicating that stigma remains a barrier, particularly with PWIDs, for accessing treatment. Patients with a history of drug injection, feel stigmatised when they are judged for their past and are solely labelled as drug users [21]. Patients also identified concerns about treatment, difficulty accessing appointments and competing priorities as additional barriers to treatment. Interviews highlighted different underlying components between sites, reiterating the need for site-specific tailored interventions. In Ireland, patient mobility was often pressurized by homelessness, the cycle of addiction and disadvantaged backgrounds. Many patients referred to traumatic family events as a catalyst for returning to a cycle of drug abuse resulting in their reluctancy to access care:

“And that brought back memories because I lost me ma and da and me other brother. Me brother was found above Christchurch OD’ed as well, you know, so it just brought back memories, and I drifted back down, and I start taking crack as I was selling gear, and then I start selling crack at night, only getting half an hours sleep for months, and I got caught up with all the shit and I got locked up you know. This [prison] saved me if I’m being honest. So now, now my mind is set not to go back there.”

“yeah, they asked me about it [treatment] once or twice but I was, to be honest with you doctor, my life was chaotic, I couldn’t manage it, do you know what I mean?”

In Romania, most patients were ineligible for treatment at the time of diagnosis, noting that they were not advanced enough to be referred for treatment and were advised to come back when their HCV condition had worsened:

“Even if I asked for it [treatment] each time I had the occasion, I never received it. I insisted on receiving the treatment when I heard about DAA treatment for the first time … I really wanted to cure my HCV and I came to the hospital more times to talk to my doctor about it. But she explained me that she can’t help me because unfortunately the treatment wasn’t available for everyone in Romania. Only patients with advanced liver fibrosis could benefit of it.”

In the UK, patients were diagnosed and informed of the need for treatment but are not assisted in obtaining specialist referrals or further appointments. With competing priorities and complex lifestyles, patient noted the need for assistance in being linked to care:

“They just told me I had it and had to go to the doctor's and I never chased that up do you know what I mean?”

Similarly, in Spain many patients were not offered treatment following their diagnosis, with some forgetting their diagnosis until the HepCare program retested them and linked them to care:

“Somebody told me the virus was sleeping so I forgot until you came to our centre.”

HepCare improved access to treatment

HepCare Europe used a variety of interventions across the four sites to ensure access to HCV testing and retention in HCV care. In Ireland, providing access to treatment in the prison system was key to engaging and retaining patients in treatment. The patients identified prison as not only an acceptable setting, but also as an ideal setting in which to receive treatment, as the structure of life in prison provides stability, helps with adherence to treatment and is associated with improved physical and mental health:

“It’s just, you’re on top of it in here [prison], where outside your doing other things, you mightn’t have time to go to hospital, do you know what I mean?.... I know that seems silly but that’s the way it is when you’re on drugs and all, do you know what I mean?... You haven’t time to be going to the hospital.”

“[about receiving treatment in the prison] yeah, because when you are outside like, you know, people have things to get down on, especially if you are taking drugs then you kinda forget what you’re doing, so being in here and getting in here, it’s a lot better because sort of follow a, you’re not going around taking drugs and the next day forgetting to take your medications.”

Patients in Romania asserted personal responsibility for their HCV treatment, with many stating that they were motivated and wanted treatment. They noted that the HepCare Europe programme helped them to access treatment far faster than they would have, if left to secure it themselves. Patients noted that HepCare removed some of the barriers to treatment, such as securing appointments with specialists and helped them remember appointments:

“But for the Project [HepCare], the treatment would have been delayed for sure. Probably I should have waited a few more years till somebody would have thought about me, would have remembered that I am also HCV positive and would have initiated treatment.”

“Due to enrolment in HepCare Project I could benefit of these investigations and finally initiated the treatment. Without this program, probably I would have got treatment but much later, at an advanced liver disease stage and with a higher risk of complications.”

In the UK, HepCare vouchers were an important incentive for engaging patients and keeping them linked to care. Many patients mentioned that the vouchers for bus fares and for meals were particularly helpful in improving attendance and keeping patients involved in the treatment process:

“You know what made me go in that van? You wanna know the truth … because I was getting a bag of crisps and a bar of chocolate free … They saved my life. All for a bar of chocolate and crisps.”

Nine out of ten patients in Spain felt that HepCare made accessing treatment easier through testing and making patients aware of their infection, improving access to services and decreasing the waiting times for appointments:

“In only three months I started treatment and with the waiting lists in Spain, I’m sure I would have had to wait longer [without HepCare].”

HepCare was also crucial in helping patients stay on treatment through reminders for appointments. These interventions combined with their personal motivation were key to achieving SVR:

“It [HepCare] has been very helpful to us. They arranged the appointments and reminded me when I had to go to the specialist service.”

Need improved HCV education

Underlying the main themes, was the steady mention of both misinformation and outdated information on HCV effects, treatment and transmission; all of which contribute to stigma (judgement) when being treated for HCV, transmission and fear. Patients identified a widespread need for education, identifying that they themselves, the public and healthcare providers would benefit:

“That’s the whole reason why I’m doing the interview- to help some other people. ‘Hey, this isn’t as bad as what people make it out to be’ and encourage them to change their life around, just need the right tools.”

In Ireland, the prisoners discussed stigma towards those who have HCV and those with a history of injected drug use who need treatment, as a result of a lack of education:

“It’s [stigma] just like, I suppose, ‘don’t be around him’, ‘you’d catch something off him’, you know. ‘He’s dirty’, you know, that kind of way.”

“There should be more education in the prisons about it [HCV], for people who don’t need it, you know what I mean; because there is a stigma to it, you know what I mean. There’s a stigma to someone on gear, but there is a bigger stigma to someone on gear that used needles.”

Additionally, patients still associate the dangers and difficulties of interferon treatment and liver biopsies with HCV treatment, despite the arrival of new, less invasive DAA therapies:

“So, she died of hepatitis, doctor. She went in to get her spleen, she got her spleen took out, and she was drinking at this point, and they told her that the way her liver has gone so far now, you have 6 months to live, we give you 6 months... And they says if you do this treatment, if must have been the interferon— It reacted wrong on her body. The next day after taking it she swelled out. She died within two or three days; you know. so that was always in my mind, you know.”

In some instances, patients were not aware that there was any treatment available for HCV at all:

“Like I said, mate I didn’t know there was like this treatment until I was in … . … . In rehab. Before that I didn’t know you could get treatment to get rid of it.”

“At the hospital they confirmed me that I am HCV positive and gave me treatment for HIV. Only recently when I was enrolled in HepCare program I was told about HCV treatment.”

In Romania, many people had been previously told or were aware of the strict treatment criteria, which required advanced disease in order to receive treatment. HepCare made patients aware that the eligibility requirements for treatment had changed allowing them to avail of treatment and linking them to care.

When receiving treatment, patients who are part of the HepCare Europe programme are educated on HCV and transmission risks to allow them to feel engaged in their treatment process and to take better precautions going forward. Despite this, the interviews indicated that there are some areas that need extra attention, such as providing a service that accommodates various literacy levels. Patients in the UK highlighted the need for staff to slow down and take more time with patients to help them understand HCV risk factors and effects:

“Simplifying terms because a lot of people there can't read and write. So will you show the diagrams cos they weren't, for example, because they see the diagrams right here right now of the liver is already and everything the red level of whatever love of blah, blah, blah is proper healthy, this one yeah. Cos I might not be able to read the, the bullet points on the left-hand side. ‘that grey area that is scarring’ and that, next picture and all that grey it is cirrhosis, sort of explain it like that.”

There was also confusion about the risk of reinfection:

“We can’t get it [HCV] though. If we get reinfected, we can’t get it [HCV] again.”

From this, patients suggest the need for HCV education along the entire cascade of care to offer correct knowledge about HCV and the risks of re-infection.

Site specific findings

IRELAND: achieving SVR is associated with new opportunities

Once they achieved SVR, patients expressed resolve and motivation to stay drug-free and to not place themselves at risk of reinfection. While Ireland was not the only site that alluded to this, it was far more pronounced in Ireland, potentially because achieving SVR was discussed in light of leaving incarceration. Patients expressed positivity and excitement for new opportunities on release, with many patients securing future plans:

“When I’m going to leave the prison now, when I do that, when I done that course of tablets, it was like getting the second chance in life to me, you know what I mean. So, when I am leaving prison now, I am going to a place called [Drug treatment service] for two years. I’m going there when I leave prison, and then I am going over to Norway. When I complete [Drug treatment service] I can volunteer in another [Drug treatment service] in Norway, so that’s my plan, doctor. You know what I mean.”

ROMANIA: HCV is comparatively less important in light of HIV Coinfections

With 8 out of 10 interviewees coinfected with HIV, an HIV diagnosis was often the stimulus for attending hospital and taking medication regularly. For many previously diagnosed with HCV, no further action to address their HCV infection was taken until after an HIV diagnosis, which was attributed both to unavailability of HCV treatment and a lack of HCV symptoms resulting in a lack of urgency:

“I was, but I didn’t care too much about it … I didn’t attend the medical appointments till 2012 I guess, when I was diagnosed with HIV.”

UK: patients require support to conquer personal and social barriers

Many patients expressed a desire for treatment and a need for support in addressing HCV and associated problems in their lives that stop them from accessing treatment. Patients want support in getting off of methadone treatment, with many noting that “you are not fully clean” until you get off of OST. Patients admitted to missing appointments, being impatient at times and having difficulty focusing on directions and remembering instructions yet asked that the staff not give up on them and help them work through these issues:

“Yeah, I missed 3 appointments and it was my own fault for that so I missed 3 appointments with her Jenny, that was her name, it was just the welfare, so she said that she can't give me another appointment. But I really need her to give me another appointment [long pause] because when you get stuck in a rut, you get stuck in a rut.”

“don't give up on people, and that's the main thing.”

SPAIN: increased awareness of HCV, treatment and alcohol use

Patients identified that they were happy to have increased awareness of HCV treatment and transmission methods, as well as a better understanding of the effects of alcohol use. While patients may have been previously diagnosed, many did not understand that they were still infected, and were happy to be retested and then treated:

“The program has made me aware of the two problems I had in my life: hepatitis c and alcohol.”

Discussion

This study confirmed many well documented barriers to treatment, as well as demonstrating how innovative and flexible interventions have the ability to improve patient engagement and retention in care.

HepCare Europe interventions address barriers to treatment

The barriers to HCV testing and treatment for People Who Inject Drugs (PWID) are well documented in literature [15, 16, 18, 19, 22]. This study confirmed many of the identified barriers vulnerable populations face when accessing HCV treatment including stigma, concerns about interferon treatment, competing priorities, mistrust between healthcare providers and PWID, and difficulty accessing and navigating the treatment pathway. This study, however, is in the unique position to understand how these barriers compare and contrast across European countries with different populations, allowing for a better understanding of the acceptability of the tailored interventions.

Need improved HCV education

Across all sites, the need for improved and widespread education on HCV was evident. Not only in order to combat stigma and decrease transmission rates, but also to engage patients in treatment. Similar to recent studies [12, 23], patients in HepCare Europe also expressed a lack of knowledge and scepticism of the new DAA therapy, viewing it as risky or uncertain. HepCare patients echoed fears of interferon treatments, recalling ‘horror stories’ of friends and family, with interviews demonstrating a continued misunderstanding of HCV, with patients confused about transmission, reinfection and new treatment options. Many patients discussed their own misunderstandings as a driving force to want to engage in peer support work themselves, wanting to let others know about the improved DAA therapy and opportunities that come with it.

Comparison with other literature

Current literature notes that competing priorities and the deprioritization of HCV discourage patient engagement [12, 24]. As was suggested previously [17, 22], setting services within the prison system is essential for engagement and adherence with the Irish cohort. Patients identified that they would be unlikely to complete treatment outside of prison services and found prison to be an ideal setting to receive treatment due to their improved mental health and stability.

In the UK cohort, patients expressed the need for assistance in being linked to care, specifically with making specialist appointments. HepCare patients noted that they received no support in making appointments for treatment after diagnosis, reiterated findings from Rhodes et al. [23] that patients in London are not empowered to demand or access treatment.

In Romania, 8 out of 10 patients interviewed were coinfected with HIV. Rhodes et al. has attributed co-infection to the deprioritization of HCV [23] and could also explain why Romanian patients did not highlight stigma as an issue as is suggested in other studies [13]. Coupled with coinfection, many Romanian patients were previously turned away from treatment as they failed to meet eligibility criteria.

In Romania, DAA therapy was only available for patients with advanced liver fibrosis (Metavir F3 and F4 score) until 2018 [20], which was understood and reiterated by the patients.

Judgement from healthcare providers, both surrounding HCV and their injecting drug use, led to patients delaying treatment in both Romania and the UK. Treloar et al. [16] suggests that judgement contributes to patients not considering themselves as legitimate patients. HepCare confirmed that the use of peer workers and the relationships between healthcare providers and patients is crucial for the uptake of services and adherence to treatment [12].

HepCare Europe demonstrated a model for improved HCV testing and linkage to care for vulnerable populations. The use of innovative interventions to engage patients, presenting testing and treatment opportunities outside of hospitals in areas that the patients felt more comfortable has proven acceptable to patients.

Strengths and limitations

This is the first multi-country qualitative research study on DAA therapy interventions. The study was unable to achieve the desired recruitment criteria in some cohorts due to factors beyond control, such as: patients left treatment (prison), patients unwilling to participate, or patients not having completed treatment yet. The addition of focus groups with healthcare providers could provide useful additional information on the issues encountered with these interventions.

Implications for practice, policy and future research

This study demonstrates the ability of targeted interventions to improve the identification, evaluation and treatment of HCV in vulnerable populations. Through a unique system of care involving support in linkage to care and intensified peer support, HepCare Europe demonstrates the importance of investing in personalized medical care for vulnerable populations. The ability of HepCare to not only enrol patients, but to keep them engaged in care, demonstrates the need for services to be moved out of the hospital and into the communities of these populations, where they face less stigma and can be incentivized to present for testing and treatment.

Conclusions

This is the first multi-country qualitative study on perceptions of DAA therapy. The unique cohort allows us to compare and contrast treatment modalities and acceptability across Europe, identifying common themes and highlighting areas for customization. Patients in all sites found HepCare to improve their HCV treatment experience through decreased waiting times, assistance navigating the care pathway and providing services in non-traditional locations which patients found more suitable to their complex lifestyles. HepCare Europe represents a best-practice example for treatment delivery with site specific modifications in key populations.
