Re-evaluation of chronic hepatitis B and hepatitis C patients lost to follow-up: results of the Northern Holland hepatitis retrieval project

Enhancing linkage to care for hepatitis B, D, and C patients: A retrospective-prospective study

BACKGROUND

The WHO has set a goal to decrease viral hepatitis-related fatalities by 65% by 2030.

AIMS

To locate and retrieve to care all individuals diagnosed with hepatitis B, D or C, and investigate why they were not linked to appropriate medical management.

METHODS

We conducted a retrospective-prospective search for patients with hepatitis B, D or C virus (HBV, HDV and HCV) infection in the central laboratory database of the Barcelona northern health area (catchment population, 450,000). We reviewed records and contacted candidates for retrieval who were offered a specialist medical visit.

RESULTS

We reviewed records of 3731 patients with viral hepatitis (January 2019-December 2022): 1763 HBsAg+, 69 anti-HDV+ and 1899 HCV-RNA+. Among these, 644 (37%) HBV, 20 (29%) HDV and 1116 (56%) HCV patients were not currently linked to care. The proportion of patients receiving appropriate care was higher in HBV and HDV (p < 0.0001), and a higher percentage of unlinked hepatitis C patients had low life expectancy/comorbidities (39%; p < 0.0001). After implementing the linkage strategy, 254 HBV, 16 HDV and 54 HCV patients were successfully reintegrated into care. Among 1780 patients requiring linkage, 638 (35.8%) had moved to another health area or were missing essential contact data.

CONCLUSIONS

Among patients with viral hepatitis who required appropriate specialist care and were eligible for contact, 64% with HBV, 100% with HDV and 27% with HCV were successfully reintegrated into care. Overall, 324 (47.2%) eligible patients were linked to care, indicating the success of this strategy.

Tackling a worrisome rate of lost to follow-up among migrants with hepatitis B in French Guiana

OBJECTIVES

Management of Hepatitis B virus (HBV)-infected patients, whether they are receiving treatment or not, necessitates long-term follow-up. This study evaluated the rate of lost to follow-up (LTFU) among HBV-infected patients and the feasibility of a callback strategy to re-engage these patients in HBV care.

PATIENTS AND METHODS

We conducted a retrospective study involving HBV-infected patients attending the outpatient clinic at Cayenne Hospital, French Guiana. LTFU was defined as patients who had not attended the clinic for more than 18 months. A callback strategy was implemented to re-engage LTFU patients in HBV care.

RESULTS

Between 1st January 2015 and 31st December 2018, 203 HBV-infected patients were referred to the outpatient clinic; 95/203 (46.8 %) were LTFU, resulting in a crude LTFU rate of 2.6 (95 % CI, 2.1-3.2) per 100 person-years. At baseline, patients aged 30-40 years (aOR, 0.48; 95 %CI, 0.24-0.95) and those who initiated treatment (aOR, 0.26; 95 %CI, 0.10-0.60) were less likely to be LTFU. Through application of the callback strategy, 55/95 (58 %) patients were successfully contacted, and 46/55 (84 %) attended the outpatient clinic for a liver assessment. The EASL criteria for treatment eligibility were met by 3/46 (4 %) patients. Compared to non-LTFU patients, LTFU patients were more likely to be in informal employment (p = 0.03) and to be receiving state medical assistance (p < 0.01), and had lower levels of knowledge about their condition (p < 0.01).

CONCLUSIONS

The callback strategy to re-engage LTFU patients in HBV care is feasible and effectively identifies those eligible for antiviral therapy.

Results from a retrospective case finding and re-engagement exercise for people previously diagnosed with hepatitis C virus to increase uptake of directly acting antiviral treatment

BACKGROUND

Direct acting antivirals (DAAs) for the Hepatitis C virus (HCV) have shifted the World Health Organisation global strategic focus to the elimination of HCV by 2030. In England, the UK Health Security Agency (UKHSA) led a national 'patient re-engagement exercise', using routine surveillance data, which was delivered through the HCV Operational Delivery Networks (ODNs) with support from National Health Service England (NHSE), to help find and support people with a positive HCV PCR test result to access treatment. We report a quantitative evaluation of outcomes of this exercise.

METHODS

Individuals with a recorded positive HCV antibody or PCR result between 1996 and 2017 were identified using UKHSA's records of HCV laboratory diagnosis. Linkage with established health-care datasets helped to enhance patient identification and minimise attempts to contact deceased or previously treated individuals. From September to November 2018 each ODN was provided with a local list of diagnosed individuals. ODNs were asked to perform further data quality checks through local systems and then write to each individual's GP to inform them that the individual would be contacted by the ODN to offer confirmatory HCV PCR testing, assessment and treatment unless the GP advised otherwise. Outcomes of interest were receipt of treatment, a negative PCR result, and death. Data were collected in 2022.

RESULTS

Of 176,555 individuals with a positive HCV laboratory report, 55,329 individuals were included in the exercise following linkage to healthcare datasets and data reconciliation. Participants in the study had a median age of 51 years (IQR: 43, 59), 36,779 (66.5%) were males, 47,668 (86.2%) were diagnosed before 2016 and 11,148 (20.2%) lived in London. Of the study population, 7,442 (13.4%) had evidence of treatment after the re-engagement exercise commenced, 6,435 (11.6%) were reported as PCR negative (96% had no previous treatment records), 4,195 (7.6%) had prescription data indicating treatment before the exercise commenced or were reported to have been treated previously by their ODN, and 2,990 (5.4%) had died. The status of 32,802 (59.3%) people remains unknown.

CONCLUSIONS

A substantial number of those included had treatment recorded after the exercise commenced, however, many more remain unengaged. Evaluation of the exercise highlighted areas that could be streamlined to improve future exercises.

The Application of Australian Rights Protections to the Use of Hepatitis C Notification Data to Engage People 'Lost to Follow Up'

Hepatitis C is a global public health threat, affecting 56 million people worldwide. The World Health Organization has committed to eliminating hepatitis C by 2030. Although new treatments have revolutionised the treatment and care of people with hepatitis C, treatment uptake has slowed in recent years, drawing attention to the need for innovative approaches to reach elimination targets. One approach involves using existing notifiable disease data to contact people previously diagnosed with hepatitis C. Within these disease surveillance systems, however, competing tensions exist, including protecting individual rights to privacy and autonomy, and broader public health goals. We explore these issues using hepatitis C and Australia's legislative and regulatory frameworks as a case study. We examine emerging uses of notification data to contact people not yet treated, and describe some of the ethical dilemmas associated with the use and non-use of this data and the protections that exist to preserve individual rights and public health. We reveal weaknesses in rights protections and processes under Australian public health and human rights legislation and argue for consultation with and involvement of affected communities in policy and intervention design before notification data is used to increase hepatitis C treatment coverage.

The Impact of Living With Chronic Hepatitis B on Quality of Life: Implications for Clinical Management

Living with chronic hepatitis B (CHB) has physical, social, and emotional impacts that often negatively affect patients' quality of life. These impacts are not usually captured during routine care. This article presents information on the impact of living with CHB and the importance of integrating health-related quality-of-life assessment into CHB care. Using a global online survey, people ages ≥18 living with CHB were asked about physical, social, and worry impacts. Of 1707 respondents, most were male (67%), < 45 years of age (81%); and 52% identified as Black. Of all participants, 66% reported physical impact, 55% reported social impact, and 49% reported worry impact of living with CHB. Those from Africa and the Western Pacific were most likely to report physical impact. Younger participants (18-45) and those not on treatment were significantly more likely to report physical and social impact. People living with CHB are impacted physically, socially, and emotionally, varied by demographic factors and disease experience. These impacts should be captured and addressed as part of routine CHB care.

Retrieval of HCV patients lost to follow-up as a strategy for Hepatitis C Microelimination: results of a Brazilian multicentre study

BACKGROUND

Several HCV patients in Brazil were lost to follow-up (LTFU) in the last two decades before achievement of sustained virological response (SVR). Strategies to recall those diagnosed but untreated patients have been used elsewhere with different success rates.

AIM

To identify and retrieve LTFU patients in order to offer them the treatment with the current highly effective direct acting antiviral agents (DAAs).

METHODS

Registries ofall HCV patients from three large reference centers in Brazil were retrospectively reviewed to identify those with no registry of SVR. Reasons for non-achievement of SVR were elicited in HCV-RNA + patients. All patients who were not treated or cured were contacted to offer the therapy with DAAs.

RESULTS

10,289 HCV patients (50% males, mean age 52 ± 11 years) were identified. Only 4,293 (41.7%) had been successfully treated previously. From the remaining 5,996 most were LTFU (59%), were not treated for other reasons (14.7%) or were non-responders (26.3%). After revision of the charts 3,559 were considered eligible to be retrieved. The callback success of phone calls was 18%, 13% to cellphone messages (SMS or WhatsApp) and 7% to regular mail. Five-hundred sixty patients had been already treatedor were on treatment and 234 were reported to be dead or transplanted. Finally, 201 had made an appointment and initiated antiviral treatment.

CONCLUSION

Even considering the low callback rate, retrieval of LTFU patients was shown to be an important strategy forhepatitis C micro-elimination in Brazil.

Hepatitis C micro-elimination through the retrieval strategy of patients lost to follow-up

BACKGROUND AND AIM

World Health Organization sets up an ambitious and attainable goal to eliminate hepatitis C (HCV) by 2030. The previous diagnosed HCV patients lost to follow-up were considered as an important target group for HCV elimination. We conducted a call back program to retrieve the lost to follow-up HCV patients and link them to care in our hospital. By analyzing and comparing our result with that from other studies, we wish to improve our retrieval strategy and provide our experience to the general communities.

METHODS

A list of the patients with a medical record showing seropositive for antibody to HCV (anti-HCV Ab) from 2004 to 2017 was retrieved by the department of intelligent technology of our hospital. Three dedicated staff members reviewed the patients' electronic medical records (EMRs) and recruited the patient lost follow-up to the call back program. The staff members contacted the qualified patients by telephone and inquired about their opinions for treating their chronic HCV infection. We also informed the patients about the retrieval strategy and why we contact them. As our National Health Insurance request, we gave all patient one informed consent for hepatitis C treatment. Informed consents have been obtained from all patients. Referrals to our gastroenterology unit (GU) were arranged for the patients who would like to continue their chronic HCV care in our hospital.

RESULTS

There were 31,275 anti-HCV positive patients. We included 11,934 patients (38.2%) into the call back system and contacted them by telephone. Based on the response to our call, we ascertained 1277 eligible cases (10.7%) for retrieval. The patients who were younger (< 55), lived in Taoyaun City or had tested positive for anti-HCV Ab at the department of internal medicine department had an increased rate of successful call back. There were 563 patients (44.1%) returning to our GU. Of them, 354 patients (62.9%) were positive for HCV viremia. 323 patients (91.2%) received the DAAs treatment. The SVR12 with Grazoprevir + elbasvir, Glecaprevir + pibrentasvir, Sofosbuvir + ledipasvir and Sofosbuvir + velpatasvir were 97.9%, 98.8%, 100% and 97.5%, respectively.

CONCLUSIONS

Call back system can expand our reach to those unaware or ignoring chronic HCV infection patients and link them to treatment.

Recommendations for the integral diagnosis of chronic viral hepatitis in a single analytical extraction

The Spanish Society of Digestive Pathology (SEPD), the Spanish Association for the Study of the Liver (AEEH), the Spanish Society of Infections and Clinical Microbiology (SEIMC) and its Viral Hepatitis Study Group (GEHEP), and with the endorsement of the Alliance for the Elimination of Viral Hepatitis in Spain (AEHVE), have agreed on a document to carry out a comprehensive diagnosis of viral hepatitis (B, C and D), from a single blood sample; that is, a comprehensive diagnosis, in the hospital and/or at the point of care of the patient. We propose an algorithm, so that the positive result in a viral hepatitis serology (B, C and D), as well as human immunodeficiency virus (HIV), would trigger the analysis of the rest of the virus, including the viral load when necessary, in the same blood draw. In addition, we make two additional recommendations. First, the need to rule out a previous hepatitis A virus (VHA) infection, to proceed with its vaccination in cases where IgG-type studies against this virus are negative and the vaccine is indicated. Second, the determination of the HIV serology. Finally, in case of a positive result for any of the viruses analyzed, there must be an automated alerts and initiate epidemiological monitoring.

Implementation of a re-linkage to care strategy in patients with chronic hepatitis C who were lost to follow-up in Latin America

To achieve WHO's goal of eliminating hepatitis C virus (HCV), innovative strategies must be designed to diagnose and treat more patients. Therefore, we aimed to describe an implementation strategy to identify patients with HCV who were lost to follow-up (LTFU) and offer them re-linkage to HCV care. We conducted an implementation study utilizing a strategy to contact patients with HCV who were not under regular follow-up in 13 countries from Latin America. Patients with HCV were identified by the international classification of diseases (ICD-9/10) or equivalent. Medical records were then reviewed to confirm the diagnosis of chronic HCV infection defined by anti-HCV+ and detectable HCV-RNA. Identified patients who were not under follow-up by a liver specialist were contacted by telephone or email, and offered a medical reevaluation. A total of 10,364 patients were classified to have HCV. After reviewing their medical charts, 1349 (13%) had undetectable HCV-RNA or were wrongly coded. Overall, 9015 (86.9%) individuals were identified with chronic HCV infection. A total of 5096 (56.5%) patients were under routine HCV care and 3919 (43.5%) had been LTFU. We were able to contact 1617 (41.3%) of the 3919 patients who were LTFU at the primary medical institution, of which 427 (26.4%) were cured at a different institutions or were dead. Of the remaining patients, 906 (76.1%) were candidates for retrieval. In our cohort, about one out of four patients with chronic HCV who were LTFU were candidates to receive treatment. This strategy has the potential to be effective, accessible and significantly impacts on the HCV care cascade.

Hepatitis C Elimination in the Netherlands (CELINE): How nationwide retrieval of lost to follow-up hepatitis C patients contributes to micro-elimination

BACKGROUND & AIMS

The number of chronic hepatitis C virus (HCV)-infected patients who have been lost to follow-up (LTFU) is high and threatens HCV elimination. Micro-elimination focusing on the LTFU population is a promising strategy for low-endemic countries like the Netherlands (HCV prevalence 0.16%). We therefore initiated a nationwide retrieval project in the Netherlands targeting LTFU HCV patients.

METHODS

LTFU HCV-infected patients were identified using laboratory and patient records. Subsequently, the Municipal Personal Records database was queried to identify individuals eligible for retrieval, defined as being alive and with a known address in the Netherlands. These individuals were invited for re-evaluation. The primary endpoint was the number of patients successfully re-linked to care.

RESULTS

Retrieval was implemented in 45 sites in the Netherlands. Of 20,183 ever-diagnosed patients, 13,198 (65%) were known to be cured or still in care and 1,537 (8%) were LTFU and eligible for retrieval. Contact was established with 888/1,537 (58%) invited individuals; 369 (24%) had received prior successful treatment elsewhere, 131 (9%) refused re-evaluation and 251 (16%) were referred for re-evaluation. Finally, 219 (14%) were re-evaluated, of whom 172 (79%) approved additional data collection. HCV-RNA was positive in 143/172 (83%), of whom 38/143 (27%) had advanced fibrosis or cirrhosis and 123/143 (86%) commenced antiviral treatment.

CONCLUSION

Our nationwide micro-elimination strategy accurately mapped the ever-diagnosed HCV population in the Netherlands and indicates that 27% of LTFU HCV-infected patients re-linked to care have advanced fibrosis or cirrhosis. This emphasizes the potential value of systematic retrieval for HCV elimination.

Impact of an Accelerated Pretreatment Evaluation on Linkage-to-Care for Hepatitis C-infected Persons Who Inject Drugs

Background:

Historically, hepatitis C virus (HCV) pretreatment evaluation has required multiple visits, frequently resulting in loss to follow-up and a delayed initiation of treatment. New technologies can accelerate this process. We investigated the feasibility of a single-day evaluation program and its impact on evaluation completion, treatment eligibility awareness, and treatment initiation among people who inject drugs (PWIDs).

Methods:

HCV-infected PWID who were unaware if they were eligible for treatment were recruited in a prospective evaluation of an accelerated model of care between 2017 and 2019 and compared to a historical cohort. The patients underwent a medical evaluation, rapid HCV viral load testing, and transient elastography during a single visit, at the end of which they were informed whether they were eligible for treatment. A historical cohort of patients fulfilling the same inclusion criteria and evaluated with the usual standard of care spanning several visits who were examined at the addiction medicine clinic from 2014 to 2016 served as the comparison group.

Results:

The accelerated and historical cohorts included 99 and 76 patients, respectively. The cohorts did not differ significantly by age and gender, but more patients in the historical cohort were undergoing opioid agonist therapy, while more patients in the accelerated cohort injected drugs in the last month. An accelerated evaluation resulted in a higher rate of evaluation completion (100% vs 67.1%; P < .001). Among those eligible for treatment, the proportion of those initiating treatment was similar between the groups (51/64 (79.7%) vs. 26/37 (70.3%); P = .28). The delay in the initiation of treatment was shorter in the accelerated cohort than in the historical cohort (69 (IQR: 49-106) days vs. 219 (IQR: 141-416) days; P < .001).

Conclusions:

Accelerated evaluation enhanced the awareness of eligibility and reduced the time to initiation among eligible patients.

Trial Registration:

This study is registered on www.clinicaltrials.gov (NCT02755402).

Cases of liver disease lost in the health system: a call to action

We recently reported our experience searching for patients with primary biliary cholangitis (PBC) who were lost in the health system. Our search of the databases of 4 hospitals, 3 of which were tertiary institutions, revealed that sufficient data were available to ensure a reliable diagnosis (cholestasis, positive antimitochondrial antibody titer, and no other liver disease) in 14.3% (100/697) of cases of PBC.

Retrieval and treatment of patients with primary biliary cholangitis who are lost in the health system

INTRODUCTION

hepatitis C patients loss to follow-up in the health care system has been shown to have negative consequences. This study aimed to investigate this issue as regards primary biliary cholangitis.

METHODS

the databases (immunology, biochemistry, clinical reports, drug dispensation, appointments) of 4 reference hospitals in Spain (serving a population of 1,450,000 inhabitants) were analyzed. The diagnosis of primary biliary cholangitis was based on an antimitochondrial antibody titer ≥ 1:80, chronically elevated alkaline phosphatase, and the absence of other liver disease. Patients were classified as lost in the absence of reports indicating a diagnosis, specific medical follow-up, and/or treatment with bile salts.

RESULTS

a total of 1372 patients with antimitochondrial antibody titers ≥ 1:80 were included between January 2010 and June 2019. A total of 697 (50.8 %) were classified as having primary biliary cholangitis, and 100 patients (14.3 %; 95 % CI: 11.8-17.2) were identified as lost. Of these, 30 were contacted and retrieved. The median age was 70 years, 93 % were female, median alkaline phosphatase was 185 IU/L, 10 % had pruritus, and 27 % had a transient elastography value > 9.5 kPa. The disease was confirmed and ursodeoxycholic acid was started in all 30 patients. Death was liver-related in 6 of the 100 patients classified as lost.

CONCLUSION

up to 14.3 % of patients (1 out of 7) with a definitive diagnosis of primary biliary cholangitis remain undiagnosed, thus preventing monitoring and treatment. More than a quarter are at risk of advanced liver disease and its complications. Patients lost in the system must be identified and retrieved, and searching hospital databases is a suitable approach to meet this goal.

Community screening identifies undiagnosed chronic liver disease in high-risk populations

BACKGROUND AND AIM

Liver cirrhosis is the primary risk factor for the development of hepatocellular carcinoma. Most conditions that lead to cirrhosis are treatable, or modifiable. Therefore, a community-based screening program targeting high-risk groups was designed for early diagnosis and intervention of liver disease, to offset the rising burden of hepatocellular carcinoma in Australia.

METHODS

Two nurse consultants from a tertiary liver center performed community screening of pre-identified cohorts at risk of viral hepatitis and chronic liver disease, with transient elastography and/or serology testing for chronic hepatitis B virus (HBV) and hepatitis C virus (HCV), in addition to standard blood tests. A positive screening result was defined as any of the following: liver stiffness measurement (LSM) ≥ 9.5 kPa, positive HCV RNA, or positive HBV surface antigen. Individuals who screened positive were linked to the liver center for management.

RESULTS

Nine hundred and twenty-six subjects were screened over a 6-year period, of which 122/926 (13.2%) had evidence of chronic liver disease. Chronic viral hepatitis was diagnosed in 91 participants (HBV = 23, HCV = 67, and co-infection = 1), while non-alcoholic fatty liver disease was diagnosed in 14 participants. Advanced fibrosis (LSM ≥ 9.5 kPa) was detected in 42/866 (4.9%) subjects with available LSM. Loss to follow-up occurred in 36/91 (39.6%) participants with chronic viral hepatitis.

CONCLUSIONS

Targeting high-risk populations for community screening and intervention increases early identification of chronic liver disease. This may reduce the incidence of liver cirrhosis and hepatocellular carcinoma. Loss to follow-up remains an ongoing challenge, requiring better strategies.

Patients with hepatitis C lost to follow-up: ethical-legal aspects and search results

INTRODUCTION

data on the prevalence and characteristics of hepatitis C patients lost to follow-up are lacking. In addition, the identification of this population clashes with data protection regulations.

METHODS

the identification and contact protocol was submitted to the Health Care Ethics Committee. The protocol was based on anti-HCV serology test results for 2010-2018, which were obtained from the Microbiology Department. In addition, the situation of the patients in the hospital and regional database was analyzed, based on the following classification: a) chronic hepatitis C, if the last HCV RNA determination was positive; b) cured hepatitis C, if the last HCV RNA determination was negative after 12 weeks of treatment; and c) possible hepatitis C, if anti-HCV antibodies were positive with no result for HCV RNA. Lost patients were defined as those with chronic or possible hepatitis C and no follow-up in the Digestive Diseases or Internal Medicine Departments. The patients were contacted by postal mail and then by telephone, so that they could be offered treatment.

RESULTS

the Ethics Committee considered that the protocol fulfilled the bioethical principles of autonomy, beneficence, non-maleficence and justice and that contact was ethically desirable. From 4,816 positive anti-HCV serology results, 677 patients were identified who were lost to follow-up (14.06 %; 95 % CI, 13.2-15.2). The mean age was 54 years, 61 % were male, 12 % were foreign born and 95 % were mono-infected. The study of each serology result took 1.3 minutes. One-quarter (25 %) of the losses corresponded to the Digestive Diseases and Internal Medicine Departments. Of the 677 losses, serology testing had only been ordered for 449 patients (66.3 %) and the remaining 228 (33.7 %) also had a positive HCV RNA result.

CONCLUSION

a large number of patients with hepatitis C are lost to follow-up. Searching for and contacting these patients is legally and ethically viable.

Retrieval of lost patients in the system for hepatitis C microelimination: a single-center retrospective study

Background

Hepatitis C virus (HCV) is one of the major causes of chronic liver disease, cirrhosis, and liver cancer. Most of the infected people have no clinical symptoms. The current strategy for HCV elimination includes test and treatment. In this study, we aimed to evaluate the campaign for retrieving patients who were lost to follow-up, for subsequent re-evaluation.

Methods

From January 2020 to October 2020, patients who had prior tests for positive anti-HCV antibody in 2010–2018 in our hospital were enrolled for our patient callback campaign. Patients who had unknown HCV RNA status or no documented successful antiviral therapy history were selected for anti-HCV therapy re-evaluation. To facilitate patient referral in the hospital, we developed an electronic reminding system and called the candidate patients via telephone during the study period.

Results

Through the hospital electronic system, 3783 patients with positive anti-HCV antibody documentation were identified. Among them, 1446 (38.22%) had tested negative for HCV RNA or had anti-HCV therapy, thereby excluded. Of the 2337 eligible patients, 1472 (62.99%) were successfully contacted and called back during the study period for subsequent HCV RNA testing and therapy. We found that 42.19% of the patients had positive HCV RNA and 88% received subsequent anti-HCV therapy.

Conclusions

A significant number of patients with positive HCV serology were lost for HCV confirmatory test or therapy in the hospital. Therefore, this targeted HCV callback approach in the hospital is feasible and effective in achieving microelimination.

Hepatitis C standards of care: A review of good practices since the advent of direct-acting antiviral therapy

Significant steps must be taken to reduce the global incidence and prevalence of hepatitis C virus (HCV) and mortality from HCV infection to achieve the WHO goal of eliminating viral hepatitis as a public health threat by 2030. Proper epidemiological surveillance of the full continuum of care is essential for monitoring progress and identifying gaps that need to be addressed. The tools required for elimination have largely been established, and the issue at hand is more how they should best be implemented in different settings around the world. Documenting good practices allows for knowledge exchange to prevent transmission and improve health outcomes for people with HCV. This review found 13 well documented HCV good practices that have become the standard of care or that should become the standard of care as soon as possible. In 2013, highly effective direct-acting antiviral therapy became available, which has cure rates of over 95%. Together with this new therapy, evidence-based good practices can help countries eliminate viral hepatitis C.

Impact of a Nurse Care Coordinator Supporting a Clinical Pharmacist Practitioner in Further Managing HCV-Infected Patients

Patients undergoing chronic hepatitis C treatment require monitoring to ensure that treatment is both safe and effective. However, many of these patients are lost to follow-up. The aim of this study was to investigate the impact of implementing a Nurse Care Coordinator's role in a pharmacy-based collaborative team to enhance the care of hepatitis C-infected patients. This was a 6-month retrospective chart review from July 2018 to January 2019, where 116 patients receiving hepatitis C treatment were referred to the Nurse Care Coordinator for further management. The Nurse Care Coordinator provided more than a 5-fold increase in contact method by telephone call. Of the 116 referred hepatitis C-infected patients, 44.8% (n = 52) of patients were referred due to a missed post-treatment Week 12 follow-up appointment to assess for cure. The Nurse Care Coordinator successfully rescheduled 96.2% (50/52) of follow-up appointments to assess for cure; 90% (45/50) of those patients adhered to scheduled appointment; and 97.8% (44/45) of patients had undetectable hepatitis C virus RNA, indicating cure. The primary success rate of the intended Nurse Care Coordinator arrangement was 97.4% (n = 113), where 89.4% (101/113) of patients successfully adhered to the intervention. This study demonstrates the positive impact the Nurse Care Coordinator had in successfully re-engaging previously lost to follow-up patients back into clinic.

Loss to follow-up in the hepatitis C care cascade: A substantial problem but opportunity for micro-elimination

Since the advent of direct-acting antivirals, elimination of hepatitis C viral (HCV) infections seems within reach. However, studies on the HCV cascade of care show suboptimal progression through each step for all patient groups. Loss to follow-up (LTFU) is a major issue and is a barrier to HCV elimination. This review summarizes the scale of the LTFU problem and proposes a micro-elimination approach. Retrieving LTFU patients and re-engaging them with care again has shown to be feasible in the Netherlands. Micro-elimination through retrieval can contribute to reaching the World Health Organization's viral hepatitis elimination targets by 2030.

Retrieval and re-evaluation of previously diagnosed chronic hepatitis C infections lost to medical follow-up in the Netherlands

OBJECTIVES

Many individuals previously diagnosed with chronic hepatitis C virus (HCV) infection are likely to be lost to medical follow-up and, therefore, remain untreated despite new highly effective drug treatment, direct acting antivirals. We aim to identify and retrieve these chronic HCV-infected individuals to re-evaluate them and offer treatment.

METHODS

Possible chronic HCV infections were identified from test results of the medical microbiological laboratory, notifications to the public health service, and the hospital registries over the past 15 years were checked in South Limburg, the Netherlands. Individuals were contacted based on the physician-patient relationship of the gastroenterologist or microbiologist (retrieval). Individuals were informed about the new treatment options, offered an HCV-RNA test, and if still positive, referred to the gastroenterologist for treatment (re-evaluation).

RESULTS

In total, 689 individuals with a positive anti-HCV test in the past were identified, 308 (45%) were eligible for retrieval, 90 (29%) of them were retrieved, 34 (38%) of those retrieved were re-evaluated, 19 (56%) of those tested were HCV-RNA positive, and 12 (63%) of these individuals were offered treatment.

CONCLUSION

During every step of the retrieval chain, many patients were lost. Nevertheless, with substantial effort, we were able to identify, retrieve, and positively re-evaluate a limited number of individuals with a possible chronic HCV infection who were lost to medical follow-up (19 patients). With this case-finding approach, we were able to prevent potential severe complications in these patients and contribute to a small step in the eradication of HCV in the Netherlands.

The balancing perspective of hard-to-reach hepatitis C patients who were lost to follow-up: A qualitative study

Background

In the foreseeable future, patients with hepatitis C virus (HCV) with good healthcare access will all have been cured and the lost to follow-up (LFU) HCV-population will increasingly exist of hard-to-reach patients. Efforts to retrieve these individuals with HCV have been moderately successful so far. A deeper understanding of the reasons for loss to follow-up and the underlying processes is lacking.

Aims

To explore reasons for previous loss to follow-up in patients with HCV who have been brought back into care.

Methods

In 2017, fifteen patients with HCV who were evaluated at the University Medical Center Utrecht (UMCU) Infectious diseases outpatient clinic as part of the “REtrieval And cure of Chronic Hepatitis C” (REACH)-project were included in this study through convenience sampling. Face-to-face semi-structured in-depth interviews were conducted and a qualitative analysis based on the grounded theory was applied.

Results

A basic socio- psychological process named “maintaining the achieved balance” was uncovered in patients with HCV who were LFU. This “achieved balance” is the result of a transformative process following the initial HCV diagnosis. It is a steadfast stance in which participants keep HCV out of sight and in the margin of their lives in order to reestablish an optimal state of well-being. The balancing perspective is subsequently defended by repeated evasive behavioral patterns to avoid confrontation with the disease.

Conclusion

The balancing perspective gives insight into why individuals with HCV were not retained in care but also why they remained LFU thereafter. Physicians should realize that this mindset can be persistent and repeated efforts may be needed to finally trace and retrieve these patients.

Hepatitis C elimination in the Netherlands (CELINE): study protocol for nationwide retrieval of lost to follow-up patients with chronic hepatitis C

Background

The Netherlands has a low hepatitis C virus (HCV) prevalence, estimated at 0.16%. Previous studies have shown that up to 30% of the diagnosed HCV population in the Netherlands has been lost to follow-up (LTFU). Retrieval of these patients could halt progression of liver disease in infected patients, reduce the number of infected individuals and limit HCV transmission. Several regional Dutch retrieval projects have already been executed, which demonstrated that retrieval is feasible. Therefore, we initiated a nationwide retrieval project, aiming to achieve microelimination in previously diagnosed but LTFU patients with chronic HCV through retrieval.

Methods

Laboratory records will be used to identify possible patients with chronic hepatitis C, defined as either a positive most recent HCV RNA or positive HCV antibodies without known RNA result. Reviewing patient records and obtaining current contact information from municipality databases will identify LTFU patients who are eligible for retrieval. These patients will be invited for outpatient clinic care. The primary outcome of the study is the total number of LTFU patients who have been successfully linked to care.

Discussion

Hepatitis C ELimination In the NEtherlands (CELINE) is within the remit of WHO elimination targets and the Dutch National Hepatitis Plan. The methodology of CELINE is based on previously conducted regional retrieval projects and is designed to overcome some of their limitations. After ethical approval was obtained in 2018, the first centre initiated retrieval in 2018 and the project is expected to finish in 2021.

REtrieval And cure of Chronic Hepatitis C (REACH): Results of micro-elimination in the Utrecht province

BACKGROUND

The Netherlands is one of the six European countries considered on track to eliminate hepatitis C virus by 2030. To achieve this goal, continuous efforts have to be put into designing efficient case-finding strategies, including the retrieval of previously diagnosed hepatitis C virus-infected who are lost to follow-up.

AIMS

To trace and treat all lost to follow-up hepatitis C virus patients in the Utrecht region and create an efficient retrieval strategy that can be used in future (national) retrieval initiatives.

METHODS

Positive hepatitis C virus diagnostic tests (anti-hepatitis C virus IgG or hepatitis C virus-RNA) from the laboratory of all four hospitals and one central laboratory for primary care diagnostics in the province of Utrecht from 2001 to 2015 were linked to clinical records. Untreated patients with available contact information were deemed eligible for retrieval and invited for reevaluation with (virology) blood tests, fibroscan measurement and possible direct-acting antiviral therapy.

MAIN RESULTS

After screening all hepatitis C virus diagnostics, 1913 chronic hepatitis C virus-infected were identified of which 14.1% (n = 269) were invited back into care. Overall, 17.4% was traced with the highest yield (28.3%) in those who lived in the Utrecht province. Through renewed patient assessments, 42 chronic hepatitis C virus infections were re-identified (76% with a history of intravenous drug use, 24% with Metavir F3-F4). Until now, 59% has either scheduled or initiated direct-acting antiviral therapy.

CONCLUSION

The retrieval of previously diagnosed hepatitis C virus patients through screening of laboratory diagnostics from the past is feasible and should be pursued for further control and reduction of hepatitis C virus infection. Retrieval is most successful when performed regionally.

LAY SUMMARY

To completely eliminate chronic hepatitis C virus (HCV) infection and prevent complications, undiagnosed and also previously diagnosed but lost to follow-up (LFU) HCV patients have to be brought (back) into care for therapy. Retrieval of LFU HCV patients through screening of laboratory diagnostics from the past is feasible and most successful when performed regionally.

Strategies for achieving viral hepatitis C micro-elimination in the Netherlands

The Netherlands is striving to achieve national elimination of the hepatitis C virus (HCV) as one of the first countries worldwide. The favorable HCV epidemiology with both low prevalence and incidence, together with access to care and treatment, present excellent conditions to further build on towards this objective. The Dutch national plan on viral hepatitis, introduced in 2016, defines targets in the HCV healthcare cascade and provides a structural framework for the development of elimination activities. Since many different stakeholders are involved in HCV care in the Netherlands, focus has been placed on micro-elimination initiatives as a pragmatic and efficient approach. These numerous micro-eliminations projects have brought the Netherlands closer to HCV elimination. In the near future, efforts specifically have to be made in order to optimize case-finding strategies and to successfully accomplish the nationwide implementation of the registration and monitoring system of viral hepatitis mono-infections, before this final goal can be reached. The upcoming years will then elucidate if the Dutch' hands on approach has resulted in sufficient progress against HCV and if the Netherlands will lead the way towards nationwide HCV elimination.
