One-step diagnosis strategy together with multidisciplinary telematics referral perform an effective approach for identifying and treating patients with active Hepatitis C infection. Ann Hepatol 2022; 27:100542. [PMID: 34571265 DOI: 10.1016/j.aohep.2021.100542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 04/04/2021] [Accepted: 04/05/2021] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND OBJECTIVES Implementation of a one-step strategy for diagnosis of active Hepatitis C virus (HCV) infection would encourage the early diagnosis and reduce the time to access antiviral treatments. The aim of this study was to evaluate the impact of a HCV one-step diagnosis compared to the traditional two-step protocol in terms of the time required for patients to be seen by specialists and the time taken to start antiviral treatment. MATERIAL AND METHODS A comparative study was carried out to assess two diagnostic algorithms (one-step and two-step) for active HCV infection. Serological markers were quantified using the same serum sample to determine both anti-HCV antibodies (HCV-Ab) and HCV core antigen (HCV-cAg) by Architect i2000 SR kit. In this period, a multidisciplinary procedure was started for telematics referral of viremic patients. RESULTS One-step approach reduced the time required for patient HCV diagnosis, referral to a specialist, access to treatment, and eliminated the loss of patients to follow-up. Significant differences were observed between one-step and two-step diagnosis methods in the time required for patients to be seen by a specialist (18 days [Interquartile range (IQR) = 14-42] versus 107 days [IQR = 62-148]) and for the initiation of treatment (54 days [IQR = 43-75] versus 200 days [IQR = 116-388]), mainly for patients with advanced fibrosis (35 days [IQR = 116-388] versus 126 days [IQR = 152-366]). CONCLUSIONS Use of HCV-cAg has proven to be a useful tool for screening patients with active hepatitis C. The development of a multidisciplinary protocol for the communication of results improved the efficiency of the care process.

Abstract
OBJECTIVE the aim of this study was to analyze the process of detection and treatment of hepatitis C in individuals experiencing homelessness (IEH). METHODS an analytical cross-sectional study was performed in a Primary Care center. The center screened and registered patients with a positive hepatitis C antibody test and referred them to the Digestive Service. RESULTS finally, 8.3 % presented with a positive HCV antibody test, of which six were patients who had already received treatment. Of those who had not received treatment, one patient was successfully treated; 30.8 % of the total could not be located or did not wish to participate. CONCLUSION community coordination and the use of rapid tests would improve detection.

Abstract
BACKGROUND AND AIM undiagnosed hepatitis C virus (HCV) infection and/or inadequate access to care are barriers to the elimination of HCV. Reflex testing has proven to facilitate referral to care, treatment and viral elimination. In this study, a reflex testing program was implemented in Andalusia and its impact on access to care was evaluated. PATIENTS AND METHODS an observational, retrospective and prospective study was performed across diagnostic laboratories responsible for HCV diagnosis in southern Spain. After surveying the barriers to performing reflex testing, the number of patients that were not referred for care in 2016 was retrospectively studied (pre-reflex cohort). Subsequently, several measures were proposed to overcome the identified barriers. Finally, reflex testing was implemented and its impact evaluated. RESULTS the pre-reflex cohort included information from 1,053 patients. Slightly more than half of the patients (n = 580; 55%) visited a specialist for treatment evaluation during a median period of 71 days (interquartile range = 35-134) since the date of diagnosis. The post-reflex cohort (September 2017 to March 2018) included 623 patients. Only 17% (n = 106) of the patients had not been referred for care or evaluated for treatment in a median period of 52 days (interquartile range = 28-86). CONCLUSIONS in 2016, nearly half of new HCV diagnoses in southern Spain were not referred for care. Barriers to the implementation of reflex testing were overcome in our study. Moreover, this strategy was effectively implemented in 2017. Reflex testing contributed to improving referral for care. This program will contribute to the micro-elimination of hepatitis C in Spain.

Abstract
BACKGROUND undiagnosed active hepatitis C virus (HCV) infection remains an obstacle towards its eradication. This study aimed to estimate the prevalence of HCV infection and to describe the diagnostic advances in Navarre, Spain. METHODS HCV-infection diagnostic performance was analyzed in Navarre's primary and specialized health care between 2017 and 2019. The prevalence of undiagnosed infections was estimated for patients with programmed surgeries unrelated to HCV infection, who underwent a routine HCV antibody (anti-HCV) determination. HCV-RNA (viral load) was quantified in anti-HCV positive cases. The prevalence was standardized according to the sex and age distribution in the general population. RESULTS from the 63,405 subjects examined for anti-HCV, 84 (five per 100,000 person-years) were diagnosed with an active infection. In Primary Health Care, 20,363 patients were analyzed and 47 active infections were detected, i.e. one case for every 433 people tested, implying 56 % of all identified active infections. On the other hand, 9,399 surgical patients were analyzed and 120 anti-HCV positive cases were detected (adjusted prevalence: 1.47 %; 95 % CI: 1.24-1.52). A positive viral load had been determined at any time in 66 cases (0.61 %), of which five were undiagnosed active infections (adjusted prevalence: 0.04 %; 95 % CI: 0.01-0.11). Preoperative screening allowed the detection of one undiagnosed infection per 795 people analyzed aged between 45 and 64 years. CONCLUSIONS Primary Health Care efficiently contributes to the detection of undiagnosed HCV active infections. This may be speeded up by performing population screening, targeting subjects between 45 and 64 years of age.

Abstract
BACKGROUND hepatitis C, besides health impairment, results in significant loss of productivity and diminished quality of life, and noticeably contributes to health expenditure increases. Because of all this, the Spanish Ministry of Health (Ministerio de Sanidad, Consumo y Bienestar Social - MSCBS) implemented in 2015 a strategic plan for managing hepatitis C (Plan Estratégico para el Abordaje de la Hepatitis C - PEAHC) within the National Health System. However, the PEAHC includes no screening plan. The MSCBS developed a framework document on population screening (Documento Marco sobre Cribado Poblacional) that defines the criteria a disease must meet in order to consider implementing a screening program. Specifically, it defines 4 criteria related to the health issue, 4 related to the screening test, and 3 criteria dealing with diagnosis confirmation and treatment. OBJECTIVE to identify whether there is scientific evidence to support hepatitis C meeting the criteria to be considered a disease qualifying for a population screening strategy in Spain. METHODS a literature search for scientific evidence concerning each required criterion for implementing a population screening plan for hepatitis C in Spain. RESULTS sufficient scientific evidence was found to support hepatitis C meeting the criteria required by the MSCBS for the implementation of a population screening program. CONCLUSIONS according to the available scientific evidence, hepatitis C in Spain meets the required criteria to qualify for consideration of population screening plan.

Abstract
The Spanish Association for the Study of the Liver (AEEH) is convinced that the elimination of hepatitis C virus (HCV) in Spain is possible as long as we are able to use the resources and tools necessary for it. This document reflects the position of the AEEH regarding the elimination of HCV, establishing a wide range of recommendations that can be grouped into five categories: 1) Screening of HCV according to age, of the existence of classic acquisition risk factors of infection, active search of previously diagnosed patients and development of microelimination strategies in vulnerable populations; 2) Simplification of HCV diagnosis (one-step diagnosis and diagnosis at the point of patient care); 3) Simplification of patient treatment and improvement of care circuits; 4) Health policy measures, and, finally, 5) Establishment of HCV elimination indicators.

Abstract
OBJECTIVES To examine HCV prevalence and management among people who inject drugs (PWID) attending primary care and community-based health services at four European sites using baseline data from a multicentre feasibility study of a complex intervention (HepLink). METHODS Primary care and community-based health services in Dublin, London, Bucharest and Seville were recruited from the professional networks of the HepLink consortium. Patients were eligible to participate if aged ≥18 years, on opioid substitution treatment or at risk of HCV (i.e. injecting drug use, homeless or incarcerated), and attended the service. Data on patient demographics and prior HCV management were collected on participants at baseline. RESULTS Twenty-nine primary care and community-based health services and 530 patients were recruited. Baseline data were collected on all participants. Participants' mean age ranged from 35 (Bucharest) to 51 years (London), with 71%-89% male. Prior lifetime HCV antibody testing ranged from 65% (Bucharest) to 95% (Dublin) and HCV antibody positivity among those who had been tested ranged from 78% (Dublin) to 95% (Bucharest). Prior lifetime HCV RNA testing among HCV antibody-positive participants ranged from 17% (Bucharest) to 84% (London). Among HCV antibody- or RNA-positive participants, prior lifetime attendance at a hepatology/infectious disease service ranged from 6% (London) to 50% (Dublin) and prior lifetime HCV treatment initiation from 3% (London) to 33% (Seville). CONCLUSIONS Baseline assessment of the HCV cascade of care among PWID attending primary care and community-based health services at four European sites identified key aspects of the care cascade at each site that need to be improved.

Abstract
Background Efficient strategies are needed in order to achieve the objective of the WHO of eradicating Hepatitis C virus (HCV). Hepatitis C infection can be eliminated by a combination of direct acting antiviral (DAA). The problem is that many individuals remain undiagnosed. The objective is to conduct a systematic review of the evidence on economic evaluations that analyze the screening of HCV followed by treatment with DAAs. Methods Eleven databases were performed in a 2015-2018-systematic review. Inclusion criteria were economic evaluations that included incremental cost-effectiveness ratio (ICER) in terms of cost per life year gained or quality-adjusted life year. Results A total of 843 references were screened. Sixteen papers/posters meet the inclusion criteria. Ten of them included a general population screening. Other populations included were baby-boomer, people who inject drugs, prisoners or immigrants. Comparator was “standard of care”, other high-risk populations or no-screening. Most of the studies are based on Markov model simulations and they mostly adopted a healthcare payer´s perspective. ICER for general population screening plus treatment versus high-risk populations or versus routinely performed screening showed to be below the accepted willingness to pay thresholds in most studies and therefore screening plus DAAs strategy is highly cost-effective. Conclusion This systematic review shows that screening programmes followed by DAAs treatment is cost-effective not only for high risk population but for general population too. Because today HCV can be easily cured and its long-term consequences avoided, a universal HCV screening plus DAAs therapies should be the recommended strategy to achieve the WHO objectives for HCV eradication by 2030.

Abstract
BACKGROUND Reflex testing is necessary to achieve the objectives of hepatitis C elimination. However, in 2017 only 31% of Spanish hospitals performed reflex test. As a consequence of that finding, reflex testing was recommended by scientific societies involved in the diagnosis and treatment of hepatitis C. OBJECTIVE To evaluate the degree of implementation of reflex testing in 2019 and to know the implementation of rapid diagnostic and/or dried blood spot testing (RDT and / or DBS) in Spanish hospitals. METHODS Cross-sectional study through a survey conducted in October 2019 to Spanish general hospitals with at least 200 beds, public or private with teaching accreditation. RESULTS 129 (80%) hospitals responded. Reflex testing is performed by 89% of the centers vs. 31% in 2017 (P<.001). From 2017 to 2019, centers using alerts to improve continuity of care increased from 69% to 86% (P=.002). In 2019, 11% of centers can determine anti-HCV in dried spot, 15% viremia in dried spot, 0.85% anti-HCV in saliva, and 37% of antibodies and/or viremia with point of care test. 43% of hospitals have at least one diagnostic method with RDT and/or DBS. CONCLUSION The implementation of reflex testing has increased significantly, reaching 89% of hospitals in 2019. The recommendations of scientific societies could have contributed to the implementation of reflex testing. On the other hand, access to RDT and/or DBS is insufficient and initiatives are needed to improve their implementation.

Abstract
BACKGROUND implementing one-step strategies for hepatitis C diagnosis would help shorten the time to treatment access. Thus avoiding disease progression and complications, while facilitating hepatitis C virus (HCV) elimination. OBJECTIVE to assess the validity and certainty of potential one-step strategies for the diagnosis of HCV infection and their associated cost and efficiency. METHODS the study design is an economic appraisal of efficiency (cost/efficacy) using decision trees and deterministic sensitivity analysis. The analysis was performed from the payer perspective (Spanish National Health System), which exclusively considers the direct costs. Only the differential costs (diagnostic testing costs) were taken into account and the study was set in Spain. The efficacy of a diagnostic strategy was defined as the percentage of patients with an active HCV infection who received a positive diagnosis and the efficiency was defined as the cost per patient with a correctly diagnosed and active infection. RESULTS the one-step strategies evaluated for the diagnosis of HCV had an acceptable validity and certainty due to the high sensitivity and specificity of the considered tests. The Ab-Ag strategy was the most efficient, followed by Ab-Ag-VL and Ab-VL. Ab-Ag was the most efficient due to the lower cost per patient tested, although the efficacy was lower than the Ab-VL efficacy. CONCLUSION the study findings may help to establish more appropriate one-step diagnostic approaches whilst considering the efficacy and efficiency.

Abstract
Accurate subtyping of hepatitis C virus genotype 1 (HCV-1) remains clinically and epidemiologically relevant. The Abbott HCV Genotype Plus RUO (GT Plus) assay, targeting the core region, was evaluated as a reflex test to resolve ambiguous HCV-1 results in a challenging sample collection. 198 HCV-1 specimens were analysed with GT Plus (38 specimens with and 160 without subtype assigned by the Abbott RealTime Genotype II (GT II) assay targeting the 5'NC and NS5B regions). Sanger sequencing of the core and/or NS5B regions were performed in 127 specimens without subtype assignment by GT II, with "not detected" results by GT Plus, or with mixed genotypes/subtypes. The remaining GT Plus results were compared to LiPA 2.0 (n = 45) or just to GT II results if concordant (n = 26). GT Plus successfully assigned the subtype in 142/160 (88.8%) samples. "Not detected" results indicated other HCV-1 subtypes/genotypes or mismatches in the core region in subtype 1b. The subtyping concordance between GT Plus and either sequencing or LiPA was 98.6% (140/142). Therefore, combined use of GT II and GT Plus assays represents a reliable and simple approach which considerably reduced the number of ambiguous HCV-1 results and enabled a successful subtyping of 98.9% of all HCV-1 samples.

Abstract
BACKGROUND Elimination of hepatitis C virus (HCV) infection requires high diagnostic rates and universal access to treatment. Around 40% of infected individuals are unaware of their infection, which indicates that effective screening strategies are needed. We analyzed the efficiency (incremental cost-utility ratio, ICUR) of 3 HCV screening strategies: a) general population of adults, b) high-risk groups, and c) population with the highest anti-HCV prevalence plus high-risk groups. METHODS An analytical decision model, projecting progression of the disease over a lifetime, was used to establish the candidate population for HCV screening. HCV data were obtained from the literature: anti-HCV prevalence (0.56%-1.54%), viremic patients (31.5%), and percentage of undiagnosed persons among those with viremia (35%). It was assumed that most patients would be treated and have HCV therapy response (98% SVR); transition probabilities, utilities, and disease management annual costs were obtained from the literature. Efficiency over the life of patients under the National Health System perspective was measured as quality-adjusted life years (QALY) and total cost (screening, diagnosis, pharmacological and disease management). A discount rate of 3% was applied to costs and outcomes. RESULTS Screening of the adult population would identify a larger number of additional chronic hepatitis C cases (N = 52,694) than screening the highest anti-HCV prevalence population plus high-risk groups (N = 42,027) or screening high-risk groups (N = 26,128). ICUR for the general population vs. high-risk groups was €8914/QALY gained per patient (€18,157 incremental cost and 2.037 QALY). ICUR for the general population vs. population with highest anti-HCV prevalence plus high-risk groups was €7,448/QALY gained per patient (€7,733 incremental cost and 1.038 QALY). These ICUR values are below the accepted efficiency threshold (€22,000-€30,000). CONCLUSION HCV screening and treatment of the general adult population is cost-effective compared to screening of high-risk groups or the population with the highest anti-HCV prevalence plus high-risk groups.

Abstract
PURPOSE The aim was to estimate seroprevalence and prevalence of hepatitis C virus (HCV) infection in a small health area of the Valencian Community, Spain. PATIENTS AND METHODS This is a descriptive cross-sectional study aimed at estimation of HCV infection prevalence in the whole adult population (25-70 years old), that is, a pilot study for an eventual population-based screening program. RESULTS A total of 5849 participants aged 25-70 years (51% male) were invited to participate by regular mail. Overall, 143 letters were returned owing to errors in the addresses. Of 5706 participants, 2637 (46.2%) participated in the study. Rapid test of anti-HCV antibody detection was positive in 30 cases (HCV seroprevalence 1.14%, 95% confidence intervals: 0.73-1.55%). Of those, seven were not aware of their condition. Participants who had a positive result in the rapid test of anti-HCV detection were given a confirmatory test by enzyme immune assay, and all had a positive result. RNA-HCV determination by quantitative PCR in positive anti-HCV patients showed positive viremia in 13 (43.3%) cases, of which five were not aware of the disease. Of the 17 patients who had negative viremia, two were unaware of their HCV status, one was a carrier of anti-HCV and was already aware of his condition, and 14 had been previously treated with satisfactory results. Regarding fibrosis, of the seven patients who were unaware of HCV infection, none of them had significant fibrosis. Moreover, 26 (86.7%) anti-HCV positive patients were reported to have one or more risk factors for HCV infection. CONCLUSION HCV screening strategies applied to the general population are good means to diagnose and treat patients who are not aware of their infection, avoiding new transmissions as well as disease progression.

MDM Policy Pract 2018; 3:2381468318776634. [PMID: 30288448 PMCID: PMC6157435 DOI: 10.1177/2381468318776634] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2018] [Accepted: 04/20/2018] [Indexed: 12/15/2022] Open
Abstract
The World Health Organization HCV Guideline Development Group is considering a "treat all" recommendation for persons infected with hepatitis C virus (HCV). We reviewed the model-based evidence of cost-effectiveness and population health impacts comparing expanded treatment policies to more limited treatment access policies, focusing primarily on evaluations of all-oral directly acting antivirals published after 2012. Searching PubMed, we identified 2,917 unique titles. Sequentially reviewing titles and abstracts identified 226 potentially relevant articles for full-text review. Sixty-nine articles met all inclusion criteria-42 cost-effectiveness analyses and 30 models of population-health impacts, with 3 articles presenting both types of analysis. Cost-effectiveness studies for many countries concluded that expanding treatment to people with mild liver fibrosis, who inject drugs (PWID), or who are incarcerated is generally cost-effective compared to more restrictive treatment access policies at country-specific prices. For certain patient subpopulations in some countries-for example, elderly individuals without fibrosis-treatment is only cost-effective at lower prices. A frequent limitation is the omission of benefits and consequences of HCV transmission (i.e., treatment as prevention; risks of reinfection), which may underestimate or overestimate the cost-effectiveness of a "treat all" policy. Epidemiologic modeling studies project that through a combination of prevention, aggressive screening and diagnosis, and prompt treatment for all fibrosis stages, it may be possible to virtually eliminate HCV in many countries. Studies show that if resources are not available to diagnose and treat all HCV-infected individuals, treatment prioritization may be needed, with alternative prioritization strategies resulting in tradeoffs between reducing mortality or reducing incidence. Notably, because most new HCV infections are among PWID in many settings, HCV elimination requires unrestricted treatment access combined with injection transmission disruption strategies. The model-based evidence suggests that a properly constructed strategy that substantially expands HCV treatment could achieve cost-effective improvements in population health in many countries.
