Abstract
BACKGROUND The treatment of chronic hepatitis C virus (HCV) infection using directly acting antivirals was recently adopted in the treatment guidelines of Zimbabwe. The objectives of this study were to design a simplified model of HCV care and estimate the cost of screening and treatment of hepatitis C infection at a tertiary hospital in Zimbabwe. METHODS We developed a model of care for HCV using WHO 2018 guidelines for the treatment of HCV infection and expert opinion. We then performed a micro-costing to estimate the costs of implementing the model of care from the healthcare sector perspective. Deterministic and probabilistic sensitivity analyses were performed to explore the impact of uncertainty in input parameters on the estimated total cost of care. RESULTS The total cost of screening and treatment was estimated to be US$2448 (SD=$290) per patient over a 12-week treatment duration using sofosbuvir/velpatasvir. The cost of directly acting antivirals contributed 57.5% to the total cost of care. The second largest cost driver was the cost of diagnosis, US$819, contributing 34.6% to the total cost of care. CONCLUSION Screening and treatment of HCV-infected individuals using directly acting antivirals at a tertiary hospital in Zimbabwe may require substantial financial resources.

Abstract
Hepatitis C virus (HCV) remains a major public health problem, despite the availability of effective treatments. In many areas, the ability to diagnose HCV infection at the point of care is key to scaling up access to care and treatment. To achieve this, an accurate, easy-to-use, and affordable diagnostic tool is required-this would enable decentralized testing and the creation of one-stop centers to eliminate gaps in the care cascade, which would help reach the millions of people with undiagnosed HCV infection in low- and middle-income countries and high-risk populations in high-income countries. In this review, we examine the current state of point-of-care molecular technologies, the advantages and limitations of currently available devices (both near- and true-point-of-care), the potential of molecular testing to transform diagnostic medicine in the future, and the challenges that need to be addressed for broader adoption of this technology in routine clinical practice.

Abstract
Introduction Primary care doctors (PCDs) play an increasingly important role in the management of hepatitis C. It is essential for PCDs to have good self-efficacy in screening and treating hepatitis C to achieve good outcomes. This study aimed to determine the knowledge and attitude towards and other factors associated with self-efficacy in screening and treating hepatitis C. Methods This cross-sectional study was conducted using an online Google Form. PCDs working at primary healthcare clinics were selected via simple random sampling. The online form contained items on sociodemographic and practice characteristics and a validated questionnaire on knowledge, attitude and self-efficacy towards screening and treating hepatitis C. Data were statistically analysed. Results A total of 242 PCDs were included in the analysis. The median age was 35 years (interquartile range [IQR]=5). The majority of the PCDs were women (83.9%) and Malay (71.9%) and had a median working experience of 6 years (IQR=6). The mean self-efficacy score was 12.67 (standard deviation=3.38). The factors associated with a higher level of self-efficacy in screening and treating hepatitis C were postgraduate qualification, training within the last one year, better knowledge and attitude scores and prior experience in treating hepatitis C. Conclusion The identified factors are crucial in improving the self-efficacy among PCDs in hepatitis C care services. Policymakers are suggested to implement training programmes and encourage continuous medical education, exposure to patient management and postgraduate certification in family medicine to help PCDs in treating hepatitis C better.

Usability and acceptability of oral fluid- and blood-based hepatitis C virus self-testing among the general population and men who have sex with men in Malaysia. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0001770. [PMID: 38170720 PMCID: PMC10763960 DOI: 10.1371/journal.pgph.0001770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Accepted: 11/20/2023] [Indexed: 01/05/2024]
Abstract
Hepatitis C self-testing (HCVST) is emerging as an additional strategy that could help to expand access to HCV testing. We conducted a study to assess the usability and acceptability of two types of HCVST, oral fluid- and blood-based, among the general population and men who have sex with men (MSM) in Malaysia. An observational study was conducted in three primary care centres in Malaysia. Participants who were layman users performed the oral fluid- and blood-based HCVST sequentially. Usability was assessed by calculating the rate of errors observed, the rate of difficulties faced by participants as well as inter-reader (self-test interpreted by self-tester vs interpreted by trained user) and inter-operator concordances (self-test vs test performed by trained user). The acceptability of HCV self-testing was assessed using an interviewer-administered semi-structured questionnaire. Participants were also required to read contrived test results which included "positive", "negative", and "invalid". There was a total of 200 participants (100 general population, 100 MSM; mean age 33.6 ± 14.0 years). We found a high acceptability of oral fluid- and blood-based HCVST across both general population and MSM. User errors, related to timekeeping and reading within stipulated time, were common. However, the majority of the participants were still able to obtain and interpret results correctly, including that of contrived results, although there was substantial difficulty interpreting weak positive results. The high acceptability of HCVST among the participants did not appreciably change after they had experienced both tests, with 97.0% of all participants indicating they would be willing to use HCVST again and 98.5% of them indicating they would recommend it to people they knew. There was no significant difference between the general population and MSM in these aspects. Our study demonstrates that both oral fluid- and blood-based HCVST are highly acceptable among both the general population and MSM. Both populations also showed comparable ability to conduct the tests and interpret the results. Overall, this study suggests that HCVST could be introduced as an addition to existing HCV testing services in Malaysia. Further studies are needed to establish the optimal positioning of self-testing alongside facility-based testing to expand access to HCV diagnosis in the country.

Cost-effectiveness of a decentralized, community-based "one-stop-shop" hepatitis C testing and treatment program in Yangon, Myanmar. JGH Open 2023; 7:755-764.

Abstract
Background and Aim The availability of direct-acting antiviral (DAA) treatment and point-of-care diagnostic testing has made hepatitis C (HCV) elimination possible even in low- and middle-income countries (LMICs); however, testing and treatment costs remain a barrier. We estimated the cost and cost-effectiveness of a decentralized community-based HCV testing and treatment program (CT2) in Myanmar. Methods Primary cost data included the costs of DAAs, investigations, medical supplies and other consumables, staff salaries, equipment, and overheads. A deterministic cohort-based Markov model was used to estimate the average cost of care, the overall quality-adjusted life years (QALYs) gained, and the incremental cost-effectiveness ratio (ICER) of providing testing and DAA treatment compared with a modeled counterfactual scenario of no testing and no treatment. Results From 30 January to 30 September 2019, 633 patients were enrolled, of whom 535 were HCV RNA-positive, 489 were treatment eligible, and 488 were treated. Lifetime discounted costs and QALYs of the cohort in the counterfactual no testing and no treatment scenario were estimated to be USD61790 (57 898-66 898) and 6309 (5682-6363) respectively, compared with USD123 248 (122 432-124 101) and 6518 (5894-6671) with the CT2 model of care, giving an ICER of USD294 (192-340) per QALY gained. This "one-stop-shop" model of care has a 90% likelihood of being cost-effective if benchmarked against a willingness to pay of US$300, which is 20% of Myanmar's GDP per capita (2020). Conclusions The CT2 model of HCV care is cost-effective in Myanmar and should be expanded to meet the National Hepatitis Control Program's 2030 target, alongside increasing the affordability and accessibility of services.

Public reimbursement policies in Canada for direct-acting antiviral treatment of hepatitis C virus infection: A descriptive study. CANADIAN LIVER JOURNAL 2023; 6:190-200.

Abstract
Background Direct-acting antiviral (DAA) therapies have simplified HCV treatment, and publicly funded Canadian drug plans have eliminated disease-stage restrictions for reimbursement of DAA therapies. However other policies which complicate, delay, or prevent treatment initiation still persist. We aim to describe these plans' existing reimbursement criteria and appraise whether they hinder treatment access. Methods We reviewed DAA reimbursement policies of 16 publicly funded drug plans published online and provided by contacts with in-depth knowledge of prescribing criteria. Data were collected from May to July 2022. Primary outcomes were: (1) if plans have arranged to accept point-of-care HCV RNA testing for diagnosis; testing requirements for (2) HCV genotype, (3) fibrosis stage, and (4) chronic infection; (5) time taken and method used to approve reimbursement requests; (6) providers eligible to prescribe DAAs; and (7) restrictions on re-treatment. Results Fifteen (94%) plans have at least one policy in place which limits simplified HCV treatment. Many plans continue to require results of genotype or fibrosis staging, limit eligible prescribers, and take longer than 1 day to approve coverage requests. One plan discourages treatment for re-infection. Conclusion Reimbursement criteria set by publicly funded Canadian drug plans continue to limit timely, equitable access to HCV treatment. Eliminating clinically irrelevant pre-authorization testing, expanding eligible prescribers, expediting claims processing, and broadening coverage of treatment for reinfection will improve access to DAAs. The federal government could further enhance efforts by introducing a federal HCV elimination strategy or federal high-cost drug PharmaCare program.

Assessing feasibility of a modified same-day test-and-treat model for hepatitis C among rural people who inject drugs. Harm Reduct J 2023; 20:48. [PMID: 37046294 PMCID: PMC10091347 DOI: 10.1186/s12954-023-00780-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 04/06/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND Despite advancements in hepatitis C virus (HCV) treatment, low uptake among hard-to-reach populations remains a global issue. The current study aimed to assess the feasibility of a modified same-day test-and-treat model in improving HCV care for people who inject drugs (PWID) living in resource-constrained rural areas. METHODS A pilot study was conducted in four primary healthcare (PHC) centers in Malaysia. The model's key features included on-site HCV ribonucleic acid (RNA) testing using a shared GeneXpert® system; noninvasive biomarkers for cirrhosis diagnosis; and extended care to PWID referred from nearby PHC centers and outreach programs. The feasibility assessment focused on three aspects of the model: demand (i.e., uptake of HCV RNA testing and treatment), implementation (i.e., achievement of each step in the HCV care cascade), and practicality (i.e., ability to identify PWID with HCV and expedite treatment initiation despite resource constraints). RESULTS A total of 199 anti-HCV-positive PWID were recruited. They demonstrated high demand for HCV care, with a 100% uptake of HCV RNA testing and 97.4% uptake of direct-acting antiviral treatment. The rates of HCV RNA positivity (78.4%) and sustained virologic response (92.2%) were comparable to standard practice, indicating the successful implementation of the model. The model was also practical, as it covered non-opioid-substitution-therapy-receiving individuals and enabled same-day treatment in 71.1% of the participants. CONCLUSIONS The modified same-day test-and-treat model is feasible in improving HCV care for rural PWID. The study finding suggests its potential for wider adoption in HCV care for hard-to-reach populations.

Abstract
This cross-sectional study evaluated the performance of the Aspartate Aminotransferase-to-Platelet Ratio Index (APRI) and the Fibrosis-4 (FIB-4) Index when they were used individually and in sequential combination to diagnose cirrhosis associated with hepatitis C virus infection. The final evaluation involved 906 people living with hepatitis C. The diagnostic performance of individual biomarkers at cut-off scores of 1.5 and 2.0 for the APRI and at 3.25 for the FIB-4 index was assessed. For the sequential combination method, the cirrhosis status of individuals with an APRI score between 1.0 and 1.5 were reassessed using the FIB-4. Transient elastography (TE) was used as the reference standard for diagnosing cirrhosis. The APRI, at a cut-off score of 1.5, showed a sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 44.9%, 97.6%, 91.1% and 76.3%, respectively. Increasing the cut-off score to 2.0 produced a much lower sensitivity (29.6%) and NPV (71.9%). The FIB-4, at a cut-off score of 3.25, yielded a sensitivity, specificity, PPV and NPV of 40.8%, 97.3%, 89.1% and 75.0%, respectively. The sequential combination method demonstrated a much more optimal diagnostic performance (50.2% sensitivity, 96.6% specificity, 89.0% PPV and 77.9% NPV). Overall, the APRI and FIB-4 Index performed better in diagnosing cirrhosis associated with hepatitis C when they were used in sequential combination.
