Abstract
INTRODUCTION Diagnostics are an essential, undervalued part of the health-care system. For many diseases, molecular diagnostics are the gold standard, but are not easy to implement in Low- and Middle-Income Countries (LMIC). Sample-to-result (S2R) platforms combining all procedures in a closed system could offer a solution. In this paper, we investigated their suitability for implementation in LMIC. AREAS COVERED A scorecard was used to evaluate different platforms on a range of parameters. Most platforms scored fairly on the platform itself, ease-of-use and test consumables; however, shortcomings were identified in cost, distribution and test panels tailored to LMIC needs. The diagnostic coverage for common infectious diseases was found to have a wider coverage in high-income countries (HIC) than LMIC. A literature study showed that in LMIC, these platforms are mainly used as diagnostic tools or evaluation of diagnostic performance, with a minority assessing the operational characteristics or the clinical utility. In this narrative review, we identified various points for adaptation of S2R platforms to LMIC conditions. EXPERT OPINION For S2R platforms to be suitable for implementation in LMIC some modifications by the manufacturers could be considered. Furthermore, strengthening health systems and digitalization are vital; as are smaller, cheaper, faster, and sustainable technologies.

Implementation of a mobile health clinic framework for Hepatitis C virus screening and treatment: a descriptive study. LANCET REGIONAL HEALTH. AMERICAS 2024; 29:100648. [PMID: 38124995 PMCID: PMC10733089 DOI: 10.1016/j.lana.2023.100648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 11/21/2023] [Accepted: 11/28/2023] [Indexed: 12/23/2023]
Abstract
Background Although treatment for Hepatitis C Virus (HCV) is effective, individuals face access barriers. The utility of mobile health clinics (MHC), effective mechanisms for providing healthcare to underserved populations, is understudied for HCV-related interventions. We aimed to describe implementation of, and factors associated with, screening and treatment via MHCs. Methods Clemson Rural Health implemented a novel MHC program to reach and treat populations at-risk for HCV with a focus on care for uninsured individuals. We examined HCV screening and treatment initiation/completion indicators between May 2021 and January 2023. Findings Among 607 individuals screened across 31 locations, 94 (15.5%) tested positive via antibody and viral load testing. Treatment initiation and completion rates were 49.6% and 86.0%, respectively. Among those screened, the majority were male (57.5%), White (61.3%; Black/Hispanic: 28.2%/7.7%), and without personal vehicle as primary transportation mode (54.4%). Injection drug use (IDU) was 27.2% and uninsured rate was 42.8%. Compared to HCV-negative, those infected included more individuals aged 30-44 (52.1% vs. 36.4%, p = 0.023), male (70.2% vs. 55.2%, p = 0.009), White (78.5% vs. 60.2%, p < 0.0001), without personal vehicle (58.5% vs. 43.5%, p = 0.028), IDU (83.7% vs. 21.0%, p < 0.0001), and uninsured (61.2% vs. 48.8%, p = 0.050). Uninsured rates were higher among those initiating compared to not initiating treatment (74.5% vs. 45.3%, p = 0.004). Interpretation The MHC framework successfully reaching its target population: at-risk individuals with access barriers to healthcare. The high HCV screening and treatment initiation/completion rates demonstrate the utility of MHCs as effective and acceptable intervention settings among historically difficult-to-treat populations.

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. [PMID: 38034058 PMCID: PMC10684991 DOI: 10.1002/jgh3.12978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 09/15/2023] [Accepted: 09/28/2023] [Indexed: 12/02/2023]
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.

Abstract
Hepatitis C (HCV) infection elimination in low- and middle-income countries requires decentralised HCV services to increase testing and linkage to care. The CT2 Study investigated patients' views of access to and acceptance of two community-based HCV care models in Myanmar using a mixed-methods approach. Point-of-care HCV testing and general practitioner-initiated HCV treatment were provided at two community clinics in Yangon, Myanmar-the Burnet Institute's (BI) clinic focused on people who inject drugs (PWID), and the Myanmar Liver Foundation's (MLF) clinic focused on people with liver-related diseases. Study staff administered quantitative questionnaires to 633 participants receiving anti-HCV antibody testing. Purposive sampling was used to recruit 29 participants receiving direct-acting antiviral treatment for qualitative interviews. Among participants completing quantitative questionnaires, almost all reported the clinic location was convenient (447/463, 97%), waiting time was acceptable (455/463, 98%), and HCV antibody and RNA testing methods were acceptable (617/632, 98% and 592/605, 97% respectively). Nearly all participants were satisfied with their clinic's services (444/463, 96%) and preferred same-day test results (589/632, 93%). BI clinic participants were more confident that they understood HCV antibody and RNA results; MLF clinic participants were more comfortable disclosing their risk behaviour to staff and had slightly higher satisfaction with the overall care, privacy and secure storage of their information. In qualitative interviews, participants reported that flexible appointment scheduling, short wait times and rapid return of results increased the clinic's accessibility. The simplified point-of-care testing and treatment procedures and supportive healthcare providers contributed to participants' acceptance of the HCV care model. This decentralised community-based HCV testing and treatment model was highly accessible and acceptable to CT2 participants. Prioritizing patient-centred care, rapid provision of results, flexible appointments and convenient clinic locations can promote accessible and acceptable services which may in turn help accelerate progress in reaching HCV elimination targets.

Abstract
OBJECTIVES Given limited data on factors associated with hepatitis C virus (HCV) treatment discontinuation and failure in low- and middle-income countries, we aimed to describe patient populations treated for HCV in five countries and identify patient groups that may need additional support. DESIGN Retrospective cohort analysis using routinely collected data. SETTING Public sector HCV treatment programmes in India (Punjab), Indonesia, Myanmar, Nigeria (Nasarawa) and Vietnam. PARTICIPANTS 104 957 patients who initiated treatment in 2016-2022 (89% from Punjab). PRIMARY OUTCOMES Treatment completion and cure. RESULTS Patient characteristics and factors associated with outcomes varied across countries and facilities. Across all patients, median age was 40 years (IQR: 29-52), 30.6% were female, 7.0% reported a history of injecting drugs, 18.2% were cirrhotic and 4.9% were coinfected with HIV. 79.8% were prescribed sofosbuvir+daclastasvir. Of patients with adequate follow-up, 90.6% (89,551) completed treatment. 77.5% (69,426) of those who completed treatment also completed sustained virological testing at 12 weeks (SVR12), and of those, 92.6% (64 305) were cured. In multivariable-adjusted models, in most countries, significantly lower treatment completion was observed among patients on 24-week regimens (vs 12-week regimens) and those initiated in later years of the programme. In several countries, males, younger patients <20 years and certain groups of cirrhotic patients were less likely to complete treatment or be cured. In Punjab, treatment completion was also lower in those with a family history of HCV and people who inject drugs (PWID); in other countries, outcomes were comparable for PWID. CONCLUSION High proportions of patients completed treatment and were cured across patient groups and countries. SVR12 follow-up could be strengthened. Males, younger people and those with decompensated cirrhosis on longer regimens may require additional support to complete treatment and achieve cure. Adequate programme financing, minimal user fees and implementation of evidence-based policies will be critical to close gaps.

Viral hepatitis and the cascade of care among people living with HIV in the Asia-Pacific. HIV Med 2022; 23:959-968. [PMID: 35218151 PMCID: PMC9402797 DOI: 10.1111/hiv.13280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 02/03/2022] [Accepted: 02/10/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Although the prevalence and mortality of hepatitis is high in the Asia-Pacific region, few studies are available on the diagnosis, treatment, and cure rates for viral hepatitis among people living with HIV in this area. This study aims to report the cascade of care (CoC) for hepatitis B (HBV) and C (HCV) among people living with HIV receiving combined antiretroviral therapy (ART). METHODS Patients enrolled in the TREAT Asia HIV Observational Database Low Intensity Transfer (TAHOD-LITE) cohort, on ART, and with follow-up data from 2010 to 2019 were included. Patients were determined as positive for HCV or HBV co-infection if they ever tested positive for HCV antibody (anti-HCV) or HBV surface antigen (HBsAg), respectively. RESULTS In total, 39% (8612/22 340) of the adult HIV cohort had undergone HBsAg testing, with 8% (672/8612) testing positive. HBV CoC demonstrated that 71% (474/672) of those with HBsAg positive results initiated treatment, 67% (318/474) of those on treatment had HBV DNA testing to evaluate treatment progression, and 18% (58/318) of those tested reached viral suppression. Of the cohort, 37% (8231/22 340) had anti-HCV testing, of whom 10% (779/8231) tested positive. The HCV CoC showed that 68% (526/779) of those with positive anti-HCV tests had HCV RNA tests, of whom 51% (267/526) had detectable HCV RNA. Among those with detectable HCV RNA, 65% (174/267) initiated HCV treatment. Of the 40% (69/174) who initiated HCV treatment, 90% (62/69) reached sustained virological response. CONCLUSION Our findings identified less frequent testing in the healthcare system and limited access to treatment as gaps in the CoC for viral hepatitis. More routine HCV RNA and HBV DNA testing is required for patients with positive screening tests to identify those in need of treatment.

Access to needles and syringes and methadone maintenance therapy among people who inject drugs in Yangon, Myanmar: a qualitative study. Harm Reduct J 2022; 19:107. [PMID: 36175872 PMCID: PMC9520098 DOI: 10.1186/s12954-022-00692-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Accepted: 09/25/2022] [Indexed: 12/03/2022] Open
Abstract
Background Access to sterile needles, syringes and methadone maintenance therapy (MMT) is critical to reduce the prevalence of bloodborne virus infections among people who inject drugs (PWID). We aimed to explore the experiences of PWID with respect to accessing needles/syringes services and MMT in Yangon, Myanmar.
Methods Burnet Institute implemented a community-based hepatitis C testing and treatment (CT2) program for PWID with on-site needles and syringes distribution. Separate from CT2, MMT was available at two government-run sites in Yangon. We conducted in-depth interviews with 15 PWID who received hepatitis C care in this program. Interviews were transcribed verbatim and translated into English. Thematic data analysis was performed using NVivo12 software.
Results Self-reported changes to needles/syringes sharing behaviour after hepatitis C education in the CT2 program and commencement of treatment were observed. One third of participants reported they became aware of the risks of sharing and reusing needles/syringes, and consequently refrained from sharing after the CT2 program. Inadequate availability of NSPs, cost of needles/syringes, and issues maintaining privacy when accessing needles/syringes emerged as key barriers to accessibility of needles/syringes. Participants described difficulties in accessing free needles/syringes. They were not aware of other free needles/syringes services at the time of the interview. Purchasing needles/syringes from pharmacies had privacy and confidentiality concerns. Structural barriers to accessibility of MMT were identified for both MMT sites in Yangon. Of the two MMT sites in Yangon, participants reported that the Ywarthargyi center had strict eligibility criteria for take-home methadone and transportation issues as it was located in the outskirt of the town. The Thingyangyun center was in a more convenient location, but only offered daily observed doses and had a long waiting time which was burdensome for some employed participants.
Conclusion Expansion of free needles/syringes services and adaptations of MMT to consider the needs and individual preferences of PWID will improve their access to these services and would likely reduce injecting related harms.

Abstract
All patients should have access to accurate and timely test results. The introduction of point of care testing (PoCT) for infectious diseases has facilitated access to those unable to access traditional laboratory-based medical testing, including those living in remote and regional locations, or individuals who are marginalized or incarcerated individuals. In many countries, laboratory testing for infectious diseases, such as hepatitis C virus (HCV), is performed in a highly regulated environment. However, this is not the case for PoCT, where testing is performed by non-laboratory staff and quality controls are often lacking. An assessment of the provision of laboratory-based quality assurance to PoCT for infectious disease was conducted and the barriers to participation identified. A novel approach to providing quality assurance to PoCT sites, in particular those testing for HCV, was designed and piloted. This novel approach incudes identifying and validating sample types that are inactivated and stable at ambient temperature, creating cost-effective supply chains to facilitate logistics of samples, and the development of a smart phone-enabled portal for data entry and analyses. The creation and validation of this approach to quality assurance of PoCT removes the barriers to participation and acts to improve the quality and accuracy of testing, reduce errors and waste, and improve patient outcomes.

Abstract
OBJECTIVES To assess the feasibility considerations for a decentralised, one-stop-shop model of care implemented in Yangon, Myanmar. SETTING Two primary care level clinics in urban Yangon, Myanmar. DESIGN This is a feasibility study of a highly effective care model. Using Intervention Complexity Framework by Gericke et al, we collated and analysed programmatic data and evaluation data to outline key project implementation requirements and experiences. PARTICIPANTS Programmatic data were collected from clinical records, GeneXpert device test and maintenance reports, national guidelines, product and device instructions and site monitoring visit reports. Healthcare providers involved in delivering care model contributed interview data. RESULTS The main feasibility considerations are appropriate storage for test kits and treatments (in response to temperature and humidity requirements), installation of a continuous stable electricity supply for the GeneXpert device, air-conditioning for the laboratory room hosting GeneXpert, access to a laboratory for pretreatment assessments and clear referral pathways for specialist consultation when required. Lessons from our project implementation experiences included the extensive time requirements for patient education, the importance of regular error monitoring and stock storage reviews and that flexible appointment scheduling and robust reminder system likely contributed to high retention in care. CONCLUSIONS Detailed documentation and dissemination of feasibility requirements and implementation considerations is vital to assist others to successfully implement a similar model of care elsewhere. We provide 10 recommendations for successful implementation. TRIAL REGISTRATION NUMBER The trial was registered at ClinicalTrials.gov NCT03939013 on May 6, 2019. This manuscript presents post-results data on feasibility.

[PMID: 34153155 PMCID: PMC8596916 DOI: 10.1111/liv.14983] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 05/28/2021] [Accepted: 06/14/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND With the advent of low-cost generic direct-acting antivirals (DAA), hepatitis C (HCV) elimination is now achievable even in low-/middle-income settings. We assessed the feasibility and effectiveness of a simplified clinical pathway using point-of-care diagnostic testing and non-specialist-led care in a decentralized, community-based setting. METHODS This feasibility study was conducted at two sites in Yangon, Myanmar: one for people who inject drugs (PWID), and the other for people with liver disease. Participants underwent on-site rapid anti-HCV testing and HCV RNA testing using GeneXpert(R) . General practitioners determined whether participants started DAA therapy immediately or required specialist evaluation. Primary outcome measures were progression through the HCV care cascade, including uptake of RNA testing and treatment, and treatment outcomes. FINDINGS All 633 participants underwent anti-HCV testing; 606 (96%) were anti-HCV positive and had HCV RNA testing. Of 606 tested, 535 (88%) were RNA positive and had pre-treatment assessments; 30 (6%) completed specialist evaluation. Of 535 RNA positive participants, 489 (91%) were eligible to initiate DAAs, 477 (98%) completed DAA therapy and 421 achieved SVR12 (92%; 421/456). Outcomes were similar by site: PWID site: 91% [146/161], and liver disease site: 93% [275/295]). Compensated cirrhotic patients were treated in the community; they achieved an SVR12 of 83% (19/23). Median time from RNA test to DAA initiation was 3 days (IQR 2-5). CONCLUSIONS Delivering a simplified, non-specialist-led HCV treatment pathway in a decentralized community setting was feasible in Yangon, Myanmar; retention in care and treatment success rates were very high. This care model could be integral in scaling up HCV services in Myanmar and other low- and middle-income settings.

Scott N, Win TM, Tidhar T, Htay H, Draper B, Aung PTZ, Xiao Y, Bowring A, Kuschel C, Shilton S, Kyi KP, Naing W, Aung KS, Hellard M. Hepatitis C elimination in Myanmar: Modelling the impact, cost, cost-effectiveness and economic benefits. LANCET REGIONAL HEALTH-WESTERN PACIFIC 2021; 10:100129. [PMID: 34327345 PMCID: PMC8315611 DOI: 10.1016/j.lanwpc.2021.100129] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 02/25/2021] [Accepted: 03/01/2021] [Indexed: 02/07/2023]
Abstract
Background Myanmar has set national hepatitis C (HCV) targets to achieve 50% of people diagnosed and 50% treated by 2030. The WHO has additional targets of reducing incidence by 80% and mortality by 65% by 2030. We aimed to estimate the impact, cost, cost-effectiveness and net economic benefit of achieving these targets. Methods Mathematical models of HCV transmission, disease progression and the care cascade were calibrated to 15 administrative regions of Myanmar. Cost data were collected from a community testing and treatment program in Yangon. Three scenarios were projected for 2020-2030: (1) baseline (current levels of testing/treatment); and testing/treatment scaled up sufficiently to reach (2) the national strategy targets; and (3) the WHO targets. Findings Without treatment scale-up, 333,000 new HCV infections and 97,000 HCV-related deaths were estimated to occur in Myanmar 2020-2030, with HCV costing a total $100 million in direct costs (testing, treatment, disease management) and $10.4 billion in lost productivity. In the model, treating 55,000 people each year was sufficient to reach the national strategy targets and prevented a cumulative 40,000 new infections (12%) and 25,000 HCV-related deaths (25%) 2020-2030. This was estimated to cost a total $189 million in direct costs ($243 per DALY averted compared to no treatment scale-up), but only $9.8 billion in lost productivity, making it cost-saving from a societal perspective by 2024 with an estimated net economic benefit of $553 million by 2030. Reaching the WHO targets required further treatment scale-up and additional direct costs but resulted in greater longer-term benefits. Interpretation Current levels of HCV testing and treatment in Myanmar are insufficient to reach the national strategy targets. Scaling up HCV testing and treatment in Myanmar to reach the national strategy targets is estimated to generate significant health and economic benefits. Funding Gilead Sciences.

HCV screening based on dried blood samples and linkage to care in people who use drugs: A prospective study. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 92:103134. [PMID: 33517130 DOI: 10.1016/j.drugpo.2021.103134] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 01/11/2021] [Accepted: 01/20/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND The burden of hepatitis C virus (HCV) infection among people who use drugs (PWUDs) is considerable. We aimed to screen for HCV infection using the fingerstick dried blood spot (DBS) test and to describe the cascade of hepatitis C care among PWUDs in Madrid, Spain. We also evaluated the prevalence of hepatitis B virus (HBV) and hepatitis D virus (HDV) in this population. METHODS We carried out a prospective study and collected samples and epidemiological data using a mobile unit. Viral infections were tested by immunoassay and RT-PCR assay. PWUDs with a positive result were contacted and referred to a specialized health center to confirm and treat the HCV infection. RESULTS We studied 529 PWUD samples; 49.7% were from persons who had previously used injection drugs (IDUs). Of these, 152 (28.7%) were positive for HCV antibodies, 122 (23.1%) for HCV RNA, 23 (4.3%) for HBsAg, and two (0.4%) for HDV antibodies (8.7% of those with hepatitis B). People who inject drugs (PWID) more frequently had positive HCV antibody titers (52% vs. 7.3%; p<0.001) and a positive HCV RNA test result (40.2% vs. 7.3%; p<0.001) than non-PWID. The time from sample collection to test results was 19 days. The next 104 individuals (85.2%) with active HCV infection were contacted to report their HCV test results. Of these, 63 (51.6%) had an appointment, 62 (50.8%) were evaluated in the hospital, and 56 (45.9%) started HCV therapy. CONCLUSION HCV screening using fingerstick DBS was an excellent tool for determining HCV prevalence and other chronic hepatitis viruses (HBV and HDV) in PWUDs. However, linkage to care was limited, mainly with respect to the initiation of HCV therapy.
