Community-Led Monitoring: When Community Data Drives Implementation Strategies.

PURPOSE OF REVIEW: Communities occupy a central position in effective health systems, notably through monitoring of health service quality and by giving recipients of care a voice. Our review identifies community-led monitoring mechanisms and best practices. RECENT FINDINGS: Implementation of community-led monitoring mechanisms improved service delivery at facility-level, health system-wide infrastructure and health outcomes among recipients of care. Successful models were community-led, collaborative, continuous and systematic, and incorporated advocacy and community education. Identifying and replicating successful community-led monitoring practices is a key pathway to equitable access to HIV and health services overall.

The impact of the COVID-19 pandemic on harm reduction services in Spain.

BACKGROUND: Containment policies and other restrictions introduced by the Spanish government in response to the COVID-19 pandemic present challenges for marginalised populations, such as people who use drugs. Harm reduction centres are often linked to social services, mental health services, and infectious disease testing, in addition to tools and services that help to reduce the harms associated with injecting drugs. This study aimed to explore the impact of the pandemic on these services in four autonomous communities in Spain. METHODS: This is a cross-sectional study that employed a seven-section structured survey administered electronically to 20 centres in July 2020. Data from the most heavily affected months (March-June) in 2020 were compared to data from the same period in 2019. Averages were calculated with their ranges, rates, and absolute numbers. RESULTS: All 11 responding centres reported having had to adapt or modify their services during the Spanish state of alarm (14 March-21 June 2020). One centre reported complete closure for 2 months and four reported increases in their operating hours. The average number of service users across all centres decreased by 22% in comparison to the same period in the previous year and the average needle distribution decreased by 40% in comparison to 2019. Most centres reported a decrease in infectious disease testing rates (hepatitis B and C viruses, human immunodeficiency virus, and tuberculosis) for March, April, and May in 2020 compared to the previous year. Reported deaths as a result of overdose did not increase during the state of alarm, but 2/11 (18%) centres reported an increase in overdose deaths immediately after finalisation of the state of alarm. CONCLUSION: Overall, Spanish harm reduction centres were able to continue operating and offering services by adjusting operating hours. The number of overall service users and needles distributed fell during the Spanish state of alarm lockdown period, suggesting that fewer clients accessed harm reduction services during this time, putting them at greater risk of reusing or sharing injecting equipment, overdosing, acquiring infectious diseases with decreased access to testing or discontinuing ongoing treatment such as methadone maintenance therapy, hepatitis C treatment, or antiretroviral therapy.

Innovative strategies for the elimination of viral hepatitis at a national level: A country case series.

Viral hepatitis is a leading cause of morbidity and mortality worldwide, but has long been neglected by national and international policymakers. Recent modelling studies suggest that investing in the global elimination of viral hepatitis is feasible and cost-effective. In 2016, all 194 member states of the World Health Organization endorsed the goal to eliminate viral hepatitis as a public health threat by 2030, but complex systemic and social realities hamper implementation efforts. This paper presents eight case studies from a diverse range of countries that have invested in responses to viral hepatitis and adopted innovative approaches to tackle their respective epidemics. Based on an investment framework developed to build a global investment case for the elimination of viral hepatitis by 2030, national activities and key enablers are highlighted that showcase the feasibility and impact of concerted hepatitis responses across a range of settings, with different levels of available resources and infrastructural development. These case studies demonstrate the utility of taking a multipronged, public health approach to: (a) evidence-gathering and planning; (b) implementation; and (c) integration of viral hepatitis services into the Agenda for Sustainable Development. They provide models for planning, investment and implementation strategies for other countries facing similar challenges and resource constraints.

Adherence to response-guided pegylated interferon and ribavirin for people who inject drugs with hepatitis C virus genotype 2/3 infection: the ACTIVATE study.

BACKGROUND: The aims of this analysis were to investigate treatment completion and adherence among people with ongoing injecting drug use or receiving opioid substitution therapy (OST) in a study of response-guided therapy for chronic HCV genotypes 2/3 infection. METHODS: ACTIVATE was a multicenter clinical trial recruited between 2012 and 2014. Participants with genotypes 2/3 were treated with directly observed peg-interferon alfa-2b (PEG-IFN) and self-administered ribavirin for 12 (undetectable HCV RNA at week 4) or 24 weeks (detectable HCV RNA at week 4). Outcomes included treatment completion, PEG-IFN adherence, ribavirin adherence, and sustained virological response (SVR, undetectable HCV RNA >12 weeks post-treatment). RESULTS: Among 93 people treated, 59% had recently injected drugs (past month), 77% were receiving OST and 56% injected drugs during therapy. Overall, 76% completed treatment. Mean on-treatment adherence to PEG-IFN and ribavirin were 98.2% and 94.6%. Overall, 6% of participants missed >1 dose of PEG-IFN and 31% took <95% of their prescribed ribavirin., Higher treatment completion was observed among those receiving 12 vs. 24 weeks of treatment (97% vs. 46%, P < 0.001) while the proportion of participants with 95% on-treatment ribavirin adherence was similar between groups (67% vs. 72%, P = 0.664). Receiving 12 weeks of therapy was independently associated with treatment completion. No factors were associated with 95% RBV adherence. Neither recent injecting drug use at baseline nor during therapy was associated with treatment completion or adherence to ribavirin. In adjusted analysis, treatment completion was associated with SVR (aOR 23.9, 95% CI 2.9-193.8). CONCLUSIONS: This study demonstrated a high adherence to directly observed PEG-IFN and self-administered ribavirin among people with ongoing injecting drug use or receiving OST. These data also suggest that shortening therapy from 24 to 12 weeks can lead to improved treatment completion. Treatment completion was associated with improved response to therapy. ACTIVATE trial registration number: NCT01364090 - May 31, 2011.

Toward a more accurate estimate of the prevalence of hepatitis C in the United States.

UNLABELLED: Data from the 2003-2010 National Health and Nutrition Examination Survey (NHANES) indicate that about 3.6 million people in the United States have antibodies to the hepatitis C virus, of whom 2.7 million are currently infected. NHANES, however, excludes several high-risk populations from its sampling frame, including people who are incarcerated, homeless, or hospitalized; nursing home residents; active-duty military personnel; and people living on Indian reservations. We undertook a systematic review of peer-reviewed literature and sought out unpublished presentations and data to estimate the prevalence of hepatitis C in these excluded populations and in turn improve the estimate of the number of people with hepatitis C in the United States. The available data do not support a precise result, but we estimated that 1.0 million (range 0.4 million-1.8 million) persons excluded from the NHANES sampling frame have hepatitis C virus antibody, including 500,000 incarcerated people, 220,000 homeless people, 120,000 people living on Indian reservations, and 75,000 people in hospitals. Most are men. An estimated 0.8 million (range 0.3 million-1.5 million) are currently infected. Several additional sources of underestimation, including nonresponse bias and the underrepresentation of other groups at increased risk of hepatitis C that are not excluded from the NHANES sampling frame, were not addressed in this study. CONCLUSION: The number of US residents who have been infected with hepatitis C is unknown but is probably at least 4.6 million (range 3.4 million-6.0 million), and of these, at least 3.5 million (range 2.5 million-4.7 million) are currently infected; additional sources of potential underestimation suggest that the true prevalence could well be higher.

Restrictions for Medicaid Reimbursement of Sofosbuvir for the Treatment of Hepatitis C Virus Infection in the United States.

The aim of this study was to systematically evaluate state Medicaid policies for the treatment of hepatitis C virus (HCV) infection with sofosbuvir in the United States. Medicaid reimbursement criteria for sofosbuvir were evaluated in all 50 states and the District of Columbia. The authors searched state Medicaid Web sites between 23 June and 7 December 2014 and extracted data in duplicate. Any differences were resolved by consensus. Data were extracted on whether sofosbuvir was covered and the criteria for coverage based on the following categories: liver disease stage, HIV co-infection, prescriber type, and drug or alcohol use. Of the 42 states with known Medicaid reimbursement criteria for sofosbuvir, 74% limit sofosbuvir access to persons with advanced fibrosis (Meta-Analysis of Histologic Data in Viral Hepatitis [METAVIR] fibrosis stage F3) or cirrhosis (F4). One quarter of states require persons co-infected with HCV and HIV to be receiving antiretroviral therapy or to have suppressed HIV RNA levels. Two thirds of states have restrictions based on prescriber type, and 88% include drug or alcohol use in their sofosbuvir eligibility criteria, with 50% requiring a period of abstinence and 64% requiring urine drug screening. Heterogeneity is present in Medicaid reimbursement criteria for sofosbuvir with respect to liver disease staging, HIV co-infection, prescriber type, and drug or alcohol use across the United States. Restrictions do not seem to conform with recommendations from professional organizations, such as the Infectious Diseases Society of America and the American Association for the Study of Liver Diseases. Current restrictions seem to violate federal Medicaid law, which requires states to cover drugs consistent with their U.S. Food and Drug Administration labels.

Simplification of antiviral hepatitis C virus therapy to support expanded access in resource-limited settings.

Currently, access to treatment for HCV is limited, with treatment rates lowest in the more resource-limited countries, including those countries with the highest prevalence. The use of oral DAAs has the potential to provide treatment at scale by offering opportunities to simplify drug regimens, laboratory requirements, and service delivery models. Key desirable characteristics of future HCV treatment regimens include high efficacy, tolerability, pan-genotype activity, short treatment duration, oral therapy, affordability, and availability as fixed-dose combination. Using such a regimen, HCV treatment delivery could be greatly simplified. Treatment could be initiated following confirmation of the presence of viraemia, with an initial assessment of the stage of liver disease. A combination DAA therapy that is safe and effective across genotypes could remove the need for genotyping and intermediary viral load assessments for response-guided therapy and reduce the need for adverse event monitoring. Simpler, safer, shorter therapy will also facilitate simplified service delivery, including task shifting, decentralization, and integration of treatment and care. The opportunity to scale up HCV treatment using such delivery approaches will depend on efforts needed to guarantee that the new DAAs are affordable in low-income settings. This will require the engagement of all stakeholders, ranging from the companies developing these new treatments, WHO and other international organizations, including procurement and funding mechanisms, governments and civil society.

Management of hepatitis C virus/HIV coinfection among people who use drugs in the era of direct-acting antiviral-based therapy.

Where active antiretroviral therapy (ART) is accessible, human immunodeficiency virus (HIV) is a survivable illness and effective ART can reduce HIV transmission. Chronic hepatitis C virus (HCV) has emerged as a threat to the survival of individuals harboring both HCV and HIV, due to high prevalence and aggressive disease course. The HCV/HIV coinfection epidemic has been driven by people who inject drugs (PWID), although incident HCV is rising among HIV-infected men who have sex with men in the absence of drug injection. Coinfected individuals warrant aggressive treatment of both viruses; although early ART initiation is recommended to reduce the rate of liver disease progression, the most effective way to decrease HCV-related morbidity and mortality in coinfection is to achieve HCV viral eradication. Direct-acting antiviral (DAA) agents will soon revolutionize HCV treatment. Clinical data are needed regarding the efficacy of DAAs in coinfected PWID. Drug-drug interaction studies between ART, DAAs, and opiate substitution therapy must be expedited. Coinfected PWID should have equitable and universal access to HIV/AIDS, HCV, and addiction prevention, care, and treatment. Essential basic steps include improving screening for both infections and engaging coinfected PWID in HIV and HCV care early after diagnoses. Developing strategies to expand access to HCV therapy for coinfected PWID is imperative to stem the HCV epidemic and limit the morbidity and mortality of those at greatest risk for HCV disease progression. The ultimate goal must be the elimination of HCV from all coinfected PWID.

Recommendations for the management of hepatitis C virus infection among people who inject drugs.

In the developed world, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). The burden of HCV-related liver disease in this group is increasing, but treatment uptake among PWID remains low. Among PWID, there are a number of barriers to care that should be considered and systematically addressed, but these barriers should not exclude PWID from HCV treatment. Furthermore, it has been clearly demonstrated that HCV treatment is safe and effective across a broad range of multidisciplinary healthcare settings. Given the burden of HCV-related disease among PWID, strategies to enhance HCV assessment and treatment in this group are urgently needed. These recommendations demonstrate that treatment among PWID is feasible and provides a framework for HCV assessment, management, and treatment. Further research is needed to evaluate strategies to enhance assessment, adherence, and SVR among PWID, particularly as new treatments for HCV infection become available.

Stress, Coping, and Physical Health in Caregiving.

Informal caregivers experience a great deal of stress due to care-related duties and responsibilities. Caregiving stress has the ability to impact caregivers' physical health, but has been largely understudied in caregivers of children with a chronic illness. In this study, we examine the associations of stress to both caregiver self-rated health and biomarkers of the hypothalamic-pituitary-adrenal (HPA) axis and immune systems (arginine vasopressin, c-reactive protein, tumor necrosis factor alpha). We also examine whether coping style (proactive, avoidant, support coping) buffers the links of stress to health across two different stressor contexts: caregiving for a child with a rare or undiagnosed disease (n = 101) and caregiving for a typically developing child (n = 69). Results indicated perceived stress was linked to worse self-rated health, however, stress was only linked to biological markers of health for caregivers of typically developing children. Results also suggest that coping style may moderate some of the links of stress to health, as proactive coping was linked to lower arginine vasopressin. However, models also suggested the role of coping style may differ based on caregiving context, as support coping was linked to better health only for caregivers of typically developing children, and more proactive coping overall was observed in the rare disease context. Future research should continue to examine how stress and coping interact within different caregiving contexts to protect caregiver health and well-being.

HIV coinfection with hepatitis C virus: evolving epidemiology and treatment paradigms.

Chronic hepatitis C virus (HCV) infection has become a major threat to the survival of human immunodeficiency virus (HIV)-infected persons in areas where antiretroviral therapy is available. In coinfection, viral eradication has been difficult to attain, and HCV therapy is underused. Novel therapies may be particularly beneficial for this population, yet studies lag behind those for HCV monoinfection. Increasingly, incident HCV among HIV-infected men who have sex with men is associated with sexual risk behavior further research should be performed to refine understanding of the causal mechanism of this association. The phenomenon of aggressive hepatic fibrogenesis when HIV infection precedes HCV acquisition requires longer-term observation to ensure optimal timing of HCV therapy. Medical management in coinfection will be improved by enhancing HCV detection, with annual serologic testing, screening with HCV RNA to detect acute infection, and HIV testing of HCV-infected individuals; by addressing HCV earlier in coinfected persons; and by universal consideration for HCV therapy. HCV drug trials in individuals coinfected with HIV should be expedited. HIV/HCV coinfection remains a growing and evolving epidemic; new developments in therapeutics and improved care models offer promise.

Global hepatitis C elimination: an investment framework.

WHO has set global targets for the elimination of hepatitis B and hepatitis C as a public health threat by 2030. However, investment in elimination programmes remains low. To help drive political commitment and catalyse domestic and international financing, we have developed a global investment framework for the elimination of hepatitis B and hepatitis C. The global investment framework presented in this Health Policy paper outlines national and international activities that will enable reductions in hepatitis C incidence and mortality, and identifies potential sources of funding and tools to help countries build the economic case for investing in national elimination activities. The goal of this framework is to provide a way for countries, particularly those with minimal resources, to gain the substantial economic benefit and cost savings that come from investing in hepatitis C elimination.
