Hepatitis B virus (HBV) screening, linkage and retention-in-care in inclusion health populations: Evaluation of an outreach screening programme in London.

OBJECTIVES: We evaluated a hepatitis B virus (HBV) screening programme, delivered by a specialist pan-London multidisciplinary outreach team, to understand population characteristics and care cascade among people who experience extreme social exclusion (Inclusion Health (IH) groups). METHODS: Point-of-care HBV screening was performed in temporary accommodation for people experiencing homelessness (PEH) and people seeking asylum (initial accommodation centres, IACs) via a mobile unit staffed by peers with lived experience, nurses, and doctors. We analysed demographics and HBV characteristics of adults screened between May 2020 and January 2022. We ascertained linkage-to-care (LTC), retention-in-care (RIC) and loss-to-follow-up (LTFU). People LTFU were contacted by peers to re-engage in care. RESULTS: 2473 people were screened: 809 in IACs, 1664 in other temporary accommodation. Overall hepatitis B surface antigen (HBsAg) prevalence was 1.7% (43/2473), highest in IACs (3.5%, 28/809). LTC within 3 months was 56% (24/43) and RIC, 87% (26/30). LTC was higher when referred to a local IH-specialist hepatitis service, compared to other services (77%, 17/22 vs 33%, 7/21; p = 0.006). LTFU was 30% (13/43), reduced to 21% (9/43) after intervention by peers. CONCLUSION: Our findings support outreach screening among IH populations and peer-supported linkage to IH-specialist hepatitis services. We recommend increased HBV testing and HBV-specific IH specialist services.

The forgotten people: Hepatitis B virus (HBV) infection as a priority for the inclusion health agenda.

Hepatitis B virus (HBV) infection represents a significant global health threat, accounting for 300 million chronic infections and up to 1 million deaths each year. HBV disproportionately affects people who are under-served by health systems due to social exclusion, and can further amplify inequities through its impact on physical and mental health, relationship with stigma and discrimination, and economic costs. The 'inclusion health' agenda focuses on excluded and vulnerable populations, who often experience barriers to accessing healthcare, and are under-represented by research, resources, interventions, advocacy, and policy. In this article, we assimilate evidence to establish HBV on the inclusion health agenda, and consider how this view can inform provision of better approaches to diagnosis, treatment, and prevention. We suggest approaches to redress the unmet need for HBV interventions among excluded populations as an imperative to progress the global goal for the elimination of viral hepatitis as a public health threat.

"It's too hard" - the management of latent TB in under-served populations in the UK: a qualitative study.

BACKGROUND: UK national guidance recommends systematic screening for latent tuberculosis infection (LTBI) in under-served populations, including people experiencing homelessness and people who use drugs. This is not routinely implemented in the UK, and the reasons for this policy-practice mismatch remain underexplored. METHODS: Semi-structured qualitative interviews were conducted with 19 healthcare professionals from across the UK. Participants were recruited using purposive sampling and snowballing, identifying individuals with excellent knowledge of their regions practice and policy of LTBI management. The interviews were conducted online, and were audio recorded, with transcripts thematically analysed using a two-stage inductive coding process to explore perceived barriers and enablers to LTBI screening. RESULTS: Most participants had previous experience managing LTBI in under-served populations, but none were conducting systematic screening as per national guidance. We identified service provision challenges and low prioritisation of LTBI as the key explanatory themes driving this policy-practice mismatch. Lack of resource, and the complexity of clinical decision making were two key service level barriers. System and service inertia, and lack of cost effectiveness evidence led to LTBI being deprioritised. Service integration and promotion of WHO targets for TB elimination were highlighted as potential solutions. CONCLUSION: Integrating LTBI testing and treatment with existing health services for under-served populations could improve feasibility and efficacy. Promotion of UK TB elimination goals and generation of regional evidence to support commissioning for LTBI care is vital. Without such a multi-pronged approach inertia is likely to persist and the zeitgeist will remain: "it's too hard".

Tuberculosis Surveillance in Romania Among Vulnerable Risk Groups Between 2015 and 2017.

Purpose: Romania has the highest tuberculosis (TB) burden in the European Union/European Economic Area (EU/EEA) comprising almost a quarter (23.4%) of the reported patients in 2017, and a TB notification rate six times higher than the EU/EEA average. Although the overall TB notification rate in Romania declined from 154/100.000 individuals to 66/100.000 individuals in the general population between 2002 and 2017, TB notification rates remain high in certain vulnerable populations groups such as prisoners, the homeless population and among drug users. Patients and Methods: We conducted a descriptive study regarding TB monitoring data in Romania, including the aforementioned TB risk groups. Results: Analysis regarding notified TB cases among these risk groups indicates that TB rates are 7 to 18 times higher than in the general population. One of the most alarming aspects regards the exceedingly high proportion of HIV-seropositivity among drug users and the high mortality rates among the homeless population and among drug users with TB. Conclusion: This data underlines the importance of early identification among social risk groups using outreach active case-finding (ACF) activities, possibly combining TB screening with screening for other common, possibly life-threatening, co-morbidities for which an effective treatment is available. ACF could have a decisive role in TB control and eradication in Romania, when aimed at these high-risk groups.

Use of targeted mobile X-ray screening and computer-aided detection software to identify tuberculosis among high-risk groups in Romania: descriptive results of the E-DETECT TB active case-finding project.

OBJECTIVE: To implement and assess the mobile X-ray unit (MXU) equipped with digital radiography, computer-aided detection (CAD) software and molecular point of care tests to improve early tuberculosis (TB) diagnosis in vulnerable populations in a TB outreach screening programme in Romania. DESIGN: Descriptive study. SETTINGS: Prisons in Bucharest and other cities in the southern part of Romania, homeless shelters and services for problem drug users in Bucharest, and Roma populations in Bucharest and Craiova. PARTICIPANTS: 5510 individuals attended the MXU service; 5003 persons were radiologically screened, 61% prisoners, 15% prison staff, 11% Roma population, 10% homeless persons and/or problem drug users and 3% other. INTERVENTIONS: Radiological digital chest X-ray (CXR) screening of people at risk for TB, followed by CAD and human reading of the CXRs, and further TB diagnostics when the pulmonologist classified the CXR as suggestive for TB. PRIMARY AND SECONDARY OUTCOME MEASURES: Ten bacteriologically confirmed TB cases were identified translating into an overall yield of 200 per 100 000 persons screened (95% CIs of 109 to 368 per 100 000). Prevalence rates among homeless persons and/or problem drug users (826/100 000; 95% CI 326 to 2105/100 000) and the Roma population (345/100 000; 95% CI 95 to 1251/100 000) were particularly high. RESULTS: The human reader classified 6.4% (n=317) of the CXRs as suspect for TB (of which 32 were highly suggestive for TB); 16.3% of all CXRs had a CAD4TB version 6 score >50. All 10 diagnosed TB patients had a CAD4TB score >50; 9 had a CAD4TB score >60. CONCLUSIONS: Given the high TB prevalence rates found among homeless persons and problem drug users and in the Roma population, targeted active case finding has the potential to deliver a major contribution to TB control in Romania.

Peer advocacy and access to healthcare for people who are homeless in London, UK: a mixed method impact, economic and process evaluation protocol.

INTRODUCTION: People who are homeless experience higher morbidity and mortality than the general population. These outcomes are exacerbated by inequitable access to healthcare. Emerging evidence suggests a role for peer advocates-that is, trained volunteers with lived experience-to support people who are homeless to access healthcare. METHODS AND ANALYSIS: We plan to conduct a mixed methods evaluation to assess the effects (qualitative, cohort and economic studies); processes and contexts (qualitative study); fidelity; and acceptability and reach (process study) of Peer Advocacy on people who are homeless and on peers themselves in London, UK. People with lived experience of homelessness are partners in the design, execution, analysis and dissemination of the evaluation. ETHICS AND DISSEMINATION: Ethics approval for all study designs has been granted by the National Health Service London-Dulwich Research Ethics Committee (UK) and the London School of Hygiene and Tropical Medicine's Ethics Committee (UK). We plan to disseminate study progress and outputs via a website, conference presentations, community meetings and peer-reviewed journal articles.

Health of people experiencing co-occurring homelessness, imprisonment, substance use, sex work and/or severe mental illness in high-income countries: a systematic review and meta-analysis.

BACKGROUND: People affected by homelessness, imprisonment, substance use, sex work or severe mental illness experience substantial excess ill health and premature death. Though these experiences often co-occur, health outcomes associated with their overlap have not previously been reviewed. We synthesised existing evidence on mortality, morbidity, self-rated health and quality of life among people affected by more than one of these experiences. METHODS: In this systematic review and meta-analysis, we searched Medline, Embase, and PsycINFO for peer-reviewed English-language observational studies from high-income countries published between 1 January 1998 and 11 June 2018. Two authors undertook independent screening, with risk of bias assessed using a modified Newcastle-Ottawa Scale. Findings were summarised by narrative synthesis and random-effect meta-analysis. RESULTS: From 15 976 citations, 2517 studies underwent full-text screening, and 444 were included. The most common exposure combinations were imprisonment/substance use (31% of data points) and severe mental illness/substance use (27%); only 1% reported outcomes associated with more than two exposures. Infections were the most common outcomes studied, with blood-borne viruses accounting for 31% of all data points. Multiple exposures were associated with poorer outcomes in 80% of data points included (sign test for effect direction, p<0.001). Meta-analysis suggested increased all-cause mortality among people with multiple versus fewer exposures (HR: 1.57 and 95% CI: 1.38 to 1.77), though heterogeneity was high. CONCLUSION: People affected by multiple exclusionary processes experience profound health inequalities, though there are important gaps in the research landscape. Addressing the health needs of these populations is likely to require co-ordinated action across multiple sectors, such as healthcare, criminal justice, drug treatment, housing and social security.

Exploring and understanding HCV patient journeys- HEPCARE Europe project.

BACKGROUND: Hepatitis C Virus (HCV) is a leading cause for chronic liver diseases worldwide. The European Union and World Health Organization aspire to eliminate HCV by 2030. However, among at-risk populations, including, homeless people, prisoners and People Who Inject Drugs, access to diagnosis and treatment is challenging. Hepcare Europe is an integrated model of care developed to address this by assessing potential reasons for these restrictions and determining measures needed to improve HCV diagnosis, treatment and access to care within different communities. OBJECTIVES: HepCare Europe is an EU-supported project involving collaboration between five institutions in: Ireland, United Kingdom, Spain and Romania. We aim to explore the journey of care experienced by those living with HCV with a focus on previous care disruptions (loss to follow up) and the new HepCare Europe Programme. METHODS: Research teams conducted semi-structured interviews with patients who accessed services through HepCare Europe thus, patients were recruited by purposeful sampling. Patients interviewed had received, or were in the final weeks of receiving, treatment. The interviews were audio recorded, transcribed and translated into English, and sent to the Dublin team for inductive thematic analysis. Researchers from the HepCare Europe research team coded the data separately, then together. RESULTS: Common themes are introduced to present similarities, following individual site themes to highlight the importance of tailored interventions for each country. Key themes are: 1) Hepatitis C patients lost to follow up 2) HepCare improved access to treatment and 3) the need for improved HCV education. Individual themes also emerged for each site. These are: Ireland: New opportunities associated with achieving Sustained Virologic Responses (SVR). Romania: HCV is comparatively less crucial in light of Human Immunodeficiency Viruses (HIV) coinfections. UK: Patients desire support to overcome social barriers and Spain: Improved awareness of HCV, treatment and alcohol use. CONCLUSION: This study identified how the tailored HepCare interventions enabled improved HCV testing and linkage to care outcomes for these patients. Tailored interventions that targeted the needs of patients, increased the acceptability and success of treatment by patients. HepCare demonstrated the need for flexibility in treatment delivery, and provided additional supports to keep patients engaged and educated on new treatment therapies.

Hospital readmission among people experiencing homelessness in England: a cohort study of 2772 matched homeless and housed inpatients.

BACKGROUND: Inpatients experiencing homelessness are often discharged to unstable accommodation or the street, which may increase the risk of readmission. METHODS: We conducted a cohort study of 2772 homeless patients discharged after an emergency admission at 78 hospitals across England between November 2013 and November 2016. For each individual, we selected a housed patient who lived in a socioeconomically deprived area, matched on age, sex, hospital, and year of discharge. Counts of emergency readmissions, planned readmissions, and Accident and Emergency (A&E) visits post-discharge were derived from national hospital databases, with a median of 2.8 years of follow-up. We estimated the cumulative incidence of readmission over 12 months, and used negative binomial regression to estimate rate ratios. RESULTS: After adjusting for health measured at the index admission, homeless patients had 2.49 (95% CI 2.29 to 2.70) times the rate of emergency readmission, 0.60 (95% CI 0.53 to 0.68) times the rate of planned readmission and 2.57 (95% CI 2.41 to 2.73) times the rate of A&E visits compared with housed patients. The 12-month risk of emergency readmission was higher for homeless patients (61%, 95% CI 59% to 64%) than housed patients (33%, 95% CI 30% to 36%); and the risk of planned readmission was lower for homeless patients (17%, 95% CI 14% to 19%) than for housed patients (30%, 95% CI 28% to 32%). While the risk of emergency readmission varied with the reason for admission for housed patients, for example being higher for admissions due to cancers than for those due to accidents, the risk was high across all causes for homeless patients. CONCLUSIONS: Hospital patients experiencing homelessness have high rates of emergency readmission that are not explained by health. This highlights the need for discharge arrangements that address their health, housing and social care needs.

Practising critical resilience as an advanced peer support worker in London: A qualitative evaluation of a peer-led hepatitis C intervention amongst people experiencing homelessness who inject drugs.

BACKGROUND: Peer support has been used as a mechanism to facilitate active engagement with healthcare amongst underserved populations. The HepCare project upskilled experienced peer support workers (PSWs) to become equal members of a service provider team, taking on advanced clinical roles normally carried out by medical or nursing specialists. METHOD: A participatory case study approach was taken to the study following the methodological guidance of Merriam (1998). The subject of the case in our study is the advanced peer support workers (APSWs) functioning in the HepCare project as service providers. The object of the case is an exploration of their transition to service provider in the HCV screening and treatment support service. Five peer led in-depth interviews with APSWs were supplemented by a survey of health professionals, interviews with service users, documentary evidence in the form of job descriptions, observational notes and a blog from the field. Thematic analysis of the data was conducted, refined and finalised in a workshop with the research team and APSW participants. RESULTS: Three themes were generated from the data that explore the peer support worker's transition to APSW in the programme: Transition to Integration, Retaining 'Peerness', and Practising Critical Resilience. The advocacy and support enacted by the APSWs through the HepCare project, offer purpose and meaning alongside integration into a new social group. This is buffered by the supportive context of the programme and facilitates a motivating sense of worth. CONCLUSION: The programme offers policy guidance for the structured career development of APSWs and a platform for enactment of critical resilience as they transition to their advanced role, in the healthcare provider team.

Prevalence, incidence, and outcomes across cardiovascular diseases in homeless individuals using national linked electronic health records.

AIMS: The risk and burden of cardiovascular disease (CVD) are higher in homeless than in housed individuals but population-based analyses are lacking. The aim of this study was to investigate prevalence, incidence and outcomes across a range of specific CVDs among homeless individuals. METHODS AND RESULTS: Using linked UK primary care electronic health records (EHRs) and validated phenotypes, we identified homeless individuals aged ≥16 years between 1998 and 2019, and age- and sex-matched housed controls in a 1:5 ratio. For 12 CVDs (stable angina; unstable angina; myocardial infarction; sudden cardiac death or cardiac arrest; unheralded coronary death; heart failure; transient ischaemic attack; ischaemic stroke; subarachnoid haemorrhage; intracerebral haemorrhage; peripheral arterial disease; abdominal aortic aneurysm), we estimated prevalence, incidence, and 1-year mortality post-diagnosis, comparing homeless and housed groups. We identified 8492 homeless individuals (32 134 matched housed individuals). Comorbidities and risk factors were more prevalent in homeless people, e.g. smoking: 78.1% vs. 48.3% and atrial fibrillation: 9.9% vs. 8.6%, P < 0.001. CVD prevalence (11.6% vs. 6.5%), incidence (14.7 vs. 8.1 per 1000 person-years), and 1-year mortality risk [adjusted hazard ratio 1.64, 95% confidence interval (CI) 1.29-2.08, P < 0.001] were higher, and onset was earlier (difference 4.6, 95% CI 2.8-6.3 years, P < 0.001), in homeless, compared with housed people. Homeless individuals had higher CVD incidence in all three arterial territories than housed people. CONCLUSION: CVD in homeless individuals has high prevalence, incidence, and 1-year mortality risk post-diagnosis with earlier onset, and high burden of risk factors. Inclusion health and social care strategies should reflect this high preventable and treatable burden, which is increasingly important in the current COVID-19 context.

COVID-19 among people experiencing homelessness in England: a modelling study.

BACKGROUND: People experiencing homelessness are vulnerable to COVID-19 due to the risk of transmission in shared accommodation and the high prevalence of comorbidities. In England, as in some other countries, preventive policies have been implemented to protect this population. We aimed to estimate the avoided deaths and health-care use among people experiencing homelessness during the so-called first wave of COVID-19 in England-ie, the peak of infections occurring between February and May, 2020-and the potential impact of COVID-19 on this population in the future. METHODS: We used a discrete-time Markov chain model of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that included compartments for susceptible, exposed, infectious, and removed individuals, to explore the impact of the pandemic on 46 565 individuals experiencing homelessness: 35 817 living in 1065 hostels for homeless people, 3616 sleeping in 143 night shelters, and 7132 sleeping outside. We ran the model under scenarios varying the incidence of infection in the general population and the availability of prevention measures: specialist hotel accommodation, infection control in homeless settings, and mixing with the general population. We divided our scenarios into first wave scenarios (covering Feb 1-May 31, 2020) and future scenarios (covering June 1, 2020-Jan 31, 2021). For each scenario, we ran the model 200 times and reported the median and 95% prediction interval (2·5% and 97·5% quantiles) of the total number of cases, the number of deaths, the number hospital admissions, and the number of intensive care unit (ICU) admissions. FINDINGS: Up to May 31, 2020, we calibrated the model to 4% of the homeless population acquiring SARS-CoV-2, and estimated that 24 deaths (95% prediction interval 16-34) occurred. In this first wave of SARS-CoV-2 infections in England, we estimated that the preventive measures imposed might have avoided 21 092 infections (19 777-22 147), 266 deaths (226-301), 1164 hospital admissions (1079-1254), and 338 ICU admissions (305-374) among the homeless population. If preventive measures are continued, we projected a small number of additional cases between June 1, 2020, and Jan 31, 2021, with 1754 infections (1543-1960), 31 deaths (21-45), 122 hospital admissions (100-148), and 35 ICU admissions (23-47) with a second wave in the general population. However, if preventive measures are lifted, outbreaks in homeless settings might lead to larger numbers of infections and deaths, even with low incidence in the general population. In a scenario with no second wave and relaxed measures in homeless settings in England, we projected 12 151 infections (10 718-13 349), 184 deaths (151-217), 733 hospital admissions (635-822), and 213 ICU admissions (178-251) between June 1, 2020, and Jan 31, 2021. INTERPRETATION: Outbreaks of SARS-CoV-2 in homeless settings can lead to a high attack rate among people experiencing homelessness, even if incidence remains low in the general population. Avoidance of deaths depends on prevention of transmission within settings such as hostels and night shelters. FUNDING: National Institute for Health Research, Wellcome, and Medical Research Council.

Protocol for a systematic review of treatment adherence for HIV, hepatitis C and tuberculosis among homeless populations.

BACKGROUND: Homelessness is a global issue and HIV, hepatitis C and tuberculosis are known to be prevalent in this group. Homeless populations face significant barriers to care. We aim to summarise evidence of treatment initiation and completion for homeless populations with these infections, and their associated factors, through a systematic review and meta-analysis. METHODS: We will search MEDLINE, Embase and CINAHL for all study types and conference abstracts looking at either (1) treatment initiation in a cohort experiencing homelessness with at least one of HIV, hepatitis C, active tuberculosis and/or latent tuberculosis infection (LTBI); (2) treatment completion for those who initiated treatment. We will perform a meta-analysis of the proportion of those with each infection who initiate and complete treatment, as well as analysis of individual and health system factors that may affect adherence levels. We will evaluate the quality of research papers using the Newcastle-Ottawa scale. DISCUSSION: Given the political emphasis on global elimination of these diseases, and the current lack of understanding of effective and equitable treatment adherence strategies in homeless populations, this review will provide insight to policy-makers and service providers aiming to improve homeless healthcare. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42019153150.

HEPCARE EUROPE- A case study of a service innovation project aiming at improving the elimination of HCV in vulnerable populations in four European cities.

OBJECTIVES: Hepatitis C Virus (HCV) is a significant cause of chronic liver disease. Among at-risk populations, access to diagnosis and treatment is challenging. We describe an integrated model of care, Hepcare Europe, developed to address this challenge. METHODS: Using a case-study approach, we describe the cascade of care outcomes at all sites. Cost analyses estimated the cost per person screened and linked to care. RESULTS: A total of 2608 participants were recruited across 218 clinical sites. HCV antibody test results were obtained for 2568(98•5%); 1074(41•8%) were antibody-positive, 687(60•5%) tested positive for HCV-RNA, 650(60•5%) were linked to care, and 319(43•5%) started treatment. 196(61•4%) of treatment initiates achieved a Sustained Viral Response (SVR) at dataset closure, 108(33•9%) were still on treatment, eight (2•7%) defaulted from treatment, and seven (2•6%) had virologic failure or died. The cost per person screened varied from €194 to €635, while the cost per person linked to care varied from €364 to €2035. CONCLUSIONS: Hepcare enhanced access to HCV treatment and cure, and costs were affordable in all settings, offering a framework for scale-up and reproducibility.

Cardiovascular disease in homeless versus housed individuals: a systematic review of observational and interventional studies.

OBJECTIVES: To identify: (i) risk of cardiovascular disease (CVD) in homeless versus housed individuals and (ii) interventions for CVD in homeless populations. METHODS: We conducted a systematic literature review in EMBASE until December 2018 using a search strategy for observational and interventional studies without restriction regarding languages or countries. Meta-analyses were conducted, where appropriate and possible. Outcome measures were all-cause and CVD mortality, and morbidity. RESULTS: Our search identified 17 articles (6 case-control, 11 cohort) concerning risk of CVD and none regarding specific interventions. Nine were included to perform a meta-analysis. The majority (13/17, 76.4%) were high quality and all were based in Europe or North America, including 765 459 individuals, of whom 32 721 were homeless. 12/17 studies were pre-2011. Homeless individuals were more likely to have CVD than non-homeless individuals (pooled OR 2.96; 95% CI 2.80 to 3.13; p<0.0001; heterogeneity p<0.0001; I2=99.1%) and had increased CVD mortality (age-standardised mortality ratio range: 2.6-6.4). Compared with non-homeless individuals, hypertension was more likely in homeless people (pooled OR 1.38-1.75, p=0.0070; heterogeneity p=0.935; I2=0.0%). CONCLUSIONS: Homeless people have an approximately three times greater risk of CVD and an increased CVD mortality. However, there are no studies of specific pathways/interventions for CVD in this population. Future research should consider design and evaluation of tailored interventions or integrating CVD into existing interventions.

Premature mortality attributable to socioeconomic inequality in England between 2003 and 2018: an observational study.

BACKGROUND: Low socioeconomic position is consistently associated with increased risk of premature death. The aim of this study is to measure the aggregate scale of inequality in premature mortality for the whole population of England. METHODS: We used mortality records from the UK Office for National Statistics to study all 2 465 285 premature deaths (defined as those before age 75 years) in England between Jan 1, 2003, and Dec 31, 2018. Socioeconomic position was defined using deciles of the Index of Multiple Deprivation: a measure of neighbourhood income, employment, education levels, crime, health, availability of services, and local environment. We calculated the number of expected deaths by applying mortality in the least deprived decile to other deciles, within the strata of age, sex, and time. The mortality attributable to socioeconomic inequality was defined as the difference between the observed and expected deaths. We also used life table modelling to estimate years-of-life lost attributable to socioeconomic inequality. FINDINGS: 35·6% (95% CI 35·3-35·9) of premature deaths were attributable to socioeconomic inequality, equating to 877 082 deaths, or one every 10 min. The biggest contributors were ischaemic heart disease (152 171 excess deaths), respiratory cancers (111 083) and chronic obstructive pulmonary disease (83 593). The most unequal causes of death were tuberculosis, opioid use, HIV, psychoactive drugs use, viral hepatitis, and obesity, each with more than two-thirds attributable to inequality. Inequality was greater among men and peaked in early childhood and at age 40-49 years. The proportion of deaths attributable to inequality increased during the study period, particularly for women, because mortality rates among the most deprived women (excluding cardiovascular diseases) plateaued, and for some diseases increased. A mean of 14·4 months of life before age 75 years are lost due to socioeconomic inequality. INTERPRETATION: One in three premature deaths are attributable to socioeconomic inequality, making this our most important public health challenge. Interventions that address upstream determinants of health should be prioritised. FUNDING: National Institute of Health Research; Wellcome Trust.

HepCare Europe-A service innovation project. HepCheck: Characteristics of the patient population with active infection as defined by HCV RNA.

BACKGROUND: Hepatitis C virus (HCV) is a main cause of chronic liver disease worldwide and is consistently under-diagnosed. Community-based screening initiatives, such as HepCheck, have been identified as important components of HCV care. HepCheck focuses on screening and identifying HCV RNA-positive cases in high-risk populations and linking them to care as part of a larger European project to improve HCV care (HepCare). METHODS: HCV testing with a self-administered questionnaire was offered to 2822 individuals. RESULTS: There were 2079 patients screened. Overall, 397 (19%) of the total screened cohort were identified as having active HCV infections as measured by HCV RNA PCR. The patients were mostly male (84%), white (88%), and had a history of injecting drug use (IDU) (86%), homelessness (58%), and tattooing (42%). There were 136 new cases (7% of the total sample and 34% of identified active infections). Romania had the highest proportion of newly identified cases with 87%, then Ireland with 60%, and Spain with 43%; the UK had the lowest proportion of new cases at 10%. CONCLUSIONS: For those lost to follow-up, a major strategy is re-engagement. For those newly diagnosed, the 'seek and treat' approach is a key strategy. Thus, different priorities are defined for different countries.
