Project description:BackgroundHepatitis C virus (HCV)-infected patients require a specific continuum of care (CoC) from HCV screening to treatment. We assessed CoC of HCV-infected patients in a longitudinal study.MethodsWe established a cohort of subjects undergoing HCV screening (high alanine aminotransferase levels or risk factors) during preventive consultations at a French regional medical center from 1993 to 2013. Patients were considered to be HCV-infected if HCV RNA was detected in their serum. CoC was assessed as described by Viner et al. (Hepatology 2015): Stage 1, HCV screening; Stage 2, HCV RNA testing; Stage 3, continuing care; Stage 4, antiviral treatment. Cox multivariate analysis was performed to identify factors favoring CoC, defined as at least one course of antiviral treatment.ResultsIn total, 12,993 HCV tests were performed and 478 outpatients were found to be HCV-seropositive. We included 417 seropositive patients, after excluding false positives and patients lost to follow-up. The baseline characteristics of the patients were: sex ratio (M/F) 1.4; mean age 38.5 years; intravenous drug use (IDU) in 55%; and 28% in unstable social situations, estimated by the EPICES deprivation score. Antiviral treatment was initiated for 179 (42.9%) of the 379 (90.9%) patients attending specialist consultations. CoC was associated with screening after 1997 (HR 2.0, 95%CI 1.4-2.9), age > 45 years (HR 1.5, 95%CI 1.02-2.3), patient acceptance of care (HR 9.3, 95%CI 5.4-16.10), specialist motivation for treatment (HR 10.9, 95%CI 7.4-16.0), and absence of cancer (HR 6.7, 95%CI 1.6-27.9). Other comorbid conditions, such as depression and IDU, were not associated with CoC.ConclusionsOur 20-year cohort study reveals the real-life continuum of care for HCV-infected patients in France. The number of patients involved in HCV care after positive testing was substantial due to the organization of healthcare in France. An improved CoC along with new direct-acting antivirals should help to decrease chronic HCV infection.

Project description:Hepatitis C virus (HCV) infection is a leading cause of liver-related morbidity and mortality, and more than 2 million adults in the United States are estimated to be currently infected. Reducing HCV burden will require an understanding of demographic disparities and targeted efforts to reduce prevalence in populations with disproportionate disease rates. We modeled state-level estimates of hepatitis C prevalence among U.S. adults by sex, birth cohort, and race during 2013-2016. National Health and Nutrition Examination Survey data were used in combination with state-level HCV-related and narcotic overdose-related mortality data from the National Vital Statistics System and estimates from external literature review on populations not sampled in the National Health and Nutrition Examination Survey. Nationally, estimated hepatitis C prevalence was 1.3% among males and 0.6% among females (prevalence ratio [PR] = 2.3). Among persons born during 1945 to 1969, prevalence was 1.6% compared with 0.5% among persons born after 1969 (PR = 3.2). Among persons born during 1945 to 1969, prevalence ranged from 0.7% in North Dakota to 3.6% in Oklahoma and 6.8% in the District of Columbia. Among persons born after 1969, prevalence was more than twice as high in Kentucky, New Mexico, Oklahoma, and West Virginia compared with the national average. Hepatitis C prevalence was 1.8% among non-Hispanic black persons and 0.8% among persons of other races (PR = 2.2), and the magnitude of this disparity varied widely across jurisdictions (PR range: 1.3-7.8). Overall, 23% of prevalent HCV infections occurred among non-Hispanic black persons, whereas 12% of the population was represented by this racial group. These estimates provide information on prevalent HCV infections that jurisdictions can use for understanding and monitoring local disease patterns and racial disparities in burden of disease.

Project description:All subjects were recruited at Centennial Women?s Hospital and the Perinatal Research Center in Nashville, TN beginning in 2003. Pregnant women were enrolled during their first clinical visit after obtaining informed consent as described previously. Demographic and clinical data specific to the fetus was collected from clinical records. Gestational age of the neonate was determined by maternal reporting of the last menstrual period and corroboration by ultrasound dating. Accurate knowledge of gestational age (GA) is essential for proper monitoring and care of neonates. However, accurate GA measures are often not available. DNA methylation has previously been shown to associate with GA, and has been used to accurately predict chronological age in adults. In the current study, we examine whether DNA methylation in cord blood can be used to predict gestational age at birth. Results: We found that GA can be accurately predicted from DNA methylation of neonatal cord blood and blood spot samples (DNAm GA), using 148 CpG sites selected through elastic net regression in six training datasets (N=207). We evaluated predictive accuracy in six testing datasets (N=1,202), and found that the accuracy of DNAm GA meets or exceeds accuracy of gestational age estimates based on established methods. We also found an increased DNAm GA, relative to clinical GA, was associated with increased birthweight percentile (p=.00057), adjusting for GA, sex, and ancestry, suggesting that DNAm GA could represent developmental age more accurately than clinical estimates of GA. Conclusions: Further development of this predictor could provide a method of accurate neonatal estimation of GA for use in resource-limited populations, or in cases where GA cannot be estimated clinically. When clinical estimates are available, the predictor can be used to test hypotheses related to developmental age and other early life circumstances, and may provide increased accuracy beyond clinical estimates.

Project description:Objective:To determine the prevalence of and risk factors for advanced fibrosis in patients born from 1945 through 1965 (birth cohort) who underwent testing for hepatitis C virus (HCV). Patients and Methods:Data were extracted from the electronic health record of all patients receiving primary care at a single academic institution who underwent HCV testing between September 8, 2010, and March 5, 2018. The birth cohort patients were the primary focus of the study. Fibrosis 4 (FIB-4) and aspartate aminotransferase to platelet ratio index (APRI) scores were calculated to screen for fibrosis. Results:During the study period, 7097 birth cohort patients had HCV antibody testing, 3462 (48.8%) of whom were men, 6435 (91.0%) were white, 1028 (14.5%) had diabetes mellitus, 2,034 (36.5%) had an alanine aminotransferase (ALT) level greater than 30 U/L, and 2,396 (34.2%) had body mass index of 30 kg/m2 or greater. Hepatitis C virus antibody was present in 124 (1.7%), 33 (26.6%) of whom had HCV viremia. Estimated prevalence of METAVIR [Meta-analysis of Histological Data in Viral Hepatitis] stage 4 fibrosis was 4.1% (180 of 4433) by a FIB-4 score of 3.25 or greater and 4.3% (204 of 4763) by an APRI score greater than 1.0. The odds ratio (OR) for fibrosis, determined by APRI, was significant for HCV RNA positivity (OR, 15.98; 95% CI, 7.23-35.32; P<.001), diabetes mellitus (OR, 1.98; 95% CI, 1.40-2.79; P<.001), and ALT value greater than 30 U/L (OR, 15.07 U/L; 95% CI, 9.27-24.52 U/L; P<.001) but not for body mass index of 30 kg/m2 or greater (OR, 0.77; 95% CI, 0.56-1.06; P=.11). Conclusion:Hepatitis C virus viremia, diabetes mellitus, and elevated ALT levels were associated with increased odds for development of fibrosis. In addition to HCV testing, diabetes mellitus and elevated ALT level are potential parameters to use for recommending noninvasive testing for fibrosis.

Project description:In the United States, hepatitis C virus (HCV) infection is most prevalent among adults born from 1945 through 1965, and approximately 50% to 75% of infected adults are unaware of their infection.To estimate the cost-effectiveness of birth-cohort screening.Cost-effectiveness simulation.National Health and Nutrition Examination Survey, U.S. Census, Medicare reimbursement schedule, and published sources.Adults born from 1945 through 1965 with 1 or more visits to a primary care provider annually.Lifetime.Societal, health care.One-time antibody test of 1945-1965 birth cohort.Numbers of cases that were identified and treated and that achieved a sustained viral response; liver disease and death from HCV; medical and productivity costs; quality-adjusted life-years (QALYs); incremental cost-effectiveness ratio (ICER).Compared with the status quo, birth-cohort screening identified 808,580 additional cases of chronic HCV infection at a screening cost of $2874 per case identified. Assuming that birth-cohort screening was followed by pegylated interferon and ribavirin (PEG-IFN+R) for treated patients, screening increased QALYs by 348,800 and costs by $5.5 billion, for an ICER of $15,700 per QALY gained. Assuming that birth-cohort screening was followed by direct-acting antiviral plus PEG-IFN+R treatment for treated patients, screening increased QALYs by 532,200 and costs by $19.0 billion, for an ICER of $35,700 per QALY saved.The ICER of birth-cohort screening was most sensitive to sustained viral response of antiviral therapy, the cost of therapy, the discount rate, and the QALY losses assigned to disease states.Empirical data on screening and direct-acting antiviral treatment in real-world clinical settings are scarce.Birth-cohort screening for HCV in primary care settings was cost-effective.Division of Viral Hepatitis, Centers for Disease Control and Prevention.

Project description:ContextBirth cohort ("baby boomer") screening represents a well-validated strategy for the identification of asymptomatic hepatitis C-infected patients. However, successful linkage of newly diagnosed patients to antiviral therapy has been more difficult to accomplish.ObjectiveTo analyze the results of a systemwide birth cohort screening program in a US community health care system.DesignWe analyzed the data from an ongoing hepatitis C virus (HCV) screening and treatment program that was established at NorthShore University Health System in 2015. Hepatitis C virus screening by primary care providers was prompted through automated Best Practice and Health Maintenance alerts. Patient visits and screening orders were tracked using a customized HCV dashboard. Virologic, demographic, and treatment data were assessed and compared with those of a cohort of patients with previously established HCV infection.ResultsSince program inception, 61 8161 (64.3%) of the entire NorthShore baby boomer population of 96 001 patients have completed HCV antibody testing, and 160 patients (0.26%) were antibody positive. Of 152 antibody-positive patients who underwent HCV RNA testing, 53 (34.2%) were viremic. A total of 39 of 53 patients (73.6%) underwent antiviral therapy and achieved a sustained virologic response. Compared with patients identified through screening, a comparison cohort of patients with previously established HCV had more advanced fibrosis and significantly lower dropout rates. The COVID-19 pandemic was associated with a decrease in the number of outpatient visits of screening-eligible patients and with a reduction in HCV screening rates.ConclusionOur data demonstrate the electronic medical records-assisted systemwide implementation of HCV birth cohort screening and successful linkage to antiviral therapy in a community-based US multihospital system.

Project description:BACKGROUND:In 2014, the Department of Veterans Affairs (VA) adopted a screening test policy for hepatitis C virus (HCV) in all "Baby Boomers" - those born between 1945 and 1965. About 1 in 12 Veterans were estimated to be infected with HCV yet approximately 34% of the birth cohort remained untested. Early HCV diagnosis and successful antiviral treatment decrease the risk of onward transmission, cirrhosis, hepatocellular carcinoma, liver transplant, and death. Implementing evidence-based HCV screening in primary care has great potential to reduce morbidity and mortality. To inform design and implementation of a quality improvement intervention, we studied primary care provider (PCP) perceptions of and experiences with HCV birth cohort testing. METHODS:We conducted a formative evaluation using qualitative semi-structured interviews guided by the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework. Twenty-two PCPs in six states across a large integrated US healthcare system were interviewed. Content analysis with a priori and emergent codes was performed on verbatim interview transcripts. RESULTS:We identified three themes related to primary care provider HCV testing and linkage practices, as mapped to i-PARIHS constructs: 1) evaluating cues to HCV testing (innovation/evidence), 2) framing HCV testing decisions (recipients), and 3) HCV testing and linkage to care in the new treatment era (context). The most frequently reported HCV testing cue was an electronic clinical reminder alert, followed by clinical markers and the presence of behavioral risk factors. Most PCPs saw testing as routine, but less urgent, leading to some reluctance. Providers largely saw themselves as performing guideline-concordant testing, yet no performance data were available to assess performance. Given the recent availability of new HCV medications, many PCPs were highly motivated to test and link patients to specialty care for treatment. CONCLUSIONS:Our results suggest a multi-component intervention around awareness and education, feedback of performance data, clinical reminder updates, and leadership support, would address both a significant need, and be deemed acceptable and feasible to primary care providers.

Project description:BackgroundHepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma (HCC). Asian Americans have the highest incidence and mortality rates of HCC among all US racial/ethnic groups. Inadequate monitoring and treatment of chronic hepatitis B contribute to poor health outcomes and increased healthcare costs among Asian Americans.AimsThe goal of this study is to assess the effect of a patient-led strategy on chronic hepatitis B monitoring and treatment adherence specifically among Asian Americans with culturally tailored Patient Navigator-led Intervention.MethodsFrom 2015 to 2018, 532 eligible participants living with chronic hepatitis B in the greater Philadelphia and New York city metropolitan areas were randomly assigned to either the intervention group or the control group. Generalized linear mixed-effects models were used to estimate the odds ratio (OR) for rates of doctor visits for chronic hepatitis B and rates of alanine aminotransferase testing for evidence of liver damage.ResultsIntervention group had higher rates of doctor visits than the control group at both 6-month (77.22% vs. 45.75%) and 12-month assessments (90.73% vs. 60.61%). Significantly more intervention group participants received ALT testing than control group participants at 6-month (52.90% vs. 25.10%) and 12-month (75.40% vs. 46.75%) follow-up.ConclusionsCulturally and linguistically appropriate intervention has strong effects on adherence to follow-up care among Asian American hepatitis B patients experiencing challenges to medication adherence and follow up care. These findings further identify opportunities for practical implementation of evidence-based intervention that could lead to reductions in disparities in chronic liver disease and liver cancer among high-risk, underserved populations.

Project description:A recent international workshop, organized by the authors, analyzed the obstacles facing the ambitious goal of eliminating viral hepatitis globally. We identified several policy areas critical to reaching elimination targets. These include providing hepatitis B birth-dose vaccination to all infants within 24 hours of birth, preventing the transmission of blood-borne viruses through the expansion of national hemovigilance schemes, implementing the lessons learned from the HIV epidemic regarding safe medical practices to eliminate iatrogenic infection, adopting point-of-care testing to improve coverage of diagnosis, and providing free or affordable hepatitis C treatment to all. We introduce Egypt as a case study for rapid testing and treatment scale-up: this country offers valuable insights to policy makers internationally, not only regarding how hepatitis C interventions can be expeditiously scaled-up, but also as a guide for how to tackle the problems encountered with such ambitious testing and treatment programs.
