An evolutionary concept analysis: stigma among women living with hepatitis C.

BACKGROUND: Stigma is a complex social phenomenon that leads to marginalization and influences the course of illness. In the context of hepatitis C virus (HCV), stigma is a well-documented barrier to accessing care, treatment, and cure. In recent years, HCV rates among women have increased, resulting in an urgent need to address stigma and its harmful effects. The purpose of this concept analysis was to investigate stigma in the context of women living with HCV using Rodgers' evolutionary method. METHODS: PubMed, CINAHL, Scopus, Medline, PsycINFO, and Nursing and Allied Health were used to identify articles describing HCV stigma among women. Articles from peer-reviewed journals and geographic locations, published between 2002-2023, were included in the analysis. As specified in Rodgers' evolutionary method, articles were analyzed with a focus on the concept's context, surrogate and related terms, antecedents, attributes, examples, and consequences. RESULTS: Following screening, 33 articles were selected for inclusion in the analysis. Discrimination and marginalization were identified as surrogate and related terms to stigma; and antecedents of stigma were identified as limited knowledge, fear of diagnosis, and disclosure. Prevalent attributes of stigma in the literature were described as feelings of decreased self-worth, negative stereotyping, and fear of transmission. Importantly, HCV stigma among women is unique in comparison to other forms of infectious disease-related stigma, primarily due its impact on women's identity as mothers and caregivers. Stigmatization of women living with HCV resulted in negative consequences to personal relationships and healthcare access due to decreased health-seeking behaviours. Although access to HCV treatment has changed considerably over time, a temporal analysis could not be completed due to the limited number of articles. CONCLUSIONS: Stigma in the context of women living with HCV has its own unique antecedents, attributes, and consequences. This enhanced understanding of stigma among women living with HCV has the potential to inform improved and more effective approaches to care, which will be required to reach HCV elimination. Furthermore, this analysis identifies stigma layering and stigma in the direct-acting antiviral  treatment era as areas for more in-depth future inquiry.

Evaluation of Prenatal Hepatitis C Virus Prevalence Using Universal Screening, and Linkage to Care in a Real-World Setting in Ontario.

OBJECTIVES: International infectious disease/obstetrical societies have recently recommended universal hepatitis C virus (HCV) prenatal screening and these same recommendations are forthcoming in Canada. At present, there is no formal analysis of universal HCV screening or linkage to care of pregnant people in Ontario. The objectives of our study were to determine the seroprevalence of HCV using 2 different methods to evaluate universal screening, as well as identify opportunities that may improve linkage to care. METHODS: To assess seroprevalence in a large urban area, we aimed to test 12 000 de-identified samples submitted for prenatal HIV testing in the catchment area of Toronto Public Health for HCV antibodies. Then, to assess the seroprevalence as well as the operational impact and follow-up in a real-world setting, we completed a Quality Improvement Project (QIP) for 1 year at a large tertiary care obstetrical centre in London, Ontario. RESULTS: From 2019 to 2021, 11 999 de-identified samples were screened from Toronto with a seroprevalence of 0.40 (95% CI 0.29-0.53). In London, 5771 people were screened in 2021 with a seroprevalence of 0.55% (95% CI 0.38-0.78). Taken together, those aged 26-35 years had the highest positivity; in the QIP, 9% had no documented risk factor, and 59% of individuals were not linked to the next step in HCV care. CONCLUSIONS: HCV prenatal seroprevalence in Ontario is comparable to hepatitis B virus, and ∼15-30-fold higher than HIV. Diagnosis in pregnancy is critical to facilitate referrals for treatment between pregnancies and could increase screening among children born to positive women.

The impact of the first, second and third waves of covid-19 on hepatitis B and C testing in Ontario, Canada.

The COVID-19 pandemic interrupted routine healthcare services. Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are often asymptomatic, and therefore, screening and on/post-treatment monitoring are required. Our aim was to determine the effect of the first, second and third waves of the pandemic on HBV and HCV testing in Ontario, Canada. We extracted data from Public Health Ontario for HBV and HCV specimens from 1 January 2019 to 31 May 2021. Testing volumes were evaluated and stratified by age, sex and region. Changes in testing volumes were analysed by per cent and absolute change. Testing volumes decreased in April 2020 with the first wave of the pandemic and recovered to 72%-75% of prepandemic volumes by the end of the first wave. HBsAg testing decreased by 33%, 18% and 15%, and HBV DNA testing decreased by 37%, 27% and 20%, in each consecutive wave. Anti-HCV testing decreased by 35%, 21% and 19%, and HCV RNA testing decreased by 44%, 30% and 36% in each consecutive wave. These trends were consistent by age, region and sex. Prenatal HBV testing volumes were stable. In conclusion, significant decreases in HBV and HCV testing occurred during the first three waves of the pandemic and have not recovered. In addition to direct consequences on viral hepatitis elimination efforts, these data provide insight into the impacts of the pandemic on chronic disease screening and management. Strategies to make up for missed testing will be critical to avoid additional consequences of COVID-19 long after the pandemic has resolved.

Reducing Read Time of Point-of-Care Test Does Not Affect Detection of Hepatitis C Virus and Reduces Need for Reflex RNA.

BACKGROUND & AIMS: Global elimination of hepatitis C virus (HCV) will require increases in diagnosis. Point of care (POC) tests that detect antibodies against HCV can be useful for testing large and difficult to reach populations. The most accurate POC test requires a 20 min read time to identify antibody-positive samples. We investigated whether viremic patients could be identified using a shorter read time, to increase efficiency and reduce the need for reflex tests (a follow-up test for HCV RNA on the same specimen to confirm viremia). METHODS: Patients with past or current HCV infections provided samples at 2 clinics in Canada for evaluation by the OraQuick HCV Rapid antibody POC test. A community HCV-screening program in Madrid, Spain (real-world cohort) invited people to be tested for HCV with the same OraQuick test. Patients provided samples of whole blood, via finger prick. Fingerprick samples were tested immediately after collection. In the clinic cohort, photographs of the developing test were taken at 15 second intervals, and blinded readers recorded the time to positivity. In the real-world cohort, readers recorded the OraQuick result at 5 minutes, and each minute after, up to 10 minutes, and then again at 20 minutes; viremia was then evaluated using a POC HCV RNA test (GeneXpert HCV Viral Load Assay). Sera from viremic and non-viremic clinic patients were used to quantify antibody titers to investigate the relationship between the time of band appearance and antibody concentration. Fisher's exact test and exact logistic regression were used to determine factors associated with a positive result at 5 minutes. RESULTS: Blood from all viremic patients produced a positive result in the antibody POC test by 5 min. Median time to a positive result for 171 viremic patients was 2.6 min (range, 1.8-4.6 min), vs 4.1 min (range, 2.3-14.4 min) for 108 patients with resolved infection (P < .001). The 5-min threshold identified all viremic cases among 176 HCV antibody-positive patients in the real-world cohort, confirmed by testing for HCV RNA. In the pooled cohorts, antibody positivity at 5 min identified viremic patients with 100% sensitivity (95% CI, 98.4%-100%); the negative predictive value was 100% (95% CI, 94.9%-100%). The positive predictive value at 5 min was 62.0% (95% CI, 56.7%-67.0%) and therefore insufficient alone to detect viremia; an HCV RNA test would still be necessary to confirm active infection. CONCLUSIONS: The wait time for the OraQuick HCV Rapid antibody POC blood test can be reduced from 20 min to 5 min and continue to reliably identify patients with HCV infection. Shortening the test time could increase high-throughput screening, reduce loss to follow up, and reduce the need for reflex HCV RNA testing.

The emergency department as a setting-specific opportunity for population-based hepatitis C screening: An economic evaluation.

BACKGROUND AND AIMS: The World Health Organization's hepatitis C virus (HCV) elimination strategy recognizes the need for interventions that identify populations most affected by infection. The emergency department (ED) has been suggested as a setting for HCV screening. The study objective was to explore the health and economic impact of HCV screening in the ED setting. METHODS: We used a microsimulation model to conduct a cost-utility analysis evaluating two ED setting-specific strategies: no screening, and screening and subsequent treatment. Strategies were examined for two populations: (a) the general ED patient population; and (b) ED patients born between 1945 and 1975. The analysis was conducted from a healthcare payer perspective over a lifetime time horizon. A reference and high ED HCV seroprevalence measure were examined in the Canadian healthcare setting.US costs of chronic infection were used for a scenario analysis of screening in the US healthcare setting. RESULTS: For birth cohort screening, in comparison to no screening, one liver-related death was averted for every 760 and 123 persons screened for the reference and high seroprevalence measures. For general population screening, one liver-related death was averted for every 831 and 147 persons screened for the reference and high seroprevalence measures. In comparison to no screening, birth cohort screening was cost-effective at CAN$25,584/quality-adjusted life year (QALY) and US$42,615/QALY. General population screening was cost-effective at CAN$19,733/QALY and US$32,187/QALY. CONCLUSIONS: ED screening may represent a cost-effective component of population-based strategies to eliminate HCV. Further studies are warranted to explore the feasibility and acceptability of this approach.

Prenatal hepatitis B screening, and hepatitis B burden among children, in Ontario: a descriptive study.

BACKGROUND: Ontario is 1 of 5 provinces that immunize adolescents for hepatitis B virus (HBV), despite the World Health Organization recommendation for universal birth dose vaccination. One rationale for not vaccinating at birth is that universal prenatal screening and related interventions prevent vertical transmission. The aims of our study were to evaluate the uptake and epidemiology of prenatal HBV screening, and to determine the number of children in Ontario with a diagnosis of HBV before adolescent vaccination. METHODS: We extracted data from ICES, Public Health Ontario and Better Outcomes & Registry Network (BORN) Ontario databases. We assessed prenatal screening uptake and prevalence of prenatal hepatitis B surface antigen (HBsAg) from 2012 to 2016, as well as subsequent hepatitis B e-antigen (HBeAg) and HBV DNA testing and percent positivity. We used age and region to subcategorize the results. In a separate unlinked analysis, we evaluated the number of children positive for HBV aged 0-11 years who were born in Ontario from 2003 to 2013. RESULTS: From 2012 to 2016, 93% of pregnant women were screened for HBV, with an HBsAg prevalence of 0.6%. Prevalence of HBsAg increased with age, peaking at older than 45 years at 3%. North Toronto had the highest overall prevalence of 1.5%, whereas northern Ontario had the lowest. Of women who were HBsAg positive, HBeAg and HBV DNA tests were subsequently ordered in 13% and 38%, respectively. Of children born in Ontario between 2003 and 2013, 139 of 23 759 tested positive for HBV. INTERPRETATION: Prenatal HBV screening is not universal and subsequent evaluation is poor, limiting optimal intervention and possibly contributing to some Ontario-born children being given a diagnosis of HBV before age 12 years. These findings underscore the limitations of the province's adolescent vaccination strategy.

Factors associated with knowledge and awareness of Hepatitis B in individuals of Chinese descent: Results from a mass point of care testing and outreach campaign in Toronto, Canada.

Background: Migrants from hepatitis B virus (HBV) endemic regions are at high risk of having chronic infection. Despite this, HBV knowledge and awareness programming, and low-barrier screening methods such as point of care (POC) testing, among this group have yet to become routine. Methods: We conducted a mass HBV POC screening and knowledge and awareness campaign for individuals of Chinese descent in Toronto, Canada. POC screening was administered, then participants completed a knowledge questionnaire. Logistic regression identified associations between demographic factors and participants' level of HBV knowledge. Results: From 2015 to 2018, 33 outreach events resulted in 891 individuals completing testing and the knowledge questionnaire. Individuals averaged 64.4 years old. Most, 62% (N = 552), were female, and 73.6% (N = 656) have been in Canada for <30 years. The average questionnaire score was 70.7% correct, with 65.2% (N = 581) demonstrating a high level of HBV knowledge. Post-secondary education (OR: 2.19, 95% CI: 1.41, 3.39), income of $50,000 to <$75,000 (OR: 2.74, 95% CI: 1.39, 5.43), and having familial history of HBV (OR: 1.72, 95% CI: 1.06, 2.78) were associated with high knowledge. The observed prevalence of HBV was 1.5%, with 13 individuals testing positive on the POC test and confirmatory laboratory testing. Conclusions: Improving knowledge and awareness of HBV is critical to empowering people, especially migrants who experience barriers to care, to pursue vaccination, testing, and treatment. Combining knowledge outreach and POC test campaigns, enabled discussion and screening for HBV with large numbers of people, and can be tailored for optimal effectiveness for specific groups.

Increasing linkage to hepatitis C care following trauma-informed rehabilitation: An education and quality improvement project among women.

INTRODUCTION: The on-going substance use crisis has led to unprecedented rates of hepatitis C virus (HCV) in Canada, with increasing positivity among women who use drugs (WWUD). Despite efforts to reduce barriers to HCV testing and treatment, follow-up remains a major issue. METHODS: In this quality improvement project (QIP), we partnered with a short-stay trauma-informed residential drug treatment facility specifically for WWUD, to provide an engaging peer-led HCV education session, followed by low-barrier nurse and peer-led testing and treatment. We sought to evaluate these interventions, as well as determine what factors could improve engagement after women leave. RESULTS: The session was attended by 217 participants, 130 completed the survey and 153 opted into testing. Survey results indicated that participants were highly motivated to access general care as well as HCV testing and treatment. The most frequently reported barriers to testing and treatment were a previous negative test and being asymptomatic, respectively. Follow-up facilitators included a non-judgmental provider (88%), monetary incentives (67%), follow-up phone calls (77%), e-mails (66%) and text messages (58%). Of those who were RNA positive, 5 of 13 initiated treatment on-site. By using the results of the QIP in real-time, 6 of 13 were started after leaving the centre (one pending and one lost to follow-up). DISCUSSION AND CONCLUSIONS: The implementation of co-localised peer-led testing and treatment for HCV, along with persistent follow-up efforts, led to increases in linkage to care and treatment. Co-localisation of testing and care with substance-use services, especially if residential, is a viable, low-barrier strategy for increasing linkage to care among WWUD.

Evaluation of Hepatitis C Screening and Treatment Among Psychiatry Inpatients.

Objective: To evaluate uptake of hepatitis C virus (HCV) testing and treatment among psychiatry inpatients at Canada's largest mental health institution, the Centre for Addiction and Mental Health (CAMH).Methods: We reviewed medical records for all forensic and long-stay mental health patients from January 2017 to May 2021 to examine rates of HCV testing (antibody and RNA), treatment, and follow-up and completed a logistical regression to identify predictors associated with HCV antibody (Ab) screening among inpatients.Results: Of 1,031 patients, 73% (n = 753) were male, mean age was 44 years (range: 20-92), and mean length of stay was 7.1 months (range: 0 days-24 years). Most, 83% (n = 856), were diagnosed with schizophrenia spectrum disorders. In total, 652/1,031 (63%) of individuals in this cohort received HCV Ab screening. When broken down by admission rather than individual, 570/1,303 (44%) forensic admissions had an associated HCV Ab screening, and 318/1,450 (22%) non-forensic admissions had an associated HCV Ab screening. Individuals admitted to a forensic unit and those diagnosed with schizophrenia or substance use disorders were more likely to undergo HCV Ab screening, while individuals of Asian ethnicity were less likely (all P < .05). HCV Ab positivity was 4.9%, and most (84%, n = 27) HCV Ab-positive individuals had subsequent RNA testing, of whom 56% (n = 15) tested HCV RNA positive. Of 15 RNA-positive individuals, 10 initiated treatments, 7 on-site at CAMH and 3 at a local hepatology center. A total of 7 individuals (1 treated by specialists and 6 on-site) achieved sustained virological response or cure. The remaining 3 were lost to follow-up, 2 of whom were treated at the hepatology clinic.Conclusions: Based on the high prevalence of HCV, mental health inpatients should be included in groups for whom universal screening is recommended. Since on-site treatment was more successful than referral to external hepatology specialists, utilizing inpatient admission as an opportunity for HCV screening and treatment should receive more consideration.
