Leaving no one behind? An equity analysis of the HIV care cascade among a cohort of people living with HIV in Manitoba, Canada

Explaining inequity in knowledge, attitude, and services related to HIV/AIDS: a systematic review

BACKGROUND

Equitable service provision and coverage are important responses to end the threat of the HIV/AIDS pandemic. Understanding inequity supports policies and programmes to deliver tailored interventions. There is continuous evidence generation on inequity in HIV/AIDS services. However, there was a lack of evidence on the global picture of inequity in behavioural and biomedical services related to HIV/AIDS. This systematic review assessed inequities in knowledge, attitude, HIV testing, and ART coverage across individual-level social groups and multiple (dis)advantage categories.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, with a PROSPERO registration number CRD42024521247. The risk of bias was assessed by using Hoy et al's and Joanna Brigg's quality appraisal checklists for cross-sectional quantitative and qualitative studies, respectively. The search date was from inception to the final database search date (May 29, 2023). The included articles were either quantitative or qualitative studies. We used mixed-methods approach to analyse the data from the review articles. Quantitative descriptive analysis was conducted to estimate frequency of articles published from different countries around the world. Qualitative content analysis of the findings from the original studies was conducted using the PROGRESS plus framework which stands for: place of residence, occupation or employment status, gender, religion, education status, socioeconomic status, and social capital.

RESULTS

Out of 6,029 articles that were accessed and screened, only 72 articles met the inclusion criteria. More articles on HIV-related equity in knowledge, attitude, testing, and ART were published in developed countries than in developing countries. Individuals from higher-income households had better knowledge about HIV/AIDS. Unfavourable attitudes towards people living with HIV and HIV/AIDS-associated stigma were common among women. HIV/AIDS service coverage (HIV testing or ART coverage) was higher among richer and urban residents. HIV/AIDS-associated stigma and lower levels of knowledge about HIV/AIDS were observed among multiple disadvantageous groups due to the intersection of two or more identities.

CONCLUSIONS

The current review revealed that there have been disparities in HIV/AIDS services between social classes. Ending service disparity towards the global threat of HIV/AIDS demands tailored interventions based on socially disadvantaged groups (e.g., poor, rural dwellers, and women) and intersectional determinants. There is a need to understand the deep-rooted causes of inequity and the challenges that an equity-oriented system faces over time. More studies on inequity are needed, including intersectional inequity, which has been rarely studied in developing countries.

Programme science: a route to effective coverage and population-level impact for HIV and sexually transmitted infection prevention

Improvements in context-specific programming are essential to address HIV and other sexually transmitted and blood-borne infection epidemics globally. A programme science approach emphasises the need for context-specific evidence and knowledge, generated on an ongoing basis, to inform timely and appropriate programmatic decisions. We aim to accelerate and improve the use of embedded research, inquiry, and learning to optimise population-level impact of public health programmes and to introduce an effective programme coverage framework as one tool to facilitate this goal. The framework was developed in partnership with public health experts in HIV and sexually transmitted and blood-borne infections through several workshops and meetings. The framework is a practice-based tool that centres on the use of data from iterative cycles of programme-embedded research and learning, as well as routine programme monitoring, to refine the strategy and implementation of a programme. This programme science approach aims to reduce programme coverage gaps, to optimise impact at the population level, and to achieve effective coverage. This framework should facilitate the generation of programme-embedded research and learning agendas to inform resource allocation, optimise population-level impact, and achieve equitable and effective programme coverage.

Structural violence and the uncertainty of viral undetectability for African, Caribbean and Black people living with HIV in Canada: an institutional ethnography

Biomedical advances in healthcare and antiretroviral treatment or therapy (ART) have transformed HIV/AIDS from a death sentence to a manageable chronic disease. Studies demonstrate that people living with HIV who adhere to antiretroviral therapy can achieve viral suppression or undetectability, which is fundamental for optimizing health outcomes, decreasing HIV-related mortality and morbidity, and preventing HIV transmission. African, Caribbean, and Black (ACB) communities in Canada remain structurally disadvantaged and bear a disproportionate burden of HIV despite biomedical advancements in HIV treatment and prevention. This institutional ethnography orients to the concept of 'structural violence' to illuminate how inequities shape the daily experiences of ACB people living with HIV across the HIV care cascade. We conducted textual analysis and in-depth interviews with ACB people living with HIV (n = 20) and health professionals including healthcare providers, social workers, frontline workers, and health policy actors (n = 15). Study findings produce a cumulative understanding that biomedical HIV discourses and practices ignore structural violence embedded in Canada's social fabric, including legislation, policies and institutional practices that produce inequities and shape the social world of Black communities. Findings show that inequities in structural and social determinants of health such as food insecurity, financial and housing instability, homelessness, precarious immigration status, stigma, racial discrimination, anti-Black racism, criminalization of HIV non-disclosure, health systems barriers and privacy concerns intersect to constrain engagement and retention in HIV healthcare and ART adherence, contributing to the uncertainty of achieving and maintaining undetectability and violating their right to health. Biomedical discourses and practices, and inequities reduce Black people to a stigmatized, pathologized, and impoverished detectable viral underclass. Black people perceived as nonadherent to ART and maintain detectable viral loads are considered "bad" patients while privileged individuals who achieve undetectability are considered "good" patients. An effective response to ending HIV/AIDS requires implementing policies and institutional practices that address inequities in structural and social determinants of health among ACB people.

Universal Health Coverage for Antiretroviral Treatment: A Review

Universal health coverage is essential for the progress to end threats of the acquired immunodeficiency syndrome epidemic. The current review assesses the publication rate, strategies and barriers for antiretroviral therapy (ART) coverage, equity, quality of care, and financial protection. We searched Web of Science, PubMed, and Google Scholar. Of the available articles, 43.13% were on ART coverage, 40.28% were on financial protection, 10.43% were on quality of care, and 6.16% were on equity. A lack of ART, fear of unwanted disclosure, lack of transportation, unaffordable health care costs, long waiting time to receive care, and poverty were barriers to ART coverage. Catastrophic health care costs were higher among individuals who were living in rural settings, walked greater distances to reach health care institutions, had a lower socioeconomic status, and were immunocompromised. There were challenges to the provision of quality of care, including health care providers' inadequate salary, high workload and inadequate health workforce, inappropriate infrastructure, lack of training opportunities, unclear division of responsibility, and the presence of strict auditing. In conclusion, ART coverage was below the global average, and key populations were disproportionally less covered with ART in most countries. Huge catastrophic health expenditures were observed. UHC contexts of ART will be improved by reaching people with poor socioeconomic status, delivering appropriate services, establishing a proper health workforce and service stewardship.

A two-day workshop reviewing Canadian provincial and national HIV care cascade indicators, reporting, challenges, and recommendations

BACKGROUND

The HIV care cascade is an indicators-framework used to assess achievement of HIV clinical targets including HIV diagnosis, HIV care initiation and retention, initiation of antiretroviral therapy, and attainment of viral suppression for people living with HIV.

METHODS

The HIV Care Cascade Research Development Team at the CIHR Canadian HIV Trials Network Clinical Care and Management Core hosted a two-day virtual workshop to present HIV care cascade data collected nationally from local and provincial clinical settings and national cohort studies. The article summarizes the workshop presentations including the indicators used and available findings and presents the discussed challenges and recommendations.

RESULTS

Identified challenges included (1) inconsistent HIV care cascade indicator definitions, (2) variability between the use of nested UNAIDS's targets and HIV care cascade indicators, (3) variable analytic approaches based on differing data sources, (4) reporting difficulties in some regions due to a lack of integration across data platforms, (5) lack of robust data on the first stage of the care cascade at the sub-national level, and (6) inability to integrate key socio-demographic data to estimate population-specific care cascade shortfalls.

CONCLUSION

There were four recommendations: standardization of HIV care cascade indicators and analyses, additional funding for HIV care cascade data collection, database maintenance and analyses at all levels, qualitative interviews and case studies characterizing the stories behind the care cascade findings, and employing targeted positive-action programs to increase engagement of key populations in each HIV care cascade stage.

Perceptions of hepatitis C treatment and reinfection risk among HIV-positive men who have sex with men and engage in high risk behaviours for hepatitis C transmission: The CEASE qualitative study

BACKGROUND

Globally, treatment uptake for hepatitis C virus (HCV) infection among HIV-HCV coinfected men who have sex with men (MSM) has substantially increased since the advent of interferon-free direct-acting antivirals (DAA). However, HIV-positive MSM who engage in high risk behaviours are at an increased risk of HCV reinfection post-treatment. The aim of this study was to investigate perceptions of HCV diagnosis, treatment and reinfection risk among HCV-HIV coinfected MSM who engage in drug use and/or high risk sexual behavior in Sydney, Australia.

METHODS

Participants were recruited from the Control and Elimination within AuStralia of HEpatitis C from people living with HIV (CEASE) cohort (n=402) who reported engaging in drug use and/or high risk sexual behavior for transmission of HCV infection. Participants were interviewed about their perceptions of HCV diagnosis, treatment, and reinfection risk. Interview data were transcribed, coded, and analyzed thematically.

RESULTS

Of 33 participants interviewed (mean age 49 years), many participants were 'shocked' by their HCV diagnosis. Participants who believed they acquired HCV infection through sexual exposure felt it was important that their healthcare practitioner agreed with their perspective to mitigate stigmatizing experiences. Overall, participants expressed high satisfaction with their treatment experience due to long-standing therapeutic relationships with their HIV physician. Many participants expressed knowledge of how to prevent HCV reinfection from injection drug use, yet other than condom usage, most were unsure how to reduce high risk sexual activity with such discussions occurring less frequently with healthcare practitioners.

CONCLUSION

Findings indicate that MSM who engage in drug use and high risk sexual activity would benefit from additional education on reducing reinfection risk through sexual activity and services to reduce substance use, if requested.

Legislatively Excluded, Medically Uninsured and Structurally Violated: The Social Organization of HIV Healthcare for African, Caribbean and Black Immigrants with Precarious Immigration Status in Toronto, Canada

African, Caribbean and Black immigrants face persistent legislative barriers to accessing healthcare services in Canada. This Institutional Ethnography examines how structural violence and exclusionary legislative frameworks restrict the right to HIV healthcare access for many Black immigrants. We conducted semi-structured interviews with Black immigrants living with HIV (n = 20) and healthcare workers in Toronto, Canada (n = 15), and analyzed relevant policy texts. Findings revealed that exclusionary immigration and healthcare legislation shaping and regulating immigrants' right to health restricted access to public resources, including health insurance and HIV healthcare and related services, subjecting Black immigrants with precarious status to structural violence. Healthcare providers and administrative staff worked as healthcare gatekeepers. These barriers undermine public health efforts of advancing health equity and ending HIV "while leaving no one behind." We urge continued policy reforms in Canada's immigration and healthcare systems regarding HIV care access for Canada's precarious status immigrants.

Longitudinal analysis of HIV outcomes for persons living with HIV in non-urban areas in southern Alberta, Canada

BACKGROUND

Many challenges remain in successfully engaging people with HIV (PWH) into lifelong HIV care. Living in non-urban or rural areas has been associated with worse outcomes. Uncertainties remain regarding how to provide optimal HIV care in non-urban areas.

METHODS

Using a retrospective descriptive analysis framework, we compared multiple measurable HIV care metrics over time on the basis of urban versus non-urban residency, under a centralized HIV care model. We examined rates of HIV diagnosis, access to and retention in HIV care, and longitudinal outcomes for all newly diagnosed PWH between January 1, 2008, and January 1, 2020, categorized by their home location at the time of HIV diagnosis in southern Alberta.

RESULTS

Of 719 newly diagnosed PWH, 619 (86%) lived in urban areas and 100 (14%) lived in non-urban areas. At HIV diagnosis, the groups had no significant differences in initial CD4 count or clinical characteristics (p = 0.73). Non-urban PWH, however, had slightly longer times to accessing HIV care and initiating antiretroviral therapy (ART) (p < 0.01). Non-urban PWH showed trends toward slightly lower retention in care and lower sustained ART use, with higher rates of unsuppressed viral loads at 12, 24, and 36 months after diagnosis (p < 0.01). However, by 2020 both cohorts had suppression rates above 90%.

CONCLUSIONS

Sustained retention in care was more challenging for non-urban PWH; however, adherence to ART and viral suppression rates were more than 90%. Although encouraging, challenges remain in identifying and reducing unique barriers for optimal care of PWH living in non-urban areas.

'Not just one box that you tick off' - Deconstructing the hepatitis C care cascade in the interferon-free direct acting antiviral era from the client perspective

BACKGROUND

To achieve hepatitis C viral (HCV) elimination targets set by the World Health Organisation, pillars of the HCV care cascade are often referenced to track progress. The aim of this qualitative study was to explore the limitations of the care cascade framework through the real-world accounts of 'HCV journeys' among people who inject drugs (PWID), with particular attention to the intersection of PWID agency and structural determinants in the healthcare system.

METHODS

An in-depth analysis was conducted on five case studies to better understand participant experiences 'behind the cascade pillars'. The five case studies were drawn from the ETHOS Engage cohort as exemplars of the real-world complexities of people's HCV cascade journeys. Inclusion criteria for the qualitative study were participant has voluntarily signed the informed consent form, aged ≥18 years, HCV antibody positive by self-report, clients of selected sites participating in the ETHOS Engage cohort, and sufficiently proficient in English to participate in an interview. Thirty-four semi-structured interviews were conducted with participants who had received or had not received HCV treatment to identify barriers and facilitators to HCV care.

RESULTS

Participants 'housed' at the 'HCV RNA diagnosed pillar' (n = 2; Will; Julie) reported withholding their HCV serostatus in certain healthcare settings for fear that disclosure would lead to discriminatory decision-making from their treating physician. among participants who had completed treatment (n = 3; Corey; John; Nora) two reported still being unsure of their HCV status >6 months post-treatment. Ongoing feelings of frustration and shame were expressed in this 'post-cure care pillar' due to a perceived lack of quality care from clinic services and continued uneasiness when discussing drug use and reinfection while receiving opioid agonist treatment (OAT). Both case 'categories' described often tenuous therapeutic relationships with their physicians and recommended task-shifting to nurses and trusted case workers for ongoing care.

CONCLUSION

The care cascade provides a linear, two dimensional snapshot of clinical targets. Our findings illuminate structural barriers not visible behind its 'static' pillars, presenting insights into experiences among PWID otherwise dismissed as 'disengaged' or 'lost to follow-up'.

Unmasking legislative constraints: An institutional ethnography of linkage and engagement in HIV healthcare for African, Caribbean, and Black people in Ontario, Canada

The Human Immunodeficiency Virus (HIV) epidemic significantly impacts African, Caribbean, and Black (ACB) immigrants in Canada. Health scholarship has revealed striking injustices within Canada's public healthcare system that restrict access to healthcare and violate the human rights of ACB immigrants living with HIV who are marginalized. We conducted an institutional ethnography to comprehensively understand how HIV healthcare in Ontario is organized and experienced by ACB immigrants, focusing on unjust and discriminatory legislative frameworks and institutional practices regulating access to publicly funded healthcare resources and services. We interviewed 20 ACB immigrants and 15 healthcare workers, including specialists, primary care providers, immigration physicians, and social workers. We found a disjuncture between the organization of HIV healthcare in Ontario and how ACB immigrants experienced access to care. We uncovered how immigration, public health and healthcare laws and related institutional practices intersect to produce structural violence which create barriers and missed opportunities to timely linkage and engagement in HIV healthcare. Black immigrants' accounts revealed that they underwent mandatory HIV under the Immigration Medical Examination policy (IME) without providing informed consent and receiving pre and post-test counselling. Furthermore, Black immigrants did not receive referrals and were not adequately linked to care following HIV diagnosis. Troubling encounters with immigration and public health state agents and healthcare legislative barriers including difficulty finding a physician, the 3-month waiting period under the Ontario Health Insurance Plan (OHIP), long wait times, lack of drug coverage, and stigma, discrimination, and anti-Black racism shaped and affected Black people's linkage and engagement in HIV care. We elucidate how the legislative and structural organization of healthcare regulated and constrained health service access for ACB immigrants living with HIV, including their ability to "achieve" HIV undetectability.
