Attitudes and Practices of a Sample of Nova Scotian Physicians for the Implementation of HIV Pre-Exposure Prophylaxis

Exploring Food and Nutrition Programming for People Living With HIV/AIDS: Interviews With Service Providers in Nova Scotia, Canada

There is a lack of nutritional programming and resources available for people living with HIV/AIDS (PLWHA) in Nova Scotia, Canada. This is problematic for several reasons, including that adequate food and nutrition knowledge is integrated to effective medical therapy and wellness for PLWHA. The aim of this research was to explore and describe the beliefs, values, and experiences of HIV-service providers involved programming for PLWHA in Nova Scotia. Using a post-structuralist lens, semi-structured interviews were conducted with nine service providers. Thematic analysis of interview transcripts identified four main themes: (1) recognizing the social determinants of health, (2) acknowledging and disrupting layered stigma, (3) understanding the commensality, and (4) navigating and utilizing networks of care. These findings suggest that those developing, delivering, and evaluating food and nutrition-related programming must engage in community-inclusive approaches that recognize the varied social determinants of health that shape the lived of PLWHA, leverage existing networks and resources, and actively disrupt layered stigma. Also, in agreement with existing evidence, participants stressed the value of communicating and supporting the practice of eating together (commensality) and cultivating networks of care.

"To do so in a patient-centred way is not particularly lucrative": The effects of neoliberal health care on PrEP implementation and delivery

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) is a highly effective biomedical intervention used by HIV-negative people to prevent HIV acquisition. Despite increased use of PrEP worldwide, several barriers to PrEP implementation have resulted in insufficient uptake, inadequate adherence, and frequent discontinuation. Our objective was to interrogate the social, political, and economic conditions shaping PrEP implementation and delivery among gay, bisexual, queer and other men who have sex with men (GBQM) in Ontario, Canada.

METHODS

Six focus groups and three interviews with 20 stakeholders in Ontario (e.g., healthcare professionals, clinicians, community-based organization staff, and government staff) were conducted between July and October 2021. Participants were asked about the personal, workplace, and structural factors shaping PrEP delivery strategies for GBQM. Transcripts were analyzed using reflexive thematic analysis informed by the political economy of PrEP and employed a critique of neoliberalism.

RESULTS

Participants critiqued the problematic arrangements of the current healthcare system in Canada. Neoliberal governmentality and policies have resulted in inequitable PrEP care by establishing funding structures prioritizing profit and requiring patients and providers to function as individual entrepreneurs. Consequently, healthcare disparities are compounded for marginalized peoples who lack the resources and capacity to navigate existing healthcare systems. Participants identified several pathways to improve the implementation of PrEP, including greater institutional and governmental supports for PrEP and healthcare, leveraging communities and collaboration, and moving beyond risk-based health frameworks.

CONCLUSION

Socio-political-economic changes reflecting post-neoliberal principles are needed to overcome existing barriers to PrEP care, and sexual and reproductive healthcare more broadly.

Clinical Considerations in the Selection of Preexposure Prophylaxis for HIV Prevention in Canada

According to the Public Health Agency of Canada, approximately 62,050 people were living with HIV in Canada in 2018, and of those, 13% were undiagnosed. Currently, no single strategy provides complete protection or is universally effective across all demographic groups at risk for HIV. However, HIV preexposure prophylaxis (PrEP) is the newest HIV prevention strategy that shows promise. To date, two products have received an indication for PrEP by Health Canada: emtricitabine/tenofovir disoproxil fumarate (Truvada®; FTC/TDF) and emtricitabine/tenofovir alafenamide (Descovy®; FTC/TAF). Despite the high efficacy of these PrEP intervention methods, access to PrEP in Canada remains low. Identifying and addressing barriers to PrEP access, especially in high-risk groups, are necessary to reduce HIV transmission in Canada. While guidelines published by the Center for Disease Control and Prevention (CDC) include FTC/TAF information, the efficacy of FTC/TAF for PrEP has not yet been considered in Canada's clinical practice guidelines. Thus, the current paper reviews data regarding the use of FTC/TDF and FTC/TAF for PrEP, which may be useful for Canadian healthcare providers when counseling and implementing HIV prevention methods. The authors highlight these data in relation to various at-risk populations and review ongoing clinical trials investigating novel PrEP agents. Overall, FTC/TDF PrEP is effective for many populations, including men who have sex with men, transgender women, heterosexuals with partners living with HIV, and people who use drugs. While there is fewer data reported on the efficacy of FTC/TAF to date, recent clinical trials have demonstrated noninferiority of FTC/TAF in comparison to FTC/TDF. Notably, as studies have shown that FTC/TAF maintains renal function and bone mineral density to a greater extent than FTC/TDF, FTC/TAF may be a safer option for patients experiencing renal and/or bone dysfunction, for those at risk of renal and bone complications, and for those who develop FTC/TDF-related adverse events.
