Community perspectives on addressing and responding to HIV-testing, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) among African, Caribbean and Black (ACB) people in Ontario, Canada

BACKGROUND

The African, Caribbean, and Black (ACB) population of Ontario, Canada is comprised of individuals with diverse ethnic, cultural and linguistic backgrounds and experiences; some of whom have resided in Canada for many generations, and others who have migrated in recent decades. Even though the ACB population represents less than 3.5% of the Canadian population, this group accounts for 21.7% of all new HIV infections. It is well-documented that ACB populations, compared to the general population, experience multi-level barriers to accessing appropriate and responsive HIV services. In this paper, we present qualitative findings on the ACB population's experiences with HIV-testing, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) and obtain their perspectives on how to improve access.

METHODS

We conducted twelve Focus Group Discussions (FGDs), within a two-day World Café event and used socio-ecological framework and community-based participatory research (CBPR) approaches to guide this work. We meaningfully engaged ACB community members in discussions to identify barriers and facilitators to HIV testing, PEP and PrEP and how these may be addressed. The FGDs were transcribed verbatim and thematic analysis guided data interpretation. Credibility of data was established through data validation strategies such as external audit and peer-debriefing.

RESULTS

Our analyses revealed multi-level barriers that explain why ACB community members do not access HIV testing, PEP and PrEP. Fear, health beliefs, stigma and lack of information, were among the most frequently cited individual- and community-level barriers to care. Health system barriers included lack of provider awareness, issues related to cultural sensitivity and confidentiality, cost, and racism in the health care system. Participants identified multi-level strategies to address the HIV needs including community-based educational, health system and innovative inter-sectoral strategies.

CONCLUSION

CBPR, co-led by community members, is an important strategy for identifying the multi-level individual, interpersonal, community, institutional and structural factors that increase HIV vulnerability in ACB communities, notably anti-Black systemic racism. Study findings suggest the need for targeted community-based strategies and strategies aimed at reducing health system barriers to testing and care.

Nurse-led safer opioid supply and HIV pre-exposure prophylaxis: a novel pilot project

Introduction:

HIV pre-exposure prophylaxis (PrEP) is an effective intervention for preventing HIV infections yet is largely unknown to and underutilized among people who use drugs.

Methods:

To better provide services to this group, we present a prospective, single-group interventional study involving the creation of a partnership between a safer opioid supply program and an HIV PrEP program, both of which were nurse-led.

Results:

Overall, HIV PrEP was offered to 42 individuals within the safer opioid supply program, resulting in 55% (n = 23) acceptance. Almost half of the group that accepted PrEP identified as female, and nearly all participants were homeless and did not have a primary care provider. While it was challenging to obtain routine PrEP follow-up labs per guideline recommendations due to poor venous access, most participants were able to successfully stay on PrEP and maintained good medication adherence. There were no PrEP discontinuations due to renal impairment and no participants tested positive for HIV.

Conclusion:

This novel integration of programs appeared to be a highly effective way to expand access to HIV prevention among people who use drugs. Given the historical and current mistreatment of people who use drugs within the healthcare system, rapport and trust were essential to the uptake of HIV PrEP services. Further, the importance of infectious disease screening among people who use drugs is underscored, and built-in program flexibility and low barrier access is essential.

HIV Vulnerability Among Survival Sex Workers Through Sexual Violence and Drug Taking in a Qualitative Study From Victoria, Canada, With Additional Implications for Pre-exposure Prophylaxis for Sex Workers

Objective: This qualitative study investigates how social and structural forces mediate vulnerability to HIV infection and transmission among survival sex workers, their clients, and their non-commercial, intimate partners-with especial focus on sexual violence and drug taking. Method: I employed an adapted grounded theory approach to conducting and analyzing (n = 9) open-ended, in-depth interviews with a convenience sample of currently working (and recently exited) survival sex workers from a community setting in Victoria, Canada. Findings: Participants revealed important contexts and conditions under which they were vulnerable to HIV infection. At the behavioural level, participants were aware of how HIV could be transmitted (condomless sex and sharing drug equipment), yet participants voiced strongly how structural and systemic features (for instance, client violence, the need for drugs, and "bad date" referrals) could squeeze and constrain their agency to take up safer practices, mediating their optimal HIV health and safety. Some participants reported strained relationships with police because of previous drug involvement. Conclusion: Survival sex workers constitute a health population vulnerable to HIV infection, and ensuring there could be a supportive (outreach) community replete with HIV resources is paramount. The availability of safer sex and drug equipment play important roles in HIV behavioural prevention efforts. However, uptake of pre-exposure prophylaxis (PrEP) at no cost in the Canadian province of British Columbia could be an important and beneficial structural intervention for non-injection drug taking cis-female sex workers in this study who are presently ineligible for no cost PrEP.

Automated STI/HIV risk assessments: Testing an online clinical algorithm in Ottawa, Canada

Despite the ongoing transmission of sexually transmitted infections (STIs) and HIV, many people became unable to access testing due to COVID-19. To address this, we created a mail-out HIV self-test kit, which could be delivered without restrictions in our region. The uptake and feedback from this project made us realize that comprehensive STI testing was being sought. To ensure testing occurred correctly-that is, it would be targeted at the persons most affected by STIs/HIV-we automated clinical decision-making. We built this model based on a 2-by-2 matrix that plots the risk of STI/HIV transmission and risk of STI/HIV exposure. The intercept of these two measures classifies a person as low, medium, or high risk. After automating this logic, 16 expert clinicians in STI/HIV care tested this system with over 400 test patient cases and refined the algorithm until it yielded the exact outcomes that these clinicians would offer patients based on guidelines. Findings of interest are that the scale of the y-axis is exponential, in that risk factors for exposure do not climb cumulatively but do so according to a quadratic equation. This helps ensure that testing services are targeted at those who are most inequitably burdened by these infections.

Immediate PrEP after PEP: Results from an Observational Nurse-Led PEP2PrEP Study

Patients who use post-exposure prophylaxis (PEP) are at ongoing risk for HIV acquisition after completing PEP. While the Centers for Disease Control and Prevention recommends pre-exposure prophylaxis (PrEP) use immediately after PEP, some practitioners are hesitant to offer PEP-to-PrEP (PEP2PrEP). We began offering PEP2PrEP in the sexually transmitted infection clinic in Ottawa, Canada on August 5, 2018. During the first 16 months of PEP2PrEP, 61 patients requested PEP and 46 were initiated; 30 of these patients agreed to PEP2PrEP and 26 followed through. None of our PEP patients had confirmed HIV exposures; all fulfilled the initiation criterion of condomless anal sex with a male partner of unknown HIV-status. During the study, the number of PEP requests and initiations was statistical unchanged, yet the seroconversion rate among patients who used PEP decreased from 1.7% pre-PEP2PrEP to 0% post-PEP2PrEP. Regarding follow-up, most discontinuations occurred between the PrEP intake and 1-month follow-up visit.

A Review of the State of HIV Nursing Science With Sexual Orientation, Gender Identity/Expression Peoples

ABSTRACT

Throughout the HIV pandemic, nurses have contributed to or led approaches to understanding the effects of HIV disease at individual and societal levels. Nurses have advocated for socially just care for more than a century, and our efforts have created a foundation on which to further build the state of HIV nursing science with sexual orientation and gender identity/expression (SOGI) Peoples. Nurses have also participated in the development of approaches to manage HIV disease for and in collaboration with populations directly affected by the disease. Our inclusive approach was guided by an international human rights legal framework to review the state of nursing science in HIV with SOGI Peoples. We identified articles that provide practice guidance (n = 44) and interventions (n = 26) to address the health concerns of SOGI Peoples and our communities. Practice guidance articles were categorized by SOGI group: SOGI People collectively, bisexual, transgender, cisgender lesbian, women who have sex with women, cisgender gay men, and men who have sex with men. Interventions were categorized by societal level (i.e., individual, family, and structural). Our review revealed opportunities for future HIV nursing science and practices that are inclusive of SOGI Peoples. Through integrated collaborative efforts, nurses can help SOGI communities achieve optimal health outcomes that are based on dignity and respect for human rights.

Nurse-led PrEP-RN clinic: a prospective cohort study exploring task-Shifting HIV prevention to public health nurses

OBJECTIVE

To report the results of a nurse-led pre-exposure prophylaxis (PrEP) delivery service.

DESIGN

This was a prospective cohort study conducted from 5 August 2018 to 4 March 2020. It involved manual chart review to collect data. Variables were described using frequencies and percentages and analysed using χ2 testing. Those significant in bivariate analysis were retained and entered into a binary multiple logistic regression. Hierarchical modelling was used, and only significant factors were retained.

SETTING

This study occurred in an urban public health unit and community-based sexually transmitted infection (STI) clinic in Ottawa, Canada.

PARTICIPANTS

Of all persons who were diagnosed with a bacterial STI in Ottawa and everyone who presented to our STI clinic during the study period, there were 347 patients who met our high-risk criteria for PrEP; these criteria included patients who newly presented with any of the following: HIV contacts, diagnosed with a bacterial STI or single use of HIV PEP. Further, eligibility could be determined based on clinical judgement. Patients who met the foregoing criteria were appropriate for PrEP-RN, while lower-risk patients were referred to elsewhere. Of the 347 patients who met our high-risk criteria, 47% accepted and 53% declined. Of those who accepted, 80% selected PrEP-registered nurse (RN).

PRIMARY AND SECONDARY OUTCOME MEASURES

Uptake, acceptance, engagement and attrition factors of participants who obtained PrEP through PrEP-RN.

FINDINGS

69% of participants who were eligible attended their intake PrEP-RN visit. 66% were retained in care. Half of participants continued PrEP and half were lost to follow-up. We found no significant differences in the uptake, acceptance, engagement and attrition factors of participants who accessed PrEP-RN regarding reason for referral, age, ethnicity, sexual orientation, annual income, education attainted, insurance status, if they have a primary care provider, presence or absence of depression or anxiety and evidence of newly acquired STI during the study period.

CONCLUSIONS

Nurse-led PrEP is an appropriate strategy for PrEP delivery.

Examining patient characteristics and HIV-related risks among women with syphilis as indicators for pre-exposure prophylaxis in a nurse-led program (PrEP-RN)

Current HIV pre-exposure prophylaxis (PrEP) guidelines primarily target men who have sex with men (MSM) as candidates for HIV prevention; however, such recommendations often come at the expense of other ethnic and gender minorities, including women. To address barriers to PrEP care among non-MSM, we developed and implemented the first nurse-led PrEP program in Canada, known as PrEP-RN. As part of PrEP-RN, patients who meet objective indicators of HIV risk are offered a referral for PrEP, regardless of sexual orientation. One such measure is syphilis, which has increased in incidence among various population groups and is known to cause biological vulnerabilities to HIV. To better understand HIV-related risks and assess intentions for PrEP use among women, we undertook an 18-month retrospective review of syphilis diagnoses within this group in Ottawa, Canada. As part of this review, we examined 23 patient files, noting their unique characteristics, socio-behavioural risk factors, and noted barriers to PrEP uptake. While none of the women diagnosed with syphilis were diagnosed with HIV, the findings raise some important considerations to facilitate opportunities for HIV prevention among non-MSM, which must take into consideration individual risk practices, sexual health histories, and population groups.

A review of HIV pre-exposure prophylaxis (PrEP) programmes by delivery models in the Asia-Pacific through the healthcare accessibility framework

INTRODUCTION

In the Asia-Pacific, pre-exposure prophylaxis (PrEP) is a newly introduced public health intervention for minimizing HIV transmission, the coverage of which has remained limited. The best delivery models and strategies for broadening access of the vulnerable communities are not fully known. This review identified PrEP programmes reported in the Asia-Pacific, which were classified by delivery models and assessed with a healthcare accessibility framework.

METHODS

We performed a literature search on PubMed and Ovid MEDLINE using relevant search terms, manual searched grey literature by visiting relevant websites, examined reference lists and contacted authors for clarification of included PrEP programmes reported through July 2019. A structured table was used for data extraction and summarizing findings in accordance with the five constructs of approachability, acceptability, availability, affordability and appropriateness grounded in the conceptual framework of Healthcare Accessibility.

RESULTS AND DISCUSSION

This literature search yielded a total of 1308 publications; 119 full texts and abstracts were screened, and 24 publications were included in the review. We identified 11 programmes implemented in seven cities/countries in the Asia-Pacific. A typology of four PrEP delivery models was delineated: (a) fee-based public service model; (b) fee-based community setting model; (c) free public service model; and (d) free community setting model. Overall, the free community setting model was most commonly adopted in the Asia-Pacific, with the strength to boost the capacity of facility and human resources, which enhanced "approachability", "availability" and "acceptability." The free public service model was characterized by components designed in improving "approachability," "availability" and "appropriateness," with attention on equity in accessing PrEP. Among free-based models, long-term affordability both to the government and PrEP users would need to be maximized to increase accessibility. Alongside the need for raising awareness, supportive environments and ensuring timely access were means for enabling the development of a sustainable PrEP service.

CONCLUSION

PrEP programmes could be classified by delivery models through the five constructs of healthcare accessibility. While the coverage of PrEP remains limited in the Asia-Pacific, an evaluation of these models could benchmark best practices, which would in turn allow effective models to be designed.
