Abstract
Introduction
Women, both cisgender and transgender, experience persistent inequities in sexual and reproductive health (SRH) due to sexism, transphobia, racism, and systemic discrimination. In Canada and globally, these intersecting inequities are exacerbated by limited, biomedical, and colonial models of care that overlook women's needs, leaving them underserved in HIV and sexually transmitted and blood-borne infection (STBBI) prevention. Our study describes the development of the Women-Centred Prevention (W-PREV) Model, designed to integrate HIV/STBBI prevention and SRH through an intersectional, women-led approach.
Methods
Guided by the implementation science Knowledge-to-Action Framework, we adapted the existing Women-Centred HIV Care (WCHC) Model to address HIV/STBBI prevention and SRH needs for women. The development process included a rapid scoping review, environmental scan, and stakeholder interviews with women, clinicians, and service providers in two Canadian provinces, Ontario and Saskatchewan.
Results
Findings highlighted that structural barriers such as housing insecurity, stigma, and systemic racism often overshadow women's ability to prioritize HIV/STBBI prevention and SRH. The resulting W-PREV Model addresses these realities by integrating HIV/STBBI prevention within six interrelated domains: SRH care, gender-specific care, mental health care, substance use and harm reduction, social connection and peer support, and individual capacity building. The model's trauma- and violence-aware, person-centred, and culturally responsive foundation ensures prevention is accessible, relevant, and empowering across the life course. W-PREV is distinct in its focus on HIV/STBBI prevention and early intervention, integrating SRH, peer support, and outreach within community and clinical settings.
Conclusions
The W-PREV Model provides a comprehensive, women-centred framework that bridges clinical and community settings to support personalized HIV/STBBI prevention and SRH self-care. By grounding prevention in women's lived experiences and peer support, W-PREV promotes equitable, holistic, and sustainable care for women and gender diverse people in Canada.

Plain Language Summary
Why was this research done?
HIV and sexually transmitted and blood-borne infections (STBBI) rates are rising in women in Ontario and Saskatchewan. Women persistently face gaps in sexual and reproductive health care and HIV/STBBI prevention due to intersecting social and structural inequities. The Women-Centred Prevention (W-PREV) Model of Care was created to better support women who are often overlooked in traditional health systems. It uses a women-centred, trauma-informed approach that integrates clinical and community services to empower women, increase HIV/STBBI prevention access, and improve health outcomes.
How does this research contribute to the field?
This research describes the methods used to develop an intersectional, women-centred approach to HIV and STBBI prevention. It offers a practical, evidence-based model of care that can be used in different settings to improve health equity for women. It also shows that clinical and community services need to work together to better support women who face barriers to HIV/STBBI prevention and sexual and reproductive health care.
What are your research's implications for theory, practice, or policy?
This work represents a step towards responding to the unmet sexual and reproductive health needs of women in Canada. The W-PREV Model is constructed so it may be tailored to diverse care contexts. It provides a practical framework that can be used by healthcare providers, outreach workers, and community organizations to improve care for women and gender diverse people. Our team is continuing this work by testing and implementing the W-PREV Model through a clinical and community-based program in Ontario and Saskatchewan.

Introduction
Globally, women experience systemic and gender-based inequities that contribute to problematic patterns of violence and poor sexual and reproductive health (SRH).1–3 While Canada is committed to ending the HIV epidemic, HIV diagnoses increased nearly a quarter (24.9%) between 2021 and 2022, with the national rate jumping from 3.8 to 4.7 per 100,000 population. 4 Cisgender (cis) women represent 25.3% of all people living with HIV in Canada, but accounted for 35.5% of all new infections in 2022. 5 Also, for the first time, heterosexual sex became the leading route of HIV transmission in 2022. 4
Provincially, both Ontario and Saskatchewan face distinct but pressing challenges. Women in Saskatchewan bear the brunt of new HIV infections in Canada.4,6 In 2019, cis women represented about half of new HIV diagnoses in Saskatchewan.4,6 In 2018, among reproductive-age cis women in Saskatchewan, the HIV incidence was nearly four times the overall Canadian rate, highlighting a striking difference in HIV prevention needs. 7 Since 2020 in Ontario, cis women have also comprised a growing proportion of new HIV infections. 4 In 2021, young cis women (age 15-19) were at higher risk of HIV acquisition than their male counterparts.4,8 Globally, transgender (trans) women have a significantly higher HIV prevalence than trans men (19.9% vs 2.6%), with both groups disproportionately affected compared to the general population. 9
Moreover, rates of sexually transmitted infections (STIs) are also rising in Canada. Between 2012 and 2019, rates in Canada for chlamydia and gonorrhea increased by 22.0% and 151.0%, respectively. 10 In 2021, cis women represented 59.0% of reported chlamydia cases and 37.0% of reported gonorrhea cases. 10 Ontario and Saskatchewan account for a significant portion of new chlamydia and gonorrhea cases. In Ontario, from 2015 to 2022, young cis women (age 13-19) represented the majority of new chlamydia and gonorrhea cases in comparison to young cis men (74.6% vs 25.4% and 61.2% vs 38.8%, respectively). 11 The resurgence of infectious syphilis is particularly alarming. Between 2017 and 2021, the rate of infectious syphilis increased by 729.0% in cis women and only 96% in cis men. 12 Rising infections among reproductive-age people have also driven a 1271.0% increase in congenital syphilis cases during the same period. 12 Saskatchewan continues to experience some of the highest rates of early congenital syphilis in the country, with 189.7 cases per 100,000 live births in 2022, compared to 32.7 cases nationally and 20.0 cases per 100,000 in Ontario. 13
Women face heightened vulnerability to HIV and other sexually transmitted and blood-borne infections (STBBIs) due to intersecting social, structural, and biological factors. 14 Intersectionality Theory is a framework used to understand how systems of oppression compound and interlock to perpetuate inequality, including racism, sexism, ableism, and classism.15–17 It further suggests that not all forms of inequality are experienced in the same way.15,16 The theory compels us to build holistic solutions that acknowledge how various forms of inequality exacerbate each other and are shaped by all parts of one's identity, rather than a sum of separate parts. 15 In HIV prevention, the Intersectionality Theory examines how the intersection of (1) health conditions (eg, HIV, mental illness, substance use disorder); (2) positions and identities (eg, race, gender, sexual orientation, immigration status); and (3) behaviors (eg, substance use, sex work) shape experiences of stigma and influence HIV risk. 18 Systemic racism, settler colonialism, and social marginalization are well-documented drivers of HIV and STBBI acquisition, contributing to disproportionate rates among racialized, Indigenous, and newcomer women in Canada.19,20 These inequities are even more pronounced for trans and gender diverse women. 21 Many women navigate complex power dynamics, such as transactional or survival sex, that may limit their ability to negotiate safer sexual practices, thereby increasing their HIV/STBBI exposure risk. 14 Lacombe-Duncan and Olawale found that high rates of violence (eg, bullying, familial rejection) in childhood and early adulthood experienced by trans women increased HIV vulnerability. 22 Women who use drugs are at further risk of acquiring HIV and blood-borne infections through intravenous drug use. 23 Biological factors also contribute to an increased risk for HIV/STBBI acquisition for women in comparison to men when engaging in penetrative vaginal intercourse.24–26 The risk of gonorrhea and HIV transmission from males to females during vaginal intercourse is nearly 3-fold and 2-fold greater than females to males, respectively.24–26
Despite the availability of effective HIV prevention tools, uptake remains disproportionately higher among gay, bisexual, and other men who have sex with men (gbMSM) compared to women in Canada. 27 This imbalance has contributed to declining HIV incidence among men, while rates among women have remained stagnant or increased.20,28 Current prevention strategies continue to fall short for women because they inadequately address the root causes of HIV and STBBI acquisition. For instance, testing can only interrupt transmission if treatment is accessed and adhered to – both of which depend on factors such as drug coverage, socioeconomic stability, and continuity of care.29,30 Similarly, condom use, often framed as a gender-neutral prevention method, is constrained by social and gendered power imbalances. Condoms remain largely male-controlled, and expectations that women should purchase, carry, and insist on their use conflict with societal norms that construct women as passive participants in sexual relationships.31,32
Pre-exposure prophylaxis (PrEP), one of the few self-controlled prevention tools, has not been widely promoted or researched for women in Canada.33–36 Popovic et al reported that almost all (98.0%) of PrEP users in nine Canadian provinces between 2018 and 2021 were male.
27
Additionally, PrEP requires a woman and/or her care provider to be aware of PrEP, have access to privacy for acquiring a prescription, storing and taking medication, and believe she is at risk of HIV.
37
These barriers are all amplified by HIV-related stigma.
37
Gaps in knowledge dissemination also cause many women to be unaware of alternatives to PrEP, like HIV post-exposure prophylaxis (PEP) and PEP-in-pocket (PIP).38,39 Similarly, options like DoxyPEP for bacterial STI prevention are overlooked for women, as these medications also predominantly focus on gbMSM.
40
These tools represent a universal approach to HIV/STBBI prevention
This lack of progress is further exacerbated by the minimal integration of care addressing the root causes of HIV/STBBI acquisition into HIV/STBBI prevention. For example, Salway et al found that 39% of clients at a sexual health clinic in a large Canadian urban center reported a need for mental health or substance-related care, but siloed services created gaps in accessing this care along with HIV/STBBI services. 41 Further, a study in a major Canadian city highlighted that young female sex workers felt that sexual healthcare providers would be uninformed about their social experiences and had concerns about confidentiality and being judged. 42 Other gaps include a lack of comprehensive care for conception and contraception needs.42,43 Studies suggest that women living with HIV are less likely to receive pre-conception counseling and associated costs, clinic and procedure disintegration, and intersecting forms of stigma create barriers to accessing desired contraception methods.42,43
Therefore, integrated, women-centred prevention approaches are urgently needed. Building on findings from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) and a women-centred care model used in Vancouver, the Women-Centred HIV Care (WCHC) Model was developed as an evidence-based, holistic framework addressing the needs of women living with HIV.36,44–46 The WCHC Model was found to be acceptable among cis and trans women and individuals with transfeminine experience.45,47 Depicted as a house, the model places trauma- and violence-aware care as its foundation, person-centred and social determinant–focused care on the first floor, and integrated HIV, women's and mental health on the second, and finally peer support and leadership as the roof. 44
In this article, we describe the adaptation of the WCHC Model into a prevention-focused framework using an implementation science approach guided by the Knowledge-to-Action Framework. 48 Through a rapid scoping review, environmental scan, and qualitative stakeholder interviews, we developed the Women-Centred Prevention (W-PREV) Model—a holistic, intersectional model of HIV/STBBI prevention and SRH care. The W-PREV Model delivers trauma- and violence-aware, person-centred, and culturally sensitive care that integrates SRH care and services, mental health and substance use care, and peer and individual support to address women's unique needs. Grounded in empirical evidence and lived experience, the W-PREV Model aims to enhance HIV/STBBI prevention and promote SRH and mental well-being among women and gender diverse people in Canada.
Methods
Framework
We drew on Graham et al's Knowledge-to-Action Framework to guide the translation of knowledge into actionable tools to influence health outcomes. 48 This framework contains three knowledge creation phases and seven action cycle phases. 48 Consistent with the approach used to develop the WCHC Model, we applied the three knowledge creation phases: (1) knowledge inquiry, (2) knowledge synthesis, and (3) product development; and two of the seven action cycle phases: (1) identifying the problem and reviewing and selecting knowledge and (2) adapting knowledge to the local context.44,48 These five phases were then packaged into three care model development steps 44 : (1) a formative phase with a rapid scoping review, environmental scan, and primary stakeholder interviews (knowledge inquiry and knowledge synthesis), (2) core team brainstorming to consider Step 1 findings and applicable W-PREV Model components (review and select knowledge), and (3) W-PREV Model development, revision and finalization (adapt knowledge to local context, product development) (Figure 1). These steps were used to collect empirical evidence and lived knowledge, providing a robust knowledge base for the adaptation of the WCHC Model to the W-PREV Model. The study was conducted from June 1st, 2024, to June 1st, 2025.

Packaging of five phases of the knowledge-to-action framework into three care model development steps.
Step 1: Formative Phase with a Rapid Scoping Review, Environmental Scan, and Primary Stakeholder Interviews
Rapid Scoping Review
Following the five-stage framework developed by Arskey and O’Malley, we conducted a rapid scoping review to identify effective and integrated HIV/STBBI prevention and SRH promotion programs for women. 49 The review generated actionable evidence to inform the development of the W-PREV Model. 50 The process involved defining the research question, identifying and selecting relevant studies, charting the data, and summarizing the findings. Our searches aimed to answer the question “What literature exists on HIV/STBBI prevention and SRH promotion programs and strategies for women globally?” Three members of the research team conducted the review. Screening and data extraction followed the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines (Appendix 1). 51 Eligibility criteria were developed using the Population, Concept, and Context (PCC) framework. 52
A systematic search of MEDLINE (2009–2024) was conducted with support from a health sciences librarian knowledgeable in scoping reviews. 53 Keyword searching was conducted to ensure extensive coverage of the research topic. Search terms included “HIV,” “sexually transmitted and blood-borne infections,” “prevention,” and “women's health”. 54 To broaden coverage, reference lists of included studies were screened using snowball sampling, and key journals were hand-searched to identify relevant grey literature. Inclusion criteria were refined iteratively as familiarity with the literature increased and focused on studies describing or evaluating HIV/STBBI prevention and SRH promotion interventions for women. Articles were required to be published in English between 2009 and 2024. Our searches identified 754 studies, and the grey literature produced an additional 5 studies. One member of the research team screened study titles and abstracts for relevance to the research question, retaining 107 studies for full-text review. Three members of the research team then independently applied the inclusion criteria to the 107 remaining studies, and 24 were included (Figure 2). Data were charted in Excel and captured the study design, population, setting, and outcomes related to HIV/STBBI prevention and SRH integration (Supplemental Table S1).

Web-Based Environmental Scan
To assess the clinical contexts of HIV/STBBI prevention services in Ontario and Saskatchewan, we followed Inaganti et al's environmental scan protocol to systematically identify clinics providing these services from websites. 55 This protocol follows Shahid and Turin's five-step framework for environment scans: (1) defining the purpose and objectives; (2) engaging key stakeholders; (3) refining the focus based on feedback; (4) gathering data comprehensively; and (5) sharing the findings. 56 This environmental scan protocol addressed the question “what HIV/STBBI prevention options are currently available in clinical settings in Ontario and Saskatchewan, and to what extent are these options integrated with services specific to women's needs?” Detailed methods are described elsewhere. 55
Clinics publicly listing HIV/STBBI services on their websites were identified in Ontario (n = 197) and Saskatchewan (n = 16). We then selected those explicitly offering HIV/STBBI prevention (eg, HIV self-testing, in-house testing, PrEP/PEP prescribing), resulting in 142 clinics offering HIV prevention and 166 offering STBBI prevention in Ontario and 8 clinics offering HIV prevention and 15 offering STBBI prevention in Saskatchewan. Data were extracted into a REDCap database, capturing clinic location, scope of care, and services addressing women's needs. Data were analyzed in Excel to examine the distribution, availability, and accessibility of HIV/STBBI prevention services. To contextualize clinic availability relative to regional population size, population data were obtained from publicly available provincial sources.57,58
Primary Stakeholder Interviews
We conducted qualitative interviews in Ontario and Saskatchewan to identify prevention needs, service gaps, and implementation considerations and to co-develop care model components responsive to community priorities. Recruitment occurred via an approved email to community-based organizations that serve women and gender diverse people with lived/living experience. These organizations then recruited participants for the primary stakeholder interviews. A separate approved email was sent to physicians/registered nurses and service providers. Eligibility was screened prior to participation. Interviews were completed (individual and group; in person or via Zoom, per participant preference) by two members of the research team. Demographic surveys were administered before the interview and were captured in REDCap. Guided by the Consolidated Framework for Implementation Research (CFIR) and the rapid qualitative analysis approach described by Nevedal et al, we used semi-structured guides tailored to either (1) women with lived/living experience or (2) clinicians/service providers (Appendix 2). 59 Each guide mapped questions to relevant CFIR domains and constructs while allowing conversational flexibility. Interviews with women with lived/living experience were done separately from interviews with clinicians/service providers. All interviews were audio recorded but not transcribed. 59 Two members of the research team took detailed notes during interviews, which were used to complete a structured summary template aligned with relevant CFIR domains and constructs. They then cross-reviewed one another's summaries and audio recordings to ensure consistency. Weekly meetings were held to compare interpretations, refine templates, and discuss emerging themes. Completed summaries were compiled into a comparative Excel matrix, enabling rapid synthesis of key barriers, facilitators, and implementation considerations that informed the W-PREV Model.
Step 2: Core Team Brainstorming to Integrate Step 1 Findings and Applicable W-PREV Model Components
Following the completion of Step 1 activities, findings from the rapid scoping review, environmental scan, and primary stakeholder interviews were presented to the core research team during a virtual meeting. An in-depth discussion followed to propose the initial components and structure of the W-PREV Model. Components of the model were based on the elements of the WCHC Model and key messages identified in the rapid scoping review and stakeholder interviews, and quantitative evidence from the environmental scan. Through iterative discussion, the team examined how evidence and lived experience could be translated into actionable, context-specific components of the W-PREV Model.
Step 3: W-PREV Model Development, Revision and Finalization
The first draft of the W-PREV Model was presented to external experts during a virtual meeting in early 2025 and circulated for detailed feedback. External reviewers comprised an interdisciplinary, anti-oppressive, and community-based panel to ensure that the model reflected the diverse HIV/STBBI prevention and SRH needs of women in Ontario and Saskatchewan. The model was subsequently shared at a national scientific meeting, allowing further feedback from researchers, clinicians, and community members. Suggestions from both stages of feedback were integrated into a refined version of the W-PREV Model—a trauma-informed, women-centred model of care designed to address gaps in HIV/STBBI prevention and SRH promotion for women.
Ethical Approval and Informed Consent
The study was approved by the Women's College Hospital's Ethics Assessment Process for Quality Improvement Projects (APQIP) (APQIP #: 2024-0040-P). All participants provided written informed consent prior to enrollment in the study.
Results
Rapid Scoping Review
Twenty-four articles met the inclusion criteria (Supplemental Table S1). The majority of primary studies were conducted in the United States (n = 5), South Africa (n = 5), Canada (n = 2), and Australia (n = 2). Most interventions were delivered in community-based or clinical settings (eg, primary care centers, community clinics, and hospitals). Interventions were primarily targeting culturally or ethnically specific populations, including African, Caribbean, and Black, Indigenous, and South Asian women, and sexual minority groups such as lesbian, bisexual, and queer women. Participants were predominantly adolescent girls and young women, though several studies also included women across broader age ranges and populations at increased risk for HIV/STBBIs, including sex workers, women who use substances, and refugee populations. Of the included studies, 13 were quantitative, comprising 5 pre–post quasi-experimental studies, one cross-sectional study, 1 cohort study, and 6 randomized controlled trials. Four were literature reviews, 4 used mixed-methods designs, and 3 were qualitative studies, comprising 1 descriptive, 1 secondary data analysis, and 1 grounded in community-based participatory research.
Our analysis of the included studies revealed three overarching themes (Figure 3). First, normalizing sexuality and sexual health in clinical care has been linked with decreased fear in women in raising sexual health topics with providers.60–62 Integrating non-blaming and non-judgmental “safety tips” and resources within regular appointments supports the destigmatization and standardization of HIV/STBBI discussions within care, dismantles power dynamics, eases fear of disapproval, and facilitates positive sexual health practices.60,62 Second, access to HIV/STBBI prevention and SRH information and personal care items in non-clinical settings (eg, in community-based organizations and programs for women and girls) offers innovative opportunities to link key populations to resources and engage novel stakeholders in sexual health promotion.63,64 Community-based spaces have also been seen to foster trust and safety, facilitating empowerment-focused prevention.65–67 This approach has led to increased awareness and uptake of public health measures, like HIV self-testing.68,69 Third, engaging key influencers (eg, community leaders and care providers) in HIV/STBBI prevention and SRH discussions and knowledge sharing can disrupt community-level stigma to create sustained changes.70,71 Building social and cultural acceptance can reduce stigma and facilitate positive health behaviors. 72 These themes indicate the need for a multi-level and integrated clinical and social approach to HIV/STBBI prevention for women.

Web-Based Environmental Scan
The environmental scan assessed the availability and scope of HIV/STBBI prevention services in Ontario and Saskatchewan, revealing substantial variation and systemic gaps (Figure 3). The analysis showed limited comprehensiveness among clinics offering HIV/STBBI services in both provinces. While some clinics provided HIV/STBBI care, such as antiretroviral therapy, many did not offer prevention services. In Ontario, fewer than three-quarters (n = 142, 72.1%) of identified HIV/STBBI service clinics offered HIV prevention, compared to only half in Saskatchewan (n = 8, 50.0%). A higher proportion of clinics provided STBBI prevention services (n = 166, 84.3% in Ontario and n = 15, 93.8% in Saskatchewan). Laboratory-based HIV testing was the most common form of prevention offered in both provinces (Ontario: n = 65, 45.8%; Saskatchewan: n = 5, 62.5%) (Tables 1a and 1b).

Among clinics providing HIV prevention, just over half in Ontario (n = 87, 61.3%) and three-quarters in Saskatchewan (n = 6, 75.0%) offered women-specific services, such as contraception and abortion care, trauma and violence support, and peer-led or empowerment programs (Tables 2a and 2b).

Furthermore, HIV prevention services were heavily concentrated in urban centres. For instance, Toronto had 1.52 clinics per 100,000 residents offering HIV prevention, while the South West health region had only 0.45 (Table 3a). 57 In Saskatchewan, regional disparities were even greater. The North Central West health region had 2.00 clinics per 100,000, while several northern and southern regions of the province had none (Table 3b). 58

In addition, there was a lack of clear, up-to-date information available on clinic websites. Details regarding the range of services, eligibility criteria, and access procedures were often incomplete or inconsistent, creating possible confusion for women seeking care. Many clinic websites contained broken links or were permanently closed, especially in rural and northern regions of the provinces.
Moreover, HIV prevention remains biomedically constrained, neglecting women's diverse experiences shaped by social determinants of health (SDH). Indeed, sociocultural contexts and perception of risk influence women's uptake and adherence to biomedically-framed HIV prevention methods (eg, PrEP, PEP, testing). 14 Among clinics offering HIV prevention, services that better acknowledge the structural and SDH, like HIV prevention counseling, education, and outreach, represented about one-fifth (n = 60, 19.1%) of services available in Ontario and one-tenth (n = 2, 11.8%) of services available in Saskatchewan. This indicates a lack of prevention efforts that can be tailored to women's needs. 73 However, clinics in Ontario (n = 62, 43.7%) and Saskatchewan (n = 5, 62.5%) also offered programs to reduce SDH-related barriers such as mental health counseling, housing and legal support, food and income assistance, newcomer and refugee programs, employment and education services (Tables 2a and 2b).
Similar findings were observed among clinics providing STBBI prevention. Testing was the most common service (Ontario: n = 133, 80.1%; Saskatchewan: n = 12, 80.0%) (Supplemental Tables S2 and S3). Women's services were available in a significant proportion of these clinics (Ontario: n = 120, 72.3%; Saskatchewan: n = 12, 80.0%) (Supplemental Tables S4 and S5). Services that aim to reduced SDH-related barriers were available at less than half of clinics (Ontario: n = 66, 39.8%; Saskatchewan: n = 6, 40%). Clinic distribution was again clustered in urban and northern regions—particularly in the Northern health region (1.95 per 100,000) and Toronto (1.32 per 100,000) in Ontario, and in the North Central West health region (2.00 per 100,000) and Saskatoon (1.48 per 100,000) in Saskatchewan (Supplemental Tables S6 and S7).57,58
Primary Stakeholder Interviews
Interviews were conducted with a total of 42 participants, including 24 women with lived or living experience and 18 clinicians or service providers. Most women with lived/living experience were between 40 and 50 years of age (n = 9, 38.0%) and also identified as people who use drugs (n = 16, 27.0%), sex workers or clients of sex workers (n = 13, 22.0%), and primarily resided in Toronto (n = 19, 68.0%) (Table 4a). The majority of the women with lived/living experience never accessed sexual health services through community-based settings (n = 7, 30.0%). Further, the majority of women with lived/living experience accessed sexual health services less than once a year (n = 6, 26.0%) or 1–2 times a year (n = 6, 26.0%) in clinical/medical settings.

Clinicians and service providers were typically between 30 and 49 years of age (n = 12, 67.0%), most often registered nurses (n = 4, 22.0%), and half were based in Toronto (n = 9, 50.0%) (Table 4b). They primarily work with people living with HIV or hepatitis (n = 13, 10.0%), trans, nonbinary, and gender diverse individuals (n = 14, 11.0%), racialized communities (n = 13, 10.0%), and people who use drugs (n = 13, 10.0%).
Thematic analysis of stakeholder interviews revealed several interconnected insights (Figure 3). Women with lived/living experience and clinicians/service providers emphasized that structural and systemic challenges—such as housing and income insecurity, limited mental health services, and racism—remain major barriers to HIV/STBBI prevention and SRH care. Many women with lived/living experience described how meeting basic needs must take precedence over preventive health, illustrating the urgency of addressing SDH within HIV prevention frameworks. Women with lived/living experience also expressed a strong desire for community connection, particularly among women at risk of HIV/STBBIs. These connections took many forms, from Indigenous women's healing through land, culture, and community to informal peer networks that shared information and supported navigation through complex systems of care.
Women with lived/living experience and clinicians/service providers highlighted the need to integrate SRH and HIV/STBBI services to minimize fragmentation across reproductive health, sexual health, and social support systems. This integration was viewed as critical to reducing missed opportunities for care and ensuring holistic, women-centred services. Several women with lived/living experience also shared that informal and accessible environments, such as drop-in centres, women's shelters, or peer groups, provided safe and trusted spaces for discussing HIV prevention. This highlights the need for HIV/STBBI prevention to extend beyond clinical settings. In addition, some women with lived/living experience began discussing PrEP, PEP, and DoxyPEP during group interviews, and many had never heard of these options before. Participants’ immediate interest in sharing this information with peers underscored the value of embedding prevention education within community-based and peer-led settings. Finally, sustainability emerged as a central concern from both women with lived/living experience and clinicians/service providers. Women with lived/living experience called for long-term, community-anchored approaches that ensure continued support and resources beyond the duration of individual studies or funding periods.
The W-PREV Model
The W-PREV Model evolved into the shape of a flower, with HIV/STBBI prevention and care at the centre and the petals symbolizing the interconnected domains of health that must work together to support the full health of women and gender diverse people (Figure 4). Each petal represents a key health delivery domain that would enhance HIV/STBBI prevention and care for women: (1) SRH care, (2) gender-specific care, including women's health care and gender-affirming care, (3) mental health care, (4) substance use care and harm reduction, (5) social connection and peer support, and (6) individual capacity building. Also essential to address, as represented by the stem and leaves, are social and biological determinants of health. The flower is nourished by the soil to represent that care must be grounded in trauma- and violence-aware, person-centred, and culturally responsive principles. The W-PREV Model uniquely applies these domains to HIV/STBBI prevention and early intervention, rather than treatment and ongoing care, and was developed directly from our environmental scan and stakeholder analyses that identified persistent prevention gaps across SRH, community supports, and system navigation.

The W-PREV model. The model includes trauma- and violence-aware care, person-centred care and culturally responsive care. The stem and leaves of the flower represent social and biological determinants of health to serve as the foundation. Each petal represents a key health delivery domain that would enhance HIV/STBBI prevention and care for women: (1) sexual and reproductive health care, (2) gender-specific care, including women's health care and gender-affirming care, (3) mental health care, (4) substance use care and harm reduction, (5) social connection and peer support, and (6) individual capacity building. PrEP (pre-exposure prophylaxis); PEP (post-exposure prophylaxis).
Several frameworks underpin the W-PREV Model, with a focus on trauma- and violence-aware care (TVAC), person-centred care, and cultural responsiveness. The model is foremost grounded in TVAC, acknowledging that many women who may be at risk of acquiring HIV/STBBIs have intersecting oppressions that may have resulted in experiences of violence or trauma in their lives. In our analyses, trauma and violence repeatedly emerged as barriers to prevention engagement and early care-seeking. Therefore, integrating TVAC into W-PREV serves a preventative function by fostering trust and access before HIV/STBBIs occur. TVAC is similar to trauma-informed care (TIC) in that it aims to deliver care with an understanding that interpersonal violence and violent victimization deeply impact one's life, health and development.44,74 TVAC and TIC both assert that providers should attempt to dismantle power dynamics in the care environment to give the patient a sense of control and empowerment in their care and to prevent re-traumatization.44,74 Both frameworks strive to create safe health care environments that recognize patients’ lived experience and honor their resilience.44,74 TVAC is grounded in anti-oppressive, anti-colonial and harm-reductive principles, requiring providers to recognize the enduring impacts of settler colonialism and colonial violence, especially on Indigenous Peoples’ health. 44 Still, TVAC extends on TIC by considering that “providers are not required to be experts in trauma and violence resolution, which may be implied in the term trauma-informed.” 44 Employing the W-PREV Model, providers will intentionally create space for women to be heard and their choices respected, actively resisting the perpetuation of institutionalized violence. 44
Our findings highlighted that prevention requires proactive and longitudinal engagement, shared decision-making around SRH and PrEP, and reduced care navigation barriers. These key gaps are incorporated directly into the W-PREV Model design. Person-centred care is a well-established approach with four key principles: (1) care grounded in empathy, trust, and provider competence; (2) shared decision-making and mutual responsibility between patient and care providers; (3) recognition of patient's lived experiences, expertise, and preferences; and (4) attention to the full spectrum of factors shaping health—including biological, psychological, cultural, familial, and socio-structural dimensions.44,75–77 Person-centred care affirms a woman's right to autonomous decision-making over her life, health, and care, but should also provide culturally-aware support, facilitating informed and confident decisions.44,75–77 Person-centred care also upholds that a woman's priorities/vulnerabilities will change over her life course, and having a reciprocal relationship with a care provider eases navigation through these shifts. 78 The W-PREV Model intends to holistically examine a woman's needs, providing them with a guided and personalized action plan for longitudinal behavioral change. Further, a part of person-centred care is relational practice in health that aims to establish and maintain strong relationships and trust between patients, providers, and communities, through which positive health and well-being can be achieved.79,80
The focus on cultural responsiveness is prevention-driven, addressing the mistrust, stigma, racism, and exclusion that our analyses identified as major barriers to accessing HIV/STBBI prevention and SRH services. Culturally responsive care recognizes that women and gender diverse people's experiences of health, illness, and care are shaped by their intersecting social positions, histories, and relationships with colonial and institutional systems.81–84 The W-PREV Model integrates cultural responsiveness and the concept of intersectionality as guiding values and as practice approaches, ensuring that HIV/STBBI prevention and SRH services are not only accessible, but also affirming, relevant, and respectful of diverse positions, identities, and ways of knowing and healing. Culturally responsive care begins with knowledge and understanding of women's voices, values and viewpoints. It aims to draw on community-based customs and embed cultural safety within every interaction. This means creating space for traditional knowledge, language, and spirituality; acknowledging the intergenerational effects of racism, colonization, and gender-based violence; and creating a reciprocal dynamic with women.
Like the WCHC Model, the W-PREV Model is developed for flexibility in its delivery (eg, single or multiple providers, interdisciplinary clinics, community organizations) and settings (eg, urban, rural), with a focus on alleviating the burden of system navigation from women's responsibility. While the W-PREV Model was developed within the Canadian context, flexible delivery facilitates the tailoring of our findings within different income and resource settings. At a minimum, a community must have access to a single coordinated space where clinical (ie, HIV/STBBI testing), community, and social services can be accessed. The W-PREV Model extends the WCHC Model by applying similar principles specifically to HIV/STBBI prevention, grounded in the gaps and needs identified through our scoping review, environmental scan, and stakeholder interviews.
Discussion
The development of the W-PREV Model was directly informed by the integrated findings of the rapid scoping review, environmental scan, and stakeholder interviews. Together, these activities highlighted major gaps in Canada's HIV/STBBI prevention landscape, specifically the dominance of biomedical approaches and the lack of attention to women's lived realities and SDH. Guided by Graham et al's Knowledge-to-Action Framework, we synthesized empirical evidence and community-based insights to adapt the WCHC Model into a prevention-focused framework responsive to women's needs. The resulting W-PREV Model highlights the need for a comprehensive, integrated, and women-centred approach that addresses the interdependence of structural, social, and clinical determinants of health. Like the WCHC Model, it integrates all components of holistic care—including SRH care, gender-specific care, including women's health care and gender-affirming care, peer support and social connection, mental health care, substance use and harm reduction, individual capacity building, and HIV/STBBI prevention and care as its central focus.
HIV/STBBI prevention strategies for women must extend beyond clinical settings and be embedded within community and social contexts. Within the W-PREV Model, this approach is operationalized through the integration of peer support and social connection as central components. These peer- and community-based spaces foster trust and safety, creating opportunities to normalize conversations around sexuality, where providers proactively and routinely discuss sexual health, dismantle power imbalances, and shift prevention from being risk-focused to empowerment-focused.65–67 Evidence from diverse populations, such as women who inject drugs, have shown that integrating SRH and HIV prevention in community outreach settings increases SRH service acceptability, uptake, and is predominantly preferred. 85 Similarly, among providers and Black adolescent young girls and women, there is a strong desire to normalize sexual health conversations to reduce stigma and overcome their own biases regarding risk. 86
The W-PREV Model reframes HIV/STBBI prevention as a holistic and empowerment-based process that situates women's experiences, relationships, and contexts at the center of care. Rather than viewing prevention as a series of biomedical interventions, the model recognizes it as part of a continuum that must integrate SRH care, harm reduction, mental health, and social support. Evidence consistently demonstrates that integrating HIV prevention within broader SRH and social-determinant–focused services leads to better outcomes, such as increased HIV and sexual health knowledge, condom use self-efficacy, and risk reduction intentions.85,87–93 Studies have similarly shown that integrated models of care are associated with higher HIV counseling and testing rates, increased uptake of sexual health services, and reduced stigma among women and female sex workers.88,89,92,94 Existing prevention efforts are often fragmented and focused in urban areas, leaving women in rural and northern regions—particularly Indigenous, racialized, and marginalized women with limited access to gender-responsive and culturally safe services. Women in rural and northern communities experience compounded disadvantages due to intersecting factors: limited health infrastructure, poverty, and social stigma.95,96 These factors restrict access to HIV prevention, testing, and treatment services, resulting in lower PrEP awareness and uptake, and less frequent provider-patient communication about HIV prevention options.97–99 The lack of nearby, integrated HIV and sexual health services forces women and gender diverse people in rural and northern areas to rely on general healthcare systems that are often overstretched and lack HIV-specific expertise or gender-responsive care, thereby limiting access to tailored prevention and support and reinforcing existing health inequities.96,100,101 An integrated, equitable, and adaptable approach to HIV/STBBI prevention—preferably delivered through a single, coordinated space of care where clinical, community, and social services are interconnected is needed. The W-PREV Model was designed to respond directly to these gaps by bridging clinical and community settings, integrating SRH, HIV/STBBI prevention, and social supports, and ensuring that care remains flexible, women-centred, and accessible across diverse geographic and social contexts.
The structural realities, such as racism, gender-based violence, and economic insecurity, reinforced that HIV/STBBI prevention cannot be achieved without addressing broader social and structural determinants of health. For many women, barriers such as poverty, housing and income instability, and lack of access to mental health supports often take precedence over preventive HIV health care.102–105 These findings affirm the W-PREV Model's foundation in the SDH and intersectionality and its integration of mental health, substance use, and harm reduction as essential domains. In this way, the W-PREV Model addresses the underlying conditions that shape prevention engagement, consistent with evidence showing that women's ability to access HIV prevention depends on addressing determinants of well-being.106–108
Limitations
It is important to address that some communities may not have access to the basic care required to deliver the W-PREV Model. The model was developed within the Canadian context, specifically Ontario and Saskatchewan, and may require adaptation in regions with differing health systems, resources, or sociocultural environments. Second, the evidence base informing W-PREV draws on a rapid scoping review, environmental scan, and stakeholder interviews. Although these methods provided timely and contextually rich insights, they may not fully capture the experiences of women with limited system engagement, such as those in rural, remote, or under-resourced communities. Further, we used a rapid qualitative analysis approach for the stakeholder interviews. Without transcription, it is possible that not all experiences of interview participants were captured in our analyses, despite iterative revision of recordings and facilitator notes. Additionally, the model has not yet been quantitatively evaluated for effectiveness or reach, and implementation will require cross-sector collaboration, stable funding, and policy alignment to prevent fragmentation. In March 2026, the W-PREV Model will be operationalized into a community-based intervention in Ontario. Metrics from this pilot study will provide insights on the feasibility and sustainability of W-PREV Model implementation. Lastly, while the flower-shaped design of the W-PREV Model serves as an accessible and symbolic representation of its interconnected domains, it may not resonate with all women and will need to be further refined through user feedback and evaluation.
Conclusions
The W-PREV Model represents a collection of knowledge from a rapid scoping review, environmental scan and interviews with women with lived/living experience and clinicians/service providers. Our goal is to genuinely respond to the needs of women and gaps in care, facilitating an urgent shift in HIV/STBBI prevention and SRH care for women in Canada. By linking HIV/STBBI prevention and SRH services with broader supports like mental health, housing, and peer supports, the W-PREV Model offers a solution that moves beyond the current biomedical approaches to HIV/STBBI prevention that produce barriers for women. The W-PREV model affirms women's agency and integrates the wisdom they have in their experiences, prioritizes flexibility and accessibility, and emphasizes individualized action planning for long-term health improvement. Further, the W-PREV Model is constructed so it may be tailored to diverse local contexts. Additional work is being done to operationalize the W-PREV Model into an adaptable, integrated, community-based intervention, consisting of operational sites, clinicians, community-outreach workers, training programs, and a needs assessment tool. The long-term aim is to integrate W-PREV within existing health and community-based programs in Canada, rather than delivering it as a standalone initiative. This includes building local capacity through peer-led care model delivery and a train-the-trainer strategy to reduce reliance on the research team over time, ensuring sustainability. A toolkit is also being developed to provide clear direction on how the W-PREV Model may be employed at various settings.
