Inclusion health seeks to address severe health disparities faced by socially excluded populations, including people experiencing homelessness, substance use or marginalisation due to migration status or criminal justice involvement. Despite the growing need, access to appropriate and empathetic healthcare remains limited due to systemic barriers, stigma and service fragmentation. Outreach healthcare services, which bring care directly to individuals in their own environments, present a promising solution. A realist synthesis of multicomponent outreach programmes highlights key contextual and operational elements that support effective engagement and improved health outcomes for people experiencing exclusion in high-income countries.
Key Components of Effective Outreach
The success of outreach care hinges on thoughtful design, which includes flexible service models and active involvement of service users in the development process. Low-threshold eligibility, persistent outreach and the ability to tailor services to individual needs create a foundation of accessibility. Meeting immediate needs, such as providing food or shelter, and delivering care in environments that service users find familiar and safe help build trust. Trusted locations vary widely depending on personal history, social context or safety concerns, underscoring the importance of local input when determining where and how care should be delivered.
Appointment structures must reflect the realities of service users' lives. Flexible timings and drop-in models increase the likelihood of attendance. Shared decision making empowers users, creating a sense of ownership and increasing the chances of continued engagement. Providing care within the daily environment of service users helps staff better understand the conditions individuals face and improves the relevance and responsiveness of care. Confidentiality and anonymity, when ensured, further reduce barriers to disclosure and service engagement, especially in cases involving stigma or personal risk.

Relational Dynamics and Staff Approaches
The relationship between staff and service users is central to the success of outreach programmes. Respectful, non-judgemental communication, cultural humility and continuity of staff help build psychological safety and trust. Staff who consistently demonstrate empathy and follow through on promises foster long-term engagement, especially among individuals with past experiences of stigma or trauma within healthcare systems. Staff expertise must include the ability to adapt communication styles and demonstrate cultural sensitivity, which are crucial when working with diverse and marginalised groups.
Peer workers bring lived experience that helps bridge gaps between clinical staff and service users. Their involvement improves communication, builds trust and makes health messages more relatable. Despite their value, relatively few outreach services fully integrate peer workers in both the development and delivery phases. When included, their insights ensure service relevance and offer unique opportunities to promote understanding among staff and service users alike. Sustained investment in peer support, alongside appropriate training and support structures, is essential for this role to succeed.
Integration with Mainstream Services
While outreach plays a critical role in connecting with underserved populations, integration with mainstream services remains a necessary goal. Outreach staff often serve as trusted intermediaries, facilitating introductions to conventional care settings. Providing practical assistance, such as help with forms, transportation and interpreter services, can ease the transition into mainstream care. Working collaboratively with hospitals, primary care providers and social services enhances continuity and coordination. Clearly defined organisational roles and communication pathways improve care quality and reduce duplication or fragmentation.
Holistic service delivery within outreach programmes, where physical, mental and social health needs are addressed concurrently, reduces the need for multiple appointments and repeated disclosures. This model is particularly effective for individuals with complex needs who would otherwise struggle to navigate separate care systems. Co-locating services or providing care through integrated teams strengthens engagement and supports long-term health outcomes. However, the balance between offering comprehensive outreach and promoting integration must be carefully managed to avoid reinforcing separation from mainstream care.
Outreach services tailored to people experiencing exclusion can substantially improve healthcare access and engagement when built on trust, flexibility and user-centred design. The most effective models integrate respect, communication and continuity, while prioritising immediate needs and enabling long-term care planning. Peer support and service user involvement in design and evaluation enhance relevance and accountability. Importantly, outreach must not function in isolation; linking service users with mainstream care is vital for comprehensive health management and sustainability. Investment in skilled staff, appropriate infrastructure and inter-service collaboration is essential to support these models. When designed thoughtfully and delivered with empathy, outreach care can play a transformative role in promoting health equity and inclusion.
