OBJECTIVES: Older adults bereaved by suicide face unique challenges, including heightened stigma, trauma, and isolation, often compounded by limited social support. This study explores professionals' perspectives on supporting older adults bereaved by suicide, addressing a critical gap in public health. METHOD: Semi-structured, in-depth interviews were conducted with professionals, including bereavement support workers, healthcare providers, and suicide prevention specialists. Data were analysed using a reflexive, inductive thematic approach. RESULTS: Four key themes emerged: (1) navigating the complexities of traumatic loss by suicide in later life, (2) the role of community and family support in grief management, (3) professional roles and challenges in providing support, and (4) opportunities for community engagement and meaning-making. Findings emphasise the need for community-centred, culturally sensitive bereavement care that empowers older adults to navigate grief openly. CONCLUSION: Reducing stigma around suicide, recognising the impact of traumatic loss, and addressing factors that exacerbate grief are crucial to supporting mental health in older adults bereaved by suicide. Integrating bereavement support into community spaces and offering peer-support options can help alleviate isolation and trauma. Health and social care policies should prioritise improving access to services and promoting an inclusive and trauma-informed approach that meets the unique needs of this population.
