Recent research has highlighted that the number of people impacted by a death by suicide is far greater than previously estimated and includes wider networks beyond close family members. It is important to understand the ways in which suicide impacts different groups within these wider networks so that safe and appropriate postvention support can be developed and delivered. A systematic review in the form of a qualitative research synthesis was undertaken with the aim of addressing the question ‘what are the features of the experiences of workers in health, education or social care roles following the death by suicide of a client, patient, student or service user?’ The analysis developed three categories of themes, ‘Horror, shock and trauma’, ‘Scrutiny, judgement and blame’, and ‘Support, learning and living with’. The mechanisms of absolution and incrimination were perceived to impact upon practitioners’ experiences within social and cultural contexts. Practitioners need to feel prepared for the potential impacts of a suicide and should be offered targeted postvention support to help them in processing their responses and in developing narratives that enable continued safe practice. Postvention responses need to be contextualised socially, culturally and organisationally so that they are sensitive to individual need.
