Suicide by hanging is increasing in many countries around the world and whilst efforts are being made to influence the prevention agenda to reduce the incidence, little is known regarding the contributing factors for choosing this method. The purpose of this scoping review is to summate understandings about how the epidemiology and prevention of suicide by hanging is recognised, described, and discussed in the literature, and critically appraise the extent to which the lived-experiences of survivors of suicide attempts are included. A scoping review was conducted implementing the appropriate framework and in accord with the PRIMSA-ScR extension. Three databases (CINAHL, PubMed, and PsycINFO) were searched along with the reference lists of eligible sources in January and February 2021. Thirty-six articles with a primary focus on hanging as a method of suicide and/or its prevention are included in this review, with brief thematic analysis used to summarise the featured studies. Three distinct themes emerging from the literature include: (i) Hanging suicide deaths in the community environment or person’s usual place of residence, (ii) Hanging suicide deaths in controlled environments (including police cells, prisons, and inpatient units), and (iii) Medical management of near-lethal hangings. This review highlights the necessity for improving education and policy regarding the controlled environments frequently associated with hanging suicides and the medical management of near-lethal hangings, as well as the ongoing need for policy to guide and govern the responsible media portrayal of known suicides as well as fictional hangings. Finally, this review highlights the necessity for including those with lived-experiences of a suicide attempt by hanging to advance the current prevention agenda.
