To examine the perspectives of people aged 80 years or older who self-harmed regarding their reasons for self-harm and its consequences, and their perceptions of care. A qualitative study using in-depth interviews. Participants were recruited from two teaching hospitals and associated community services. People aged 80 years or older who had self-harmed within the previous month. Structured psychiatric assessment including cognitive testing, DSM-5 diagnosis, and an in-depth qualitative interview focusing upon the reasons for and consequences of self-harm. Narrative enquiry was used to guide the discussion. All interviews were undertaken by a geriatric psychiatrist, audio recorded, transcribed verbatim, and subjected to thematic analysis using N-VIVO. Themes that emerged for the reasons for self-harm included "enough is enough"; "loneliness"; "disintegration of self"; "being a burden"; "cumulative adversity"; "hopelessness and endless suffering"; "helplessness with rejection"; and "the untenable situation". Themes for the consequences of self-harm were "becoming engaged with or distanced from family"; "the problem was solved"; "gaining control"; "I"m worse off now"; "rejection by health professionals"; and "tension in the role of the inpatient clinical environment". Self-harm may communicate a need that cannot otherwise be expressed. An individualized person-centered approach is required to respond to self-harm, including a combination of practical, medical, and psychological approaches as indicated. Involvement of families in the process of understanding the meaning of and responding to self-harm through education and family therapy, as well as education of healthcare professionals beyond risk factor notation may be indicated.
