Seen as Core: A Delphi Consensus Study of Essential Elements of Mental Health Nursing Care in Ireland

Continued ambiguity about the scope of mental health nursing is harmful to the discipline's identity and to patients' interests. Using a Delphi survey design, consensus was achieved on a set of 70 items representing core elements of mental health nursing among a sample of 150 mental health nurses working in Ireland. Items achieving consensus in Round 3 of the survey were composed of 28 clinical phenomena (framed as client problems), 18 direct and 12 indirect nursing interventions, and 12 nursing-sensitive outcomes of care. Mental health nurses accepted responsibility across a broad range of outcomes apart from those linked to physical care, the one domain of care rejected by participants. The findings portray mental health nursing as a psychosocial enterprise, encompassing both phenomenological and diagnosis-related elements.
