Abstract

Aggression and violence remain persistent challenges in inpatient mental health services, with significant implications for patient safety, staff wellbeing, therapeutic relationships and the continued use of restrictive practices. Although de-escalation is widely promoted as a first-line, non-coercive response to distress and behavioural escalation, its implementation remains inconsistent and the evidence base is fragmented across relational, educational, organisational and policy literatures. This paper reports a structured critical narrative synthesis of United Kingdom-relevant empirical, theoretical, policy and practice literature examining de-escalation, staff training, restrictive-practice reduction and organisational responses to aggression and violence in adult inpatient mental health care. Literature published between January 2014 and March 2024 was identified through searches of Scopus, CINAHL, PubMed/MEDLINE, ProQuest and Web of Science, supplemented by reference-list screening and targeted grey-literature searches. Sources were selected for their relevance to adult inpatient mental health settings and their contribution to understanding how de-escalation is enacted, supported and sustained. Given the heterogeneity of the evidence, design-appropriate appraisal principles informed by the Critical Appraisal Skills Programme and Mixed Methods Appraisal Tool were used to support interpretation. The synthesis identified three interdependent domains shaping de-escalation practice: People, Capability and Context (PCC). Therapeutic relationships, communication, emotional intelligence and service-user involvement underpinned early recognition of distress and relationally attuned responses. Workforce capability was strengthened through simulation, reflective learning, team rehearsal and practice-proximal evaluation. Organisational context, including staffing, leadership, ward environment, safety culture, equity safeguards and wider structural determinants, shaped whether de-escalation could be enacted consistently and safely. These findings generated the PCC framework as a practice-facing model that conceptualises de-escalation as an emergent practice arising from alignment between relational processes, workforce capability and organisational conditions. The framework offers a practical basis for guiding restrictive-practice reduction, quality improvement, equity-sensitive monitoring and future empirical research in inpatient mental health care.
