Abstract
Abstract Tensions between therapeutic and security needs on forensic wards can create a social climate which is challenging for both mental health nurses and patients. Social climate refers to the physical, social and emotional conditions of a forensic ward which influence how these environments are experienced. For patients with borderline personality disorder (BPD), previous trauma means that the social climate of forensic settings may be experienced as retraumatising, negatively impacting the outcomes and wellbeing of both patients and mental health nurses. Trauma‐informed care (TIC) has been offered as a contemporary framework for mental health nursing in inpatient units which aims to create a therapeutic social climate. In this critical review, we drew widely on literatures examining the social climate in forensic settings, the relationships between patients with BPD and staff (including mental health nurses), and the experiences of patients with BPD in forensic and inpatient settings to draw out the implications of scrutinising these literatures through the lens of TIC. Attending to the physical, social and emotional conditions of social climate in secure settings highlights how forensic wards can mirror trauma experiences for patients with BPD. Implementing TIC in these contexts has the potential to evoke positive shifts in the social climate, thus reducing the risk of retraumatisation and leading to improved outcomes for patients and staff.
