Nurses working within secure psychiatric services spend a lot of time with mentally disordered in-patients. As a result, they need to acquire diverse skills to enable them to provide effective care for some of the most difficult patients. Their relationship with the individual, their observations, and ongoing assessments, are important to patient management and treatment. There is a need to achieve a balance between therapeutic intervention and security within secure psychiatric settings. The attitude of nursing staff towards their patients is of crucial importance in achieving a safe, therapeutic environment. Respect, tolerance, and non-judgmental attitudes are needed. A continuum of care is described, from initial assessment to aftercare in the community. The role of forensic nursing has evolved over the past decade.
