While forensic healthcare is a highly specialised area of clinical practice, many learning disability nurses will, over the course of their careers, be required to provide care to people who have had contact with the criminal justice system. Robust risk assessment and risk management systems are central to ensuring the well-being and safety of people with learning disabilities who have forensic needs. Although the core assessment skills required to undertake forensic risk assessments are embedded in nurses’ skill set, learning disability nurses need to develop their knowledge and understanding of how to apply these skills in forensic practice. This article explores the principles of forensic risk assessments and the elements of the forensic risk assessment process as a foundation to risk formulation. The author uses a fictitious case study to illustrate forensic risk assessment, risk formulation and the development of a tailored risk management plan.
