1. The Historical, Clinical, Risk Management-20 (HCR-20) can be used reliably to assess the violence risk in discharged psychiatric patients.
2. Most violent outcomes can be predicted by the structured final risk judgement of the HCR-20 at 6 months but not at 12 months.
3. To improve violent risk assessment and management in Hong Kong, a structured evidence-based risk assessment instrument such as the HCR-20 is recommended for early detection of high-risk patients.
