BACKGROUND The link between schizophrenia spectrum disorders (SSD) and violence is a core issue for most forensic psychiatric services. However, the drivers of violence in this population remain unclear, and, to date tools to predict violence risk have a range of limitations. Perhaps because of this uncertainty about the nature of violence risk, treatment programmes and care pathways for mentally disordered offenders vary substantially across the European Union, and differences in legal and policy frameworks are highly relevant. METHODS The three-year EU-VIORMED project (Grant Number PP-2-3-2016, November 2017-October 2020) involves forensic centres in Italy, Austria, Germany, Poland, and the U.K. It aims to: (a) identify and compare violence risk factors, clinical needs, and decision making capacity in violent (N = 200, "cases") and nonviolent patients with SSD (N = 200; "controls") using a case-control design; (b) test the predictive validity of the HCR-20v3, OxMIS and FoVOx among cases alone (N = 200), using a prospective cohort study; and (c) compare forensic-psychiatric care pathways across the EU, in a continent wide service mapping study. DISCUSSION Data collection started in September 2018 and continues. By September 2019, 333 participants have been enrolled (201 cases and 132 controls were recruited). Experts from 23 countries provided data for the service mapping exercise. TRIAL REGISTRATION Retrospectively registered on January 2, 2019 as researchregistry4604 January 2, 2019.

欧洲暴力风险和精神障碍（EU-VIORMED）：一项多中心前瞻性队列研究方案。

背景精神分裂症谱系障碍（SSD）与暴力之间的联系是大多数法医精神病学服务的核心问题。然而，该人群暴力的驱动因素仍不清楚，而且迄今为止预测暴力风险的工具存在一系列局限性。也许由于暴力风险性质的不确定性，欧盟各地针对精神障碍罪犯的治疗方案和护理途径差异很大，而且法律和政策框架的差异也高度相关。方法 为期三年的 EU-VIORMED 项目（拨款号 PP-2-3-2016，2017 年 11 月至 2020 年 10 月）涉及意大利、奥地利、德国、波兰和英国的法医中心，其目的是：(a) 识别和使用病例对照设计比较暴力（N = 200，“病例”）和非暴力 SSD 患者（N = 200；“对照”）的暴力风险因素、临床需求和决策能力；(b) 使用前瞻性队列研究测试 HCR-20v3、OxMIS 和 FoVOx 在单独病例 (N = 200) 中的预测有效性；(c) 在一项全大陆服务地图研究中比较整个欧盟的法医精神病护理路径。讨论 数据收集于 2018 年 9 月开始并持续进行。截至 2019 年 9 月，已入组 333 名参与者（招募了 201 名病例和 132 名对照者）。来自 23 个国家的专家为服务映射工作提供了数据。试用注册于2019年1月2日追溯注册为researchregistry4604 2019年1月2日。
