当前时见一幕幕医患纠纷的惊心场景，一则则砍杀医生的报道见诸报章，可以说我国医生、护士正经历着一场前所未有的、全国性的三位一体的患者"安全危机"、"医师安全危机"和"医患关系"危机，引发着一系列严重后果。"暴力伤医"不仅给医生带来巨大的身体、心理伤害，影响医疗系统的服务供给能力，增加整体医疗费用支出，同时极易导致"自我保护性诊疗"及"弃医转行"，最终结果仍由整个社会埋单，目前急需在医院暴力影响因素及应对策略方面有所突破。本研究拟采用定量、定性相结合的方法，在现场调查和典型案例分析的基础上应用DEMATEL法通过从多维视角分析医院暴力的影响因素，量化分析和探索暴力行为发生的内在机制，挖掘其产生的根本原因，为应对"暴力伤医"事件从个人与组织两个层面提高针对此类突发事件应急能力的策略选择及有效干预措施提供实证依据。并在"破窗理论"指导下构建医院暴力的综合应对策略。

A series of bloody attacks on medical professionals in China triggers comprehensive crisis of doctor' safety, patients's safety, and the already deteriorating patient & doctors relationship, resulting in severe consequences: higher levels of anxiety, post-traumatic stress disorder, depression, self-protection medical treatment and intentions to quit.It costs hospitals untold millions in lost time, employee turnover, reputation for quality care, and additional security measures. Risk factor identification and prevention policy study for workplace violence (WPV) in health care workers has become an urgent need. This study will combine qualitative and quantitative methods to investigate health professionals' experiences with WPV in order to describe WPV by type, frequency, perpetrator, and contributing factors related to WPV that occur in general hospital settings. And will introduce Decision Making Trial Evaluation Laboratory (DEMATEL) to explore the relationship and mechanism between WPV and contributing factors from multidimensional perspective of medical, criminal, social and crisis management. Aim to provide empirical evidence for targeted prevention program and policy making. Then under guidance of Broken Window Theory hope we can formulate effective intervention strategies targeting WPV to protect health workers and provide safer hospital workplaces environment.
