目的 In recent years,violence against doctors in China highlights a widespread concern around the world.[1 2] However,violence against medical professionals seems to be common in many countries.[3] Cross-national comparison can shed light on this question.Violence is not unique in China In Australia,58％of general physicians(GPs)encountered verbal abuse and 18％of them encountered property damage,such as theft.Few of the GPs encountered physical violence,stalking,sexual harassment,at a rate of 6％,4％,6％and 0.1％respectively.[4] About half of doctors in the UK have experienced workplace violence,compared that a third of doctors in China.[3] However,Chinese doctors often experience tremendous life-threatening violence,.Furthermore,attacks are particularly occurred in emergency department,outpatient department and psychiatry throughout many countries.[5] In these sectors,patients have to endure a long wait,during which their anxieties,concerns and unrealistic expectations accumulate constantly.[3] In Australia,patients usually have to wait for 6 weeks at home before they get medical service.[4] This seems to be more serious in China,where patients often sleep in the corridor of hospital before making appointments with doctors.
