Forty-nine hospital wards in the United States and Canada were surveyed during specified periods for one year to document assaults by inpatients on staff or other patients. Nine (5.7%) of the 158 assaults by adult psychiatric inpatients were sufficiently severe to require medical treatment. Four others occurred on the only children's service studied. Only one (2.6%) of 39 assaults on adult nonpsychiatric units required medical care. Injuries were rarely serious, with only four assaults in any setting leading to bedrest or missed workdays. The overall rate of assault (assaults per bed per year) on 27 adult psychiatric units was 1.36; for assaults requiring treatment, the rate was 0.08. The rate of assault of any kind on 22 adult nonpsychiatric units was 0.28 assaults per bed per year.
在美国和加拿大，研究人员在特定时期内对49个医院病房进行了为期一年的调查，以记录住院患者对医护人员或其他患者的攻击行为。在158起成年精神科住院患者的攻击事件中，有9起（5.7%）严重到需要医疗救治。另外4起发生在唯一被研究的儿童科室。在成年非精神科病房的39起攻击事件中，只有1起（2.6%）需要医疗护理。受伤情况很少严重，在任何环境下只有4起攻击事件导致卧床休息或误工。27个成年精神科病房的总体攻击率（每年每张床位的攻击事件数）为1.36；对于需要治疗的攻击事件，该比率为0.08。22个成年非精神科病房的任何类型攻击率为每年每张床位0.28起攻击事件。
