The association between nurse staffing and patient violence on psychiatric units is unclear, and the association between nursing skill mix and violence has not been studied. Monthly data on physical/sexual assaults by patients against others were obtained for 351 adult psychiatric units. Total and injury assault rates were modeled as dependent variables using hierarchical Poisson regression, with total staffing and registered nurse (RN) mix as predictors. Assault rates were 12% higher per additional nursing hour per patient day but 6% lower per 5-point increase in percent of hours provided by RNs. In cubic spline models fit to explore nonlinear staffing-violence associations, assault rates increased with staffing through most of its range but began to decline at very high levels.
护患比例与精神科病房的患者暴力行为之间的关系尚不明确，护理技能组合与暴力行为之间的关系也尚未得到研究。本研究每月收集 351 个成人精神科病房内患者对他人实施的躯体/性侵犯数据。采用分层泊松回归模型，以总护理人员配备和注册护士（RN）配比作为预测因子，将总侵袭率和伤害性侵袭率作为因变量进行建模。每增加每患者护理小时数 1 个护理小时，侵袭率增加 12%；每增加 5%的 RN 提供的护理时间，侵袭率降低 6%。在探索非线性护患比例-暴力行为关系的三次样条模型中，侵袭率在其大部分范围内随护理人员配备的增加而增加，但在非常高的水平时开始下降。
