Literature on variables relating to nursing structures, nursing support systems, and patient classification systems contains discrepancies in definitions and methods. This lack of systematic research results in uncertainty and renders comparisons untenable.
关于护理结构、护理支持系统和患者分类系统相关变量的文献在定义和方法上存在差异。这种缺乏系统性研究的情况导致了不确定性，使得比较变得难以成立。
