Patient conditions associated with the relative amount of time nurses spent caring for patients were identified in this study. The patient conditions examined were: nursing condition using 37 nursing diagnoses, medical condition using diagnosis-related groups (DRGs), and demographic characteristics of age, sex, and race. Nursing time was estimated using the Rush-Medicus patient classification workload measurement tool. Data were gathered from checklists of nursing diagnoses and the discharge records of 2560 adult inpatients of an acute care community hospital. Using multiple regression analysis nursing condition explained twice the variation in daily nursing workload (52.4%) than medical condition (26.3%). The finding that nursing care time is predicted better by a patient's nursing condition than by either medical condition or demographic characteristics indicates that nursing care is not physician prescribed.
本研究确定了与护士照顾患者的相对时间量相关的患者状况。所检查的患者状况包括：使用37种护理诊断的护理状况、使用诊断相关分组（DRG）的医疗状况以及年龄、性别和种族的人口统计学特征。使用拉什-梅迪克斯患者分类工作量测量工具估算护理时间。数据收集自护理诊断清单以及一家急性护理社区医院2560名成年住院患者的出院记录。通过多元回归分析发现，护理状况对每日护理工作量变化的解释力（52.4%）是医疗状况（26.3%）的两倍。患者的护理状况比医疗状况或人口统计学特征更能预测护理时间，这一发现表明护理并非由医生规定。
