背景：护士实践的组织背景对于解释患者结果的变化很重要，但由于缺乏经验测量组织属性的工具，研究受到阻碍。目的：报告修订护理工作指数（NWI-R）在衡量专业护理实践环境特征方面的发展和应用。方法：在一项全国获得性免疫缺陷综合征（AIDS）护理研究中使用NWI-R。样本包括20家医院的40个单位。在这20家医院中，有10家在专门的艾滋病部门和普通医疗部门提供艾滋病护理，从而在设计中引入了内部控制的因素。其余10家医院是通过配对程序选出的。匹配的对照医院中有3家为磁石医院。如果护士每周在研究单位工作至少16小时，他们就会被招募到研究中。除其他措施外，护士还完成了NWI-R。结果：有效率达86%。每单位的应答率从73%到100%不等。整个NWI-R的Cronbach's alpha为0.96，聚合子量表alpha为0.84 ~ 0.91。NWI-R的有效性通过该工具的起源、区分在专业实践环境中工作的护士和不在专业实践环境中工作的护士的能力以及解释护士职业倦怠差异的能力来证明。结论：NWI-R可以捕捉到专业护理实践环境的组织属性。
Background: The organizational context in which nurses practice is important in explaining variation in patient outcomes, but research has been hampered by the absence of instruments to measure organizational attributes empirically.Objectives: To report on the development and utility of the Revised Nursing Work Index (NWI-R) in measuring characteristics of professional nursing practice environments.Methods: The NWI-R was used in a national acquired immunodeficiency syndrome (AIDS) care study. The sample consisted of 40 units in 20 hospitals. Of these 20 hospitals, 10 provided AIDS care in both dedicated AIDS units and general medical units, thus introducing to the design an element of internal control. The remaining 10 hospitals were selected through a matching procedure. Three of the matched control hospitals were magnet hospitals. Nurses were recruited into the study if they worked at least 16 hours per week on the study unit. The nurses completed the NWI-R in addition to other measures.Results: A response rate of 86% was attained. Response rates per unit ranged from 73% to 100%. Cronbach's alpha was 0.96 for the entire NWI-R, with aggregated subscale alphas of 0.84 to 0.91. Validity of the NWI-R was demonstrated by the origin of the instrument, its ability to differentiate nurses who worked within a professional practice environment from those who did not, and its ability to explain differences in nurse burnout.Conclusion: The NWI-R has been found to capture organizational attributes that characterize professional nursing practice environments.
