Abstract
Abstract OBJECTIVE Verify if aging is an independent predictor of NW in ICU, according to age groups, and its predictive value as a determinant of NW in ICU. METHODS Study was conducted from 2012 to 2016. A convenience sample composed by patients (age ≥ 18) admitted to nine ICU belonging to a Brazilian hospital, was analyzed. Age was assumed as an independent variable and NW (measured by the Nursing Activities Score - NAS) as dependent. Linear regression model and ROC curve were used for the analysis. RESULTS 890 participants (361 older people), mostly males (58.1%). The mean NAS score was higher among older participants in comparison to adults (p=0.004) but not within categories of aging (p=0.697). Age was responsible for 0.6% of NAS score. Each year of age increases NAS score in 0.081 points (p=0.015). However, age was not a good predictor of NAS score (AUC = 0.394; p=0.320). CONCLUSION The care of older people in ICU is associated with an increase in NW, compared to adults. Aging can be considered an associated factor but not a good predictor of NW in ICU.
摘要 目的 根据不同年龄组，验证老龄化是否为重症监护病房（ICU）中护理工作量（NW）的独立预测因素，并评估其作为ICU护理工作量决定因素的预测价值。 方法 本研究于2012年至2016年开展。对巴西某医院9个ICU收治的患者（年龄≥18岁）组成的方便样本进行分析。将年龄作为自变量，护理工作量（采用护理活动评分[NAS]进行测量）作为因变量。采用线性回归模型和ROC曲线进行分析。 结果 共纳入890名受试者（老年人361例），多为男性（58.1%）。与非老年成年受试者相比，老年受试者的平均NAS评分更高（p=0.004），但在老年各亚组内部差异无统计学意义（p=0.697）。年龄解释了NAS评分0.6%的变异。年龄每增加一岁，NAS评分增加0.081分（p=0.015）。然而，年龄并不是NAS评分的良好预测指标（AUC = 0.394；p=0.320）。 结论 与非老年成年患者相比，ICU老年患者的护理与护理工作量的增加相关。老龄化可被视为ICU护理工作量的一个相关因素，但并非良好的预测指标。
