High costs of intensive care as well as quality of care and patient safety demand measurement of nursing workload in order to determine nursing staff requirements. It is also important to be aware of the factors related to high patient care demands in order to help forecast staff requirements in intensive care units (ICUs).
To describe nursing workload using the Nursing Activities Score (NAS); to explore the association between NAS and patients variables, i.e. gender, age, length of stay (LOS), ICU discharge, treatment in the ICU, Simplified Acute Physiology Score II (SAPS II) and Therapeutic Interventions Scoring System-28 (TISS-28).
NAS, demographic data, SAPS II and TISS-28 were analysed among 200 patients from four different ICUs in a private hospital in São Paulo, Brazil.
NAS median were 66.4%. High NAS scores (> 66.4%) were associated with death (p-value 0.006) and LOS (p-value 0.015). Logistic regression analysis demonstrated that TISS-28 scores above 23 and SAPS II scores above 46.5 points, classified as high, increased 5.45 and 2.78 times, respectively, the possibility of a high workload as compared to lower values of the same indexes.
This study shows that the highest NAS scores were associated with increased mortality, LOS, severity of the patient illness (SAPS II), and particularly to TISS-28 in the ICU.
重症监护的高成本以及护理质量和患者安全要求对护理工作量进行测量，以确定护理人员需求。了解与高患者护理需求相关的因素对于帮助预测重症监护病房（ICU）的人员需求也很重要。
使用护理活动评分（NAS）描述护理工作量；探讨NAS与患者变量之间的关联，即性别、年龄、住院时间（LOS）、ICU出院情况、ICU治疗情况、简化急性生理学评分II（SAPS II）和治疗干预评分系统-28（TISS-28）。
对巴西圣保罗一家私立医院四个不同ICU的200名患者的NAS、人口统计学数据、SAPS II和TISS-28进行了分析。
NAS中位数为66.4%。高NAS评分（>66.4%）与死亡（p值0.006）和住院时间（p值0.015）相关。逻辑回归分析表明，TISS-28评分高于23分且SAPS II评分高于46.5分（均归类为高分），与相同指标的较低值相比，高工作量的可能性分别增加了5.45倍和2.78倍。
本研究表明，最高的NAS评分与死亡率增加、住院时间延长、患者疾病严重程度（SAPS II）相关，尤其是与ICU中的TISS-28相关。
