To evaluate the mean nursing workload obtained through the Nursing Activities Score (NAS) and extract the degree of dependency of patients using Perroca's Patient Classification System (PCS).
Prospective study conducted at the intensive care unit of a private hospital that is a center of reference in oncology. The instruments were applied daily in a sample of 40 patients with a minimum stay of 24 hours.
Two hundred and seventy-seven measurements were performed with the instruments. The NAS mean was 69.8% (± 24.1%) and Perroca's Patient Classification System score was 22.7% (± 4.2%). The hours of care found by averaging NAS were almost twice those estimated by Perroca's, showing a difference of 7.3 hours.
The direct instrument NAS was more appropriate to measure nursing workload when compared to Perroca's indirect instrument in the studied intensive care unit.
通过护理活动评分（NAS）评估平均护理工作量，并使用佩罗卡患者分类系统（PCS）提取患者的依赖程度。
在一家作为肿瘤学参考中心的私立医院重症监护病房进行前瞻性研究。这些工具每天应用于40名患者的样本，患者最少住院24小时。
使用这些工具进行了277次测量。NAS平均值为69.8%（±24.1%），佩罗卡患者分类系统评分为22.7%（±4.2%）。通过平均NAS得出的护理小时数几乎是佩罗卡估计值的两倍，相差7.3小时。
在研究的重症监护病房中，与佩罗卡的间接工具相比，直接工具NAS更适合测量护理工作量。
