To validate a model to estimate the nursing workload required by trauma victims on intensive care unit (ICU) discharge.
Identifying a reliable model of nursing workload measurement that can assist professionals.
A prospective cohort study conducted in 2010 (first phase) and 2015 (second phase) with 342 trauma victims admitted into the ICU of four hospitals located in São Paulo, Brazil. The original model was created during the first phase and included the Simplified Acute Physiology Score and New Injury Severity Score variables. Coefficients of determination (R ) were calculated to identify the reliability.
The original model presented high reliability (R = 44%) in the hospital of origin, and unsatisfactory performance (R < 4%) in the other institutions. An improvement in R was observed after adjusting the coefficients for each hospital.
For the Nursing Activities Score prediction of survivors for ICU discharge, trauma centres must validate the original model with coefficient adjustments for their population, or preferably derive their own models.
Although models are useful in predicting discharge of these ICU patients, for treatment continuity after critical care and for organising services, the study showed that they should be evaluated prior to use for nursing management.
验证一种用于估算创伤患者重症监护病房（ICU）出院时所需护理工作量的模型。
确定一种可靠的护理工作量测量模型，以协助专业人员。
2010 年（第一阶段）和 2015 年（第二阶段）进行了一项前瞻性队列研究，纳入了来自巴西圣保罗的 4 家医院的 342 名创伤患者。原始模型是在第一阶段创建的，包括简化急性生理学评分和新损伤严重程度评分变量。计算确定系数（R ）以确定可靠性。
原始模型在原籍医院具有较高的可靠性（R = 44%），而在其他机构的表现则不尽如人意（R < 4%）。对每个医院的系数进行调整后，R 值有所提高。
对于 ICU 出院的幸存者的护理活动评分预测，创伤中心必须针对其人群对原始模型进行调整系数验证，或者最好开发自己的模型。
虽然这些模型在预测 ICU 患者出院方面很有用，对于重症监护后的治疗连续性和服务组织，但研究表明，在用于护理管理之前，应先对其进行评估。
