Situation awareness may be used to operationalize nursing students' clinical judgment of patient deterioration simulation scenarios.
To develop and test an instrument to measure bachelor-level nursing students' situation awareness in a patient deterioration simulation scenario, using the Situation Awareness Global Assessment Technique (SAGAT).
Instrument development and validation.
A faculty of nursing of a French-Canadian university.
15 critical care experts and 234 bachelor-level nursing students from a critical care course.
The queries were developed from evidence and guidelines regarding nurses' assessment and response to patient deterioration and an inventory of nursing diagnosis. After expert content validation, the instrument was administered to three cohorts of nursing students in a high-fidelity simulation with a scenario of hypovolemic hemorrhagic shock. Difficulty, discrimination, and fidelity indices were computed. The impact of the instrument on student's performance was assessed with a post-simulation survey.
The instrument comprised 31 queries, which obtained high content validity indices. Most showed satisfying difficulty, discrimination, and fidelity properties. Inadequate properties of the queries may be explained by the content of the simulation scenario, the assessment practices of nursing students, and their reliance on medical assistance. Students perceived that completing the instrument helped them realize what they forgot to assess in the simulation.
This instrument appears as a promising research tool, although it still needs to be tested with other populations and in other patient deterioration simulation scenarios.
态势感知可用于将护理专业学生对患者病情恶化模拟场景的临床判断付诸实践。
使用态势感知全局评估技术（SAGAT）开发并测试一种工具，以测量本科护理专业学生在患者病情恶化模拟场景中的态势感知。
工具开发与验证。
一所法裔加拿大大学的护理学院。
15名重症护理专家和234名来自重症护理课程的本科护理专业学生。
这些问题是根据有关护士对患者病情恶化的评估和应对的证据及指南以及护理诊断清单制定的。经过专家内容验证后，该工具在高保真模拟中对三组护理专业学生进行了测试，模拟场景为低血容量性出血性休克。计算了难度、区分度和逼真度指标。通过模拟后调查评估该工具对学生表现的影响。
该工具包含31个问题，获得了较高的内容效度指标。大多数问题显示出令人满意的难度、区分度和逼真度特性。问题特性不足可能由模拟场景的内容、护理专业学生的评估实践以及他们对医疗援助的依赖来解释。学生们认为完成该工具帮助他们意识到在模拟中忘记评估的内容。
尽管该工具仍需在其他人群和其他患者病情恶化模拟场景中进行测试，但它似乎是一个有前景的研究工具。
