Rapid recognition and treatment of myocardial infarction (MI) reduces morbidity and mortality. Although emergency department (ED) nurses are often the first provider to evaluate individuals and are in a prime position to initiate MI guideline recommendations, no valid and reliable instrument was found to quantify their decision-making processes. The purpose of this study was to develop and test the psychometric properties of a new theoretically driven, empirically based instrument for measuring nurses' cardiac triage decisions. Using a descriptive research design, data were collected using a mailed survey. There were 158 ED nurses who completed a mailed questionnaire. Factor analysis revealed three factors (patient presentation, unbiased nurse reasoning process, and nurse action) with good internal consistency (Cronbach's alpha = .903, .809, .718) and sample adequacy (KMO = .758) of the 30-item instrument. The newly developed instrument has the potential to improve patient outcomes surrounding early MI identification and treatment.
心肌梗死（MI）的快速识别与治疗可降低发病率和死亡率。尽管急诊科（ED）护士通常是评估患者的首位医疗人员，且处于启动MI指南建议的有利位置，但尚未发现有效且可靠的工具来量化他们的决策过程。本研究的目的是开发并测试一种新的、基于理论驱动和实证依据的工具，以测量护士的心脏分诊决策的心理测量特性。采用描述性研究设计，通过邮寄调查收集数据。共有158名急诊科护士完成了邮寄问卷。因子分析揭示了三个因子（患者表现、无偏见的护士推理过程和护士行动），该30项工具具有良好的内部一致性（Cronbach's alpha = .903、.809、.718）和样本充足性（KMO = .758）。新开发的工具具有改善早期MI识别和治疗方面患者预后的潜力。
