The development of decision-making models for emergencies is critical because emergencies can occur anytime and anywhere. This is because this situation requires quick and appropriate action. The purpose of this concept analysis is to analyze and clarify the concept of decision makers in the scope of emergencies and develop an operational definition of the concepts of decision makers, attributes, antecedents, and consequences. The method used is the concept analysis approach of Walker and Avant. The results of the analysis show that the attributes of the concept of decision-making include the process of managing resources to ensure effectiveness and security. This management process uses appropriate and effective procedures in accordance with standards, and the values that exist in society refer to human needs to achieve common goals. Antecedents for decision-making include used cases and technology. The consequences of decision-making include positive impacts such as readiness, experience, responsibility, and action according to emergency procedures. This analysis helps nurses understand concepts and make action decisions in the emergency room. It is recommended that nurses be aware of the characteristics of the situation and the technology used as a guide in performing such actions. More research is needed to analyze the needs needed in the decision-making of nurses' activities in the emergency room. © 2024, Malque Publishing. All rights reserved.
