The adequacy of work processes in healthcare services contributes to the quality of care provided to the patient. However, in emergency units, overcrowding is a constant reality, resulting in the lack of materials and long waiting lines. Taking this into consideration, this study aimed to map and analyze the value stream of patients classified as blue, green, or yellow in a Referral Emergency Unit. The evaluation research with analysis of processes was carried out in a teaching hospital on 30 patients seen at the emergency service. Value Stream Maps were drawn and the times involved in the process were calculated. Wastes and their possible causes were identified. A total of 13 maps were created and the mean process time between the activities involved in the process ranged between 7.3' and 114.0'; the interruption time, between 0' and 27.6'; the waiting time, between 43.2' and 507.5'; and the lead time between 56.6' and 638.0' min. Some causes of waste were: high demand from patients; a shortage of personnel and offices. Following the Ishikawa Diagram, most of the waste is found regarding methods, human resources, and physical structure.
医疗服务中的工作流程是否充分，会直接影响到为患者提供的护理质量。然而，在急诊室，过度拥挤是一种常态，这导致了材料短缺和长时间的候诊队伍。有鉴于此，本研究旨在对被归类为蓝色、绿色或黄色的患者在转诊急救中心的价值流进行映射和分析。这项评估研究对一家教学医院的急诊服务中的 30 名患者进行了流程分析。绘制了价值流图，并计算了流程中涉及的时间。确定了浪费及其可能的原因。共创建了 13 个图，流程中各活动之间的平均处理时间在 7.3' 到 114.0' 之间；中断时间在 0' 到 27.6' 之间；等待时间在 43.2' 到 507.5' 之间；提前时间在 56.6' 到 638.0' 之间。一些浪费的原因是：患者需求高；人员和办公室短缺。根据石川图，大多数浪费是在方法、人力资源和物理结构方面。
