The decision to not convey patients has become common in emergency medical services worldwide. A substantial proportion (12–51%) of the patients seen by emergency medical services are not conveyed by those services. The practice of non-conveyance is a result of the increasing and changing demands on the acute care system. Research focusing on the outcomes of the decision by emergency medical services to not convey patients is needed. The aim was to describe outcomes (emergency department visits, admission to in-hospital intensive care units and mortality, all within seven days) and their association with the variables (sex, age, day of week, time of day, emergency signs and symptoms codes, triage level colour, and destination) for non-conveyed patients. This was a prospective analytical study with consecutive inclusion of all patients not conveyed by emergency medical services. Patients were included between February 2016 and January 2017. The study was conducted in Region Örebro county, Sweden. The region consists of both rural and urban areas and has a population of approximately 295,000. The region had three ambulance departments that received approximately 30,000 assignments per year. The result showed that no patient received intensive care, and 18 (0.7%) patients died within seven days after the non-conveyance decision. Older age was associated with a higher risk of hospitalisation and death within seven days after a non-conveyance decision. Based on the results of this one-year follow-up study, few patients compared to previous studies were admitted to the hospital, received intensive care or died within seven days. This study contributes insights that can be used to improve non-conveyance guidelines and minimise the risk of patient harm.

急诊医疗服务 (EMS) 未传达的患者结局：一项为期一年的前瞻性研究

不运送病人的决定在世界各地的紧急医疗服务中变得很普遍。急诊医疗服务所接诊的患者中有很大一部分（12-51%）不是由这些服务转送的。非转运的做法是对急症护理系统的需求不断增加和变化的结果。需要重点研究紧急医疗服务部门决定不运送患者的结果。目的是描述结果（急诊科就诊、入院重症监护病房和死亡率，均在 7 天内）及其与变量（性别、年龄、星期几、一天中的时间、紧急体征和症状）的关联代码、分诊级别颜色和目的地）用于未转诊的患者。这是一项前瞻性分析研究，连续纳入了紧急医疗服务未转诊的所有患者。患者在 2016 年 2 月至 2017 年 1 月期间被纳入研究。该研究在瑞典厄勒布鲁地区进行。该地区包括农村和城市地区，人口约为 295,000。该地区有三个救护部门，每年接收约 30,000 份任务。结果显示，没有患者接受重症监护，18 名（0.7%）患者在不转送决定后的 7 天内死亡。年龄越大，在做出不接受转运决定后 7 天内住院和死亡的风险越高。根据这项为期一年的随访研究的结果，与以前的研究相比，很少有患者入院，接受重症监护或在 7 天内死亡。本研究提供的见解可用于改进非转运指南并最大程度地降低患者伤害的风险。
