探讨急诊科危重症患者的流行病学特点。

首先逐项统计急诊危重患者在就诊时间、分布地区、年龄、疾病谱的相关数据，再根据这些数据的规律特征，分析得出急诊科危重症患者在就诊时间、分布地区、年龄、疾病谱的特征及规律。

在就诊时间方面，正常工作时间段与非正常工作时间段就诊患者在数量上无明显差异；在就诊地区与年龄方面，来自农村的老年男性患者居多，其中70～79岁的患者数量最多；在疾病谱方面，占据前三位的疾病项为，循环系统疾病、呼吸系统疾病、和内分泌系统疾病。

根据以上数据，为急诊管理者在合理安排人力方面提供客观依据；在业务培训方面，指导急诊医护人员有针对性的加强"老年慢性病"的学习。

First of all, we count the data of emergency critically ill patients in visiting time, distribution area, age, disease spectrum, and then according to the law characteristics of these data, we can get the characteristics and rules of emergency critical patients in the time of treatment, distribution area, age, disease spectrum.
