分析30～59岁人群死亡患者疾病排序变化情况，从而对医院各科室间的医疗资源分配进行有针对性的调整。

回顾性收集1992年至1996年以及2012年至2017年两个时间段各五年30～59岁死亡患者病案首页数据，抽取患者主要诊断、年龄、转归情况字段进行分析。

经过20年的变化，30～59岁死亡患者的疾病结构存在显著性差异(χ²＝165.33 ，P<0.05)，循环系统疾病以及呼吸系统疾病所占比例上升明显，分别上升13.9及6.9个百分点；肿瘤疾病占比下降7.4个百分点，其他疾病顺位也有不同程度改变。

医院和社会应该根据疾病顺位的变化规律和特点，重视30～59岁患者循环系统疾病的早期诊断与急救知识教育，合理分配现有卫生资源，降低30～59岁患者患病死亡的风险。

To analyze the disease pattern changes in death patients aged from 30 to 59 years so as to provide basis for adjusting the allocation of medical resources in departments of the hospital.

Retrospective collection was done on data of death patients aged 30-59 years in home page of medical records from two Five-Year Plan periods (1992-1996 and 2012-2017). Main diagnosis, age and prognosis of the patients were analyzed.

After 20 years, there was a significant difference in disease pattern of death patients aged 30-59 years (χ²=165.33, P<0.05). Circulation system diseases and respiratory diseases were increased by 13.9% and 6.9% respectively. The proportion of tumor disease was reduced by 7.4%. The rank of other diseases also changed at various degrees.

Based on the changing pattern and characteristics of the disease, hospitals and society should pay attention to early diagnosis and prevention of circulatory disease and reasonably allocate the existing health resources and hence reduce the risk of death in patients aged 30-59 years.
