目的：分析某三甲医院原发性支气管肺癌临床路径的实施效果，探索临床路径优化策略。方法：选择2016年收治的572例原发性支气管肺癌患者，其中314例为临床路径入径组，其余258例为未入径组，比较优化前后入径组和未入径组的性别、年龄、平均住院日、住院费用等。结果：按DRG分组细化临床路径管理后，住院费用管理较分组前有了较大的提升。结论：本次优化策略证明有效。

Objective：To analyze the implementation of the clinical pathway of primary bronchial lung cancer in a Tertiary Level A hospital and to explore the optimization strategies. Method：314 out of 572 patients with primary bronchial lung cancer who were admitted via clinical pathways were classified as intake group，and 258 were classified non-intake group. The gender，age，average length of stay，cost were compared before and after optimization between intake group and non-intake group. Results：After refining the clinical pathway using DRG，the management of cost was greatly improved. Conclusion：The optimization strategies proved effective.
