目的: 探讨病种基础诊疗模块在费用管理中的应用效果,为病种基础诊疗模块的推广使用和费用管理建言献策。方法: 调取103例广西科技大学第二附属医院呼吸系统感染/炎症患儿（<17岁）的住院资料,对比分析病种基础诊疗模块应用前后患儿的住院天数、住院总费用、药费、药费占比及抗生素的使用情况。结果: 使用病种基础诊疗模块后,费用管理效果明显,DRG病组患儿的住院天数3d、住院总费用1799.23元、药费487.02元、药费占比32.47%,均低于应用前的5d、2429.85元、924.57元、39.02%（P<0.05）;抗生素的使用合理性94.44%高于应用前的81.63%（P<0.05）。结论: 使用病种基础诊疗模块进行费用管理,可规范临床诊疗行为,提升医疗服务质量,实现精准管理。

Objective: The paper explores the effect of disease basic diagnosis and treatment module in the cost management and proposes its application. Methods: The clinical data of 103 children with respiratory infection/inflammation (< 17 years old) who received inpatient treatment before and after the application of basic diseases diagnosis and treatment module in the Second Affiliated Hospital of Guangxi University of Science and Technology were collected. The changes of length of stay, total hospitalization cost, drug cost, proportion of drug cost and rational use of antibiotics were analyzed before and after the application. Results: After using the disease basic diagnosis and treatment module to manage the cost, the length of hospitalization of DRG was 3d, the total hospitalization cost was 1799.23 yuan, the drug cost was 487.02 yuan, and the drug cost accounted for 32.47%, which were lower than or shorter than before 5d, 2429.85 yuan, 924.57 yuan, 39.02% (P < 0.05). The rationality of antibiotic use was 94.44%, which was higher than 81.63% before application (P < 0.05). Conclusion: Using disease basic diagnosis and treatment module for cost management can standardize clinical diagnosis and treatment behavior, improve medical service quality and achieve accurate management.
