目的：探索医院感染及其相关危险因素与DIP结算差额的关联性,为医疗卫生机构在提升医疗质量安全过程中实现DIP结算效益最大化提供借鉴参考。方法：选取2021年某县级综合医院40572名医保出院患者为研究对象,运用SPSS 22.0分析医院感染及其相关危险因素对DIP结算差额的影响。结果：患者年龄、住院天数及侵入性手术或操作对DIP结算差额存在正向影响,医院感染、抗菌药物使用及多重耐药菌感染对DIP结算差额存在负向影响。结论：在DIP医保付费模式下,医院应提升感染防控管理能力,降低DIP结算差额,提高经济效益。

Objective: The paper explores the correlation between nosocomial infection and its related risk factors and DIP settlement results, and to provide the reference for medical and health institutions to maximize the benefits of DIP settlement in the process of improving medical quality and safety. Methods: A total of 40572 medical insurance patients discharged from a county-level general hospital in 2021 were selected as the research objects, and SPSS 22.0 was used to analyze the influence of nosocomial infection and its related risk factors on the balance of DIP settlement. Results: Patient age, length of hospital stay, and invasive surgery or operation had a positive impact on the DIP settlement balance, while nosocomial infection, antimicrobial use and multidrug-resistant bacterial infection had a negative impact on the DIP settlement balance. Conclusion: Under the DIP medical insurance payment model, the hospital should improve the infection prevention and control management ability, reduce the DIP settlement balance, and increase economic benefits.
