切实把握临床医学与ICD-10的关系

要使疾病相关分组系统在我国尽快推广使用就要提高ICD-10编码的准确率,编码人员必须加强临床医学知识的学习,结合ICD-10的编码原则,通过认真阅读病历再进行编码,临床医师也应了解ICD-10的分类轴心和规则,书写好病历.     

两种DRGs指标体系的绩效评价效果比较研究

目的应用传统与新型DRGs指标体系进行绩效评价效果比较研究,探讨新型DRGs指标体系应用价值。方法基于某省大数据平台的31家三级综合公立医院DRGs资料,分别采用传统与新型DRGs指标体系对之进行综合绩效评价,采用Pearson检验对医院排名进行相关性分析,通过专家咨询法论证两种指标体系。结果31家医院排名均发生了变化,超过一半的医院排名变化幅度超过10名。两种DRGs指标体系的医院排名不存在显著相关性（相关系数为-0.348,P=0.057）,即在实际评价效果上存在较大差异。新型DRGs评价指标体系的应用价值优于传统型。结论相较于传统DRGs指标体系,新型DRGs指标体系严格把控区域医疗质量指标,通过强化学科评价与费用控制,重视患者医疗质量,使评价更为科学、全面。     

DRGs视角下某医院医疗服务半径分析

目的通过分析某三甲医院的医疗服务半径及其变化趋势,为医院的科学发展规划提供决策依据。方法获取2016年至2019年的病案首页资料和DRGs运行指标,按患者现住址的行政区域统计分析各项业务指标的变化情况。结果医院各区域出院人次和DRGs组数均逐年增长,市本级患者构成比呈逐年下降趋势(χ趋势^2=441.74,P<0.001);区域CMI值表现为外市患者高于外县市高于市本级;MDCY(烧伤)、MDCN(女性生殖系统疾病及功能障碍)、MDCQ(血液、造血器官及免疫器官疾病和功能障碍)等MDC和整形烧伤科、神经外科、心胸外科等临床学科的区域辐射能力在增强。结论该院医疗服务辐射范围整体上有逐年扩张的趋势,未来需通过持续提升医疗质量和效率,积极推行分级诊疗,加强学科建设等措施,为本地市及周边区域的患者提供更加高质高效的医疗服务。     

基于DRGs的医疗服务绩效差异分析:以二级综合医院为例

目的对成都市二级民营综合医院与公立综合医院住院医疗服务绩效进行DRGs分析和比较,找出差异,提出建议。方法收集2019年成都市二级民营综合医院和二级公立综合医院住院病案首页数据,利用四川省DRGs应用平台进行分组计算,使用SPSS 20.0软件进行指标分析。结果成都市二级民营综合医院与二级公立综合医院2019年住院医疗服务绩效在医疗服务（总权重、覆盖DRGs组数和CMI值）、医疗效率（时间消耗指数、费用消耗指数）上并无显著差异,但在医疗质量与安全（中低风险及以下组病死率、标化病死率）上差异明显。结论二级民营综合医院与二级公立综合医院整体医疗服务差距逐渐缩小;二级民营综合医院内部发展不均衡,医疗质量与安全水平低于二级公立综合医院。建议持续提升民营综合医院服务能力,加强民营综合医院医疗质量与安全管理,同时政府须对民营医院强化监管。     

Differential network analysis reveals dysfunctional regulatory networks in gastric carcinogenesis

Gastric Carcinoma is one of the most common cancers in the world. A large number of differentially expressed genes have been identified as being associated with gastric cancer progression, however, little is known about the underlying regulatory mechanisms. To address this problem, we developed a differential networking approach that is characterized by including a nascent methodology, differential coexpression analysis (DCEA), and two novel quantitative methods for differential regulation analysis. We first applied DCEA to a gene expression dataset of gastric normal mucosa, adenoma and carcinoma samples to identify gene interconnection changes during cancer progression, based on which we inferred normal, adenoma, and carcinoma-specific gene regulation networks by using linear regression model. It was observed that cancer genes and drug targets were enriched in each network. To investigate the dynamic changes of gene regulation during carcinogenesis, we then designed two quantitative methods to prioritize differentially regulated genes (DRGs) and gene pairs or links (DRLs) between adjacent stages. It was found that known cancer genes and drug targets are significantly higher ranked. The top 4% normal vs. adenoma DRGs (36 genes) and top 6% adenoma vs. carcinoma DRGs (56 genes) proved to be worthy of further investigation to explore their association with gastric cancer. Out of the 16 DRGs involved in two top-10 DRG lists of normal vs. adenoma and adenoma vs. carcinoma comparisons, 15 have been reported to be gastric cancer or cancer related. Based on our inferred differential networking information and known signaling pathways, we generated testable hypotheses on the roles of GATA6, ESRRG and their signaling pathways in gastric carcinogenesis. Compared with established approaches which build genome-scale GRNs, or sub-networks around differentially expressed genes, the present one proved to be better at enriching cancer genes and drug targets, and prioritizing disease-related genes on the dataset we considered. We propose this extendable differential networking framework as a promising way to gain insights into gene regulatory mechanisms underlying cancer progression and other phenotypic changes.     

Do Diagnosis‐Related Group‐Based Payments Incentivise Hospitals to Adjust Output Mix?

This study investigates whether the diagnosis‐related group (DRG)‐based payment method motivates hospitals to adjust output mix in order to maximise profits. The hypothesis is that when there is an increase in profitability of a DRG, hospitals will increase the proportion of that DRG (own‐price effects) and decrease those of other DRGs (cross‐price effects), except in cases where there are scope economies in producing two different DRGs. This conjecture is tested in the context of the case payment scheme (CPS) under Taiwan's National Health Insurance programme over the period of July 1999 to December 2004. To tackle endogeneity of DRG profitability and treatment policy, a fixed‐effects three‐stage least squares method is applied. The results support the hypothesised own‐price and cross‐price effects, showing that DRGs which share similar resources appear to be complements rather substitutes. For‐profit hospitals do not appear to be more responsive to DRG profitability, possibly because of their institutional characteristics and bonds with local communities. The key conclusion is that DRG‐based payments will encourage a type of ‘product‐range’ specialisation, which may improve hospital efficiency in the long run. However, further research is needed on how changes in output mix impact patient access and pay‐outs of health insurance. Copyright © 2014 John Wiley & Sons, Ltd.     

从博弈论角度探究医疗支付运用DRGs支付方式的有效性

当前医改的一块"硬骨头"是如何改进医疗支付方式。笔者从博弈论角度探究医院管理中现行医疗支付方式存在的问题,探讨DRGs支付方式的有效性分析DRGs将有助于打破当前医院管理的"纳什均衡",并有利于增进医院管理的效率与公平,是医院管理的一种有效探索。     

两种医疗支付方式博弈理论分析

我国医疗保险支付方式改革的重点之一是将过去的按服务项目付费转变为按病种付费。通过建立两种医疗支付方式下医患、医院与医保局双方的博弈模型,分析了2种支付方式下博弈各方的行为特点。分析表明,按病种付费在控制不合理医疗费用上相较于按服务项目付费更优。不论在哪种支付方式下,优化医保监督管理方式使得监管难度降低的同时,增大处罚力度也是遏制医院不合理医疗的有效途径。     

病案摘录是DRGs研究课题的重要环节

单病种临床路径与DRGs成本控制在Chiari Ⅰ畸形合并脊髓空洞症手术治疗中的应用研究

目的通过对Chiari Ⅰ畸形合并脊髓空洞症手术治疗临床路径与DRGs(Diagnosis Related Groups)成本控制绩效分析,评价单病种临床路径和DRGs医疗成本控制应用于临床管理的效果.方法收集整理2005年10月至2006年9月脊髓空洞症科Chiari Ⅰ畸形合并脊髓空洞症手术治疗患者的信息,以其手术并发症发生率、平均住院天数、平均住院费用、患者满意率等作为评价指标,将实验组(应用临床路径和DRGs成本控制组)和对照组(未应用临床路径和DRGs成本控制组)进行对比分析.结果应用临床路径和DRGs成本控制的患者与未应用这一方式的患者之间在手术并发症发生率、平均住院时间、平均住院费用、患者满意率方面有统计学显著差异.结论单病种临床路径和DRGs成本控制模式应用于Chiari Ⅰ畸形合并脊髓空洞症手术治疗,可以明显促进CQI(Continuous Quality Improvement)、缩短平均住院时间,降低住院费用,提高患者满意率.
