【摘要】 在医疗费用控制与医疗服务效率提升的背景下，DRG支付方式作为先进的医疗保险支付机制，在全球范围内被广泛应用。DRG支付方式的核心在于将患者根据其临床诊断、治疗过程及资源消耗因素归类至不同的疾病诊断相关组，从而实现按组付费而非按服务项目逐一计费。这种方式旨在通过标准化支付标准，减少过度医疗，优化医院运营效率和服务质量。更多还原

【Abstract】 Under the background of controlling healthcare costs and improving the efficiency of medical services, Diagnosis Related Group(DRG) payment systems, as an advanced health insurance payment mechanism, have been widely adopted globally.The core of DRG payment lies in categorizing patients into different diagnosis-related groups based on their clinical diagnosis,treatment process, and resource consumption factors. This enables payment by group rather than billing for each individual service item. This approach aims to reduce overmedicalization and optimize hospital operational efficiency and service quality through standardized payment criteria.更多还原
