基于院级DRG分组诊疗数据知识库的实时分组管理研究

为进一步激发疾病诊断相关分组(DRG)对医疗资源的管理效能和对诊疗行为的规范作用,提出了一种实时分组方案。根据医院已出院患者的临床诊断、治疗方案等诊疗数据,以大数据统计方式,构建DRG分组诊疗数据知识库,并提出患者诊疗分组、科室出院分组、病案编码分组和医保审核分组四级实时分组方法。实践后成效明显。DRG分组诊疗数据知识库契合医院实际,实时分组方案贯穿患者主要诊断的产生、修订全过程,可实现DRG事前、事中、事后管理,但医疗机构需注意甄别偏差数据,确保临床行为规范,提高DRG管理主动性。

Real-time electromagnetic transient simulation algorithm for integrated power systems based on network level and component level parallelism

The analysis and simulation of power system are becoming more and more challenging as the complexity of system topology and components has been increased. In this paper, a hybrid parallel algorithm is proposed for the real-time electromagnetic transient simulation （EMTS） of integrated power systems containing multiphase machines. The proposed algorithm is com- posed of a novel network partition method called component level parallelization and the Multi-Area Thevenin Equivalent （MATE） method, which extends the flexibility of the network partition in parallel simulation. Moreover, several methods are developed to enhance the efficiency of the communication and computation. Power systems with up to 410 single-phase elec- trical nodes and 336 switches are simulated in a time step of 50 ~ts to validate the proposed algorithm.
