Secondary Health Data Linkage for Health Services Research: Prevalence and determinants of avoidable emergency department utilization

急诊和急症医学领域目前正在成长为德国的医学专业学科。2015年在柏林建立了临床专业的子专业。同时，研究结构也在不断发展，并且至关重要。在德国，常规数据的记录没有很好地标准化，也没有关于急诊科（ED）使用率和急诊科就诊前后护理途径的可靠数据。与德国相反，二级卫生保健数据的报告和联系是英美国家的普遍做法。澳大利亚特别实施了全国紧急部门信息系统（EDIS），并建立了与其他数据源的数据联系。在这个研究项目中，将分析澳大利亚涉及急诊科数据的二级保健数据，重点是估计发病率和评估可避免急诊科就诊的决定因素，以便制定以证据为基础的干预措施，减轻急诊科的负担。研究项目的另一个重要重点将是确定阻碍和促进成功实施急诊科信息和数据联系系统的因素，以确定可以转移到德国正在发展的联系系统的解决方案。因此，访问研究员将收集有关急诊和急症医学领域相关卫生保健数据的标准化、分析和报告领域的专门知识。获得的熟练程度将有助于在德国系统中及时和成功地实施这一重要的方法方法，特别是在德国柏林慈善大学医院急诊和急症医学部目前的研究小组中。

The field of Emergency and Acute Medicine is currently growing into a medical specialty discipline in Germany. A subspecialization on top of a clinical specialization has been established in Berlin 2015. Concurrently research structures are evolving and are of utmost importance. The documentation of routine data in Germany is not well standardized and no reliable data are available on Emergency Department (ED) utilization and pathways of care before and after an Emergency Department visit in Germany.As opposed to Germany, reporting and linkage of secondary health care data is common practice in Anglo-American countries. Australia especially implemented a nationwide Emergency Department Information System (EDIS) and data linkage to other data sources is well-established.In this research project linked secondary health care data involving ED data will be analyzed in Australia with the focus to estimate the prevalence and to assess determinants of avoidable ED visits in order to develop evidence-based interventions to disburden EDs.Another important focus of the research project will be to identify impeding and facilitating factors for a successful implementation of an Emergency Department information and data linkage system to identify solutions that can be transferred to an evolving linkage system in Germany.The visiting researcher will thus gather specific expertise in the field of standardization, analysis and reporting of linked health care data concerning the field of Emergency and Acute Medicine. The acquired proficiencies will facilitate the timely and successful implementation of this important methodological approach in the German system in general, and specifically in the current research group at the Department of Emergency and Acute Medicine at the Charité University Hospital in Berlin, Germany.
