Tittle: From Clinical Records to Research Databases: ICU Data Challenges
Abstract: The volume of data routinely collected in intensive care units (ICUs) has increased substantially with the widespread adoption of electronic health records (EHRs). Despite this abundance of data, transforming routinely collected clinical information into reliable evidence for research remains challenging. To facilitate secondary use of ICU data, several datasets have been extracted, anonymized, and made publicly available. However, the process of creating and using such datasets involves multiple layers of complexity. These challenges begin with ethical considerations and regulatory approvals, extend to technical and methodological issues during data extraction, harmonization, and database construction, and ultimately culminate in the difficulties of analyzing real-world data characterized by missingness, measurement variability, and multiple sources of bias. Through the example of an Austrian ICU dataset, this lecture explores the key steps from study planning to database construction and analysis.
Dr. med. univ. Rodemund Niklas, MSc, is a physician at the Department of Anaesthesiology and Intensive Care Medicine at Salzburg University Hospital, Paracelsus Medical University, Salzburg, Austria. His research focuses on the secondary use of routinely collected clinical data, particularly in intensive care medicine, and the methodological challenges and biases associated with real-world data. He is one of the creators of the Salzburg Intensive Care Database, a research initiative aimed at enabling data-driven research in critical care.
