Invited Talk 5 - Information extraction from unstructured text data in the electronic medical records-status quo and challenges
許明暉 數據長 (臺北醫學大學數據處 )
Abstract
In the past ten years, with the continuous advancement and adoption of health information technology, medical institutions around the world have acquired a large amount of electronic medical record (EMR) data after long-term collection. For clinical scientific research, EMR data has the advantages of low cost and timely compared with data obtained in the clinical trial. At present, more and more studies have used EMR data in clinical research such as efficacy analysis and outcome analysis.
Health data includes personal health data from mobile devices, hospital clinical data, genetic data, and public data for disease prevention and control. The integration of data from the multiple sources can provide the fundamentals for health promotion, disease prevention, and national health strategies.
EMR has the characteristics of diversity, incompleteness and redundancy, which make it difficult to carry out data analysis directly. It is necessary to preprocess the source data to improve data quality. Different types of data require different processing technologies. Most structured data commonly needs classic preprocessing technologies, including data cleansing, data integration, data transformation, and data reduction. For semi-structured or unstructured data, such as medical text, it requires more complex and challenging processing methods. This presentation will focus on information extraction text data in EMR. Text in EMRs is accessible, especially with open-source information extraction algorithms, and significantly improves case detection when combined with codes. However, more harmonization of reporting within EMR studies is needed.
Biography
Min-Huei Marc Hsu is a Professor of the Graduate Institute of Data Science at Taipei Medical University. Dr. Hsu has dedicated himself to the adoption of health information technology. He has been involved deeply in digital health projects in Taiwan. He is one of the essential promoters of Taiwan's National EMR exchange program. Dr. Hsu was appointed as Director of Medical Informatics Center at the Ministry of Health and Welfare of Taiwan in March 2011. Before the MOHW appointment, Dr. Hsu served as CIO at Taipei Medical University and also a Consultant Neurosurgeon at Wanfang Hospital (a 746-bed hospital affiliated to Taipei Medical University). Besides, he is author and co-author of more than 80 papers and articles in international conferences and scientific journals, focusing on health data, health information technology, e-health, electronic medical record system, hospital information management, and patient safety.
