OBJECTIVES In the Multiple Myeloma clinical registry at Heidelberg University Hospital, most data are extracted from discharge letters. Our aim was to analyze if it is possible to make the manual documentation process more efficient by using methods of natural language processing for multiclass classification of free-text diagnostic reports to automatically(More)
Integration and analysis of clinical data collected in multiple data sources over a long period of time is a major challenge even when data warehouses and metadata registries are used. Since most metadata registries focus on describing data elements to establish domain consistent data definition and providing item libraries, hierarchical and temporal(More)

Systems medicine is the consequent continuation of research efforts on the road to an individualized medicine. Thereby, systems medicine tries to offer a holistic view on the patient by combining different data sources to highlight different perspectives on the patient's health. Our research question was to identify the main data types, modelling methods,(More)
Clinical registries are a powerful method to observe the clinical practice and natural disease history.

The study aims on comparing Bayley Scales of infant development third (Bayley-III) and Bayley second (Bayley-II) edition with special focus on patterns in the first year of life. Fifty-five premature infants (43 with low birth weight/LBW >1,499 g and 12 with very/extremely low birth weight/VLBW/ELBW <1,500 g) aged 7 months (corrected for prematurity) were(More)
PURPOSE An important part of the electronic information available in Hospital Information System (HIS) has the potential to be automatically exported to Electronic Data Capture (EDC) platforms for improving clinical research. This automation has the advantage of reducing manual data transcription, a time consuming and prone to errors process. However,(More)
