概要 | Here we develop a hybrid methodology for the analysis of medical records that consist of clinicians’ notes (requesting for a scan) using statistical tools and Kohonen’s self-organizing map (SOM) text mining techniques to look for heretofore invisible patterns to save patients from unwarranted scans. The medical data derive from patients’ radiology department records where CT (Computed Tomography) scanning was used as part of a diagnostic exploration. The records are from the digital records of about 700 pediatric patients who underwent CT scanning (single and multiple) through a one-year period in 2004 at the Nagasaki University Medical Hospital in Japan. This approach led to a model based on SOM clusters and statistical analysis which allow for the prediction of when a particular medical screening procedure may be unnecessary. The procedure involves CT scans of patients. Note: This is important because radiation at levels ordinarily used for CT scanning may pose significant health risks especially to children. |
