Classification algorithm for discharge summary stored in hospital is proposed for advance the quality of medical care based on structured information. It provides similarity of morpheme word in discharge summary for each DPC (Diagnosis Procedure Combination) code, which the similarity is calculated based on SOAP (subjective, objective, assessment, and plan) information stored in electronic health record. Experimental classification results for 550 discharge summaries of 55 DPC codes taken in Kochi Medical School hospital show that accuracy of classification is 85% and that the same words are used in discharge summary of the same DPC codes. The proposed algorithm can be used for intercomparison study of words of discharge summary in Japan.
