──Exploratory and quantitative analysis──

Abstract

　　Purpose:The purpose of this study was to identify trends of academic terms used in the past decade along with collateral information for the Japan Society for Healthcare Administration.

Methods:Quantitative text analysis of the academic terms published in the Journal of the Japan Society for Healthcare Administration between January 2005 and December 2014 was performed to compare the number of terms by type and year.　In addition, groups of terms obtained by clustering were also performed on multiple correspondence analyses.

Results:Three terms, nursing, system and management, were the central keywords.　Terms related to the use of big data such as diagnosis procedure combination （DPC）, home medical care, home-visit nursing, management based on analysis, and medical care for foreigners tended to appear more often in 2010-14 than in 2005-09.

Discussion:Changes in and the characteristics of academic terms used by type and year are speculated to be related to the Japan’s situation, suggesting the necessity for new term selection, classification and explanation.
