Exploratory Univariate Analysis on the Characterization of a University Hospital: A Preliminary Step to Data-Mining-Based Hospital Management Using an Exploratory Univariate Analysis of a University Hospital

摘要

Rapid progress in information technology allows us to store all the information of a hospital in a hospital information system, including management data, patient records, discharge summaries and laboratory data. Although those data have not been reused to date, the stored data can contribute to an analysis of hospital management. In this paper, the discharge summaries of Chiba University Hospital, which has been stored since 1980’s, were analyzed to characterize the university hospital. This paper focuses on using exploratory univariate analysis to show that the major reason for admissions in this university hospital is neoplasm and the distribution on length of stay and NHI (National Health Insurance, Japan) points to total cases and neoplasm followed logarithmic normal distributions, which are supported by descriptive statistics.
