Abstract


Appropriate management at the level of each department unit is needed to improve the quality of services and the effectiveness in administration of medical facilities. However, a comparative analysis among departments is not straightforward because of their heterogeneity in patient composition and medical functions.

We conducted a similarity evaluation of patient images of the hospital department using the similarity index.

We attempted to identify medical departments with a similar patient composition. The Cλ values ranged from 0.826 to 0.97 in the H001 and H002 departments of internal medicine, the H005 and H006 departments of respiratory diseases, and the H009 and H010 departments of respiratory internal medicine. This indicates that the patient profiles were similar among those six departments. The Cλ value in the H004 department of respiratory diseases and the H008 department of surgery was 0.081, which shows that the departments were the most dissimilar. The Cλ values in the H004 department of respiratory diseases and the other nine departments were in the range of 0.081 to 0.321, which indicates that this department had different patient profiles to those of other hospital departments.

 

Keywords: similarity index • Cλ• department • Medical information • DPC date

In this study, we developed benchmark analyses, which can be used in the management of hospital departments where the range of disease and patient composition are similar. We believe that using comparative analyses among groups whose similarity is confirmed by similarity indices offers an effective means of analysing the current situation regarding medical services and evaluating the quality of such services.
