Construction of Procedure Framework for Classifying Diagnoses Using International Disease Classification

Abstract

This study aims to construct a work procedure framework for classifying diagnoses based on the International Statistical Classification of Diseases and Related Health Problems. This classification system was developed by the World Health Organization (WHO) for categorizing injuries, diseases and health-care services. The WHO classifications are increasingly applied to the basic data of clinical research in Japan, including epidemiological investigation and medical insurance. The classification process should be properly executed independently of the classifier or classification environment. The WHO guidelines are intended to enable proper classification by all member states of the WHO. However, whether the descriptions in the guidelines are sufficient for work procedures has not been verified. This study clarifies the improvement points of the WHO guidelines and constructs a new work procedure framework for classifying diagnoses.
